    AbstractConventional open heart surgery with cardiopulmonary bypass (CPB) are associated with transient post-operative renal dysfunction which is caused by systemic inflammatory response induced by CPB. Corticosteroids are administered to attenuate the systemic inflammatory response. The purpose of this study was to compare the effects of pre-bypass and post-bypass methylprednisolone on postoperative renal function after correction of ASD under CPB. Forty (40) patients were selected in the University cardiac centre of BSMMU undergoing ASD correction under CPB. Patients were randomized into two group to receive pre-bypass (Group A) or post-bypass (Group B) methylprednisolone 30mg/kg. Markers of glomerular function (BUN, serum creatinine, creatinine clearance) and damage (micro-albuminuria) and tubular function (glucosuria) were evaluated 24 hours after operation. Transient impairment of glomerular and tubular function of kidney was observed in patients those received post-bypass metylprednisolone (Group B) while Group A patients shown no significant difference between baseline and post-operative renal function. Use of pre-bypass methylprednisolone has a protective effect on post-operative renal function after correction of ASD under CPB.
