To be included in the study, patients were required to undergo an elective thoracic procedure requiring lateral positioning and one-lung ventilation
. Patients were excluded if they had an ASA physical status greater than II, were aged greater than 80 or less than 18 years; had a body mass index greater than 35 kg x [m.sup.-2]; were identified as having a risk of aspiration or difficult tracheal intubation, or if they had any of the following conditions: symptomatic ischaemic heart disease, pregnancy, liver disease, allergy to propofol, opioid tolerance or previous anaesthetic awareness.

Effects of ventilatory mode during one-lung ventilation
on intraoperative and postoperative arterial oxygenation in thoracic surgery.
(OLV) is a common ventilation technique during thoracic surgery that can achieve double-lung isolation effectively, provide a good view and operating space for the surgeon, and protect normal lungs from hemorrhage or abscess caused by the affected lung.[sup] However, OLV can cause an imbalance of the ventilation/perfusion (V/Q) ratio and increase intrapulmonary shunt.
Although LPV is widely used in clinical settings, particularly in one-lung ventilation
and abdominal surgery, there have been no studies on LPV in patients without lung pathology undergoing craniocerebral surgery.
OLV is employed to provide one-lung ventilation
in patients undergoing thoracic, cardiac, vascular, or esophageal surgeries.
VATS is one such procedure used in visualization of intrathoracic structures which requires a partially or totally collapsed ipsilateral lung and hence needs one-lung ventilation
Recent papers suggest protective ventilation (PV) as a primary ventilation strategy during one-lung ventilation
(OLV) to reduce postoperative pulmonary morbidity.
