title: Caesarean section for twins in a patient with myotonic dystrophy.
abstract: The management of a patient with myotonic dystrophy undergoing Caesarean section for delivery of twins in breech position is reported. Anaesthetic management must reflect the multi-system nature of the disease in addition to the implications of pregnancy. Known triggers of myotonic crisis (succinylcholine, shivering) must be avoided. Attention to respiratory reserve is necessary in view of the restrictive defect this disease can impose. Cardiomyopathy and conduction system disturbances may be features. Upper gastrointestinal incoordination can superimpose the added risk of aspiration on the pregnant myotonic. Ineffective uterine contraction can cause vigorous post partum haemorrhage. Endocrine disturbances, especially diabetes mellitis, may be present. There may be increased sensitivity to sedative and narcotic agents. The newborn myotonic will need the expertise of neonatal care.
