Randomized Controlled Trial Comparative Study
Ultrasound-guided erector spinae plane block versus oblique subcostal transversus abdominis plane block for postoperative analgesia of adult patients undergoing laparoscopic cholecystectomy: Randomized, controlled trial.
Laparoscopic cholecystectomy (LC) is a frequently applied minimally invasive surgery. Intraoperative access is provided with small keyhole entries on the abdominal wall. However, LC causes moderate to severe postoperative pain. The subcostal approach of TAP block was described by Hebbard et al. for postoperative analgesia especially for upper abdominal surgeries. Ultrasound-guided erector spinae plane (US-ESP) block is a novel technique targeting ventral rami, dorsal rami and rami communicantes of the spinal nerves. ⋯ Ultrasound-guided ESP block reduced postoperative tramadol consumption and pain scores more effectively than OSTAP block after laparoscopic cholecystectomy surgery.

Randomized Controlled Trial Comparative Study
Comparison of ultrasound-guided transmuscular quadratus lumborum block catheter technique with surgical pre-peritoneal catheter for postoperative analgesia in abdominal surgery: a randomised controlled trial.
Following abdominal surgery, the provision of postoperative analgesia with local anaesthetic infusion through both transmuscular quadratus lumborum block and pre-peritoneal catheter have been described. This study compared these two methods of postoperative analgesia following laparotomy. Eighty-two patients 18-85 years of age scheduled to undergo elective surgery were randomly allocated to receive either transmuscular quadratus lumborum block or pre-peritoneal catheter block. ⋯ In the transmuscular quadratus lumborum group, there was a reduction in numerical rating score at rest (p = 0.036) and satisfaction scores on days 1 and 30 (p = 0.004, p = 0.006, respectively), but fentanyl usage was similar. In the transmuscular quadratus lumborum group, the highest and lowest blocks observed in the recovery area were T4 and L1, respectively. The transmuscular quadratus lumborum technique cost 574.64 Australian dollars more per patient than the pre-peritoneal catheter technique.

Randomized Controlled Trial Comparative Study
Comparison of the analgesic effect of an adductor canal block using a new suture-method catheter vs. standard perineural catheter vs. single-injection: a randomised, blinded, controlled study.
We performed a randomised, blinded, controlled study with adult patients scheduled for primary total knee arthroplasty under spinal anaesthesia. The aim was to investigate the analgesic effects of adductor canal block using catheter-based repeated boluses, either through a new suture-method catheter or a standard perineural catheter, compared with a single-injection technique. All patients received an adductor canal block after surgery with an initial bolus of 20 ml ropivacaine 0.75%, followed by 20 ml of ropivacaine 0.2% every 8 h in the standard and suture-method catheter groups, and sham boluses for the single-injection group. ⋯ On postoperative day 2, there were no differences between catheter groups, but muscle strength and ambulation were improved compared with the single-injection group. We conclude that providing repeated boluses via a catheter did not decrease opioid consumption or pain compared with a single injection, but improved muscle strength and ambulation on postoperative day 2. The two types of catheters were similar.

Meta AnalysisSystematic review and meta-analysis of single injection fascia iliaca blocks in the peri-operative management of patients with hip fractures.
The aim of the study was to determine the analgesic efficacy and safety profile of single injection fascia iliaca compartment block (FICB) performed peri-operatively for isolated hip fractures. ⋯ FICB is effective in controlling acute peri-operative pain in adult patients with traumatic hip fractures. The benefit is more evident during mobilization of the limb when compared to patients at rest.

To investigate, describe, and assess the phenomenon of "rebound pain" as a clinically relevant problem in anesthetic practice. ⋯ Rebound pain assessment should always be considered in clinical practice, as it is not a rare side effect of peripheral nerve blocks. There are still many challenging questions to be answered about rebound pain, so large prospective studies are needed to address the issue. For prevention, the use of peripheral nerve block techniques that avoid nerve damage and adequate perioperative analgesia associated with patient education on the early administration of analgesics, even during the period of analgesia provided by peripheral nerve block, is recommended. A better understanding of the "rebound pain" phenomenon, its pathophysiology, associated risk factors, and long-term consequences may help in developing more effective preventive strategies.
