Abstract:
Objective To investigate the ch an ges of gastric intramucosal pH (pHi) during orthotopic liver transplantation (OL T) without venovenous bypasss. Methods Twenty patients (14 males and 6 females) aged (46.7 ?4.6) years, undergoing orthotopic liver transplantation without venovenous byp asss, were included in this study. A gastric tube technique was used to draw gas tric juice 3～5 mL to determine pHi and PiCO 2 before OLT, at 20 min preanhep atic phase, 30 min anhepatic phase, 30 min new hepatic phase and at 2 h and 2 4 h after operation. The arterial blood samples collected taken for the measure ments of PaCO 2, PO 2, pH, BE and HCO 3- at the same time point s as above. pHi was calculated through Henderson-Hasselbach equation. Results The gastric intraumucosal pH (pHi) was decreased significant ly at the time points of 30 min anhepatic phase and 30 min new hepatic phase c ompared with before operation (P
