Abstract :
Introduction: The increasing trend and need of bariatric surgeries has made it vital for the
anaesthesiologists to spruce up their knowledge regarding peri- operative management of morbidly obese
patients. Intra-operative fluid management in such patients is critical and has always been debatable.
Materials and Methods: We retrospectively assessed the influence of amount of fluid given intra-operative
ly and effect of hemodynamics on the renal function tests and acid-base status of 103 morbidly obese
patients undergoing laparoscopic bariatric surgery between April 2017 to March 2018 in our institution.
All the patients received central venous pressure guided fluids and were divided into two groups on the
basis of amount of fluid thereby administered as less than 2 litres and 2 litres or more.
Results: In our study, slight metabolic acidosis was seen patients receiving less than 2 Litres of fluid while
better hemodynamics were observed in patients receiving 2 litres of fluid or more intra -operatively.
Conclusion: Obese patients coming for laparoscopic bariatric surgery should receive intra-operative fluids
targeting optimal hemodynamics. Central venous pressure may not be an accurate predictor of fluid
responsiveness.
