Cardiovascular and respiratory function was studied after epidural injection of lignocaine hydrochloride (3 mg kg 1 ) at the lumbosacral space in dogs premedicated with methadone (0–8 mg kg 1 ), acepromazine (0.3 mg kg 1 ) and atropine (0.6 to 1.2 mg). Analgesia was produced caudal to the third to fifth thoracic dermatomes; there was no significant change in cardiovascular function, respiratory rate, arterial blood pH or blood gas tensions. Relaxation of the hind leg and abdominal muscles was profound and haemorrhage caused a rapid fall in arterial blood pressure accompanied by tachycardia.
