- W2366139736 abstract "Objective: To investigate the relationship between gastric intramucosal pH which indicates tissue oxygen metabolism and conventional clinical indexes used to reflect systemic oxygen metabolism, and the value of pHi as a prognostric index of mortality in critically ill patients. Methods :When a tonometer was confirmed in the lumen of the stomach, PCO 2 in saline was measured together with arterial blood gases, the pHi in the gastric was calculated by Henderson-Hasselbalch equation. In this way ,the pHi immediately and 24 hours later were measured .Then acquired message to appraise APACHEⅡscore.Result :All patients were divided into two groups,one was survivor and the other was dead.There was no difference in Glasgow Coma Score (GCS score) ,pHa and PaO 2/FiO 2 between two groups . The pHi immediately in dead group (7.133±0.374) was lower than in survivor group(7.384±0.062),P0.01. The pHi 24 hours later in dead group (6.911±0.496) was far lower than in survivor(7.434±0.051),P0 001.When the pHi immediately was not more than 7.32,the mortality was 75%,When the pHi 24 hours later was not more than 7.32,the mortality increased to 88.9%.Conclusion:As a message of tissue hypoxia ,the pHi always alter earlier than the usual indicators,the pHi revelant to the mortality .It is a good prognostric index.
