Effects of guided imagery on blood pressure in pregnant women with hypertension: a pilot randomized controlled trial

Effect of Guided Imagery on Patient Comfort, Vital Signs, Pain, Anxiety, and Satisfaction in Cancer Patients Undergoing Port Catheterization With Local Anesthesia: A Prospective Randomized Controlled Study

BACKGROUND

Port catheter placement is usually an operation performed under local anesthesia. Being conscious during the interventions performed with local anesthesia can lead to anxiety and stress.

OBJECTIVE

The aim of this study was to determine the effect of guided imagery performed before and during the procedure on vital signs and comfort, pain, anxiety, and satisfaction levels in patients with cancer undergoing port catheterization with local anesthesia.

METHODS

A total of 80 patients were included in the study. Patients in the intervention group received standard treatment and nursing care, as well as a guided imagery intervention once before and once during the procedure. Patients in the control group received only standard treatment and nursing care.

RESULTS

Patients in the guided imagery group reported lower pain and anxiety scores, higher patient satisfaction, and increased comfort compared with patients in the control group. Patients in the guided imagery group showed significantly lower respiratory rate and heart rate than the control group by the end of the procedure. There was no significant difference in blood pressure.

CONCLUSION

Practicing guided imagery before and during a procedure performed under local anesthesia reduced cancer patients' pain, increased patient satisfaction and comfort, and had a positive effect on their respiratory and heart rates.

IMPLICATIONS FOR PRACTICE

We recommend guided imagery as a practical, low-cost complementary therapy for patients receiving local anesthesia.

The effect of nonpharmacological interventions on the mental health of high-risk pregnant women: A systematic review

OBJECTIVES

To evaluate the effect of nonpharmacological interventions on the mental health of high-risk pregnant women.

METHODS

This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 (PRISMA) statement. The Cochrane Library, Embase, CINAHL, PubMed and Web of Science databases were systematically searched for randomized controlled trials and quasi-randomized controlled trials from inception to April 2021. The quality of the studies was assessed using the Cochrane Risk of Bias Tool 2.0. Data were independently extracted and narratively synthesized.

RESULTS

Fifteen studies involving 1723 pregnant women were selected. Nonpharmacological interventions included cognitive behavioral interventions, yoga, relaxation interventions, psychological and educational support interventions, and acupressure. Cognitive behavioral interventions and yoga for high-risk pregnant women had potential benefits on the symptoms of anxiety, stress and depression. There was insufficient evidence that relaxation interventions, psychological and educational support interventions and acupressure had positive effects on these women's mental health.

CONCLUSIONS

This review showed that cognitive behavioral interventions and yoga during pregnancy may benefit women with high-risk pregnancies. However, due to methodological limitations of this review, further studies with robust methodological designs are needed to verify the efficacy.

Mind-Body Techniques in Pregnancy and Postpartum

Maternal stress can perturb physiology and psychiatric health leading to adverse outcomes. This review investigates the effectiveness of several mind-body therapies-namely biofeedback, progressive muscle relaxation, guided imagery, tai chi, and yoga-as interventions in reducing maternal stress and other pregnancy-related conditions. Through randomized trials, these techniques have shown promising benefits for reducing pain, high blood pressure, stress, anxiety, depressive symptoms, labor pain and outcomes, and postpartum mood disturbances. As these interventions are easy to implement, low cost, and safe to perform in pregnancy, they should be considered as alternative, nonpharmaceutical interventions to use during pregnancy and postpartum care.

The effect of guided imagery and reflexology on pain intensity, duration of labor and birth satisfaction in primiparas: randomized controlled trial

The aim of the researchers is to determine the effects of guided imagery and foot reflexology on pain intensity, duration of labor, and birth satisfaction. While cervical dilation was 4 cm, the guided imagery group has watched the guided imagery video; the reflexology group has received reflexology for both feet for 30 min. The mean VAS scores of the experimental groups were statistically lower than the mean score of the control group. The difference between the time averages of the groups was found to be significant. Birth satisfaction meanscores of the experimental groups was found to be higher than the control group.

The safety and effectiveness of mind body interventions for women with pregnancy induced hypertension and or preeclampsia: A systematic review and meta-analysis

OBJECTIVES

To undertake a systematic review of the safety and effectiveness of mind body approaches for women with hypertensive disorders in pregnancy (HDP).

DESIGN

A search was undertaken of databases from inception to 2019 for randomised and quasi randomised controlled trials.

MAIN OUTCOME MEASURES

The primary outcome was a reduction in systolic and / or diastolic blood pressure for women with hypertension and or preeclampsia in pregnancy.

