Mensuração de pressão venosa central por meio de cateteres venosos central e periférico: comparação entre os valores obtidos em cães e elaboração de índice de correção

The Central Venous Pressure (CVP) is a very important pattern for monitorization in many clinical, surgical and experimental procedures, and it reflects the blood pressure that returns to the right heart side. For its measurement a Central Venous Catheter (CVC) must be used inside the jugular vein. Because of the high cost of the CVC, an option was taken to measure the CVP with a Peripheric Venous Catheter (PVC) inside the jugular vein, with low cost. The CVP measure obtained with the PVC must be subtracted to a reduction index, in this way the measure would correspond to the ones done with the CVC. This study alouds to conclude that the PVC is adequate for CVP measurement in dogs.
