Prolonged pneumoperitomeum in LRC leads to impairement in haemodynamics and organ perfusion. Optimizing cardiac preload by fluid replacement is required. Methods: 80 patients (ASA ІІ, ІІІ) were divided into 2 equal groups. Group І: received 2ml/kg/hr LR, group ІІ received 8ml/kg/hrLR, both groups receive 8m/kg as preload. Results: No statistical significant difference was found in HR and MAP while there was statistical significant difference in CVP, AST, urea, creatinine and urine output. Conclusion: 8ml/kg/hr maintained haemodynamic stability and organ perfusion.
