Study Arms (2)
Naloxone
EXPERIMENTALThe naloxone arm of the study will receive naloxone at a rate of 5mcg/kg/hr which equates to 0.25ml/kg/hr. Each 1 ml ampoule of solution contains 400 micrograms (0.4mg) naloxone hydrochloride present as naloxone hydrochloride dihydrate. Excipients: each 1ml contains 3.55mg sodium. This will be diluted to a concentration of 20mcg/ml with 0.9% NaCl. Presented as solution for injection or infusion. Clear colourless sterile solution.
Saline
PLACEBO COMPARATORThe placebo arm of the study will receive an infusion of normal saline at a rate of 0.25ml/kg/hr.
