General anesthesia or intravenous sedation is needed in the traditional vasectomy reversal since a traditional approach to vasectomy reversal is to make two big incisions in each side of scrotum. Easy Vasectomy Reversal® with modern no scalpel technique and single mini incision reduces the trauma and pain, therefore, general anesthesia or intravenous sedation is no longer needed in the vasectomy reversal procedure (vasovasostomy).
Conventional needle anesthesia in vasectomy Reversal involves the use of a 27 gauge needle to raise a wheal at the skin of scrotum; it is then advanced to both ends of the vas on each side where further anesthetic solution is deposited. Since the opening is so small in the no-scalpel Easy Vasectomy Reversal®, it is easy to apply anesthesia without the use of needles. A spray applicator (MadaJet®) delivers a stream of anesthetic so fine that it penetrates the skin and diffuses to a depth of about 3/16 of an inch, enough to surround and anesthetize each end of vas tube in turn as it is lifted into position beneath the skin, attaining a close to 100% efficacy rate with no need for supplemental anesthetic in the initial vas grabbing.
The tiny opening in the dime-sized area of numb skin is made with a pointy hemostat: one tip makes a pinpoint opening, then the two tips are used to spread and enlarge the opening to about 1/3 of an inch. Since blood vessels in the skin are spread apart rather than cut, bleeding is less than when a scalpel is used.
Once the vas ends are grabbed and lifted up, the complete local anesthesia is achieved by giving additional anesthetic with a fine needle, usually with no pain at all because of the partial anesthesia achieved with the MadaJet.
