Effect of intraoperative injection of esketamine on postoperative analgesia and postoperative rehabilitation after cesarean section

BACKGROUND Following cesarean section,a significant number of women encounter moderate to severe pain.Inadequate management of acute pain post-cesarean section can have far-reaching implications,adversely impacting maternal emotional wellbeing,daily activities,breastfeeding,and neonatal care.It may also impede maternal organ function recovery,leading to escalated opioid usage,heightened risk of postpartum depression,and the development of chronic postoperative pain.Both the Chinese Enhanced Recovery After Surgery(ERAS)guidelines and the American ERAS Society guidelines consistently advocate for the adoption of multimodal analgesia protocols in post-cesarean section pain management.Esketamine,functioning as an antagonist of the N-Methyl-D-Aspartate receptor,has been validated for pain management in surgical patients and has exhibited effectiveness in depression treatment.Research has suggested that incorporating esketamine into postoperative pain management via pain pumps can lead to improvements in short-term depression and pain outcomes.This study aims to assess the efficacy and safety of administering a single dose of esketamine during cesarean section.AIM To investigate the effect of intraoperative injection of esketamine on postoperative analgesia and postoperative rehabilitation after cesarean section.METHODS A total of 315 women undergoing elective cesarean section under combined spinal-epidural anesthesia were randomized into three groups:low-dose esketamine(0.15 mg/kg),high-dose esketamine(0.25 mg/kg),and control(saline).Postoperative Visual Analog Scale(VAS)scores were recorded at 6 hours,12 hours,24 hours,and 48 hours.Edinburgh Postnatal Depression Scale(EPDS)scores were noted on 2 days,7 days and 42 days.Ramsay sedation scores were assessed at specified intervals post-injection.Postoperative adverse reactions were also recorded.RESULTS Low-dose group and high-dose group compared to control group,had significantly lower postoperative VAS pain scores at 6 hours 12 hours,and 24 hours(P<0.05),with reduced analgesic usage(P<0.05).EPDS scores and postpartum depression rates were significantly lower on 2 days and 7 days(P<0.05).No significant differences in first exhaust and defecation times were observed(P>0.05),but ambulation times were shorter(P<0.05).Ramsay scores were higher at 5 minutes,15 minutes,and upon room exit(P<0.05).Low-dose group and high-dose group had higher incidences of hallucination,lethargy,and diplopia within 2 hours(P<0.05),and with low-dose group had lower incidences of hallucination,lethargy,and diplopia than high-dose group(P<0.05).CONCLUSION Esketamine enhances analgesia and postpartum recovery;a 0.15 mg/kg dose is optimal for cesarean sections,balancing efficacy with minimized adverse effects.

Effect of different anesthetic modalities with multimodal analgesia on postoperative pain level in colorectal tumor patients

BACKGROUND According to clinical data,a significant percentage of patients experience pain after surgery,highlighting the importance of alleviating postoperative pain.The current approach involves intravenous self-control analgesia,often utilizing opioid analgesics such as morphine,sufentanil,and fentanyl.Surgery for colo-rectal cancer typically involves general anesthesia.Therefore,optimizing anes-thetic management and postoperative analgesic programs can effectively reduce perioperative stress and enhance postoperative recovery.The study aims to analyze the impact of different anesthesia modalities with multimodal analgesia on patients'postoperative pain.AIM To explore the effects of different anesthesia methods coupled with multi-mode analgesia on postoperative pain in patients with colorectal cancer.METHODS Following the inclusion criteria and exclusion criteria,a total of 126 patients with colorectal cancer admitted to our hospital from January 2020 to December 2022 were included,of which 63 received general anesthesia coupled with multi-mode labor pain and were set as the control group,and 63 received general anesthesia associated with epidural anesthesia coupled with multi-mode labor pain and were set as the research group.After data collection,the effects of postoperative analgesia,sedation,and recovery were compared.RESULTS Compared to the control group,the research group had shorter recovery times for orientation,extubation,eye-opening,and spontaneous respiration(P<0.05).The research group also showed lower Visual analog scale scores at 24 h and 48 h,higher Ramany scores at 6 h and 12 h,and improved cognitive function at 24 h,48 h,and 72 h(P<0.05).Additionally,interleukin-6 and interleukin-10 levels were significantly reduced at various time points in the research group compared to the control group(P<0.05).Levels of CD3+,CD4+,and CD4+/CD8+were also lower in the research group at multiple time points(P<0.05).CONCLUSION For patients with colorectal cancer,general anesthesia coupled with epidural anesthesia and multi-mode analgesia can achieve better postoperative analgesia and sedation effects,promote postoperative rehabilitation of patients,improve inflammatory stress and immune status,and have higher safety.

