目的探讨早产儿生后早期外周循环的变化,以指导早产儿救治。方法选择2013年9~12月山西省儿童医院新生儿科收治的早产儿,用MasimoRadical-7(USA)SpO2监测仪连续监测早产儿出生后一周内的灌注指数(PI),并进行比较。结果早产儿生后每天PI值呈现稳定上升趋势[1 d:(1.25±0.49),2 d:(1.33±0.45),3 d:(1.46±0.59),4 d:(1.51±0.56),5 d:(1.57±0.57),6 d:(1.74±0.70),7 d:(1.68±0.69)],生后第5、6、7天PI值高于第1天,第6天高于第2天,差异有统计学意义(P<0.05);其余各日龄间差异无统计学意义(P>0.05)。出生第5天后PI达到相对稳定。结论早产儿生后早期外周循环灌注水平相对较低,PI随日龄增长而增加并逐渐稳定。
Objective To investigate the changes of peripheral circulation in premature infants after prenatal infancy to guide the treatment of premature infants. Methods Preterm infants admitted to neonatology department of Children’s Hospital of Shanxi Province from September to December 2013 were selected. Perfusion index (PI) within one week after birth was monitored continuously by Masimo Radio-7 (USA) SpO2 monitor and compared. Results The PI value of preterm infants increased steadily (P <0.05), and the PI value of preterm infants increased steadily (P <0.01) The PI value on the 5th, 6th and 7th day after birth was higher than that on the 1st day, and on the 6th day, it was higher than that on the 6th day (P <0.01) 2 days, the difference was statistically significant (P <0.05); the rest of each age difference was not statistically significant (P> 0.05). After the 5th day of birth, the PI is relatively stable. Conclusions Peripheral blood perfusion is relatively low in preterm infants with preterm infants. PI increases with the increase of age and gradually stabilizes.
