Electroencephalography (EEG) spectral edge frequency for assessing the sedative effect of acupuncture in dogs.
Electroencephalography (EEG) is an effective method for the evaluation of sedation or anesthesia. The purpose of this study was to examine the sedative effect of acupuncture by electroencephalographic spectral edge frequency (SEF) in Miniature Schnauzer dogs (4.2-6.1 kg, 1-2 years old). The acupuncture points "GV20 and Yintang" were applied for 20 min. Sedation level was assessed before, during, and after acupuncture by spectral edge frequency 95 values and the Ramsay sedation score. The spectral edge frequency 95 values were significantly reduced during acupuncture on GV20 or Yintang point and returned to the baseline values after acupuncture releasing. The Ramsay sedation score (RSS) also showed the acceptable sedation level during acupuncture. It was concluded that an acupuncture application at GV20 or Yintang point used in the present study would be a valuable method to induce the sedation in dogs.
