Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

For non-diabetic patients undergoing gastrointestinal surgery, preoperative oral carbohydrate improves postoperative recovery. The purpose of this pilot study is to investigate the impact of preoperative oral carbohydrate (outfast®) on the recovery in diabetic patients after gastrointestinal surgery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Studies show that avoiding long-time fasting by oral carbohydrates 2 hours before surgery attenuates discomfort and anxiety; it also reduces stress, insulin resistance and catabolism in patients undergoing gastrointestinal surgery, resulting in earlier recovery of gastrointestinal function and short length of hospital stay after surgery. However, for diabetic patients scheduled to undergo gastrointestinal surgery, the risks and benefits of preopertive oral carbohydrate remain unclear. The purpose of this pilot study is to investigate the impact of preoperative oral carbohydrate (outfast®) on the recovery in diabetic patients after gastrointestinal surgery.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intervention group

For all patients, 2 bottles of oral carbohydrate (Outfast, 710 ml) is provided between 22:00-24:00 on the day before surgery. Subcutaneous insulin is administered before drinking.

For patients who entered operating room before 12:00, 1 bottle of oral carbohydrate (Outfast) is provided at 6:00 on the day of surgery. For patients who enter the operating room after 12:00, another bottle of oral carbohydrate (Outfast) is provided at least 2 hours before entering the operating room. Subcutaneous insulin is administered before drinking.

Group Type EXPERIMENTAL

Oral carbohydrate (Outfast)

Intervention Type DIETARY_SUPPLEMENT

For all patients, 2 bottles of oral carbohydrate (Outfast, 710 ml) is provided between 22:00-24:00 on the day before surgery. Subcutaneous insulin is administered before drinking. The dose of insulin is calculated by an endocrinologist according to patients' daily glucose controlling plan.

For patients who entered operating room before 12:00, 1 bottle of oral carbohydrate (Outfast) is provided at 6:00 on the day of surgery. For patients who enter the operating room after 12:00, another bottle of oral carbohydrate (Outfast) is provided at least 2 hours before entering the operating room. Subcutaneous insulin is administered before drinking. The dose of insulin is calculated is the same way as described above.

Control group

For all patients, routine fasting (drinking water allowed) begins from 22:00 on the day before surgery, water fasting begins from 6:00 on the day of surgery.

For patients who enter the operating room before 12:00, no oral or intravenoous fluid is provided from 6:00. For patients who enter the operating room after 12:00, 5% glucose (500-1000 ml) is provided by intravenous infusion from 6:00 on the day of surgery. Intravenous insulin is added (glucose:insulin=4-6:1). Electrolytes (such as sodium chloride, potasium chloride, magnesium sulfate) are added when becessary.

Group Type SHAM_COMPARATOR

Routine fasting

Intervention Type OTHER

For all patients, routine fasting (water drinking allowed) begin from 22:00 on the day before surgery until entering the operating room on the day of surgery.

For patients who enter the operating room before 12:00, no oral or intravenoous fluid is provided. For patients who enter the operating room after 12:00, 5% glucose (500-1000 ml) is provided by intravenous infusion from 6:00 on the day of surgery. Intravenous insulin is added in the 5% glucose (glucose:insulin=4-6:1). Electrolytes (such as sodium chloride, potasium chloride, and magnesium sulfate) are added when considered necessary.
