Arms of the Study

Arm 1

Arm 2

Arm Type

Active Comparator

Placebo Comparator

Arm Label

Metformin

Placebo

Arm Description

Metformin will be administered as pills to be taken orally with an initial dose of 850 mg on the first day; the dose will be increased to 850 mg every 12 hours and 850mg every 8 hours respectively on the second day and then on the days to follow up to the morning of the surgery. Metformin will be discontinued on the day of surgery and will be restarted immediately after surgery.

Placebo will be administered exactly in the similar way to Metformin

Outcomes

Primary Outcome Measures

Change in fasting blood glucose
the level of plasma glucose after 6 hours of fasting

Secondary Outcome Measures

Change in whole body protein balance
The difference between the Pre-operative whole body protein balance( prior to metformin treatment) and the post operative whole body protein balance
Comparing the Homeostasis model assessment (HOMA) index at three different time points ( by employing Fasting blood sugar and Plasma Insulin)
glycosylated Hba1c
plasma level of glycosylated Hba1c
Comparing the pre-operative body impedance and the post operative body impedance (to asses the body composition specifically the amount of body fat)
Measures body composition specifically fat content
Surgical Complications
Any complication related to the surgery with in 30 days post operation
length of hospital stay
Length of hospital stay is calculated as the total length of hospitalization from the date of admission for the purpose of surgery until the date of discharge from the hospital

5. Study Description

Brief Summary
Major surgery results in a stress- induced catabolic response, marked by post-operative insulin resistance, hyperglycemia and loss of body protein, which is associated with increased morbidity, mortality and adverse outcomes. There has been a great deal of research on different approaches to optimize post-operative insulin sensitivity including hormonal and nutritional interventions, minimally invasive surgical techniques and epidural anesthesia. However, the correlation between insulin resistance and body protein loss is not well understood. Metformin is the most widely used insulin sensitizing and blood glucose-lowering drug in treatment of type 2 diabetic patients. This study will: 1) estimate the correlation between insulin resistance and body protein loss in pre-diabetic lung/colorectal resection patients; 2) investigate whether the post-operative metabolic state can be improved by the pre-operative administration of metformin; and assess the impact of metformin on surgical complications and hospital length of stay. The results of this study will provide insight into the relationship between insulin resistance and post-operative adverse events and potentially suggest a novel approach to improve outcomes using Metformin, a drug already in wide clinical use.
