In acupuncture practice
of animals, preanesthetics sometimes are needed. The purpose of
this study was to select the ideal chemical restraint at acupuncture
for gastric motility. Nine healthy mixed breed dogs weighed 10-21
kg and aged 1-3 years old were used in this study. Two EMG surface
electrodes were placed between the seromuscular and the mucosal
layer of pylorus. Twenty minutes after feeding normal gastric motility
was recorded for 60 minutes using physiograph (Narco-Biosystem).
Then preanesthetic treated-gastric motility was observed for 30
minutes. Preanesthetics used were xylazine, diazepam, and acepromazine.
Acupuncture needles were inserted to BL-21 (Wei-Yu) acupoint, and
then changes of gastric motility were recorded for 60 minutes. The
gastric motility following xylazine administration (1 mg/kg, IV)
was markedly decreased. BL-21 (Wei-Yu) acupoints stimulation did
not alter xylazine-induced depression of gastric motility. The diazepam
(1 mg/kg IV) treated-gastric motility was increased mildly 20 minutes
after drug administration. BL-21 (Wei-Yu) acupoint stimulation after
diazepam administration enhanced gastric motility significantly.
The gastric motility following acepromazine (0.3 mg/kg, IM) administration
was not changed compared with normal gastric motility. Application
of traditional acupuncture at BL-21 (Wei-Yu) significantly increased
the gastric motility. Based on these results, acepromazine and diazepam
could be acceptable chemical restraints for acupuncture therapy
of gastric motility, but xylazine couldn't be. |
