Effect of Classical Music on Depth of Sedation and Induction Propofol Requirements in Dogs

The main objective of this prospective, randomized, blind, cross-over experimental study was to evaluate the effect classical music on depth sedation and propofol requirements for induction anaesthesia in dogs. Twenty dogs were involved, each subjected three different treatments with a 3-month gap: Chopin music, Mozart no via loudspeakers. premedicated acepromazine butorphanol by intramuscular injection, induced using intravenously. To compare among treatments, we utilized non-parametric tests (Kruskal–Wallis test) due slight deviation from normal distribution parametric (ANOVA) requirements. When exposed (Chopin or Mozart), exhibited deeper required less their intubation compared no-music treatment (p < 0.05). Exposure had positive impact level sedation, more profound central nervous system depression seemed contribute approximately 20% lower dose tracheal intubation. Therefore, during preoperative period appeared exert beneficial effect, at least when applying specific pre-anaesthetic medications used present study.
