Celsior液与UW液对无心跳大鼠供肝保存效果的比较

Objective To compare the effects of Celsior (CS) solution vs University of Wisconsin (UW) solution on preservation of non-heart- beating donor (NHBD) livers in rats. Methods The healthy male SD rats were taken as donors and recipients. The thoracic descending aorta and supradiaphragmatic inferior vena cava were cross-clamped for 10 min to induce ischemia as a NHBD model. After flushed with the cold CS or UW solution, NHBD livers were stored at 4℃ for 8 h or 16 h. Then they were transplanted using the two-cuff technique with arterial reconstruction. Accordingly, the recipients were divided into four groups: CS 8 h, UW 8 h, CS 16 h and UW 16 h groups. The bile discharge, liver enzymes (ALT and AST), ET-1, IL-1 and TNF-alpha levels in serum at 1, 3, and 6 h after reperfusion were measured. Histopathological examination was carried out by HE staining, and the 7-day survival rate was observed. Results As compared with a homogenous appearance in the NHBD livers perfused with CS solution, the NHBD livers perfused with UW solution showed a heterogenous appearance, with more or less mottling. In the CS 8 h group there were more bile discharge at 1 h, lower ALT and AST levels at 1, 3 and 6 h, and lower serum ET-1, IL-1 and TNF-alpha ? levels at 1 and 3 h after reperfusion than the UW 8 h group (P<0.05). Histopathological examination showed a well-preserved hepatic architecture, milder portal congestion and inflammatory infiltration in CS 8 h group as compared with UW 8 h group. The 7-day survival rate in CS 8 h and UW 8 h groups was 58.3% and 25.0% respectively (P<0.05). There were no significant differences in bile discharge, ALT, AST, ET-1, IL-1 and TNF-alpha ? levels at different time points between CS 16 h and UW 16 h groups (P>0.05), and histopathological examination showed no much difference in the tissue damage between two groups; all recipients died within 3 days (P>0.05). Conclusion CS was more effective than UW in preserving NHBD livers after 8 h of cold storage, which may be due to the better perfusion of CS and inhibition of Kupffer cells, but it had better preserve NHBD livers with CS no more than 16 h.

University of Wisconsin solution versus Celsior solution in clinical pancreas transplantation

INTRODUCTION: This study compared the safety and efficacy of University of Wisconsin solution (UW) and Celsior solution (C) in pancreas transplantation (PTx). METHODS: A retrospective review of 154 PTx performed over a 61-month period included 77 grafts preserved with UW and 77 with C. The two groups were comparable for both donor and recipient characteristics. RESULTS: After a mean cold ischemia time of 624 minutes (range 360 to 945 minutes) for UW versus 672 minutes (range 415 to 1005 minutes) for C (P = NS), no primary endocrine nonfunction occurred. Delayed endocrine function was diagnosed in two grafts in the UW group (2.6%) versus none in the C group (P = NS). After a minimum follow-up of 4 months (mean 26.5 +/- 15.2 months), 22 recipients (UW = 11 vs C = 11; P = NS) required relaparotomy. Overall, 18 pancreata were lost due to either patient death with functioning graft (UW = 4 vs C = 1; P = NS) or graft loss due to other reasons (UW = 8 vs C = 5; P = NS). Actuarial 1- and 5-year patient survival rates were 93.5% and 86.8% for UW compared with 98.7% and 98.7% for C (P = .04). Actuarial graft survival rates at the same times were 88.3% and 75.0% for UW compared with 90.4% and 90.4% for C (P = NS). CONCLUSIONS: Within the range of cold ischemia times reported in this study, UW and C show similar safety and efficacy profiles for PTx.

Comparison of histidine-tryptophan-ketoglutarate solution and University of Wisconsin solution in adult liver transplantation

BACKGROUND: A safe and effective preservation solution is a precondition for successful orthotopic liver transplantation (OLT). This study compared University of Wisconsin (UW) and histidine-tryptophan-ketoglutarate (HTK) solutions in OLT. PATIENTS AND METHODS: We retrospectively reviewed the medical records of 137 primary cadaveric. OLT performed between January 2003 and December 2006 at our institution. Sixty-eight grafts were harvested using UW and 69 using HTK. Recipients were managed similarly in regard to operative techniques and immunosuppression. We collected donor data including serum transaminases, serum sodium, ICU stay and assessed macroscopic liver quality. Recipient serum transaminases were collected on postoperative days 1, 7, 14, and 30. We compared biliary and vascular complications, as well as patient and graft survivals. RESULTS: Mean serum bilirubin levels were slightly higher in the HTK group at 1,7,14, and 30 days after transplantation, whereas transaminases were higher in the UW group. Primary nonfunction occurred in 1 patient in each group. Retransplantation was performed in 5 patients in the UW and in 9 patients in the HTK group. Biliary complication rates were similar in the UW and HTK groups (22% and 17%, respectively). Six arterial complications occurred in the HTK (8.7%) and 2 in the UW group (2.9%; P < .05). Mean follow-up was 25 months. Graft survival at 1, 12, and 36 months was 90%, 78%, and 75% versus 90%, 71%, and 71% in the UW versus HTK groups, respectively. One-, 12-, and 36-month patient survival rates were 93%, 78%, and 75% versus 93%, 78%, and 78% in the UW versus HTK groups, respectively. CONCLUSIONS: There were no significant differences in graft and patient survivals between the 2 groups. Whereas the biliary complication rates were comparable in both groups, the arterial complications were clearly higher in the UW group (8.7% vs 2.9%; P < .05%). UW and HTK solutions seemed to be equally safe and effective in the preservation of liver grafts. The high incidence of arterial complications in the UW group requires further prospective studies.     

Comparative study on the effects of acetated Ringer's solution,lactated Ringer's solution,Ringer's solution,and 5% glucose-acetated Ringer's solution on canine hemorrhagic shock

The abilities of acetated Ringer's solution (AR), lactated Ringer's solution (LR), Ringer's solution (R), and 5% glucose-acetated Ringer's solution (AR-D) to improve canine hemorrhagic shock were investigated. All solutions studied were infused at 1 ml·kg⁻¹·min⁻¹ for 90 min after base excess (BE) reached about −13 mEq·l⁻¹ by maintaining the mean blood pressure (MBP) at 40 mmHg. MBP, renal blood flow (RBF), vertebral blood flow (VBF), and urinary output significantly increased after the start of infusion of AR, LR, R, and AR-D. The VBF and urinary output were particularly improved with AR-D. The arterial blood level of HCO ₃ ⁻ and BE were also increased after the start of infusion of AR, LR, and AR-D but not of R. AR infusion improved BE more effectively than LR. Although AR-D, AR, and LR increased HCO ₃ ⁻ , the blood pH did not increase in AR-D. The value of plasma acetate increased after the start of infusion of AR and AR-D but not of LR, and R. On the other hand, plasma lactate and pyruvate levels were higher with LR than with AR. The increase in the lactate/pyruvate ratio induced by LR was larger than that by AR. The plasma norepinephrine and epinephrine levels decreased after the start of all infusions. Plasma insulin and glucose levels were markedly increased after the start of AR-D infusion but were not affected by AR, LR, and R. These results indicate that the effectiveness of various infusion solutions such as AR, LR, R, and AR-D during canine hemorrhagic shock varies. AR-D may be useful for increasing both peripheral blood flow and urine output. AR may also be useful for improvement in metabolic acidosis and surgical diabetes induced by hemorrhagic shock.
