Postoperative Analgesia and Cesarean Section under General Anesthesia: Multicenter Study

Background: Neuraxial anesthesia with intrathecal morphine is the reference technique in cesarean section anesthesia for the management of postoperative analgesia. If there is a contraindication to this, general anesthesia is required. The objective of the study was to evaluate the analgesic effectiveness of 4 analgesic techniques performed during cesarean section under general anesthesia in two centers with different anesthetic practices (North Franche Comté Hospital and Omar Bongo Ondimba Army Training Hospital). Method: This is a retrospective and descriptive study over 2 years, from January 1, 2019 to December 31, 2020. It involved evaluating the analgesic effectiveness and tolerance of morphine in the epidural catheter, wound infiltration, intravenous analgesia and Transversus Abdominous Plane block (TAP block) from the post-anesthesia care unit (PACU) until the 4th post-operative day. Results: Of the 354 cesarean sections performed, 84 (11.14%) received general anesthesia. The average age was 32.27 years. Acute fetal distress was the first indication for cesarean section (45.2%), followed by hemorrhagic placenta previa (10.7%) and prolapse of the cord (8.33%). Morphine in the epidural catheter was the most used (47.6%) followed by parietal infiltration (36.9%), intravenous analgesia (13.1%) and TAP block (2.38%). The analgesic effectiveness was comparable between the techniques from postoperative day 0 to day 4. No difference in side effects. Postoperative morphine consumption was significantly reduced (p = 0.011) in the infiltration (9 mg) and TAP block (9mg) groups compared to the epidural catheter (16 mg) and intravenous analgesia (17 mg). No difference in 02 rehabilitation criteria (ambulation, first bowel movement). No difference in the occurrence of chronic pain. Conclusion: In the event of a cesarean section under general anesthesia, there are effective and well-tolerated alternatives to neuraxial anesthesia, particularly regional anesthesia techniques (nerve blocks), particularly in countries with low availability of morphine.

Effects of combined spinal-epidural anesthesia on anxiety,labor analgesia and motor blocks in women during natural delivery

BACKGROUND The background of this study was analgesia in natural delivery.The combined spinal-epidural anesthesia has obvious analgesic effect on the parturients in natural labor,and combined spinal-epidural anesthesia has been widely used in anesthesia for various diseases.AIM To study the effects of combined spinal-epidural anesthesia on anxiety,labor analgesia,and motor blocks in parturients during natural delivery.METHODS A total of 120 women who gave birth at Changning District Maternal and Child Health Hospital between December 2021 to December 2022 were included;a random number table approach was employed to divide the women into a control group and a joint group,with each group consisting of 60 women.The control group was given epidural anesthesia,while the joint group was given combined spinal-epidural anesthesia.The visual analog scale(VAS)was used to evaluate the degree of maternal pain.Comparisons were made between the two groups’conditions of childbirth and the duration of labor.Apgar scores were used to evaluate the status of the newborns at birth;Self-rating Anxiety Scale(SAS)and General Self-Efficacy Scale(GSES)scores,umbilical artery blood gas analysis indices and stress indices were compared between the two groups;and the frequencies of motor block and postpartum complications were analyzed.RESULTS In comparison to the control group,in the joint group,the VAS scores for the first,second,and third stages of labor were lower(P<0.05).The rates of conversion to cesarean section and postpartum blood loss in the joint group were lower than those in the control group(P<0.05).No significant differences were observed in the Apgar score,the duration of the first stage of labor,or the total duration of labor between the two groups(P>0.05).The second and third stages of labor in the joint group were shorter than those in the control group(P<0.05).When compared to the control group,the postpartum SAS score of the joint group was lower,while the GSES score was greater(P<0.05).Between the control group and the joint group,the differences observed in pH,arterial carbon dioxide partial pressure,arterial oxygen partial pressure,or arterial hydrogen ion concentration were not significant(P>0.05).Nitric oxide,cortisol,and adrenaline levels were lower in the joint group than in the control group(P<0.05).There were no substantial differences in Bromage grade or rate of complications between the two groups(P>0.05).CONCLUSION For parturients during natural delivery,combined spinal-epidural anesthesia can reduce anxiety,provide labor analgesia,shorten labor time,and reduce postoperative stress levels but did not result in a motor block.

