In 1992, the USA Food and Drug Administration (FDA) issued a warning in the Scoline® (suxamethonium chloride, GlaxoSmithKline, USA) package insert after receiving reports of intractable cardiac arrests.1 It stated: "Since there may be no signs or symptoms to alert the practitioner as to which patients are at risk, it is recommended that the use of succinylcholine in children should be reserved for emergency intubation or instances where immediate securing of the airway is necessary, e.g. laryngospasm, difficult airway, full stomach or intramuscular (IM) use when a suitable vein is inaccessible." Scoline® has been used for rapid sequence tracheal intubation since its introduction into clinical practice in Europe in 1951 and in the USA in 1952.2 It gained popularity for its quick onset (less than 60 seconds) and ultrashort duration of action. Scoline® came to rule the practice of anaesthesia and continues to do so even today. It is the gold standard against which the other muscle relaxants are compared;3 however, a number of clinical case reports have shown clearly that the use of scoline has been associated with a number of serious adverse effects4,5 and its use has declined since 1992.
