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.

Objectives To discover the depression status and salivary cortisol(SC)level among women with threatened preterm labor, and find their associations. Methods 138 pregnant women with threatened preterm labor were recruited in this study. Edinburgh Postpartum Depression Scale (EPDS) was applied to assess women's depression, and their saliva were collected at 8am, 16pm,23pm to test the cortisol level. EPDS≥9.5 was set as the cut-off value to assign the participants to depressive group(EPDS≥9.5) and non-depressive group (EPDS＜9.5). Independent samples t-test was used to compare the difference of salivary cortisol of the two groups, and Pearson correlation analysis was also applied to calculated the associations between depression and salivary cortisol. Results The average scores of EPDS in total women were (8.8±4.97). The incidence of depression (EPDS≥9.5) was as high as 46.4%.The average level of salivary cortisol at 8am,16pm and 23pm were(14.07±7.36) ng/mL, (9.27±5.03)ng/mL and (5.71±3.92)ng/mL respectively. EPDS in total women was associated with 8amSC(r=0.257, P=0.002) and 16pmSC(r=0.303, P＜0.001). EPDS in non-depressive group were also associated with 8amSC (r=0.306,P=0.008) and 16pmSC(r=0.203, P=0.048). Conclusion Women with threatened preterm labor have a high incidence of depression. There was a low-moderate level of association between maternal depression and salivary cortisol. Obstetrical doctors and nurses should focus on maternal psychological health level in women with threatened preterm labor. Even those individuals comparatively with a less severe depression, we need help them to minimize the severity of depression to achieve satisfying pregnant outcomes.

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。

目的 探讨分析氨茶碱治疗早产儿呼吸暂停的临床疗效及其在治疗过程中所出现的不良事件。方法 选取2014年9—2016年3月广州市第一人民医院新生儿科接受住院治疗的胎龄＜34周,生后2 h内入住新生儿科的早产儿42例。随机分为对照组和氨茶碱组,对照组(20例)给予保暖、吸氧、补充能量、保持呼吸道通畅、物理刺激等对症治疗,不使用氨茶碱及其它改善呼吸的药物;氨茶碱组(22例)患儿除给予对照组治疗措施外,同时给予氨茶碱静脉滴注,首剂负荷量5 mg/kg,在20min内完成,12 h后以2～2.5 mg/kg维持量,每隔12 h一次。观察两组的疗效与不良影响。结果 ①两组患儿性别、出生胎龄、出生体重、产前孕母糖皮质激素的应用、受孕方式、分娩方式、多胎妊娠、5min Apgar评分、机械通气及CPAP辅助通气例数、低-中流量吸氧(箱内或头罩给氧)例数等方面差异均无统计学意义(P均＞0.05)。②与对照组相比,氨茶碱组早产儿呼吸暂停(AOP)发生的次数较少,AOP消失所需时间较短,差异均有统计学意义(P＜0.05)。③不良影响方面,氨茶碱组脑白质发育不良发生率(63.6%,14/22例)显著高于对照组(25%,5/20例),差异有统计学意义(P＜0.05);两组患儿在听力检查异常、喂养不耐受、血糖紊乱、血脂代谢紊乱、血红蛋白下降、电解质紊乱、出院时体重及住院时间等方面均无统计学意义(P均＞0.05)。④氨茶碱组视网膜发育不完全的发生率(40.9%,9/22例)明显高于对照组(15.0%,3/20例),但差异无统计学意义(P＞0.05)。结论 小剂量氨茶碱在防治AOP方面的作用是值得肯定的,但它有可能增加早产儿脑白质发育不良的风险与视网膜发育不完全的风险。

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.
