Although shoulder dystocia does not occur frequently the adverse effect to the patient and especially to infants can be catastrophic. The purpose of this study was to evaluate the incidence, the factors which may be related to or predispose to this condition and the consequence to the patients and their infants. All cases of shoulder dystocia which occurred during the fifteen year period from January 1982 to December 1996 were scrutinized. There were 17 cases of shoulder dystocia from a total of 109,923 deliveries giving the incidence of 1.6 per 10,000 deliveries. Of these 17 patients, 11 (65%) were delivered by vacuum extraction. Two patients had postpartum hemorrhage requiring blood transfusion. Infants' birthweights ranged between 3350 to 5160 grams. Erb's palsy occurred in 6 infants and all made full recovery subsequently.
虽然肩难产并不常见，但对患者尤其是对婴儿的不良影响可能是灾难性的。本研究的目的是评估其发生率、可能与该情况相关或易导致该情况的因素以及对患者及其婴儿的后果。对1982年1月至1996年12月这15年期间发生的所有肩难产病例进行了仔细审查。在总共109,923例分娩中，有17例肩难产，发生率为每10,000例分娩中有1.6例。在这17名患者中，11例（65%）通过真空吸引分娩。两名患者产后出血需要输血。婴儿出生体重在3350克至5160克之间。6名婴儿发生了臂丛神经麻痹，随后均完全康复。
