Randomized Controlled Trial
The impact of ultrasound-guided transmuscular quadratus lumborum block combined with local infiltration analgesia for arthroplasty on postoperative pain relief.
This study aimed to evaluate the efficacy of ultrasound-guided transmuscular quadratus lumborum block (QLB) combined with local infiltration analgesia (LIA) for pain management and recovery in patients who have undergone total hip arthroplasty (THA) via a posterolateral approach. ⋯ Compared to treatment with LIA alone, ultrasound-guided transmuscular QLB combined with LIA can provide better postoperative pain relief and enhance the recovery of THA patients, since it does not cause quadriceps femoris muscle weakness and is associated with significantly lower need for intraoperative opioids.

Observational StudyOpening injection pressure monitoring using an in-line device does not prevent intraneural injection in an isolated nerve model.
Injection pressure monitoring using in-line devices is affordable and easy to implement into a regional anesthesia practice. However, solid evidence regarding their performance is lacking. We aimed to evaluate if opening injection pressure (OIP), measured with a disposable in-line pressure monitor, can prevent intraneural (subepineural) injection using 15 pound per square inch (PSI) as the reference safety threshold. ⋯ Our results suggest that in-line pressure monitoring may not prevent intraneural injection using an injection pressure of 15 PSI as reference threshold. Due to the preliminary nature of our study, further evidence is needed to demonstrate clinical relevance.

Randomized Controlled TrialComparison of the analgesic effects of two quadratus lumborum blocks (QLBs), QLB type II vs. QLB type III, in Cesarean Delivery: A randomised study.
Quadratus lumborum blocks (QLBs) are relatively novel regional anaesthesia techniques, and the efficacy of all three types of QLB for postoperative analgesia in caesarean delivery (CD) has been demonstrated in separate studies. The aim of the present study is to compare the analgesic efficacy of the QLB-II and QLB-III blocks performed at the end of surgery in patients undergoing spinal anaesthesia for CD. ⋯ The analgesic efficacy of QLB-III was superior to QLB-II in patients who had undergone CD under spinal anaesthesia without use of intrathecal opioids and nonsteroidal anti-inflammatory drugs.

Blocking the suprascapular nerve under the inferior belly of the omohyoid muscle is a novel regional anesthesia technique that has been proposed for shoulder analgesia. We describe the use of and our experience with bilateral indwelling suprascapular catheters for pain management via continuous infusions in a patient undergoing bilateral shoulder surgery. ⋯ Judicious use of preoperatively placed bilateral suprascapular catheters added to a comprehensive multimodal analgesic regimen provided excellent analgesia without respiratory compromise throughout the perioperative course.
