Population Pharmacokinetics of Intramuscular and Intravenous Ketamine in Children.

Ketamine is an N-methyl D-aspartate receptor antagonist used off-label to facilitate dissociative anesthesia in children undergoing invasive procedures. Available for both intravenous and intramuscular administration, ketamine is commonly used when vascular access is limited. Pharmacokinetic (PK) data in children are sparse, and the bioavailability of intramuscular ketamine in children is unknown.

An anthropometric survey of US pre-term and full-term neonates.

Background: Anthropometric data prove valuable for screening and monitoring various medical conditions. In young infants, however, only weight, length and head circumference are represented in publicly accessible databases.

Aim: To characterise length and circumferential measures in pre-term and full-term infants up to 90 days post-natal.
