Researchers from WellStar Health System in Atlanta GA and Kennesaw State University in Kennesaw, GA assessed the usefulness of guided imagery in helping wean patients off mechanical ventilators.

Forty-two patients were selected from two community acute care hospitals. One hospital served as the comparison group and provided routine care (no intervention) while the other hospital provided the guided imagery intervention.

Sedation levels, sedative and analgesic volume consumption, and physiological responses were the outcomes that were measured and compared.

Researchers from Cyprus University of Technology and the University of Athens conducted a randomized, controlled study, testing the effectiveness of guided imagery and progressive muscle relaxation as stress reducing interventions in 236 patients with prostate and breast cancer who were being treated with chemotherapy.

Subjects were randomly assigned to either the control group or the intervention group (PMR and GI), and were observed for a total duration of 3 weeks. In total, 104 were randomized to the control group and 104 to the intervention group.

Researchers from Pusan National University in Korea used a pre- and post-test consecutive experimental design to evaluate the effects of guided imagery on stress and fatigue in patients undergoing radioactive iodine therapy following a thyroidectomy.

Eighty-four subjects with thyroid cancer were assigned to either an experimental group (n=44) which received 4 weeks of guided imagery once a day or a treatment as usual group (n=40).

In a small pilot study at the Pediatric Pulmonary Department of Armand Trousseau Hospital in Paris, France, investigators assessed the efficacy of medical hypnosis to reduce anticipatory anxiety and acclimatization time in children who are candidates for long-term ventilator use or NPPV (noninvasive positive pressure ventilation).

The hypnosis was performed by a trained nurse, and acclimatization time and long-term compliance with NPPV were evaluated.

Hypnosis was performed in nine children aged 2 to 15 years. Seven children had a high level of anticipatory anxiety because of a tracheotomy since birth (n=2), a history of maxillofacial surgery (n=2), severe dyspnea because of lung disease (n=2), and morbid obesity and depression (n=1), and two children with obstructive sleep apnea failed standard NPPV initiation.

Investigators from Soroka University Medical Center in Beer-Sheva, Israel, investigated whether hypnosis during embryo transfer contributes to successful fertility outcomes.
 
In this case-control, clinical study with infertile couples undergoing in vitro fertilization (IVF), 98 IVF/ET cycles with hypnosis were matched with 96 regular IVF/ET cycles. Rates of clinical pregnancy and implantation were then compared between the two groups.

There were 52 clinical pregnancies out of 98 cycles (53.1%), with an implantation rate of 28% among hypnosis IVF/ET cycles, as compared with 29 out of 96 (30.2%) clinical pregnancies and an implantation rate of 14.4% in the control cycles.

Investigators from the Clinique du Mail in La Rochelle, France, conducted a randomized, prospective, controlled study, comparing the efficacy of hypnosis on patients receiving embryo transfer, to measure impact on pregnancy rates and degree of anxiety, as compared to the efficacy of Diazepam (Valium).
 
Previous research by Levitas et al (2006) showed in a cohort study that hypnosis during embryo transfer (ET) increased the pregnancy ratio by 76%.
 
In order to evaluate hypnosis during ET in a general population, the authors compared the impact of diazepam (usual premedication) administered before ET plus muscle relaxation, versus hypnosis plus placebo, in 94 patients.

Investigators from the Continuum Cancer Centers of the New York Beth Israel Medical Center evaluated the impact of guided imagery on patients undergoing radiation therapy for breast cancer.

Eligible patients receiving guided imagery sessions were monitored via biofeedback before and after each session. Measures included blood pressure, respiration rate, pulse rate, and skin temperature.
 
In addition, the EuroQoL Group's EQ-5D health questionnaire was used for subjective assessment and patient feedback was collected at the end of radiation therapy through a satisfaction survey.

Measured parameters revealed statistically significant improvement from baseline, with decreases noted in respiration rate and pulse rate as well as systolic and diastolic blood pressure. Skin temperature increased, indicating more peripheral capillary flow as a result of a decrease in the sympathetic response.

Researchers from the Continuum Cancer Center at Beth Israel Medical Center in New York evaluated the impact of guided imagery on patients undergoing radiation therapy for breast cancer.

Eligible patients receiving guided imagery sessions were monitored via biofeedback before and after each session. Monitored measures included blood pressure, respiration rate, pulse rate, and skin temperature.

In addition, the EuroQoL Group's EQ-5D questionnaire was used for subjective assessment; and patient feedback was collected at the end of radiation therapy through a satisfaction survey.

Researchers from the Department of Surgery at Columbia University in New York examined whether guided imagery could reduce depression and therefore post-op cardiac events and even deaths (associated with depression) in patients who’d undergone coronary artery bypass graft (CABG) surgery.

Traci Stein and her team hypothesized that this low cost and easy-to-implement technique could reduce post-op distress in CABG patients.  Fifty-six patients were randomized into 3 groups: guided imagery, music therapy, and standard care control.
 
Patients in the imagery and music groups listened to Health Journeys audiotapes preoperatively and intraoperatively.  All patients completed psychological, complementary medicine therapies use, and other assessments preoperatively and at 1 week and 6 months postoperatively.

Researchers from Université Laval in Quebec, Canada, assessed the benefits of mind-body interventions during pregnancy in preventing or treating women's anxiety and in influencing perinatal outcomes.

They searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 November 2010), MEDLINE (1950 to 30 November 2010), EMBASE (1974 to 30 November 2010), the National Center for Complementary and Alternative Medicine (NCCAM) (1 December 2010), ClinicalTrials.gov (December 2010) and Current Controlled Trials (1 December 2010), as well as searching the reference lists of selected studies and contacting professionals and authors in the field.
