To develop evidence-based recommendations for prevention and management of infections, bleeding, and local anesthetic toxicity in children undergoing regional anesthesia.
A joint committee of the European Society of Regional Anesthesia and Pain Therapy (ESRA) and the American Society of Regional Anesthesia and Pain Medicine (ASRA) studied electronic literature databases of pediatric regional anesthesia to construct evidence-based recommendations.
For epidural anesthesia lumbar or thoracic placement is preferred. Skin preparation prior to block placement with chlorhexidine is preferred to povidone iodine. A tunneled catheter technique is suggested when using the caudal route or if the epidural catheter placement is kept in situ for more than 3 days. Inspection of the epidural catheter insertion site should be performed at least once a day as part of the postoperative management. When medical and physical examination is normal, coagulation tests are usually unnecessary but if coagulation tests are abnormal, neuraxial and deep peripheral nerve blocks are contraindicated. For patients receiving Low Molecular Weight Heparin thromboprophylaxis, a safety interval of two half-lives plus the time required for heparin to reach maximal levels is considered an adequate compromise between bleeding risk and thrombosis risk when removing epidural catheters. Ultrasound-guided peripheral nerve blocks reduce the risk of vascular puncture and thus the risk of local anesthetic toxicity is reduced.
In children undergoing regional anesthesia the incidence of infection, hematoma, and local anesthetic toxicity is low. The ASRA/ESRA joint committee proposes a practice advisory to prevent and treat these complications.
为预防和管理行区域麻醉的儿童的感染、出血和局部麻醉中毒,制定循证推荐意见。
欧洲区域麻醉和疼痛治疗学会(ESRA)和美国区域麻醉和疼痛医学学会(ASRA)的一个联合委员会研究了小儿区域麻醉的电子文献数据库,以构建循证推荐意见。
对于硬膜外麻醉,腰椎或胸椎置管更优。与聚维酮碘相比,氯己定用于阻滞前皮肤准备更优。当使用骶管途径或硬膜外导管放置超过 3 天时,建议使用带隧道的导管技术。应至少每天检查一次硬膜外导管插入部位,作为术后管理的一部分。当医学和体格检查正常时,通常不需要凝血试验,但如果凝血试验异常,则禁止进行神经轴和深部外周神经阻滞。对于接受低分子肝素血栓预防的患者,在取出硬膜外导管时,两个半衰期加肝素达到最大水平所需的时间的安全间隔被认为是出血风险和血栓风险之间的一个足够的折衷。超声引导下的外周神经阻滞可降低血管穿刺的风险,从而降低局部麻醉中毒的风险。
在接受区域麻醉的儿童中,感染、血肿和局部麻醉中毒的发生率较低。ASRA/ESRA 联合委员会提出了一项实践咨询,以预防和治疗这些并发症。
