硬膜外镇痛下Cook宫颈扩张球囊在足月引产中的作用

Effects of Cook balloon cervical dilator on full-term nulliparous parturients under epidural analgesia

2013年9月至2015年2月对40例超预产期、单胎头位孕妇在硬膜外镇痛下使用Cook球囊引产（观察组），与40例未实施硬膜外镇痛Cook宫颈扩张球囊引产孕妇（对照组）比较。观察组第一产程潜伏期明显短于对照组[（198．7±65．7）与（242．9±78．9）min，P〈0．05]，剖宫产率和会阴裂伤率降低（分别为8％与45％，对照组分别为15％和5％），且分娩较为舒适，不影响引产成功率（均为98％），外周血白细胞计数引产前后观察组分别为（8．82±2．74）×10^9／f．和（9．10±3．06）×10^9／L，CRP水平分别为（4．73±0．87）和（4．82±0．90）mg／L。说明硬膜外镇痛下Cook宫颈扩张球囊在足月引产中能明显缩短第一产程，减轻产妇痛苦，不增加感染机会和并发症，安全、有效。

To explore the feasibility and effects of Cook balloon cervical dilator on full-term nulliparous parturients under epidural analgesia. The observation group （ n = 40 ） received Cook balloon cervical dilation under epidural analgesia. However, the control group （ n = 40） had no epidural analgesia. Latent phase of labor was shorter in observation group than that in control group [ （ 198.7 ± 65.7 ） vs. （242.9±78.9） min, P 〈0.05]. And the incidence of cesarean section and perineal laceration was lower under epidural analgesia（8% vs. 15% , 45% vs. 50% respectively）. There were no effects on success rate of induced labor in neither group. Cook balloon could shorten latent phase of labor, relieve the pain of parturients and increase no infection rate [leukocyte count： （8.82 ±2.74） × 10^9/L vs. （9.10 ±3.06）×10^9/L, C-reactive protein： （4.73±0.87） mg/L vs. （4.82 ±0.90） mg/L respectively]. It is worth wider clinical popularization.