Ultrasound-guided serratus anterior plane block enhances postoperative analgesia and recovery in thoracoscopic surgery

BACKGROUND The serratus anterior muscle,located in the lateral aspect of the thorax,plays a crucial role in shoulder movement and stability.Thoracoscopic surgery,while minimally invasive,often results in significant postoperative pain,complicating patient recovery and potentially extending hospital stays.Traditional anesthesia methods may not adequately address this pain,leading to increased complications such as agitation due to inadequate pain management.AIM To evaluate the application value of ultrasound-guided serratus anterior plane block(SAPB)in patients undergoing thoracoscopic surgery,focusing on its effects on postoperative analgesia and rehabilitation.METHODS Eighty patients undergoing thoracoscopic surgery between August 2021 and December 2022 were randomly divided into two groups:An observation group receiving ultrasound-guided SAPB and a control group receiving standard care without SAPB.Both groups underwent general anesthesia and were monitored for blood pressure,heart rate(HR),oxygen saturation,and pulse.The primary outcomes measured included mean arterial pressure(MAP),HR,postoperative visual analogue scale(VAS)scores for pain,supplemental analgesic use,and incidence of agitation.RESULTS The observation group showed significantly lower cortisol and glucose concentrations at various time points post-operation compared to the control group,indicating reduced stress responses.Moreover,MAP and HR levels were lower in the observation group during and after surgery.VAS scores were significantly lower in the observation group at 1 h,4 h,6 h,and 12 h post-surgery,and the rates of analgesic supplementation and agitation were significantly reduced compared to the control group.CONCLUSION Ultrasound-guided SAPB significantly improves postoperative analgesia and reduces agitation in patients undergoing thoracoscopic surgery.This technique stabilizes perioperative vital signs,decreases the need for supplemental analgesics,and minimizes postoperative pain and stress responses,underscoring its high application value in enhancing patient recovery and rehabilitation post-thoracoscopy.

Erector Spinae Plane Block Combined with Serratus Anterior Plane Block Versus Thoracic Paravertebral Block for Postoperative Analgesia and Recovery After Thoracoscopic Surgery:A Randomized Controlled Non-inferiority Clinical Trial

Objective This study aimed to compare the postoperative analgesia and recovery of ultrasound-guided erector spinae plane block combined with serratus anterior plane block(ESPB combined with SAPB)versus thoracic paravertebral block(PVB)after thoracoscopic surgery.Methods Ninety-two patients who underwent video-assisted thoracoscopic surgery(VATS)were randomly divided into group S(n=46)and group P(n=46).After anesthesia induction,the same anesthesiologist performed ultrasound-guided ESPB at T5 and T7 levels combined with SAPB at the level of the fifth rib in the midaxillary line in group S and ultrasound-guided PVB at T5 and T7 levels in group P.Patients in both groups were given 40 mL of 0.4%ropivacaine.Eighty-six patients completed the study(group S,n=44;group P,n=42).The morphine consumption,visual analogue scale(VAS)scores at rest and coughing,and frequency of remedial analgesia were recorded at 1,2,4,8,and 24 h postoperatively.Pulmonary function parameters were recorded at 1,4,and 24 h postoperatively,and the quality of recovery(QoR)-15 score at 24 h postoperatively.The adverse effects,duration of chest tube drainage and length of stay were also recorded.Results The morphine consumption at postoperative 4 and 8 h and the incidence of ipsilateral shoulder pain(ISP)were significantly lower in group S than in group P.The QoR-15 questionnaire score at postoperative 24 h was significantly lower in group P than in group S(P<0.05).The morphine consumption was lower at 24 h postoperatively in group S than in group P,with no significant difference found yet.The morphine consumption at other observed times,VAS scores,pulmonary function parameters,frequency of remedial analgesia,duration of chest tube drainage,length of stay,and incidence of other adverse events were comparable between group S and group P.Conclusion Ultrasound-guided ESPB combined with SAPB is non-inferior to PVB in terms of morphine consumption at postoperative 24 h and postoperative recovery.But,this approach can significantly reduce morphine consumption in the early postoperative period(0–8 h)after thoracoscopy with lower incidence of ISP.It is a simpler and safer operation.

