Transversus abdominis plane infiltration for laparoscopic gastric banding: A pilot study.

ABSTRACT: AIM:To estimate an effect size for the transversus abdominis plane (TAP) infiltration on quality of recovery in patients undergoing laparoscopic gastric band surgery. METHODS:The pilot study was a randomized, double blinded, placebo controlled trial. Patients undergoing laparoscopic gastric band surgery were randomized to receive a bilateral TAP infiltration with 20 mL of 0.5% ropivacaine or saline. The evaluated outcomes included quality of recovery-40 (QoR-40) at 24 h, postoperative opioid consumption and pain. Data was examined using the Mann-Whitney U test. RESULTS:Nineteen subjects were recruited. There was a positive trend favoring the TAP infiltration group in global QoR-40 scores at 24 h after surgery, median [interquartile range (IQR)] of 175.5 (170-189) compared to 170 (160-175) in the control group (P = 0.06). There also a positive trend toward a lower cumulative opioid consumption in the TAP infiltration group, median (IQR) of 7.5 (2.5-11.5) mg iv morphine equivalents compared to 13 (7-21.5) in the control group (P = 0.07). Correlation analysis (Spearman's Rho) demonstrated an inverse relationship between 24 h cumulative opioid consumption and global QoR-40 scores, -0.49 (P = 0.03). CONCLUSION:The use of multimodal analgesic techniques to reduce opioid related side effects is particularly desirable in morbidly obese patients undergoing gastric reduction surgery. The TAP infiltration seems to have a clinically important effect in reducing postoperative opioid consumption and improve quality of recovery after laparoscopic gastric band surgery in morbid obese patients. Future studies to confirm the beneficial effects of the TAP infiltration in these patients are warranted.

Project description:BackgroundTransversus abdominis plane (TAP) infiltration has been increasingly used for postsurgical analgesia in abdominal/pelvic procedures; however, duration/extent of analgesia with standard local anesthetics is limited. This pilot study assessed the preliminary efficacy and safety of two volumes of liposome bupivacaine administered via TAP infiltration in patients undergoing robotic laparoscopic prostatectomy.MethodsIn this single-center, open-label, prospective study, patients older than 18 years received TAP infiltration with liposome bupivacaine immediately after surgery. The first 12 patients received a total volume of 20 mL liposome bupivacaine (266 mg); the next 12 received 40 mL liposome bupivacaine (266 mg). The liposome bupivacaine was diluted with 0.9% normal saline. The primary efficacy measure was duration of analgesia, measured by time to first opioid administration. Secondary outcome measures included patient-assessed pain scores, opioid use, and opioid-related adverse events (AEs).ResultsTwenty-four patients received liposome bupivacaine (20 mL, n=12; 40 mL, n=12) and were included in the primary analysis. Three refused participation in a 10-day follow-up visit and did not complete the study. Median time to first opioid administration after surgery was 23 and 26 minutes for the 20 and 40 mL groups, respectively. Mean total amount of postsurgical opioids ranged from 25.4 to 27.3 mg; after hospital discharge to day 10, both groups required a mean of 0.7 oxycodone/acetaminophen tablets/day. Mean pain scores of 4.4 and 5.3 were reported at 1 hour and 3.1 and 3.9 at 2 hours postsurgery, with 20 and 40 mL doses, respectively. Neither group had mean scores higher than 3.0 at any further assessments. No opioid-related or treatment-related serious AEs were reported.ConclusionMedian time to first opioid administration did not differ between the two groups. No differences in secondary outcomes were observed on the basis of volume administered. These initial findings suggest further study of liposome bupivacaine administered via TAP infiltration as part of a multimodal analgesic regimen in laparoscopic robotic prostatectomy may be warranted.

Project description:BackgroundThe transversus abdominis plane (TAP) block is an important non-narcotic adjunct for post-operative pain control in abdominal surgery. Surgeons can use laparoscopic guidance for TAP block placement (LTAP), however, direct comparisons to conventional ultrasound-guided TAP (UTAPs) have been lacking. The aim of this study is to determine if surgeon placed LTAPs were non-inferior to anesthesia placed UTAPs for post-operative pain control in laparoscopic colorectal surgery.MethodsThis was a prospective, randomized, patient and observer blinded parallel-arm non-inferiority trial conducted at a single tertiary academic center between 2016 and 2018 on adult patients undergoing laparoscopic colorectal surgery. Narcotic consumption and pain scores were compared for LTAP vs. UTAP for 48 h post-operatively.Results60 patients completed the trial (31 UTAP, 29 LTAP) of which 25 patients were female (15 UTAP, 10 LTAP) and the mean ages (SD) were 60.0 (13.6) and 61.5 (14.3) in the UTAP and LTAP groups, respectively. There was no significant difference in post-operative narcotic consumption between UTAP and LTAP at the time of PACU discharge (median [IQR] milligrams of morphine, 1.8 [0-4.5] UTAP vs. 0 [0-8.7] LTAP P = .32), 6 h post-operatively (5.4 [1.8-17.1] UTAP vs. 3.6 [0-12.6] LTAP P = .28), at 12 h post-operatively (9.0 [3.6-29.4] UTAP vs. 7.2 [0.9-22.5] LTAP P = .51), at 24 h post-operatively (9.0 [3.6-29.4] UTAP vs. 7.2 [0.9-22.5] LTAP P = .63), and 48 h post-operatively (39.9 [7.5-70.2] UTAP vs. 22.2 [7.5-63.8] LTAP P = .41). Patient-reported pain scores as well as pre-, intra-, and post-operative course were similar between groups. Non-inferiority criteria were met at all post-op time points up to and including 24 h but not at 48 h.ConclusionsSurgeon-delivered LTAPs are safe, effective, and non-inferior to anesthesia-administered UTAPs in the immediate post-operative period.Trial registryThe trial was registered at clinicaltrials.gov Identifier NCT03577912.
