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 […]
Propofol contamination in an emulsion formulation, has been associated with infective complications. It becomes contaminated once the ampoules have been opened. Propofol contamination supports the growth of all microorganisms. Diphtheroid bacilli and coagulase-negative staphylococci were the most frequent microorganisms. Others are E. coli, S. aureus, and P. aeruginosa. Adding lidocaine, or storing opened ampoules at
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
The original formulation of Etomidate injection contains propylene glycol as a solvent contributing to a high incidence of pain during IV injection and occasional venous irritation. The newer lipid emulsion formulation is devoid of pain on injection and venous complications such as reddening, swelling, induration; as well as allergic reactions, whereas the incidence of myoclonus
All of these nonsteroidal anti inflammatory drugs side effects collectively lead to breach of the integrity of gastric mucosal lining, and gastric ulceration is the result. Following are the nonsteroidal anti inflammatory drugs side effects : Gastritis : As an overall decrease in production of prostaglandins takes place. Some of the protective PGs like PGE1, PGE2,and

Based on the pharmacokinetic parameters and reported clinical experience in preterm and term midazolam in neonates , continuous IV infusion of midazolam should be initiated at a rate of 0.0005 to 0.001 mg/kg/mm (0.5 to 1 mcg/kg/min). IV loading doses should not be used with midazolam in neonates ; rather the infusion may be run
The mechanisms for ketamine induced cardiovascular effects are complex and also Ketamine effect on blood pressure characteristics. Direct stimulation of the CNS leading to increased sympathetic nervous system outflow seems to be the most important mechanism for cardiovascular stimulation. One of the characteristic of Ketamine is related to blood pressure and is therefore termed as
To know about Ketamine mechanism of action we need to know that Ketamine is a non-competitive antagonist to the phencyclidine site of N-methyl-d-aspartate (NMDA) receptor for glutamate, though Ketamine mechanism of action has effects that are mediated by interaction with many others receptors. N-Methyl-D-Aspartate Receptor Antagonism : NMDA receptors are ligand-gated ion channels that are
Effects of Barbiturates on the body are listed here. Thiopentone decreases the tidal volume and the effect on respiratory rate is biphasic ranging from tachypnea during light anesthesia to a progressive slowing of respiration with deepening anesthesia. However, like propofol, functional residual capacity is not reduced by thiopentone. Effects of Barbiturates on the body administered
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
