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.

目的 了解CHPS患儿经胃镜下幽门肌切开术治疗后幽门部黏膜近期各种并发症的发生情况及对预后的影响。方法 选取2006—2012年我院新生儿科确诊的34例CHPS患儿。以超细胃镜进入十二指肠乳头处,使用电切刀按上行性方向,沿幽门管纵轴切割肥厚狭窄的幽门管黏膜及环形肌以解除幽门部梗阻。术后第1、3、6月复查胃镜。结果 34例CHPS患儿共行胃镜下幽门肌切开术48次,均未发生胃及幽门穿孔、撕裂等严重并发症。24例患儿术后通过胃镜进行了复查,胃镜见幽门部及黏膜改变主要有黏膜充血肿胀、切口未完全愈合、切口疤痕形成、幽门部息肉形成等。结论 经胃镜下幽门肌切开术是一种安全性较高的治疗CHPS的新技术。术后黏膜充血肿胀、切口未完全愈合等幽门部黏膜改变的发生率随时间下降。切口疤痕形成并未影响幽门功能。

目的 探讨新生儿早发型B族链球菌(GBS)败血症的临床特点,提高对本病的认识。方法 选取我院2010—2012年我院新生儿重症监护病房(NICU)收治的新生儿资料,回顾性分析GBS的临床表现、实验室检查、治疗和转归。结果 早发型GBS败血症8例,占住院患儿的6.28‰,均为足月儿,生后24小时内发病,以气促、发绀等呼吸系统症状为主,其中4例出现感染性休克表现;实验室检查提示血常规WBC:2.07~14.1×10⁹/L,＜5×10⁹/L 5例,中性粒细胞绝对值0.54~8.32×10⁹/L。胸部X线提示:肺部纹理粗乱,渗出增多。1例需机械通气辅助呼吸。青霉素联合头孢三代或万古霉素治疗有效,重症感染者需加强支持治疗。结论 应重视新生儿早发型无乳链球菌败血症早期呼吸系统症状,尽早诊断和治疗,降低病死率。

Objective To investigate the clinical features of early-on set neonatal Group B Streptococcal (GBS)septicemia in order to guide the clinical diagnosis and treatment. Methods Retrospectively analysing the clinical presentation, laboratory examination, treatment and prognosis of the 8 cases of all newborns from 2010 to 2012 in our hospital. Results The incidence of neonatal early-on set Group B Streptococcal septicemia was 6.28‰.8 cases were full-term infants in this study.Respiratory symptoms such as anhelation and cyanosis were first signs of early-on set Group B streptococcal septicemia within 24 hours after birth; 4 cases of septic shock. Results of laboratory tests included WBC:2.07~14.1×10⁹/L, in which 5 cases were ＜5×10⁹/L, N 0.54~8.32×10⁹/L. Chest X-ray: lung texture showed coarse and disorderly, leakage was increased. One case needed respiratory support with mechanical ventilation. Intravenous treatment of neonatal GBS with penicillin combined with Vancomycin was effective. Patients of serve infections should be provided supportive care. Conclusion Patients of serve early symptom of respiratory system should be paid attention. Early diagnosis and treatment should be as soon as possible to reduce fatalities.
