目的 探讨微量喂养对早产儿早期喂养不耐受喂养结局的影响。方法 选择我院2019年1月—2020年6月胎龄≤34周、出生后1周内反复出现喂养不耐受的早产儿78例,采用随机数字表法分为微量喂养组(38例)和中断喂养组(40例),比较两组患儿喂养不耐受的改善及喂养结局的差异性。结果 相对于直接中断喂养,微量喂养3～5天的患儿喂养不耐受改善率更高、体质量增长速度更快、更早达完全肠内喂养时间、静脉营养时间和住院时间也缩短了。而且胆汁淤积症发生率也低于中断喂养组,差异具有统计学意义,两组坏死性小肠结肠炎发生率比较无差异。结论 对于胎龄≤34周、生后1周内反复出现喂养不耐受的早产儿,在排除了外科或败血症早期表现的情况下,相对于中断喂养,选择微量喂养可改善患儿的喂养结局,而且不会增加坏死性小肠结肠炎的发生。

Objective To investigate the effect of minimal feeding on the outcome of early feeding intolerance in premature infants. Methods Seventy-eight premature infants with gestational age＜34 weeks and recurrent feeding intolerance within 1 week after birth in our hospital from January 2019 to June 2020 were selected. They were randomly divided into minimal feeding group (38 cases) and interrupted feeding group (40 cases) to compare the improvement of feeding intolerance and the difference of feeding outcome between the two groups. Results Compared with discontinuation of feeding, the rates of feeding intolerance improvement were higher in children who were given minimal feeding for 3-5 days,and they had faster weight gainand, the time to complete enteral feeding got earlier, intravenous nutrition time and hospitalization time were also shortened. Moreover, the incidence of cholestasis was also lower than that of the interrupted feeding group, and the difference was statistically significant. There was no difference in the incidence of necrotizing enterocolitis between the two groups. Conclusion For premature infants with gestational age＜34 weeks and feeding intolerance happened within 1 week after birth, excluding the early manifestation of surgery or sepsis, minimal feeding can improve the feeding outcome of the infants compared with discontinuation of feeding, without increasing the incidence of necrotizing enterocolitis.

Objective To analyze the physical development and parenteral nutrition status of preterm infant in a hospital in order to provide reference for the formulation of reasonable parenteral nutrition treatment plan for medium preterm infants. Methods The clinical data of 50 preterm infants aged 32～33⁺⁶ weeks from October 2017 to December 2018 were collected and analyzed retrospectively. Results The average birth weight, body length and head circumference of the child patients were (1.84±0.24) kg, (42.92 ±2.16) cm, (29.77±1.20) cm respectively. After one week and After two weeks,the average birth weight, body length and head circumference were(1.83±0.24) kg, (43.28±1.95) cm, (29.97±1.32) cm respectively and (2.07±0.23) kg, (43.91±1.79) cm, (30.62±1.13) cm respectively. The initial dose of amino acid(1.11±0.37)g·kg^-1·d^-1, fat emulsion(0.78±0.22)g·kg^-1·d^-1, glucose(5.86±1.51)mg·kg^-1·min^-1. The average days of parenteral nutrition treatment were(22.8±6.46)d, the average weight loss was(7.22±3.82)% and the average days of recovery to birth weight were (8.3±2.72)d. Conclusion The design of parenteral nutrition for preterm infants still needs to be improved in order to control the degree and duration of physiological weight loss of preterm infants in the mid-term, which is conducive to the physical development of preterm infants in the mid-term.

目的 探讨<34周早产儿发生晚发型败血症的危险因素及其病原分布,为防控及治疗用药提供依据。方法 选择2015年1月—2017年12月本院收治的<34周早产儿,根据是否发生晚发型败血症分为感染组及对照组,回顾性分析两组临床资料,对其可能的危险因素采用多因素Logistic回归分析。分析感染组患儿所感染的病原菌及其药敏情况。结果 感染组27例,对照组73例,单因素分析显示感染组患儿出生体重低于对照组,出生窒息、机械通气、使用H₂受体阻滞剂、多种抗生素使用、经外周中心静脉置管（PICC）及PICC留置≥14天比例均高于对照组,差异有统计学意义（P<0.05）。多因素logistic回归分析显示出生体质量、PICC留置是<34周早产儿发生晚发型败血症的独立危险因素。感染组中血培养阳性20例,真菌培养阳性11例（55.0%）,G⁺菌5例（25.0%）,G^-菌4例（20.0%）。药敏结果中两性霉素B和氟康唑敏感性高。结论 早期早产儿发生晚发型败血症受多重因素影响,真菌已成为主要致病菌,应针对高危因素加强感染防控,根据血培养及药敏结果合理使用抗菌药物。

