ARTICLE HIGHLIGHTS
Research background

Mechanical ventilation can lead to the severe impairment of the metabolic pathway of alveolar surfactants, inactivating alveolar surfactants and significantly reducing lung-chest compliance. The cardiopulmonary function of elderly patients usually reduced to a certain extent, and there are lung complications after surgical anesthesia, just like lung barotrauma caused by mechanical ventilation, atelectasis and postoperative hypoxemia.

Research motivation

This study investigated the effects of different positive end expiratory pressures (PEEPs) and tidal volumes (VTs) on respiratory function, the degree of the inflammatory response and hemodynamic indexes in patients undergoing surgery under general anesthesia.

Research objectives

This research aimed to explore the effects of different PEEP and VT control on lung protection and inflammatory factors during surgical anesthesia

Research methods

A total of 120 patients undergoing surgery for gastric or colon cancer under general anesthesia in Xinghua People's Hospital from January 2017 to January 2021 were included.

Research results

There were no significant differences in PaCO2, PaO2, oxygen or the examined indexes at T0 between group A and group B. The measured PaO2 value of patients in group A at T3 was higher than that in group B, and the difference was significant. The measured peak airway pressure value of patients in group A at T1 was higher than that in group B, and the difference was significant. The measured dynamic pulmonary compliance value at T1 and T2 was greater than that in group B).

Research conclusions

For patients undergoing surgery for gastric or colon cancer under general anesthesia, the VT (6.0 mL/kg) + PEEP (5.0 cmH2O) regimen was more effective than the VT (6.0 mL/kg) + PEEP (8.0 cmH2O) regimen in protecting the lung function and ventilatory function of patients, and it had better effects on maintaining hemodynamic stability and reducing inflammatory reactions.

Research perspectives

For patients undergoing gastric or colon cancer surgery under general anesthesia, the VT (6.0 mL/kg) + PEEP (5.0 cmH2O) regimen is more valuable in clinical promotion than the VT (6.0 mL/kg) + PEEP (8.0 cmH2O) regimen.
