Rectal acetylsalicylic acid was given to 14 children who had undergone open heart surgery. The effect on their temperatures was similar whether 15--30 or 30--50 mg/kg was given. Either dose was more effective than no treatment. The greatest fall in temperature occurred after 4 or 5 hours. Rectal aspirin in a triglyceride base is effective in lowering postoperative temperature. It should also be of use in treating other fevers. A dose of 20--25 mg/kg is suggested.
A new and simple technique is described which clearly defines the aortic anatomy in infantile coarctation. The technique greatly helps to select those neonates whose lives can be salvaged by early surgery. There have been no serious adverse effects.

The effect of bumetanide in infants with congenital heart disease presenting with cardiac failure was studied. The study was divided into acute (3 days) and long-term (mean 10.5 weeks) cases. A total of 12 male infants was included in the acute study and 13 cases were evaluated in the long-term study. The dose used in the acute study (0.015 mg/kg) was suboptimal; notwithstanding it was found to cause significant natriuresis and chloruresis. Bumetanide in doses varying in different infants from as little as 0.015 mg/kg on alternate days to as much as 0.10 mg/kg daily was shown to be an effective diuretic for long-term use. No side effects were observed in either study.
