Occurrence of the carpal tunnel syndrome in pregnancy was studied by examining 100 consecutive obstetric admissions. Twenty-one patients reported paresthesias or hypesthesia in the median nerve sensory distribution of the hand during the pregnancy; eight of these had decreased sensation subjectively at the time of examination one to three days after delivery; two had trophic changes, loss of sudomotor function, thenar atrophy, and decreased two-point discrimination; and one had a delay in motor conduction time across the carpal tunnel. Of the 21 patients, 18 became asymptomatic before or shortly after delivery. The remaining three were asymptomatic three months after delivery. We conclude that the incidence of symptoms is probably greater than usually appreciated, but that few patients require treatment. Steroid injection may occassionally be necessary, but the need for surgical intervention is rare.
通过检查100例连续产科入院患者，研究了妊娠期间腕管综合征的发生情况。21例患者在妊娠期间报告手部正中神经感觉分布区有感觉异常或感觉减退；其中8例在产后1至3天检查时主观感觉减退；2例有营养性改变、汗腺运动功能丧失、鱼际肌萎缩和两点辨别觉减退；1例腕管运动传导时间延迟。在这21例患者中，18例在分娩前或分娩后不久症状消失。其余3例在产后3个月无症状。我们得出结论，症状的发生率可能比通常认为的要高，但很少有患者需要治疗。偶尔可能需要注射类固醇，但很少需要手术干预。
