Randomized Controlled TrialComparison of continuous intravenous lidocaine versus transversus abdominis plane block for kidney transplant surgery: a randomized, non-inferiority trial.
Transversus abdominis plane (TAP) blocks are associated with an improvement in postoperative analgesia following kidney transplant surgery. However, these blocks carry inherent risk and require a degree of expertise to perform successfully. Continuous intravenous lidocaine may be an effective alternative. In this randomized, non-inferiority study, we hypothesized that a continuous lidocaine infusion provides similar postoperative analgesia to a TAP block. ⋯ This study demonstrates that a continuous infusion of lidocaine offers non-inferior postoperative analgesia compared with an ultrasound-guided unilateral, single-injection TAP block in the first 24 hours following kidney transplant surgery.

Randomized Controlled TrialPerineural dexamethasone reduces rebound pain after ropivacaine single injection interscalene block for arthroscopic shoulder surgery: a randomized controlled trial.
A single injection interscalene block (ISB) is a common regional analgesic technique in patients undergoing arthroscopic shoulder surgery. However, rebound pain after ISB resolution may reduce its overall benefit. Our primary aim was to assess whether perineural dexamethasone reduces the intensity and incidence of rebound pain in patients undergoing arthroscopic shoulder surgery under general anesthesia combined with a preoperative single injection ISB. ⋯ Perineural dexamethasone added to ISB using ropivacaine led to a much smoother resolution of ISB, reflected in a significantly smaller increase in pain after block resolution, a lower incidence of rebound pain and a lower sleep disturbance during the first postoperative week.

Randomized Controlled TrialPostoperative pain reduction by pre-emptive N-acetylcysteine: an exploratory randomized controlled clinical trial.
A new potential target for multimodal pain management is the group-II metabotropic glutamate receptor subtypes, which can be activated by N-acetylcysteine. We investigated whether pre-emptive administration of N-acetylcysteine leads to a reduction in postoperative pain after laparoscopic inguinal hernia repair. ⋯ Without finding important differences between N-acetylcysteine and placebo group in pain scores postoperatively, but with a high percentage of bothersome side effects for the N-acetylcysteine group, we would not recommend the use of pre-emptive intravenous N-acetylcysteine to reduce postoperative pain in laparoscopic inguinal hernia repair patients based on this study.
