不同麻醉方法用于尿道下裂成形术患儿的效果

目的：评价不同麻醉方法用于尿道下裂患儿的效果。方法：择期拟行尿道下裂成形术患儿90例，ASA分级 为I或II级，年龄为2.0~6.0 (4.0±1.3)岁，体质量11.50~21.00 kg，采用随机数字表法，将患儿随机分为全身麻醉复合硬膜 外阻滞组(I组)、全身麻醉组(II组)和全麻喉罩复合硬膜外阻滞组(III组)，每组30例。所有患儿入室后静脉麻醉诱导， 麻醉维持均采用七氟醚吸入，使脑电双频指数值维持45~60。I组行硬膜外穿刺麻醉；II组麻醉诱导后置入喉罩；III组 置入喉罩并行硬膜外穿刺阻滞。观察3组的麻醉效果、血流动力学变化、不良反应和术后并发症。结果：与I组及II组 相比，III组患儿血压、心率更平稳，术后躁动和不良事件发生率均较两组低(均P<0.05)。结论：全麻喉罩复合硬膜外 阻滞用于尿道下裂的患儿麻醉效果优。

Efficacy of different methods of anesthesia on children underwent hypospadias surgery

Objective: To assess the efficacy of different methods of anesthesia on children underwent hypospadias surgery. Methods: A total of 90 children (2–6 years old, 11.5–21.0 kg weight) with I or II grade of hypospadias based on ASA standard, who scheduled for hypospadias angioplasty, were randomly divided into 3 groups: Group I, general anesthesia combined epidural anesthesia; Group II, laryngeal mask airway under general anesthesia; Group III, laryngeal mask airway under general anesthesia combined epidural block. All children were inhaled sevoflurane to keep bispectral index value in a range from 45 and 60. Th e Group I adopted epidural anesthesia aft er intravenous induction of anesthesia; the Group II was inserted laryngeal mask aft er induction; the Group III was inserted laryngeal mask after induction and adopted epidural block. The anesthesia efficacy, hemodynamic changes, adverse reaction and the postoperative complications were observed in the 3 groups. Results: Compared with the Group I or the Group II, the blood pressure and heart rate ran more smoothly in the Group III, and the postoperative agitation and incidence of adverse events were also significantly reduced (all P<0.05). Conclusion: The laryngeal mask airway under general anesthesia combined epidural block is a better choice for children scheduled for hypospadias angioplasty.
