RESUMEN
OBJECTIVE: To assess the effect of bilateral ultrasound-guided transversus abdominis plane block with ropivacaine compared with placebo as part of a multimodal analgesic regimen. DESIGN: A randomized, double-blind, placebo-controlled trial following the CONSORT criteria. SETTING: Hvidovre University Hospital. PATIENTS: Forty-six women scheduled for total abdominal hysterectomy. INTERVENTION: Women received either ropivacaine 0.75%, 20 mL (n = 24) or 0.9% saline, 20 mL (n = 24) in the transversus abdominis plane on each side. MAIN OUTCOME MEASURES: Primary outcome was the 24-h postoperative morphine consumption. Secondary outcomes were pain scores at rest and during coughing, postoperative nausea and vomiting at 1, 2, 4, 6, 8, and 24 h, and time to first mobilization. RESULTS: There was no difference in the mean 24-h postoperative morphine consumption between the two groups (p = 0.733). The ropivacaine group had significantly lower median pain scores at 1 h (p = 0.008) and 2 h (p = 0.027) postoperatively at rest and at 8 h (p = 0.028) during coughing. There was no significant difference in other secondary outcomes. CONCLUSION: There was no reduction in 24-h morphine consumption when using an ultrasound-guided transversus abdominis plane block in women undergoing total abdominal hysterectomy. As part of a multimodal regimen the transversus abdominis plane block showed some effect on pain scores at rest only in the early postoperative period.

OBJECTIVE: To assess the effect of systematic local infiltration analgesia on postoperative pain in vaginal hysterectomy, and describe the technique in detail. DESIGN: A randomized, double-blind, placebo-controlled study following the CONSORT criteria. SETTING: A university hospital. PATIENTS: Thirty-seven patients undergoing vaginal hysterectomy. METHODS: Patients received high-volume (50 mL) ropivacaine 0.50% (n = 20) or saline (n = 17) infiltration using a systematic technique ensuring uniform delivery to all tissues incised, handled or instrumented during the procedure. MAIN OUTCOME MEASURES: Pain, nausea, vomiting and opioid requirements were assessed for 32 h as well as time spent in the post-anesthesia care unit and time to first mobilization. RESULTS: Pain at rest was significantly reduced after one, four and eight hours in the ropivacaine group (p ≤ 0.001-0.01). Pain during coughing was significantly reduced after one and four hours (p ≤ 0.001 and p ≤ 0.003), and pain during movement was significantly reduced after four hours (p ≤ 0.02). Opioid requirements and time spent in the post-anesthesia care unit were significantly reduced in the ropivacaine group (p < 0.001 and p < 0.001, respectively), as well as the time to first mobilization (p < 0.001). CONCLUSION: Intra-operative systematic local infiltration analgesia reduces postoperative pain in patients undergoing vaginal hysterectomy, facilities mobilization and improves early recovery.

OBJECTIVE: To evaluate the analgesic effect of high-volume infiltration analgesia in urogenital prolapse surgery and provide a detailed description of the infiltration technique. DESIGN: A randomized, double-blind, placebo-controlled study following the CONSORT criteria. SETTING: A university hospital. PATIENTS: 48 patients undergoing posterior wall repair and perineorraphy. METHODS: Patients received high-volume (26 ml) ropivacaine 1% with epinephrine (n=23) or saline (n=22) infiltration using a systematic technique ensuring uniform delivery to all tissues incised, handled or instrumented during the procedure. MAIN OUTCOME MEASURES: Pain and opioid requirements were assessed for 24 hours as well as time spent in the post-anesthesia care unit and time to first mobilization. RESULTS: Pain at rest, during coughing and movement was significantly reduced for the first four hours with the high-volume local anesthetic infiltration technique (p<0.001-0.006). Opioid requirements and time spent in the post-anesthesia care unit were significantly reduced in the ropivacaine group (p<0.001 and p<0.001, respectively) as well as the time to first mobilization (p<0.014). CONCLUSION: Systematic high-volume infiltration analgesia is an effective analgesic technique in patients undergoing posterior wall repair and perineorraphy, and improves early recovery.
