口服消炎痛和布洛芬治疗早产儿动脉导管未闭的比较

目的：静脉注射消炎痛是早产儿动脉导管未闭的常规治疗方法，但治疗过程中常出现一些副作用，如少尿、消化道出血、脑血流灌注减少。近年来，静脉注射布洛芬已用于治疗早产儿动脉导管未闭。布洛芬治疗不会减少脑血流灌注，也不会影响胃肠道和肾脏的血流动力学。伊朗目前尚无消炎痛和布洛芬的静脉制剂供应。该研究旨在比较这两种药的口服制剂治疗早产儿动脉导管未闭的疗效和安全性。方法：36例胎龄小于34周经超声心动图确诊患有动脉导管未闭的早产儿被随机分为两组，每组18人。一组给予消炎痛口服，每次0.2 mg/kg，24 h给药 1 次,共3次。另一组给予布洛芬口服，共 3 次，间隔时间为24 h，首剂为 10 mg/kg，随后两次各 5 mg/kg。用药后观察导管闭合率、副作用、并发症及临床过程。结果：用药后布洛芬组18例患儿动脉导管都闭合（100％），而消炎痛组18例中有15例患儿动脉导管闭合（83.3%）（P＞0.05）。两组疗效差异统计学无显著性意义。治疗前后两组的血清尿素氮和肌酐含量差异也无显著性意义。消炎痛组发生了3例（16.6%）坏死性小肠结肠炎，布洛芬组则无，差异有显著性意义 (P＜0.05)。治疗1个月后两组成活率均为 94%（17／18）。消炎痛组1例死于坏死性小肠结肠炎，布洛芬组1例死于败血症。结论：口服布洛芬治疗早产儿动脉导管未闭和口服消炎痛治疗一样有效，而且坏死性小肠结肠炎的发生率较口服消炎痛治疗低。［中国当代儿科杂志，2007，9（5）：399-403］

Comparison of oral ibuprofen and indomethacin therapy for patent ductus arteriosus in preterm infants

OBJECTIVE: Intravenous indomethacin is the conventional treatment for patent ductus arteriosus (PDA) in preterm infants; however its use is associated with various side effects such as oliguria, gastrointestinal bleeding and reduction of cerebral perfusion. Intravenous ibuprofen has recently been used to treat PDA in preterm infants without reducing cerebral blood flow or affecting intestinal or renal hemodynamics. Intravenous forms of indomethacin and ibuprofen are not available in Iran. This study aimed to examine and compare the efficacy and safety of oral ibuprofen and oral indomethacin for the treatment of PDA in preterm infants. METHODS: Thirty-six infants (gestational age less than 34 weeks) who had echocardiographically confirmed PDA were enrolled in this study. The patients were randomly administered with three oral doses of either indomethacin (0.2 mg/kg, at an interval of 24 hrs) or ibuprofen (a first dose of 10 mg/kg, followed at an interval of 24 hrs by two doses of 5 mg/kg each) (n=18 each group). The rate of ductal closure, side effects, complications, and the infants' clinical course were recorded. RESULTS: The ductus was closed in all of 18 patients (100%) in the ibuprofen group and in 15 (83.3%) patients in the indomethacin group (P > 0.05). There were no significant differences in the levels of serum blood urea nitrogen and creatinine between the two groups before and after treatment. Necrotizing enterocolitis (NEC) occurred in 3 patients in the indomethacin group and none in the ibuprofen group (P < 0.05). The survival rate at 1 month after treatment was 94% (17/18) in both groups. One infant in the ibuprofen group died from sepsis and one in the indomethacin group died as a result of NEC. CONCLUSIONS: Oral ibuprofen is as effective as oral indomethacin for the treatment of PDA in preterm infants. Oral ibuprofen therapy is associated with a lower incidence of NEC.