早期干预是预防和减少早产儿神经系统损伤的有效措施,可以促进早产儿的正常发育并减轻神经系统伤残的发生,对提高儿童综合素质和家庭幸福都至关重要。在早产儿早期干预过程中存在与医学伦理原则不相适应的方面,如医疗设施不足、医疗措施不当、专业人员不足,早产儿干预预后的不确定性,治疗时机与家长经济及遵医行为之间的冲突,家长知情选择和知情同意不足等,本文结合医学伦理学的观点对0~3岁早产儿在早期干预中存在的问题进行分析并提出相应的建议。

Early intervention is an effective measure to prevent and reduce the nervous system injury in preterm infants,It can promote the normal development of preterm infants and reduce the occurrence of the nervous system disability.It is vital to improve the comprehensive quality of children and family quality of life. In the stage of premature infant intervention,there are some aspects that are incompatible with the medical ethics principle,i.e. inadequate medical facilities,improper medical measures,lack of professionals,premature infants intervention prognosis uncertainty,the conflict between the timing of treatment and the parents' economic and compliance behaviors,parents' informed choice and informed consent. etc. This paper analyzes the problems in early intervention of 0~3 year old preterm infants and puts forward corresponding suggestions according to the viewpoint of medical ethics.

Objective To investigate the clinical efficacy and adverse effects of aminophylline in prevention of apnea of prematurity. Methods Forty-two infants with gestational age ＜34 weeks admitted to department of pediatrics, Guangzhou first people's hospital between Sep. 2014 and Mar. 2016 were randomly divided into 2 groups: control group and aminophylline group. Control group(n=20): 20 infants received warming, oxygen inhalation, supplement energy, maintain airway patency, physical stimulation, such as symptomatic treatment, without aminophylline or any other drugs for improving breathing. Aminophylline group(n=22): In addition to the control group treatment measures, 22 infants received a loading dose of 5 mg/kg of aminophylline and then maintained by a dose of 2mg/kg with intravenous drip q 12 h. Then we compared the efficacy and adverse effects of the two groups. Results ①There was no significant difference in gender, gestational age, birth weight, maternal antenatal glucocorticoid application, pregnancy(including multiple pregnancy) and delivery,5 min Apgar score, oxygen therapy, the application of mechanical ventilation, nasal continuous positive airway pressure, and the low-medium flow oxygen inhalation between the 2 groups(all P＞0.05). ② Compared with the control group, the incidence of apnea in aminophylline group were significant lower, and the time needed for apnea to disappear were significant shorter(all P＞0.05). ③ The incidence of cerebral white matter development dysplasia of aminophylline group(63.6%,14/22 cases) were significant higher than the control group(25%,5/20 cases, P＜0.05). There was no statistically significant difference in hearing loss, feeding intolerance, blood glucose disturbance, blood lipid metabolism disorder, hemoglobin decrease, electrolyte disorder, body weight at discharge, the duration and cost of hospitalization between the 2 groups(all P＞0.05). ④ The incidence of retinal incompleted development of aminophylline group(40.9%, 9/22 cases) were higher than control group(15.0%, 3/20 cases), but there was no statistical significance between the 2 groups(P＞0.05). Conclusion Effects of aminophylline in treating apnea of prematurity is positive, but it is likely to increase the risk of premature brain white matter development dysplasia and the risk of retinal incompleted development.

Objective To study the incidence of retinopathy of prematurity and to analyse the risk factors for ROP. Methods A retrospective analysis was conducted on 776 premature children from January 2015 to September 2015. Results In the 776 premature babies examinaion, 26 cases(54 eyes, 3.479%)developed ROP, including 11 cases (18 eyes) suffering from stage 1,11 cases (22 eyes) from stage 2,2 cases (4 eyes) from stage 3,3cases (6 eyes) from AP-ROP. The results of statistical analysis showed that gestational age, birth weight and oxygen therapy were significantly to ROP. Clinical analysis indicated that prematurity, low birth weight and oxygen therapy were closely related to the occurrence of ROP. Conclusion The incidence of ROP in Huizhou city is 3.479%. The gestational age, birth weight ,intrauterine hypoxia, and maternal prenatal factors such as chronic hypertension with pregnancy are the high risk factors of ROP.
