Paravertebral blockade with propofol sedation versus general anesthesia for elective endovascular abdominal aortic aneurysm repair.
The objective of this study was to evaluate the applicability of paravertebral blockade (PVB) for endovascular abdominal aortic aneurysm repair compared with general anesthesia (GA). Data from patients who underwent elective infrarenal endovascular abdominal aortic aneurysm repair between August 2001 and July 2002 using PVB or GA were retrospectively reviewed and compared with respect to risk factors, intraoperative hemodynamic characteristics, operative outcome, and complications. Ten patients underwent elective infrarenal endovascular abdominal aortic aneurysm repair under PVB, whereas 15 patients were operated on under GA. One conversion from PVB to GA was necessary for block failure. The perioperative (< 30 days) cardiovascular morbidity and overall mortality were zero in both groups. The PVB group benefited significantly with respect to the incidence of intraoperative hypotension (p < .05) and blood pressure lability (p < .01), as well as postoperative nausea (p < .01). Our preliminary results indicate that PVB is feasible and can be performed safely in a patient population with significant comorbidities.
