目的应用足背动脉穿刺法采集危重患者血气,并分析足背动脉穿刺法的临床效果。方法选择天津市南开医院急诊科在2013年4月-2014年4月收治的共80例危重症患者,采用足背动脉穿刺法行血气分析。结果在选取的80例患者中,经足背动脉穿刺法,穿刺成功共有77例,成功率为96.25%,均采集动脉血。有3例失败,原因为患者下肢功能障碍和发生了皮下出血,因此采用其他部位进行穿刺。结论患者的足背动脉易暴露,穿刺过程中操作方便并且周围软组织少,相比其他血气分析穿刺法效果更佳,护理人员易于观察及确定穿刺点,穿刺成功率较高,保护患者隐私确保穿刺的安全性,既准确无误又及时采集血气分析标本,可计划性保护动脉。
Objective To apply the dorsalis pedis artery puncture method to collect blood gas in critically ill patients and analyze the clinical effect of dorsalis pedis artery puncture. Methods A total of 80 critically ill patients admitted to the Emergency Department of Nankai Hospital of Tianjin from April 2013 to April 2014 were enrolled in this study. Blood gas analysis was performed using the dorsalis pedis artery puncture. Results In the selected 80 patients, by the dorsalis pedis puncture, a total of 77 cases of successful puncture, the success rate was 96.25%, were collected arterial blood. Three patients failed because of lower extremity dysfunction and subcutaneous hemorrhage in the patient, so other sites were used for puncture. Conclusions The dorsalis pedis artery of the patients is easy to be exposed, the operation is convenient and the surrounding soft tissue is less in the process of puncture, which is more effective than other blood gas analysis puncturing methods. Nurses can easily observe and determine the puncture point, and the success rate of puncture is high, so as to protect the privacy of patients. The safety of both accurate and timely collection of blood gas samples can be planned to protect the artery.