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 sphenopalatine ganglion block for effective analgesia during awake fiberoptic nasotracheal intubation: A case report

BACKGROUND Awake fiberoptic nasotracheal intubation(AFNI)is the preferred airway ma-nagement strategy for patients with difficult airways.However,this procedure can cause significant physical and psychological distress.This case report explores the application of a sphenopalatine ganglion(SPG)block as an alternative anal-gesic modality to mitigate the discomfort associated with AFNI.CASE SUMMARY A 63-year-old female with a history of right maxillary osteosarcoma underwent craniotomy for a suspected malignant brain lesion.The patient’s medical history included prior surgery,chemotherapy,and radiation therapy,resulting in signi-ficant jaw impairment and limited neck mobility.Considering the anticipated air-way challenges,AFNI was planned.A SPG block was performed under real-time ultrasound guidance,providing effective analgesia during nasotracheal intuba-tion.CONCLUSION The SPG block represents a promising analgesic approach in AFNI,offering po-tential benefits in alleviating pain involving the nasal and nasopharyngeal regions as well as improving patient cooperation.

Regional anesthesia in a patient with primary ciliary dyskinesia:A case report

BACKGROUND Primary ciliary dyskinesia(PCD)is an inherited autosomal-recessive disorder of impaired mucociliary clearance characterized by chronic respiratory diseases,otolaryngological diseases,central nervous system abnormalities,reproductive system abnormalities,and cardiac function abnormalities.General anesthesia in these patients is associated with a higher incidence of respiratory complications than in patients without the disease.CASE SUMMARY A 16-year-old male patient was referred to the emergency room complaining of right ankle pain due to distal tibiofibular fracture.Three years prior,he had been diagnosed with PCD.At that time,he had experienced several episodes of pneumonia,sinusitis,and chronic middle ear infections,for which he underwent surgical interventions.At the current admission,he presented with cough and sputum but no other respiratory symptoms.A chest computed tomography scan revealed centrilobular ground-glass opacities in both lower lobes and a calcified nodule in the left lower lobe.For the surgical procedure and postoperative pain management,combined spinal-epidural anesthesia was employed.The patient’s postoperative pain score was measured by the numerical rating scale(NRS).On the day of surgery,his NRS was 5 points.By the second postoperative day,the NRS score had decreased to 2–3 points.The epidural catheter was removed on the fourth day following the operation.The patient was subsequently discharged no respiratory complications.CONCLUSION We performed combined spinal-epidural anesthesia in a patient with PCD.The patient experienced no additional respiratory complications and was discharged with a low NRS score for pain.

Comparisons of different methods of anesthesia and analgesia on the levels of glycometabolism rate-limiting enzymes in erythrocytes and plasma glucose and stress hormones in patients undergoing esophagus surgery

Objective： To compare the effects of different methods of anesthesia and analgesia on the activities of phosphofructokinase（PFK）, glucose-6-phosphate dehydrogenase（G-6PD） and aldose reductase（AR） in erythrocytes and levels of plasma glucose and stress hormones in patients undergoing esophagus surgery. Methods： Sixty-two patients scheduled for esophagus surgery were randomly divided into three groups： group Ⅰ （n = 20） receiving only general anesthesia（GA） followed by intravenous patient controlled analgesia（PCA） with fentanyl 15 μg/kg. The other two groups receiving both general anesthesia combined with thoracic epidural anesthesia （GEA） and either intravenous PCA with fentanyl 15 μg/kg （group Ⅱ, n = 21） or thoracic epidural analgesia（TEA） with 0.125% ropivacaine and 0.0002% fentanyl mixture（group Ⅲ, n = 21） after the operation. Venous blood samples were collected for measurements of PFK, G-rPD and AR activities in erythrocytes and plasma glucose, cortisol, epinephrine and norepinephrine before induction （T1）, 60 min following the incision （T2）, 60 min（T3） after operation, on the lst（T4） and 2nd postoperative day（T5）. Results： The activities of PFK decreased（P 〈 0.01 or P = 0.004） and the activities of G-6PD and AR increased（P 〈 0.01） in groups Ⅰ and Ⅱ on T4 compared with those on T1 Between the two groups, the activities of these enzymes in group Ⅱ changed less than those of group Ⅰ （P 〈 0.01 or P 〈 0.05）. These enzymes activities changed slightly in group Ⅲ on T4（P 〉 0.05）. There were significant differences between group Ⅲand the other two groups（P 〈 0.0l or P 〈 0.05）. The levels of plasma glucose increased significantly on T2（P 〈 0.01）, reached peak values on Ta（P 〈 0.01） and fell on T5 in the three groups. Compared to those of groups Ⅰ and Ⅱ, the values of plasma glucose in group Ⅲwere lower on T4 and T5（P 〈 0.05 or P 〈 0.01）. The cortisol concentration in each group increased significantly at T2（P 〈 0.01 or P 〈 0.05）, and remained elevated on T5（P 〈 0.01 or P 〈 0.05）, while on T2 and T3 the cortisol levels＇ of group I were higher than that of groups Ⅱand Ⅲ （P 〈 0.05）. The levels of group Ⅲ were lower than those of the other groups on T4 and T5（P 〈 0.01 or P 〈 0.05）. The levels of epinephrine and norepinephrine were also significantly higher in group Ⅰ than those of the other two groups on T2（P 〈 0.01 or P 〈 0.05）, and their levels in group Ⅰ and Ⅱ were higher than that of group Ⅲ on T4. The patients of the three groups obtained satisfactory pain relief, with all Vidual Analogue Scale（VAS） scores less than 3. VAS scores of group I were much greater 4h after operation. Group m VAS scores were the lowest 24h after operation. However, the number of times patients pressed the bolus switch was higher in group Ⅱ （P 〈 0.01）. Conclusion： Compared with GA and intravenous PCA, general anesthesia combined with thoracic epidural anesthesia and analgesia obtain better pain relief and could markedly alleviate the stress response and improve these erythrocyte glucose metabolism changes after esophagus surgery.

