Effects of Different Oxygen Concentrations on Pulmonary Complications in Patients Undergoing Radical Resection of Esophageal Cancer (DOICA-E)
February 7, 2024 updated by: Wenfei Tan, China Medical University, China
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.

Detailed Description
Therefore, we should explore the most appropriate lung protection ventilation strategy to reduce the occurrence of pulmonary complications.
The recommended standard of international expert group on lung protective ventilation strategy points out that the lowest concentration of oxygen (≤40%) should be inhaled as much as possible during mechanical ventilation to maintain normal blood oxygen level (SpO2≥94%).
If the mixed gas with low inhaled oxygen concentration can achieve ideal oxygen saturation and arterial oxygen partial pressure, it may reduce the postoperative pulmonary complications of the subjects.
However, there are few reports on the influence of different oxygen concentrations on pulmonary complications in patients undergoing radical resection of esophageal cancer.
This study intends to explore the influence of different oxygen concentrations on pulmonary complications in patients undergoing radical resection of esophageal cancer.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
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%.

Placebo Comparator: Experimental: 60% Oxygen
Before anesthesia induction, the participants inhaled pure oxygen through the mask for 5 minutes.
After successful anesthesia induction, FiO2 will be adjusted to 100% in one lung ventilation and 60% 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.
