Plain-English summary
Sixteen cats were given anesthesia with propofol while undergoing spay surgery (ovariohysterectomy) to compare two pain medications: remifentanil and alfentanil. The cats were monitored for heart rate, blood pressure, and other vital signs during the procedure. It was found that remifentanil resulted in a shorter recovery time after surgery compared to alfentanil, although alfentanil caused lower blood pressure. Both medications worked well for anesthesia, ensuring the cats were comfortable during their surgery.

Abstract
Sixteen cats were used to compare the cardiovascular and anesthetic effects of remifentanil (REMI) or alfentanil (ALF) in propofol-anesthetized cats undergoing ovariohysterectomy. After premedication with acepromazine, anesthesia was induced and maintained with a constant rate infusion of propofol (0.3 mg/kg/min). REMI or ALF infusions were administered simultaneously with propofol. Heart rate (HR), systolic arterial pressure (SAP), pulse oximetry (SpO(2)), rectal temperature (RT), and response to surgical stimulation were recorded at predefined time points during anesthesia. Data [mean±standard deviation (SD)] were analyzed by analysis of variance (ANOVA) for repeated measures followed by a Dunnett's test and Student t-test (P<0.05). SAP was significantly lower in ALF group than in REMI group. Extubation time was significantly shorter in REMI than in ALF group. Overall infusion rate of REMI and ALF was 0.24±0.05 μg/kg/min and 0.97±0.22 μg/kg/min, respectively. The combination of propofol and REMI or ALF provided satisfactory anesthesia in cats undergoing ovariohysterectomy.
