Diabetic ketoacidosis during long-term treatment with continuous subcutaneous insulin infusion
NR Peden, JT Braaten and JB McKendry
During 1880 patient-months of treatment with continuous subcutaneous
insulin infusion in 101 patients with IDDM, 36 episodes of acute, severe
loss of glycemic control, including 29 with significant ketoacidosis,
occurred in 20 patients. Fifteen episodes were attributable to failure of
insulin delivery to the patient while 13 were precipitated by infection.
Insufficiently frequent blood glucose monitoring, failure by patients to
detect mechanical and technical problems with infusion systems, failure to
adhere to "sick day" regimens, and delay in seeking medical help all
contributed to the progression of a number of episodes. Thirst, nausea, and
vomiting were the common clinical manifestations of decompensation; and the
degree of acidemia was often mild in relation to the degree of
hyperglycemia. Response to conventional management was usually prompt.
