Pre-operative Carbohydrate Drink to Preserve Peri-operative Insulin Sensitivity

Not Applicable
Completed
Conditions
Laparoscopic Abdominal Surgery
Interventions
Dietary Supplement: complex carbohydrate drink
Dietary Supplement: simple carbohydrate drink
Registration Number
NCT02673502
Lead Sponsor
McGill University Health Centre/Research Institute of the McGill University Health Centre
Brief Summary

Enhanced Recovery after Surgery (ERAS) pathways include multiple evidence-based interventions delivered throughout the peri-operative period that aim to attenuate the surgical stress response and support rapid physiologic and functional recovery.A key element of the ERAS pathway is the administration of a clear carbohydrate-rich beverage 2-3 h before surgery in order to keep the patient in a fed state rather than a fasted state when they go to the operating room. The aim of the current study is to investigate the impact of a drink containing simple carbohydrate on attenuating surgical stress induced insulin resistance in patients undergoing major laparoscopic abdominal surgery, compared to drinks containing maltodextrin.

complex carbohydrate drinkcomplex carbohydrate drinkPatients will ingest 400 ml of the complex carbohydrate drink containing 50 grams of maltodextrin powder in water ( orange food color and artificial orange flavor have been added to the drink) 2 hours before surgery.

Primary Outcome Measures
NameTimeMethod
difference in insulin resistanceIntra-operative from beginning of surgical procedure until the end of the procedure

intra-operative insulin resistance as assessed by glucose infusion rate required to maintain euglycemic state during a hyperinsulinemic euglycemic glucose clamp

Secondary Outcome Measures
NameTimeMethod
Comparing the Homeostasis model assessment (HOMA) index at four different time points ( by employing Fasting blood sugar and Plasma Insulin)at 4 time points as follow : on the morning before surgery, first, second and third morning after the surgery
Comparing the preoperative thirstTwo times at 2 weeks before surgery (baseline) and immediately before surgery

Patients will complete a standard 10mm visual analogue scale (VAS) for each of the measures by marking the level on the scale at baseline in the pre-op clinic visit and once more immediately before surgery.

Comparing the preoperative hungerTwo times at 2 weeks before surgery (baseline) and immediately before surgery

Patients will complete a standard 10mm visual analogue scale (VAS) for each of the measures by marking the level on the scale at baseline in the pre-op clinic visit and once more immediately before surgery.

Comparing the preoperative well-beingTwo times at 2 weeks before surgery (baseline) and immediately before surgery

Patients will complete a standard 10mm visual analogue scale (VAS) for each of the measures by marking the level on the scale at baseline in the pre-op clinic visit and once more immediately before surgery.

Comparing the preoperative anxietyTwo times at 2 weeks before surgery (baseline) and immediately before surgery

Patients will complete a standard 10mm visual analogue scale (VAS) for each of the measures by marking the level on the scale at baseline in the pre-op clinic visit and once more immediately before surgery.

Grip strengthTwo times at 2 weeks before surgery (baseline) and 2 days after surgery

will be measured by a hand grip dynamometer

Time to readiness for discharge (TRD)up to 30 days after surgery

Previously described criteria to determine the time to readiness for discharge after colorectal surgery will be used . These criteria include tolerance of oral intake, recovery of lower gastro intestinal function, achieving adequate pain control, ability to mobilize and perform self-care and clinical/lab results showing no complications or untreated medical problems.

Postoperative infectious complications30 days after operation

Including urinary tract infection, wound infection, intra- or retroperitoneal abscess, pneumonia , sepsis and any other documented infectious complications
