Circumcision (Male; Newborn and Infant)

Chapter 237 Circumcision (Male; Newborn and Infant)



DESCRIPTION


Male circumcision is the removal of some or all of the foreskin of the phallus.



INDICATIONS


Parental or religious preference (not a medically indicated procedure). Circumcision of newborns should be performed only on healthy and stable infants.



CONTRAINDICATIONS


Age greater than 6 to 8 weeks (relative), age less than 12 hours, ambiguous genitalia, hypospadias, illness, less than 1 hour postprandial, possibility of blood dyscrasia, prematurity, undescended testicles (relative). A family history of intolerance or allergy to local anesthetics should prompt reconsideration.



REQUIRED EQUIPMENT



• Infant restraint board (“papoose” board)

• Sterile gloves

• Sterile drape (one with a small fenestration or multiple drapes)

• Skin preparation materials (e.g., povidone–iodine and 70% isopropyl alcohol)

• Sterile gauze pads (2″ × 2″ or 4″ × 4″)

• Three hemostats (small tips, two curved, one straight)

• Small scissors or scalpel (#10 or #11 blade)

• Flexible blunt probe

• Gomco clamp (1.1 to 1.45 cm) or Plastibell (1.3 to 1.6 cm) or Mogen clamp (for clamp methods)

• Sterile safety pin, clip, or skin staple (optional)

• Viscous lidocaine (2% to 5%) or 1% lidocaine without epinephrine, 1-cc syringe, 27-gauge needle for dorsal penile nerve or ring block. EMLA cream may also be used.

• Petrolatum (Vaseline) gauze

• Silver nitrate stick or Monsel solution

• Small suture (3-0 or 4-0 absorbable) and needle holder (available)

Electrosurgical devices should never be used in conjunction with any of the clamp-based procedures.


A bulb syringe should be kept near during circumcision as a protection against aspiration should the newborn regurgitate.



TECHNIQUE


All circumcision techniques begin with the undiapered newborn restrained on an infant restraint (papoose) board. The penis should be inspected to identify the meatus and its location on the glans. Once the anatomy has been confirmed to be normal, anesthesia by way of topical lidocaine or dorsal block may be administered.


Swaddling, sucrose by mouth, and acetaminophen administration may reduce the stress response but are not sufficient for the operative pain and cannot be recommended as the sole method of analgesia. EMLA cream, dorsal penile nerve block, and subcutaneous ring block are all reasonable options, although the subcutaneous ring block may provide the most effective analgesia.


Identifying the depth of the root of the penis using the index finger begins a dorsal penile block. The root is usually located 0.75 to 1 cm beneath the skin surface, with the size and consistency of a large blueberry. The skin of the penis and the surrounding areas should be disinfected by any suitable method and sterile drapes should be placed to provide a surgical field. Using aseptic technique, the physician places the penis on slight downward traction and inserts the needle at the 2 o’clock position near the base. The needle is passed in a posteromedial direction to a depth of 3 to 5 mm beneath the skin, about 5 to 7 mm distal to the penile root near the point at which the dorsal nerves branch. If it is correctly located outside of the corpus cavernosum, the tip of the needle should move freely. The syringe should be aspirated to prevent intravenous injection, and 0.2 to 0.4 mL of anesthetic should be injected. The procedure is repeated at the 10-o’clock position, although a single needle insertion point in the dorsal midline may also be used, if desired. Total anesthetic dose should remain less than 0.8 mL. Full anesthesia will be achieved in 2 to 4 minutes.
