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 […]
Reiki therapy techniques have been in practice since 2nd—3rd century; it was forgotten and about 130 years back was reinvented by Dr. Mikao Usui. WHO has defined it as “Non physical healing energy comprising universal life force energy (divine in nature) having its own intelligence”. Rei: means in Japanese, universal; Ki : life force energy
What are Barbiturates drugs? Barbiturates are the derivatives of barbituric acid which is a condensation product of urea with malonic acid. Barbituric acid itself is devoid of any hypnotic activity. Barbiturates drugs are hardly soluble in water; however, their sodium salts form alkaline solutions in water. Conventionally, they are divided according to their duration of
The etomidate pharmacokinetics is altered in the elderly, with a decrease in initial distribution volume and clearance (a decrease of 2 mL/min/kg every decade). Compared to normal patients, the cirrhotic patients have normal clearance rates, suggesting that cirrhotic patients metabolize etomidate normally, but the distribution volume and elimination half-life were twice as great. A 30%
Hypnotherapy placebo effect therapy most probably acts via, placebo effects/auto suggestion mechanisms. Anaesthesiologists have been practicing some form of suggestion therapy even in their day-to-day preoperative visits on the eve of surgery. Even a 5-minute preoperative visit will reduce anxiety of patient significantly. Hypnotherapy placebo effect or what was called mesmerism was described in late
Benzodiazepines uses are many. Preoperative medication for anxiolysis and sedation is one where it finds its usage. Midazolam has replaced diazepam as the most commonly administered benzodiazepine in the preoperative period for preoperative medication and intravenous (IV) sedation. Furthermore, the context-sensitive half-times for diazepam and lorazepam are prolonged; and so they are used where prompt
Midazolam metabolism is carried out rapidly by hepatic and small intestine cytochrome P450 (CYP3A4) enzymes to active and inactive metabolites. The principal metabolite of midazolam is 1-hydroxymidazolam, which has approximately half the activity of the parent compound. This active midazolam metabolism is rapidly conjugated to 1-hydroxymidazolam glucuronide and is subsequently cleared by the kidneys. This
Some barbiturates effects are explained here. The thiopental sodium causes profound fall in cerebral blood flow (35 to 40%) and thus ICP. Thiopentone also causes profound decrease in CMRO2. Thiopentone increases Cerebral perfusion pressure (CPP). The barbiturates effects increased the amplitudes of subcortical and early cortical components of somatosensory evoked potentials. Even full suppression of
Once Pure agent scheme of presentation is executed it becomes very easy to deal with all the actions of the drugs of various classes of opioids, including pure agonist opioid . While understanding the pharmacological, systemic effect of these drugs it is logically possible to fix the action as per the neuroanatomical site of origin
Acute on chronic pain description is to explain the pain which was chronic and has now become suddenly severe, sharp and unbearable. It could be due to acute exacerbation of the original process. Aetiologically it could be due to sudden increase in the size of the primary or due to deposition of metastases into long bones,
