To establish whether a treatment regimen of silver nitrate cautery and 4 weeks of antiseptic nasal cream is superior to antiseptic cream treatment alone in the management of pediatric epistaxis.
Double-blind randomized controlled trial.
Children with epistaxis and visible anterior septal vessels were invited to participate. Patients were randomized to receive treatment or control. Treatment patients received silver nitrate cautery, followed by antiseptic cream for 4 weeks. Control patients received sham cautery followed by antiseptic cream for 4 weeks.
A total of 109 patients were randomized and results were available for 93 (85%). Of those receiving cautery, 21 (45.7%) of 46 had no bleeding in the 4 weeks before follow-up. Of those receiving only antiseptic cream 14 (29.8%) of 47 had no bleeding. (chi(2) = 2.49; P = 0.114). More children in the active treatment group had an improvement in their symptoms compared with controls (42 of 46; 91.3%) in the treatment group vs 33 of 47 (70.2%) controls (chi(2) = 6.626; P = 0.01; relative risk reduction = 71 percent, number needed to treat = 4.7).
When using subjective improvement in symptoms as the outcome measure, silver nitrate cautery with antiseptic cream twice daily for 4 weeks appears to give a small but statistically significant benefit when compared to antiseptic cream alone.
确定硝酸银烧灼联合4周抗菌鼻用乳膏治疗方案在小儿鼻出血治疗中是否优于单纯抗菌乳膏治疗。
双盲随机对照试验。
邀请有鼻出血且鼻中隔前部血管可见的儿童参与。患者被随机分为治疗组或对照组。治疗组患者接受硝酸银烧灼,随后使用抗菌乳膏4周。对照组患者接受假烧灼,随后使用抗菌乳膏4周。
共有109例患者被随机分组,93例(85%)有结果。在接受烧灼的患者中,46例中有21例(45.7%)在随访前4周无出血。在仅接受抗菌乳膏治疗的患者中,47例中有14例(29.8%)无出血。(卡方检验=2.49;P=0.114)。与对照组相比,积极治疗组更多儿童的症状有改善(治疗组46例中有42例;91.3%),而对照组47例中有33例(70.2%)(卡方检验=6.626;P=0.01;相对危险度降低=71%,需治疗人数=4.7)。
以症状的主观改善作为结局指标时,与单纯使用抗菌乳膏相比,硝酸银烧灼联合每日两次抗菌乳膏治疗4周似乎有小但具有统计学意义的益处。
