Analysis of factors impacting postoperative pain and quality of life in patients with mixed hemorrhoids:A retrospective study

BACKGROUND Hemorrhoids are among the most common and frequently encountered chronic anorectal diseases in anorectal surgery.They are venous clusters formed by con-gestion,expansion,and flexion of the venous plexus in the lower part of the rec-tum.Mixed hemorrhoids bleed easily and recurrently,and this can result in severe anemia.Hence,they may have a negative effect on the health of the patient and surgical treatment is required.Milligan-Morgan hemorrhoidectomy has been widely used since 1937 for the treatment of grade III and IV hemorrhoids.How-ever,most patients experience different degrees of postoperative pain that may cause anxiety.with mixed hemorrhoids post-surgery.METHODS The clinical data of patients with mixed hemorrhoids who underwent Milligan-Morgan hemorrhoidectomy were collected retrospectively.The basic character-istics of the enrolled patients with mixed hemorrhoids were recorded,and based on the Goligher clinical grading system,the hemorrhoids were classified as grades III or IV.The endpoint of this study was the disappearance of pain in all patients.Quantitative data were presented as mean±SD,such as age,pain score,and QoL score.Student’s t-test was used to compare the groups.RESULTS A total of 164 patients were enrolled.The distribution of the visual analog scale pain scores of all patients at 3,7,14 and 28 d after surgery showed that post-surgery pain was significantly reduced with the passage of time.Fourteen days after the operation,the pain had completely disappeared in some patients.Twenty-eight days after the surgery,none of the patients experienced any pain.Comparing the World Health Or-ganization Quality of Life-BREF self-reporting questionnaire scores of patients between 14 and 28 d after surgery,we observed that the quality-of-life scores of the patients post-surgery had significantly improved.There were six items that were compared at 14-and 28-d post-surgery.The mean QoL score 28 d after surgery(4.79±0.46)was higher than that at 14 d post-surgery(3.79±0.57).The mean health condition score 28 d after surgery(4.80±0.41)was also higher than that at 14 d post-surgery(4.01±0.62).The mean physical health score 28 d after surgery(32.10±2.96)was significantly higher than that at 14 d post-surgery(23.41±2.85).The mean psychological health score 28 d after surgery(27.22±1.62)was significantly higher than that at 14 d post-surgery(21.37±1.70).The mean social relations score 28 d after surgery(12.21±1.59)was significantly higher than that at 14 d post-surgery(6.32±1.66).The mean surrounding environment score 28 d after surgery(37.13±2.88)was significantly higher than that at 14 d post-surgery(28.42±2.86).The differences in quality-of-life scores at day 14 and day 28 post-surgery were ob-served to be statistically significant(P<0.001).CONCLUSION Milligan-Morgan hemorrhoidectomy can significantly improve the postoperative QoL of patients.Age,sex,and the number of surgical resections were important factors influencing Milligan-Morgan hemorrhoidectomy.

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.

Analysis of the Effects of Local Injection of Epinephrine and Lidocaine on Postoperative Pain and Bleeding in Children Undergoing Tonsillectomy

Objective:To explore the effects of local injection of epinephrine and lidocaine on postoperative pain and bleeding in children undergoing tonsillectomy.Methods:Sixty-eight children who underwent a tonsillectomy in our hospital from March 2019 to October 2020 were selected.The children were randomly divided into two groups of 34 cases each.The observation group received local anesthetic injections of lidocaine and the control group received local anesthetic injections of epinephrine.The postoperative pain,operation time,blood pressure changes,and intraoperative blood loss of the two groups of children were observed and analyzed.Results:The postoperative pain,operation time,and intraoperative blood loss scores of the children in the observation group were 4.36±0.69,0.36±0.09,and 39.36±1.78 respectively,which were significantly better than those of the children in the control group(P<0.05)at 5.36±0.77,0.79±0.05,and 45.36±1.56,respectively.The systolic blood pressure and diastolic blood pressure of the observation group 3 minutes before surgery and 180 minutes after surgery were no different from those of the control group(P>0.05).Conclusion:Local injection of epinephrine and lidocaine effectively relieved postoperative pain and reduced bleeding in children undergoing tonsillectomy as compared to epinephrine alone.

