Comparison of Efficacy and Safety of Oxycodone Versus Fentanyl for Intravenous Patient-Controlled Analgesia in Postoperative Pain Management:A Systematic Review and Meta-Analysis

Backgroud:Intravenous opioid patient-controlled analgesia(IV-PCA)has been suggested as an effective method in postoperative pain management.There are several randomized controlled trials(RCTs)of comparison of oxycodone and fentanyl for IV-PCA in surgical patients.The purpose of this study was to perform a meta-analysis to compare the efficacy and safety of oxycodone and fentanyl for IV-PCA in surgical patients from current data.Methods:The RCTs of oxycodone versus fentanyl for IV-PCA were gathered from PubMed,Embase,Cochrane library,CNKI and VIP data.After data extraction and quality assessment of the included RCTs,the RevMan 5.3 software was applied for meta-analysis of numerical rating scale(NRS)scores,accumulated IV-PCA consumption of oxycodone and fentanyl,patient satisfaction,postoperative nausea and vomiting(PONV),and other adverse events(AEs).Results:Results reported from eight RCTs involving 600 patients are included in the meta-analysis.The NRS score at rest and upon movement of group oxycodone was significantly lower than that of group fentanyl(WMD=-3.85,95%CI-4.93^-2.76,P<0.00001;WMD=-4.31,95%CI-5.79^-2.84,P<0.00001);however,the incidence of PONV and dizziness was obviously increased in group oxycodone than in group fentanyl(OR=2.41,95%CI 1.60~3.63,P<0.0001;OR=3.69,95%CI 2.17~6.26,P<0.00001).Accumulated IV-PCA consumption in group oxycodone was less than in group fentanyl overall the 48 hours postoperatively(WMD=-12.11,95%CI-18.42^-5.80,P=0.0002).There was no significant difference in patient satisfaction between oxycodone and fentanyl(OR=0.73,95%CI 0.11~5.04,P=0.75).Conclusion:According to the evidence,this meta-analysis suggest that oxycodone for IV-PCA is superior to fentanyl in postoperative pain relief,whereas the higher incidence of PONV and dizziness was accompanied with oxycodone.Further large-scale,prospective,observational studies are needed to summarize and analyse the data to draw a fair conclusion.

Application of dezocine patient-controlled epidural analgesia in postoperative analgesia in patients with total myomectomy

BACKGROUND Uterine fibroids are common benign gynecological conditions.Patients who experience excessive menstruation,anemia,and pressure symptoms should be administered medication,and severe cases require a total hysterectomy.This procedure is invasive and causes severe postoperative pain,which can affect the patient’s postoperative sleep quality and,thus,the recovery process.AIM To evaluate use of dezocine in patient-controlled epidural analgesia(PCEA)for postoperative pain management in patients undergoing total myomectomy.METHODS We selected 100 patients undergoing total abdominal hysterectomy for uterine fibroids and randomized them into two groups:A control group receiving 0.2%ropivacaine plus 0.06 mg/mL of morphine and an observation group receiving 0.2%ropivacaine plus 0.3 mg/mL of diazoxide in their PCEA.Outcomes assessed included pain levels,sedation,recovery indices,PCEA usage,stress factors,and sleep quality.RESULTS The observation group showed lower visual analog scale scores,shorter postoperative recovery indices,fewer mean PCEA compressions,lower cortisol and blood glucose levels,and better polysomnographic parameters compared to the control group(P<0.05).The cumulative incidence of adverse reactions was lower in the observation group than in the control group(P<0.05).CONCLUSION Dezocine PCEA can effectively control the pain associated with total myomectomy,reduce the negative impact of stress factors,and have less impact on patients’sleep,consequently resulting in fewer adverse effects.

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.

Effects of oxycodone and fentanyl patient-controlled intravenous analgesia on pain, immune response and stress response after laparoscopic surgery

Objective:To study the effects of oxycodone and fentanyl patient-controlled intravenous analgesia on pain, immune response and stress response after laparoscopic surgery.Methods:Patients undergoing laparoscopic surgery in Xianning Central Hospital between June 2015 and February 2017 were selected and randomly divided into oxycodone group and fentanyl group who received postoperative oxycodone and fentanyl patient-controlled intravenous analgesia respectively. 3 d after surgery and 5 d after surgery, the serum contents of pain-related transmitters, immune indexes, stress-related molecules as well as peripheral blood contents of immune cells were measured.Results: 3 d after surgery and 5 d after surgery, CRP, TNF-α, IL-8, sICAM-1, YKL-40, Cor, C-P, FT3, FT4 and HO-1 contents in serum of oxycodone group were significantly lower than those of fentanyl group whereas CD3+CD4+T cell and CD3+CD8+T cell contents in peripheral blood as well as C3 and C4 contents in serum were significantly higher than those of fentanyl group.Conclusion:oxycodone patient-controlled intravenous analgesia after laparoscopic surgery is better than fentanyl and can reduce the pain degree, inhibit the stress response and improve the immune response.

