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 了解惠州市早产儿视网膜病变的发病状况,并探讨相关危险因素。方法 回顾分析我院在2015年1月—2015年9月776例(1552只眼)早产儿和低体重儿的眼病筛查资料。结果 776例早产儿中,发现各期ROP共27例,检出率3.479%,其中包括1期11例(18只眼),2期11例(22只眼),3期2例(4只眼),AP-ROP3例(6只眼)。统计学分析显示,ROP组和无ROP组在出生胎龄、出生体重、吸氧史间比较,差异有统计学意义,提示早产、低出生体重与ROP的发生密切相关。结论 惠州地区ROP发病率3.479%,出生体重、出生胎龄、吸氧史及宫内缺氧、母体慢性高血压合并妊娠等孕期母体因素都是影响其发生的高危因素。

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.

目的 探讨光疗对早产儿血浆β-内啡肽含量的影响及与早产儿呼吸暂停的相关性。方法 收集我院住院早产儿92例,检测早产儿光疗前、中、后的血浆β-内啡肽及血清电解质、血糖及pH值,并将光疗过程中出现呼吸暂停者纳入光疗呼吸暂停组28例,无呼吸暂停者纳入光疗非呼吸暂停组44例,并设非光疗无呼吸暂停早产儿为对照组20例,比较组间上述指标的差异。结果 各组早产儿的血清电解质、血糖、血液pH值在光疗前、中、后无变化,差异无统计学意义(P>0.05)。光疗呼吸暂停组的血浆β-内啡肽浓度在光疗前、中、后无变化,差异无统计学意义(P>0.05),光疗呼吸暂停组和非呼吸暂停组之间血浆β-内啡肽的浓度无变化,差异无统计学意义(P>0.05),光疗组与非光疗组β-内啡肽浓度无变化,差异也无统计学意义(P>0.05)。结论 早产儿光疗前后β-内啡肽浓度无变化,呼吸暂停与β-内啡肽含量无相关性。