Clinical Observation of Chinese Medicinal Prescriptions for Swelling and Pain in The Postoperative Treatment of Mixed Hemorrhoids

Objective:To observe the clinical effect of traditional Chinese medicine(TCM)on reducing swelling and pain in patients with mixed hemorrhoids.Methods:Sixty patients with mixed hemorrhoids who were admitted to the Hospital of Traditional Chinese Medicine of Qiqihar from January 2023 to January 2024 were selected and divided into two groups.The treatment group(n=30)was treated with mixed hemorrhoid ligation combined with traditional Chinese swelling and pain medicine,and the control group(n=30)was only treated with mixed hemorrhoid ligation.The pain level,edema score,and prognosis of the two groups after the intervention were analyzed.The clinical efficacy was used as the evaluation criterion to compare the clinical effects of different treatment options.Results:After the treatment,the pain score,edema score,and prognostic wound score of the treatment group were all lower than those of the control group(P 0.05).The total clinical effectiveness of the treatment group(100%)was higher than that of the control group(76.67%),(χ^(2)=4.2857,P<0.05).Conclusion:The application of traditional Chinese swelling and pain medicine in treating patients with mixed hemorrhoids effectively reduced the patient’s pain,reduced the degree of wound edema,promoted wound healing,and improved the patient’s prognosis.The curative effect was significant and had a positive impact.

Foot and ankle surgery:Tourniquet placement site to cause as little postoperative pain as possible

There is controversy in the literature on where to place the tourniquet(thigh,calf,ankle)for foot and ankle surgery.While some authors prefer the ankle tourniquet to the calf tourniquet,others state that the surgeon can decide between using the thigh tourniquet or the ankle tourniquet,since there was no difference in postoperative pain between them.Where to place the tourniquet during foot and ankle surgery to cause the least possible postoperative pain to the patient as a result of the tourniquet is a common question in clinical practice.The reality is that,unfortunately,there is no consensus on this issue.Perhaps the only possible way to answer this question would be to conduct a comparative study with sufficient statistical power to reach scientifically sound conclusions.It does not seem easy to carry out such a study,but it would be important to be able to answer the question posed in the title of this Editorial once and for all.

Neuroanatomical Basis of Postoperative Pain and Assessment of Its Management in a Series of Patients Undergoing Caesarean Sections

Introduction: In recent decades, the cost of postoperative pain has been the subject of many studies based on protocols developed by scientific societies for its assessment and optimization. At the Regional Hospital of Saint-Louis (Senegal), several protocols have been developed for pain management, but no study has focused on the assessment of postoperative pain management specifically. We therefore initiated this work, the objectives of which were to remind the neuroanatomical and neurophysiological bases of postoperative pain, and to analyze the assessment and management of this pain in patients who have undergone a caesarean section. Materials and methods: This was a prospective and descriptive study, which took place in the gynecology-obstetrics department, over a period from January 2019 to July 2020. All patients who gave birth by cesarean section were included. The data was collected from a survey sheet written for this purpose. For each of the patients, the information was taken every day throughout the duration of postoperative hospitalization. Results: It appears from our work that after a cesarean section, the pain felt evolves on the first postoperative days with a peak during the second day. As in the data reported in the literature, there does not seem to be a difference in terms of pain intensity and analgesia dosage between scheduled and emergency caesarean sections. However, young age and female gender—for other types of surgeries—are risk factors associated with high postoperative pain scores. This trend is probably related to the low pain experience of tested patients. Our initial hypothesis was that acute post-operative pain after caesarean sections could be linked to defects in the perception and processing of pain by caregivers. Indeed, we have shown that awareness-raising, information, and training actions have made it possible to significantly improve the management of pain after a cesarean section. Conclusion: After a cesarean section the pain is intense, especially when the effects of the morphine wear off. However, in our context where morphine and its derivatives are only slightly used, the post-operative pain is maximal rapidly. This pain therefore needs to be researched and treated appropriately. After a campaign to raise awareness among healthcare personnel, it is possible to significantly improve the systematic administration of analgesics.

