Hypoxemia may occur during rapid sequence intubation (RSI). This study establishes the incidence of this adverse event in patients intubated by physicians in a helicopter emergency service in Norway.
This was a prospective, observational study of all RSIs performed by helicopter emergency service physicians during a 12-month period. Hypoxemia was defined as a decrease in Spo(2) values to below 90% or a decrease of more than 10% if the initial Spo(2) was less than 90%.
A total of 122 prehospital intubations were performed during the study period. Spo(2) data were available for 101 (82.8%) patients. Hypoxemia was present in 11 (10.9%) patients.
Prehospital, RSI-related hypoxemia rates in this study are lower than reported rates in similar studies and are comparable with in-hospital rates. Prehospital RSI may accordingly be considered a safe procedure when performed by experienced physicians with appropriate field training.
在快速序贯诱导插管（RSI）期间可能会发生低氧血症。本研究旨在确定挪威直升机急救服务中医生插管患者的这一不良事件的发生率。
这是一项前瞻性、观察性研究，对直升机急救服务医生在 12 个月期间进行的所有 RSI 进行了研究。低氧血症定义为 Spo2 值下降到 90%以下，或者如果初始 Spo2 值低于 90%，则下降超过 10%。
研究期间共进行了 122 例院前插管。101 例（82.8%）患者有 Spo2 数据。11 例（10.9%）患者存在低氧血症。
与类似研究报道的发生率相比，本研究中院前、RSI 相关的低氧血症发生率较低，与院内发生率相当。因此，当由具有适当现场培训经验的医生进行时，院前 RSI 可被视为一种安全的程序。
