止血器用于监护室昏迷患者桡动脉采血后按压止血的安全性及有效性观察

Observation on the Safety and Effectiveness of Tourniquet Compression Applied to Coma Patients in ICU after Radial Artery Blood Collection

目的:探讨止血器用于监护室昏迷患者桡动脉采血后按压止血的安全性及有效性,减轻患者动脉采血后淤斑发生率,节省护士按压时间。方法:对监护室昏迷患者88例进行自身对照研究,单日动脉采血后采用常规按压法,双日动脉采血后采用止血器按压法,比较2种按压方法的瘀斑发生率。结果:常规按压法瘀斑阳性率为24.8%,止血器按压法为12.1%,两者相比具有显著差异(P<0.05)。结论:动脉采血后止血器按压法有效降低了监护室昏迷患者淤斑发生率,止血效果优于常规按压法,并节省了护士的按压时间。

Objective： To explore the safety and effectiveness of tourniquet applied to coma patients in ICU after radial artery blood collection, reduce petechia incidence after drawing blood from radial artery of the patients and save compression time of the nurses. Methods： Eighty-eight patients were investigated by self-control study, in odd-numbered days they adopted conventional pressing method after blood collection, in even-numbered days they used tourniquet compression method, petechia incidence in the patients were compared after they used two different pressing methods. Results： Petechia positive incidence of conventional pressing method was 24.8%, higher than12.1% of tourniquet compression method, the comparison had significant difference（P〈0.05）. Conclusion： Tourniquet compression method could effectively decrease petechia incidence of ICU coma patients after blood collection,it could obtain better effects compared with conventional pressing method and save compression time of the nurses.
