History of Changes

Purpose

Patients in the intensive care unit (ICU) often require blood pressure support of vasoactive drugs such as amines. Finger necrosis (so called "blue toe syndrome") is a well documented phenomena with incidence reaching as high as 60% in patients receiving vasopressin. Botulinum toxin is a known muscle relaxant used for a variety of medical application. Recently, several reports have demonstrated its effect in vasospastic disorders. It has also been in mice that when administered locally it has a local vasodilatory effect. The goal of this experiment is to compare the effect of Botulinum Toxin administered locally on amine induced finger necrosis.

Arms	Assigned Interventions
Active Comparator: Treatment Injection of 200 units of Botulinum Toxin A (BOTOX) to a treated limb. Each limb will be divided to two levels - arterial arch and digital arteries (near MCP/MTP) levels. In each level 100 units of Botox will be injected in 6 injection points in the proximity of the arteries.	Drug: Botox Injection of 200 units of Botulinum Toxin A (BOTOX) to a treated limb. Each limb will be divided to two levels - arterial arch and digital arteries (near MCP/MTP) levels. In each level 100 units of Botox will be injected in 6 injection points in the proximity of the arteries.
Placebo Comparator: Control Injection of 0.5cc of normal saline (0.9% NaCl) to each injection site as in the Active drug arm.	Drug: Placebo Injection of 0.5cc of normal saline (0.9% NaCl) to each injection site as in the Active drug arm.
