Does formal hypnosis improve recovery from surgery in coronary bypass patients?
In coronary bypass patients, baseline hypnotizability is a significant predictor of postoperative ICU recovery and blood pressure stability, independent of formal hypnosis treatment.
p-value: p=<0.05
We studied 32 coronary bypass patients to examine the effect of hypnosis on recovery from surgery. The patients were assessed for hypnotizability with the Hypnotic Induction Profile (HIP) and assigned to experimental groups with a random stratification procedure to equate for differences in hypnotizability, age, and severity of illness. We taught patients in groups one and two formal hypnosis with different treatment strategies; patients in group three were not taught formal hypnosis or a treatment strategy. Scores on the HIP were significant predictors of recovery, independent of experimental treatment with formal hypnosis. Patients who scored "Midrange" stabilized more quickly in the intensive care unit (ICU) than those who scored "High" or "Low" (p = < .05). Patients who scored "High" had more labile blood pressure in the ICU compared to the "Midrange" and "Lows" (p = < .05). Measured hypnotizability was associated with the recovery sequence from surgery.
Greenleaf et al. (1992) conducted an RCT in Coronary bypass (n=32). Formal hypnosis vs. No formal hypnosis was evaluated on Recovery from surgery (stabilization in ICU and blood pressure lability) (p=<0.05). Measured hypnotizability, independent of formal hypnosis treatment, predicted recovery sequence, with midrange scores stabilizing more quickly in the ICU than high or low scores (p < 0.05).
