Post-operative analgesic effect of intraperitoneal ropivacaine with or without tramadol in laparoscopic cholecystectomy

Efficacy and safety of intraperitoneal ropivacaine in pain management following laparoscopic digestive surgery: A systematic review and meta-analysis of RCTs

BACKGROUND

Managing postoperative pain effectively with an opioid-free regimen following laparoscopic surgery (LS) remains a significant challenge. Intraperitoneal instillation of ropivacaine has been explored for its potential to reduce acute postoperative pain, but its efficacy and safety are still under debate. This study aimed to evaluate the efficacy and safety of intraperitoneal instillation of ropivacaine for acute pain management following laparoscopic digestive surgery.

METHODS

We used PRISMA 2020 and a measurement tool to assess systematic reviews 2 guidelines to conduct this review. The random-effects model was adopted using Review Manager Version 5.4 for pooled estimates.

RESULTS

We retained 24 eligible RCTs involving 1705 patients (862 patients in the intraperitoneal instillation group and 843 patients in the control group). The intraperitoneal instillation group reduced total opioid consumption during the first 24 hours postoperatively (MD = -21.93 95% CI [-27.64, -16.23], P < .01), decreased pain scores at different time (4 hours, 8 hours, 12 hours and 24 hours), shorter the hospital stay (MD = -0.20 95% CI [-0.36, -0.05], P < .01), reduced the postoperative shoulder pain (MD = 0.18 95% CI [0.07, 0.44], P < .01), and decreased postoperative nausea and vomiting (MD = 0.47 95% CI [0.29, 0.77], P < .01).

CONCLUSION

Intraperitoneal instillation of ropivacaine appears to be an effective component of multimodal pain management strategies following laparoscopic digestive surgery, significantly reducing opioid consumption and improving postoperative recovery markers. Despite these promising results, additional high-quality trials are needed to confirm the efficacy and safety of this approach.

Efficacy of Intraperitoneal 0.2% Ropivacaine With Dexmedetomidine Versus 0.2% Ropivacaine With Ketamine in Laparoscopic Surgeries: A Randomized Controlled Trial

BACKGROUND

Effective pain management modalities are the armamentarium for enhanced recovery in laparoscopic surgeries. Intraperitoneal instillation of local anaesthetics with adjuvants is advantageous in minimizing pain. So, we designed this study with the aim to compare the analgesic effectiveness of intraperitoneal ropivacaine with adjuvants like dexmedetomidine versus ketamine for postoperative analgesia.

OBJECTIVE

 The objective of this study is to assess the total duration of analgesia and total rescue analgesic dose requirements in the first 24 hours postoperatively.

MATERIALS AND METHODS

A total of 105 consenting patients for elective laparoscopic surgeries were enrolled and divided into three groups by computer-generated randomization as follows: Group 1: 30 ml of 0.2% ropivacaine with ketamine 0.5 mg/kg diluted to 1 ml; Group 2: 30 ml of 0.2% ropivacaine with dexmedetomidine 0.5 mcg/kg diluted to 1 ml; Group 3: 30 ml of 0.2% ropivacaine with 1 ml of normal saline. The postoperative visual analogue scale (VAS) score, total duration of analgesia, and total analgesic dose were calculated and compared among the three groups.

RESULTS

The postoperative analgesic duration after intraperitoneal instillation of Group 2 was longer as compared to Group 1. The total analgesic requirement was lower in Group 2 as compared to Group 1, and the p-value was significant (p ≤ 0.001) for both parameters. Demographic parameters and VAS scores among the three groups were not statistically significant.

CONCLUSION

We conclude that intraperitoneal instillation of local anaesthetics with adjuvants is effective for postoperative analgesia in laparoscopic surgeries, and ropivacaine 0.2% with dexmedetomidine 0.5 mcg/kg is more effective when compared to ropivacaine 0.2% with ketamine 0.5 mg/kg.

Comparative Study Between Early versus Late Intraperitoneal Administration of Either Bupivacaine/Tramadol or Bupivacaine/Dexmedetomidine for Perioperative Analgesia in Abdominal Laparoscopic Cancer Surgeries: A Prospective Randomized Study

Objective

Several modalities for analgesia after laparoscopic procedures have been used. This study aimed to investigate the efficacy of early versus late bupivacaine/tramadol combination and bupivacaine/dexmedetomidine combination in analgesia for laparoscopic cancer surgeries.

Methods

A total of 100 patients of both genders scheduled for elective laparoscopic cancer surgeries were included. Patients were randomly assigned to one of four groups each comprises 25 patients. Group 1: early bupivacaine/tramadol, Group 2: late bupivacaine/tramadol, Group 3: early bupivacaine/dexmedetomidine, and Group 4: late bupivacaine/dexmedetomidine. Early groups received the intraperitoneal instillation before start of surgery and late groups received the instillation after completion of surgery. Perioperative heart rate (HR) and mean arterial blood pressure (MAP) were recorded. The degree of postoperative pain was measured at rest and with cough using Visual analogue scale (VAS) score at 2, 4, 6, 12, 18 and 24 h after surgery. In addition, the total intraoperative fentanyl and postoperative morphine doses were calculated.

