“…The assumed positive effect of music is mediated by activation of brain areas associated with rewards, as documented by functional magnetic resonance imaging ( Salimpoor et al, 2013 ). For veterinary patients, slow-tempo classical music appears to have a calming effect on kenneled dogs ( Wells, Graham & Hepper, 2002 ; Kogan, Schoenfeld-Tacher & Simon, 2012 ; Bowman et al, 2015 ), and in another study on anesthetized cats, it resulted in decreased blood pressure and heart rates when compared to other types of music ( Mira et al, 2016 ). However, the proposed intrinsic “deactivating” and calming effects of slow-tempo music on the emotional state ( Moris & Linos, 2013 ; Snowdon, Zimmermann & Altenmüller, 2015 ) in people may be affected by prior experience and exposure to the music ( Walker, 1996 ).…”

“…In contrast to the negative effects of noise, perioperative use of slow-tempo music has received attention as a source of anxiolysis and analgesia in human surgical patients ( Moris & Linos, 2013 ; Hole et al, 2015 ; Van der Heijden et al, 2015 ). Although the studies evaluating anxiolytic effects of music in veterinary patients are limited, the use of classical music has shown some potential in improving stress-related behaviors and physiologic parameters in both cats and dogs ( Bowman et al, 2015 ; Mira et al, 2016 ).…”

BackgroundPrevious studies in human patients suggest depth of sedation may be affected by environmental noise or music; however, related data in domestic animals is limited. The objective of the current study was to investigate the effect of noise and music on dexmedetomidine-induced (DM- 10 µg/kg, IM) sedation in 10 dogs.MethodsIn a crossover design, post-DM injection dogs were immediately subjected to recorded human voices at either 55–60 decibel (dB) (Noise 1) or 80–85 dB (Noise 2); classical music at 45–50 dB (Music); or background noise of 40–45 dB (Control+). Control− included IM saline injection and exposure to 40–45 dB background noise. Sedation was assessed via monitoring spontaneous behavior and accelerometry (delta-g) throughout three 20-min evaluation periods: baseline, noise exposure, and post-treatment. Sedation was further assessed during two restraint tests at 30 min (R1) and 40 min (R2) post-injection. A mixed model for crossover design was used to determine the effect of noise exposure and time on either spontaneous behavior scores or delta-g. The restraint scores were analyzed using a two-way repeated measures ANOVA.ResultsSpontaneous behavior scores indicated less sedation during Noise 2 compared to Control+ (P = 0.05). R2 restraint scores for all DM treatments except Noise 2 indicated significantly higher sedation than Control− [C+ (P = 0.003), M (P = 0.014) and N1 (P = 0.044)].DiscussionResults suggest that the quality of sedation is negatively impacted by high-intensity noise conditions (80–85 dB), but exposure to music did not improve sedation in this population of research dogs.

Objective: To review the sources, adverse effects, diagnosis, treatment, and prevention of psychogenic stress in hospitalized human and veterinary patients. Data Sources: Data were collected by searching PubMed for veterinary and human literature from the past 10 years. Human Data Synthesis: Psychogenic stress has been linked to immune suppression; gastrointestinal, cardiovascular, and cutaneous diseases; delayed wound healing; alterations in pain perception; and neurologic impairment. Sources of psychogenic stress include environmental alterations such as excessive noise and light, social and physical factors, sleep disruption, drugs, and underlying disease. Nonpharmacologic options for stress reduction include environmental and treatment modifications, music therapy, and early mobilization. Pharmacologic options include sedation with benzodiazepines and dexmedetomidine. Trazodone and melatonin have been examined for use in sleep promotion but are not currently recommended as standard treatments in ICU. Veterinary Data Synthesis: Activation of the stress response in veterinary patients is largely the same as in people, as are the affected body systems. Possible sources of stress can include social, physical, and environmental factors. No gold standard currently exists for the identification and quantification of stress. A combination of physical examination findings and the results of serum biochemistry, CBC, and biomarker testing can be used to support the diagnosis. Stress scales can be implemented to identify stressed patients and assess severity. Nonpharmacologic treatment options include low-stress handling, pheromones, environmental modifications, and sleep promotion. Pharmacologic options include trazodone, benzodiazepines, dexmedetomidine, and melatonin. Conclusion:The prevalence and clinical significance of psychogenic stress in hospitalized veterinary patients is unknown. Future studies are needed to specifically examine the causative factors of psychogenic stress and the effects of various therapies on stress reduction. The recognition and reduction of psychogenic stress in veterinary patients can lead to improvements in patient care and welfare.

Con el fin de evaluar la influencia de la musicoterapia como tratamiento coadyuvante en la recuperación de pacientes posquirúrgico, se seleccionaron 20 perras mestizas entre 3 años y 6 meses, con un peso promedio de 10,90 ± 0,58 kg, sin enfermedades preexistentes, las cuales se sometieron a ovariosalpingohisterectomía (OSH) realizada por línea media. Fueron elegidos al azar 10 animales que se sometieron a musicoterapia (T1), mientras que el resto permanecieron como grupo control (T2), con igual alimentación. Se estudiaron las variables dolor (DL) (a través de la escala modificada de Melbourne y Glasgow), frecuencia cardiaca (FC), frecuencia respiratoria (FR), consumo de alimento (CA) y peso final (PF), durante siete días. Las observaciones se analizaron a través de una prueba de T-Student. Los resultados fueron promedios, con efectos estadísticos (p 0,05), para T1 de 1,49 (DL); 20,85 r. p. m. (FR); 402,66 g (CA) y 12,65 kg (PF). Mientras que para el control (T2) fueron de 6,82 (DL); 28,28 r. p. m. (FR); 357,69 g (CA) y 11,92 kg (PF). Se concluye que la musicoterapia (T1) posquirúrgica en estas condiciones es una alternativa viable en la recuperación del paciente.

Abstract: Our results indicate that the development of sensory processing of acoustic stimuli is maintained by cats under general anaesthesia and reveal the influence of music on the autonomous nervous system, as measured using HR and SBP.
