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 […]
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
Physiological response to hypoxia is commonly seen. It depends upon speed and severity of the oxygen lack. The response may be direct or indirect. The direct Hypoxia effects are on cardiorespiratory systems and the secondary effects are due to the failure of organs like brain, liver, kidney and heart. The Hypoxia effects on these organs
S-Ketamine is a water soluble molecule that structurally resembles phencyclidine. The commercial preparation of S-Ketamine is a racemic mixture of two optical enantiomers R(-) and S(+), and a preservative benzethonium chloride. The presence of asymmetric carbon atom results in the existence of two optical isomers of ketamine. The racemic form of ketamine has been the
Midazolam infusion can be used either alone or combined with a narcotic immediately before the procedure, with supplemental doses to maintain the desired level of sedation throughout the procedure. For short endoscopic or short diagnostic procedures and direct current cardioversion, midazolam infusion of 1 mg/mL formulation is recommended for IV sedation to facilitate slow injection.
Barbiturate withdrawal is when sudden stopping of barbiturate drugs causes severe illness and withdrawal. This especially happens when infusions are given in the hospital and abruptly stopped. What are the Barbiturate withdrawal symptoms? In the First 12-16 hours: There is an observable improvement. After 16 hours: nausea, vomiting, anxiety, tremors, abdominal cramps, orthostatic hypotension, restlessness.
Midazolam use is helpful with hypnotic amnesic during maintenance of general anesthesia. It proved superior to thiopental because fewer adjuvant anesthetics are required to maintain an acceptable depth of anesthesia. Midazolam use , however, cannot be implemented alone to maintain adequate anesthesia. It may be used with inhalational drugs as well. The MAC of halothane
Benzodiazepines dependence may produce physical and psychological dependence after chronic (>6 months) use of commonly prescribed low-potency benzodiazepines. Withdrawal symptoms (irritability, insomnia, tremulousness) appear within 1 to 2 days for short-acting benzodiazepines dependence and within 2 to 5 days for longer-acting drugs. When administered to patients who have benzodiazepine induced CNS depression of benzodiazepines dependance, flumazenil produces rapid and dependable
While very effective as an antiarrhythmic, amiodarone therapy is also associated with a wide array of adverse side effects involving the cornea, lungs, liver, skin, and thyroid. Although the majority of amiodarone therapy ‘s adverse effects on these organs result from deposition of the drug in the parenchyma, its effect on the thyroid gland is
Incidences of anaphylaxis have been reported after induction with thiopental. The incidence of barbiturate allergy is estimated to be 1 per 30,000 patients. The majority of the patients who suffer from anaphylaxis due to barbiturate allergy also possess history of chronic allergy. Barbiturate Allergic reactions include urticaria, angioneurotic edema, other skin reactions, agranulocytosis and thrombocytopenic
