One of the lorazepam uses , is that the Lorazepam undergoes reliable absorption after oral and I.M. injection. After oral administration, maximal plasma concentrations of lorazepam occur in 2 to 4 hours and persist at therapeutic levels for up to 24 to 48 hours. The recommended oral dose of lorazepam uses preoperative medication which is
Etomidate shortens the onset time of the neuromuscular block with vecuronium. This etomidate drug interactions enhances the bradycardia induced by vecuronium. Miller’s anesthesia says the following about etomidate drug interactions – The specific endocrine effects manifested by etomidate are a dose-dependent reversible inhibition of the enzyme 11β-hydroxylase, which converts 11-deoxycortisol to cortisol, and a relatively minor
One may ask what is methylene blue ? Methylene blue is a water-soluble blue thiazine dye used most commonly as a treatment for methemoglobinemia or as an indicator dye. Its utility as an indicator dye has been applied to several clinical situations including identification of aspiration or placement of nasogastric tubes in critically ill patients;
Autogenic training relaxation technique , systematic alternative tensing and relaxing of muscle groups is taught to patients (autogenic training) leading to deep relaxation and ability. In addition to these, diaphragmatic breathing, focused repetition of words/phrases/prayer (distraction), guided imagery, transcendental meditation, are additional methods used. • Pranic healing, • Psychic healing, • Magnetotherapy, • Aromatherapy, •
The pharmacokinetics of ketamine is characterized by rapid onset of action, relatively short duration of action, and high lipid solubility. Ketamine half life has a pK of 7.5 at physiologic pH. Ketamine half life can be given by multiple routes: IV, TM, SC, oral, sublingual, rectal, nasal, transdermal, epidural, or intrathecal. Peak plasma concentrations of
Despite the rapid clearance of propofol pharmacokinetics by metabolism, there is no evidence of impaired elimination in patients with cirrhosis of the liver. Chronic alcoholism does not change the propofol pharmacokinetics significantly. Extrahepatic elimination of propofol occurs during the anhepatic phase of orthotopic liver transplantation. Renal dysfunction does not influence the clearance of propofol. Patients
Propofol related infusion syndrome is a rare complication firstly reported in paediatric patients and also observed in adults, produced due to prolonged (>48 h) high doses of propofol (>66 mcg/kg/min) intravenous infusion. Even short-term propofol related infusion syndrome for surgical anaesthesia have been associated with development of metabolic acidosis. Propofol related infusion syndrome is characterized
Midazolam can be used intravenously for induction of anesthesia versed . As an inducing agent it produces sleep and amnesia but it does not have any analgesic effect. Midazolam is not as rapid acting as thiopental. At approximately equipotent doses (loss of consciousness), thiopental abolishes the eyelash reflex 50—100% faster than midazolam, but it produces
Reactions such as agitation, involuntary movements, hyperactivity and combativeness are usually reported during midazolam administration . Should such reactions occur, the response to each dose of midazolam and all other drugs, including local anesthetics, should be evaluated before proceeding with the midazolam administration of the drug. For induction of general anaesthesia in healthy patients, the
Etomidate metabolism is rapidly metabolized by hydrolysis of the ethyl ester side chain to its carboxylic acid ester, resulting in a water-soluble, pharmacologically inactive compound. Hepatic microsomal enzymes and plasma esterases are responsible for this hydrolysis. Hydrolysis is nearly complete, as evidenced by recovery of < 3% of an administered dose of etomidate metabolism as
