A Study on the Application of Modified Positive Pressure Extubation Technique in General Anesthesia Recovery in the Post-Anesthesia Care Unit (PACU)

Objective: To investigate the application effect of the modified positive pressure extubation technique in general anesthesia recovery in the PACU. Methods: A total of 200 patients who underwent general anesthesia surgery and entered the PACU for recovery from January 2024 to April 2025 at a medical center were selected and randomly divided into the modified positive pressure extubation group (intervention group) and the traditional extubation group (control group), with 100 cases in each group. Physiological parameters before and after extubation and the incidence of hypoxemia were collected and compared between the two groups. Results: The modified positive pressure extubation group showed better fluctuation rates of three physiological parameters—systolic blood pressure, heart rate, and oxygen saturation—after extubation compared to the traditional negative pressure extubation group. The incidence of hypoxemia complications was significantly reduced in the modified positive pressure extubation group. Discussion: The modified positive pressure extubation technique buffers the pressure changes at the moment of extubation through positive pressure ventilation, reducing interference with the patient’s physiological functions, decreasing stress responses triggered by airway irritation, and maintaining respiratory and circulatory stability in patients. Compared with traditional negative pressure extubation techniques, this technique demonstrates significant advantages in stabilizing physiological parameters and reducing complications, especially during the general anesthesia recovery stage in the PACU. Although the current study still has certain limitations, it has a broad application prospect in the future and is expected to provide a safer and more effective option for extubation operations during general anesthesia recovery in the PACU. Conclusion: The modified positive pressure extubation technique has significant advantages in general anesthesia recovery in the PACU. It can effectively stabilize physiological parameters after extubation, reduce the incidence of complications, and enhance patient comfort and extubation safety, with high clinical promotion value.
