In an experimental study on the epigastric venous system of rats, we examined three types of venous flaps with regard to their perfusion and long-term results: arterialised venous flaps, flow-through venous flaps and venous island flaps. We documented afferent and efferent blood flow with radiolabelled substances and blood distribution with infrared thermography. By measuring the surviving flap surfaces after 4 months, the relative success rate for each flap type was determined. ⋯ The venous island flaps had the worst distribution of intravenously injected 125J-Fibrinogen, and it was significantly worse in all types of venous flaps than in standard epigastric flaps; moreover, the clearance of intracutaneously injected 99mTc was the lowest in venous island flaps. The infrared thermographic study showed that the blood in the arterialised venous flaps dispersed faster and over a larger area than in flow-through venous and island flaps. Given these results, we conclude that arterialised venous flaps are the safest form of venous flaps, whereas venous island flaps carry a high risk of partial or total necrosis.

All paediatric scalds admitted in 1991 to the Welsh Centre for Burns and Plastic Surgery have been analysed retrospectively and the results compared with similar studies from this centre reported in 1956 and 1984. This data was compared with similar reports from 6 other world-wide centres. Despite a modest population increase in Wales, the number of admissions has increased almost 50% in 35 years. ⋯ Hot kettles are a common cause of scalds, accounting for up to 28% of scalds in all the series reviewed. The incidence of this injury has not decreased over the last 35 years. Recommendations are made about improved health and safety education for parents, the use of coiled kettle flexes, the temperature of stored water which should not exceed 60 degrees C, and the fitting of thermostatic mixer taps to new houses and institutions, in an effort to decrease the incidence of paediatric scalds.
