Abstract:
Objective To analyze the risk factors of postoperatively prolonged mechanical ventilation (PMV) after liver transplantation.Method The clinical data of 117 patients who received liver transplantation were retrospectively reviewed.According to the duration of postoperative mechanical ventilation (＜24 h or ≥24 h),the patients were divided into two groups.Commonly-used clinical and lab indexes before,during and after operations were analyzed by using single variance logistic regression analysis,and the screened indexes were analyzed by stepwise multiple variance logistic regression analysis.Result Forty-two patients (35.9％) were diagnosed with PMV after liver transplantation.The intensive care unit stay in the control group was (1.60 ± 1.17) days,shorter than in PMV proup (9.35 ± 10.61days).Sixty indexes were analyzed by univarite logistic regression,and 49 indexes showed statistically significant differences (P ＜ 0.2).Multiple variance logistic regression analysis revealed that the levels of preoperative blood glucose,model for end-stage liver disease score (MELD),the blood loss volume during the operation and the levels of glutamic oxalacetic transaminase within 24 h after the operation showed significant difference.Conclusion Preoperative hyperglycemia,high MELD score,excessive intraoperative blood loss volume and the high level of glutamic oxalacetic transaminase after the operation are independent risk factors of PMV.
