One-lung ventilation is well tolerated in dogs undergoing thoracoscopic surgery irrespective of device or side of lung blocked.

OLV is well-tolerated in dogs undergoing thoracoscopic surgery with excellent outcomes.

This multi-institutional retrospective study evaluated one-lung ventilation (OLV) outcomes in 93 dogs undergoing thoracoscopic surgery between 2013-2023. OLV was successfully achieved in 90 of 93 dogs using various devices: endobronchial blockers (n=71), double-lumen tubes (n=15), selective intubation (n=1), and unspecified (n=6). The median patient age was 9.5 years with a weight range of 2.5-62.8 kg. Intraoperative blood gas abnormalities were common, with grade 2 hypercapnia in 62 dogs and grade 3 hypercapnia in 11 dogs; grade 2 hypoxemia occurred in 10 dogs and grade 3 in 6 dogs. Notably, left bronchus blockade resulted in significantly lower odds of grade 2 hypoxemia compared to right-sided blockade. Although 23 cases required conversion to open thoracotomy, only 4 conversions were directly attributable to OLV complications. Blood gas abnormalities typically resolved postoperatively. The study demonstrates that OLV is a well-tolerated and effective technique for thoracoscopic procedures in dogs, with excellent short-term outcomes regardless of device type or lung side.
