Effects of Different Oxygen Concentrations on Pulmonary Complications in Patients Undergoing Radical Resection of Esophageal Cancer
Status: Recruiting
Location: See location...
Intervention Type: Drug
Study Type: Interventional
Study Phase: Phase 4
SUMMARY
Radical operation of esophageal cancer is complicated and traumatic, and ventilation with one lung in lateral position and ventilation with both lungs after supine position requires long-term tracheal intubation and ventilator-assisted ventilation, and the incidence of postoperative pulmonary complications is high.

Time Frame

Estimated Completion Date: 2026-09-30
Participants
Target number of participants: 100
Treatments
Experimental: Experimental: 30% Oxygen
Before anesthesia induction, the participants inhaled pure oxygen through the mask for 5 minuets. After successful anesthesia induction, FiO2 will be adjusted to 60% in one lung ventilation and 30% FIO2 in both lungs ventilation, and the total gas flow rate will be set at 2L/min. All patients will be performed via the lung protective ventilation strategy. The respiratory parameters are VT: 6-8ml/kg, PEEP: 6-8 cm H2O, RR: 1:2. Manual lung recruitment maneuvers will be performed after tracheal intubation and before tracheal extubation, however when intraoperative oxygen saturation is less than 92% the manual lung recruitment maneuver will be done too. Arterial blood will be collected for blood gas analysis. Patients in both groups will be extubation the operating room and then sent to the PACU. patients should transfer to 60% Oxygen group if intraoperative oxygen saturation less than 85%.
