Oxygenation during one-lung ventilation with propofol or sevoflurane.
2009
: 60 patients, ASA I-III, underwent one-lung ventilation for open or video-assisted thoracic surgery randomized either with intravenous anesthesia with propofol or with inhalational anesthesia with 1 MAC sevoflurane. Propofol was titrated during one-lung ventilation to achieve a mean arterial pressure of 75-80 mmHg. Blood gas analyses, hemodynamic and respiratory parameters were measured during two-lung ventilation at the beginning of the surgical procedure and 10 min, 20 min and 30 min after start of one-lung ventilation. At all time points, hemodynamic and respiratory parameters were comparable in both groups. Oxygenation did not differ between groups at comparable mean arterial blood pressures.
