Objective To compare the effects of target-controlled infusion (TCI) of remifentanil (R) in various doses in combination of TCI propofol (P) on hemodynamic response to tracheal intubation. Methods Fifty ASA Ⅰ - Ⅱ patients (18 male, 32 female) aged 100 bpm) . The TCI system comprised Graseby 3500 infusion pump controlled by computer program Rugloop which included Marsh and Minto pharmacokinetic parameters. Results Induction time (from start of TCI R + P to LOC) was significantly longer in group RO and R2 than that in group R4, R6 and R8 ( P

Objective To compare the effect of pericardial devascularization with that of the modified Sugiura procedure in management of portal hypertension. Methods From 1990 to 2008, 236patients with portal hypertension underwent operations including pericardial devascularization in 147and modified Sugiura in 89 in our hospital. Results There were 12 perioperative deaths (8.2 % ), and 2 rebleedings (2 % ) in the pericardial devascularization group, and 7 perioperative deaths (7.9 % ) and 2 rebleedings(3.4 % ) in the modified Sugiura group. The follow-up rate was 91.9 % in the pericardial devascularization group and 87.8% in the modified Sugiura group respectively, in a period from 6 months to 19 years. The 1-, 3-and 5-year rebleeding rates were 5.7%,15.2% and 25.5% in the pericardial devascularization group and 6.9%, 16.3%, 29.5 % in the modified Sugiura group, respectively. The 1-, 3- and 5-year survival rates were 87.8% ,79.1% and 69.7% in the pericardial devascularization group and 95.8 %,85.0%, 76.9 % in the modified Sugiura group, respectively. Conclusion Modified Sugiura procedure and pericardial devascularization have differences in perioperative mortality as well as rebleeding and survival rates.
