Randomized Controlled Trial Multicenter Study Comparative Study
Does intraosseous equal intravenous? A pharmacokinetic study.
Despite the growing popularity of intraosseous infusion for adults in emergency medicine, to date there has been little research on the pharmacokinetics of intraosseously administered medications in humans. The objective of the study was to compare the pharmacokinetics of intraosseous vs intravenous administration of morphine sulfate in adults. ⋯ The results support the bioequivalence of intraosseous and intravenous administration of morphine sulfate in adults.

Capillary refill time (CRT) has been taught as a rapid indicator of circulatory status. The aim of this study was to define normal CRT in the Australian context and the environmental, patient, and drug factors that influence it. ⋯ Capillary refill time varies with environmental and patient factors, but these account for only a small proportion of the variability observed. Its suitability as a reliable clinical test is doubtful.
