Unit II: E
Skeletal Muscle Relaxants
By: Muhammad Aurangzeb
Lecturer-INS/KMU
Objectives
By the completion of this section the learners will be able to:
•Discuss common symptoms/disorders for which skeletal muscle relaxants are used.•Describe uses and effects of skeletal muscle relaxants.•Differentiate between centrally acting and peripherally acting muscle relaxants •Describe non-pharmacologic interventions to relieve muscle spasm and spasticity.•Apply the nursing process with clients experiencing muscle spasm or spasticity.•Calculate the drug dosages accurately.
Skeletal Muscle Relaxants (SMRs) •Drugs that act peripherally at neuromuscular junction/muscle fiber or centrally in the cerebrospinal axis to reduce muscle tone or cause paralysis •A muscle relaxants is a drug that affects skeletal muscle function and decreases the muscle tone.
Common Symptoms/Conditions in which SMRs are used
•In conjunction with GA:
–Facilitate intubation of the trachea –Facilitate mechanical ventilation –Optimized surgical working conditions
•In Muscle spasm: a sudden involuntary contraction of one or
more muscle groups and is usually an acute condition associated with muscle strain (partial tear of a muscle) or sprain –Musculoskeletal Injury or Sports Injury –Low Back pain or neck pain –Fibromyalgia, tension headaches •It may be used to improve symptoms such as muscle spasms, pain, and hyperreflexia.