Postoperative pain assessment and management among nurses in selected hospitals in Benin City,Edo State,Nigeria

Objective:This study was designed to determine the nurse assessment of postoperative pain and its management in selected hospitals,Benin City,Edo State,Nigeria.Materials and Methods:A descriptive cross-sectional survey was adopted.The target population consist of 222 purposely nurses who are in the cadre of nursing officer II to chief nursing officer who works in the various surgical wards/units of the selected health facilities.The data were collected from the participants using the pretested structured questionnaire developed by the researcher.Results:Results showed that 66.2%of nurses had a poor level of knowledge on postoperative pain assessment.The McGill Pain Questionnaire was the most used pain assessment tool with a mean score of 2.84 whereas the Dallas Pain Questionnaire was the least used with a mean score of 1.90.“Providing clean,calm,and well-ventilated ward environment”(3.69±0.61)was the most used nonpharmacological method for postoperative pain management,followed by“distraction,relaxation,and guided imagery”(3.52±0.50),“dressing,bandage,splint,and reinforce wound sites postoperatively”(3.39±0.54),and“early ambulation/exercise”(3.20±0.62).The most used pharmacological interventions were“acetaminophen”(3.63±0.55),“topical anesthetic”(2.92±0.62),“nonselective nonsteroidal anti-inflammatory drugs”(2.87±0.43),and“mixed opioid agonist-antagonist”(2.56±0.56).Conclusion:There is a poor level of knowledge on postoperative pain assessment among nurses in this study setting.It is,therefore,pertinent for hospitals to organize continuous in-service training for postoperative pain assessment and management,especially on nonpharmacological approaches among nurses.

Early Application Study of Intravenous Pain Pump Combined with Parecoxib Injection in Relieving Pain in Patients after Thoracoscopy

Objective: To explore the clinical effectiveness of combined use of intravenous pain pump with Parecoxib injection in alleviating pain in patients during the early postoperative period after thoracoscopic surgery. Methods: Eighty patients who underwent thoracoscopic surgery in a tertiary hospital were selected as the study subjects and randomly divided into two groups, with 40 patients in each group. The control group received routine postoperative treatment with intravenous pain pump, while the experimental group received Parecoxib in addition to the standard postoperative pain pump treatment. Visual Analog Scale (VAS) pain scores were used to evaluate postoperative pain relief in both groups, along with adverse reactions, postoperative complications, and patient satisfaction with pain relief. Results: Patients who received Parecoxib injection in addition to the routine use of intravenous pain pump had VAS pain scores lower than 3 points at 6 h, 12 h, 24 h, and 36 h postoperatively compared to those in the control group. The incidence of postoperative lung collapse, pleural effusion, and pulmonary infections was also significantly lower in the experimental group. The differences between the two groups were statistically significant (P Conclusion: Early combined use of Parecoxib injection in the early postoperative period after thoracoscopic surgery has shown good clinical efficacy. It can reduce the level of pain in patients, promote effective coughing and expectoration, facilitate early mobilization of patients, improve patient compliance, reduce complications, shorten hospital stay, and expedite patient recovery. Therefore, it is worth promoting the widespread clinical application of Parecoxib injection in this setting.

Pain threshold, anxiety and other factors affect intensity of postoperative pain in gastric cancer patients: A prospective cohort study

Objective: This prospective cohort study explored factors related to postoperative pain in gastric cancer patients.Methods: A total of 236 patients who underwent gastrectomy were enrolled. All patients enrolled in the study completed the Hospital Anxiety and Depression Scale(HADS) questionnaire and Life Orientation Test-Revised(LOT-R) questionnaire on the day before surgery. Heat pain threshold(HPT), cold pain threshold(CPT) and pressure pain threshold(PPT) were measured for all patients one day prior to surgery and demographic details were collected. All patients were connected to a patient-controlled intravenous analgesia(PCIA) pump at the end of the surgery. The occurrence of postoperative pain was used as a dependent variable, and multivariate logistic regression analyses were conducted to screen for factors affecting postoperative pain.Results: In total, 83 patients(35.2%) had postoperative pain. Body mass index(BMI) ≥28 kg/m^(2) [odds ratio(OR): 2.67;95% confidence interval(95% CI): 1.07-6.67], total gastrectomy(OR: 2.64;95% CI: 1.42-4.91),preoperative anxiety score ≥8(OR: 2.37;95% CI: 1.12-5.02), heat pain threshold ≤4.9 s(OR: 2.14;95% CI:1.06-4.32), pressure pain threshold ≤4 g(OR: 2.05;95% CI: 1.05-4.03), and female gender(OR: 1.99;95% CI:1.04-3.83) were risk factors for postoperative pain.Conclusions: Obesity, wide range of gastrectomy, high preoperative anxiety, low HPT and PPT, and female gender are associated with increased risk for postoperative pain.

