Effect of an Intervention Using Voice Recording of a Family Member on Patients Undergoing Mechanical Ventilator Weaning Process

Abstract

Purpose: This study aimed to determine the impact of an intervention using voice recording of family members on pain, anxiety, and agitation in patients undergoing weaning from mechanical ventilation. Methods: A randomized control pre-post experimental design was implemented to 53 participants, with 27 and 26 participants in the experimental and control groups, respectively. A 70-second voice recording of a family member, repeated three times at 10-minute intervals was used as an intervention for the experimental group. Mean-while, participants in the control group used headset for 30 minutes. Structured instruments were utilized to measure pain, anxiety, agitation, and the weaning process. Wilcoxon Signed Ranks test and the Mann-Whitney U test, or χ2 test, were used for data analysis. Results: The experimental group exhibited significant decrease in pain (Z =-3.53, p < .001), anxiety (t = 5.45, p < .001), and agitation (Z =-2.99, p = .003) scores compared with those of the control group. However, there was no significant difference between groups in the weaning process’ simplification (χ2 = 0.63, p = .727). Conclusion: Intervention using family members’ voice recording effectively reduces pain, anx-iety, and agitation in patients undergoing weaning from mechanical ventilation. This can be actively utilized to provide a more comfort-able process for patients.