Results

Both late bupivacaine/tramadol, bupivacaine/dexmedetomidine groups had longer time to receive first analgesic requirement (13.4±3.9, 11.3±3.9 h) respectively as compared to early bupivacaine/tramadol, bupivacaine/dexmedetomidine groups (9.8± 3.6, 8.4± 2.8 h), respectively. Between each early and late group, intraoperative fentanyl consumption was higher for the late groups (75± 22.8, 73± 21.55µg) versus (32.7± 10.9, 37.5± 13.3 µg), respectively. As regards to rescue analgesic requirements, both early bupivacaine/tramadol and bupivacaine/dexmedetomidine groups consumed more analgesics (5.2± 2.0 and 6.1± 1.8 mg) as compared to the late groups (3.2± 0.8 and 4.3± 1.5 mg), respectively. The four groups were comparable for their perioperative HR and MAP values.

Conclusion

Intraperitoneal instillation of bupivacaine/tramadol and bupivacaine/dexmedetomidine could be considered an effective route for analgesic administration during laparoscopic cancer surgeries. Early instillation reduced the intraoperative opioid consumption and late instillation resulted in reduced postoperative opioid consumption.

Comparison between pre-emptive oral tramadol and tapentadol for attenuation of catheter-related bladder discomfort and surgical stress response in patients undergoing transurethral resection of prostate: A prospective, randomised, double-blind trial

Background and Aims:

Surgical interventions involving urinary catheterisation often lead to catheter-related bladder discomfort (CRBD). With a very high incidence rate of 47%–90%, CRBD often leads to a distressing and painful recovery after surgery. Although many opioids have been used for the treatment of CRBD, the search for the best is still going on. This study investigated the efficacy and tolerability of oral tapentadol and tramadol on postoperative CRBD.

Methods:

This was a prospective, randomised double-blind study. 100 patients, undergoing transurethral resection of the prostate were randomly assigned into two groups to receive tramadol 100 mg (Group A) or tapentadol 50 mg (Group B) orally 1 h before surgery. CRBD was evaluated on a 4-point severity scale in the post-operative area at 0, 0.5, 1, 2, 3, 4, 5 and 6 h. Pain and adverse effects were assessed postoperatively. Serum cortisol levels before and after the procedure were noted. Statistical analysis was done with the analysis of variance, t test.

Results:

Postoperative CRBD, 2 h after surgery was significantly reduced in group B than group A (P = 0.012). Cortisol levels, postoperatively were significantly lower in Group B (113 ± 65.45) (P = 0.001) than group A (162.64 ± 118.84 ng/dL). Dry mouth was seen in four, nausea in eight and sedation in six patients in group A while none in group B. 14 patients in Group A and one patient in Group B needed intravenous paracetamol (P = 0.000).

Conclusions:

Premedication with tapentadol was more effective in reducing CRBD and pain postoperatively. The surgical stress response and side effects were significantly reduced with tapentadol.

Postoperative analgesic efficacy of the pulmonary recruitment manoeuvre compared to intraperitoneal hydrocortisone in laparoscopic gynaecological surgeries

Background and Aims

Laparoscopic surgeries are becoming attractive because of early recovery. Adequate postoperative pain relief may be a major concern. Several methods have been used to relieve laparoscopic postoperative pain.

Methodology

This prospective, randomised, controlled study was conducted during the period between February and June 2019. Patients were assigned into three groups. Patients in the hydrocortisone group received intraperitoneal 100mg hydrocortisone in 150 ml normal saline together with the routine method to remove carbondioxide (CO2). For patients in the pulmonary recruitment group, CO₂ was exsufflated by pulmonary recruitment manoeuvre together with the routine method to remove CO₂. In the control group CO₂ was removed by applying gentle abdominal pressure allowing passive exsufflation through the port site.

Results

A total of 57 patients were included in the study. There was no statistically significant difference between the three groups as regards demographic characteristics. There was a statistically significant difference in the 24 h postoperative analgesic consumption (primary outcome) in the hydrocortisone and pulmonary recruitment groups in comparison to the control group:P value <0.001. Also, time to first request for analgesia was significantly longer and the visual analogue scale (VAS) score was significantly lower in the hydrocortisone and pulmonary recruitment groups compared to the control group:P value <0.001.

Conclusion

Intraperitoneal hydrocortisone and pulmonary recruitment manoeuvre could both effectively reduce pain after gynaecological laparoscopic surgeries, however, intraperitoneal hydrocortisone might give a longer pain-free time.
