Delayed retroperitoneal haematoma after failed lumbar plexus block.

abstract：BACKGROUND:Investigators planning dose-response studies of neuromuscular blockers have rarely used a priori power analysis to determine the minimal sample size their protocols require. Institutional Review Boards and peer-reviewed journals now generally ask for this information. This study outlines a proposed method fo...
