Abstract
Injury of thoracic nervus vagus could cause the high rate of 25% cardiac complications after esophageal resections. Cardiac and hemodynamic parameters were measured in an animal investigation after different intrathoracic procedures (pigs, each group n = 7, group I — thoracoscopy, II — thoracoscopy and section of vagus, III — thoracoscopic esophageal resection, IV — esophageal resection and section of vagus). After section of nervus vagus together or without esophageal resection heart rate (figure 1), preload recruitable strokework and cardiac index increased significantly whereas relaxation time and vascular resistance decreased (each p < 0,05). The injury of nervus vagus during esophageal resection could cause the increased rate of cardiac complications.
