Abstract

Generally, premature infants are placed in prone position in the incubators so that such advantages may be offered as the minimized risk of respiratory inhibition and the reduced volume of residual milk in stomach. On the contrary, this body position not only hampers the successful collection of a necessary volume of urine in many cases but also may cause dermatitis. e.g., rubor, in some cases. In this study, we developed a new urine collection method (hereafter. simply referred to as Method B), in which a space was left around a piece of sponge in a urine collecting bag. and compared it with the conventional method (hereafter. simply referred to as Method A) for evaluating its usefulness. The comparison revealed that the rates of urine co1lection for both male and female infant groups were significantly higher (Pc0.05 for both groups) in Method B than those in Method A. Urine leakage was observed when the urine collecting bag was detached from the infant or dislocated from its original position in most cases. In Method B. the number of cases of urine leakage. was significantly less (P<0.01) than that in Method A. and the urine collecting bag could be easily replaced in position. For this reason. it may be reasonably considered that Method B improved the rates of urine collection. In addition. it was suggested that Method B with a space left around a piece of sponge in the urine collecting bag facilitated easier urine collection into the bottom of the bag compared with Method A even if a urine flow toward the bottom was obstructed, resulting in higher rates of urine collection even in prone position. The fact that no dermatitis was observed. e.g.. rubor. in Method B demonstrated that the use of a piece of sponge in the urine collecting bag also had an effect on prevention of dermatitis. We will make a further study on the improved version of Method B, in which a new technique for attaching the bag firmly to the infants and forcing a urine flow into the bottom of the bag with no obstruction is to be developed. ...
