Hypnosis Reducese Medication During Procedures

Lang, E. V., J. S. Joyce, D. Spiegel, D. Hamilton and K. K. Lee (1996). "Self-hypnotic relaxation during interventional radiological procedures: effects on pain perception and intravenous drug use." Int J Clin Exp Hypn 44(2): 106-19.
The authors evaluated whether self-hypnotic relaxation can reduce the need for intravenous conscious sedation during interventional radiological procedures. Sixteen patients were randomized to a test group, and 14 patients were randomized to a control group. All had patient-controlled analgesia. Test patients additionally had self-hypnotic relaxation and underwent a Hypnotic Induction Profile test. Compared to controls, test patients used less drugs (0.28 vs. 2.01 drug units; p < .01) and reported less pain (median pain rating 2 vs. 5 on a 0-10 scale; p < .01). Significantly more control patients exhibited oxygen desaturation and/or needed interruptions of their procedures for hemodynamic instability. Benefit did not correlate with hypnotizability. Self-hypnotic relaxation can reduce drug use and improve procedural safety.

Adjunct Hypnosis in Patients Undergoing Invasive Medical Procedures

OBJECTIVES: To assess the effects of age on responsiveness to self-hypnotic relaxation as an analgesic adjunct in patients undergoing invasive medical procedures. MATERIAL AND METHODS: Secondary data analysis from a prospective trial with 241 patients randomized to receive hypnosis, attention, and standard care treatment during interventional radiological procedures. Growth curve analyses, hierarchical linear regressions, and logistic regressions using orthogonal contrasts were used for analysis. Outcome measures were Hypnotic Induction Profile scores, self-reported pain and anxiety, medication use, oxygen desaturation < or =89%, and procedure time. RESULTS: Hypnotizability did not vary with age (p = .19). Patients receiving attention and hypnosis had greater pain reduction during the procedure (p = .02), with trends toward lower pain with hypnosis (p = .07); this did not differ by age. As age increased, patients experienced more rapid pain control with hypnosis (p = .03). There was more rapid anxiety reduction with attention and hypnosis (p = .03). Trends toward lower final anxiety were also observed with attention and hypnosis versus standard care (p = .08), and with hypnosis versus attention (p = .059); these relationships did not differ by age. Patients requested and received less medication and had less oxygen desaturation < or =89% with attention and hypnosis (p < .001); this did not differ by age. However, as age increased, oxygen desaturation was greater in standard care (p = .03). Procedure time was reduced in the attention and hypnosis groups (p = .007); this did not vary by age. CONCLUSIONS: Older patients are hypnotizable and increasing age does not appear to mitigate the usefulness of hypnotic analgesia during invasive medical procedures.
