目的探讨婴幼儿重症肺炎血气分析及电解质变化及临床意义。方法对46例重症肺炎患儿资料进行回顾性分析,了解酸碱及电解质紊乱发生情况。结果重症肺炎患儿p H<7.35共30例,占65%;氧分压(PO2)<60 mm Hg(1 mm Hg=0.133 k Pa)37例,占80%;低钠血症(Na+<135 mmol/L)22例,占48%;高钾血症(K+>5.5 mmol/L)7例,占15%;低钙血症5例,占11%。46例患儿治愈32例、好转11例,未愈2例,死亡1例。结论重症肺炎出现低氧血症、酸中毒、低钠血症的比例高,宜采取综合治疗。
Objective To investigate the infantile severe pneumonia, blood gas analysis and electrolyte changes and clinical significance. Methods The data of 46 cases of severe pneumonia were retrospectively analyzed to understand the occurrence of acid-base and electrolyte imbalance. Results Thirty cases (65%) had p H <7.35 in severe pneumonia, 37 cases (80%) had hypoxemia (PO2) <60 mm Hg (1 mm Hg 0.133 kPa) 135 cases in group A and group B in 22 cases, accounting for 48%; 7 cases of hyperkalemia (K +> 5.5 mmol / L), accounting for 15%; 5 cases of hypocalcemia, accounting for 11%. Forty-six cases were cured in 32 cases, improved in 11 cases, unhealed in 2 cases, and died in 1 case. Conclusion Severe pneumonia appears hypoxemia, acidosis, hyponatremia, a high proportion, it is appropriate to take a comprehensive treatment.
