Posterior arm delivery versus the shoulder shrug maneuver in shoulder dystocia management: A simulation-based comparative study.

ABSTRACT:

Objective

To compare posterior arm delivery and the shoulder shrug maneuver in shoulder dystocia.

Methods

A prospective, randomized, simulation-based experimental study was conducted with six physicians managing 96 simulated shoulder dystocia cases. Participants included three obstetricians with more than 15 years of experience and three trainees. Variables collected included perineal pressure, maneuver time, simulated humeral fractures, first-attempt success, and perceived difficulty.

Results

Posterior arm delivery exerted significantly less maximum perineal pressure than the shoulder shrug maneuver (median 12.5 mm Hg, interquartile range (IQR) 7.0-22.5 mm Hg versus median 22.0, IQR 13.0-37.0 mm Hg; P = 0.002). Obstetricians with greater experience applied less perin
