作者对8例心搏骤停后心肺复苏(CPR)中动静脉血气进行检查结果:动静脉血pH、PaO_2、BE、HCO_3~-均明显降低,而PaCO_2均明显升高。表明动静脉血均呈现混合性酸中毒及严重低氧血症。根据作者观察CPR期间动、静脉血均呈严重代谢性酸中毒,认为在复苏期间增大人工通气量的同时应进行补碱,但补碱量应慎重,首剂补充1mmol/kg,以后根据血气及pH决定用量。指出胸外按压5分钟,心脏无反应时应尽快开胸作胸内按压,以提高复苏的成功率。
The authors examined 8 arterial and venous blood gases after cardiac arrest (CPR) after cardioversion: arterial venous blood pH, PaO 2, BE, HCO 3 - - were significantly lower, while PaCO 2 were significantly higher. That arteriovenous blood showed mixed acidosis and severe hypoxemia. According to the authors observed during the CPR, arterial and venous blood were severely metabolic acidosis, that during the recovery of artificial ventilation should be carried out while increasing alkali, but make up the amount of alkali should be careful, the first dose of 1mmol / kg, after the blood gas And pH to determine the amount. Pointed out that chest compression for 5 minutes, the heart should be open chest for thoracic pressure without response, in order to improve the success rate of recovery.