Effect of Preemptive Ketamine Administration on Postoperative Visceral Pain after Gynecological Laparoscopic Surgery

The pain following gynecological laparoscopic surgery is less intense than that following open surgery; however, patients often experience visceral pain after the former surgery. The aim of this study was to determine the effects of preemptive ketamine on visceral pain in patients undergoing gynecological laparoscopic surgery. Ninety patients undergoing gynecological laparoscopic surgery were randomly assigned to one of three groups. Group 1 received placebo. Group 2 was intravenously injected with preincisional saline and local infiltration with 20 m L ropivacaine（4 mg/m L） at the end of surgery. Group 3 was intravenously injected with preincisional ketamine（0.3 mg/kg） and local infiltration with 20 m L ropivacaine（4 mg/m L） at the end of surgery. A standard anesthetic was used for all patients, and meperidine was used for postoperative analgesia. The visual analogue scale（VAS） scores for incisional and visceral pain at 2, 6, 12, and 24 h, cumulative analgesic consumption and time until first analgesic medication request, and adverse effects were recorded postoperatively. The VAS scores of visceral pain in group 3 were significantly lower than those in group 2 and group 1 at 2 h and 6 h postoperatively（P〈0.05 and P〈0.01, respectively）. At 2 h and 6 h, the VAS scores of incisional pain did not differ significantly between groups 2 and 3, but they were significantly lower than those in group 1（P〈0.01）. Groups 1 and 2 did not show any differences in visceral pain scores at 2 h and 6 h postoperatively. Moreover, the three groups showed no statistically significant differences in visceral and incisional pain scores at 12 h and 24 h postoperatively. The consumption of analgesics was significantly greater in group 1 than in groups 2 and 3, and the time to first request for analgesics was significantly longer in groups 2 and 3 than in group 1, with no statistically significant difference between groups 2 and 3. However, the three groups showed no significant difference in the incidence of shoulder pain or adverse effects. Preemptive ketamine may reduce visceral pain in patients undergoing gynecological laparoscopic surgery.

Early and Late Postoperative Pain and Side Effects after Mastectomy: A Comparison of Ketamine and Thiamylal Administered for Anesthetic Induction

Objective: To compare acute and long-term postoperative pain and side effects in patients undergoing mastectomy for breast cancer under general anesthesia induced with ketamine or thiamylal. Methods: Twenty four ASA physical status I-III patients undergoing mastectomy were randomly assigned to one of two groups. Ketamine group received intravenous ketamine, 1 mg/kg, and thiamylal group received intravenous thiamylal, 4 mg/kg, at the induction of general anesthesia. Anesthesia was maintained with sevoflurane, N2O and fentanyl. The intensity of pain was assessed by using visual analog scale (VAS) 3 and 16 hr and 2, 3 and 4 weeks after surgery. Postoperative side effects, including nausea, vomiting and hallucination were also recorded. Results: At 16 hr after surgery, VAS in ketamine group was significantly lower than that in thiamylal group. However, there were no statistically significant differences between the two groups in the VAS at 3 hr and 2, 3 and 4 weeks after surgery. There were no differences in the incidence of side effects such as nausea, vomiting and hallucination between the two groups. Conclusion: Intravenous ketamine at the induction of anesthesia could reduce acute postoperative pain but not long-term pain after mastectomy.

Ultrasound-guided Transversus Abdominis Plane Block Improves Postoperative Analgesia and Early Recovery in Patients Undergoing Retroperitoneoscopic Urologic Surgeries:A Randomized Controlled Double-blinded Trial

