Efficacy of hypnosis in adults undergoing surgery or medical procedures: a meta-analysis of randomized controlled trials

Clinical Psychology Review
S TefikowJ Rosendahl


This meta-analysis investigates the efficacy of hypnosis in adults undergoing surgical or medical procedures compared to standard care alone or an attention control. Through a comprehensive literature search N=34 eligible randomized controlled trials (RCTs) were included, comprising a total of 2597 patients. Random effects meta-analyses revealed positive treatment effects on emotional distress (g=0.53, CI 95% [0.37; 0.69]), pain (g=0.44, CI 95% [0.26; 0.61]), medication consumption (g=0.38, CI 95% [0.20; 0.56]), physiological parameters (g=0.10, CI 95% [0.02; 0.18]), recovery (g=0.25, CI 95% [0.04; 0.46]), and surgical procedure time (g=0.25, CI 95% [0.12; 0.38]). In conclusion, benefits of hypnosis on various surgically relevant outcomes were demonstrated. However, the internal validity of RCTs seems limited and further high methodological quality RCTs are needed to strengthen the promising evidence of hypnosis for adults undergoing surgery or medical procedures.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
