توزیع فراوانی نارسایی حاد کلیوی در بیماران بستری در بخش مراقبتهای ویژه مرکز پزشکی الزهرا (س) اصفهان

Acute renal failure ( ARF ) can increase mortality and morbidity , hospital stay and costs . So ,carefull information about frequency distribution , mortality and morbidity , male : female ratio and other characteristics of ARF in ICU have important role to prevent and manage patients and to predict equipments and trainees personel . Therefor this evaluation considered to be necessary for above evidence Materials and Methods: In this analytic - descriptive study , 1383 patients were investigated in surgery ICU during 1996 - 2000. Findings were collected based on age , sex , admission cause , etiology , mortality and morbidity . Datas were analyzed statistically Results: Frequency of ARF was 25.9 percent . The most common cause of ARF was prerenal factors (57.9 percent) that include : surgery drainage , bleeding and trauma . The most frequence of age group was > 70 y (25.6 percent) and the least was 31 - 40 years old . Total mean age of patients were 36.5 19 y and about ARF were 52 5.8 y (P < 0.05). Males (30.3 percent) were more than females (19.9 percent) (P < 0.05) . Mortality rate in ARF was 57.9 percent and in other patients was 12.8 percent (P < 0.05) Conclusion: Relative frequency percentage of ARF indidcates its high frequency among hospitalized patients in ICU . Incidence of ARF increase with age and is similar to previous studies . It is probably due to underlying diseases and reduction of renal function in this age group . Males were more than female because of increasing trauma and surgery in this group . The most common cause of prerenal ARF was large amount of blood and fluids loss . Mortality rate was more than previous studies and was statistically significant . It is probably evidences of injury severity and co-existing disturbances . Because of high incidence of ARF in ICU it is necessary to maintain patients hemdynamic status , infuse enough fluids , adjust drug doses , &hellip; for immediate diagnosis and treatment of these patients.
