ABSTRACT
Objective To investigate the effects of caffeine on cerebral cortical activity in preterm infants. Methods The preterm infants with 28-34 week gestational age and without asphyxia at birth were recruited as the subjects from January to September 2016. The infants who received conventional caffeine citrate were assigned to the caffeine group, while the infants with the same postmenstrual age did not receive any drugs that excite respiratory center were assigned to the control group. In the caffeine group, after the use of caffeine citrate stopped, the amplitude integration electroencephalogram (aEEG) recording were performed at 33, 34, 35 weeks of postmenstrual age. All the aEEG recordings were continuously monitored for at least 4 hours. The aEEG images were assessed by Burdjalov scoring system, and the interburst intervals were calculated. The effects of caffeine on preterm infants' cerebral cortical activity in early life were analyzed. Results In a total of 49 preterm infants recruited, 21 were in caffeine group and 28 in control group, and the ratio of male and female was 1.45:1. At the same postmenstrual age, the total score and individual scores of aEEG assessed by Burdjalov scoring system were not significantly different between caffeine group and control group. However, the length of interburst interval was significantly shorter in caffeine group than that in control group (P<0.05). All the recruited preterm infants had no seizure-like activity when the aEEG was monitored. Conclusion The use of caffeine citrate has effects on EEG activity in early life of preterm infants, which may accelerate the brain maturation of preterm infants
ABSTRACT
Objective In recent years,amplitude-integrated electroencephalography (aEEG)has been widely used in cerebral function monitor in NICU.It is a simplified form of electroencephalogram.Many study on term infants have shown that aEEG can help identify brain injury and predict nurodevelopment outcome.However,the aEEG in preterm infants relates to gestational age and can be influenced by many factors.Its prognostic value of neurodevelopmental impairment in preterm infants is still unclear and need to be determined.
ABSTRACT
@#ObjectiveTo explore the protective methods to the patients with insensitive feet caused by leprosy.Methods295 patients affected by leprosy (PAL) with insensitive feet did self-care and wore protective shoes which were bought in general market and met the requireing of with soft and elastic insole,hard sole higher instep, et al.All the patients had been followed up for 3 years.ResultsAll cases persisted on wearing those shoes, only 1 case occured fresh ulcer and no ulcers relapsed.Cracks and ulcers on foot declined by 96.15% and 32.81% respectively, and bone loss had no change.ConclusionsThe protective foot-wears can prevent the fresh ulcers happening and the healed ulcers reappearing for PALs with numb feet. It is important to educate the PALs how to choose the kind of foot-wears and how to do self-care.