Diabetic Patients Develop Greater Intensity of Postoperative Pain than Non-Diabetics after Open Cholecystectomy: A Pilot Study

Background: Pre-clinical and clinical studies have shown that inflammatory pain intensity is increased under diabetes condition. Open cholecystectomy (OC) is a surgical procedure with predictable postoperative pain. However, the comparison of postoperative pain due to open cholecystectomy in diabetic and non-diabetic patients remains unknown. The research question to answer was whether diabetic patients undergoing OC development greater intensity of postoperative pain than non-diabetic patients. Methods: The study was conducted between June 2016 and February 2018 at the Regional Hospital of High Specialty “Dr. Juan Graham Casasús” of Villahermosa, Tabasco, Mexico. Seventy patients in two groups of 35 patients each scheduled for OC under general anesthesia were studied. Pain was assessed using the 11-point numerical rating scale (NRS). The primary endpoint was to know NRS pain scores after awaking of general anesthesia. Secondary outcomes included the time of onset of pain and comparing NRS scores between diabetic and non-diabetic patients undergoing OC. Results: Diabetic patients reported significantly greater intensity pain than non-diabetic patients. The mean overall pain score in the diabetic and non-diabetic patients was 7.2 ± 0.3 and 5.3 ± 0.3 (P = 0.0002), respectively. Furthermore, 60% of diabetic patients had severe pain (NRS ≥ 8) compared to 20% of non-diabetics (P = 0.006). The time to onset postoperative pain was about 35 minutes in both groups (P = 0.876). Conclusions: Diabetic patients undergoing OC have greater intensity postoperative pain and also more frequency of patients with severe pain scores compared with non-diabetic patients. Therefore, analgesic treatment in those patients should consider this point in order to provide a satisfactory postoperative analgesia.

Comparison of external treatment of Acupuncture and moxibustion and intervention of Chinese and Western Medicine on postoperative pain of hemorrhoids:A systematic review and meta-analysis

Background To evaluate the clinical efficacy and safety of acupuncture and moxibustion in the treatment of postoperative pain of hemorrhoids compared with traditional Chinese medicine and western medicine.Methods CNKI,PubMed,Cochrane Library,Science Direct,Wan Fang,VIP,CBM,WOS,Bailian Yun Library and other databases were systematically retrieved from January 1,2017 to October 31,2022 for clinical randomized controlled trials of acupuncture versus traditional Chinese medicine and Western medicine for postoperative pain in hemorrhoids.The two evaluators independently retrieved,sifted through literature and extracted data for inclusion in a randomized controlled trial of acupuncture for the treatment of hemorrhoid pain that matched the study.Literature quality assessment was performed using RevMan5.4 for meta-analysis.Results A total of 540 related literature articles were retrieved,of which 139 were from CNKI,104 from Wan Fang,26 from VIP,7 from PubMed,9 from Cochrane Library,35 from WOS,173 from CMB,1 from Science Direct and 46 from the Bailian Yun Library,Screening resulted in inclusion of 10 RCTs including 870 patients.Meta analysis showed no statistically significant difference between the degree of pain in 2 hours[MD=-0.01,95%CI(-0.23,0.24),P=0.95].And it showed that the total effective rate of the two groups was[RR=1.14,95%CI(1.06,1.24),P=0.001],intervention for 2 days pain degree was[MD=0.41,95%CI(0.13,0.69),P=0.004],the length of hospital stay was[SMD=1.10,95%CI(0.73,1.48),P<0.00001],the incidence of adverse reaction was[RR=0.15,95%CI(0.03,0.79),P=0.03],the difference was statistically significant(P<0.05).Conclusion Drug treatment is effective quickly,analgesia effect is better than acupuncture in early treatment,but the effect is not lasting.Acupuncture treatment is slow to start but the effects of acupuncture will gradually become apparent at a later stage.However,due to the poor quality of collection,multicenter,large sample size and double-blind randomized controlled trials are still needed.

