Abstract
Aim. This study aimed at examining the effect of preoperative fluid therapy on kidney function in patients undergoing heart surgery.
Background. As one of surgery complications, kidney failure occurs with oliguria and rise in creatinine. Decreased heart output leads to reduction in renal perfusion. Acute renal failure is associated with increase in morbidity, mortality and high medical treatment cost. Various studies has indicated an increase in postoperative mortality rate when complications of acute renal failure superimpose the situation. One of the best strategies for kidney protection is optimizing preoperative hemodynamics and fluid therapy.
Method. In this clinical trial study, 107 patients were recruited based on inclusion criteria and randomly allocated to experimental (n=54) and control (n=53) group. Patients in experimental group received Half- Saline, 1cc/kg/hr, during 12 hours before surgery. Patients in control group started as being NPO, 8 hours before the surgery. Creatinine level, BUN, and 24-hours urine output were measured and recorded during two days after surgery. Data were analyzed in SPSS V.22 using descriptive and inferential statistics.
Findings. The groups didnchr('39')t differ in terms of age, gender, weight, and ejection fraction. There was no statistically significant difference between experimental and control group in terms of creatinine changes during the preoperative day and the first and the second day after surgery. Also, there was no statistically significant difference between groups in BUN on the first and second days after surgery. The urine output of the experimental group was greater than control group on first and second days after operation, but the difference was not significant. The duration of ICU stay were similar in both groups. There were recorded two deaths in control group while there was no death in experimental group.
Conclusion. It was concluded that preoperative fluid therapy has no short-term effect on kidney function. It is recommended to examine the effect of fluid therapy on kidney function in longer periods.
