in hypertensive emergencies: IV boluses of

intervals, to a maximum of 50 mg.
Can also be given as an infusion: 0.5-1

in pre-ecplamsia for control of BP: 5 mg IV
N. Insulin
Preparation
1. Add 50 units (u) regular insulin to 250cc
Normal Saline (NS)
2. This will make 1u insulin/5cc NS
(0.2u/cc)
Infusion
1. Start at 0.1u/kg/hr (0.5cc/kg/hr)
2. Half life of insulin is approximately 5
minutes
3. Insulin levels return to baseline within
10 minutes of stopping infusion and no
further fall in glucose then occurs
4. Aim for a steady fall in glucose of
approximately 100mg/hr
a. Avoid dropping glucose too
fast
b. It can result in hypoglycemia
and cerebral edema with
herniation (secondary to the
presence of idiogenic osmols in
the brain)
If Glucose is 121 - 150: Give 2 unit bolus
injection and start drip at 2 units/hr.
If Glucose is 151 - 175: Give 3 unit bolus
injection and start drip at 2 units/hr.
If Glucose is 176 - 200: Give 4 unit bolus
injection and start drip at 3 units/hr.
If Glucose is 201 - 250: Give 6 unit bolus
injection and start drip at 3 units/hr.
If Glucose is 251 - 300: Give 8 unit bolus
injection and start drip at 4 units/hr.
If Glucose is 301 - 350: Give 10 unit bolus
injection and start drip at 4 units/hr.
If Glucose is 351 - 400: Give 12 unit bolus
injection and start drip at 5 units/hr.
If Glucose is above 401: Give 15 unit bolus
injection and start drip at 5 units/hr.
Accuchecks q 1 hr. until Glucose is “steadystate” between 80 - 150, then q 2hrs ATC.
