Healing Rate and Gross Appearance of Wounds in Goats Subjected to Exploratory Laparotomy Under Distal Paravertebral Nerve Block and Aquapuncture
In order to determine whether acupuncture affects post-surgical wound healing rate and gross appearance, twelve apparently healthy 1-3 years old female Philippine native goats, weighing 10-20 kg, were subjected to exploratory laparotomy under distal paravertebral nerve block (DPNB) and aquapuncture using 2% chili pepper decoction (AQP). For AQP, eight acupuncture points were stimulated - Acupoints BA04 (four points), 31, 22, 26 and 47 (single points). The rate of wound healing and gross appearance of wounds were determined during the 14-day observation period. Wound healing rate was similar in both groups throughout the 14-day observation period. Complete wound healing was not observed in any of the animals in DPNB, while in AQP 40% of the animals showed complete wound healing. No differences were observed on the occurrence of inflammation, hyperemia, apposition of wound edges and exudate during the 14-day observation period between groups. Increased hair growth was observed in AQP compared to DPNB. The results of the study suggest that aquapuncture analgesia produces relatively more complete wound healing and hair growth than distal paravertebral nerve block in goats subjected to exploratory laparotomy.
