早产儿呼吸暂停局部脑组织氧监测和处理

目的:探讨早产儿呼吸暂停时局部脑组织氧监测情况及相应处理方法。方法:应用TSAH-100型近红外组织血氧参数无损监测仪对329例早产儿在出生后的第1、2、3、5、7天的同一时间进行脑组织氧饱和度(regional cerebral oxygensaturation,rSO2)的监测,使用Agilent M1205A新生儿监护仪同步测定经皮脉搏氧饱和度(pulse oxygen turation,SO2)。结果:329例早产儿中监测到26例呼吸暂停时脑氧合出现下降,呼吸暂停时SO2与rSO2的变化有明显的相关性,且rSO2下降较SO2出现得更早,灵敏度更高。结论:早产儿呼吸暂停时rSO2的监测有利于临床上及时发现早产儿呼吸暂停并积极予以相应的治疗,加强呼吸道管理,对减轻脑缺氧损伤的发生有着重要的意义。

Detection and treatment of regional cerebral oxygen saturation in apnea of premature infant

Objective:To study the changes and treatment of region cerebral oxygen saturation(rSO2) in premature infant with apnea.Methods:TSAH-100 near infrared spectra photometry was used to detect the changes of rSO2 in 329 cases premature at the first day and 2、3、5、7 days after birth.At the same time,pulse oxygen situation(SO2) was also detected by Agilent M1205A pulse oximeter.Results:The changes of rSO2 were correlated with the SO2,the changes of rSO2 were earlier than SO2.Conclusion:The detection of rSO2 is more effective in apnea of premature infant.Near infrared spectra photometry is an effective method for the early diagnosis of apnea.It' benefit to decrease the leasions of the brain.
