Background: We evaluated the safety and feasibility of one-lung ventilation in obese patients undergoing thoracoscopic lobectomy and whether obesity affected peri- and postoperative outcomes.Methods: This was a retrospective single center study including consecutive patients undergoing thoracoscopic lobectomy between October 2019 and February 2022. Obese patients were statistically compared to a control group to evaluate any differences in relation to one-lung ventilation and peri- and postoperative outcomes.Results: Our study population included 111 patients; of these, 26 (23%) were included in the obese group, while 85 (77%) were included within the nonobese group. To obtain one-lung ventilation in nonobese patients, a double-lumen tube was more frequently used than a single-lumen tube with bronchial blocker (61% vs. 39%; p = 0.02), while in obese patients a single-lumen tube with bronchial blocker was used more than a double-lumen tube (81% vs. 19%, p = 0.001). Intergroup comparison showed that a double-lumen tube was the preferred method in nonobese patients, while a single-lumen tube with bronchial blockers was the strategy of choice in obese patients (p = 0.0002). Intubation time was longer in the obese group than in the nonobese group (94.0 +/- 6.1 vs. 85.0 +/- 7.0 s; p = 0.0004) and failure rate of first attempt at intubation was higher in the obese group (23% vs. 5%; p = 0.01). Obesity was not associated with increased intra-, peri- and postoperative complications and/or mortality.Conclusions: One-lung ventilation is a feasible and safe procedure also in obese patients and obesity did not negatively affect peri- and postoperative outcomes after lung resection.

Abstract

Background: We evaluated the safety and feasibility of one-lung ventilation in obese patients undergoing thoracoscopic lobectomy and whether obesity affected peri- and postoperative outcomes.Methods: This was a retrospective single center study including consecutive patients undergoing thoracoscopic lobectomy between October 2019 and February 2022. Obese patients were statistically compared to a control group to evaluate any differences in relation to one-lung ventilation and peri- and postoperative outcomes.Results: Our study population included 111 patients; of these, 26 (23%) were included in the obese group, while 85 (77%) were included within the nonobese group. To obtain one-lung ventilation in nonobese patients, a double-lumen tube was more frequently used than a single-lumen tube with bronchial blocker (61% vs. 39%; p = 0.02), while in obese patients a single-lumen tube with bronchial blocker was used more than a double-lumen tube (81% vs. 19%, p = 0.001). Intergroup comparison showed that a double-lumen tube was the preferred method in nonobese patients, while a single-lumen tube with bronchial blockers was the strategy of choice in obese patients (p = 0.0002). Intubation time was longer in the obese group than in the nonobese group (94.0 +/- 6.1 vs. 85.0 +/- 7.0 s; p = 0.0004) and failure rate of first attempt at intubation was higher in the obese group (23% vs. 5%; p = 0.01). Obesity was not associated with increased intra-, peri- and postoperative complications and/or mortality.Conclusions: One-lung ventilation is a feasible and safe procedure also in obese patients and obesity did not negatively affect peri- and postoperative outcomes after lung resection.