RESULTS

121 studies were identified and eight studies were included in this review. These included mind body interventions examining yoga, guided imagery, relaxation, music, and acupuncture for HDP. Two studies of relaxation found a reduction in systolic (MD -11.3, 95%CI -13.23 to -9.39) and diastolic blood pressure (MD -6.59, 95%CI -9.43 to -3.75) and reduced stress (MD -11.4, 95%CI -16.5 to -6.3). In one study of yoga, the risk of developing HDP was reduced (RR 0.28, 95% CI 0.09 to 0.91, 59 women) and a second study found a reduction in stress at the end of the intervention of yoga. One trial of guided imagery found a reduction in mean arterial blood pressure compared to the control (4.35, 95% -8.04 to -0.66, p=0.02). Overall there was no effect on the development of preeclampsia, use of anti-hypertensive medication and any neonatal outcomes from the interventions evaluated. Few trials reported on safety outcomes, one trial of acupuncture reported one case of placental abruption and three cases of acupuncture related side effects.

CONCLUSION

Few high quality trials have examined the effectiveness and safety of mind body interventions to manage HDP. Relaxation, yoga, guided imagery and music may have some potential benefit. Safety issues are completely unclear and thus the risk-benefit ratio of all interventions could not be determined. Further research is recommended.

Guided imagery for treating hypertension in pregnancy

BACKGROUND

Hypertension (high blood pressure) in pregnancy carries a high risk of maternal morbidity and mortality. Although antihypertensive drugs are commonly used, they have adverse effects on mothers and fetuses. Guided imagery is a non-pharmacological technique that has the potential to lower blood pressure among pregnant women with hypertension. Guided imagery is a mind-body therapy that involves the visualisation of various mental images to facilitate relaxation and reduction in blood pressure.

OBJECTIVES

To determine the effect of guided imagery as a non-pharmacological treatment of hypertension in pregnancy and its influence on perinatal outcomes.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register, and two trials registers (October 2018). We also searched relevant conference proceedings and journals, and scanned the reference lists of retrieved studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs). We would have included RCTs using a cluster-randomised design, but none were identified. We excluded quasi-RCTs and cross-over trials.We sought intervention studies of various guided imagery techniques performed during pregnancy in comparison with no intervention or other non-pharmacological treatments for hypertension (e.g. quiet rest, music therapy, aromatherapy, relaxation therapy, acupuncture, acupressure, massage, device-guided slow breathing, hypnosis, physical exercise, and yoga).

DATA COLLECTION AND ANALYSIS

Three review authors independently assessed the trials for inclusion, extracted data, and assessed risk of bias for the included studies. We checked extracted data for accuracy, and resolved differences in assessments by discussion. We assessed the certainty of the evidence using the GRADE approach.

MAIN RESULTS

We included two small trials (involving a total of 99 pregnant women) that compared guided imagery with quiet rest. The trials were conducted in Canada and the USA. We assessed both trials as at high risk of performance bias, and low risk of attrition bias; one trial was at low risk for selection, detection, and reporting bias, while the other was at unclear risk for the same domains.We could not perform a meta-analysis because the two included studies reported different outcomes, and the frequency of the intervention was slightly different between the two studies. One study performed guided imagery for 15 minutes at least twice daily for four weeks, or until the baby was born (whichever came first). In the other study, the intervention included guided imagery, self-monitoring of blood pressure, and thermal biofeedback-assisted relaxation training for four total hours; the participants were instructed to practice the procedures twice daily and complete at least three relief relaxation breaks each day. The control groups were similar - one was quiet rest, and the other was quiet rest as bed rest.None of our primary outcomes were reported in the included trials: severe hypertension (either systolic blood pressure of 160 mmHg or higher, or diastolic blood pressure of 110 mmHg or higher); severe pre-eclampsia, or perinatal death (stillbirths plus deaths in the first week of life). Only one of the secondary outcomes was measured.Low-certainty evidence from one trial (69 women) suggests that guided imagery may make little or no difference in the use of antihypertensive drugs (risk ratio 1.27, 95% confidence interval 0.72 to 2.22).

AUTHORS' CONCLUSIONS

There is insufficient evidence to inform practice about the use of guided imagery for hypertension in pregnancy.The available evidence for this review topic is sparse, and the effect of guided imagery for treating hypertension during pregnancy (compared with quiet rest) remains unclear. There was low-certainty evidence that guided imagery made little or no difference to the use of antihypertensive drugs, downgraded because of imprecision.The two included trials did not report on any of the primary outcomes of this review. We did not identify any trials comparing guided imagery with no intervention, or with another non-pharmacological method for hypertension.Large and well-designed RCTs are needed to identify the effects of guided imagery on hypertension during pregnancy and on other relevant outcomes associated with short-term and long-term maternal and neonatal health. Trials could also consider utilisation and costs of health service.

