Percutaneous cannulation of the internal jugular vein in infants is technically more difficult and carries a higher risk of carotid artery puncture than in older children and adults. In this prospective study, the authors tested their hypothesis that using an ultrasound scanner would increase the success of internal jugular cannulation and decrease the incidence of carotid artery puncture in infants.
After approval from the institutional review board and receipt of written informed parental consent, 95 infants scheduled for cardiac surgery were randomized prospectively into two groups. In the landmarks group, the patients' internal jugular veins were cannulated using the traditional method of palpation of carotid pulsation and identification of other anatomic landmarks. In the ultrasound group, cannulation was guided using an ultrasound scanner image. The cannulation time, number of attempts, success rate, and incidence of complications were compared for the two groups.
There were no significant differences between the two groups with regard to weight, age, and American Society of Anesthesiologists physical status classification. The success rate was 100% in the ultrasound group, with no carotid artery punctures, and 77% in the landmarks group, with a 25% incidence of carotid artery punctures. Both differences were significant (P > 0.0004). The cannulation time was less, the number of attempts was fewer, and the failure rate was significantly lower in the ultrasound group than in the landmark group.
Ultrasonographic localization of the internal jugular vein was superior to the landmarks technique in terms of overall success, speed, and decreased incidence of carotid artery puncture.
与大龄儿童和成人相比,婴儿经皮颈内静脉置管在技术上更具难度,且颈动脉穿刺风险更高。在这项前瞻性研究中,作者检验了他们的假设,即使用超声扫描仪可提高婴儿颈内静脉置管的成功率,并降低颈动脉穿刺的发生率。
经机构审查委员会批准并获得家长书面知情同意后,将95例计划接受心脏手术的婴儿前瞻性随机分为两组。在体表标志组,采用传统的触诊颈动脉搏动及识别其他解剖标志的方法对患者进行颈内静脉置管。在超声组,使用超声扫描仪图像引导置管。比较两组的置管时间、穿刺次数、成功率及并发症发生率。
两组在体重、年龄及美国麻醉医师协会身体状况分级方面无显著差异。超声组成功率为100%,无颈动脉穿刺发生;体表标志组成功率为77%,颈动脉穿刺发生率为25%。两组差异均有统计学意义(P<0.0004)。超声组的置管时间更短,穿刺次数更少,失败率显著低于体表标志组。
在总体成功率、速度及降低颈动脉穿刺发生率方面,超声引导下颈内静脉定位优于体表标志技术。
