Increased mortality and morbidity are reported in association with high ultrafiltration rate (UFR) and with long dialysis recovery time (DRT). We studied the association between UFR and DRT.
This is a cross-sectional, observational study was conducted. Patients on thrice-weekly hemodialysis (HD) with self-reported DRT between August and December 2014 were included. We examined the association of 30-day average UFR with recovery time.
The total number of patients included in this study was 2,689. DRT in categories of immediate recovery, >0-≤2, >2-≤6, >6-≤12, and >12 h, were reported in 27, 28, 17, 9, and 20% of the patients respectively. In multivariable analysis, longer DRT was associated with female gender, non-black race, higher body weight, lower serum albumin, chronic heart failure, cerebrovascular disease, missed dialysis sessions, higher pre-dialysis systolic blood pressure, and larger UF volume. Compared to UFR of <10, UFR ≥13 mL/kg/h was associated with longer DRT, OR of 1.16 (95% CI 0.99-1.36), and 1.28 (95% CI 1.06-1.54) in the unadjusted and the adjusted analyses respectively. Intradialytic hypotension was also associated with longer DRT in the unadjusted (per 10% higher frequency, OR 1.04 [95% CI 1.01-1.07]) and adjusted analyses (OR 1.03 [95% CI 1.00-1.07]).
Long recovery time is common after HD. Rapid fluid removal is associated with longer DRT.
据报道，高超滤率（UFR）和长透析恢复时间（DRT）与死亡率和发病率增加相关。我们研究了UFR与DRT之间的关联。
进行了一项横断面观察性研究。纳入2014年8月至12月期间每周进行三次血液透析（HD）且自我报告有DRT的患者。我们检查了30天平均UFR与恢复时间的关联。
本研究纳入的患者总数为2689例。分别有27%、28%、17%、9%和20%的患者报告即时恢复、>0至≤2小时、>2至≤6小时、>6至≤12小时和>12小时的DRT。在多变量分析中，较长的DRT与女性、非黑人种族、较高体重、较低血清白蛋白、慢性心力衰竭、脑血管疾病、错过透析次数、透析前较高收缩压和较大超滤量相关。与UFR<10相比，UFR≥13 mL/kg/h在未调整和调整分析中分别与较长的DRT相关，比值比分别为1.16（95%可信区间0.99 - 1.36）和1.28（95%可信区间1.06 - 1.54）。透析中低血压在未调整（每增加10%频率，比值比1.04 [95%可信区间1.01 - 1.07]）和调整分析（比值比1.03 [95%可信区间1.00 - 1.07]）中也与较长的DRT相关。
HD后恢复时间长很常见。快速液体清除与较长的DRT相关。
