Scientific titleDoes intra-operative goal directed fluid therapy (GDT) alter microvascular circulation and reduce clinically important post-operative complications in patients undergoing elective major abdominal surgery?
Study acronymMIDAS
Study hypothesisRCT of algorithm driven intraoperative goal directed vs standard fluid therapy during major rectal and urological surgery. Uncalibrated pulse power analysis (LiDCO rapid) used to quantify nomincal cardiac stroke volume. Prior to surgery patients separated into aerobically fit and unfit strata by performance on cardiopulmonary exercise test. clinical outcome is Day 5 POMS (complications ) score. Perioperative microcirculatory changes also
Ethics approval(s)ref: 10/H0203/68
ConditionAnaesthetics
InterventionGoal directed fluid therapy, supplementary gelatin colloid boluses delivered by investigator according to algorithm based on stroke volume variablity and stroke volume as shown by LiDCO rapid;
Follow Up Length: 3 month(s)
Intervention typeProcedure/Surgery
Primary outcome measureProfile of Mood States (POMS) score measured at Day 5
Secondary outcome measuresMicrovascular indices measured at baseline, post induction,end operative and on day 1 post operative
