Randomized Controlled Trial
A randomized comparison between neurostimulation and ultrasound-guided lateral femoral cutaneous nerve block.
This prospective, randomized trial compared neurostimulation (NS) and ultrasound (US) guided lateral femoral cutaneous nerve (LFCN) block. We hypothesized that US would result in a shorter total anesthesia-related time (sum of performance and onset times). ⋯ Ultrasound guidance and NS provide similar success rates and total anesthesia-related times for LFCN block. The territory of the LFCN displays wide inter- and intra-individual variability.

To determine whether mandatory psychiatric admission laboratory tests yield results that change the disposition of a patient with primary psychiatric complaint from admission to a psychiatric service to admission to a medical service. ⋯ Patients presenting to the emergency department with a psychiatric chief complaint and no physical complaints, abnormal vital signs, or abnormal physical exam findings have less than 1% probability that an abnormal laboratory study will change their disposition from a psychiatric admission to a medical admission.
