Aim: To study the patterns of presentation in patients of Acute Kidney Injury requiring Short Term Hemodialysis, duration of Hemodialysis required in different presentations, problems and complications of vascular access,complications during Short Term Hemodialysis, outcome of patients with Acute Kidney Injury undergoing Hemodialysis with respect to their presentation.
Materials & Methods: The study was undertaken at our college under the department of Medicine. It was an observational study carried out for 64 patients, suffering from Acute Kidney Injury requiring Short Term Hemodialysis, with presentations of wide variety of medical and surgical disorders necessitating admission in intensive care unit. Duration of study was 2 years, from January 2010 to December 2011.
Results:Study showed a male preponderance (75%). Higher mortality was observed in the age groups of 61 to 90. There was a significant association between increased pre dialysis Blood Urea Level and mortality (p= 0.001) while no significant association between pre dialysis serum creatinine and mortality was found (p= 0.861). Acute gastroenteritis(n= 14, 21.9%) was the most common presentation of AKI requiring hemodialysis. Patients of acute gastroenteritis, acute pyelonephritis and malaria had complete recovery. Commonest complication of hemodialysis was hypotension in 33 patients (51.6%), followed by vomiting(28.1%) and fever with rigors (26.6%). Femoral vein (n=45, 70.3%) was most common vascular access used in our study followed by internal jugular vein (n=11, 17.2%) and subclavianvein (n=8, 12.5%).
Conclusion: Early initiation of Short Term Hemodialysis in hemodynamically stable Acute Kidney Injury patients, whose underlying cause is treatable, is likely to result in complete recovery.