Caudal Anesthesia: Experience in the Post-Operative Analgesia in Pediatric Ambulatory Surgery at the University Hospital of Treichville

Introduction: The caudal anesthesia is used by many authors for postoperative analgesia. The purpose of this study was to report our experience in the practice of caudal block as post operative analgesia method in ambulatory surgery in a context of limited technical equipment. Patients and Method: Over a period of 5 months, a prospective study was conducted on 39 children aged 3 to 5 years weighing on average 15.12 kg. Children classified ASA I and II were selected. After premedication with midazolam (0.3 mg/kg) by intra rectal route, the inhalation induction was made with sevoflurane 8%, conveyed by fresh gas (50% O2 and 50% air). The caudal block was obtained with the levobupivacaine 0.25% at a dose of 1 ml/kg. The hemodynamic parameters (systolic and diastolic blood pressure, heart rates) and respiratory parameters (respiratory frequency) pre-, per- and post-operative were measured. Post-operative pain was assessed with the Objective Pain Scale (OPS). The date of first use of analgesia was noted. The adverse effects of caudal block (meningitis, respiratory disorders, acute urinary retention, cardiac disorders) have been assessed. Results: The average duration of the procedure was 55.2 minutes. The use of analgesia was made 4 hours after skin closure, when the OPS Broadmann score was greater than 3. An agitation was observed in 6 children. Haemodynamic parameters have not significantly varied from the pre- to the post-operative. No infectious complications or intolerance to local anesthetics were observed. Allthe children were able to drink 4 hours after the end of the intervention and issued their first urine later than 3 hours after surgery. Conclusion: This type of anesthesia has been found very suitable for ambulatory surgery of the child, and is always helpful. It assured a post operative analgesia of good quality, and a reduction in consumption of morphine intraoperatively.

Comparative Study between General Anesthesia versus General Anesthesia Combined with Thoracic Epidural Analgesia on Cytokine Response in Laparoscopic Cholecystectomy Patients

Background and Objectives: The main benefits of laparoscopic surgery in comparison to open surgery involve the rapid discharge from recovery room, decreased postoperative hospital stays, reduced postoperative discomfort, easier getting back to work and faster return to ordinary daily life as well as cosmetic surgical wounds. The anesthesia type has an essential role in attenuation of the surgical stress and achievement of these advantages. We aimed to determine the outcome of giving general anesthesia in conjunction with thoracic epidural analgesia (TEA) compared to general anesthesia alone on stress response to surgery and anesthesia by investigating cytokine reaction (interleukin 6 and 8 levels), hemodynamic changes (BP, HR, RR, SPO2), and Visual Analogue Scale (VAS) scores postoperatively in patients subjected for laparoscopic cholecystectomy. Methods: This study included 40 patients aged 20 - 60 years old with American Society of Anesthesiologists physical status (ASA) I and II. They were planned for laparoscopic cholecystectomy at Aswan University Hospital from April 2017 to March 2018. They were randomly allocated into two groups. Group A (n. 20) received general anesthesia only and Group B (n. 20) received general anesthesia in conjunction with thoracic epidural analgesia using fentanyl and bupivacaine in the epidural catheter. Chi-square was applied to differentiate categorical variables, whereas comparison between continuous variables was done by using t-test. Two-tailed p < 0.05 was estimated as statistically significant. Results: As regards IL-6 and IL-8 post-operative there is significant difference (p < 0.05) between two groups during 2nd and 4th hr and 24th hr postoperative, with significantly increased postoperative levels of IL-6 and IL-8 in comparison to their preoperative baseline values. The largest increase in IL6 & IL8 levels was in group A (GA group). VAS score showed significant lower values in TEA group in comparison to GA group. No significant difference between groups as regard intraoperative and postoperative hemodynamic changes. Conclusion: Regional techniques including TEA attenuate and decrease cytokine reaction secondary to surgery which decreases inflammatory process and improves patient outcome and reduces pain score postoperatively.

