Q

What are the five main side effects of insulin?

A
Hypoglycemia (most serious side effect) and the first symptoms are compensatory effects of increased epinephrine secretion (diaphoresis, tachycardia, HTN) 
Allergic reactions
Lipodystrophy
Insulin resistance

16
Q

Metformin does not

A

Undergo metabolism!

17
Q

The mechanism of action of metformin is

A

It activates adenosine monophosphate activated protein kinases

18
Q

Metformin should be

A

Discontinued 48 hours prior to surgery and should not be administered in patients with hepatic dysfunction, renal insufficiency, IV contrast dye, acute MI, CHF arterial hypoxemia and sepsis

19
Q

Sulfonylureas should not

A

Be administered to patients with sulfa allergy

20
Q

Secretagogues

A

Include sulfonylureas and meglitinides increase insulin availability

21
Q

Biguanides

A

Include metformin and it suppresses excessive hepatic glucose release

22
Q

Thiazolidinediones or glitazones

A

Include rosiglitazone and pioglitazone and they improve insulin sensitivity

23
Q

Alpha glucosidase inhibitors include

A

Acarbose and Miglio ok and they delay GI glucose absorption (used to maintain glucose control)

24
Q

With sulfonylurea oral hypoglycemics

A

Hypoglycemia while infrequent is more often prolonged and more dangerous than hypoglycemia from insulin

25
Q

Sulfonylureas close

A

K-ATPase channels and inhibit ischemic preconditioning (CV mortality has been associated with sulfonylureas)

26
Q

Accumulation of active metabolites

A

May cause hypoglycemia with nateglinide

27
Q

Acarbose and Miglitol work by

A

Decreasing carbohydrate digestion and absorption of dissachardies by interfering with intestinal glucosidase activity

28
Q

Thiazolidinediones work by

A

Decreasing insulin resistance and hepatic glucose production and increase use of glucose by the liver

29
Q

Glucagon like peptide 1 receptor agonists

A

Increase insulin secretion from beta cells (glucose dependent)

30
Q

Amylon agonists

A

Do not alter insulin levels and instead readied HBA1 C

31
Q

The goal of combination therapy is:

A

Decrease hba1c, decrease in daily insulin dose

32
Q

Diabetic autonomic neuropathy is

A

Decreased ability to compensate/risk of CV stability/ sudden cardiac death

33
Q

Diabetic patients should be

A

Assessed for temporomandibular joint and cervical spine mobility to assess difficult intubation

34
Q

Glucose levels should be kept less than

A

180 mg/dL Intraop

35
Q

AM dose of regular insulin

A

Should be held on the day of the surgery

36
Q

Plasma glucose should be monitored

A

Q30 minutes or hourly

37
Q

What drugs should be discontinued 24-48 hours before surgery?

A

Sulfonylureas and metformin due to long half lives
