Introduction: The three primary causes of compression and absorption atelectasis after general endotracheal anesthesia are dyskinesia, dyspnea and elevation in FIO2. General anesthesia eliminates the sigh reflex in all patients, resulting in atelectasis occurring rapidly. Alveolar recruitment maneuvers improve gas exchange, increase arterial oxygenation, and draw in collapsed alveoli. There is a wealth of literature supporting alveolar recruitment movements, and these days, mechanical ventilator settings include alveolar recruitment maneuvers. Our study's objective was to assess the effectiveness of alveolar recruitment techniques incorporated in the GE Healthcare Carestation 750.
Material and Methods: This evaluation covered all ASA I-III patients between the ages of 18 and 60 who were scheduled for general endotracheal anesthesia and did not have a history of cardiac or respiratory illness. Following tracheal intubation and the onset of general anesthesia, the patients were split into three groups: Group I - no intervention; Group II - single-step recruitment (pressure hold of 40mmHg for 20 seconds); Group III - multiple-step recruitment (Step I: Pinsp 30/PEEP 10; breathes 3; Step II: Pinsp 40/PEEP 10; breaths 3; Step III: Pinsp 50/PEEP 15; breaths 3). Changes in pulmonary compliance were the main result, and variations in PaO2 and PaO2/FIO2 were the secondary result. Analyses of arterial blood gas were taken both prior to and during the recruitment maneuver. A 50% FiO2 ratio was used.
Results: There were 75 patients in total for this evaluation. In contrast to the control groups, the alveolar recruitment maneuver groups exhibited greater pulmonary compliance (37% vs. 24% Group III vs. Group II). The groups that were also given alveolar recruitment strategies experienced an increase in intraoperative PaO2 (P<0.05). Compared to the control groups, PaO2/FIO2 rose in the alveolar recruitment maneuver groups. During or after the alveolar recruitment operations, none of the patients experienced any problems.
Conclusion: The individuals undergoing the alveolar recruitment maneuver groups had improved oxygenation.
