【摘要】:目的:探讨血管迷走性晕厥(vasovagal syncope,VVS)患儿基于24h尿钠水平临床干预后尿钠及血流动力学参数的变化,评价口服补液盐及美托洛尔对低尿钠VVS患儿的临床疗效。方法:选取2014年6月至2016年3月在兰州大学第二医院儿童医院门诊就诊或住院的临床有反复晕厥或晕厥先兆表现(晕厥频次≥2次)的儿童,经详细询问病史、体格检查及辅助检查,排除发热、感染及器质性疾病所致晕厥,符合《儿童晕厥诊断指南》标准,征得患儿家属书面知情同意后,经直立倾斜试验(head-up tilt testing,HUTT)确诊为VVS的患儿共120例,根据所测24h尿钠选取124mmol/24h的患儿79例作为研究对象,按数据表法随机分为温开水组(n=15例)、口服补液盐组(n=21例)、美托洛尔组(n=21例)、口服补液盐与美托洛尔联合治疗组(n=22例)。比较低尿钠患儿干预3月后HUTT的结果,分析干预后各组24h尿钠、血清钠水平及血流动力学参数变化,评价不同干预方案临床疗效。相关数据均采用SPSS 19.0统计学软件进行数据处理、分析。结果:(1)口服补液盐组和联合治疗组治疗后24h尿钠水平与治疗前比较显著升高,联合治疗组尿钠升高幅度高于口服补液盐组(P0.05),治疗后血清钠水平均无明显变化(P0.05)。联合治疗组和美托洛尔组治疗后,直立倾斜即刻与基础心率的差值较治疗前缩小(P0.05)。(2)温开水组、口服补液盐组、美托洛尔组、联合治疗组治疗3月后的有效率分别为26.67%(4/15例)、66.67%(14/21例)、71.43%(15/21例)、95.45%(21/22例)。HUTT转阴率分别为6.67%(1/15例)、43.86%(9/21例)、52.38%(11/21例)、86.36%(19/22例)。联合治疗组治疗的有效率和HUTT转阴率优于其他三组,差异均有统计学意义(P0.05)。(3)VVS血管抑制型、心脏抑制型和混合型之间24h尿钠、血清钠血流动力学参数及各组疗效比较差异均无统计学意义(P0.05)。结论:低尿钠VVS患儿有明显血流动力学改变,临床干预后得到改善;口服补液盐与美托洛尔联合治疗的临床疗效及HUTT转阴率优于单一治疗,是VVS临床干预安全有效的方法;口服补液盐联合美托洛尔对VVS三种血流动力学反应类型疗效一致。
