This procedure was then repeated through the use of four-digit matching, then three-digit matching, and so forth. The process proceeded sequentially to a single-digit match on propensity score. Distinctions concerning matched pairs have been selleck chem tested through the use of a paired t test, Wilcoxon test, and McNemar X2 statistics, as ideal.All statistics have been two-tailed. A P value of significantly less than 0.05 was viewed as to be substantial. Constant variables are presented as mean��standard deviation or median (25% to 75% interquartile array) and categorical variables as amount and percentage, except if otherwise indicated.ResultsCharacteristics from the research cohortDuring the examine period, twelve,938 patients had been admitted to our surgical ICU (indicate age=62.5?many years (conventional deviation 14.9), male=63.2%).
The qualities of the study groups on admission for the ICU are shown in Table?1. The prevalence of ESRD on admission for the ICU was 1.5% (n=199). Diabetic (forty.2%) and hypertensive (23.6%) nephropathies have been the most common leads to of ESRD, followed by inflammatory situations (persistent glomerulonephritis, interstitial nephritis, chronic pyelonephritis, and nephritic syndrome: sixteen.5%), congenital illnesses (renal hypoplasia and polycystic kidney: six.5%), and neoplasm (4.0%). Amongst sufferers with ESRD, 117 (58.8%) have been anuric, whereas 82 individuals (41.2%) had residual diuresis prior to ICU admission (�� or >500?mL/day in 40 and 42 patients, respectively). The predominant mode of dialysis in patients with ESRD was hemodialysis (98.0%); in 64.3% of instances, this was carried out by an arterio-venous shunt and in 34% as a result of a appropriate atrial catheter.
Only four sufferers (2%) were treated by peritoneal dialysis.Table 1Characteristics from the study group on admission for the intensive care unit according on the presence of end-stage renal diseasePatients with ESRD had been much more likely to be male (72.9% vs. 63.0%, P = 0.004), had greater severity scores, and had a greater incidence of diabetes mellitus and cirrhosis and lower incidence of cancer on admission towards the ICU than individuals with out ESRD (Table?1). Gastrointestinal surgical treatment was additional typical (29.6% vs. 21.4%, P <0.001) and neurosurgical procedures less common (15.9% vs. 4.0%, P <0.001) in patients with ESRD compared with those without ESRD.
Serum urea, serum creatinine, leukocyte count, and serum potassium have been increased whereas hematocrit values, platelet counts, pH, serum bicarbonate, and serum sodium levels have been lower in sufferers with ESRD than people without having ESRD (Extra file 1: Table S2).Morbidity and mortalityThe most prevalent organ failures on admission to the ICU and at any time throughout the ICU remain have been cardiovascular (46.2% and 49.5%) followed by central nervous method (36.7% and 42.4%) and respiratory (24.1% and thirty.9%) failures. Sufferers with ESRD have been extra likely to have any kind of organ failure on admission on the ICU and at any time through the ICU keep than those without ESRD (Table?two).
