Predictive factors for hypoxemia during one-lung ventilation at Dr. Salvador Allende hospital. Rev cuba anestesiol reanim [online]. 2014, vol.13, n.3, pp.241-252. ISSN 1726-6718.

Introduction: maintaining adequate oxygenation during one-lung ventilation is the main concern in thoracic surgery. Prior identification of patients who may present arterial oxygenation alterations is an important advantage. Objectives: determine the incidence of hypoxemia during one-lung ventilation, as well as the pre- and intraoperative variables predicting it. Methods: an observational analytical retrospective cohort study was conducted at Dr. Salvador Allende hospital. The study population was all patients requiring intrathoracic surgery from January 2007 to December 2011. Results: incidence of hypoxemia during one-lung ventilation was 9.7%. Height under 160 cm and the side operated on (right) showed a statistically significant relationship to the possibility of developing hypoxemia during one-lung ventilation. Conclusions: hypoxemia during one-lung ventilation is a current problem at the study hospital. Although statistically significant variables are not very modifiable, at least they serve as indicators for patients at greater risk.

Keywords : hypoxemia; one-lung ventilation; predictive factors.
