选择我科收治的结核性脑膜炎机械通气患者60例,随机分为观察组(密闭式吸痰组)30例和对照组(开放式吸痰组)30例,观察记录两组患者吸痰前及吸痰后2min HR、SPO2及吸痰时间(t)的变化。采用密闭式吸痰组患者前后的SPO2、HR值无显著变化,无痰液外喷,吸痰时间更短(≤2min),常规对照组吸痰后SPO2降低、HR增快、吸痰时间更长(>2min),明显有痰液外喷。密闭式吸痰管对结核性脑膜炎机械通气患者吸痰前后HR、SPO2值无显著变化,吸痰时间更短,无痰液外喷现象,可防止发生交叉感染。
Sixty patients with tuberculous meningitis and mechanical ventilation were selected and randomly divided into observation group (closed suction group) 30 cases and control group (open suction group) 30 cases. And HR, SPO2 and suctioning time (t) 2min after sputum aspiration. There was no significant change in SPO2 and HR before and after treatment in closed suction group, no sputum spraying, shorter suction suction time (≤2min), lower SPO2 after suctioning in conventional control group, faster HR, longer suction time Long (> 2min), there is obviously sputum spray. Closed suction tube tuberculous meningitis patients with mechanical ventilation before and after suctioning HR, SPO2 value no significant change, shorter suction suction time, no sputum spray phenomenon to prevent the occurrence of cross-infection.
