Overview

Perineal innervation.
  • Perianal blocks have been shown to be comparable to general anesthesia for in terms of pain control in anal procedures including surgeries [1]
  • "Perianal block is a safe, feasible, reliable, and reproducible mode of anesthesia." [2]


Indications


Contraindications

  • Overlying infection
  • Allergy to chosen anesthetic
  • Uncooperative patient


Equipment Needed

  • 20 cc Syringe with a 27 Gauge Needle
  • Spare 18 Gauge Needle (to draw up anesthetic)
  • Local Anesthetic (e.g. Lidocaine or Bupivacaine)
  • Silk Tape
  • Pillow or Blankets
  • Packaged, Moist Towelette


Procedure[3]

  • Obtain informed consent
  • Place the patient in the prone position, placing either a pillow or blankets under their hips for comfort and ideal positioning
  • Using tape, separate the patient's buttocks from one another to better visualize the perianal area
  • Draw up anesthetic into 20 cc syringe using 18 Gauge Needle
  • Ensure that the perianal area is clean by removing debris with moist towelette
  • Peripheral to the anal sphincter, choose multiple injection sites that allow for fanning circumferentially around the anus
  • Advance 27 Gauge needle into one of these preselected areas
  • Aspirate to rule out intravascular placement prior to injecting 3 -5 mL of anesthetic
  • Continue to the other preselected areas, fanning the needle circumferentially in order to surround the anal area with local anesthetic
