Clinical Trial Summary

This study will measure the efficacy of hypnosis on pain after a major abdominal surgery. The aim is to further improve comfort and rehabilitation of patients after surgery, beyond the usual early recovery after surgery (ERAS) enhancement protocols. Patients will be randomised (1:2) to the standard of care regarding pain management and rehabilitation, as part of the ERAS protocol, vs. ERAS + an additional hypnosis intervention. In this group, hospitalised patients are given 3 hypnosis sessions targeting analgesia between postoperative day 1 to 12. The study will collect outcomes about pain and its burden, sleep quality, appetite, mobilisation and mood. Secondary outcomes also include use of pain medication and length of hospital stay.

Description:

The primary objective of the present study is to evaluate the efficacy of hypnosis as an adjunct to the standard of care pain management program on postoperative pain compared to the standard ERAS program. Our hypothesis is that hypnosis, as part of a multi-modal analgesic management plan, will lead to decreased levels of pain compared to standard of care. A secondary hypothesis is that better controlled pain will lead to enhanced recovery, in terms of post-operative incidence of complications, physical comfort and independence, psychological and emotional state and length of stay. This study is an open label randomized controlled trial with two arms, comparing hypnosis as adjunctive therapy vs. standard of care. It is a monocentric study and will take place at Centre Hospitalier Universitaire Vaudois (CHUV), a teaching hospital in Lausanne, Switzerland. It represents a collaboration between the Service of Visceral Surgery and the Center of Integrative and Complementary Medicine. Participants will be recruited before a planned surgery, as well as in the post-surgical setting. They will be screened by the study team to ensure they fulfil the inclusion criteria. If eligible and after informed consent is obtained, an assessment of the cognitive function will be performed (cf. Chapter 4: study population). All included participants will then be randomized in a 2:1 proportion to the "Hypnosis (H)" group or the "Standard of Care (SOC)" group. After major abdominal surgery, all participants will benefit from a standard ERAS recovery program. The ERAS protocol involves multimodal pain management with medications, interventional pain therapy as needed, and psychological support if needed. Relevance: Acute pain has a major impact on LOS after surgery due to delayed recovery and opioid side effects. Furthermore, acute pain represents a risk for chronic pain, with its massive impact on quality of life and function. Interest is growing for non-pharmacological interventions as part of a multimodal approach for acute pain management. Hypnosis could be a low risk, cost-effective complementary therapy to improve patients' pain management, with possible impact on recovery and eventually a reduction of the length of hospital stay after surgery. If hypnosis is demonstrated to be an effective way to improve post-operative pain management in fragile patients undergoing massive abdominal surgery, then this therapy could be offered more broadly as adjunction to the actual standard of care in our teaching hospital. Furthermore, the Department of Visceral Surgery at CHUV is a teaching ward, accredited by the ERAS society. Therefore, results may be used to improve patient care within the ERAS society more broadly.