Relaxation Interventions for Antepartum Mothers on Hospitalized Bedrest

Women with a high-risk pregnancy on hospitalized bedrest engaged in relaxation interventions, including guided imagery, visual imagery, and listening to music. Qualitative interviews gathered their perspectives on the effects of hospitalized bedrest on well-being and the subjective experiences related to the relaxation interventions. Benefits identified included improved physical well-being and sleep. Such relaxation interventions were concluded to have the potential to positively influence the occupational well-being of this population, resulting in more positive outcomes for mothers.

Guided Imagery and Stress in Pregnant Adolescents

OBJECTIVE

We examined the effects of a guided imagery intervention on perceived stress in pregnant adolescents.

METHOD

Thirty-five pregnant adolescents recruited from a local alternative education program participated in a guided imagery intervention. Participants listened to a pregnancy-specific guided imagery recording on four separate occasions during their pregnancies. Perceived stress was measured immediately before and after each session using the Perceived Stress Measure-9 (PSM-9).

RESULTS

Participants' pre- and postsession PSM-9 scores for three of the four sessions demonstrated a significant reduction in stress. Participants' baseline stress levels also decreased significantly across the four listening sessions. The greatest reductions in stress within and between sessions occurred in the early sessions, with effects diminishing over time.

CONCLUSION

Pregnant teens experienced initial short- and long-term stress reduction during a guided imagery intervention, supporting the use of guided imagery to reduce stress in pregnant adolescents.

Meditative therapies for reducing anxiety: a systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Anxiety disorders are among the most common psychiatric disorders and meditative therapies are frequently sought by patients with anxiety as a complementary therapy. Although multiple reviews exist on the general health benefits of meditation, no review has focused on the efficacy of meditation for anxiety specifically.

METHODS

Major medical databases were searched thoroughly with keywords related to various types of meditation and anxiety. Over 1,000 abstracts were screened, and 200+ full articles were reviewed. Only randomized controlled trials (RCTs) were included. The Boutron (Boutron et al., 2005: J Clin Epidemiol 58:1233-1240) checklist to evaluate a report of a nonpharmaceutical trial (CLEAR-NPT) was used to assess study quality; 90% of the authors were contacted for additional information. Review Manager 5 was used for meta-analysis.

RESULTS

A total of 36 RCTs were included in the meta-analysis (2,466 observations). Most RCTs were conducted among patients with anxiety as a secondary concern. The study quality ranged from 0.3 to 1.0 on the 0.0-1.0 scale (mean = 0.72). Standardized mean difference (SMD) was -0.52 in comparison with waiting-list control (p < .001; 25 RCTs), -0.59 in comparison with attention control (p < .001; seven RCTs), and -0.27 in comparison with alternative treatments (p < .01; 10 RCTs). Twenty-five studies reported statistically superior outcomes in the meditation group compared to control. No adverse effects were reported.

CONCLUSIONS

This review demonstrates some efficacy of meditative therapies in reducing anxiety symptoms, which has important clinical implications for applying meditative techniques in treating anxiety. However, most studies measured only improvement in anxiety symptoms, but not anxiety disorders as clinically diagnosed.

A randomized control trial: the effect of guided imagery with tape and perceived happy memory on chronic tension type headache

PURPOSE

To determine the effects of guided imagery techniques with tape and perceived happy memory on people with chronic tension-type headache (CTTH).

METHODS

Sixty people with CTTH completed the demographic questionnaire and headache diary 1 week before the treatment, that is, for 3 weeks during the treatment and 1 week immediately after that. The people were randomly assigned into one of three different treatment groups: a Guided imagery (GI) with tape group (n = 20), a GI with perceived happy memory group (n = 20) and a control group (n = 20). In addition to individualized headache therapy, subjects listened to a guided imagery audiocassette tape or imagined the happiest personal memory three times per week for 3 weeks. It should be noted that 20 control subjects received individualized therapy without guided imagery.

RESULTS

The guided imagery groups both tape and perceived happy memory had significantly more improvement than the controls in three of the outcome measures; headache intensity, headache frequency and headache duration. There were no other significant differences between the guided imagery groups (tape and perceived happy memory) at any time point.

CONCLUSIONS

Guided imagery is an effective, available and affordable nonpharmacological therapy either with tape or with perceived happy memory for the management of the CTTH.

Global and cultural perinatal nursing research: improving clinical practice

High-quality perinatal nursing care should be based on the best evidence including research findings, clinical expertise, and the preferences of women and their families. Principles of perinatal research initiatives are defined, with suggested research priorities designed to close current gaps in the micro and macro environments of perinatal nursing throughout the world. Nearly a decade ago, the following question was asked, "Where is the 'E' (evidence) in maternal child health?" Improving the quality and safety of perinatal nursing care for culturally diverse women globally is the primary goal of nurse researchers leading the future of perinatal healthcare.
