Investigating The Relationship Between Hemodynamic And Metabolic Parameters In Portal Triade Occlusion Following Hemorrhagic Shock.

PURPOSE: To determine whether metabolic and hemodynamic parameters are "mathematically" coupled in rats submitted to portal triad occlusion following controlled hemorrhagic shock state. METHODS: Pearson's coefficient (r-value) analysis was performed. Differences considered significant at p r > 0.50. RESULTS: It was observed that there is a direct proportional relationship to HCO3- with pCO2 (r = 0.66), base deficit (r = 0.87) and inverse with serum lactate (r = -0.54). pCO2 was directly associated with MAP (r = 0.51), and inversely with pH (r = -0.64). Hematocrit was directly associated with HR (r = 0.72) and CI (r = 0.76), and serum lactated was inversely associated with base deficit (r = -0.61). CONCLUSION: In rats submitted to Pringle's maneuver during 15 minutes following hemorrhagic shock state, there is a mathematical coupling with a very good correlation between several hemodynamic and metabolic variables.201222

Anatomic Study Of Portal Vein. Transpancreatic Vessels Injuries Approach

Introduction: The commitment of the great blood-vessels make up a situation of great complexity and a high rate of the complications and mortality patients with abdominal trauma. The injury of the portal vein matters because of the difficulty on the diagnosis and the approach surgery. Objective: To set the standard on the transverse section of the pancreas looking for a safer surgical access to repair the portal vein injuries. Methods: A quantitative analysis was performed to characterize the anatomical relationship between the portal vein and their tributaries relating them to the pancreas. On these corpses, the measurements of a anatomical triangle were studied. It base was the upper limit of the superior mesenteric vein and the initial portion of the portal vein; the apex, a point located on the upper limit of the confluence of the splenic vein and superior mesenteric vein, situated at the middle line of the superior mesenteric vein. Results: The portal vein is formed 3.24cm from the internal border of the duodenal arc at a distance of 1.61cm and 1.07 from the inferior and superior pancreas borders, respectively. Conclusion: The present study allow us to conclude that, to have access to the origin of the portal vein, in case of trauma of this vessel, one should proceed a transverse section of the neck of the pancreas next to the superior mesenteric vein, because its confluence with splenic vein occur, on average, 1.07cm and 1.61cm from the superior and inferior border of the gland, respectively.174225231Aleksandrovich, G.L., Rudenko, I.I., Injury of majors blood vessels in abdominal trauma (1991) Khirurgiia (Mosk), 12, pp. 66-69Dawson, D.L., Johansen, K.H., Jurkovich, G.J., Injuries to the portal triad (1991) Am J Surg, 161 (5), pp. 545-551Jurkovich, G.J., Hoyt, D.B., Moore, F.A., Ney, A.L., Morris, J.A., Scalea, T.M., Patcher, H.L., Davis, J.W., Portal triad injuries (1995) J Trauma, 39 (3), pp. 426-434Tyburski, J.G., Wilson, F.R., Dente, C., Steffes, C., Carlin, A.M., Factors affecting mortality rates in patients with abdominal vascular injuries (2001) J Trauma, 50 (6), pp. 1020-1026David Jr., J.K., Gomez, G.A., Trauma management (1989) Abdominal Vascular Trauma. 1 Ed., pp. 306-307. , David BP.
