Single-Shot Lumbar Erector Spinae Plane Block in Total Hip Replacement: A Randomized Clinical Trial.

Background: Lumbar erector spinae plane block (ESPB) has been proposed to relieve pain after total hip replacement (THR), but high-quality evidence is scarce.

Methods: This double-blinded (patient and assessor) randomized clinical trial, performed in 2 tertiary centers in Hong Kong, recruited patients undergoing primary unilateral THR under general anesthesia (GA) who received either single-shot ESPB at L1 (treatment arm) or no block (control arm). Patients were followed up on the first day postoperatively.

Attitudes, knowledge, and actions with regard to organ donation among Hong Kong medical students.

Objective: To study attitudes, knowledge, and actions of local medical students with regard to organ donation and self-perceived confidence and competence in approaching potential organ donors.

Design: Cross-sectional questionnaire survey.

Setting: Faculty of Medicine, The University of Hong Kong, Hong Kong.
