1例50岁男性肺癌患者因肺部感染应用左氧氟沙星,由于疗效不佳欲换用头孢哌酮钠他唑巴坦钠。行皮肤过敏试验约10 min后,患者出现胸闷、心悸、气促、呼吸困难,心率120次/min。考虑为过敏反应,立即给予地塞米松10 mg静脉推注,行心电监护。1.5 h后,患者胸闷、气促及呼吸困难等症状改善,血气分析示二氧化碳分压26 mm Hg(1 mm Hg=0.133 kPa),氧分压47 mm Hg,实际碳酸氢盐19 mmol/L,标准碳酸氢盐22 mmol/L,pH 7.49。8 h后,患者过敏反应症状消失。
One case of 50-year-old man with lung cancer due to pulmonary infection levofloxacin, due to poor efficacy to switch to cefoperazone sodium tazobactam sodium. About 10 min after skin allergy test, the patient developed chest tightness, palpitation, shortness of breath, difficulty breathing and heart rate 120 beats / min. Considered as an allergic reaction, immediately given dexamethasone 10 mg intravenous injection, line ECG. After 1.5 hours, the symptoms such as chest tightness, shortness of breath and dyspnea were improved. The blood gas analysis showed that the partial pressure of carbon dioxide was 26 mm Hg (1 mm Hg = 0.133 kPa), the partial pressure of oxygen was 47 mm Hg, the actual bicarbonate was 19 mmol / L, The standard bicarbonate 22 mmol / L, pH 7.49.8 h, the patient’s allergic symptoms disappear.
