Abstract
The study was conducted to evaluate the effect of alveolar recruitment maneuvers during intra operative mechanical ventilation. Forty patients of ASA I and II, posted for elective laparotomies were randomly allocated into two groups. In the study group, high positive end expiratory pressures for specified number of breaths were used to increase the peak inspiratory pressures. This increased airway pressure recruited the atelectatic alveoli .The recruited alveoli were prevented from collapsing by a baseline positive end expiratory pressure and repeated recruitment at regular intervals. No such recruitment strategies were employed in the control group. Proximal airway pressures and dynamic compliance significantly increased in the study group. (p <0.05). A significant increase in the arterial oxygen content was observed at 60 min in the study group. (PaO2/FiO2 ratio 581.05). But in the recovery room, the PaO2/FiO2 ratios in both the groups were comparable to the baseline. Hence, recruitment maneuvers increased the intra operative arterial oxygen content with not much effect in the post-operative period. CONCLUSION: General anesthesia comes hand in hand with atelectasis. Prevention of atelectasis not only increases arterial oxygenation but also reduces associated complications. This study concluded that alveolar recruitment maneuver significantly increased intra operative arterial oxygenation, which might be beneficial in preventing pulmonary complications and surgical site infections in the post-operative period.
