BackgroundPatients undergoing abdominal wall reconstruction are at risk of developing major postoperative respiratory complications. The authors attempted to identify factors predictive of respiratory complications following abdominal wall reconstruction.MethodsAll patients who underwent complex abdominal wall reconstruction over a 2-year period were reviewed. The primary endpoint studied was severe respiratory complication, defined as respiratory insufficiency requiring intubation or transfer to a higher level of care.ResultsSixty patients underwent complex abdominal wall reconstruction during the study period. The incidence of respiratory complications was 20 percent. Factors predictive of postoperative respiratory complication included age (p = 0.05), American Society of Anesthesiologists score (p = 0.04), and hernia defect size (p = 0.01). In addition, patients who developed respiratory complications were more likely to have had a greater change in plateau pressure (5.8 versus 2.3 cmH(2)O; p = 0.01). The greater the change in plateau pressure, the greater the risk of developing a respiratory complication: for a change in plateau pressure greater than or equal to 6 cmH(2)O, the odds ratio was 8.67; for a change in plateau pressure greater than or equal to 9 cmH(2)O, the odds ratio was 11.5.ConclusionsRespiratory complications following abdominal wall reconstruction can be serious and are associated with prolonged hospitalizations. Patients with an increase in their plateau pressure of greater than 6 cmH(2)O are at an increased risk of severe postoperative respiratory complications.
