The observation of success rate in intubating tenacious cored cannula into gas triccanal

目的观察在胃管腔内加用韧质内芯留置胃管的成功率。方法将57例患者按抽签法随机分成两组,插入韧质内芯留置胃管者30例为改良组,以常规方法留置胃管者27例为常规组。结果留置胃管一次成功率改良组为97%,常规组为37%,经χ2检验,χ2=26.35,P<0.01,有显著性差异。结论改良方法能提高留置胃管的一次成功率,尤其适用于意识障碍、气管切开及气管插管的患者。

Objective To observe success rate in intubating tenacious cored catheter into ga stric canal.Methods30of total57patients were randomly grouped as observational g roup receiving intubation of tenacious cored cannula into gastric canal and the rest27as the routine therapeutic group receiving indwelling catheter in routine way.Res ults The success rates for once intubation were97%and37%in the observati onal group and the routine therapeutic group respectively,t-test showed signific ant difference(÷ 2 =26.35,P<0.01).Conclus ion The intubation of tenacious cored cannula into ga stric canal can raise the success rate for once intu-bation.It is more adoptabl e for those patients in disorder of consciousness,with tracheotomy and with endo tracheal intubation.
