Early changes in body temperature of children with congenital heart disease after surgical operation

Objective To describe the temperature variation within 24 h of the children with congenital heart disease after open heart surgery , the incidence of fever and the relation between fever and clinical outcome, aiming to provide basis for clinical nursing .Methods The convenience sampling method was used to select 200 cases of children with congenital heart disease after open heart operation , collecting body temperature within postoperative 24 hours and clinical outcomes .Results The body temperature of children reached the peak after three hours of open heart operation , then it began to slow down .The fever rate of early postoperative period （within 24 h） was 63.5%.The demographic data of fever group （≥38.0 ℃） and no fever group （〈38.0℃） had no significant difference（P〉0.05）, except for the aspect of clinical diagnosis （χ2 =10.641, P=0.001）.The median of ICU stay length, the ventilation time and the total length of hospital stay in fever group and no fever group were 68.50 h and 46.00 h, 20.00 h and 16.00 h, 16.00 d and 12.00 d, which were significantly different （Z =-1.971,-1.998,-3.700, respectively;P〈0.05）.Conclusions The body temperatures of children with congenital heart disease after open heart operation reach the peak after three hours . More than half of postoperative children will appear postoperative fever , which could affect the clinical outcome .
