The objective of the study was to examine the trends in the rate of peripartum hysterectomy and the contribution of changes in maternal characteristics to these trends.
This was a cross-sectional study of peripartum hysterectomy identified from hospitalizations for delivery recorded in the 1994-2007 Nationwide Inpatient Sample.
The overall rate of peripartum hysterectomy increased by 15% during the study period. The rate of hysterectomy for abnormal placentation increased by 1.2-fold; adjustment for previous cesarean delivery explained nearly all of this increase. The rate of hysterectomy for uterine atony following repeat cesarean delivery increased nearly 4-fold, following primary cesarean delivery approximately 2.5-fold, and following vaginal delivery about 1.5-fold. This fast growing trend in peripartum hysterectomy secondary to uterine atony was also largely explained by increasing rates of primary and repeat cesareans.
Rates of peripartum hysterectomy increased substantially in the United States from 1994 to 2007; much of this increase was due to rising rates of cesarean delivery.
本研究旨在探讨围生期子宫切除术的发生率趋势,以及产妇特征变化对这些趋势的影响。
这是一项横断面研究,对 1994 年至 2007 年全美住院分娩记录中识别出的围生期子宫切除术进行了研究。
研究期间,围生期子宫切除术的总体发生率增加了 15%。胎盘异常所致子宫切除术的发生率增加了 1.2 倍;调整剖宫产既往史可解释这一增加的大部分原因。再次剖宫产术后、初次剖宫产术后和阴道分娩后因宫缩乏力导致的子宫切除术的发生率分别增加了近 4 倍、约 2.5 倍和 1.5 倍。由于原发性和重复剖宫产率的增加,宫缩乏力导致的围生期子宫切除术的这一快速增长趋势也在很大程度上得到了解释。
1994 年至 2007 年,美国围生期子宫切除术的发生率大幅上升;这一上升主要归因于剖宫产率的上升。
