Audiovisual interventions to reduce the use of general anaesthesia with paediatric patients during radiation therapy
Insights
Audiovisual interventions helped young children undergoing radiation therapy stay still and reduce anxiety. This method significantly decreased the need for general anesthesia in pediatric patients during treatment.
Area of Science:
- Pediatric Oncology
- Medical Technology
- Child Psychology
Background:
- Radiation therapy for children often requires general anesthesia due to immobility and anxiety.
- Distraction techniques are explored to improve pediatric patient cooperation during medical procedures.
Purpose of the Study:
- To evaluate the effectiveness of clinical audiovisual interventions in reducing the need for general anesthesia in pediatric radiation therapy patients.
- To assess the utility of distraction interventions for improving immobilization and reducing separation anxiety in children aged 2-6 years.
Main Methods:
- A retrospective audit and case study review of children aged 2-6 years undergoing radiation therapy.
- Implementation of a simple, inexpensive audiovisual system with options for viewing carers, watching DVDs, or listening to carers via microphone.
- Analysis of participation in audiovisual interventions and the subsequent requirement for general anesthesia.
Main Results:
- Out of 37 pediatric patients (2-6 years) receiving radiation therapy, 24 participated in audiovisual interventions.
- 92% (22 out of 24) of participating children did not require general anesthesia for some or all of their treatment.
- Case studies highlighted the system's utility and limitations in providing supportive care.
Conclusions:
- Clinical audiovisual interventions are a viable supportive care strategy for pediatric radiation therapy.
- These interventions can significantly reduce the reliance on general anesthesia for young children during radiation treatment.
- The study suggests that distraction through audiovisual means improves patient management and reduces treatment-related distress.
Abstract:
Clinical audiovisual interventions were implemented to avoid the use of general anaesthesia with children undergoing radiation therapy treatment. A retrospective audit and case study review was conducted to evaluate the utility of distraction interventions aimed at improving immobilisation and reducing separation anxiety for children aged between 2 and 6 years old who received radiation therapy. A simple, inexpensive audiovisual system was established using commercially available equipment. Paediatric patients could elect to (i) use a closed-circuit TV system that allowed them to see their carer(s); (ii) watch a DVD movie; or (iii) listen to carer(s) on a microphone during their treatment. Over a 2-year period (March 2007-May 2009), 37 paediatric patients aged 2-6 years received radiation therapy at the centre. Twenty-four children participated in audiovisual interventions, and 92% (n = 22) of these children did not require the use of general anaesthesia for some or all of their treatment. Case study review illustrates the utility and limitations of the system. The audit and case studies suggest that the audiovisual interventions provided supportive care and reduced the need to anaesthetise children undergoing radiation therapy treatment.
