β-海洋性贫血儿无通气期安全时限的研究

APNEA PERIOD SECUITY STUDY IN THALASSEMIA CHILDREN

目的:研究β海洋性贫血儿耐受缺氧的时间。方法:36例病儿分为两组,组为脾亢的β海洋性贫血儿,组为正常儿,用血氧饱和度监测仪监测SpO2发生的时间。结果:预吸氧前后SpO2两组无明显差异,降至最低时的SpO2组低于组,组的T1、T2、T3比组明显延长,但T95～90两组相比无差异。结论:β海洋性贫血儿无通气期的安全时限较短,麻醉诱导中预吸氧时间最好能达到3min。

Objective:To study the time of anoxia tolerance in thalassemia children Method:36 cases were divided into thalassemia with splenomegaly group(Ⅰ) and normal children(Ⅱ) The chang oarterial oxygen saturation(SpO 2) was monitored with pulse oxymeter Results:There was no significant difference of SpO 2 between both groups before preoxygenation;when SpO 2 decrease to the minimum value,group Ⅰ was lower than group Ⅱ,and T 1,T 2,T 3 in group Ⅱ was significantly prolonged compared with group Ⅰ,but there was no difference between both groups for T 95~90 .Conclusion:Apnea period security time is short in thalassemia children During anesthesia induction,preoxygenation is preferable to cast for 3 min
