目的 探讨不同剂量西甲硅油对儿童胃镜操作的影响.方法 以重庆医科大学附属儿童医院预约行胃镜检查的≥2岁儿童作为研究对象.采用随机数字表法对2022-03-01-2022-12-31预约行胃镜检查的患儿随机分4组:A组口服20 mL温水作为对照,B组口服40 mg西甲硅油,C组口服100 mg西甲硅油,D组口服200 mg西甲硅油.比较4组有效性指标(胃镜视野清晰度情况、胃镜操作时间、镜下冲洗例数)及安全性指标(氧饱和度下降例数).结果 共纳入患儿800例,每组200例,各组性别构成和年龄分布差异无统计学意义(x2=0.981、H=2.239,均P＞0.05).视野清晰度良好率:A组、B组、C组和D组分别为38.5％、66％、80.5％和78.5％,A组低于B组、C组及D 组(x2AB=30.331、x2AC=73.203、x2 AD=65.905,均 P＜0.05);B 组低于 C 组和 D 组(x2 BC=10.730、x2BD=7.793,均P＜0.05);C组与D组差异无统计学意义(P＞0.05).胃镜操作时间:B组(192.0±53.6)s、C组(169.0±45.8)s及D组(169.8± 46.6)s显著短于 A 组(221.2±58.8)s(Z AB=-4.412、Z AC=-8.373、ZAD=-8.023,均 P＜0.05);C 组和 D 组短于 B 组(Z BC=-4.5、ZBD=-4.418,均P＜0.05);C组与D组差异无统计学意义(P＞0.05).镜下冲洗例数:A组(76例)显著高于B组(24 例)、C 组(10 例)及 D 组(11 例,x2 AB=36.053、x2 AC=63.394、x2AD=62.062,均 P＜0.05);B 组高于 C 组和 D 组(x2BC＝6.076、x2BD=5.292,均P＜0.05);C组与D组差异无统计学意义(P＞0.05).氧饱和度下降例数:4组比较差异无统计学意义(P＞0.05).结论 儿童胃镜检查前口服西甲硅油可显著提升胃镜视野清晰度,100mg西甲硅油即可达到理想的清洁效果.
Objective To compare the efficacy of different doses of simethicone on operation of upper endoscopy for children.Methods Patients aged ≥2 years old who received upper endoscopy in Children's Hospital of Chongqing Medical University from Mar.1 to Dec.31 of 2022 were included in this study.Study subjects were randomly assigned to 4 groups.Group A received 20 mL water before examination as control,Group B received 40 mg simethicone,Group C received 100 mg simethicone,and Group D received 200 mg simethicone.Visibility of upper endoscopy,procedure time,cases requiring endoscopic flushing,and cases of oxygen desaturation were compared and analyzed.Results A total of 800 pediatric patients were included in this study,200 patients in each group.There were no significant differences regarding gender composition and mean age in each group(x2=0.981,H=2.239,P＞0.05).The proportion of adequate visibility in Group A,Group B,Group C and Group D was 38.5％、66％、80.5％and 78.5％,respectively.The proportion of adequate visibility in group A was significantly lower than that in the other groups(x2AB=30.331,x2AC=73.203,x2AD=65.905,all P＜0.05).The proportion of adequate visibility in Group B was significantly lower than that in Group C and Group D(x2BC=10.730,x2BD=7.793,all P＜0.05).No significant differences were detected regarding proportion of adequate visibility between Group C and Group D(P＞0.05).Procedure time in group B[(192.0± 53.6)s],group C[(169.0±45.8)s],and group D[(169.8±46.6)s]was significant shorter than that in group A[(221.2±58.8)](ZAB=-4.412,ZAC=-8.373,ZAD=-8.023,all P＜0.05).Procedure time in Group C and Group D was significant shorter than that in Group B(ZBC=-4.5,ZBD=-4.418,all P＜0.05).No significant differences were detected regarding procedure time between Group C and Group D(P＞0.05).Cases requiring endoscopic flushing in Group A(76 cases)were significantly higher than those in Group B(24 cases),Group C(10 cases),and Group D(11 cases)(x2 AB=36.053,x2AC=63.394,x2AD=62.062,all P＜0.05).Cases requiring endoscopic flushing in Group B were significantly higher than those in Group C and Group D(x2BC=6.076,x2BD=5.292,all P＜0.05).No significant differences were detected regarding cases requiring endoscopic flushing between Group C and Group D(P＞0.05).There were no significant differences regarding cases of oxygen desaturation among the 4 groups(P＞0.05).Conclusion Premedication of simethicone can significantly improve the visibility during upper endoscopy in children,and 100 mg simethicone is enough to achieve an ideal cleaning effect.
