Purpose: Alveolar collapse and pulmonary edema are main causes of postoperative pulmonary complications. Intrapulmonary ventilation(IPV) can increase functional residual capacity and lung compliance and improve ventilation/perfusion mismatch, resulting in improved arterial oxygenation. In this article, we studied the effects of IPV in patients on ventilatory support.
Materials and Methods: Twenty patients on postoperative ventilatory support were selected as subjects for this study. All patients were treated with IPV 3 times a day after intravenous injections of midazolam and vecuronium. Vital signs were checked, and arterial blood gas analyses were performed for three days.
Results: There were no statistical significance in systolic and diastolic pressures and heart rate. Arterial blood gas analyses revealed an increase in PaO2 from 97±25.8 mmHg to 134±39.9 mmHg and to 155±51.9mmHg on the 2nd and 3rd day, respectively. It also revealed a significant increase in PaO2/FiO2 from 204±85.1mmHg to 273±101.8mmHg and to 303±93.6mmHg on the 2nd and 3rd day respectively.
Conslusion: IPV improved arterial blood oxygenation without affecting vital signs, so it can be used as an effective treatment for postoperative pulmonary complications.
