Abstract
Summary
Objective: To evaluate the efficacy of alveolar recruitment method on improvement of arterial oxygenation during general anesthesia. Subject and method: A randomized controlled clinical trial was divided into 2 groups of "intervention group" 45 patients and "control group" 37 patients. Method of mobilizing alveoli with a pressure of 40cmH2O for 40 seconds and maintaining a PEEP of 5cmH2O. Result: Mean of age of interventional group and control group were respectively 74.8 ± 8.4 and 76.4 ± 9.5. Mean of PaO2 at T2 (at a time after 5 minutes of final alveolar mobilization and completion of mechanical ventilation in both groups) in intervention group was 151.33 ± 25.94mmHg compare to 132.53 ± 36.08mmHg in control group. Mean of PaCO2 at T2 in interventional group and control group were respectively 39.12 ± 7.20mmHg and 38.21 ± 5.76mmHg; (p>0.05). The rate PaO2/FiO2 at T2 was 359.06 ± 62.84 vs 310.22 ± 71.74 in control group. And this great difference was significant with p=0.0012. Conclusion: “Alveolar Recruitment” improves effectly the arterial oxygenation during general anesthesia such as PaO2, PaCO2 and PaO2/FiO2, as well as there were no complications of resparitory and hemodynamic.
Keywords: Alveolar recruitment, abdominal surgery, blood gas.
