Conclusion
A basal-correction insulin regimen is an alternative method for managing hyperglycemia in non-critically ill surgical patients on PN.
Methods
Retrospective evaluation of a protocol applied during the period of January 2013-December 2015. The insulin dose was started at 0.4 and 0.3 IU/kg/day in patients with previous DM and without a history of DM, respectively, and the target blood glucose (BG) was < 180 mg/dl. Mean BG levels, insulin total daily dose (TDD) and hypoglycemic (< 70 mg/dl) events on different days of PN were also evaluated.
Results
Forty-one patients with previous type 2 DM and 39 without DM were evaluated. Glycemic control in both groups was as follows: during the first 48 h (230.4 ± 67 vs. 189.4 ± 38 mg/dl, p = 0.002); at the midpoint (224.6 ± 58 vs. 181.3 ± 27 mg/dl, p = 0.003); 48 h before ending TPN (196.4 ± 43 vs. 169.8 ± 40 mg/dl, p = 0.004). Insulin TDD was 0.5 ± 0.3 U/kg/day in patients with DM and 0.37 ± 0.3 units/kg/day in those without DM (p < 0.05). A total of 18 patients experienced hypoglycemic events, without differences between the groups.
