Summary

The purpose of this study is to determine whether the irrigation or non-irrigation of a simple laceration treated in the emergency department has an effect on the subsequent rate of infection.

Detailed description

Background: Current guidelines recommend that lacerations be irrigated prior to their closure. However, there is very little data in the literature suggesting that simple laceration irrigation diminishes the subsequent rate of infection. Do patients benefit from this practice that involves additional time and costs? Hypothesis Testing \& Procedure: The purpose of this double-blind randomized controlled non-inferiority study is to test the hypothesis that the non-irrigation of lacerations does not increase the rate of post-repair infection. Every adult patients presenting to the Chicoutimi's Hospital Emergency Department with a simple laceration will be identify by the triage nurse. Eligibility will subsequently be assessed by the emergency room physician according to the inclusion and exclusion criteria. Eligible and consenting patients will be randomized to either the irrigation or non-irrigation arm. Post-repair rate of infection and aesthetic appearance satisfaction will be reported. Sample Size Determination: With the fairly liberal inclusion criteria, a 6% wound infection rate in the irrigation group is expected, which corresponds to the upper limit of the 2 to 6% range reported in the literature. Non-inferiority of non-irrigation would be accepted if the rate of infection in this group does not exceed by 4% the usual infection rate of 6% with irrigation, as previously stated. As such, for the study to be powered at 80% with a 95% one-sided confidence interval, a population of 874 patients would be needed to conclude that the non-irrigation is non-inferior when its infection rate does not exceed by more than 4% the infection rate of the irrigation group. In addition, to account for an attrition rate of approximately 10%, enrolment of 1000 patients is aimed. Statistical Analysis: Statistical analysis will be done by a certified statistician. According to the distribution of our data, the Chi2 or the Fisher test will be used. A preliminary analysis of our data will be done in the Spring 2017 to assess safety of our intervention. Plan for Missing Data: Patients that are lost at follow up will be considered as having had no infection if no record of subsequent visits for wound infection is found after consultation of the regional Electronic Medical Record.

Interventions

Type	Name	Description
PROCEDURE	Irrigation	A designated unblinded medical team member (nurse, emergency room physician or resident/trainee uninvolved in that particular patient's care) will prepare the laceration for repair and perform the irrigation. Irrigation will be delivered through a 20 Gauge 1 inch long catheter mounted on a 60 millilitre syringe. The volume of normal saline used will be calculated as 60 millilitre per centimetre length of laceration for a maximum of 300 millilitre. Once completed, the treating physician will enter the room and proceed to the laceration closure with the method and equipment of his choice. Both the patient (through eye covering) and the treating physician will remain blinded to the intervention.
PROCEDURE	No irrigation	A designated unblinded medical team member (nurse, emergency room physician or resident/trainee uninvolved in that particular patient's care) will prepare the laceration for repair. The laceration will not directly be irrigated. In order to ensure blinding of the subjects, the surrounding of the wound will be irrigated with a total of 60 millilitre of normal saline delivered through a 20 Gauge 1 inch long catheter mounted on a 60 millilitre syringe. Care will be taken not to enter a margin of 5cm from the laceration edges. Once completed, the treating physician will enter the room and proceed to the laceration closure with the method and equipment of his choice. Both the patient (through eye covering) and the treating physician will remain blinded to the intervention.
