ISCHEMIA, EVENT, MINOR, SECONDARY, NECROSIS
In the past, local anesthetics associated with a vasoconstrictor should not be administered to extremities because it causes ischemia, with the worst event being digit necrosis. In a review of the literature from 1880 to 2000, one author noted that most reported cases of finger necrosis were not associated with the use of adrenalineMinor surgical hand procedures are usually performed under local anesthesia and sedationIn the WALANT technique, the surgery is performed with the patient awake and injection of solution with 9 mL of 1% lidocaine with adrenaline and 1 mL of 8.4% sodium bicarbonateThe primary objective of this study was to compare the WALANT technique with the local anesthesia technique associated with sedation regarding pain intensity for minor hand surgical procedures. The secondary objective was to compare the need for complementary analgesics.
