Visual analogue scale for pain intensity is a numerical pain rating scale which uses a 10 cm line with the numbers ranging from 0-10. Patients points out the number that corresponds to the level of pain they are feeling. The significance of the numbers must be explained to the patient. Intensity of the pain is […]
Interventional techniques of musculoskeletal chronic pain management include use of nerve blocks, root blocks, rhizotomies, cordotomy, etc. Musculoskeletal chronic pain management is required during the following : 1. Low back pain – Lumbosacral, spinal/vertebral syndromes – Radiculopathy – Prolapsed intervertebral disc – Lumbar canal stenosis 2. Neuropathies: Trigeminal neuralgias (Tic doloroux) 3. Phantom limb pain,
Among the common benzodiazepines that are used in anesthesia today are three: namely diazepam, midazolam and lorazepam. Benzodiazepines produce varying degree of anxiolysis, sedation, anticonvulsant actions and anterograde amnesia. Benzodiazepines also produce some degree of skeletal muscle relaxation but that is not sufficient for surgical procedures; and they also do not decrease the dose requirements
Anesthetic propofol is a potent intravenous hypnotic agent which is widely used for the induction and maintenance of anesthesia. Propofol is a phenolic (2, 6-diisopropylphenol) derivative that is structurally unrelated to other sedative hypnotic agents. It has been used extensively as an anesthetic propofol agent, particularly in procedures of short duration. More recently it has
The Ketamine induction dose of anaesthesia is, 1 to 2 mg/kg IV or 4 to 8 mg/kg IM. Injection of ketamine IV does not produce pain or venous irritation. Consciousness is lost in 30 to 60 seconds after IV administration and in 2 to 4 minutes after IM injection. Unconsciousness is associated with maintenance of
Diazepam metabolism is carried out by hepatic microsomal enzymes using an oxidative pathway of N-demethylation with the production of desmethyldiazepam, oxazepam, and to a lesser extent temazepam as metabolites. Desmethyl diazepam is metabolized more slowly than oxazepam and is only slightly less potent than diazepam. These metabolites contribute to the sustained effect of diazepam. The
Propofol uses includes that, it does not trigger malignant hyperthermia in susceptible patients or experimental animals. The major Propofol uses are its use as Anesthetic agent or as a sedative. It is the drug most commonly used for induction of anesthesia. It can also be used for maintenance of anesthesia when it is ran as
Propofol phosphate, a water soluble propofol prodrug which is enzymatically converted to propofol, formaldehyde and inorganic phosphate, has been shown to produce sedation and anesthesia. A vegetarian formulation of propofol, Cleofol, has been used in a patient from the Jam community of India. Because it contains no lipid vehicles it is devoid of triglyceridaemia and
Depending upon mechanism of nsaid action involved the drugs can be specifically used to achieve the desired effects. The NSAIDs have been proven to block the synthesis of prostaglandins by inhibition of the enzyme cyclo oxygenase. Cyclo-oxygenase (prostaglandin synthetase) is the enzyme involved in the cell membrane injury related destruction of phospholipids to arachidonic acid,
Once Pure agent scheme of presentation is executed it becomes very easy to deal with all the actions of the drugs of various classes of opioids, including pure agonist opioid . While understanding the pharmacological, systemic effect of these drugs it is logically possible to fix the action as per the neuroanatomical site of origin
