ABSTRACT To describe a novel method of safe and effective intensive management of inpatient hyperglycemia with use of cost-effective protocols directed by a glucose management service (GMS).
An intravenous insulin protocol was designed to achieve a glycemic target of 80 to 110 mg/dL. When stable inpatients were transferred from the intravenous protocol to a subcutaneous insulin protocol, which consisted of basal long-acting and prandial and supplemental rapid-acting insulins, the blood glucose target was 80 to 150 mg/dL. Glucose levels were reviewed by the GMS at least daily for protocol adjustments, when necessary.
The intravenous insulin protocol was used in 276 patients, and 4,058 capillary blood glucose levels were recorded. Glycemic target levels (80 to 110 mg/dL) were achieved, on average, 10.6 +/- 5.2 hours after initiation of insulin drip therapy. The mean capillary blood glucose level during the study interval was 135.3 +/- 49.9 mg/dL. Hypoglycemia (< or = 60 mg/dL) was recorded in 1.5% of glucose values, and hyperglycemia (> or = 400 mg/dL) was recorded in only 0.06%. The subcutaneous insulin protocol was used in 922 patients, and 18,067 capillary glucose levels were documented. The mean blood glucose level was 145.6 +/- 55.8 mg/dL during the study period. The blood glucose target of 80 to 150 mg/dL was achieved in 58.6%, whereas 74.3% of glycemic values were in the clinically acceptable range (80 to 180 mg/dL). Hypoglycemia (< or = 60 mg/dL) occurred in 1.3% of capillary blood glucose values, and hyperglycemia (> or = 400 mg/dL) occurred in 0.4% of values.
Validated protocols dedicated to the achievement of strict glycemic goals were implemented by a GMS and resulted in substantial improvements in glycemic control on the surgical inpatient services, with a reduced frequency of hypoglycemia. The protocols and the GMS have been well received by the inpatient nursing and surgical staff members, and all of this has been done in a cost-effective manner.

    ABSTRACT: Poor perioperative glycemic control increases risk of infection, cardiovascular accidents and mortality in patients undergoing surgery. Tight glycemic control by insulin therapy is known to yield better outcomes in such patients. Intravenous (IV) insulin therapy with or without adjunctive subcutaneous insulin therapy is the mainstay of managing hyperglycemia in perioperative period. This observational study assessed the safety of IV Insulin Aspart (IAsp) as compared to Regular Human Insulin (RHI) in patients undergone cardiac surgery at a tertiary care hospital. 203 patients received IV IAsp (n = 103) and RHI (n = 100) respectively. Safety was assessed by frequency and severity of adverse events (AEs) & serious adverse events (SAEs) during hospitalization. IAsp effectively controlled mean blood glucose levels to 159.87 ± 41.41 mg/dl similar to RHI (160.77 ± 44.39 mg/dl). No serious adverse event was reported. The incidence of hypoglycemia was similar in both the groups. The insulin infusion rate, time for which insulin infusion was withheld and mean blood glucose during hypoglycemia was significantly high in RHI group. This study has shown similar safety of IV IAsp as compared to IV RHI in the post cardiac surgery patients. However physicians preferred IAsp as it offers advantage during transition. IV IAsp offers an effective and safe option for managing hyperglycemia in patients in ICU post cardiac procedures.

    ABSTRACT: Hyperglycemia, which occurs in the perioperative period during cardiac surgery, has been shown to be associated with increased morbidity and mortality. The management of perioperative hyperglycemia during coronary artery bypass graft surgery and all cardiac surgical procedures has been the focus of intensive study in recent years. This report will paper the pathophysiology responsible for the detrimental effects of perioperative hyperglycemia during cardiac surgery, show how continuous insulin infusions in the perioperative period have improved outcomes, and discuss the results of trials designed to determine what level of a glycemic control is necessary to achieve optimal clinical outcomes.

    ABSTRACT: Hyperglycemia in the surgical population is a recognized risk factor for postoperative complications; however, there is little literature to date regarding the management of hyperglycemia in the perioperative period. Here, we detail the strategies that our institutions have employed to identify and treat hyperglycemia in patients with diabetes who present for surgery. Our approach focuses on the recognition of hyperglycemia and metabolic abnormalities, control of glucose levels via insulin infusion when needed, monitoring for hypoglycemia and a comprehensive multidisciplinary approach that provides standardized recommendations for patients at all points in care as they transition from the preoperative clinic into the operating room, and then into the hospital.
