A randomized, double blinded, placebo controlled study with 335 surgery patients at UC Davis (completed at Hershey College of Medicine at Penn. State) randomly assigned one of five audio interventions to pre-surgery patients undergoing lengthy surgeries. The tapes included Affirmations, Hemi-Sync, Didactic Explanation, Guided Imagery and a control tape of whooshing sounds. Outcomes revealed that most of the interventions significantly reduced anxiety; but only the guided imagery significantly reduced length of stay and blood loss. The Hemi-Sync tape actually increased blood loss.
