Combined lumbar muscle block and perioperative comprehensive patient-controlled intravenous analgesia with butorphanol in gynecological endoscopic surgery

BACKGROUND Laparoscopic surgery has become a common surgical approach for the clinical treatment of intra-abdominal lesions in recent years.We hypothesized that lumbar block with postoperative patient-controlled intravenous analgesia(PCIA)by butorphanol after gynecological surgery under general anesthesia would be more effective than PCIA by butorphanol alone.AIM To investigate the effect of lumbar block with PCIA by butorphanol after gynecological surgery under general anesthesia.METHODS This study assessed 120 women scheduled for laparoscopic surgery at our hospital between May 2017 and May 2020.They were divided using a random number table into a research group(those who received quadratus lumborum block combined with PCIA analgesia by butorphanol)and a control group(those who received only PCIA analgesia by butorphanol),with 60 patients in each group.Demographic factors,visual analog scale scores for pain,serum inflammatory markers,PCIA compressions,Ramsay scores,and adverse events were compared between groups using a t-test,analysis of variance,orχ2 test,as appropriate.RESULTS There were no significant differences in demographic factors between groups(all P>0.05).The visual analog scale scores of the research group in the resting state 12 h and 24 h postoperatively were significantly lower than those of the control group(P<0.05).Two hours after surgery,there were no significant differences in the levels of serum tumor necrosis factor-α,interleukin(IL)-6,or IL-8 between groups(P>0.05).The serum tumor necrosis factor-αlevels of the research group 24 h postoperatively were significantly lower than those of the control group(P<0.05).The levels of serum IL-6 and IL-8 in the study group 24 h and 48 h postoperatively were significantly lower than those in the control group(P<0.05).CONCLUSION Lumbar block with PCIA with butorphanol after gynecological surgery under general anesthesia significantly improves the analgesic effect and reduces the degree of inflammation,instances of PCIA compression,and adverse reactions.

Comparison of oxycodone and sufentanil in patient-controlled intravenous analgesia for postoperative patients:a meta-analysis of randomized controlled trials

Background:Managing acute postoperative pain is challenging for anesthesiologists,surgeons,and patients,leading to adverse events despite making significant progress.Patient-controlled intravenous analgesia(PCIA)is a recommended solution,where oxycodone has depicted unique advantages in recent years.However,controversy still exists in clinical practice and this study aimed to compare two drugs in PCIA.Methods:We performed a literature search in PubMed,Embase,the Cochrane Central Register of Controlled Trials,Web of Science,Chinese National Knowledge Infrastructure,Wanfang,and VIP databases up to December 2020 to select specific randomized controlled trials(RCTs)comparing the efficacy of oxycodone with sufentanil in PCIA.The analgesic effect was the primary outcome and the secondary outcome included PCIA consumption,the Ramsay sedation scale,patients’satisfaction and side effects.Results:Fifteen RCTs were included in the meta-analysis.Compared with sufentanil,oxycodone showed lower Numerical Rating Scale scores(mean difference[MD]=-0.71,95%confidence interval[CI]:-1.01 to-0.41;P<0.001;I^(2)=93%),demonstrated better relief from visceral pain(MD=-1.22,95%CI:-1.58 to-0.85;P<0.001;I^(2)=90%),promoted a deeper sedative level as confirmed by the Ramsay Score(MD=0.77,95%CI:0.35-1.19;P<0.001;I^(2)=97%),and resulted in fewer side effects(odds ratio[OR]=0.46,95%CI:0.35-0.60;P<0.001;I^(2)=11%).There was no statistical difference in the degree of patients'satisfaction(OR=1.13,95%CI:0.88-1.44;P=0.33;I^(2)=72%)and drug consumption(MD=-5.55,95%CI:-14.18 to 3.08;P=0.21;I^(2)=93%).Conclusion:Oxycodone improves postoperative analgesia and causes fewer adverse effects,and could be recommended for PCIA,especially after abdominal surgeries.Registration:PROSPERO;https://www.crd.york.ac.uk/PROSPERO/;CRD42021229973.

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.

Effect of Transcutaneous Electrical Acupoint Stimulation on Nausea and Vomiting Induced by Patient Controlled Intravenous Analgesia with Tramadol

Objective： To observe the effect of transcutaneous electrical acupoint stimulation （TEAS） on nausea and vomiting （N＆V） induced by patient controlled intravenous analgesia （PCIA） with Tramadol. Methods： Sixty patients who were ready to receive scheduled operation for tumor in the head-neck region and post-operation PCIA, aged 39-65 years, with the physique grades Ⅰ -Ⅱ of ASA, were randomized into two groups, A and B, 30 in each group. The pre-operation medication, induction of analgesia and continuous anesthesia used in the two groups were the same. TEAS on bilateral Hegu （LI4） and Neiguan （PC6） points was intermittently applied to the patients in group A starting from 30 min before analgesia induction to 24 h after operation, and the incidence and score of nausea and vomiting, antiemetic used, visual analogue scores （VAS）, and PCIA pressing times in 4 time segments （0-4, 4-8, 8-12 and 12-24 h after the operation was finished） were determined. The same management was applied to patients in Group B, with sham TEAS for control. Results： The incidence and degree of N＆V, as well as the number of patients who needed remedial antiemetic in Group A were less than those in Group B. The VAS score and PCIA pressing time were lower in Group A than those in Group B in the corresponding time segments respectively. Conclusion： TEAS could prevent N＆V induced by PCIA with Tramadol.

