Background Venous cannulation is among the most stressful and painful experiences of children hospitalization. Children with thalassemia need regular blood transfusion which needs venous access each time. The quality of care and quality of life of children will be improved if appropriate methods are used to reduce pain. This study aimed to compare vapocoolant spray and music in the reduction of pain of Venous cannulation in children with thalassemia. Methods The study was a randomized controlled clinical trial with a cross-over design. Thirty-six children with thalassemia from Thalassemia Patients of Pasteur Hospital in Bam from October to December 2020 and were recruited and randomly allocated to two arms. The pain of venous cannulation (no treatment) was measured in the first blood transfusion session as control. In the second and third sessions, two arms received music and vapocoolant spray before the venous cannulation with a cross-over design. The intensity of pain was measured by a Visual Analogue Scale (VAS). The change in pain scores was tested by ANOVA and Tukey post-hoc test between three measurements. Results During and after the cannulation, the pain was significantly lower in the vapocoolant measurement than in control and music (p < 0.05). There was a significant effect of vapocoolant spray during the procedure F (2, 90) = 25.604, p = 0.001. Also, there was a significant effect of vapocoolant spray after the procedure F (2, 90) = 10.087, p = 0.004). Music did not reduce the pain during cannulation (p = 0.413) and after that (p = 0.807) significantly when compared with control. Conclusions Vapocoolant was an effective method of pain reduction in the reduction of venous cannulation pain. Music was not effective in the reduction of venous cannulation pain when we compared it with controls. The pain of venous cannulation is rated as high and it can have negative effects on the children. There is a need to do more research on the methods of pain reduction of venous cannulation.

Background Lifelong provision of care to chronically ill patients increase the risk of physical and mental diseases in informal caregivers and adversely affects their quality of life. The present study examined the correlation between caregiver burden, depression, and quality of life among the informal caregivers of thalassemia and hemodialysis patients during the COVID-19 pandemic in southeastern Iran. Methods This cross-sectional correlational study used convenience sampling to select 200 informal caregivers involved in providing direct care for patients undergoing hemodialysis (n = 70) and patients with thalassemia (130) for at least 6 months. A demographic questionnaire, Beck’s Depression Inventory (BDI), the Quality-Of-Life Questionnaire (SF-36), and the Zarit Burden Interview were used to collect data in 2021. The data were analyzed with SPSS software (version 19) using frequency, percentage, independent samples t-test, ANOVA, and multivariate regression analysis. Results Most of the informal caregivers of the thalassemia and hemodialysis patients (58% and 43%) reported moderate levels of caregiver burden. There were significant correlations between the caregiver burden and depression (P < 0.0001) and between the caregiver burden and the quality of life (P < 0.009). The level of depression in informal caregivers of patients undergoing hemodialysis was higher than that of the informal caregivers of patients with thalassemia, but the quality of life in the informal caregivers of the patient’s undergoing hemodialysis was higher than that of the informal caregivers of the patients with thalassemia. Conclusion Considering the significant correlations between caregiver burden, depression, and quality of life in this study, healthcare providers are recommended to develop educational and supportive interventions to meet informal caregivers’ needs, mitigate their emotional distress, fears, and concerns, and prevent caregiver burden in times of greater uncertainty.
