Abstract
Aim: During rapid sequence intubation (RSI), the O 2 reserve limits the intubation duration. The study objective was to examine the impact of RSI on arterial blood gases (ABG) during the preoxygenation phase. Methods: This open, prospective clinical study examined samples of patients who had endotracheal intubation (ETI) as RSI between March 2014 and September 2014 in our emergency department. The variations in ABG PaO 2 and PaCO 2 before and after preoxygenation and after intubation were examined and compared with demographic and clinical variables. Results : The study included 67 patients (46 male, 21 female) with a mean age of 69.9 years. SBP, DBP, and MABP decreased, while pulse rate and SpO 2 increased. No difference was observed between PaO 2 values and demographic and clinical variables; however, a statistically significant relationship was found between the difference (Δ) between PaO 2 values measured after endotracheal tracheal intubation (ETI) and after preoxygenation and the ABG SpO 2 and the SpO 2 classification before preoxygenation. Conclusion: The relationship between SpO 2 and its classification following ETI and increased ABG SpO 2 was statistically significant. Our real-life study emphasises that deciding on intubation without desaturating patients could have positive effects on intubation success. Regardless, increasing SpO 2 prior to ETI will contribute positively to the O 2 reserve by the end of ETI. The ΔPaO 2 , before and after preoxygenation, was not affected by age; gender; body mass index (BMI) and its classification; GCSS; vital signs and ABG findings gathered before preoxygenation; respiration rate (RR) during preoxygenation; preoxygenation duration; oral air passage usage or air leakage.
