Glucose Control in Severely Burned Patients
2022年3月24日 更新者:Dr. Marc Jeschke、Sunnybrook Health Sciences Centre
Glucose Control in Severely Burned Patients: Mechanisms and Therapeutic Potential
The central aim of this application is to determine whether improved outcomes with tight euglycemic control are due to insulin-specific responses.
The investigators hypothesize that improving insulin resistance will lead to decreased inflammatory and hypermetabolic responses, as well as restored glucose metabolism, and so result in improved clinical outcome of severely burned patients.

武器和干预
参与者组/臂 |
干预/治疗 |
|---|---|
|
无干预:控制
|
|
|
实验性的:二甲双胍
|
Metformin 850 mg q. 8 hours will be given to decrease blood glucose to 130-140 mg/dl.
|
|
实验性的:Insulin
|
Humulin R (U-100) will be given i.v.
The dose given will be adjusted in order to achieve a blood glucose level of 130-140 mg/dl.

研究衡量的是什么?
主要结果指标
结果测量 |
措施说明 |
大体时间 |
|---|---|---|
|
Perform oral glucose tolerance test
大体时间:at 1-2 months post-admission, up to 6 months
|
Standard fasting oral glucose tolerance test with an intake of 75 g of glucose.
Subsequent measurements (in mg/dl) of glucose in blood, insulin and c-peptide will be conducted over 2 hours.
|
at 1-2 months post-admission, up to 6 months
|
|
Perform oral glucose tolerance test
大体时间:assessed at discharge (1-4 months post admission depending on the severity of injury)
|
Standard fasting oral glucose tolerance test with an intake of 75 g of glucose.
Subsequent measurements (in mg/dl) of glucose in blood, insulin and c-peptide will be conducted over 2 hours.
|
assessed at discharge (1-4 months post admission depending on the severity of injury)

次要结果测量
结果测量 |
措施说明 |
大体时间 |
|---|---|---|
|
Measure concentrations of serum cytokines
大体时间:weekly until discharge (1-4 months post admission depending on severity of injury)
|
Inflammatory response will be assessed by measuring the concentrations (in pg/ml)of a panel of serum cytokines (IL-1, IFN, TNF etc.) using the Bio-Plex 17-Plex Suspension assay.
|
weekly until discharge (1-4 months post admission depending on severity of injury)
|
|
Record the episodes of sepsis
大体时间:daily until discharge (1-4 months post admission depending on severity of injury)
|
Patients will be assessed daily for episodes of sepsis.
The total number of episodes over the course of hospital stay will be recorded.
|
daily until discharge (1-4 months post admission depending on severity of injury)
|
|
Record the episodes of Pneumonia
大体时间:daily until discharge (1-4 months post admission depending on severity of injury)
|
Pneumonia is defined by new progressive and persistent infiltrate, consolidation or cavitations, inhalation injury based on chest X-ray.
We will also follow the guidelines provided by the American Burn Association on the definition of Pneumonia in burn patients.
Change in sputum (purulent or increased) will also be recorded.
