The most significant Methodone feature is its exactly identical pharmacodynamics and methodone mechanism of action as that of morphine in equipotent (equianalgesic) doses. Methodone is an agonist with diphenyl structure (2 phenyl rings at the center). The psychological behaviour of methadone addiction is not as markedly abnormal as that of other pure agonists like heroin,
Propofol is known to possess direct antiemetic effects. Propofol antiemetic use for induction and maintenance of anesthesia has been shown to be associated with a lower incidence of postoperative nausea and vomiting (PONV) when compared to any other anesthetic drug or technique. It has been shown that total intravenous anaesthesia (TIVA) with propofol for anesthesia
The binding site is called the ‘receptor’ and the mechanism as opioid receptor mechanism . Any pharmacological activity requires an agent, a target organ and a specific binding site in that organ. The receptor due to its affinity to the drug and opioid receptor mechanism , permits attachment of the drug to itself, which then
Phenobarbital liver in the absence of other drugs, produces only modest decreases in hepatic blood flow. Induction doses of thiopental do not alter postoperative liver function tests. Barbiturates increase hepatic bile flow. However, there is no correlation between the increase in bile flow and the cytochrome P-450 concentration in the liver. Thiopental decreases intraocular pressure
Succinylcholine hyperkalemia is hyperkalemia seen after the usage of succinylcholine. Succinylcholine is a depolarizing muscle relaxant used for urgent endotracheal intubation in the operating room, intensive care unit (ICU), and emergency department. The intravenous (IV) dose is 0.5 to 1.5 mg/kg. Time to effect is 1 minute and duration of action in patients with normal
Physiotherapy management electrotherapy is the application of electrical current to the area of generation of nociception. Physiotherapeutic methods are based on use of mainly two different modalities: 1. Electrotherapy 2. Exercise therapy This can be achieved with following methods of electrical current: • Low frequency • Medium frequency • High frequency Low frequency: i) The
Acupuncture physiotherapy pain reduction technique is an ancient Chinese modality used for various chronic painful conditions, in addition to non pain related problems like acute asthma, chronic sinusitis, etc. The human body has a life force or energy flowing — Chi. This life force is flowing through various channels — Meridians. The life force (Chi)
The detailed description of half life of phenobarbital is discussed here. Thiopentone produces hypnosis within 30 to 40 seconds of intravenous injection. For the half life of phenobarbital , the time required for equilibration of the brain with the thiopental concentration in the blood (effect-site equilibration time) is rapid. Recovery after a small dose is
Clinical Features for acute opioid toxicity treatment is necessary at times.The clinical occurrence of acute opioid toxicity is due to any of the following three main reasons: • Clinical overdosage: Either iatrogenic or patient-controlled analgesia pumps. • Accidental overdosage by addicts. • Attempts at suicide. Whatever might be the cause, “high degree of suspicion” is
Etomidate mechanism of action is shown here. The GABAA receptor plays a central role in the etomidate mechanism of action Etomidate exerts its effects on the receptor by binding directly to a specific site or sites on the protein and allosterically enhancing the apparent affinity of GABA for its receptor. At much higher concentrations etomidate