Effect of buprenorphine transdermal patch combined with patient-controlled intravenous analgesia on the serum pain-related biochemical indexes in elderly patients with intertrochanteric fracture

Objective:To study the effect of buprenorphine transdermal patch combined with patient-controlled intravenous analgesia on the serum pain-related biochemical indexes in elderly patients with intertrochanteric fracture.Methods: A total of 92 elderly patients with intertrochanteric fracture who received surgical treatment in the hospital between August 2014 and January 2017 were collected and divided into control group (n=46) and observation group (n=46) according to the random number table method. The control group received patient-controlled intravenous analgesia, and the observation group received buprenorphine transdermal patch combined with patient-controlled intravenous analgesia. Differences in serum levels of inflammatory factors, oxidative stress indexes and pain mediators of two groups of patients were measured before and 24h after surgery.Results: Differences in serum levels of inflammatory factors, oxidative stress indexes and pain mediators were not statistically significant between the two groups before surgery;24 h after surgery, serum IL-1β, IL-6, IL-8, TNF-α, MDA, SP, PGE2, 5-HT, HA and NPY levels of both groups of patients increased significantly while SOD, TAC and CAT levels decreased significantly, and serum IL-1β, IL-6, IL-8, TNF-α, MDA, SP, PGE2, 5-HT, HA and NPY levels of observation group were lower than those of control group while SOD, TAC and CAT levels were higher than those of control group.Conclusion: Buprenorphine transdermal patch combined with patient-controlled intravenous analgesia can effectively inhibit the expression of pain-related indexes and relieve early postoperative pain intensity in elderly patients with intertrochanteric fracture.

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.

APPLICATION OF LORNOXICAM TO PATIENT-CONTROLLED ANALGESIA IN PATIENTS UNDERGOING ABDOMINAL SURGERIES

Objective To assess the efficacy and safety of lornoxicam, one non-steroidal anti-inflammatory drug (NSAID) in patient-controlled analgesia (PCA) in patients undergoing abdominal surgeries. Methods Thirty-nine patients scheduled for abdominal surgeries were randomly assigned to different PCA treatment groups using either lornoxicam or fentanyl postoperatively. Pain intensity difference (PID) and sum of pain intensity difference (SPID) were used to assess the analgesic efficacy of both drugs during a 24-hour period. Results The analgesic efficacy of lornoxicam is 1/66 of fentanyl, which was shown by SPID value of 3.250 and 3.058, respectively (P > 0.05). Lornoxicam caused fewer adverse events than fentanyl (33% vs. 68%, P < 0.05). Conclusion In clinic, we can use lornoxicam to treat postoperative pain effectively and with less adverse reactions com-pared with fentanyl.

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.

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.

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.

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.

Intravenous Lidocaine for Perioperative Use

Introduction and Background: Lidocaine was recognised only as a local anesthetic and anti-arrhythmic drug for past decades. Nonetheless, more recently its utility in perioperative setting is being appreciated globally. This review aims to analyse its work beyond its traditional use when employed intravenously in perioperative setting and overall impact on postoperative period. Content: A total of 41 articles were selected for study while 13 of them were chosen for data presentation. Databases such as CENTRAL, MEDLINE/Pubmed, LILACS, Ovid and Scielo were used to search the articles using keywords like Intravenous lidocaine, local anesthetics, perioperative analgesia or postoperative pain. A bolus dose of 1.5 mg/kg and maintenance dose of 2 - 3 mg/kg/h of intravenous lidocaine was used to bring out its analgesic effect and its positive impact on postoperative stage in nearly all the selected studies. Its anti-inflammatory, antinociceptive and immunomodulatory effects were also addressed. Conclusion: Perioperative implication of systemic lidocaine not only lessens pain perception but also assures early return of bowel function, lower incidence of postoperative nausea and vomiting, opioid sparing effect and shorter length of hospital stay. Thus, implementation of lidocaine as a part of perioperative approach should be seriously considered. Its role in surgeries other than abdominal needs more detailed study. In spite of current results encouraging, it may be too early to claim its similar impact in other types of surgeries.

