This study was performed in order to investigate the correlation between duration of gas anaesthesia with isoflurane and the reduction of tear production in geriatric patients. The study was conducted on 15 dogs (8 males and 7 females, ages between 9 and 14 years old) that were presented at the Faculty of Veterinary Medicine of Bucharest between September – October 2016. Preanesthetic examination was performed according to ASA status (American Society of Anesthesiologists). Patients premedication was made with Midazolam 0.2 mg/kg and Butorphanol 0.2 mg/kg injected intramuscularly (IM) or intravenously (IV). All dogs were intubated, induction was made with Propofol 4-6 mg/kg IV and maintenance was performed with Isoflurane. All patients had Schirmer Tear Test (STT) readings taken prior to intubation and immediately after the isoflurane was turned off. All dogs that were under isoflurane anaesthesia for less than 30 minutes had a slight reduction of tear production compared with those that exceeded 30 minutes in which it was noticed a drastic decrease in tear production. From the total of 15 dogs: 3 dogs that were under isoflurane anaesthesia for less than 30 minutes had a final STT of 15 mm/min +/- 3 mm/min compared with those in which anaesthesia time exceeded 30-40 minutes where the final STT was 5 +/- 3 mm/min.
