To investigate the clinical effect of the application of position management in preschool children in child intensive care unit ( PICU).

100 critically ill preschoolers treated in the PICU from April to December, 2018 were randomly divided into a control group and an experimental group, with 50 children in each group. The control group was randomly positioned. The experimental group adopted the medical electric multifunctional bed auxiliary body position to maintain the elevation of the head of the bed 15-20°, formulated the clinical nursing procedures, and implemented the comprehensive application of hierarchical nursing, bedside responsibility system, and humanized detail nursing. The improvement of pulse oxygen saturation, gastric motility promotion, and reduction of residual milk volume before meal were compared between these two groups.

96 children in the experimental group got improvement in pulse oxygen saturation (above 95%), and 82% in the control group (P=0.025). All the children (100%) in the experimental group had gastric motility promotion and residual milk volume less than 30% of total feeding milk, and 86% in the control group (P=0.006).

The implementation of body position management for preschool children in critical care unit raises the head of the bed by 15-20°, formulates clinical nursing procedures, and comprehensively applies hierarchical nursing, bedside work system, and humanized detailed nursing, which can improve pulse oxygen saturation, promote gastric motility, and reduce residual milk volume before meal.
