Self-hypnotic relaxation during interventional radiological procedures: Effects on pain perception and intravenous drug use 46th Annual Meeting of the Society-for-Clinical-and-Experimental-Hypnosis Lang, E. V., Joyce, J. S., Spiegel, D., Hamilton, D., Lee, K. K. SAGE SCIENCE PRESS. 1996: 106–19

Abstract

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.