Effects of Electroacupuncture on Pain Threshold and Prostaglandin E2 in Spinal Cord in Postoperative Pain Rat

Objective:Electroacupuncture(EA)is good at post-surgical pain.But point selection method in treating incision-induced pain remains a major clinical challenge.We reasoned that different acupoints may work though adjusting prostaglandin E2 in spinal cord.We wish to explore the analgesic mechanism of electroacupuncture on plantar incision pain rats and provide more therapeutic ideas for acupuncture analgesia.Methods:A total of 50 male rats were randomly divided into a sham operation group,a model group,an EA 1,EA 2 and a drug group(n=10,each).A rat model of left plantar incision pain was established.The rats in EA1 group was needled at ipsilateral Yanglingquan(GB34)and Taixi(KI3).The rats in EA2 group was needled at ipsilateral Quchi(LI11)and Hegu(LI4).EA stimulation(2/100 Hz,1-2-3 mA)was administered 30 minutes immediately after operation.The rats in drug group were fed with Fenbid by gavage 20 minutes before incision(30 mg/kg,p.o.).The hot plate pain detector was used to measure the thermal pain threshold(TPT)before and 24 hours after operation Prostaglandin E2 content of spinal cord was detected by enzyme-linked immunosorbent assay(ELISA)at 1 and 24 hours after operation.Results:Compared with sham operation group,the TPT in model group decreased 41%.Compared with the model group,the TPT increased 56%in EA1,29%in EA2,190%in drug group(P>0.05).At 1 h after operation,compared with the sham operation group,PGE_2 in model group increased 15%.Compared with the model group,PGE_2 in drug group decreased 5%.At 24 hours after operation,compared with sham operation group,PGE_2 in model group increased 9%.Compared with model group,it decreased 4%in EA 1 group,8%in drug group and increased 3%in EA2 group.Conclusion:Both the drug and the electroacupuncture can adjust the 24-hour pain threshold and PGE_2 in spinal cord.The curative effects of the drug are better than that of electroacupuncture.The proximal point is better than that of the distal point.Electroacupuncture can treat postoperative pain by regulating PGE_2 in spinal cord.

Effect of local wound infiltration with ropivacaine on postoperative pain relief and stress response reduction after open hepatectomy

AIM To prospectively evaluate the effect of local wound infiltration with ropivacaine on postoperative pain relief and stress response reduction after open hepatectomy.METHODS A total of 56 patients undergoing open hepatectomy were randomly divided into two groups:a ropivacaine group(wound infiltration with ropivacaine solution)and a control group(infiltration with isotonic saline solution).A visual analog scale(VAS)at rest and on movement was used to measure postoperative pain for the first 48 h after surgery.Mean arterial pressure(MAP),heart rate(HR),time to bowel recovery,length of hospitalization after surgery,cumulative sufentanil consumption,and incidence of nausea and vomiting were compared between the two groups.Surgical stress hormones(epinephrine,norepinephrine,and cortisol)were detected using enzyme-linked immunosorbent assay,and the results were compared. RESULTS VAS scores both at rest and on movement at 24 h and48 h were similar between the two groups.Significantly lower VAS scores were detected at 0,6,and 12 h in the ropivacaine group compared with the control group(P<0.05 for all).MAP was significantly lower at 6,12,and 24 h(P<0.05 for all);HR was significantly lower at 0,6,12,and 24 h(P<0.05 for all);time to bowel recovery and length of hospitalization after surgery(P<0.05 for both)were significantly shortened;and cumulative sufentanil consumption was significantly lower at 6,12,24,and 36 h(P<0.05 for all)in the ropivacaine group than in the control group,although the incidence of nausea and vomiting showed no significant difference between the two groups.The levels of epinephrine,norepinephrine,and cortisol were significantly lower in the ropivacaine group than in the control group at 24 and 48 h(P<0.01 for all). CONCLUSION Local wound infiltration with ropivacaine after open hepatectomy can improve postoperative pain relief,reduce surgical stress response,and accelerate postoperative recovery.

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.

Knowledge of Nursing Staff on Postoperative Pain: The Case of the Laquintinie Hospital in Douala, Cameroon

Background and objective: Pain is a major concern in the surgical environment, but its management remains insufficient due to several factors related to the nursing staff, the organization of the structure or the patient himself. The objective of this study was to assess the knowledge of the nursing staff on postoperative pain at the Laquintinie Hospital in Douala. Methodology: This was a cross-sectional study carried out at the Laquintinie Hospital in Douala from September to December 2018. Participants were consecutively selected among members of nursing staff in charge of operated patients in the visceral surgery, trauma surgery, surgical reanimation, gynaecology and obstetrics services. Socio-professional data and data related to knowledge of postoperative pain were collected from this personnel using a pre-tested semi-structured questionnaire. Results: With regard to knowledge of postoperative pain, the proportion of correct answers to the knowledge questions was 61.4%. This proportion varied significantly with the specific training received on pain and the specialization of the nursing staff (p < 0.001). Conclusion: The results of the study reveal knowledge in this population that deserves to be improved with a view to better management of patients undergoing surgery.

