持续监测pHi对于评价严重烧伤休克患者预后的意义

The Significance of Constant pHi Detecting in Prognosis of Severe Burn Shock Patients

目的探讨烧伤早期胃肠缺血 ,胃粘膜 pH值(pHi)降低的发生规律 ,以评价对严重烧伤休克患者预后的意义。方法从血流动力学、胃肠缺血等方面探讨严重烧伤患者早期胃肠缺血的发生规律及对预后的评价。伤后入院立即复苏 ,按国内公式补充平衡液。结果伤后1h胃肠pHi就迅速下降 ,并恢复缓慢 ,伤后72h仍未达正常 ,死亡组 pHi持续<7.32。结论①胃肠缺血发生早 ,恢复慢。②以 pHi<7.32为界值 ,烧伤后 pHi持续降低患者 ,死亡特异性100 % ,敏感性80 % ,持续

Objective To investigate the regulartity of early happening of gastrointestinal ischemia and decrease of pH value in burn patients,evaluate the prognosis of severe burn shock patients.Methods To observe pHi change and anoxia in severe burn shock patients, liquid supplementation with national infusion formula.Results Gastrointestinal pHi was getting lower significantly one hour after burning and was recovering slowly, but not reach normal parameter after 72 hours. pHi was constantly lower than 7.32 in death cases. Conclusions ①Gastrointestinal anemia happens shortly after buming and recovers slowly.②the patients with pHi continuously lower than 7.32 have 100% mortality and sensitivity with 80%. pHi detect was important for the treatment and prognosis in severe burn shock paticnts.
