NCT00905502

Brief Summary

The objective of this study is to evaluate the effects of 'high' versus 'low' volume intraoperative fluid administration (Ringer Lactate, RL) on intra- and postoperative parameters, in obese patients undergoing laparoscopic bariatric surgery (i.e., gastric bypass), in order to establish evidence-based data for perioperative fluid management in this patient population. Based on their experience as well as several reports in the literature, the investigators hypothesized that a restrictive approach to intraoperative hydration will reduce the incidence of postoperative complications and the recovery time of gastrointestinal (GI) function, and shorten hospital stay.

Outcome Measures

Primary Outcomes (1)

  • postoperative complications: mortality and morbidity (including readmissions)

    30 postoperative days (PODs)

Secondary Outcomes (4)

  • GI recovery: time until the patient resumed drinking and consuming soft food

    3 PODs

  • length of hospital stay

    postoperative period

  • differences in hematocrit, creatinine concentrations and oxygen saturation in the first and third postoperative days and with discharge

    primary hospitalization

  • the number of patients receiving transfusion of blood and blood products

    3 PODs
