a Crude relationship between clinically significant weight loss (≥95th percentile) and low vs high doses of ketamine and diazepam. b Crude relationship between neonatal hyperbilirubinemia requiring phototherapy and low vs. high doses of ketamine and diazepam. Low dose ketamine (n = 146) was defined as < 1.16 mg/kg and high dose (n = 147) was ≥1.16 mg/kg maternal body weight. Low dose IV diazepam (n = 92) was defined as < 1 mg/10 kg maternal body weight, and high dose (n = 201) was ≥1 mg/10 kg maternal body weight. a Chi squared test gave p = 0.801 for comparison of low vs high dose ketamine and p = 0.011 for comparison of low vs high dose diazepam. b Chi squared test gave p = 0.478 for ketamine and p = 0.009 for diazepam