Objective To evaluate the effects of ultrasound-guided transversus abdominis plane(TAP) block on postoperative analgesia and early recovery in patients undergoing retroperitoneoscopic urologic surgeries.Methods This was a randomized,controlled,double-blinded trial.Eligible patients scheduled for retroperitoneoscopic urologic surgeries were randomly assigned to two groups.Group TAP received ultrasound-guided TAP block with 0.5% ropivacaine 20 ml at 30 minutes before surgery,and Group C received TAP sham block with normal saline.All patients received retroperitoneoscopic urologic surgeries under general anesthesia.The primary outcome was the severity of pain after surgery.Secondary outcomes included opioids consumption,analgesics,postoperative nausea and vomiting,time to Foley catheter removal and to passage of flatus,length of post-anesthesia care unit stay and hospital stay.Results Eighty patients completed the study,forty cases in each group.Compared to the Group C,the Group TAP had lower visual analogue scale pain scores within two postoperative days(all P<0.05).They also had less consumption of intraoperative fentanyl(2.0±0.5 vs. 3.8±0.7 μg/kg,P<0.05),reduced incidence of postoperative rescue analgesic usage(12.5% vs. 45.0%,P<0.05),and lower incidence of postoperative nausea and vomiting within postoperative 48 hours(12.5% vs. 25.0%,P<0.05) when compared to the Group C.In addition,Group TAP had a shortened post-anesthesia care unit stay(25±8 vs. 49±12 minutes,P<0.05),and a greater proportion of patients discharged within postoperative three days(57.5% vs. 35.0%,P<0.05).Conclusion Preoperative ultrasound-guided TAP block is an effective technique to improve postoperative analgesia and early recovery in patients undergoing retroperitoneoscopic urologic surgeries.

Comparative efficacy of ketamine,lidocaine,acetaminophen,and dexmedetomidine combined with morphine patient-controlled analgesia in treating opium-addicted patients undergoing tibia fracture surgery:A randomized clinical trial

Objective:To compare the effect of ketamine,lidocaine,acetaminophen,and dexmedetomidine combined with morphine patient-controlled analgesia for opium addicts after tibial fracture surgery.Methods:This double-blind clinical trial included opium-addicted patients undergoing tibia fracture surgery.Patients were recruited and randomized to four different groups including the ketamine group,the lidocaine group,the acetaminophen group,and the dexmedetomidine group.The hemodynamic parameters such as heart rate(HR),mean arterial pressure,and arterial SaO2,alongside visual analog scale pain scores,sedation assessed by Ramsay score,nausea and vomiting,and opioid use were recorded and compared among the four groups.Results:This study included 140 patients,aged 37(32,41)years,with 92 males and 48 females,and each group had 35 patients.Dexmedetomidine-sedated subjects had the lowest blood pressure from 1 to 24 h after surgery,decreased HR at 12 and 24 h after surgery,and more satisfactory sedation(P<0.05).Notwithstanding no significant difference was noted in the pain scores,or nausea and vomiting among the groups(P>0.05).Conclusions:Dexmedetomidine has a better sedation effect compared to ketamine,lidocaine,and acetaminophen for pain control,but the final choice hinges on the patients’physical condition and the anesthesiologist's preference.Clinical registration:It is registered in Iranian Registry Clinical Trial by code IRCT20141209020258N146.

Administration of Nebulised Ketamine for Managing Pain in the Intensive Care Unit of Obstetrics and Gynaecology

Introduction: The use of inhaled ketamine to manage a variety of painful conditions has been endorsed by the American College of Emergency Physicians and the American Academy of Emergency Medicine. Nebulized analgesia has multiple benefits, including rapid, effective and titratable analgesic delivery. The aim of our study is to assess the efficacy and safety of intranasal analgesic-dose ketamine compared to multimodal analgesia in patients presenting with acute postoperative pain or headache after a spinal anaesthetic in the intensive care unit of obstetrics and gynaecology. Materials and Methods: This was a prospective descriptive study, with hospital Ethics Committee approval and written informed consent from study participants. We compared the effect of nebulized ketamine and multimodal analgesia postoperatively in 120 patients belonging to the physical status I - II of the American Society of Anesthesiologists, in the intensive care unit of obstetrics and gynaecology, at the Ibn Rochd University Hospital Center in Casablanca from June 2021 to June 2022. Results: We included 120 patients in our study divided into two groups of 60 patients: the average age was 35 years, with extremes ranging from 18 to 45 years, All patients were hospitalized for postoperative care: all women underwent locoregional anaesthesia with a standard dose according to the service protocol (10 mg of bupivacaine, 25γ of fentanyl, 100γ of morphine), where pain was the common denominator. Among these patients, 59 were admitted for management of postpartum haemorrhage, 43 for postoperative monitoring, 15 for post-spinal anaesthesia headache and 3 for pelviperitonitis. The results of the pain assessment 30 minutes after the ketamine nebulization were marked by a request for analgesia in 12 patients, which is 20% of group A, including 5 patients, whose visual analogue scale (VAS) on admission was between 5 and 7, and 7 patients whose VAS at admission was ≥8;all these patients received a second dose of ketamine by nebulization;the evaluation 30 min after the second dose was marked by a request for analgesia in 4 patients, which is 7% of Group A;in all these patients the VAS at admission was ≥8. Of the total number of patients of Group A, only 4 received morphine when they were requested for analgesia after the second dose of nebulized ketamine. Conclusion: The primary outcome of nebulized ketamine use is a significant reduction in VAS pain score. We believe that nebulized ketamine has a potential effect of reducing pain in the intensive care unit of obstetrics and gynaecology;this may be an additional analgesic modality for clinicians to provide rapid, effective and non-invasive pain relief.

