RESUMEN
Objective To evaluate perioperative fluid infusion strategies in retroperitoneal tumor patients.Method Data of 89 retroperitoneal tumor patients in Peking University People's Hospital and Peking University International Hospital were collected and devided into intraoperative minor haemorrhage group (761 ml) and massive haemorrhage group (4 813 ml),including postoperative fluid treatment,input and output volume,serum brain natriuretic peptide level and postoperation complications.Results Fluid input on the 1st day after operation,the 2nd day,the 3rd day respectively were (7 565 ±4 757),(3 869 ± 727),(3 289 ± 897),(3 096 ± 567) ml in the minor haemorrhage group,and (13 927 ± 5 612),(5 192 ± 1 274),(3 786 ± 1 137),(3 797 ± 719) ml in the massive haemorrhage group (t =-4.637,-3.117,-2.460,-2.982,P =0.04,0.048,0.36,0.038).BNP level respectively were (33 ±25),(82 ±66),(116 ± 54),(145 ± 75) ng/ml in the minor haemorrhage;respectively,(70 ± 65),(165 ± 153),(256 ± 220),(442 ± 412) ng/ml in the massive haemorrhage group (t =-4.637,-3.117,-2.460,-2.982,P =0.041,0.038,0.046,0.04).The accumulative percentage of negative fluid balance was 100％ in 3 days after operation.Acute kidney injury (AKI),cardiac,respiratory events,major intraabdominal complications deep venous thrombosis developed in minor and massive haemorrhage group were 4.7％,7.1％,4.7％,14.3％,9.5％ vs.25.1％,27.6％,46.8％,10.6％,17.0％ respectively (x2 =2.89,5.89,19.96,0.044,0.674,P=0.049,0.015,0.001,0.834,0.412).Conclusions Multiple goals directed fluid strategy leads to a better outcome by decreasing the AKI rate.BNP level could be used as a goal marker in fluid treatment.
RESUMEN
AIM: To determine the evolutionary pattern of parenchymal cell apoptosis in multiple organs early after intestinal ischemia-reperfusion(I/R) and its induction mechanisms and the role of apoptosis in triggering SIRS/MODS. METHODS: An I/R model was reproduced by clipping and releasing the superior mesenteric artery in rats and mice. Flow cytometry, electron microscope, DNA agarose gel electrophoresis, TUNEL method, fluorescent and Gomori's silver-HE staining were used to detect apoptosis. Distribution features of apoptotic parenchymal cells in multiple organs were observed. Immunohistochemical staining of HSP 70 and Bcl-2 were performd to study the induction mechanisms of apoptosis.RESULTS and CONCLUSION: 1. Damage of the liver, lung, gut and kidney was appeared in early phase of I/R. The percentages of apoptosis in parenchyma organs increased progressively. The percentages of cell necrosis increased with the prolonged I/R duration. 2. Percentages of apoptosis were much higher near the central veins of liver lobules, in the outer medulla of the kidney, and the antimescenteric border of intestinal mucosal epithelium because of ischemia. 3. The expression of HSP 70 increased and Bcl-2 reduced in the areas mentioned above because of hypoperfusion. 4. Apoptosis of I/R hepatocytes, splenocytes and thymocytes was obviously increased after Kupffer cell blockage with GdCl3, showing the functional state of Kupffer cells may play an important role in SIRS/MODS.
