In both dogs, a mass obstructing the glottis was identified following induction of anaesthesia, rendering it impossible to visualize the airway with laryngoscope use. Oxygen supplementation by face mask was ineffective and hypoxaemia worsened during repeated attempts to secure the airway. To facilitate digital intubation, the operator's nondominant index finger was introduced into the mouth, displacing the mass to access the epiglottis and palpate the glottis. The endotracheal tube was then inserted into the trachea with digital guidance, resulting in successfully secured airways in both dogs. Digitally facilitated intubation has not been described in detail or studied in small animal practice, although the technique is performed in larger animal species and in human medicine.

The antelope was initially admitted for lameness assessment of the right thoracic limb and admitted a second time for further lameness evaluation (right thoracic and pelvic limbs). Age and body weight ranged 5-6 months and 40-47 kg, respectively, between admissions. For the first anesthetic (day 1), after 4-6 hours of fasting (free access to water), the antelope was administered intramuscular medetomidine-vatinoxan (0.02 mg kg^-1), midazolam (0.3 mg kg^-1), ketamine (2 mg kg^-1) and butorphanol (0.2 mg kg^-1). Orotracheal intubation was performed 13 minutes after injection and followed by 45 minutes of sevoflurane (approximately 1% expired concentration; Fe'Sevo). Naloxone, atipamezole and flumazenil were administered to hasten recovery. For the nine additional anesthetics (days 35-50), intravenous premedication [midazolam (0.1-0.2 mg kg^-1), combined with butorphanol (0.17 mg kg^-1) for the second anesthetic] and anesthetic induction [ketamine (1.7-3.0 mg kg^-1) and propofol (0.7-2.7 mg kg^-1)] were followed by sevoflurane for maintenance (Fe'Sevo 1.22-2.17% for 40-90 minutes), delivered through an endotracheal tube (8.0-8.5 mm internal diameter). Tracheal extubation was performed 3-18 minutes after sevoflurane discontinuation. Morphine (0.1-0.2 mg kg^-1) and saline (6-10 mL) were injected once daily through an epidural catheter (days 38-47).
