Diabetic comaAlso known as hyperglycemic hyperosmolar
nonketotic syndrome
serious complication that can happen to a person with type 2 diabetes who is ill or stressed
diabetic coma occurs most often among people who are older than 60.
Most sufferers have a history of diabetes, but for some, the disease is undiagnosed or untreated.

blood sugar gets too high and the body becomes severely dehydrated.
No ketone formed
Death rate – 50%

Investigation Plasma glucoseABGUrea and electrolyteECGCXRUrinanalysis, culture and microscopic
examination
* calculate plasma osmolality2 x (Na + K) + glucose 285 – 295 mOsmol/KgComa = > 400 mOsmol/Kg

Management Aim:
To correct the high osmolality with fluid and insulin over 48-72 hours
Avoid fluid overload (central venous line)

Management Manage as for DKA except:
Initial resuscitation with colloid0.9% saline for fluid replacementIf [Na+] is > 150 mmol/L, use 5% dextroseSlow correction of NaStart insulin at 3 U/hrAnticoagulate

CBD ifSerum creatinine is highOliguria
When blood glucose is <10 mmol/L – 5% dextrose
Stabilized - stop insulin therapy, start OHA or diet control

Hypoglycemic comaDxt
Management :75 ml 20% glucose IV or 1mg glucagon IMOnce recovered give bread or biscuits
Should regain consciousness within 10 minutesIf not repeat blood glucose and consider other cause of
comaAlcohol intox.Post ictal state Cerebral hemorrhage
Consider cerebral edema after blood glucose is restored to normal

Admit if the cause is long –acting SU or long acting insulin
Continuous infusion of 10% dextrose (1L / 8hrly) Check glucose hourly