Trigeminal extracranial thermocoagulation along with patientcontrolled analgesia with esketamine for refractory postherpetic neuralgia after herpes zoster ophthalmicus:A case report

BACKGROUND Primary trigeminal neuralgia can achieve satisfactory results through clinical treatment and intervention.The pathogenesis of neuralgia caused by varicellazoster virus infection of the trigeminal nerve is more complex,and it is still difficult to relieve the pain in some patients simply by drug treatment or surgical intervention.CASE SUMMARY A 66-year-old woman was hospitalized with herpetic neuralgia after herpes zoster ophthalmicus(varicella-zoster virus infects the ophthalmic branch of the trigeminal nerve).On admission,the patient showed spontaneous,electric shocklike and acupuncture-like severe pain in the left frontal parietal region,and pain could be induced by touching the herpes area.The numerical rating scale(NRS)was 9.There was no significant pain relief after pulsed radiofrequency and thermocoagulation of the ophthalmic branch of the trigeminal nerve.Combined with patient-controlled intravenous analgesia(PCIA)with esketamine,neuralgia was significantly improved.The patient had no spontaneous pain or allodynia at discharge,and the NRS score decreased to 2 points.The results of follow-up 2 mo after discharge showed that the NRS score was≤3,and the Pittsburgh Sleep Quality Index score was 5 points.There were no adverse reactions.CONCLUSION Trigeminal extracranial thermocoagulation combined with esketamine PCIA may be a feasible method for the treatment of refractory herpetic neuralgia after herpes zoster ophthalmicus.

Patient-controlled intravenous fentanyl for cystospasm after transurethral resection of the prostate

Objective： To evaluate the clinical efficacy and safety of patient-controlled intravenous analgesia （PCIA） with fentanyl for cystospasm after transurethral resection of the prostate. Methods： Sixty benign prostatic hyperplasia （BPH） patients scheduled for transurethral resection of the prostate （TURP） under general anesthesia with laryngeal mask airway （LMA） were randomly divided into groups F and S. Group F （n=30） received PCIA device with fentanyl 10 ug/kg＋8 mg ondansetron, and Group S （n=30） received placebo （PCIA device with 8 mg ondansetron）. The visual analog scale （VAS） scores for pain were evaluated at 0, 2, 4, 8, 16, 24, and 48 h by the same staff. And recorded were incidence of cystospasm, side effects, application of hemostatic, duration of drawing Foley catheter and continuous bladder irrigation, time of exhaust after operation, time of post-operative stay and cost of hospitalization. Results： The incidence of cystospasm in Group F was significantly lower than that in Group S in the 48 h after operation （P〈0.05）, the VAS scores for pain in Group F was significantly lower than that in Group S within the 48 h after operation （P〈0.01）. The time of exhaust after operation in Group F was significantly later than in Group S （P〈0.05）. No significant difference was observed in applications of hemostatic, duration of drawing Foley catheter, duration of continuous bladder irrigation, time of post-operative stay and cost of hospitalization between the 2 groups. Conclusion： PCIA with fentanyl （10 ug/kg） relieves pain with little side effect and reduces cystospasm satisfactorily.

A systematic Review of the Safety and Effectiveness of Epidural Analgesia for Labor Analgesia

Objective To re-evaluate the systematic review of the safety and effectiveness of epidural analgesia(EA)for labor analgesia.Methods The Cochrane database,PubMed,EMBASE,EBSCO,Web of Science,ScienceDirect,China Biomedical Literature database,CNKI,Wanfang and VIP databases were searched,and the search time was limited to August 2020.Two researchers screened the literature and extracted data according to the inclusion criteria.AMSTAR was used to evaluate the methodological quality of the included studies.Pain intensity and pain relief satisfaction were used as the main indicators for re-evaluation of the effectiveness.Midwifery rate,cesarean section rate,back pain,fever,nausea and vomiting,umbilical artery pH value,and newborn Apgar score were used as the main indicators to re-evaluate the safety.Results and Conclusion A total of 9 meta-analyses were included.The safety and effectiveness of EA and opioid intravenous analgesia,acupuncture stimulation,inhalation analgesia,no analgesia,and continuous delivery were evaluated separately.The included systematic reviews showed that EA could increase the rate of device-assisted delivery,causing maternal fever,and prolonging the first and second stages of labor.But the incidence of back pain,nausea,and vomiting was lower.Therefore,analgesia had a good effect with better satisfactory degree.Current evidence shows that EA is safe and effective for labor analgesia,but the quality of the reports of current studies is not high.
