Consensus regarding optimal glucagon dosing for management or diagnosis of neonatal/infant hypoglycemia has not been established.
To investigate glycemic effects of glucagon dosed ≤0.2 mg/kg (Gnlow) vs. >0.2 mg/kg (Gnhigh) in neonatal/infant hypoglycemia.
Retrospective, observational, cohort study.
Glucagon administration at any dose resulted in 75/77 (97.4%) samples meeting criteria for normoglycemia (plasma glucose >60 mg/dL), and plasma glucose increases of >30 mg/dL occurred in 74.2% vs. 63% (NS) of samples in the Gnlow and Gnhigh groups, respectively. Despite equivalent glucagon dosing, there was a trend toward smaller (<2500 g) patients achieving post-glucagon plasma glucose increases of >30 mg/dL less often than their bigger (≥2500 g) counterparts (60% vs. 74.1%, NS).
Glucagon is highly effective in raising plasma glucose levels in neonatal/infant hypoglycemia. No differences in glycemic effects were noted between either dosing regimen. However, glycemic effects may be diminished in lower weight patients.
