Epidural Anesthesia

Suppresses surgical stress, has a positive effect on postoperative nitrogen balance, provides a more stable cardiovascular hemodynamics, reduces blood loss, improves peripheral vascular circulation and provides improved postoperative pain control.

Thoracic epidural analgesia associated with a reduction in incidence of urinary retention, decrease incidence of hypotension, reduces myocardial oxygen consumption, pulmonary wedge pressure and pulmonary artery pressure, enhances coronary artery perfusion, improves postoperative pulmonary function and results in less inhibition of the gastrointestinal motility and therefore less ileus.

Arterial pressure decreases after institution of epidural block.
