Plain-English summary
A 580 kg horse experienced intense itching after receiving a single dose of preservative-free morphine through a catheter placed in its lower back. About 4 to 8 hours after the injection, the horse developed some hair loss and fluid oozing in the area where the catheter was inserted. This reaction was linked to the morphine given through the catheter. The treatment caused some localized irritation, but it was not a serious issue overall.
Abstract
Pruritus following a single administration of 100 microg kg(-1) of preservative-free morphine sulphate given via an extradural catheter was seen in a 580 kg horse. The catheter was placed in the first intercoccygeal space. Focal irritation, represented by both local alopecia over the left gluteal muscles and serum exudation, occurred 4-8 hours after injection. This was attributed to the extradural morphine administration.
