In every species, anaesthesia carries ''risks'' due to the drugs that are used. These risks can sometimes be treatable with appropriate intervention while others may be fatal. For these complications to be detected, careful [[Monitoring Anaesthesia|monitoring]] is essential both during and after the anaesthetic procedure.

This may be due to a volume insuffiency or a primary cardiac problem. Common causes include haemorrhage and peripheral vasodilation due to the anaesthetic drugs. Treatments include [[Fluid Therapy|fluid therapy]] and other [[Interventional Agents|interventional drugs]].

==Post Operative Myopathy==

One of the most important causes of postoperative deaths in horses, '''postoperative myopathy''' is commonly seen in well muscled horses. It is usually detected when the horse first tries to stand upon recovery but can take hours to develop. Clinical signs vary from mild lameness to the horse not being able to support its own weight. It is extremely painful. Efforts to prevent development of post operative myopathy include correct positioning and padding on the anaesthetic table. Treatment involves analgesia.

Treatment includes adequate analgesia, fluid therapy and close monitoring of kidney function via serial blood sampling.
