Table 2 Mean ± standard deviation of heart rate (HR), systolic arterial blood pressure (SAP) and end-tidal isoflurane concentration (FE’ISO) recorded during anesthesia of cats undergoing ovariohysterectomy treated with local infiltration with physiological saline (0.4 mL/kg; group S, n = 15), ropivacaine (1 mg/kg; group R, n = 15) and ropivacaine/meloxicam (0.2 mg/kg; group RM, n = 15)

From: Comparison of perioperative analgesia using the infiltration of the surgical site with ropivacaine alone and in combination with meloxicam in cats undergoing ovariohysterectomy
