Use of Papaver somniferum and Arnica montana in Ultra-diluted Form to Assist in Anesthesia Recovery and as Analgesia for Dogs having Undergone Ovariohysterectomy
05 February 2020 (online)
Ovariohysterectomy is one of the most frequently performed procedures in veterinary surgery. The objective was to assess the effects of using Papaver somniferum 200 cH and Arnica montana 30 cH in the recovery room and as a postoperative analgesia in dogs that had undergone an ovariohysterectomy. This study was approved by the Ethics Committee for Animal Experimentation of the Integrated University Center (No. 2124/2017).
A total of 40 dogs were considered ASA I (American Anesthesiology Association) after physical and laboratory examinations, and were randomly divided into four groups: Arnica, Papaver, hydroalcoholic and physiological solution, receiving 4 drops of each treatment every 10 minutes over a period of 1 hour. Anesthesia recovery time (in minutes), as well as the duration of the postoperative analgesia (in hours), was measured using the modified Glasgow scale. Heart rate, respiratory rate, systolic blood pressure and rectal temperature were also evaluated during the recovery period. The study was blinded. The data was analyzed using ANOVA, followed by the Tukey test, with p < 0.05 considered a statistically significant difference.
The Papaver-treated group recovered from anesthesia (41±7.6 min) faster than the others: Arnica (65.8±17.3 min), hydroalcoholic solution (68.8±15 min) and physiological solution (55.3±12.5 min); p ≤ 0.05. The Arnica group required rescue analgesia later than the others (17.8±3.6 h): Papaver (6.6±0.9 h), hydroalcoholic solution (5.1±1.2 h) and physiological solution (4.1±0.9 h); p ≤ 0.05. There were no statistically significant differences among the other physiological parameters.
The findings of this study coincide with other studies in the literature. It was concluded that Papaver 200 cH is effective in accelerating anesthesia recovery time in dogs and that Arnica 30 cH can be an alternative in the protocol for acute pain management in these animals.
