A comparative study on some cardiopulmonary effects, anesthesia quality, and recovery time of isoflurane vs. propofol in domestic pigeons (Columba livia domesticus)

BACKGROUND: It is commonly acknowledged that the mostsafe and method of choice anesthesia in birds is inhalation anesthesiabut in some clinical situations, such as tracheal resection,injectable anesthetic agents are the only choice of surgeonsregardless of whether or not an anesthesia machine isavailable. OBJECTIVES: This study aimed to compare the qualityof anesthesia and recovery time of isoflurane and propofol indomestic pigeons. METHODS: Twenty pigeons (Columba liviadomesticus), weighing 302.5±37.95g (Mean ± SD) were randomlyallocated to two groups of ten. One group was anesthetizedby isoflurane (Iso-group), and the anesthesia lasted for 30minutes. The other group received 14 mg/kg of propofol (1%)at constant rate (CRI) through basilica (wing) vein catheter toinduce anesthesia (Pro-group). 1.33 mg/kg per min of propofolwas infused to keep pigeons anesthetized for 30 minutes, usingan injection pump. Temperature, heart rate, respiratory rate,and percentage of oxygen saturation of hemoglobin (SpO2%)were recorded in all three phases including before inductionof anesthesia, during anesthesia at minutes 1, 3, 5, 10, 15, 20,25 and 30, and after recovery time in both groups. RESULTS:Anesthesia caused significant effects on respiratory rate, heartrate, and SpO2% (p?0.05). Recovery times in both groups weresignificantly different (longer in propofol group). CONCLUSIONS:Our findings revealed that the pigeons anesthetized withisoflurane have a soft and fast anesthesia; however, the pigeonswere anesthetized with propofol, had a rough induction thatwas not uniform for all pigeons. Isoflurane showed that it issafer than propofol to anesthetize pigeons.
