title: Outcomes and characteristics of intermittent hemodialysis for acute kidney injury in an intensive care unit.
abstract: Renal replacement therapy in intensive care units (ICUs) varies globally and is dependent on medical and non-medical factors. We performed a retrospective analysis of patients initiated on dialysis in an ICU. Patient and clinical characteristics, cause of kidney injury, laboratory parameters, hemodialysis characteristics, and survival were reviewed. Acute physiological and chronic health (APACHE II) score was use to study the sickness profile. A total of 92 patients underwent 525 hemodialysis sessions. There were 60 male and 32 female patients. The mean age of the patients was 56.5 ± 16 years. The cause of acute kidney injury included sepsis 64, cardiac 7, malaria 7, postoperative 4, trauma 3, poisoning 2, and others 4. Vasopressors were used in 75% and mechanical ventilation was used in 74 (82%) of the cases. APACHE II score was 22.3 + 7.4. The mean creatinine level was 3.6 + 3.7 mg/dl. The duration of dialysis was less than 4 h in 324 (61.2%) sessions and greater than 6 h in 118 (22.5%) sessions. The percentage of 30-day survival was 30%. Intermittent hemodialysis customized to renal support needs of ICU patients is an appropriate option in resource-limited settings.
