This study was designed to determine the incidence of complications in a sample of 6,185 brachial artery punctures for arterial blood gas analysis.
The study sample was comprised of adult patients who had arterial blood gas analysis ordered in the course of their clinical evaluations in a multispecialty clinic and hospital affiliated with a university school of medicine. Subjects were entered prospectively at the time the procedure was done.
The overall incidence of all complications was 2.0%. Immediate limb pain or parenthesias occurred in 1.1%, while the onset of symptoms was delayed up to 24 h in 0.9%. Hematoma formation occurred in only 0.06%. None of the complications was considered to be of major impact, in that none was associated with limb ischemia or other objective abnormalities. Only one subject required analgesic medication to control pain that ultimately subsided spontaneously without deficit.
We believe that brachial artery puncture, when properly performed, is a safe and reliable alternative route for obtaining arterial blood for gas analysis.
本研究旨在确定6185例用于动脉血气分析的肱动脉穿刺样本中并发症的发生率。
研究样本包括在一所大学医学院附属的多专科诊所和医院接受临床评估期间进行动脉血气分析的成年患者。在进行该操作时前瞻性纳入受试者。
所有并发症的总体发生率为2.0%。1.1%的患者出现即刻肢体疼痛或感觉异常，而0.9%的患者症状出现延迟长达24小时。血肿形成仅占0.06%。所有并发症均未被认为具有重大影响，因为没有一种并发症与肢体缺血或其他客观异常相关。只有一名受试者需要使用止痛药物来控制疼痛，最终疼痛自行缓解且无功能缺损。
我们认为，正确进行肱动脉穿刺是获取动脉血进行血气分析的一种安全可靠的替代途径。
