To determine whether using mechanical ventilation in neonatal intensive care unit (NICU) influences motor development of low birth weight (LBW) infants and to compare their motor development with normal birth weight (NBW) infants at the age of 8 to 12 months using Peabody Developmental Motor Scale 2 (PDMS-2).
This cross sectional study was conducted on 70 LBW infants in two groups, mechanical ventilation (MV) group, n=35 and without mechanical ventilation (WMV) group, n=35 and 40 healthy NBW infants matched with LBW group for age. Motor quotients were determined using PDMS-2 and compared in all groups using ANOVA statistical method and SPSS version 17.
Comparison of the mean developmental motor quotient (DMQ) of both MV and WMV groups showed significant differences with NBW group (p< 0.05). Also, significant difference was found between the gross DMQ of MV group and WMV group (p< 0.05). Moreover, in MV group, both gross and fine motor quotients were considered as below average (16.12%). In WMV group, the gross motor quotient was considered as average (49.51%) and the fine motor quotient was considered as below average (16.12%).
It seems that LBW infants have poor fine motor outcomes. The gross motor outcomes, on the other hand, will be significantly more influenced by using mechanical ventilation. In addition, more differences seem to be related to lower birth weight. Very Low Birth Weight (VLBW) infants are more prone to developmental difficulties than LBW infants with the history of using mechanical ventilation especially in fine motor development.
确定新生儿重症监护病房（NICU）中使用机械通气是否会影响低出生体重（LBW）婴儿的运动发育，并使用皮博迪发育运动量表第二版（PDMS - 2）比较其与正常出生体重（NBW）婴儿在8至12个月龄时的运动发育情况。
本横断面研究对70名LBW婴儿进行了分组，机械通气（MV）组，n = 35；非机械通气（WMV）组，n = 35；以及40名与LBW组年龄匹配的健康NBW婴儿。使用PDMS - 2确定运动商，并使用方差分析统计方法和SPSS 17版在所有组中进行比较。
MV组和WMV组的平均发育运动商（DMQ）与NBW组相比均有显著差异（p < 0.05）。此外，MV组和WMV组的粗大运动DMQ之间也存在显著差异（p < 0.05）。此外，在MV组中，粗大运动商和精细运动商均被认为低于平均水平（16.12%）。在WMV组中，粗大运动商被认为处于平均水平（49.51%），而精细运动商被认为低于平均水平（16.12%）。
似乎LBW婴儿的精细运动结果较差。另一方面，粗大运动结果将受到机械通气的显著影响。此外，更多差异似乎与较低的出生体重有关。极低出生体重（VLBW）婴儿比有机械通气史的LBW婴儿更容易出现发育困难，尤其是在精细运动发育方面。
