137 - Physiological Effects of Weighted Blanket Use in Adolescent Dental Patients

Abstract:

Purpose: The primary objective of this analytic cross-sectional study was to measure physiological changes experienced by the adolescent dental patient during routine restorative procedures when using a Wallaby weighted blanket. The secondary objective was to assess changes in patient satisfaction and perceived dental anxiety when using the blanket.



Methods: Eligible participants were neurotypical patients aged 12–16 with Class I or II lesions not near the pulp, who benefit from additional dental anxiety management tools. Only patients who opted to use nitrous oxide were considered for the study. All patients in the study utilized the weighted blanket with physiological and subjective data being obtained. Following consent and assent, a pre-procedural survey was completed to assess patient feelings towards upcoming dental procedures and the use of a weighted blanket during the procedure. The patient’s weight was measured to determine the appropriate blanket weight. After the patient was seated, pre-operative blood pressure was obtained. The weighted blanket was then placed on the patient, and 30-40% nitrous oxide at 5 liters/minute was administered for the duration of treatment. Five liters/minute of 100% oxygen was administered for 5 minutes after nitrous oxide use was no longer needed for treatment. Intraoperative blood pressure was taken every 5 minutes throughout restorative treatment. After treatment was completed, a postoperative blood pressure was recorded with the patient sitting up and without the blanket. Finally, a post-operative survey assessing blanket comfort, satisfaction, and efficacy of intervention was provided for the patient.



Results: Twenty-five patients were enrolled in this study. Blood pressure showed a significant decrease at 10 minutes (p=0.049) and 15 minutes (p=0.046). Pulse showed a significant decrease at 15 minutes (p=0.04). Mean arterial pressure showed a significant decrease at 5, 10, and 15 minutes (p=0.024, p=0.003,p=.016). Patients with low and moderate anxiety reported decreased anxiety at 100% and 94%. 96% of patients would like to use the weighted blanket for future appointments, and 88% reported the blanket helped during treatment.

Conclusion: Overall, patients had a positive experience with the weighted blanket. The weighted blanket was effective in decreasing patient anxiety.
