EFFECTS OF OXYGEN AND ISOFLURANE ANESTHESIA ON HEMOLYMPH GAS ANALYSIS AND RIGHTING REFLEX OF ASIAN FOREST () AND DICTATOR SCORPIONS ().

Large arachnids are commonly managed under professional care, and anesthesia is occasionally required for physical examination and diagnostic and therapeutic procedures. Anesthetic responses and hemolymph gas analysis have been studied previously in spiders, but scorpions have yet to be investigated. This study measured hemolymph gas values with an i-STAT point of care blood gas analyzer in healthy adult Asian forest scorpions ( = HL, = 8) and dictator scorpions ( = PD, = 12) breathing: 1) room air (RA), 2) 100% oxygen for 10 min in a chamber (OX), and 3) 5% isoflurane and oxygen (ISO) in a chamber until induction or loss of righting reflex.
