Anaesthetic management of total craniopagus twins for magnetic resonance imaging and cerebral angiography.

We describe the anaesthetic management of 4-yr-old total craniopagus twins for radiological investigations. There are some unique anaesthetic problems associated with this condition. These include cross-circulation between the twins that results in induction of both the twins after the administration of i.v. induction agent to one twin and difficulty in mask ventilating both the twins simultaneously due to the angle between the heads; different arterial pressures in the two children complicate pharmacological management and underline the importance of physiological measures to control arterial pressure. Adequate preparation and teamwork is the keystone to the management of these patients.

Surgical experience with congenital heart disease in Down's syndrome.

Children with Down's syndrome and congenital heart defects have multiple problems. The role of cardiac surgery in the management of these patients was investigated by reviewing the clinical data, hospital course and follow-up of 21 patients (9 males and 12 females, age range 1 month to 14 years) with Down's syndrome and congenital heart defects operated in our institute. Twelve (57%) of these were infants and nine (43%), older children. Five were in congestive cardiac failure, four were hypothyroid. The heart lesions ranked in incidence as follows: atrioventricular septal defect 7 (33.3%), tetralogy of Fallot 3 (14.3%), tetralogy of Fallot & atrioventricular septal defect both 2 (9.5%), double outlet right ventricle with pulmonary stenosis 1 (4.8%), patent ductus arteriosus 2 (9.5%), patent ductus arteriosus plus coarctation 1 (4.8%), ventricular septal defect 2 (9.5%), atrial septal defect plus ventricular septal defect 1 (4.8%), atrial septal defect plus patent ductus arteriosus plus right pulmonary artery stenosis 1 (4.8%) and transposition of great arteries with multiple ventricular septal defect 1 (4.8%). Four (19%) patients had palliative procedures while the rest (81%) underwent primary repair. All survived the operation. The post-operative period was complicated in 6 (28.5%), with respiratory infections in 3, pulmonary hypertensive crisis in 2 and complete heart block in 1. The early mortality was 0, while there were 2 (9.5%) late deaths. The number of hospitalisations was markedly reduced according to the parents. Follow-up showed near normal pulmonary artery pressure in 50 percent children with large shunts and a good developmental spurt was seen in 60 percent. From a purely surgical viewpoint, the prognosis for children with Down's syndrome and congenital heart disease is good.

Atrial entrapment of flow directed pulmonary artery catheter-a technique for non-surgical removal.

A 43 year old patient who underwent mitral valve replacement had pulmonary artery catheter inserted before induction of anaesthesia. The catheter could no be removed postoperatively by routine manoeuvres in the intensive care unit. Fluoroscopy in the cardiac catheterization revealed a straight course of the catheter indicating the probability of its inclusion in the left atrial suture line. The pulmonary artery catheter was successfully removed percutaneously in the cardiac catheterization laborartory. The procedure is described.
