Abstract:
Objective:To analyze the effect of anticoagulant or antiplatelet drugs on bleeding and cardio-cerebral vascular events in perioperative period of catherization for peritoneal dialysis.Methods:The clinical data of patients undergoing peritoneal dialysis catheterization in Peking University Third Hospital from July 1, 2010 to December 31, 2020 were collected and analyzed retrospectively. The patients were divided into drugs discontinuation group and drugs continuation group according to whether the anticoagulant drugs or antiplatelet drugs were discontinued or not. Baseline clinical data and bleeding and cardio-cerebral events after surgery were compared between the two groups. Multivariate logistic regression model was used to analyze the influencing factors for bleeding and cardio-cerebral events.Results:A total of 57 patients were included in the study, with 34 males and 23 females. The age was (67.37±13.93) years old (range from 27 to 97 years old). There were 37 patients in drugs discontinuation group and 20 patients in drugs continuation group. The proportions of acute myocardial infarction events in drugs continuation group were higher than those in drugs discontinuation group in 3 months and 6 months before surgery (10/20 vs 3/37, χ2=10.671, P=0.001; 11/20 vs 3/37, χ2=12.980, P<0.001 respectively). The median drugs discontinuation time was 5.0(2.0, 14.0) d (range from 1 to 30 d) before surgery, and median restore medication time was 4.0(3.0, 7.0) d (range from 1 to 14 d) after surgery in drugs discontinuation group. There was no significant difference in the proportion of bleeding (10/37 vs 8/20, χ2=1.011, P=0.315) and cardio-cerebral events (4/37 vs 0/20, χ2=0.964, P=0.326) between drugs discontinuation group and drugs continuation group within 2 weeks after surgery. The results of multivariate logistic regression analysis showed that drugs discontinuation before surgery was not an independent influencing factor for bleeding events ( OR=0.656, 95% CI 0.195-2.206, P=0.496), however combination of aspirin and clopidogrel before surgery was an independent influencing factor for bleeding events ( OR=4.038, 95% CI 1.044-15.626, P=0.043). All cardio-cerebral events (4 cases) happened in drugs discontinuation group, and myocardial angina in 6 months before surgery ( OR=9.764, 95% CI 0.928-102.682, P=0.058) and increased serum calcium concentration ( OR=1.491, 95% CI 0.976-2.278, P=0.065) were related with an elevated trend for cardio-cerebral events. Conclusions:Whether anticoagulant or antiplatelet drugs are discontinued before catherization surgery for peritoneal dialysis is not an independent influencing factor for bleeding events after surgery. The risk of postoperative bleeding in patients using combination of aspirin and clopidogrel should be paid attention. Myocardial angina in 6 months before surgery and higher serum calcium are related with an elevated trend for cardio-cerebral events after drugs discontinuation.
