Background: Postoperative pulmonary complications are associated with significant morbidity and mortality in patients undergoing major surgeries. Acetylcysteine is a known antioxidant and is also used as a mucolytic agent to reduce hypersecretion and the viscosity of mucus secretions by the lung. Several studies have revealed that high doses of N-acetylcysteine can significantly prevent pulmonary complications. However, it has not yet been established whether low doses of N-acetylcysteine are also of clinical benefit. Here, we investigated the efficacy of a low dose of N-acetylcysteine, which was administered intravenously to patients under general anesthesia, in preventing perioperative deterioration of pulmonary function.
Methods: A total of 52 patients who were scheduled for nephrectomy were randomly assigned to receive either 600 mg of intravenous N-acetylcysteine or the same volume of normal saline. Patient hemodynamic and pulmonary parameters and the incidence of pulmonary complications were recorded and compared between the groups.
Results: No significant pulmonary complications occurred in either group. Moreover, no significant differences were observed regarding either patient characteristics or hemodynamic parameters between the two groups. Contrary to our expectations, the pulmonary parameters were also not significantly different between the two groups.
Conclusion: A low dose of N-acetylcysteine appears to have only limited value in preventing perioperative pulmonary complications.
