“…The way sedation and general anaesthesia is organised depends largely on local agreements and legislations. The drugs most frequently used for sedation are oral chloral hydrate and intravenous pentobarbital sodium (American Society of Anesthesiologists Task Force,1996;Bisset & Ball,1991;Committee on Drugs,1992;Cote,1994;Frush et al,1996;Pereira et al,1993;Strain, 1988;Nievelstein,2010).Oral chloral hydrate, 50 to 100 mg/kg, with a maximum dosage of 2000 mg, is the drug of choice for children younger than 18 months. Intravenous pentobarbital sodium, 6 mg/kg with a maximum dose of 200 mg, is advocated in children older than 18 months.…”