目的分析手术患者接受患者自控静脉镇痛(patient controlled intravenous analgesia,PCIA)期间发生术后恶心呕吐(postoperative nausea and vomiting,PONV)的危险因素。方法本研究为回顾性队列研究,纳入2023年7月1日—10月31日在北京协和医院接受外科手术且术后接受PCIA的患者。通过电子病历系统获取患者的一般资料、既往史、手术信息、术中用药信息、术后镇痛随访信息。根据接受PCIA期间PONV的发生情况,将患者分为PCIA⁃PONV组和非PCIA⁃PONV组;根据是否发生术后呕吐(postoperative vomiting,POV),将其分为PCIA⁃POV组和非PCIA⁃POV组。采用多因素Logistic回归分析法筛选PCIA⁃PONV和PCIA⁃POV的危险因素。结果共纳入1373例患者,其中PCIA⁃PONV组676例,PCIA⁃PONV的发生率为49.2%;PCIA⁃POV组285例,PCIA⁃POV的发生率为20.8%。多因素Logistic回归分析显示,女性(OR=2.134,95%CI:1.590~2.865,P<0.001)、腹部手术(OR=1.655,95%CI:1.253~2.186,P<0.001)是手术患者接受PCIA期间出现PONV的危险因素,而年龄增长(OR=0.990,95%CI:0.982~0.998,P=0.019)、体质量指数增加(OR=0.961,95%CI:0.932~0.991,P=0.012)则是其保护因素;女性(OR=2.646,95%CI:1.754~3.992,P<0.001)、全麻史(OR=1.372,95%CI:1.042~1.806,P=0.024)、术中使用大剂量阿片类药物(OR=1.607,95%CI:1.206~2.142,P=0.001)是手术患者接受PCIA期间出现POV的危险因素,而术中未使用肌松拮抗剂(OR=0.393,95%CI:0.237~0.651,P<0.001)则是其保护因素。结论本研究初步揭示了手术患者接受PCIA期间发生PONV的危险因素,完善的术前评估及合理的围术期管理策略对于预防PCIA⁃PONV具有重要意义。

超声引导胸椎旁神经阻滞复合PCIA在开腹肝脏部分切除手术后镇痛中的应用:一项随机对照试验

目的比较超声引导胸椎旁神经阻滞(thoracic paravertebral block,TPVB)复合患者自控静脉镇痛(patient-controlled intravenous analgesia,PCIA)与单纯患者自控静脉镇痛用于开腹肝脏部分切除手术术后镇痛的效果。方法选择重庆医科大学附属第一医院2020年9月至2022年9月择期行开腹肝脏部分切除手术患者120例,采用电脑随机数字法将奇数号分入超声引导胸椎旁神经阻滞复合PCIA组(A组),偶数号分入单纯患者自控静脉镇痛组(B组),每组60例,最终纳入符合标准的患者112例并完成统计分析。A组患者麻醉诱导前于左侧卧位行超声引导下T8~T9节段胸椎旁神经阻滞,注射0.33%罗哌卡因30 mL,B组患者不行超声引导胸椎旁神经阻滞,2组患者术后均连接PCIA镇痛泵。主要观察指标为2组患者术后4、8、12、24、48 h痛觉减退平面以及静息和活动时VAS疼痛评分;次要观察指标为术中平均心率和平均动脉压力、术后首次补救镇痛需求时间、术后48 h补救镇痛人数、术后首次下地活动时间、术后肛门排气时间、术后总住院天数以及术后不良反应发生率。结果与B组患者比较,A组患者术后4、8、12、24 h静息及咳嗽VAS评分降低(P<0.001),术中平均心率、平均动脉血压明显降低(P<0.01);48 h内曲马多累计消耗量减少(P=0.018),术后首次补救镇痛需求时间延长(P<0.001);术后PCIA平均有效按压次数、补救镇痛人数均明显减少(P<0.001);首次下地活动时间和肛门排气时间显著提前(P<0.001)。患者术后48 h VAS评分、术后总住院天数及术后不良反应发生率差异无统计学意义。结论超声引导胸椎旁神经阻滞复合PCIA在开腹肝部分切除术后镇痛效果优于单纯PCIA,术中循环更稳定,促进术后快速康复。
