ABSTRACT
Neonate is undergoing the transition from fetal circulation to adult circulation in the early period after birth, always accompanied by complex hemodynamic changes.Critical illness in neonates can cause a series of hemodynamic changes.In this article, the main parameters for evaluating neonatal hemodynamics, common methods for monitoring neonatal hemodynamics, and hemodynamic monitoring of common neonatal critical illness were described.
ABSTRACT
Objective@#To evaluate the consistency of ultrasonic cardiac output monitor (USCOM) and electric impedance (ICON) in cardiac function monitoring in preterm infants compared with echocardiography (ECHO).@*Methods@#All enrolled children were monitored with ECHO, USCOM and ICON on the 2nd and 7th day after birth.Heart rate (HR) and cardiac index (CI) were recorded.@*Results@#On the second day after birth, the CI measured by ECHO was (3.26±0.68) L/(min·m2), the CI measured by USCOM was (3.21±0.66) L/(min·m2), and the CI measured by ICON was (3.67 ±0.69) L/(min·m2), with an average percent error of 27.9% and 42.3%, respectively.On the 7th day after birth, the CI measured by ECHO was (3.53±0.57) L/(min·m2), the CI measured by USCOM was (3.47±0.59) L/(min·m2), and the CI measured by ICON was (3.73±0.67)L/(min·m2), with an average percent error of 25.8% and 28.3%, respectively.@*Conclusion@#Comparing USCOM with ECHO in cardiac output monitoring of preterm infants, the consistency is good at each time point after birth.Compared with ECHO, ICON has poor consistency in early postnatal cardiac index monitoring, but dynamic monitoring has a certain reference value after one week of birth.
ABSTRACT
Objective To investigate whether the therapy of combining budesonide with pulmonary surfactant,compared with only surfactant,has an effect on the incidence of bronchopulmonary dysplasia,mortality and other complications in preterm infants.Methods The preterm infants in accordance with the inclusion criteria,who were born during from 12/2016 and 2/2018,were randomly divided into the combination treatment group (treated with the combination of budesonide and pulmonary surfactant) and control group (treated with only surfactant).Ninety eight preterm infants were enrolled this trial,48 of whom are in budesonide group and 50 are in control group.The basic data were not have statistic significant between two groups except for birth weight (P ＞ 0.05).The incidence of bronchopulmonary dysplasia,the mortality and other complication of premature were compared.Results There was a statistic significance in the incidence of bronchopulmonary dysplasia between the budesonide group and control group (42％ vs 66％,P＜0.05);The severity of bronchopulmonary dysplasia and case fatality rate between two groups have no satistical difference.The complications of preterm infants in two groups also have no statistical difference apart from the incidence of PDA (15％ vs 38％,P ＜ 0.05).Conclusion Budesonide combined with pulmonary surfactant can reduce the incidence of bronchopulmonary dysplasia and does not increase mortality and the rate of other complications in preterm infants.
ABSTRACT
The development of neonatal intensive care unit (NICU) partly depends on modem medical eqnipment and technology.This paper will trace the latest monitor technology and biomedical engineering related treatment technologies in NICU,besides the bedside microbiochemical tests,ultrasound,radiology,brain function monitoring and retinal screening monitoring technology,as well as temperature control,circulation support,renal replacement therapy,provided biomedical related technical guidance for monitoring and treating the critical neonates.
ABSTRACT
Neonatal candida colonization is the most important risk factor of neonatal invasive candidiasis.Knowing the characteristics is conducive to recognize the candida colonization early and evaluate the risks of IC.The article reviews the incidence,time,place,trains,transmission,risks of neonatal candida colonization and the relation between candida colonization and IC in neonatal wards,providing the evidence for neonatal IC prophylaxis.
ABSTRACT
Objective To investigate the nursing cooperation in clinical application of RetCamⅢ wide-field digital pediatric retinal imaging system.Methods 119 patients were given pointed nursing guidance while they underwent RetCamⅢ wide-field digital pediatric retinal imaging system examination.Results All patients accomplished the examination.29 cases had adverse reactions after using mydriatic.27 cases felt discomfort during the examination.22 cases appeared adverse reactions after examination,but relieved after nursing cooperation and guidance.Conclusions RetCamⅢ wide-field digital pediatric retinal imaging system is a rapid,safe and effective method for pediatric fundus examination.Favorable nursing cooperation and guidance is the guarantee of accurate and effective examination and harmonious relationship between doctor-nurse-patient.
