Abstract
Se analizaron los cambios hemodinámicos producidos en 30 pacientes que fueron sometidos a cirugía de revascularización miocárdica sin circulación extracorpórea. Los parámetros medidos mediante el doppler esofágico fueron: frecuencia cardíaca, presión arterial media, gasto cardíaco, índice cardíaco, resistencia periférica, volumen sistólico y presión venosa central. Los controles se realizaron durante la disección de la arteria mamaria (basal), durante la realización de cada anastomosis y 5 min después del retiro del inmovilizador (final). Se utilizó el Octopus como estabilizador epicárdico. La frecuencia cardíaca aumentó durante la realización de las anastomosis de las arterias DA, CX y DP. La presión arterial media disminuyó significativamente durante la realización de la anastomosis a la CX. El volumen sistólico disminuyó durante la realización de la anastomosis a la DA y CX. Los valores de la presión venosa central aumentaron durante la realización de las anastomosis de las arterias CX y DP. En la mayoría de los casos los cambios hemodinámicos que se produjeron en la cirugía sin circulación extracorpórea pudieron corregirse y no imposibilitaron la realización de esta técnica
The hemodynamic changes observed in 30 patients that underwent myocardial revascularization surgery without extracorporeal circulation were analyzed. The parameters measured by esophageal doppler were the following: heart rate, mean arterial pressure, heart output, peripheral resistance, systolic volume and central venous pressure. The controls were carried out during the dissection of the mammary artery (basal), during the performance of anastomosis and 5 minutes after the removal of the immobilizer (final) The Octupus was used as an epicardiac stabilizer. Heart rate increased during the anastomosis of the DA, CX and DP arteries. The mean arterial pressure decreased significantly during the anastomosis of CX. The systolic volume was reduced during the anastomosis of DA and CX. The values of the central venous pressure rose during the anastomosis of CX and DP. In most of the cases, the hemodynamic changes that occured in surgery without extracorporeal circulation could be corrected and they did not hinder the application of this technique