Thoracic Epidural Morphine for Postoperative Analgesia after Hemiclamshell Incision in Castleman Disease

The hemiclamshell incision is a valid but infrequent surgical alternative for the resection of tumors from mediastinum. This point makes this approach impossible to be studied under a randomized controlled trial. The triple association of thoracotomy, sternotomy and cervicothomy makes the hemiclamshell approach a high intensity postoperative pain surgery. However, there is no published data on this topic, and the reviewed articles only mention the analgesic regimens as a secondary point. Indeed, no author defines the best epidural drugs mixture for the patients. Multimodal analgesic regimen based on regional anesthesia should be used. Based on the recent advances on spinal opioids, morphine could be a good choice as epidural coadjutant to local anesthetics for hemiclamshell incision.

Intrathecal morphine vs femoral nerve block for postoperative-analgesia after total knee arthroplasty:A two-year retrospective analysis

AIM To compare the efficacy of intrathecal morphine and single shot femoral nerve block for patients undergoing primary total knee arthroplasty.METHODS Data was extracted from electronic medical records and case-paper record files of patients who underwent unilateral primary total knee arthroplasty under spinal anesthesia using bupivacaine 12.5 mg with intrathecal morphine(ITM) 0.2 mg and under general anesthesia(GA) with single shot femoral nerve block(FNB) using 20 m L 0.5% bupivacaine at our hospital in 2013 and 2014.All patients had received peri-articular infiltration as per the hospital protocol.Data for gender,age,weight,American Society of Anesthesiologists status,total surgical time,postoperative pain score using visual analogue scale(VAS) from 1 to 10 at 6 h,12 h and 24 h postoperatively,24 h opioid consumption,use of oral multimodal analgesia,postoperative high dependency unit(HDU) admission and the time to discharge from the hospital was collected.The data was analyzed using Mann-Whitney U test for continuous variables and Fischer's exact-t-test for categorical variables.RESULTS Twenty-two patients in ITM group and 32 patients in FNB group were analyzed.Median pain scores using VAS in ITM group were significantly lower at 6 h(0.0 vs 2.0,P<0.001),12 h(0.0 vs 2.0,P<0.001) and 24 h(0.0 vs 2.0,P<0.001) postoperatively.Also,postoperative morphine consumption in ITM group was significantly lower(P<0.001).However,median of nonsteroid anti-inflammatory drug unit requirement in 24 h postoperatively was statistically significant higher in ITM compared to FNB group(2.0 vs 1.0,P=0.025).The difference in postoperative paracetamol consumption in 24 h was not statistically significant(P=0.147).There was no significant difference in the postoperative HDU admission or time to discharge from the hospital.No respiratory depression in either group was noticed.CONCLUSION The ITM group patients had much lower pain scores and morphine requirement in the first 24 hour postoperatively compared to FNB group.

Safety of applying midazolam-ketamine-propofol sedation combination under the supervision of endoscopy nurse with patient-controlled analgesia pump in colonoscopy

AIM To compare the results of midazolam-ketaminepropofol sedation performed by an endoscopy nurse and anaesthetist during colonoscopy in terms of patient satisfaction and safety.METHODS American Statistical Association(ASA) Ⅰ-Ⅱ 60 patients who underwent colonoscopy under sedation were randomly divided into two groups: sedation under the supervision of an anaesthetist(SSA) and sedation under the supervision of an endoscopy nurse(SSEN). Both groups were initially administered 1 mg midazolam, 50 mg ketamine and 30-50 mg propofol. Continuation of sedation was performed by the anaesthetist in the SSAgroup and the nurse with a patient-controlled analgesia(PCA) pump in the SSEN group. The total propofol consumption, procedure duration, recovery times, pain using the visual analogue scale(VAS) and satisfaction score of the patients, and side effects were recorded. In addition, the patients were asked whether they remembered the procedure and whether they would prefer the same method in the case of re-endoscopy.RESULTS Total propofol consumption in the SSEN group was significantly higher(P < 0.05) than that in the SSA group. When the groups were compared in terms of VAS score, recovery time, patient satisfaction, recall of the procedure, re-preference for the same method in case of re-endoscopy, and side effects, there were no significant differences(P > 0.05) between the two groups. No long-term required intervention side effects were observed in either group.CONCLUSION Colonoscopy sedation in ASA Ⅰ-Ⅱ patients can be safely performed by an endoscopy nurse using PCA pump with the incidence of side effects and patient satisfaction levels similar to sedation under anaesthetist supervision.

