Randomized Controlled Trial
Transversus abdominis plane block versus quadratus lumborum block type 2 for analgesia in renal transplantation: A randomised trial.
Several studies have shown an analgesic efficacy of a transversus abdominis plane block (TAPB) in reducing opioid requirements during and after cadaveric renal transplantation surgery, but the effect of a quadratus lumborum block (QLB) in this type of surgery is unclear. ⋯ The reduction of fentanyl consumption in the first 24 h after renal transplantation with no difference in pain intensity and patient satisfaction shows a beneficial effect of one-sided QLB type 2 over a one-sided TAPB in regards to postoperative analgesia. However, the reduction in opioid consumption did not affect the frequency of opioid-related adverse effects.

Randomized Controlled Trial
Effects of adding a combined femoral and sciatic nerve block with levobupivacaine and clonidine to general anaesthesia in femoropopliteal bypass surgery: A randomised, double-blind, controlled trial.
Adding a regional block to general anaesthesia can prevent postoperative pain and improve peripheral circulation. ⋯ Combining the two regional blocks improves the quality of postoperative care in this frail population, probably by reducing the amount of peri-operative opioid.

Randomized Controlled Trial
Dislocation rates of perineural catheters placed either perpendicular or parallel to the femoral nerve: A randomised controlled trial.
Ultrasound has increased the efficacy of femoral nerve catheters but their postoperative dislocation still remains a common problem. Although catheter placement parallel to the nerve seems to reduce dislocation rates in other nerves and plexuses, the possible advantage for femoral nerve catheter placement remains unclear. ⋯ Rotating the ultrasound probe to the long-axis in-plane view enabled examination of the catheter position when it was placed parallel to the nerve. The parallel placement of the catheter required more time, but did not significantly improve dislocation rate, pain scores or sensory blockade.
