重症肺炎患儿穴位组织氧监测的临床观察

目的]监测重症肺炎患儿足三里穴位组织氧变化,评估其局部组织氧合状态,探讨穴位组织氧测定法在临床中的应用价值。方法]24例重症肺炎患儿和22例轻症肺炎患儿进行对照。利用国产二通道组织氧测定仪,测定吸氧浓度(FiO2)40%时右下肢足三里穴位组织氧分压(PtO2),同时检测动脉血气、体温、心率、血压、血红蛋白,计算PtO2指数。结果]与轻症肺炎患儿组比较,重症肺炎患儿组体温、心率显著增高,PaO2显著降低;同时重症肺炎患儿组穴位组织PtO2指数、PtO2显著升高(P0.05)。结论]重症肺炎患儿在全身氧输送障碍的情况下,穴位局部组织的氧需求显著增加;穴位组织可能通过显著提高PtO2指数,来满足自身异常增高的氧需求。用穴位组织氧测定法监测重症肺炎患儿局部组织氧合状况,有十分显著的意义。

Clinical observation of monitoring of tissue oxygen in acupoints in infants suffering from serious pneumonia

Objective] By monitoring the changes of tissue Oxygen in ZuSanLi Point in infants suffering from serious pneumonia to evaluate the situation of its partial tissue Oxygenation and explore the applying value of measuring acupoint tissue Oxygen method clinically.Methods] The changes in twenty-four infants suffering from serious pneumonia were compared with that in infants from common pneumonia.Using dual-channels tissue Oxygen monitor made in China the pressure of tissue Oxygen(PtO₂) of ZuSanLi point of right leg was measured,at inhalational oxygen of 40%(FiO₂) Simultaneously,the arterial blood gas,temperature of body,heart rate,blood pressure and hemoglobin were measured to calculate the PtO₂ index(PtO₂/PaO₂).Results] Compared with the infants suffering from common pneumonia,the temperature and heart rate were significantly higher,PaO₂ was significantly lower,meanwhile the PtO₂ index and PtO₂ of point in infants with serious pneumonia were significantly increased.(P<0.05).Conclusion] Under the condition of oxygen delivery disorder of whole body in infants with serious pneumonia the need of partial tissue around point was significantly enhanced.The point tissue can significantly increase the PtO₂ index to meet the abnormally enhanced oxygen need of it self.Measuring the oxygen in acupoint tissue was very valuable to monitor the situation of partial tissue oxygenation in infants suffering from serious pneumonia.