Effect of auricular acupoint sticking and pressing on postoperative pain of patients with mixed hemorrhoids:A Meta-analysis

Objective:To systematically evaluate the application effect of auricular acupuncture in postoperative analgesia in patients with mixed hemorrhoids.Methods:We searched Chinese Biomedical Literature Database,CNKI,WanFang,PubMed,Embase,and The Cochrane Library to collect randomized controlled trials about auricular acupuncture on Postoperative patients with mixed hemorrhoids.According to the inclusion criteria and exclusion criteria screening literature.RevMan 5.3 software was used for meta-analysis.Results:A total of 20 articles and 21 studies were included,including 1999 patients after mixed hemorrhoids.The control group was treated with routine nursing analgesia.The experimental group was treated with auricular acupressure beans based on the control group.The meta-analysis showed that the pain relief rate of the experimental group was better than that of the control group[OR=2.84,95%CI(2.12,3.80),P<0.05].Subgroup analysis showed that the application of auricular acupressure after milligan morgan was superior to the control group in the analgesic effect[OR=3.68,95%CI(2.62,5.18),P<0.05],but it is not yet possible to apply auricular acupoint pressing to relieve pain after Stapler hemorrhoidectomy(P>0.05).The pain scores of 24 hours and 48 hours after operation in the experimental group were lower than those of the control group,indicating that auricular acupoint sticking can relieve the pain after operation.The improvement of the postoperative anal margin edema was better in the experimental group than in the control group,24 h[SMD=-1.99,95%CI(-2.84,-1.14),P<0.05],48 h[SMD=-1.92,95%CI(-2.72,-1.11),P<0.05].The adverse reactions were lower than the control group.Conclusion:The application of ear acupoint pressure pea after external exfoliation of mixed hemorrhoids can improve the analgesic effect and reduce the symptoms of postoperative anal edge edema,and the price is low,the operation is convenient,and the side effects are few.It is recommended to be popularized in clinical practice.

The Third Year Anesthesiology Residents’ Knowledge Regarding Pediatric Postoperative Pain Management

Background: There are six Anesthesiology training centers in Thailand that are approved to operate the training program. An evidence of residents’ knowledge about pediatric postoperative pain management is needed for improving the program. Objective: To assess the third year anesthesiology residents’ knowledge about pediatric postoperative pain management. Materials and Methods: The questionnaire was adapted from previous studies. The questionnaire has 35 questions consisted of 17 multiple choice questions and 18 true or false questions to cover 2 domains: 1) use of age-appropriate pediatric pain assessment (10 questions) and 2) pediatric pain treatment (25 questions). Minimal passing level of the questionnaire rated by three young anesthesiology staffs was 76.2%. All 62 participants were the 3rd year anesthesiology residents from 6 training centers. Data were analyzed by descriptive statistics. Results: The response rate was 95.2%. Seventy-one percent of participants reported that they had learned about pediatric pain treatment. Of those, 55.9% rated their remaining knowledge at median level. The proportion of the correct score was 67.7% (mean 23.7 ± 2.9 SD) which was lower than the minimal passing level. The highest score was 29 and the lowest score was 16. For pain assessment domain;the mean proportion of correct score was 65% (range 90%-40%). For pain treatment domain;the mean proportion of correct score was 68.8% (range 88%-44%). Conclusion: Anesthesiology residents’ knowledge about pediatric postoperative pain management needs to be improved.

Preoperative Sedation, Hemodynamic Stability during General Anesthesia and Improving Postoperative Pain: Pregabalin Is the Answer

