Combination of Regional Anesthetic Blocks for Femoropopliteal Bypass Surgery

Abstract

We have read with great interest the article by Basagan-Mogol et al1Basagan-Mogol E. Turker G. Yilmaz M. et al.Combination of a psoas compartment, sciatic nerve, and T12-L1 paravertebral blocks for femoropopliteal bypass surgery in a high-risk patient.J Cardiothorac Vasc Anesth. 2008; 22: 337-339Abstract Full Text Full Text PDF PubMed Scopus (8) Google Scholar entitled “Combination of a Psoas Compartment, Sciatic Nerve, and T12-L1 Paravertebral Blocks for Femoropopliteal Bypass Surgery in a High-Risk Patient.” It is known that general anesthesia increases postoperative complications, and central neuraxial blocks may cause serious sympathetic block and hemodynamic side effects in high-risk patients. For these reasons, peripheral regional anesthesia is generally preferred in high-risk patients. Basagan-Mogol et al1Basagan-Mogol E. Turker G.

Bupivacaine is usually used at the minimum concentration (0.25%) required for surgical anesthesia to reduce the risk as much as possible.3Naja Z. el Hassan M.J.

In our experience, this technique achieves good patient and surgeon satisfication during and after the surgical period. We believe that bupivacaine 0.25% is a sufficient concentration and provides adequate analgesia and safe anesthesia for high-risk patients undergoing femoropopliteal bypass surgery.

It can be difficult to decide the type of anesthesia in high-risk vascular surgical patients. Although femoropopliteal bypass surgery is usually performed under general anesthesia or central nerve blocks, peripheral regional anesthesia could be a good choice especially in high-risk patients.1,2 We report a high-risk patient who presented for lower-limb revascularization with femoropopliteal bypass surgery.
