To evaluate the amount of sleep obtained by hospitalized dogs and cats in an intensive care setting and to identify factors that may impact veterinary patients' sleep.
A prospective, observational study spanning a 4-week period in June of 2020.
Academic teaching hospital.
A total of 96 dogs and 16 cats hospitalized in the ICU during the 4-week study period.
None.
Patient activity was categorized as active, resting, or asleep and was recorded along with ICU environmental data on an hourly basis. Environmental data consisted of subjective assessment of noise level, ambient lighting, number of people present, and number of hospitalized patients. The median observed time asleep was 40% and 11% for dogs and cats, respectively. During natural nighttime hours (9:00 p.m. to 6:00 a.m.), the odds of a patient being asleep were 1.7 times higher if lights were dimmed (p < 0.001). Patients were also less likely to be asleep with higher noise levels (odds ratio 0.66 for each increase in noise level, p = 0.003).
Hospitalized dogs and cats experience sleep disturbances similar to those reported in human ICU patients. Ambient noise and light are significant factors contributing to sleep disruption in cats and dogs hospitalized in a veterinary ICU. The findings of this study support implementing efforts to promote patient sleep through environmental modifications in the veterinary intensive care setting. Additional research is needed to establish objective means of assessing sleep in hospitalized dogs and cats, to determine sleep patterns of hospitalized veterinary patients, and to quantify the impact of sleep disturbances on veterinary patient convalescence.
评估重症监护环境下住院犬猫的睡眠时间，并确定可能影响兽医患者睡眠的因素。
一项前瞻性观察性研究，为期4周，时间为2020年6月。
学术教学医院。
在为期4周的研究期间，共有96只犬和16只猫在重症监护病房住院。
无。
将患者活动分为活跃、休息或睡眠状态，并每小时记录一次，同时记录重症监护病房的环境数据。环境数据包括对噪音水平、环境照明、在场人数和住院患者数量的主观评估。观察到的犬和猫的中位睡眠时间分别为40%和11%。在自然夜间时间（晚上9点至早上6点），如果调暗灯光，患者入睡的几率会高出1.7倍（p < 0.001）。噪音水平越高，患者入睡的可能性也越小（噪音水平每增加一级，优势比为0.66，p = 0.003）。
住院犬猫经历的睡眠干扰与人类重症监护病房患者报告的类似。环境噪音和光线是导致兽医重症监护病房住院猫和犬睡眠中断的重要因素。本研究结果支持在兽医重症监护环境中通过环境改造来促进患者睡眠的努力。需要进一步研究以建立评估住院犬猫睡眠的客观方法，确定住院兽医患者的睡眠模式，并量化睡眠干扰对兽医患者康复的影响。
