极低出生体质量儿闪光视觉诱发电位检测的临床意义

Objective To study the clinical significance of flash visual evoked potential(FVEP)detection in very low birth weight infants.Methods FVEP was performed in group of 43 very low birth weight infants with Medelecsynergy evoked potential instrument(Oxford Company,UK) comparing with the group of 56 term infants.Results The mean latency periods of N1,P1 and N2 waves in very low birth weight infant group were(181.43±26.73) ms,(217.27±26.54) ms,(249.21±26.49) ms respectively,while in term infant group were(159.51±18.27) ms,(200.26±13.94) ms,(231.56±15.72) ms.There were significant differences between two groups(P＜0.05,P＜0,001).The abnormal rates of main wave P1 were 75.6% and 0 respectively in very low birth weight infant group and term infant group.Furthermore,the major effect model for related influencing factors in very low birth weight infants with abnormal main wave was 3.898-2.861 intracranial lesion.Intracranial lesion was the independent risk factor for abnormal FVEP (0R=0.057,95% CI 0.006～0.579,P=0.015).Conclusion The abnormal rate of FVEP is higher in the very low birth weight infants,which is closely related to the intraeranial lesion.It is recomraended that FVEP is detected at least twice in the first month after birth or achieving the corrected gestational age of 42 weeks for dynamic observation.

前白蛋白在早产低出生体质量儿肠道外营养治疗中的意义

Objective To study the role of serum prealbumin in nutritional treatment of low birth weight premature infants of parenteral nutrition.Methods A total of 61 eases of low birth weight premature infants were divided into two groups: partial parenteral nutrition group(PPN group) and total parenteral nutrition group (TPN group). We detected the levels of serum prealbumin and albumin at the age of 20 hours and 7 days after birth of all infants respectively, at the same time,we observed the infants with body weight change and total caloric intake. Results Before the application of parenteral nutrition,the serum levels of prealbumin were(88.0 ± 9.1)mg/l in PPN group and (87.0± 8.7)mg/l in TPN group, and there were no significant difference between two groups(P > 0.05). Prealbumin levels of PPN group at the 7th day after birth were significantly higher than those of TPN group, which were (128.0 ± 10.8)mg/l in PPN group and (106.0 ± 10.9)mg/l in TPN group(t = 2.67, P < 0.05), and the serum levels of albumin between two groups were not significantly different.The body weight of PPN group was (1832 ± 185)g,close to or regain birth weight,and the body weight of TPN group was significantly lower than birth weight (t = 8.27, P < 0.01).The caloric intake of PPN group was significantly higher than that of TPN group (t = 2.81, P < 0.05) . Conclusion Prealbumin can better reflect the recent nutritional level than the albumin,and can act as the sensitive indicator for monitoring nutritional status of protein.
