Paediatric Acute care Guidelines PMH Emergency Department

Background

Paraphimosis develops if the foreskin is retracted, and is left retracted for a significant period of time. The tight band caused by the retracted foreskin results in congestion and swelling of the glans, making it difficult for the foreskin to be returned to its normal position. The unreducible paraphimosis in the ED setting warrants an urgent surgical review.

Phimosis is circumferential scarring and narrowing of the edge of the
foreskin, resulting in a foreskin, which is non-retractile or difficult to retract. This may predispose to paraphimosis if the foreskin is retracted, and to balanitis.

Balanitis refers to infection of the foreskin and glans. Paraphimosis can be misdiagnosed as balanitis. It is important to check the position of foreskin in relation to glans and distinguish between balanitis and paraphimosis. Refer to Balanitis for treatment. 

Assessment

Management

  • Most can be gently reduced in he ED. The unreducible paraphimosis is a surgical emergency.

If you are unfamiliar with the reduction technique seek early surgical advice

  • Analgesia and topical anaesthesia are important, as a paraphimosis can be very painful.
    • It is useful to gently apply topical 2% lignocaine gel or EMLA® cream as soon as the child arrives in emergency, to allow time for topical anaesthesia to occur.
    • A cloth-covered ice pack applied intermittently to the swelling may be a useful adjunct.
    • The choice of analgesia should be made on assessment of the child’s distress and it may be appropriate to use oral Painstop, titrated intranasal Fentanyl or inhaled N2O. One may need to modify the approach to keep the child comfortable and non-distressed.
  • Technique: Usually the patient presents early and manual reduction of the foreskin may be attempted in the Emergency Department.
    • Following administration of adequate analgesia and sedation, gentle digital circumferential pressure is applied to the swollen glans to reduce oedema. This process requires patience and may take up to 10 minutes.
    • The intention is not to suddenly force the foreskin but to apply constant pressure distal to the foreskin band (greater than arterial pressure), thus slowly shrinking the glans as the oedema settles. This will eventually allow the foreskin to gently slip forward over the glans.

    • There is no need to prescribe antibiotics.
    • Osmotic agents may reduce oedema prior to reduction – use gauze soaked in 20% mannitol or 50% glucose.

If successful and the patient is able to pass urine normally, he may be discharged with simple analgesia and advised not to retract the foreskin for prolonged periods. 

  • Failed reduction: If this fails, or if the patient presents with severe swelling of the glans, the child should be kept fasted and be referred urgently to a paediatric surgeon.
