Abstract
Background: Recent studies report the immunomodulatory lung-protective role of halogenated anaesthetics during lung resection surgery (LRS) but have not investigated differences in clinical postoperative pulmonary complications (PPCs). The main goal of the present study was to compare the effect of sevoflurane and propofol on the incidence of PPCs in patients undergoing LRS. The second aim was to compare pulmonary and systemic inflammatory responses to LRS.
Methods: Of 180 patients undergoing LRS recruited, data from 174 patients were analysed. Patients were randomized to two groups (propofol or sevoflurane) and were managed otherwise using the same anaesthetic protocol. Bronchoalveolar lavage (BAL) was performed in both lungs before and after one-lung ventilation for analysis of cytokines. Arterial blood was drawn for measurement of the cytokines analysed in the BAL fluid at five time points. Intraoperative haemodynamic and respiratory parameters, PPCs (defined following the ARISCAT study), and mortality during the first month and yr were recorded.
Results: More PPCs were detected in the propofol group (28.4% vs 14%, OR 2.44 [95% CI, 1.14-5.26]). First-yr mortality was significantly higher in the propofol group (12.5% vs 2.3%, OR 5.37 [95% CI, 1.23-23.54]). Expression of lung and systemic pro-inflammatory cytokines was greater in the propofol group than in the sevoflurane group. Pulmonary and systemic IL-10 release was less in the propofol group.
Conclusions: Our results suggest that administration of sevoflurane during LRS reduces the frequency of the PPCs recorded in our study and attenuates the pulmonary and systemic inflammatory response.
