摘　　要：目的　观察术后持续胃肠减压是否与口服雷尼替丁一样能消除胃内因素对胃粘膜 pH( pHi)测定准确性的影响。方法　 14例无胃肠疾病的住院手术患者 ,在术前首次测胃pHi前 12h、前 2h口服雷尼替丁各 15 0mg ;术后持续经液体分压计 (TRIP)鼻胃管胃肠减压 ,相隔 2 4h再次测胃 pHi。 结果　首次 pHi为7 35± 0 0 3,再次pHi为 7 36± 0 0 5 (P >0 2 0 )。Objective To confirm the effect of continuous gastric decompression on elimination of intragastric factor influence on gastric intramucosal pH(pHi) measurement by nasogastric tonometry.Methods Fourteen inpatients without gastrointestinal diseases took ranitidine 150mg PO at 12h and 2h before first measurement of pHi.After 24h of gastric decompression by nasogastric tomometry,pHi was measured for the second time.Results There was no significant difference in gastric pHi between ranitidine and gastric decompression(7.35±0.03 vs 7.36±0.05,P>0.20).Conclusion Continuously gastric decompression may eliminate the intragastric factor influence on pHi measurement.
