# Penile Subcutaneous Ring Block

## Overview

This module describes how to anaesthetise the penis using a subcutaneous ring block.

## Indications

## Contraindications

## Patient information and consent

Always verify your patient’s identity and obtain informed consent before proceeding.

### How do I explain this procedure?

“I need to give you an injection that will stop your penis from feeling pain while we do the procedure.”

### What can my patient expect?

“I am going to prick your skin three times with a needle and inject numbing medication around the base of the penis. Each injection might sting a bit, but after that your whole penis will be numb for a short while. The numbness will wear off by itself.”

### What is my patient’s role?

“Let me know if you have any allergies. Fearing blood or needles is normal, but tell me if you have fainted from it. Try to keep still while I give you the injections.”

## Preparation

### Documentation

### Equipment

## Site & Positioning

Position the patient supine.

## Procedure

Follow medical asepsis with non-sterile gloves.

## Troubleshooting

My patient is still feeling pain.

Make sure you wait a full 10 minutes before testing the patient’s sensation. If there is still pain, make sure you injected enough anaesthetic into the entire area. Check the anaesthetic expiry date. Local infection can also reduce the effectiveness of local anaesthetics. Rarely, some patients may be resistant to local anaesthetics.