Efficacy of low-dose fentanyl and ropivacaine combined spinal-epidural anesthesia for labor analgesia

Objective: To study the efficacy of low-dose fentanyl and ropivacaine combined spinal-epidural anesthesia for labor analgesia. Methods: Puerperae who underwent vaginal delivery under combined spinal-epidural anesthesia for labor analgesia in Lincheng People's Hospital between June 2014 and March 2017 were selected and randomly divided into three groups, group A received 15 μg small-dose fentanyl and ropivacaine combined spinal-epidural anesthesia for labor analgesia, group B received 25 μg large-dose fentanyl and ropivacaine combined spinal-epidural anesthesia for labor analgesia, and group C received ropivacaine epidural anesthesia alone for labor analgesia. During delivery, the serum in the second stage of labor was collected to determine the contents of pain transmitters, inflammatory cytokines and stress response indexes. Results: During delivery, serum SP, 5-HT, DA, NE, DYN, TNF-α, IL-1β, IL-6, IL-10, PGE2, Cor, C-P, MDA and AOPP contents of group A and group B were lower than those of group C and serum SP, 5-HT, DA, NE, DYN, TNF-α, IL-1β, IL-6, IL-10, PGE2, Cor, C-P, MDA and AOPP contents of group A were not significantly different from those of group B. Conclusion: 15 μg small-dose fentanyl and ropivacaine combined spinal-epidural anesthesia for labor analgesia is with exact efficacy and good safety.

Research Status of Preemptive Analgesia and its Application in Clinical Anesthesia

The most effective treatment for postoperative pain is to reduce it by preventing or reducing the sensitivity and sensory disturbance on the central nervous system during the operation,prolonging the pain-relief time and reducing the use of analgesics.Preemptive analgesia refers to the intervention of central neuraxis sensitization and peripheral sensitization to prevent the expansion and spread of pain,so as to achieve postoperative pain-relief.In postoperative patient-controlled analgesia,preemptive analgesia has become a common treatment method for anesthesiologists.However,the clinical specifications for advanced analgesia are still lacking.Based on this,this paper reviews the use of advanced analgesia drugs and their clinical applications.

Clinical study of acupuncture combined with surface anesthesia using proparacaine in geriatric cataract phacoemulsification

BACKGROUND During anesthesia administration for cataract surgery,low pH of proparacaine may induce pain or complications such as corneal damage and poor wound healing,with the use of additional drops intraoperatively increasing the risk of complications.Accordingly,there is a clinical need for adjuncts to local anesthesia needs to improve the efficiency of anesthesia and reduce the required amount of intraoperative proparacaine.AIM To identify a method of anesthesia for geriatric cataract phacoemulsification that provides more efficient analgesia and improves clinical efficacy.METHODS A total of 130 geriatric patients with cataracts who attended Hebei Eye Hospital from December 2020 to December 2022 were included in the present study.Patients were divided into the proparacaine surface anesthesia(SA)group(65 cases)and the compound acupuncture-medicine anesthesia group(CAMA group,65 cases).Patients in the CAMA group were provided acupuncture analgesia in addition to SA.Preoperative anxiety[Self-Rating Anxiety Scale(SAS)score and state anxiety inventory(SAI)score],intraoperative stress,vital signs,analgesia,and cooperation,as well as postoperative adverse events,were compared between groups.RESULTS More marked reductions in anxiety were observed among patients in the CAMA group,with corresponding reductions in SAS and SAI scores.During the operation,no change in the secretion of E,NE,or Cor group compared to the preoperative period was observed in the CAMA,which was markedly lower than that in the SA group.Heart rate,blood pressure,and respiratory rate were more stable intraoperatively in the CAMA group.In addition,the incidence of intraoperative pain and the number of additional doses of anesthesia required in the CAMA group were markedly lower than in the SA group.Accordingly,patients in the CAMA group were able to avoid eye movements and eyelid closing leading to greater cooperation with surgeons during surgery.Furthermore,marked reductions in intraoperative adverse effects were observed in the CAMA group,indicating greater overall safety.CONCLUSION Proparacaine SA combined with acupuncture as an analgesic provides improved analgesia with greater safety compared to surface anesthesia with proparacaine during geriatric cataract phacoemulsification.

