Abstract:

Objective

To identify independent risk factors for postoperative pulmonary complications (PPCs) in patients receiving massive transfusion during retroperitoneal tumor resection and to analyze the impact of PPCs on short-term patient outcomes.

Methods

A retrospective analysis was conducted on 114 patients who underwent elective retroperitoneal tumor resection and received massive transfusion at Peking University International Hospital between January 2014 and December 2023. Data including baseline characteristics, intraoperative transfusion and fluid infusion, intraoperative body temperature, laboratory test results, and postoperative outcomes were collected. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for PPCs. The severity of postoperative complications, duration of mechanical ventilation, length of ICU stay, postoperative hospital stay, total hospital stay, rate of unplanned ICU admission, 24-hour mortality, and 30-day mortality were compared between patients with and without PPCs.

Results

The incidence of PPCs was 57.0% (65/114). Multivariate logistic regression analysis identified hyperglycemia at the end of surgery as an independent risk factor for PPCs. Compared to the non-PPCs group, the PPCs group had significantly prolonged duration of mechanical ventilation and ICU stay. There was also a trend towards increased 30-day mortality in the PPCs group.

Conclusion

Elevated blood glucose at the end of surgery is independently associated with the occurrence of PPCs in patients undergoing retroperitoneal tumor resection with massive transfusion. PPCs significantly prolong the duration of mechanical ventilation and ICU stay and may increase mortality risk. Therefore, it is essential to strengthen perioperative blood glucose monitoring and management in these patients.
