| 目的：观察预氧合在ICU 重症患者急救插管中的效果并探讨预氧合的最佳方式。方法：选择ICU内低氧血症成年危重患者
28 例，按入ICU顺序随机分为3 组：A 组（对照组，n=10），B 组（气囊- 面罩预氧合组, n=9）和C 组（麻醉机- 面罩预氧合组，n=9）。
A 组入室后即行快速气管插管，B 组气囊- 面罩预氧合5 min 后行气管插管，氧流量为15 L/min。C 组麻醉机- 面罩预氧合5 min
后行气管插管，氧流量为4 L/min。观察指标：持续脉搏血氧饱和度（SpO2），动脉血气分析及相关并发症。结果：三组在预氧合之前，
各项基本指标比较无统计学差异。在预氧合后，B、C组的SpO2明显高于A 组（P<0.05）；在插管后即刻，B、C组的SpO2也显著高
于A组（P<0.05），同时C 组SpO2高于B 组（P<0.05）。血气分析中，预氧合后，C 组的PaO2和SaO2均高于A、B 组（P<0.05）；在插
管后即刻，C 组PaO2和SaO2高于A 组，同时C组SaO2高于B 组（P<0.05）。并发症的比较上，C 组的腹胀发生率明显低于B 组
（P<0.05）。结论：ICU 内急救插管前的预氧合能显著提高患者的血氧水平，效果明显好于直接气管插管；在预氧合的方式中，麻醉
机-面罩的预氧合效果要优于常规使用的气囊- 面罩，且并发症也较少。 |

| Objective:To determine the effectiveness of preoxygenation for emergency tracheal intubation in critically ill patients
and to find out the better preoxygenation method.Methods:Prospective randomized study was performed in intensive care unit (ICU).
Twenty-eight hypoxemic critically ill patients were randomly assigned into 3 groups: group A (control group, n=10), group B (bag-valvemask
preoxygenation group, n=9) and groupC (anesthesia machine ventilator preoxygenation group, n=9). Standardized rapid sequence
intubation was performed without preoxygenation in group A; Preoxygenation was performed by using a bag-valve-mask driven by 15
L/min oxygen before a rapid sequence intubation in group B; Preoxygenation was performed by using anesthesia machine ventilator
through a face mask driven by 4 L/min oxygen before a rapid sequence intubation in group C. Tracheal intubation were performed after
5min preoxygenation in groups B and C. Pulseoximetry (SpO2), arterial blood gases and complications were observed.Results:The three
groups were similar in terms of age, gender , AⅡand arterial blood gases before preoxygenation. At the end of preoxygenation, SpO2 was
higher in the group B and C as compared with group A（P<0.05）. After the intubation procedure, SpO2 values observed in group B and C
were also higher than that in group A（P<0.05）, and group C was better than group B（P<0.05）. In arterial blood gases analysis, PaO2 and
SaO2 values observed were better in the group C as compared with group A and B after preoxygenation （P<0.05）. And after the
intubation procedure, PaO2 and SaO2 value were still better in the group C as compared with group A（P<0.05）, SaO2 value was better in
the group C than the group B（P<0.05）. Regurgitations were observed with significant difference between B and C groups（P<0.05）Conclusion:For emergency tracheal intubation in critically ill patients in the ICU, preoxygenation is more effective than the rapid
sequence intubation without preoxygenation in improving oxygenation indicators. Preoxygenation by the anesthesia machine is more
effective than the bag-valve- mask. |
