Insights
Urine collection bag removal causes pain in young children. An oleo-calcareous liniment did not reduce this pain during urine specimen collection in pediatric patients.
Area of Science:
- Pediatric Emergency Medicine
- Pain Management
- Urology
Background:
- Urine collection bags are commonly used for pediatric urine specimen collection.
- Guidelines often recommend collection bags for UTI screening due to perceived ease and reduced pain.
- Clinical experience suggests bag removal can be a painful procedure for young children.
Purpose of the Study:
- To evaluate if an oleo-calcareous liniment reduces acute pain during urine collection bag removal in pre-continent children.
- To investigate a potential non-pharmacological intervention for pain associated with urine sample collection.
Main Methods:
- Prospective, randomized, controlled, single-blind study in pediatric emergency departments.
- Included pre-continent children aged 0-36 months requiring urine testing.
- Pain during bag removal was assessed using the FLACC scale, with video recording and blinded evaluators.
Main Results:
- 135 children were analyzed (70 intervention, 65 control).
- No significant difference in median FLACC pain scores between the liniment group (4.0) and control group (4.0).
- Moderate to severe pain (FLACC ≥4) was observed in 56% of patients.
Conclusions:
- Urine collection bag removal induces moderate to severe pain in approximately half of young children.
- Oleo-calcareous liniment application did not effectively reduce pain associated with urine collection bag removal.
- Alternative methods for less painful urine specimen collection in pediatrics may be warranted.
Background:
In pre-continent children, collection bags are frequently used as a first-line option to obtain a urine specimen. This practice, acknowledged by several guidelines for the step of UTI screening, is driven by a perception of the technique as being more convenient and less painful. However, our own experience led us to consider bag removal as a painful experience.
Objective:
Our aim was to determine whether the use of an oleo-calcareous liniment to aid bag removal reduced the acute pain expressed by young children.
Methods:
This prospective, randomized, controlled, single blind study was carried out in two emergency pediatrics departments. Pre-continent children aged 0-36 months admitted with an indication for urine testing were eligible for the study. Urine for dipstick test screening was obtained using a collection bag. At micturition, the patients were randomized into bag removal with (intervention group) or without (control group) liniment. Bag removal was recorded on video in such a manner as to permit independent assessments of pain by two evaluators blinded to group allocation. Pain was assessed using the FLACC scale.
Findings:
135 patients were analyzed: 70 in the intervention group and 65 in the control group. The median FLACC scores [interquartile range] for the intervention and control groups, respectively 4.0 [2.0-7.0] and 4.0 [3.0-7.0], did not differ significantly (p = 0.5). A FLACC score ≥4 was obtained for 56% of the patients and a score ≥7 for 28%.
Conclusion:
Removal of urine collection bags caused moderate to severe pain in half of the children included. The use of an oleo-calcareous liniment did not reduce this induced pain.