Effect of thoracic epidural analgesia and sympathetic nerve block on postoperative hypertension in patients with patent ductus arteriosus

Objective To investigate the effects of thoracic epidural analgesia on postoperat ive hypertension in patients with PD A.Methods48cases of PDA were randomly divided into NTEA group(n =22)and TEAgroup(n =26).General anesthesia was used for NTE Agroup,and intramuscular injection of peth idine 1mg /kg was used when postopera tive pain occurs;general anesthesia combined with thoracic epidural anesthesia were used for TEAgroup,a nd thoracic epidural analgesia was u sed for postoperative analgesia.BP,HR,RR,SpO 2 ,EKG were monitored during and after operatio n,angiotenic was used when the BP ele vated more than 20%compared with before operation.Results Analgesia effect on TEA group was better than that of NTEA group(P <0.05),also postoperative BP was signific antly higher than that of before operation in NTEA group(P <0.01),and 18cases need nitroglycerin or s odium nitroprusside therapy;there was no significantly in-crease of BP in TEA group,only 2cases need nitroglycerin therapy.Conclusion TEA had an excellent effect of postop erative pain-relief and blocked sympathetic nerve in patien ts with PDA,so it could reduce postoperative hypertension effectively.

Use of oral ketamine for analgesia during reduction/manipulation of fracture/dislocation in the Emergency Room: An initial experience in a low-resource setting

Background: The use of ketamine for relief of procedure-related pain is limited in our environment. Ketamine, a phencyclidine derivative commonly used for induction and maintenance of anaesthesia, is administered routinely via the intravenous and intramuscular routes. One of the concerns while using ketamine for analgesia via these two routes is that the drug may produce anaesthesia, rather than analgesia alone. Aims and Objectives: We sought to find out if ketamine given via the oral route could be used to provide analgesia during minor orthopaedic procedures in the emergency room. We also wanted to find out if there were side-effects peculiar to the oral route. Methods: A prospective observational pilot study in consecutive patientswith fractures/dislocation in our Emergency Room was recruited into the study. All patients gave informed consent. Reduction of fractures was done 15 minutes following the administration of ketamine 5 mg/kg orally. The patients were observed during and after the procedure and the findings entered into a proforma. The data obtained were analyzed using simple statistical methods and the results presented in a table. The findings are discussed. Results: There were 9 males and 2 females with an age range of 4 yrs to 48 yrs. Pain levels were assessed using verbal rating scales. Seven patients (64%) had severe pain before administration of ketamine while 2 patients (18%) each had mild and moderate pain respectively. Four patients had Colle’s fracture only and 1 patient had a Colle’s fracture with a supracondylar femoral fracture. Two patients had tibial fractures, one patient had a complete knee dislocation, while 2 others had ulnar/radial fractures. One other patient had humeral and tibial fractures. For up to 15 minutes after the procedures all but one patient were pain-free. Five (5) patients (45.5%) were noticed to have drowsiness, 3 patients (27%) were sedated while 2 patients (18%) had no side-effects at all. Five (5) patients (45.5%) reported excellent analgesia while 6 patients (64%) said the intra and post procedure analgesia was very good. Conclusions: Oral ketamine may be useful in providing analgesia for minor procedures in the emergency room. Ketamine when sweetened with a soda drink appears to be palatable with a rapid onset of action and few side effects. Thus ketamine given orally may be a cheaper and more accessible option for effective pain-relief in the emergency room. There is a need to conduct more studies on a larger number of patients.

