title: The relationship between the mean arterial blood pressure values obtained with the Peñaz non invasive method and those obtained with the invasive intraarterial.
abstract: It was investigated the relationship between the mean arterial pressure values obtained through the Peñaz method (non invasive) with those obtained intraarterially (invasive) in patients under balanced general anesthesia with the aim of establishing the influence of the different anesthetic stages upon such relationship. Anesthesia was induced with thiopental and anesthetic maintenance with halothane and intermittent doses of fentanyl and a muscle relaxant. EKG, servo-plethysmograph, central venous and radial artery catheter, were placed in each patient thus obtaining in this manner HR, FAP, CVP and IAP readings. The relationship between finger arterial pressure and intraarterial pressure values was high in the different anesthetic stages. It was concluded that the readings obtained with the Peñaz method are not significantly affected by balanced general anesthesia.
