[The heating effect of two infusion warmers].

An investigation was performed to compare the Animec infusion warmer with the Fenwall infusion warmer. The maximal increase in temperature for the Animec infusion warmer was 8.9 degrees C and this was recorded with a flow of 395 ml/hour. The values for the Fenwall infusion warmer were 12.0 degrees C with a flow of 1,527 ml/hour. An estimate is made of the reduced energy deficit with employment of the two infusion warmers. It is concluded that supply of energy to the infusion warmers. It is concluded that supply of energy to the infusion fluid depends on the flow of fluid through the infusion warmer and the capacity of the infusion warmer. Great differences were observed in the capacities of the two infusion warmers to compensate for the peroperative energy deficit at the rates of flow normally recommended.
