Abstract:
Objective To investigate the risk factors for intraoperative hypotension (IOH) in patients undergoing double plasma molecular adsorption system (DPMAS) artificial liver support therapy. Methods Clinical data were collected from 181 patients (670 cases in total) who underwent DPMAS artificial liver support therapy in Liver Disease Center of The First Affiliated Hospital of University of Science and Technology of China from October 1, 2017 to December 31, 2020, and according to the presence or absence of IOH during DPMAS therapy, they were divided into IOH group with 70 patients and non-IOH group with 111 patients.Clinical indicators were compared between the two groups and their association with IOH was analyzed; prognosis was analyzed at 12 and 24 weeks.The independent samples t -test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test was used for comparison of categorical data between groups.Univariate and multivariate Logistic regression analyses were used to investigate the risk factors for IOH.The Kaplan-Meier method was used to plot receiver operating characteristic (ROC) curves, and the Z test was used for comparison of the area under the ROC curve (AUC) of independent risk factors. Results The univariate Logistic regression analysis showed that female individuals, individuals aged ≥50 years, and individuals with normal or low body mass index (BMI) tended to have a higher risk of IOH (all P < 0.05), and the multivariate analysis showed that normal or low BMI (odds ratio [ OR ]=3.290, 95% confidence interval [ CI ]: 1.523-7.108, P =0.002) and female sex ( OR =5.146, 95% CI : 2.316-11.432, P < 0.001) were independent risk factor for IOH in patients undergoing DPMAS artificial liver support therapy.The ROC curve analysis of female sex+BMI ≤24 kg/m 2 showed that it had an AUC of 0.639 in predicting IOH ( P =0.002).The patients experiencing IOH had a 12-week survival rate of 55.77%(29/52) and a 24-week survival rate of 50%(26/52), and there were significant differences between the two groups in 12-and 24-week survival rates (12-week: 76.53% vs 55.77%, χ 2 =6.887, P =0.009;24-week: 74.49% vs 50.00%, χ 2 =9.080, P =0.003). Conclusion The risk of hypotension was higher in female patients and that with normal or low BMI during DPMAS artificial liver therapy.Patients with IOH had poor survival prognosis at 24 weeks after DPMAS therapy.
