Satisfaction and experiences of pregnant hypertensive women participating in a feasibility study of guided imagery effects on blood pressure

Introduction: Hypertensive disorders of pregnancy are associated with maternal and perinatal health risk. Some studies have demonstrated blood pressure reduction from the use of relaxation therapies, although previous study in pregnancy was limited. We undertook a RCT to determine the effects of guided imagery relaxation on BP and anxiety in hypertensive women during pregnancy, to answer feasibility questions for a larger trial. Objectives: This presentation will describe experiences and satisfaction with study participation, as reported by women in our study. Methods: Pregnant women with hypertension (n = 69) were randomized to two daily periods of guided imagery or quiet rest, for 4 weeks or until delivery, whichever came first. Participants provided compliance data and evaluated guided imagery each week, and completed postpartum questionnaires about their satisfaction with study participation. Results: Sixty women completed at least one week in the study. Compliance with allocated group conditions was high. Most women were satisfied with their allocation; 83.3% would choose to be in the study again. A greater proportion (42.4%) indicated that the study reassured them, compared to 3.4% who felt it added to their worry. Of those in the Guided Imagery group providing ratings, more than 75% reported enjoyment and ease of use. Most indicated they would use it for future hypertension in pregnancy and for stress, and would recommend it to others. Conclusion: Our results suggest that Guided Imagery may moderate BP increases in pregnant women with hypertension. However, success of any clinical intervention requires a high degree of patient compliance and acceptability. Guided imagery was acceptable, based on reported use and intent to use it for future stress and hypertension. Guided imagery can be used by hypertensive pregnant women to promote relaxation. Further research is required to determine whether it can improve physical and psychological health outcomes during pregnancy, birthing and postpartum.
