RESUMEN
PURPOSE: Patients with end-stage renal disease (ESRD) have higher risks of subdural hemorrhage (SDH) and subsequent 30-day mortality. However, evidences regarding optimal mode of dialysis therapy during acute management are sparse. We aimed to compare the outcomes of ESRD patients who received continuous peritoneal dialysis (CPD) or extended hemodialysis (EHD) after SDH and determined factors associated with 30-day mortality. METHODS: We retrospectively reviewed consecutive patients with SDH and ESRD in a medical center. The clinical parameters and outcomes were compared between CPD and EHD groups. Factors associated with 30-day mortality were analyzed. RESULTS: We reviewed 32 patients, including 22 received EHD, 8 received CPD, and 2 received continuous veno-venous hemodialysis. Neurosurgery was done in 9 (28%) of them. There was no significant difference in baseline parameters and outcomes between EHD and CPD groups. The overall 30-day mortality rate was 19%. Lower Glasgow coma scale (GCS, median [interquartile range]: 10 [7-12] vs. 15 [11-15], p = 0.02) and larger changes in absolute mean arterial pressure (MAP: 26.5 [10.5-46.0] vs. 7.5 [2.0-17.8] mmHg, p = 0.01) during the first dialysis therapy were noted in patients with 30-day mortality. In multivariate analysis, consciousness disturbance at presentation was an independent risk factor for 30-day mortality. CONCLUSION: Among ESRD patients with SDH, the 30-day mortality rates were similar between EHD and CPD groups. MAP change during dialysis might be an important modifiable risk factor for 30-day mortality, though the effect was not significant in multivariate analysis. Further prospective studies with larger sample size are warranted.
