Randomized Controlled Trial
The analgesic efficacy of ultrasound-guided transversus abdominis plane (TAP) block combined with oral multimodal analgesia in comparison with oral multimodal analgesia after caesarean delivery: a randomized controlled trial.
The transversus abdominis plane (TAP) block is used increasingly in parturients after caesarean delivery. This is a randomized controlled trial to evaluate the effectiveness of bilateral single-shot of TAP blocks in patients who received multimodal oral analgesia for postoperative pain relief. ⋯ Bilateral single-shot of TAP blocks confer little additional benefit when a multimodal oral analgesic regimen is used for pain control after caesarean section under spinal anaesthesia.

Background and objectives: The fixed-rate continuous background infusion mode with bolus dosing is a common modality for intravenous patient-controlled analgesia (PCA). However, some patients suffer from inadequate analgesia or opioid-related adverse effects due to the biphasic pattern of postoperative pain. Therefore, we investigated the postoperative analgesic efficacy of PCA using an optimizing background infusion mode (OBIM) where the background injection rate varies depending on the patient's bolus demand. ⋯ The total cumulative opioid dose in fentanyl equivalents, after converting sufentanil to fentanyl using an equipotential dose ratio, was lower in group OBIM (714.1 (647.4-780.9) μg) than in group TBIM (963.7 (870.5-1056.9) μg); p < 0.001). The background infusion rate was significantly different between groups throughout the study period (p < 0.001); it was higher in group OBIM than in group TBIM before the 12th postoperative hour and lower from the 18th to the 48th postoperative hour. Conclusions: The OBIM combined with bolus dosing reduces the cumulative PCA volume and opioid consumption compared to the TBIM combined with bolus dosing, while yielding comparable postoperative analgesia and bolus demand in patients undergoing laparoscopic cholecystectomy.

Quadriceps Weakness After Single-Shot Adductor Canal Block: A Multivariate Analysis of 1,083 Primary Total Knee Arthroplasties.
Adductor canal blocks (ACBs) are commonly employed in multimodal pain control for total knee arthroplasty (TKA) and minimize motor blockade compared with femoral nerve blocks. Quadriceps weakness may be associated with ACBs. The purpose of this study was to quantify the prevalence of clinically relevant quadriceps weakness after a single-shot ACB and to identify the factors that are associated with its diagnosis. ⋯ Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Efficacy of intravenous lidocaine infusions for pain relief in children undergoing laparoscopic appendectomy: a randomized controlled trial.
Intravenous lidocaine, a potent local anesthetic with analgesic and anti-inflammatory properties, has been shown to be an effective adjunct that reduces intra- and postoperative opioid consumption and facilitates pain management in adults. While it shows promise for use in the pediatric population, limited evidence is available.

Impact of a multimodal analgesic protocol modification on opioid consumption after cesarean delivery: a retrospective cohort study.
Adequate pain control is a mainstay in enhanced recovery after surgery (ERAS) protocols. ERAS protocols are widely accepted in colorectal and gynecologic surgeries and are increasingly implemented in the obstetric setting. Multimodal analgesia incorporating non-steroidal anti-inflammatory drugs (NSAIDs) and acetaminophen is a mainstay of ERAS protocols for cesarean delivery, but little research has focused on the choice of NSAIDs or timing of initiation in women undergoing cesarean delivery. At our institution, patients undergoing cesarean delivery receive a standardized multimodal analgesic regimen consisting of neuraxial morphine with NSAIDs and acetaminophen. Our initial protocol involved starting the oral analgesics in the recovery room. There was variability in whether these medications were given in a timely manner or withheld in the setting of postoperative nausea and vomiting. We modified this protocol and performed a retrospective analysis to assess the impact of this change on postoperative opioid rescue requirements in women undergoing cesarean delivery under neuraxial anesthesia. ⋯ There was a significant decrease in the need for and the dose of rescue opioid medications with the new protocol. This highlights the importance of optimizing the choice of agents, as well as route and timing of administration of the components of the postoperative multimodal analgesic regimen.
