目的评估极低出生体重儿和极早早产儿随访到1岁时的体格发育状况、呼吸道感染频率及就诊频率等情况。方法将2008年5月至2009年5月四川大学华西第二医院新生儿科收治并存活出院的孕周小于32周或产重小于1500g的72例新生活产婴儿分为3组:第一组26例,孕周<32周而产重≥1500g;第二组18例,孕周≥32周而产重<1500g;第三组28例,孕周<32周且产重<1500g。于校正胎龄1岁时收集生长状况、呼吸道感染频率及就诊次数等信息。结果出院后随访到1岁时,第三组体重、头围的落后率高于第一组,身长的落后率高于第一组和第二组;第三组的中位呼吸道感染频率(15.5)较第一组(12.5)和第二组(8.5)高,第三组中位就诊次数(27.5)比第一组(17.5)和第二组(15.5)高。结论本研究结果提示,校正胎龄1岁时同是极低出生体重儿和极小胎龄早产儿的随访情况较仅为极低出生体重或极小胎龄的患儿要差,因此,胎龄和产重在评估早产儿预后方面同样重要。
Objective To assess the physical development status, respiratory infection frequency and frequency of visits of very low birth weight infants and very early preterm children up to the age of 1. Methods Seventy-two newborn infants born less than 1 week old and weighing less than 32 weeks gestational age and having been discharged from the Department of Neonatology, Second West China Hospital, Sichuan University from May 2008 to May 2009 were divided into three groups: Group 1 Cases, gestational age <32 weeks and weight ≥ 1500g; the second group of 18 cases, gestational weeks ≥ 32 weeks and the birth weight <1500g; the third group of 28 cases, gestational weeks <32 weeks and the birth weight <1500g. At the age of 1 corrected gestational age to collect growth status, respiratory infection frequency and number of visits and other information. Results After follow-up to 1 year after discharge, the backwardness of body weight and head circumference in the third group was higher than that of the first group, and the backwardness of the height was higher than those in the first and second groups. The third group had a median respiratory infection frequency of 15.5 ) Was higher than those of the first group (12.5) and the second group (8.5), and the median number of visits in the third group (27.5) was higher than the first group (17.5) and the second group (15.5). Conclusions Our results suggest that follow-up to very low birth weight infants and very small gestational age preterm infants at 1 year of corrected gestational age is worse than in those with only very low birth weight or very small gestational age, and therefore fetal Age and weight are equally important in assessing the prognosis of preterm infants.
