聚氨酯海绵塞条引产时宫颈管厌氧菌培养

Culture of Anaerobes in Labour Induction with Polyurethane Tent

30例晚期妊娠产妇应用聚氨酯海棉塞条(以下简称塞条)引产。为了解塞条引产的安全性,在放置塞条前后取宫颈管粘液作厌氧菌培养。实验结果:8例于放置塞条前后均未检出厌氧菌;检出厌氧菌的22例中,18例放置塞条前后检出的菌种一致,没有因放置塞条引起新的厌氧菌感染,余4例在放置塞条后虽出现了菌种不一致,然而。新菌种均为低毒力或条件性致病菌,无一例检出产气荚膜梭菌。临床上本组无一例发生产时或产后感染。作者认为在严格无菌条件下应用聚氨酯海棉塞条引产是安全的。

In order to test the safety of induction of labour with polyurethane tent, 30 cases were studied. Before and after insertion of the tent, cervical mucus samples were collected and cultured for anaerobes. The study showed that no bacturia were cultured in 8 patients and positive cultures were obtained in 22 patients, a detection rate of 73.33%. 18 out of the 22 cases had the same bacteria, while 4 had different ones before and after insertion of the tent. So in 26 cases (86.67%)no new bacterial growth was induced the insertion of the tent. 4 cases had new growth of bacteria that were all of tow toxicity. No C-perfringens were found, nor did clinical inflammation occur. Therefore, the polyurethane tent is a safe method for induction of labour.