Postoperative Analgesia for Abdominal Laparoscopic Surgery: Tap Block vs Peri-Orificial Infiltrations

Introduction/Purpose: The “transverse abdominal plane block” or TAP block was described by Rafi in 2001. It describes an approach to the neurofascial plane of the transverse abdominal muscle via the Jean-Louis Petit triangle and provides analgesia of the entire homolateral hemi abdomen. The aim of our study was to compare post-operative analgesia and post-operative morphine requirements between transverse abdominal plane block (TAP) and peri-orificial infiltration during laparoscopic abdominal surgery. Material and method: Prospective, randomized study conducted over a 2-year period. The study was conducted in the operating theatre of the Saint Louis Regional Hospital in Senegal. All adult patients undergoing laparoscopic abdominal surgery were included. Clinical aspects, pain scales and morphine consumption were analyzed. Results: A total of 60 patients were enrolled: 30 patients in the TAP group and 30 patients in the infiltration group. The average age was 32.9 years. The indications for laparoscopy were acute appendicitis in 50% of cases, gallbladder stones in 16% and inguinal hernia in 8%. For the TAP group, the mean numerical pain scale was 3.9 at 6 hours post-operatively and 2.1 at 24 hours post-operatively. For the infiltration group, the mean numerical pain scale was 4.3 at 6 hours post-op and 3 at 24 hours post-op. Morphine consumption at 6 hours post-op was on average 0.4 mg/patient for the TAP group and 0.9 mg/patient for the infiltration group. Discussion/conclusion: Analgesia provided by ultrasound-guided TAP block for laparoscopic abdominal surgery appears to be identical to periorificial infiltration. However, the simplicity and reproducibility of ultrasound-guided TAP block gives it a definite advantage.

目的探讨纳布啡用于硬脊膜穿破硬膜外阻滞分娩镇痛的有效性及安全性。方法选择经阴试产的足月单胎初产妇319例,按使用药物不同分为舒芬太尼硬脊膜穿破硬膜外阻滞组(A组)160例,纳布啡硬脊膜穿破硬膜外阻滞组(B组)159例。两组均采用硬脊膜穿破硬膜外阻滞分娩镇痛法,置入硬膜外导管后,注入1.5%利多卡因3 mL试验量,然后A组注入0.5 mg/L舒芬太尼复合1 mg/L罗哌卡因混合液,B组注入0.3 g/L纳布啡复合1 mg/L罗哌卡因混合液,均6~15 mL为首次量,30 min后两组均连接电子镇痛泵,分别使用舒芬太尼和纳布啡进行自控硬膜外镇痛。收集两组患者的如下指标:镇痛起效时间、首次自控按压镇痛(PCA)时间、PCA有效按压次数、罗哌卡因用量;镇痛前(T0)、镇痛后30 min(T1)、宫口开全(T2)与用力分娩(T3)时疼痛视觉模拟(VAS)评分及Ramsay镇静评分;产妇发热、恶心呕吐、皮肤瘙痒、术后头痛发生等不良反应情况以及胎儿胎心减速发生率、新生儿1 min Apgar评分≤7分发生率、脐动脉血气分析,新生儿神经与适应能力评分。结果与A组比较,B组恶心呕吐、皮肤瘙痒、胎心减速及新生儿1 min Apgar评分≤7分的发生率显著降低(χ^(2)=4.159~5.628,P<0.05),PCA有效按压次数、罗哌卡因用量显著增加(χ^(2)=8.594、6.363,P<0.05),T2及T3产妇VAS评分明显升高(F=45.314、26.717,P<0.05),其他观察指标两组间比较差异无统计学意义(P>0.05)。结论纳布啡用于硬脊膜穿破硬膜外阻滞分娩镇痛与舒芬太尼相比第一产程镇痛效果类似,第二产程效果较差,但可降低产妇镇痛相关不良反应发生率,对新生儿具有较高的安全性。
