A Study to Assess the Ability of 2% Lidocaine Gel to Reduce the Discomfort of Urethral Catheterization

Urinary Tract Infection Clinical Trial

Official title: A Randomized Blinded Controlled Trial of 2% Lidocaine Gel Compared to Standard of Care in Children Undergoing Urethral Catheterization

Status Completed

Clinical Trial Summary

Children 0-24 months of age requiring a urethral catheterization for urine collection will be randomized to receive either topical and intraurethral 2% lidocaine or standard of care to assess for the effectiveness of the former in minimizing pain during urethral catheterization. It is hypothesized that administration of 2% lidocaine gel both topically and intraurethrally will confer a greater degree of pain reduction compared to standard of care.

Clinical Trial Description

An estimated 10% of children 0-24 months of age that present to the emergency department (ED) with fever and/or vomiting have a urinary tract infection (UTI). An accurate diagnosis of a UTI ensures timely and appropriate treatment given to reduce the risk of renal scarring, which is the greatest in this age group. To ensure diagnostic accuracy, urethral catheterization is the preferred method to obtain a urine sample from a young child. In contrast to adults, most children do not receive local analgesia for urethral catheterization; despite growing recognition that children experience avoidable pain and discomfort during invasive procedures.

Following informed consent, participants will be randomized by block randomization in a concealed fashion to receive either topical and intraurethral 2% lidocaine or standard of care using a computerized random number generator. The research nurse will access a sequentially numbered, opaque sealed envelope that will contain the participant's group assignment. No adjunctive analgesic methods will be used. A research pharmacist will prepare 2% lidocaine gel in a 3 cc syringe attached to a 24 gauge angiocath. Children < 7 kg and > 7 kg will receive 1 cc and 1.5 cc, respectively (2).

The entire procedure will be videotaped and participants pain will be scored using a brow bulging score and visual analogue scale by independent, blinded raters. ;
