Abstract
Background: One Lung Ventilation (OLV) remains standard procedure for thoracic surgery.
However, this procedure increases the risk of hypoxemia and desaturation that can influence
patients’ mortality and morbidity. The aim of this study was to evaluate the occurrence of
desaturation SpO2.
<93% in patients going pulmonal resections and to analyze the patients’ profiles.
Material and Method: In a retro-prospective study were included all data of patients who
underwent OLV for segmentectomy, lobectomy and bilobectomy, ASA I-III, with EF>50%,
FEV1
>40%, PaO2
>60mmHg and who went standardized anesthesia protocol. Patients with
prior radio or chemotherapy, with renal, hepatic, endocrine and coagulations disturbances
were excluded. In all patients we evaluated demographics, clinical data, surgery data and the
occurrence of desaturation (SpO2
<93%), 10 minutes, 30 and 40 minutes after OLV.
Results: Desaturation occurred in 20% of the patients 10 minutes after the OLV, in 32.5%
of the patients in the 30th and in 25% of the patients after the 40th minute. Significant number
of patients underwent right sight lobectomy. In none of the patients OLV was stopped and no
lethal outcome was registered.
Conclusion: In our study desaturation occurred from 20-32.5% of the patients who
underwent OLV during the first 40 minutes in respect to the time. Desaturation mainly occurred
in patients with right thoracotomy.
