Randomized Controlled Trial
Evaluation of surgical conditions during laparoscopic surgery in patients with moderate vs deep neuromuscular block.
The routine use of neuromuscular blocking agents reduces the occurrence of unacceptable surgical conditions. In some surgeries, such as retroperitoneal laparoscopies, deep neuromuscular block (NMB) may further improve surgical conditions compared with moderate NMB. In this study, the effect of deep NMB on surgical conditions was assessed. ⋯ Application of the five-point SRS showed that deep NMB results in an improved quality of surgical conditions compared with moderate block in retroperitoneal laparoscopies, without compromise to the patients' peri- and postoperative cardiorespiratory conditions. Trial registration The study was registered at clinicaltrials.gov under number NCT01361149.

Review Meta Analysis
Effects of dexamethasone as a local anaesthetic adjuvant for brachial plexus block: a systematic review and meta-analysis of randomized trials.
Adjuvant perineural dexamethasone (4-10 mg) prolongs brachial plexus sensory and motor blockade by between 65% and 100% longer.
