Analysis Of Risk Factors Influencing Hypothermia In Premature Infants

Objective:This experiment is to study the relevant factors that affect hypothermia occurring within 24 hours of preterm infants admitted to hospital.Premature infants temperature affects multiple systems of premature infants.By pre-intervention of relevant factors,it can effectively reduce the complications caused by hypothermia.Methods:A total of 263 preterm infants were collected from the NICU of the First Affiliated Hospital of Wannan Medical College from July 2015 to July 2017.There were 153 males and 110 females.Inclusion criteria for the first Affiliated Hospital of Wannan Medical College Neonatal Intensive Care Unit normal temperature and hypothermia in preterm children,and admitted to hospital and within 24 hours of admission record of body temperature,excluding standard immediately after the death of premature infants admitted to hospital;no Preterm infants with a complete body temperature record within 24 hours;prenatal congenital absence of anus and severe congenital malformations.According to the body temperature records of premature infants admitted to hospital 24,the subjects were divided into hypothermia group(n=160)and normal body temperature group(n=103).And record the birth of the above preterm children:gestational age(early premature infants with early premature children),birth weight(normal birth weight 70 cases,low birth weight 155 cases,very low birth weight 31,low birth weight 7(153 males and 110 females),place of birth(196 births in the hospital and 67 in the hospital),number of births(single 165,multiple births in 98),asphyxia(asphyxia without asphyxia 54 cases),neonatal respiratory distress syndrome(no DRS159 cases,DRS104 cases),neonatal infection(no infection 152,infection 111);maternal perinatal conditions:the mother's age(age<35 years 189 cases,age?35 years of age,74 cases),gestational hypertension(no pregnancy-induced hypertension in 215 cases,gestational hypertension in 48 cases),gestational diabetes(no gestational diabetes in 236 cases,gestational diabetes mellitus in 27 cases),premature rupture of membranes Broken(no premature rupture of membrane in 132 cases with premature rupture of membranes in 131 cases).The above-mentioned related risk factors were analyzed by Pearson's single factor and binary logistic regression model respectively,P<0.05 was statistically significant.Results:.Pearson univariate analysis of hypothermia affecting preterm infants:Prenatal births:gestational age,birth weight,sex,place of birth,number of births,neonatal asphyxia,neonatal respiratory distress syndrome;maternal perinatal status:age of mother(?~2=33.408,P<0.000),birth weight(?~2=41.106,P<0.000),and gender gender,age at birth,(?~2=0.692,P<0.120),place of birth(?~2=22.168,P<0.000),number of births(?~2=0.179,P<0.384),neonatal asphyxia(?~22=19.578,P<0.000),respiratory distress syndrome(?~2=0.518,P<0.287),gestational diabetes mellitus(?~2=0.352,P<0.346),premature rupture of membranes(?~2=0.109,P<0.420).There were significant differences in gestational age,birth weight,place of birth,neonatal asphyxia,respiratory distress syndrome in preterm infants and maternal age(P<0.05).Binary Logistic regression analysis of risk factors related to hypothermia in preterm infants showed that the risk factors of gestational age(OR=2.686),birth weight(OR=1.677),place of birth(OR=4.060),neonatal asphyxia=3.911),maternal age(OR=1.720)neonatal respiratory distress syndrome(OR=1.331).The gestational age,birth weight,birth place and neonatal asphyxia were the risk factors for hypothermia in preterm infants.Conclusion:1.Premature infants admitted to hospital within 24 hours of hypothermia and a variety of factors,the most important risk factors are:gestational age,birth weight,place of birth,suffocation.2.For the appropriate risk factors to take a reasonable and effective method for effective prevention and treatment of complications caused by hypothermia provide a theoretical basis.
