General anesthetics

General anesthetics

General anesthetics are medicines that render a patient reversibly unconscious and unresponsive in order to allow surgeons to operate on that patient. 
General anesthetics are normally administered intravenously or by inhalation by a specialist doctor called an anesthetist who also monitors the patient's vital signs (breathing, heart rate, blood pressure, temperature) during the procedure. 
While under general anesthesia, a patient is unable to feel pain and will likely wake with some short-term amnesia (memory loss). Experts are unsure exactly how general anesthetics work.

Ketamine:

  • It is used to cause sleep during care.
  • It is used to put you to sleep for surgery.
  • It may be given to you for other reasons. Talk with the doctor.
Propofol
Propofol (Diprivan) slows the activity of your brain and nervous system.
Propofol is used to help you relax before and during general anesthesia for surgery or other medical procedures.
Propofol is also used to sedate a patient who is under critical care and needs a mechanical ventilator (breathing machine).
Thiopental
Thiopental is a barbiturate (bar-BIT-chur-ate). Thiopental slows the activity of your brain and nervous system.
Thiopental is used to help you relax before you receive general anesthesia with an inhaled medication.

Anticonvulsants

What are Anticonvulsants? Anticonvulsants (antiepileptics or AEDs) helps to normalise the way nerve impulses travel along the nerve cells which helps prevent or treat seizures. When the brain is working normally the nerve cells talk to each other using controlled electrical signals from one nerve cell to another. This tells the body to do everything it needs or wants to do. During a seizure there is a change in the level of nerve cell electrical signals from a normal level to an excessive or abnormal amount of nerve signals. This increased nerve activity is responsible for the signs and symptoms of a seizure. What causes the change is nerve impulses can be the result of an injury to part of the brain, stroke, brain tumor, genetic causes, metabolic problems or toxicity issues. Anticonvulsants can also be used to treat nerve pain and bipolar disorder. How they work? Anticonvulsants keep the nerve cell impulses to a normal level so they don’t become excessive and uncontrolled, w...

Muscle relaxants

Muscle relaxants Muscle relaxants (also called skeletal muscle relaxants) are a diverse group of medicines that have the ability to relax or reduce tension in muscle. Some (such as baclofen, methocarbamol, and tizanidine) work in the brain or spinal cord to block over-excited neuronal (nerve) pathways. Others (such as dantrolene and botulinum toxin) act directly on muscle. Cannabis extract is thought to have a dual effect. Muscle relaxants treat two main conditions: spasticity (stiff, rigid muscles) caused by conditions such as cerebral palsy, multiple sclerosis, and stroke; or muscle spasms which are typically temporary and associated with conditions such as tension headache, low back pain, or fibromyalgia. Only three muscle relaxants - baclofen, dantrolene, and tizanidine are FDA approved to treat spasticity; however, six (carisoprodol, chlorzoxazone, cyclobenzaprine, metaxalone, methocarbamol, and orphenadrine) are approved to treat muscle spasm. Botulinum toxin is only appro...
