The relationship between food deprivation and blood glucose at induction of anaesthesia in juvenile pigs

Research output: Contribution to journalMeeting abstractpeer-review

Abstract

Restricting food for 4 – 48 hours is recommended before general anaesthesia in pigs (Bradbury and Clutton, 2016). However, prolonged deprivation is stressful and may have adverse physiological effects including hypoglycaemia.

In this retrospective observational study, 28 juvenile [age 8 (5 – 11) weeks] female Landrace-cross pigs [18.5 (10 – 34) kg] were anaesthetised for an unrelated, experimental study. Time from food withdrawal until anaesthesia induction was recorded. Blood glucose (BG) was measured (AlphaTRAK, Zoetis) at induction of anaesthesia (isoflurane in oxygen), 10 minutes after preanaesthetic medication with intramuscular morphine (0.3 mg kg-1), medetomidine (7 μg kg-1), midazolam (0.3 mg kg-1) and alfaxalone (2 mg kg-1).
