A syrup is effective for producing sedation and anxiolysis at a Midazolam oral dose of 0.25 mg/kg with minimal effect on ventilation even when administered at doses as large as 1 mg/kg. Midazolam oral is the most commonly used oral preoperative medication for children. Midazolam oral dose which is, 0.5 mg/kg given orally 30 minutes before
There are several oxygen physical properties : 1. Oxygen is colorless, odorless and tasteless gas. 2. Specific gravity is 1.106. 3. Molecular weight is 32. 4. In normal atmospheric pressure it liquefies at 183°C. 5. Solubility in water is 2.4 volume% at 37°C and 4.9 volume% at 0°C. 6. Inflammibility—it cannot be ignited but its
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
Midazolam structure is characterized by pH dependent ring opening phenomenon in which the ring remains open at pH values of less than 4, thus maintaining its water solubility. The pK of midazolam is 6.15, which permits the preparations of salts to be water soluble. The parenteral solution of midazolam used clinically is buffered to an
Emergence from ketamine anesthesia in the postoperative period may be associated with audiovisual ketamine hallucinations , confusional state, which may progress to delirium, proprioceptive disturbances (feelings of detachment from the body) and slightly reduced ability to recall objects seen after administration of the drugs. The ability to recall objects seen immediately before drug exposure remains
Diazepam IV is a highly lipid-soluble benzodiazepine with a more prolonged duration of action compared with midazolam. Diazepam IV is dissolved in organic solvents (propylene glycol, sodium benzoate) because it is insoluble in water. Dilution with water or saline causes cloudiness but does not alter the potency of the drug. Injection by either the IM
Activation of NMDA receptors has been implicated in cerebral ischaemic damage. Therefore, by its antagonistic effect on NMDA receptors, Ketamine seizures may have a possible neuroprotective role. Systemic administration of ketamine has been reported to have neuroprotective effect, in terms of preoperative treatment, in preventing ischaemic and postischaemic spinal cord injury during thoracic and thoracoabdominal
Propofol is an insoluble drug that requires a lipid vehicle for emulsification. The standard propofol emulsion formulation contains 10% soya oil as the oil phase and egg lecithin as the emulsifying agent that is composed of long-chain triglycerides. This formulation supports bacterial growth new formulations contain preservatives with bactericidal action, such as propofol with EDTA
The midazolam half life elimination of IM administration is comparable to that observed following the IV administration. Midazolam is approximately 97% plasma protein-bound in normal subjects. In patients with chronic renal failure, the free fraction of drug in plasma can be significantly higher than in healthy adults. In animals and humans, Midazolam has shown to
Midazolam IV is the first benzodiazepine that was produced primarily for use in anaesthesia. Walser and colleagues in 1976 “first described midazolam, the first clinically used water-soluble benzodiazepine. The imidazole ring in its structure accounts for its stability in aqueous solution and rapid metabolism. It is two to three times as potent as diazepam and
