Change of the disease constitution of complication in preterm infants of China-Japan friendship Hospital from 2004 to 2009 / 中国综合临床

ABSTRACT

Objective To analyze the change of disease constitution of complications in preterm infants in our hospital and to provide a scientific basis for the clinical prevention and treatment in the future. Methods Two hundred and sixty-eight preterm infants were admitted in NICU of our hospital from Jan. 2004 to Dec. 2009. The constitutions of complications in preterm infants were retrospectively analysed by year. Results One hundred and ninety-seven cases had complications and the incidence of complications was 73.51% ( 197/268 ). The most common complications of preterm infants in our hospital included neonatal hyperbilirubinemia (41. 62% ,82/197), neonatal hypoxic-ischemic encephalopathy (39. 59% , 78/197) and neonatal aspiration syndrome (34. 01%, 67/ 197). The change of disease constitution of the complications were as follows the disease constitution of neonatal hyperbilirubinemia always located within the first 3 diseases ( ranged from 28. 57% to 75.76% , χ2 =13. 582, P < 0. 001) ;the occurrence of neonatal hypoxic-ischemic encephalopathy showed upward trend( increased from 10. 71% to 56. 25% ,χ2 =7. 577,P<0. 001) ,but decreased in 2008,2009;the neonatal aspiration syndrome presented with a high but fluctuant incidence among the 6 years (ranged from 15. 15% to 56. 25% ,x2=12.002,P < 0.001) ; the neonatal hypoglycemia increased in the nearly 3 years;the incidence of neonatal asphyxia was stationary;the disease constitution of neonatal respiratory distress syndrome fluctuated up and down( ranged from 3. 57% to 20.41% ,χ2 = 4. 125,P<0. 05) ;the anemia in premature infant showed upward trend,increasing from 3.03% to 18. 37% (χ2 = 4. 332,P< 0.05 ) ; the occurrence of neonatal scleredema decreased with no statistical significance; the preterm infants suffered from infectious diseases with lower rate. Conclusions The disease constitution of the hospitalized preterm infants in our hospital in the last 6 years is mainly non-infectious diseases. The neonatal asphyxia recovery technology should be further improved. The serum bilirubin concentration should be monitored early after birth of preterm infants and intervened timely. Cranial imaging studies should be performed timely for early detection of brain injury.
