Arterial oxygenation during one-lung ventilation: combined versus general anesthesia.
UNLABELLED The optimal anesthetic management of patients undergoing thoracotomy for pulmonary resection has not been definitely determined. We evaluated whether general i.v. anesthesia (propofol-fentanyl) provides superior PaO2 during one-lung ventilation (OLV) compared with thoracic epidural anesthesia (TEA) with supplemental local and general anesthetics. We studied 60 patients who had prolon...
متن کاملHuman Oxygenation by Air during Anaesthesia: the Relation of Ventilatory Volume and Arterial Oxygen Saturation.
Ventilation and arterial oxygen saturation have been measured in 18 patients during anaesthesia with ether or halothane carried in air. All patients were ventilated artificially with a Jefferson ventilator at a frequency of 16 breaths per minute and variable tidal volume. Ventilation has been expressed as a percentage of Radford's standard, Nunn's standard and the patient's pre-operative restin...
متن کاملTidal hyperinflation during low tidal volume ventilation in acute respiratory distress syndrome.
RATIONALE Tidal volume and plateau pressure limitation decreases mortality in acute respiratory distress syndrome. Computed tomography demonstrated a small, normally aerated compartment on the top of poorly aerated and nonaerated compartments that may be hyperinflated by tidal inflation. OBJECTIVES We hypothesized that despite tidal volume and plateau pressure limitation, patients with a larg...
متن کاملVariation in the arterial to end-tidal PCO2 difference during one-lung thoracic anaesthesia.
We have measured the arterial to end-tidal PCO2 difference (PaCO2-PE'CO2) in 22 patients undergoing pulmonary resection in the lateral thoracotomy position during two-lung ventilation (TLV) and after transition to one-lung ventilation (OLV). With OLV for each patient, the practice of correcting the estimate by an initial measurement of (PaCO2-PE'CO2) was evaluated by subtracting the initial (Pa...
متن کاملEffect of Lung Manual Hyperinflation (MHI) on Oxygenation of Patients Following Abdominal Surgery and T-Tube Support
Background: Postoperative pulmonary complications (PPC) are of the major reasons for death. Prolonged mechanical ventilation (PMV) and delayed extubation are leading to the incidence of more seriously complications. The effect of hyperinflation has not been investigated in control of these complications in patients who have been weaned from mechanical ventilation and are undergoing T-tube suppo...
