SERUM SODIUM AND SERUM POTASSIUM CHANGES DURING TRANSURETHRAL RESECTION OF PROSTATE GLAND IN PATIENTS UNDER SUBARACHNOID BLOCK

Abstract

Objective: This prospective study was design to study the changes occurring in serum level of Na & k during TURP in Spinal anaesthesia & also other factor like amount of irrigating fluid absorbed, resection time, height of irrigation, amount of gland resected & concurrent hemodynamic changes occurring during procedure.

Method: This study was conducted in 50 male patients at JJ hospital, MUMBAI undergoing TURP under spinal anaesthesia. The changes in serum Na & K were studied by taking blood samples in preoperative period (in preop room), intraoperative period(20 min after start of resection),post operative period( 30 min after end of surgery).Then patient were divided into two groups ,group 1 resection time ≤ 30 min & group 2 resection time > 30 min.

Result: The serum Na⁺ did not changed significantly in either of the groups. The serum K⁺ did changed significantly. There was significant rise in serum K⁺ level in post operative period in group II as compared to preoperative level. The changes in serum K⁺ were related to duration of resection.

Conclusion: Perioperative monitoring of the serum electrolytes Na & k is important for safety of patient.
