“…For example, providing positive information has been found to decrease postoperative nausea following gynaecologic surgery [51] and to protect against seasickness in navel cadets [52]. However, as we have argued previously [10] there are two reasons why expectancybased interventions may be more difficult to implement in cancer patients.…”

“…[23][24][25] Changes in objectively measured outcomes, including reduction in blood loss during surgery 26 and resumption of normal gastrointestinal activity in the postoperative period, 27 have also been observed. A particularly interesting example of how response expectancies affect chemotherapy-related nausea comes from a large multicenter study conducted by our research group examining the efficacy of acustimulation and acupressure bands as an adjunct to standard antiemetics for nausea control.…”

Several studies have shown that patients' expectancy for the development of nausea following chemotherapy are robust predictors of that treatment-related side effect and some studies have shown that interventions designed to influence expectancies can affect patients' reports of symptoms. In this randomized multicenter Community Clinical Oncology Program (CCOP) trial, we investigated the effect of an expectancy manipulation designed to reduce nausea expectancy on chemotherapy-induced nausea in 358 patients scheduled to receive chemotherapy treatment. Patients in the intervention arm received general cancer-related educational material plus specific information about the efficacy of ondansetron specifically designed to diminish nausea expectancy. Patients in the control arm received only the general cancer-related educational material. Nausea expectancy was assessed both prior to and following the educational intervention. We observed a significant reduction in nausea expectancy in the intervention group (p = 0.024) as compared to the control group (p = 0.34). In the intervention group, patients' expectations of nausea assessed prior to the intervention correlated significantly with average nausea (r = .27, p = .001); whereas nausea expectancy assessed following the intervention did not (r = 0.1, p = 0.22). In our study, the expectancy manipulation reduced patients' reported expectations for the development of nausea but did not reduce occurrence of nausea. Furthermore, post-intervention nausea expectancy compared to pre-intervention expectancy was less predictive of subsequent nausea. Explanations for these findings include the possibility that the expectancy manipulation was not strong enough, and the possibility that changing nausea expectancies does not change occurrence of nausea.

“…In our study, only 2 patients required pharmacological therapy for PONV. Previous studies have shown that hypnosis is effective for prevention of nausea and vomiting [1,2,18,19]. All 15 patients in our study also had smooth postoperative course and reported complete amnesia for intra-operative events.…”

Background: Surgery is associated with significant anxiety and stress in a majority of patients. Most medications used to achieve anxiolysis and sedation are limited by their side effects. 'Non-pharmacological hypnosis' is defined as a subjective state, during which alterations of perception and memory can be elicited by suggestions. Methods: In this prospective, observational study, hypnosis was used in fifteen patients for a range of surgeries; as a complementary technique to achieve sedation, establishment of intravenous (IV) access, and to decrease the anesthetic dose and postoperative nausea, vomiting. Results: Hypnosis successfully reduced the anxiety from a range of 45 to 90 (median of 60) to a range of 1 to 20 (median of 10). When calculated and analysed as means, the mean decrease was 56 (95% CI: 51.81, 60.04) with a p<0.001. Twelve out of fifteen patients had their intravenous access established under hypno-analgesia with no memory of that event. Thirteen patients had successful prevention of nausea, vomiting without antiemetics. Hypnosis also decreased the dose of induction agent in all patients having general anesthesia. Conclusion: Increasing knowledge and sophistication in anaesthesiology has given a wide spectrum of anesthetic agents and equipments to choose. However, achievement of sedation, anxiolysis and IV access are still areas of challenge which need more human interaction rather than administration of a miracle agent. We aim to demonstrate that hypnosis is well suited for such a purpose and should be utilised, at least in suitable patients.
