Randomized Trial of Restrictive Versus Liberal Perioperative Fluid Management for Patients Undergoing Pancreatic Resection

アクティブコンパレータ：pts undergoing pancreatic resection Restrictive arm

All patients will receive Normosol or equivalent solution, 0.5 ml/kg/fasted hour IV (approximately from 8am to time of induction) during induction of anesthesia. All patients will then receive maintenance fluids consisting of Normosol or equivalent solution at 6 ml/kg/operative hour. After randomization occurs, those patients randomized to the Restricted Arm will continue to receive Normosol or equivalent solution at 6ml/kg/operative hour.

Normosol or equivalent solution 0.5 ml/kg/fasted hour IV (8am to time of induction) during induction of Anesthesia. Maintenance IV Normosol or equivalent solution at 6 ml/kg/operative hour. Blood loss to be replaced volume: volume with colloid until transfusion criteria met. Additional fluid boluses of 100ml Normosol or equivalent solution or bolus pressors (phenylephrine 40mcg or ephedrine 5mg) at the discretion of the Anesthesiologist to maintain patient hemodynamic stability.

All patients will receive Normosol or equivalent solution, 0.5 ml/kg/fasted hour IV (approximately from midnight to time of induction) during induction of anesthesia. All patients will then receive maintenance fluids consisting of Normosol or equivalent solution at 6 ml/kg/operative hour. Those patients randomized to the Liberal Arm will receive an additional Normosol bolus or equivalent solution equal to (another) 1.5 ml/kg/fasted hour IV (to bring the total to 2 ml/kg/fasted hour) plus an additional bolus of Normosol or equivalent solution 6ml/kg/operative hour to bring the hourly rate to 12ml/kg/operative hour with a maximum of 1000 ml/operative hour.

Normosol or equivalent solution 0.5 ml/kg/fasted hr IV (8am to time of induction) of Anesthesia. Maintenance IV Normosol or equiv solution at 6 ml/kg/oper hr. At randomiz to the Liberal arm in the OR, an addit bolus of Normosol or equiv solution 1.5 ml/kg/fasted hr IV (8am to time of induction) will be given to bring the total to Normosol or equiv solution 2ml/kg/fasted hr IV (8am to time of induction). Pt will get an addit bolus of Normosol or equivalent solution 6ml/kg/oper hr. Maintenance IV Normosol or equivalent solution will then commence at 12ml/kg/operative hr with maximum of 1000 ml/operative hr. Blood loss replaced volume: with colloid, until transfusion criteria met (Additional fluid boluses of 100ml Normosol or equivalent solution or bolus pressors (phenylephrine 40mcg or ephedrine 5mg) used at the discretion of the Anes to maintain pt hemodynamic stability. Addit fluid boluses of 250ml Normosol or equivalent solution for urine output less than 1ml/kg for 2 hrs.

To determine if restrictive perioperative fluid management results in fewer complications, morbidity and decreased length of stay in patients undergoing pancreatic resection, compared to liberal fluid management.

Determine if restrictive perioperative fluid management, comp to liberal periop fluid management, decreases delayed gastric emptying, length of stay (LOS) & the incidence of other, less frequent morbidity in adult patients getting pancreatic resection.