The effect of postoperative epidural analgesia in women possessing severe gestational hypertension undergoing cesarean delivery

Introduction: The purpose of this study was to examine the clinical usefulness of postoperative epidural analgesia in patients possessing severe gestational hypertension after Cesarean delivery. Methods: We reviewed the obstetric records of 99 patients possessing severe gestational hypertension undergoing singleton Cesarean delivery at ≥ 22 weeks’ gestation. Thirty patients were received continuous epidural analgesia with 0.2% ropivacaine for pain relief after Cesarean delivery with spinal anesthesia, 69 patients were not received epidural analgesia after Cesarean delivery with spinal anesthesia. Results: During the preoperative period, there were no measurable differences in the diastolic blood pressure between the 2 groups (108 vs± 7 vs. 106 mmHg ± 10 mmHg, p = 0.29). The diastolic blood pressure at 2 and 4 hours after Cesarean section in the epidural analgesia group were significantly lower than those in the non-epidural group (2 hours after Cesarean section: 88 vs ± 13 vs. 95 mmHg ± 8 mmHg, p < 0.01;4 hours after Cesarean section: 92 vs ± 15 vs. 102 mmHg ± 9 mmHg, p < 0.01). Conclusions: The current results indicated that the postoperative epidural analgesia can inhibit the rise in diastolic blood pressure in patients possessing severe gestational hypertension after Cesarean delivery.

Objective:To explore the effect of hydromorphone hydrochloride postoperative analgesia on the stress reaction and hemorheology in elderly patients after total hip replacement (THR). Methods:A total of 70 patients who were admitted in our hospital from June, 2015 to June, 2016 for THR were included in the study and randomized into the observation group and the control group with 35 cases in each group. After operation, the patients in the two groups were immediately given patient-controlled analgesia. The patients in the observation group were given hydromorphone hydrochloride, while the patients in the control group were given sufentanil. The peripheral venous blood before operation, 12 and 24 h after operation in the two groups was collected. RIA was used to detect BG and Cor. ELISA was used to detect NE. The peripheral venous blood before operation, 24 and 72 h after operation was collected. The full automatic hematology analyzer was used to detect the plasma PV, BV, and RWBV. Results:Cor and NE levels in the observation group, and BG, Cor, and NE levels in the control group 12 and 24 h after operation were significantly elevated when compared with before operation (P<0.05), but the above indicators at each timing point in the control group were significantly higher than those in the observation group (P<0.05). PV, BV (low-shear, middle-shear, and high-shear), and RWBV (low-shear, middle-shear, and high-shear) levels 24 and 72 h after operation in the two groups were significantly elevated when compared with before operation (P<0.05), but the above indicators at each timing point in the control group were significantly higher than those in the observation group (P<0.05). Conclusions:Application of hydromorphone hydrochloride in the postoperative analgesia in elderly patients with THR has a preferable analgesia effect, can effectively alleviate the postoperative stress reaction, stabilize the hemorheology, and contribute to the rehabilitation.

Effect of hydromorphone hydrochloride postoperative analgesia on the inflammatory cytokines, S-100β, and NSE in elderly patients after total hip replacement

Objective:To explore the effect of hydromorphone hydrochloride postoperative analgesia on the inflammatory cytokines, S-100β, and NSE in elderly patients after total hip replacement (THR).Methods: A total of 100 patients who were admitted in our hospital from January, 2015 to July, 2016 for THR were included in the study and randomized into the observation group and the control group with 50 cases in each group. After operation, the patients in the two groups were immediately given patient-controlled analgesia. The patients in the observation group were given hydromorphone hydrochloride (0.3 mg) + dexamethasone (5 mg) + normal saline (100 mL), while the patients in the control group were given sufentanil (150 μg) + dexamethasone (5 mg) + normal saline (100 mL). The morning fasting peripheral venous blood before operation, 24 h and 3 d after operation in the two groups was collected. ELISA was used to detect the serum CRP, IL-6, and TNF-α, and the plasma S-100β and NSE levels.Results:The serum CRP, TNF-α, and IL-6 levels 24 h and 3 d after operation in the two groups were significantly elevated when compared with before operation, and were reduced 3d after operation. CRP, TNF-α, and IL-6 levels at each timing point after operation in the observation group were significantly lower than those in the control group. The plasma S-100βand NSE levels 24 h and 3 d after operation in the two groups were significantly elevated when compared with before operation, and were reduced 3 d after operation. The plasma S-100β and NSE levels at each timing point after operation in the observation group were significantly lower than those in the control group.Conclusions:Hydromorphone hydrochloride can relieve the postoperative pain in elderly patients with THR, effectively alleviate the inflammatory reaction, reduce the plasma S-100β and NSE levels, and alleviate the cerebral injury, whose pathogenesis remains a further deep study.

