ABSTRACT
Objective@#To investigate the correlation of early incubator temperature fluctuation on intraventricular hemorrhage (IVH) in very/extremely-low birth weight infants (E/VLBW).@*Methods@#From July 2015 to September 2016, 270 patients of hospitalized E/VLBW were included in this study. Temperature changes including incubator temperature and abdominal temperature within 72 hours after admission and routine clinical data were collected,the E/VLBW were divided into IVH group and non-IVH group, as well as the occurrence and grading of IVH. Chi-square test, t test and nonparametric test and logistic regression analysis were used to explore the effect of early incubator temperature fluctuations in E/VLBW on IVH.@*Results@#Of the 270 V/ELBW studied, the incidence of IVH was 24.4% (66/270) , severe IVH(grade Ⅲ and Ⅳ) was 5.2% (14/270) . Univariate analysis showed that in addition to common IVH risk factors such as gestational age, body weight, 1/5 min Apgar score, sex, delivery, hyperglycemia, prenatal steroid and mechanical ventilation, fluctuations of body temperature and incubator temperature were relevant for IVH in E/VLBW (P<0.05) . Logistic regression analysis of the above relevant risk factors showed fluctuations of temperature (OR=1.10) was also an independent risk factor for IVH in E/VLBW(P<0.05) , in addition to sex(OR=0.42) , 1 min Apgar score (OR=0.71) , and hyperglycemia (OR=3.67) .@*Conclusion@#Fluctuation of incubator temperature is an independent risk factor for IVH in V/ELBWI. During centralized nursing and nursing operations, the operating time should be shortened as much as possible to reduce the number of fluctuations of incubators and body temperature to reduce the incidence of IVH and improve the quality of life.

Methods From July 2015 to September 2016, 270 patients of hospitalized E/VLBW were included in this study.

Chi-square test, t test and nonparametric test and logistic regression analysis were used to explore the effect of early incubator temperature fluctuations in E/VLBW on IVH. Results Of the 270 V/ELBW studied, the incidence of IVH was 24.4%(66/270), severe IVH(gradeⅢandⅣ) was 5.2%(14/270). Univariate analysis showed that in addition to common IVH risk factors such as gestational age, body weight, 1/5 min Apgar score, sex, delivery, hyperglycemia, prenatal steroid and mechanical ventilation, fluctuations of body temperature and incubator temperature were relevant for IVH in E/VLBW (P＜0.05). Logistic regression analysis of the above relevant risk factors showed fluctuations of temperature ( OR=1.10)was also an independent risk factor for IVH in E/VLBW( P＜0.05), in addition to sex( OR=0.42), 1 min Apgar score ( OR=0.71), and hyperglycemia ( OR= 3.67). Conclusion Fluctuation of incubator temperature is an independent risk factor for IVH in V/ELBWI. During centralized nursing and nursing operations, the operating time should be shortened as much as possible to reduce the number of fluctuations of incubators and body temperature to reduce the incidence of IVH and improve the quality of life.
