Urinary infection is one of the most common bacterial infections in pediatrics and requires urine collections to be diagnosed. In France, among children under 3, urine samples are collected thanks to collecting bags.

Work teams have set as their main goal to compare the different levels of acute pain involved for children under 3 during the removing of the collecting bag, depending on the use, or not, of the Oiled-limestone liniment (randomized into 2 parallel groups), with, as a main endpoint, the difference between the results assigned to the acute pain by a pain evaluation scale (FLACC: Face-Legs-Activity-Cry-Consolability).

Urinary infection is one of the most common bacterial infections in pediatrics and requires urine collections to be diagnosed. In France, among children under 3, urine samples are collected thanks to collecting bags. This nursing care, extensively recommended for young children, was the subject of a study (still in progress) in 2009 conducted by the nurses of the CHU of Limoges and the CHI of Poissy. The results have shown that the removal of the collecting bags could involve pains as severe, or even worse, as the ones observed during a urinary catheter.

The lack of documentation and stunning results of our 2009 study persuaded healthcare teams to carry on their researches and posed the following problem: the removal of the collecting bags can cause an acute pain which could result in a major discomfort for a child under 3.

In practice, the removal of the collecting bag is made without any special precautions, or with the use of several products such as the Oiled-limestone liniment. This non-medicated product, commonly used for the care of the infant seat, intra and extra hospital field, would facilitate the removal of adhesives and plasters, according to the empirical experience of caregivers. Work teams have set as their main goal to compare the different levels of acute pain involved for children under 3 during the removing of the collecting bag, depending on the use, or not, of the Oiled-limestone liniment (randomized into 2 parallel groups), with, as a main endpoint, the difference between the results assigned to the acute pain by a pain evaluation scale (FLACC: Face-Legs-Activity-Cry-Consolability).

Thanks to studies in usual care among different medical centers, that would be randomized and blindly conducted, healthcare teams would like to verify the hypothesis that the use of Oiled-limestone liniment could reduce acute pain involved in the removal of urine collecting bags among children under 36 months old. The study will be submitted to the parents of children aged 0 to 36 months old admitted to the pediatric emergency and needing a urine sample using a collecting bag.

The method of pain evaluation with the FLACC scale will be carried out as following: a caregiver will remove the collecting bag, with or without the use of the Oiled-limestone liniment, according to a prior randomized draw, and, at the same time, a second caregiver will film the care in order to provide experts assigned to measure objectively the level of the pain felt by the child during the care with videos.

Based on 136 children, during 24 months, this study would imply 3 inclusions in every medical center each month. Each inclusion should last 30 minutes.

Expected benefits would be, at first, improvement in the quality of healthcare for young children and improvement in the practice of the nurses, the nursery nurses, the auxiliaries of child welfare and the caregivers. This study would also suggests new recommendations for a good practice of nursing care, with accurate guidelines helping with the removal of collecting bags among children under 3.
