Noninvasive Ventilation in the Prevention of Respiratory Dysfunction after Ventral Hernia Repair
Objective: to improve the treatment outcomes in patients after large ventral hernia repair, by reducing the incidence of respiratory dysfunction due to prophylactic constant positive airway pressure (CPAP).
Materials and methods. This investigation was conducted at the Luhansk state medical university in 2013–2014. The study enrolled 55 patients in accordance with the inclusion and exclusion criteria. Statistical analysis of the findings has been carried out using Statistica 6.0 package. After extubation in the intensive care unit, patients were divided into 2 groups — the control one and the group of prophylactic CPAP. Prophylactic CPAP with the level of 7–10 cmH2O has been used by sessions, during the first postoperative day.
Results. Prophylactic CPAP significantly improved indicators of arterial oxygenation and respiratory function. Pulmonary complications, including postoperative hypoxemia (when PaO2/FiO2 < 300) were less common in the group of CPAP. The duration of hospitalization in the intensive care unit was lower in the CPAP group, as compared with the control group. Thus, the prophylactic use of CPAP in the first postoperative day after ventral hernia repair had a positive effect on pulmonary gas exchange, respiratory function, treatment outcomes.