Effectiveness and safety of continuous wound infiltrationfor postoperative pain management after open gastrectomy

AIM: To prospectively evaluate the effectiveness and safety of continuous wound infiltration(CWI) for pain management after open gastrectomy. METHODS: Seventy-five adult patients with American Society of Anesthesiologists(ASA) Physical Status Classification System(ASA) grade 1-3 undergoing open gastrectomy were randomized to three groups. Group 1 patients received CWI with 0.3% ropivacaine(group CWI). Group 2 patients received 0.5 mg/m L morphine intravenously by a patient-controlled analgesia pump(PCIA)(group PCIA). Group 3 patients received epidural analgesia(EA) with 0.12% ropivacaine and 20 μg/m L morphine with an infusion at 6-8 m L/h for 48 h(group EA). A standard general anesthetic technique was used for all three groups. Rescue analgesia(2 mg bolus of morphine, intravenous) was given when the visual analogue scale(VAS) score was ≥ 4. The outcomes measured over 48 h after the operation were VAS scores both at rest and during mobilization, total morphine consumption, relative side effects, and basic vital signs. Further results including time to extubation, recovery of bowel function, surgical wound healing,mean length of hospitalization after surgery, and the patient's satisfaction were also recorded.RESULTS: All three groups had similar VAS scores during the first 48 h after surgery. Group CWI and group EA, compared with group PCIA, had lower morphine consumption(P < 0.001), less postoperative nausea and vomiting(1.20 ± 0.41 vs 1.96 ± 0.67, 1.32 ± 0.56 vs 1.96 ± 0.67, respectively, P < 0.001), earlier extubation(16.56 ± 5.24 min vs 19.76 ± 5.75 min, P < 0.05, 15.48 ± 4.59 min vs 19.76 ± 5.75 min, P < 0.01), and earlier recovery of bowel function(2.96 ± 1.17 d vs 3.60 ± 1.04 d, 2.80 ± 1.38 d vs 3.60 ± 1.04 d, respectively, P < 0.05). The mean length of hospitalization after surgery was reduced in groups CWI(8.20 ± 2.58 d vs 10.08 ± 3.15 d, P < 0.05) and EA(7.96 ± 2.30 d vs 10.08 ± 3.15 d, P < 0.01) compared with group PCIA. All three groups had similar patient satisfaction and wound healing, but group PCIA was prone to higher sedation scores when compared with groups CWI and EA, especially during the first 12 h after surgery. Group EA had a lower mean arterial pressure within the first postoperative 12 h compared with the other two groups.CONCLUSION : CWI with ropivacaine yields a satisfactory analgesic effect within the first 48 h after open gastrectomy, with lower morphine consumption and accelerated recovery.

Intranasal ketamine for the treatment of patients with acute pain in the emergency department

BACKGROUND:Pain in the emergency department(ED)is common but undertreated.The objective of this study was to examine the efficacy and safety of intranasal(IN)ketamine used as an analgesic for patients with acute injury with moderate to severe pain.METHODS:This study was a cross sectional,observational study of patients more than 8 years old experiencing moderate to severe pain[visual analog score(VAS)>50 mm].The initial dose of IN ketamine was 0.7 mg/kg with an additional dose of 0.3 mg/kg if VAS was more than 50 mm after 15minutes.Pain scores and vital signs were recorded at 0,15,30 and 60 minutes.Side-effects,sedation level and patient's satisfaction were also recorded.The primary outcome was the number of patients achieving≥20 mm reductions in VAS at 15 minutes.Other secondary outcome measures were median reduction in VAS at 15,30 and 60 minutes,changes of vital signs,adverse events,satisfaction of patients,and need for additional ketamine.RESULTS:Thirty-four patients with a median age of 29.5 years(IQR 17.5–38)were enrolled,and they had an initial median VAS of 80 mm(IQR 67–90).The VAS decreased more than 20 mm at15 minutes in 27(80%)patients.The reduction of VAS from baseline to 40 mm(IQR 20–40),20 mm(IQR 14–20)and 20 mm(IQR 10–20)respectively at 15,30 and 60 minutes(P<0.001).No critical changes of vital signs were noted and adverse effects were mild and transient.CONCLUSION:This study showed that IN ketamine is an analgesic choice for patients with acute injury in moderate to severe pain in an overcrowded and resource limited ED.