Background: Tracheal intubation is a noxious stimulus that tends to provoke a marked sympathetic response which is potentially deleterious in some patients. Various methods have been used to minimize and attenuate these potentially harmful responses. Aim of the study: The present study compared the efficacy and safety of two different doses (150 mg and 300 mg) of oral pregabalin premedication on attenuation of the hemodynamic pressor response to airway instrumentation, perioperative hemodynamic stability, preoperative sedation, and postoperative pain reduction. Patients and methods: This prospective, observational study consisted of 60 adult patients scheduled for laparoscopic cholecystectomy. The patients were randomized into three groups of 20 patients each. Group I (P0) received an oral placebo, group II (P150) received 150 mg of oral pregabalin and group III (P300) received 300 mg of oral pregabalin 1 h prior to induction. All patients were assessed for pre-operative sedation, perioperative hemodynamic changes, Post-operative pain and analgesic consumption. Results: Regarding the efficacy of the preoperative administration of oral pregabalin, a dose dependent attenuation in the increased in heart rate, systolic, and diastolic blood pressure, and mean arterial blood pressure resulting from laryngoscopy and intubation was observed (300 mg > 150 mg), along with a subsequent decrease in intraoperative fentanyl supplementation. On anxiolysis, patients were more comfortable and asleep in the pregabalin groups as compared with the control group, in which more patients were awake and agitated. Post-operative pain and analgesic consumption were effectively reduced by (150 mg and 300 mg) pregabalin in a dose-dependent manner. Postoperative nausea and vomiting were significantly lower with the administration of pregabalin compared with the placebo group (P < 0.008). Additionally, pregabalin increased the incidence of dizziness and visual disturbances in a dose-dependent manner. Conclusion: Oral pregabalin premedication adequately sedated patients and attenuated the hemodynamic pressor response to airway instrumentation in a dose-dependent manner. Premedicated patients were haemodynamically stable perioperatively without recovery time prolongation or side effects, except dizziness with 300 mg of oral pregabalin. Additionally, oral pregabalin reduced postoperative pain and analgesic consumption in a dose-dependent manner.

Comparative Study between the Benefit of Pre-Emptive Pregabalin and Gabapentin on Acute Postoperative Pain for Elective Gynecological Surgery

Gabapentin, and pregabalin had been used in analgesic field some studies. This double blind randomized clinical trial was conducted to evaluate the pre-emptive use of gabapentin 900 mg and pregabalin 300 mg in reducing postoperative pain. Methods: A total number of 75 patients undergoing lower gynecological procedures were prospectively randomized, into three groups (group A, B and C), each group including 25 patients with total 75 patients. Pregabalin, gabapentin or placebo, the pain was assessed on a visual analogue scale (VAS) at 0, 6, 12, 18 & 24 hours postoperatively. Duration of effective analgesia was documented, and administration of extra analgesic doses of meperedine required in the first 24 hours. Results: Patients in the gabapentin or pregabalin had significantly lower VAS scores at 6, 12, 18 and 24 hours, than those in the placebo group. As for rescue analgesia with mepredine consumed in the gabapentin, and pregabalin were significantly less than in the placebo. As for the complications, both drugs had increased incidence of nausea, vomiting and dizziness postoperatively, while no significance was found between all groups as regard hypotension, bradycardia and shivering. Conclusion: Preoperative use of pregabalin or gabapentin provides comparable but significant prolonged postoperative analgesia, less nausea and vomiting compared to placebo after gynecological surgeries. However, it was associated with increased incidence of postoperative dizziness.

Effectiveness of the Suprainguinal Ultrasound-Guided Block for the Management of Postoperative Pain after Application of a Total Hip Prosthesis

Objective: To assess the effectiveness of ultrasound-guided supraginguinal block (SIB) in the management of pain after total hip replacement. Material and Methods: This was a prospective, randomized, single-blind controlled study carried out in the anesthesia-intensive care unit of the Donka National Hospital in Conakry, over a period of 06 months (01/01/2020 to 30/06/2020). It concerned 32 patients: 16 patients in the “ultrasound-guided SIB” group and 16 patients in the “standard analgesia” group. Results: The pain scores assessed by the simple verbal scale and collected at the different time intervals (6H, 12H, 24H, 36H, 48H) showed mean scores < 1 in the ultrasound-guided SIB group while the mean scores were ≤3 in the standard analgesia group (P < 0.001). On movement, the mean pain scores were ≤1 for the ultrasound-guided SIB group versus mean scores > 3 in the standard analgesia group (P < 0.001). The time to mobilization was greater than 48 hours in all patients in the standard analgesia group while it was less than 48 hours in the majority of patients (75%) in the ultrasound-guided SIB group. Nausea and vomiting were the most observed side effects. We did not observe any respiratory distress. The length of day hospitalization of patients in the ultrasound-guided SIB group was on average 5.50 ± 0.52 compared with 13.44 ± 1.55 in the group of standard analgesia patients (P = 0.001). The vast majority of patients in the ultrasound-guided SIB group were satisfied and unhappy in the standard analgesia group. Conclusion: Our study demonstrated that echo-guided SIB provided better analgesia compared to standard analgesia for the management of postoperative pain after total hip replacement.
