Abstract

Objective: This study aims to know whether there are significant differences of blood sodium, potassium and hemoglobin level among patients post TURP who was irrigated by using normal saline and the sterile water. Material & Method: This is a single blind randomized clinical trial study performed from September 1, 2008 until August 31, 2009. Thirty-one subjects participated in this study. The subjects were divided into two groups, 14 subjects for normal saline (group I) irrigation and 17 subjects for sterilized water irrigation (group II). Results: There are statistically differences (p < 0,05) between hemoglobin concentrations changes in group I, and hemoglobin and sodium concentration changes in group II. There were no statistically differences (p > 0,05) in sodium and potassium changes in group I and potassium in group II. There are no statistically differences in hemoglobin, sodium, and potassium changes among two groups. Conclusion: Normal saline irrigant for irrigation after TURP give more stable post operative electrolyte profile compared to sterilized water. Keywords: TUR prostate, irrigation, serum sodium, potassium level differences.

Abstract

Stress analysis of the bender components in the design of the begel fabricator machine was carried out using FEA (Finite Element Analysis) with three variations of the constituent material parameters, namely 6061 aluminum, mild steel, and cast iron with a modulus of elasticity of 68.9 GPa, 220 GPa, 120.5 GPa, respectively. The test is carried out by a loading parameter 2520 MPa and fixed constraint. The maximum von misses stress and displacement obtained for each material parameter components using aluminum, mild steel, and cast iron are 17.78 MPa; 0.00765, 17.49 MPa; 0.00229, 17.62 MPa; 0.00427 respectively.
