Abstract:
Muscle relaxation facilitates tracheal intubation and improves surgical conditions during anaesthesia. However, unexpected prolonged muscle relaxation may occur. This article describes important causes of prolonged muscle relaxation and gives suggestions for its prevention. Drug interactions, incomplete reversal, co-morbidity, inaccurate neuromuscular monitoring and critical illness may prolong the effect of muscle relaxants. The anaesthetist must titrate the muscle relaxants using objective neuromuscular monitoring and proper reversal of the blockade when needed.

Centrally Acting Muscle Relaxants: Therapeutic Uses
Centrally acting drugs are classified into spasmolytic and antispasmodic drugs. Spasmolytic drugs such as baclofen, diazepam, and tizanidine inhibit spinal motor neurons and decrease muscle tone. Spasmolytic drugs are administered for severe and chronic spasms due to multiple sclerosis, cerebral palsy, stroke, and spinal cord and muscle injuries. However,...
