To quantify the occurrence of arterial hypotension and arterial oxygen desaturation in a series of patients with head trauma rescued by helicopter.
Prospective, observational study.
Arterial HbO2 was measured before tracheal intubation at the accident scene in 49 consecutive patients with head injuries. Arterial pressure was measured using a sphygmomanometer.
Mean arterial saturation was 81% (SD 24.24); mean arterial systolic pressure was 112 mm Hg (SD 37.25). Airway obstruction was detected in 22 cases. Twenty-seven patients showed an arterial saturation lower than 90% on the scene, and 12 had a systolic arterial pressure of less than 100 mm Hg. The outcome was significantly worse in cases of hypotension, desaturation, or both.
Hypoxemia and shock are frequent findings on patients at the accident scene. Hypoxemia is more frequently detected and promptly corrected, white arterial hypotension is more difficult to control. Both insults may have a significant impact on outcome.
量化一系列由直升机救援的头部创伤患者中动脉低血压和动脉血氧饱和度降低的发生率。
前瞻性观察性研究。
对49例连续头部受伤患者在事故现场气管插管前测量动脉血红蛋白氧饱和度。使用血压计测量动脉压。
平均动脉饱和度为81%（标准差24.24）；平均动脉收缩压为112mmHg（标准差37.25）。22例检测到气道阻塞。27例患者在现场动脉饱和度低于90%，12例收缩动脉压低于100mmHg。低血压、饱和度降低或两者兼有的情况下，预后明显更差。
低氧血症和休克在事故现场患者中很常见。低氧血症更常被检测到并能迅速纠正，而动脉低血压更难控制。这两种损伤都可能对预后产生重大影响。
