“…These behavioral changes have been reported in association with the administration of opioids in ruminants, deriving from central nervous system stimulation [ 8 , 29 , 30 ]; changes such as an increase in vocalization and agitation [ 31 ], chewing movements and nystagmus [ 32 ], and excessive tail-wagging [ 21 ] have been reported. These changes are not common when opioids are administered with a sedative or anesthetics agents, or when administered to animals in pain [ 4 ]. This may explain our observation that excitatory behavioral effects were (e.g., exaggerated tail-wagging, chewing movements and restlessness) less pronounced once the lidocaine and ketamine were administered after fentanyl.…”

“…The selection of the best technique for anesthetic maintenance should be based on the intrinsic pharmacological effects of each anesthetic, type of procedure and its duration, on the availability of inhalation anesthetic equipment, on the proficiency in the anesthetic technique, etc. [ 3 , 4 ].…”

“…An alternative to a single agent inhaled anesthesia, is the use of inhaled anesthetics with intravenous drugs (analgesics and/or sedatives), this protocol is known as partial intravenous anesthesia (PIVA) [ 4 , 9 , 10 ] and leads to an improvement in cardiopulmonary parameters, due to the reduction in the anesthetic requirements of inhaled anesthetic agents to prevent intraoperative awareness and thus reducing its dose-related cardiovascular depressing effects [ 11 , 12 , 13 ].…”

“…Because of its pharmacokinetic properties (that allow a rapid onset), ultra-short action, and rapid recovery, propofol has proven to be the most suitable agent for TIVA protocols in dogs, cats, horses, calves and goats [ 14 , 15 ]. Comparatively to inhaled anesthesia, injected anesthesia has a lower cost, and requires minimal equipment for delivery and control [ 4 ].…”

“…Current literature lacks a description of the effects of the combination of fentanyl, lidocaine, and ketamine in goats when co-administered as pre-anesthetics and/or during anesthesia. This description is important because it allows the determination of the sparing and analgesic effects of this combination of agents, and to characterize the post-surgical recovery; good recovery quality is essential for safety and welfare of the patient [ 4 ].…”

This study aimed to compare, first, the anesthetic and cardiopulmonary effects of propofol or isoflurane anesthetic maintenance in goats receiving a fentanyl–lidocaine–ketamine infusion undergoing abomasotomy and, secondly, to compare the quality of the recovery from anesthesia. Two groups were used: propofol (TIVA) and isoflurane (PIVA). Goats were premedicated with fentanyl (10 μg/kg intravenously [IV]), lidocaine (2 mg/kg, IV), and ketamine (1.5 mg/kg, IV). Anesthesia was induced with propofol and maintenance consisted of fentanyl (10 μg/kg/h, IV), lidocaine (50 μg/kg/min, IV), and ketamine (50 μg/kg/min, IV) as constant-rate infusions (CRIs), combined with either CRI of propofol at initial dose of 0.3 mg/kg/min, IV (TIVA), or isoflurane with initial end-tidal (FE’Iso) concentration of 1.2% partial intravenous anesthesia (PIVA). The mean effective propofol dose for maintenance was 0.44 ± 0.07 mg/kg/min, while the mean FE’Iso was 0.81 ± 0.2%. Higher systolic arterial pressure (SAP) values were observed in total intravenous anesthesia (TIVA) during some time points. Recovery was smooth in PIVA, while restlessness, vocalizations, and paddling were observed in TIVA. Both protocols produced a satisfactory quality of anesthesia during surgery, with minimal impact on cardiopulmonary function. Nevertheless, recovery after anesthesia in TIVA might be of poor quality.
