Summary: | The atelectasis during anesthesia affects gas exchange in humans and animals; this can be corrected using alveo-lar recruitment maneuvers (MRA). This study evaluated the effect of two cyclic alveolar recruitment protocols by increas-ing the positive end expiratory pressure (PEEP) on six param-eters of arterial blood gases in 28 anesthetized bitches. The animals were randomly distributed into two groups accord-ing to the alveolar recruitment maneuver (MRA) to perform; Group 1: Maneuver 1 (M1) recruited with PEEP of 10cmH2O and group 2: Maneuver 2 (M2) with PEEP 20cmH2O recruit-ed with 20 cmH2O PEEP. Cyclic maneuvers were performed using ambulatory manual breathing units (AMBU). The PaO2, PaCO2, TCO2, PaO2/ FiO2, SpO2 y CaO2 values wasanalyzed for each MRA in four times; T1 (baseline in preanesthesia), T2 (before of the recruitment), T3 (30 minutes after maneu-ver) and T4 (24 hours after maneuver). In the T2 moment the PaO2, PaCO2, TCO2, SpO2 andCaO2 values showed a significant increase (p<0.05) from T1 baseline moment. No significant changes were apparent after performing each ma-neuver in the time T3 of evaluation; however, there was a significant increase (p <0.05) in PaO2 of 13.5% in the time T4 after making the M2 maneuver. From which we conclude that the performance of alveolar recruitment maneuvers by artificial manual breathing units - AMBU are a safe alternative to assisted ventilation during alveolar recruitment maneuvers with PEEP lower than 20cmH2O in clinically healthy animals. |
