Abstract:
Objective:To study the influence of phototherapy time on the buttock skin temperature and to discuss the effect of early warning intervention in preventing the buttock skin damage.
Methods:Select 100 cases of jaundice in hospitalized neonates in Neonatal Department of the First People's Hospital of Wujiang from January to April 2014 and divide them randomly into conventional group and experimental group with 50 cases in each.The two groups were given routine nursing，and the same treatment.The buttock skin of the conventional group was protected by 3M painless protective membrane，while the experimental group was given 3M painless protective membrane protection before phototherapy and was post the artificial skin protection along the ischial tuberosity to anal Monday circle，with 3M 9534HP film coating protection outside the artificial skin. Measure the buttock skin temperature of the two groups before phototherapy and 2 hours，4 hours，6 hours and 8 hours after phototherapy.Record the incidence of buttock skin damage in the two groups.
Results:Body temperature before phototherapy，2 hours and 4 hours after phototherapy of the two groups had no significant difference(P＞0.05).However body temperature of 6 hours and 8 hours after phototherapy of the conventional group were higher than that of the experimental group，which had statistical significance(P＜0.05).Body temperature in each time period of 2 hours，4 hours，6 hours and 8 hours after phototherapy of the two groups were higher than that before phototherapy(P＜0.01).The incidence rate of the buttock skin damage after the early warning intervention of the experimental group was 2%（1/50），which was significantly better than the conventional group［16%（8/50）］，the difference having statistical significance（P＜0.05）.
Conclusion:Phototherapy causes the buttock skin temperature to rise and the incidence rate of buttock skin damage is reduced after the early warning intervention.
