Do you mean what medical treatment associated to surgery in order to avoid postoperative complications?
I always provide analgesics (e.g., 0.1-0.3 mg/kg buprenorphine, twice a day), anti-inflammatory (e.g., meloxicam 1 mg/kg, once per day), wide spectrum antibiotics (e.g., enrofloxacin 5-10 mg/kg, once per day).
