Investigation of effect by laryngeal mask general anesthesia controlled ventilation in pediatric painless fiber bronchoscope examination

目的对喉罩全身麻醉(全麻)控制通气在小儿无痛纤维支气管镜检查中的作用效果进行探讨。方法 68例接受纤维支气管镜检查的患儿,采取随机数字法分为研究组及对照组,各34例。研究组采取喉罩全麻控制通气;对照组实施常规静脉全麻。比较两组患儿纤维支气管镜检查前、中、后心率、平均动脉压及血氧饱和度的情况,并比较两组患儿不良反应发生率。结果研究组检查中心率、平均动脉压及血氧饱和度与检查前、后比较差异无统计学意义(P>0.05);对照组检查中心率、平均动脉压明显高于检查前、后,血氧饱和度低于检查前、后,差异具有统计学意义(P<0.05);且两组患儿检查中心率、平均动脉压、血氧饱和度比较差异具有统计学意义(P<0.05)。研究组不良反应率为5.88%,低于对照组的23.53%,差异具有统计学意义(P<0.05)。结论喉罩全麻控制通气在小儿无痛纤维支气管镜检查中的麻醉效果较优,且安全性较高,不良反应较少,值得推广。

Objective To investigate effect by laryngeal mask general anesthesia controlled ventilation in pediatric painless fiber bronchoscope examination. Methods A total of 68 children patients receiving fiber bronchoscope examination were divided by random number table into research group and control group, with 34 eases in each group. The research group received laryngeal mask general anesthesia controlled ventilation, and the control group received conventional intravenous general anesthesia. Comparison was made on heart rate, mean arterial pressure and oxyhemoglobin saturation before, under and after examination, and incidence of adverse reactions between the two groups. Results The research group had no statistically significant difference of heart rate, mean arterial pressure and oxyhemoglobin saturation under examination, comparing with those before and after treatment （P〉0.05）. The control group had higher heart rate, mean arterial pressure and lower oxyhemoglobin saturation under examination than those before and after treatment, and their difference had.statistical significance （P〈0.05）.The difference of heart rate, mean arterial pressure and oxyhemoglobin saturation under examination between the two groups had statistical significance （P〈O.05）. The research group had lower incidence of adverse reactions as 5.88% than 23.53% in the control group, and their difference had statistical significance （P〈0.05）. Conclusion Laryngeal mask general anesthesia controlled ventilation shows excellent anesthetic effect in pediatric painless fiber bronchoscope examination, along with high safety and few adverse reactions. This method is worth promoting.
