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.

Primary Outcome Measures:
  • Brow Bulging Score [ Time Frame: 30 seconds post intervention compared to baseline ] [ Designated as safety issue: No ]
    The presence of brow bulging will be scored in 2-second intervals for the first 30 seconds for each of the six phases. The percentage of time that brow bulging is observed will then be calculated for each phase.

Secondary Outcome Measures:
  • Facial grimacing score [ Time Frame: 30 seconds post intervention compared to placebo ] [ Designated as safety issue: No ]
    The presence of brow bulging, nasolabial furrowing and eyes squeezing shut will be scored in 2-second intervals for the first 30 seconds for each of the six phases. The percentage of time that all three of these features is observed will then be calculated for each phase.

Estimated Enrollment: 130
Study Start Date: December 2011
Estimated Study Completion Date: January 2014
Estimated Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Topical and intraurethral 2% lidocaine
2% lidocaine gel will be applied for 5 minutes to the external urethral opening. This will be followed immediately by 2% lidocaine gel administration into the urethra using a 24 gauge angiocath for 5 minutes prior to catheterization for urine specimen collection. Children < 7 kg and > 7 kg will receive 1 cc and 1.5 cc, respectively.
Drug: 2% lidocaine gel
Children < 7 kg and > 7 kg will receive 1 cc and 1.5 cc of 2% lidocaine gel, respectively
Other Name: Lidocaine
Active Comparator: Standard of care
According to standard nursing practice, the urethra will be catheterized without anaesthetic gel but using lubricant gel only
Drug: lubricant gel

Detailed 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.
