Isoflurane Anesthesia of Wild-Caught Goliath Birdeater Spiders (Theraphosa blondi) and Chilean Rose Spiders (Grammostola rosea)

Abstract: Anesthesia is used in theraphosid spiders to facilitate medical procedures (e.g., physical examination, sample collection, surgery); however, most information on this subject is anecdotal. This study was conducted to systematically determine the anesthetic parameters of wild-caught, subadult goliath birdeater spiders (Theraphosa blondi) (n = 11) and Chilean rose spiders (Grammostola rosea) (n = 12). Each spider was placed in a 3-L gas anesthetic chamber and subjected to an induction of 5% isoflurane at a rate … Show more

“…Results of other studies 4,5 in which isoflurane anesthesia of G rosea was evaluated indicate shorter anesthetic induction and recovery times than those found for sevoflurane anesthesia of tarantulas in the present study. However, differences in anesthetic agents and methods make direct comparisons among these findings difficult.…”

“…The RR was scored on an ordinal scale (0 = normal, 1 = attempted but unsuccessful, and 2 = absent). 4 After induction of anesthesia (defined as the number of minutes until RR was not detected during 2 consecutive evaluation times), spiders were removed from the chamber and administration of sevoflurane was discontinued. Another hemolymph sample was collected from an intracardiac location immediately after removal of spiders from the chamber; these hemolymph samples were processed and analyzed by means of the same procedures used for samples obtained before anesthesia.…”

“…Despite reports of the effectiveness of isoflurane‐based inhalation anaesthesia induction in spiders (Zachariah et al ., ; Dombrowski et al ., ), we find that it had variable performance (Pizzi, ). Some spiders are rendered lethargic after 5–10 min.…”
