ABSTRACT
Background: Chang in the serum K+ level may increase perioperative morbidity and mortality in kidney transplant recipients. Thus this research was done with the aim of evaluated of K+ change in kidney transplant recipients. Hence the following study was carried to evaluate the fluctuation of potassium ion in the kidney transplant recipient patients. Materials and Methods: In a simple randomized clinical trial the serum K+ level was assessed in 40 kidney transplant candidates as following interval, pretransplantation, during renal art, anastomosis, after diuresis and post transplantation period. After hydration with 5 ml/kg normal saline all patient were undergone general anesthesia identically. They were premedicated fentanyl (2µg/kg), induction was performed by thiopental sodium (5 mg/kg). Tracheal intubation was facifitated with atracurium (0.6 mg/kg). Anesthesia was maintained with N2O + O2 50%, halothane 0.1% and fentonyl 1 µg/kg every 30 min. Results: The least mean K+ level was during anastomosis (ie. 3.5±0.24 mmol/L) and showed a decrease in the serum K+ level compared to preoperative period (mean 4.4±0.48 mmol) (P< 0.001). The maximum serum K+ level detected preoperatively and postoperatively were 5 (mmol/ L) and 4.7 (mmol/L) respectively. Conclusion: Despite the above results we inferred that range of serum K+ level was maintained within normal. Therefore with suitable pereoprative assessment hyperkalemia is a rare occurrence in transplant recipients.
