血气监护提高了我们对休克时存在各类酸碱紊乱的认识。本文抽取近五年的34例休克病例进行分析。代谢性酸中毒是休克中酸碱紊乱的主要类型(9例),及时适量地投用碱性药物是一项重要的治疗措施。34例中也见到PH正常和偏碱的休克病例,系休克前有严重的电解质紊乱造成代谢性碱中毒之故。在抢救休克的过程中,发生碱中毒者达55.88％,其重要常见诱因有:(1) 投用碱性药物过多;(2)呕吐或胃肠减压;(3) 低钾等电解质紊乱;(4) 过度换气等。对于各种酸碱紊乱应通过血气分析正确认识,恰当处理。通过血气监护还有利于指导抢救用药、发现电解质紊乱、诊断疑难病例及提高对ARDS的早期发现和指导心肺复苏。pH低于7.0及BE值进行性降低,示预后不良。总之,血气监护并结合临床是一种有效的工具。
Blood gas monitoring increases our understanding of the various acid-base disorders that exist during shock. In this paper, 34 cases of shock in the past five years were analyzed. Metabolic acidosis is the main type of acid-base disorder in shock (n = 9). It is an important therapeutic measure to administer basic drugs timely and appropriately. 34 cases also seen PH normal and alkaline shock cases, Department of Department of shock before a serious electrolyte imbalance caused by metabolic alkalosis. In the process of rescuing shock, alkalosis occurred 55.88%, the most common inducement are: (1) cast overdose of alkaline drugs; (2) vomiting or gastrointestinal decompression; (3) low potassium and other electrolyte disorders ; (4) hyperventilation and so on. For a variety of acid-base disorders should be correct understanding of blood gas analysis, appropriate treatment. Blood gas monitoring is also conducive to guide the rescue medication, found that electrolyte disorders, diagnosis of difficult cases and improve the early detection of ARDS and guide CPR. Progression of pH below 7.0 and BE values showed poor prognosis. In short, blood gas monitoring combined with clinical is an effective tool.
