脑室周围-脑室内出血对早产儿排尿方式的影响

The voiding pattern of premature infant with PIVH

目的探讨脑室周围一脑室内出血（PIVH）对早产儿排尿方式的影响。方法31例胎龄在32-36周适于胎龄早产儿分为两组，正常组16例，胎龄（34．2±1．1）周，日龄（11±2）d；PIVH组15例，胎龄（34．1±1．1）周，日龄（11±1）d进行连续8h自由排尿观察，记录每组早产儿在观察时间内的排尿次数、每次排尿量、残余尿量、清醒排尿及间断排尿，对两组早产儿排尿参数进行统计学分析。结果PIVH组早产儿残余尿量显著高于正常组[（2．4±0．8）ml比（2．0±0．7）m1]（P〈0．05），清醒排尿比例显著低于正常组E（35±6）％比（44±8）％]（P〈0．05），PIVH组与正常组早产儿在观察时间内的排尿次数[（7．4±1．0）比（7．2±1．0）]、每次排尿量[（15．6±5．7）ml比（16．5±6．0）m1]及间断排尿比例（47％比44％）差异均无统计学意义（P〉0．05）。结论脑室周围一脑室内出血对32-36周胎龄早产儿残余尿量及排尿时意识状态具有显著影响，提示脑室周围一脑室内出血早产儿排尿方式与正常早产儿存在差异。

Objective To explore the effect of PIVH on the voiding patterns of premature in-fants. Methods Eight-hourly observations were performed on the voiding patterns of 31 premature in-fants with the gestational ages ranging from 32 to 36 weeks. Of these, 16 infants were without PIVH [-gestation （34. 2 ± 1.1） weeks;post-birth （11 ± 2） days] and 15 patients had PIVH [gestation （34. 1 ± 1.1） weeks; post - birth （11 ± 1） days]. The voiding times, the voiding volume, the residual, the conscious level during voidings and any interruptions at voidings were recorded and analysed. Results There are significant differences between the group with PIVH and the group without PIVH in the re-sidual volumes [（2. 4 ± 0. 8） ml vs. （2. 0 ± 0. 7） ml] and the percentage of patients with conscious voi-ding [（35 ± 6） % vs. （44 ± 8） %] （P〈0. 05）. There was no significant difference in the voiding times [（7. 4 ± 1.0） vs. （7.2 ± 1.0） ,voiding volume （15.6 ± 5.7） ml vs. （16. 5 ± 6. 0） ml] and the percentage of interruption voiding（47% vs. 44%）. Conclusions There is a difference in voiding patterns between infants with PIVH and normal infants.
