Safety and Efficacy Study of Correcting Hyperglycemia in Patients With Diabetes Having Out-patient Surgery

Phase 4

Withdrawn

• Conditions: Type 1 Diabetes; Type 2 Diabetes
• Interventions: Drug: Regular Insulin; Drug: Humalog

• Registration Number: NCT01971047
• Lead Sponsor: Emory University

Brief Summary

The purpose of this study is to compare the safety and efficacy of intravenous (IV) administration of FDA approved regular human insulin and subcutaneous (SC) administration of humalog, a rapid-acting insulin analog (a synthetic insulin), for correction of hyperglycemia (high blood sugar) during the immediate preoperative period in patients with diabetes having outpatient surgery at the Emory Ambulatory Surgical Center (ASC).

In this randomized controlled clinical trial patients with diabetes will be administered corrective doses of IV regular insulin or SC humalog for preoperative hyperglycemia to determine whether SC humalog results in improved intra and post-operative blood sugar control.The most common current practice at Emory University in the ambulatory surgical setting is IV administration of regular insulin for treatment of pre-operative hyperglycemia. Subjects will not be paid for their participation and will be assured of treatment for their hyperglycemia regardless of study participation.

Detailed Description

Investigators plan to randomize a total of 200 male and female subjects with type 1 and type 2 diabetes,having an out patient surgical procedure, meeting inclusion criteria to receive corrective doses of IV regular insulin (Group I) or SC humalog insulin (Group II). The dosing formula is per Emory University Outpatient Surgical Center protocol for treating hyperglycemia and is the same for both groups. All patients with diabetes will undergo a blood sugar measurement upon arrival to the ASC using the Accuchek blood glucose meter. An admission blood sugar of \>180 in a patient with diabetes qualifies the patient for study screening. Subjects will be approached after confirmation of eligibility for the study. Randomization, then treatment, will occur immediately following written informed consent. Demographic data will be recorded.A medical history with detailed history of diabetes will be obtained and surgical and anesthesia details and length of stay recorded. Blood sugar levels will be checked hourly until the patient is ready for discharge. Subsequent treatment will follow the hyperglycemia protocol. All blood sugar results and doses of insulin will be recorded. The subject's participation will end at the time of discharge from the Ambulatory Surgical Center.

Arm && Interventions

Group	Intervention	Description
Group 1-Regular Insulin	Regular Insulin	Intravenous Regular Insulin will be administered for a preoperative Blood glucose of greater than 180.
Group 2-Humalog	Humalog	Subcutaneous Humalog will be administered for a preoperative Blood glucose of greater than 180

Primary Outcome Measures

Name	Time	Method
BG concentration differences at 1 and 2 hours post intervention and post operatively	one and two hours post intervention, post operative period	Compare the difference in Blood glucose concentration at one and two hours after the administration of corrective doses of regular and humalog insulin and immediately following ambulatory surgery.

Secondary Outcome Measures

Name	Time	Method
Episodes of hypoglycemia	time of intervention to time of patient discharge (an average of three hours, less than one day)	Investigators will assess if there is any difference in the number of hypoglycemic events between the two treatment groups and further assess the rate and frequency of hypoglycemia (\<70 mg/dl) and severe hypoglycemia (\<40 mg/dl).
Number and percentage of target BG readings	From time of treatment until patient discharge (an average of three hours, less than one day)	Investigators will determine the number and percentage of patients in each group with BG readings within the target range ( 80-180 mg/dl)
Episodes of hyperglycemia	time of treatment to time of patient discharge (an average of three hours, less than one day)	Investigators will calculate the number of patients and percent of BG readings with hyperglycemia (\>180 mg/dl) and severe hyperglycemia (\>300 mg/dl)in each group.
Total dose of insulin	time of intervention to time of patient discharge (an average of three hours, less than one day)	Calculate total dosage of insulin administered to each patient
Change in glucose concentration from baseline to one, two and three hours post treatment	time of baseline BG to time of last BG measurement (prior to discharge, less than one day)	Change in glucose concentration from baseline (prior to insulin administration) to one hour, two hours and three hours (if patient present) after insulin administration
Number of perioperative complications	start of surgery to time of patient discharge (less than one day)	Investigators will record the number of perioperative complications (cardiovascular, respiratory or other medical complications) or need for hospital admission
