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. […]
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
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
Pentazocine agonist antagonist is supposedly capable of producing spinal level analgesia. However, it produces significant sedation, drowsiness. The drugs which are equidistant to either pure agonists or pure antagonists in the terms of their activity belong to this group, agonists at one receptor and antagonists at another. Two groups of synthetic compounds belong to this
Following are the therapeutic uses of opioid analgesics : 1. Pain relief: By any and all the possible routes, these drugs have been given to relieve the pain—acute, surgical, non-surgical, visceral, somatic, chronic, and oncogenic, non-oncogenic. 2. Morphine is drug of choice in IHD, myocardial infarction, obstetric analgesia. 3. Dyspnoea: Especially due to left ventricular
Ketamine interactions potentiates all non depolarizing muscle relaxants in a dose-dependent manner. Ketamine improves the intubating condition when used with rocuronium. Halothane anesthesia by decreasing uptake, distribution, redistribution and metabolism of ketamine produces significant prolongation of its pharmacologic action on the central nervous system. Ketamine administered in the presence of volatile anesthetics may result in
Ketamine cardiovascular effects resemble sympathetic nervous system stimulation. Indeed, a direct negative cardiac inotropic effect is usually overshadowed by central sympathetic stimulation. HR and BP rise were similar between S(+)ketamine and racemic mixture. Systemic blood pressure, heart rate, cardiac output, cardiac work, and myocardial oxygen requirements all are increased after IV administration of ketamine cardiovascular
Nitroprusside Cyanide Toxicity is due to the cyanide groups released from metabolism of the nitroprusside molecule. After gaining an electron from the iron moiety of hemoglobin, the sodium nitroprusside produces an unstable radical and methemoglobin. Hypertension is commonly seen in the perioperative setting as well as the intensive care unit (ICU). There are many agents
Ketamine analgesia produces intense analgesia at sub anesthetic doses and prompt induction of anesthesia when administered IV at higher doses. Ketamine analgesia has an analgesic action at many sites both centrally and peripherally. These actions are mediated via multiple receptor subtypes, including opioid, NMDA, kainate, and GABAA receptors. Ketamine also inhibits serotonin and dopamine reuptake.
Phenobarbital status epilepticus that does not respond to first-line benzodiazepines (lorazepam or diazepam) or to second-line antiepileptic drugs (phenytoin/fosphenytoin, phenobarbital or valproate) is usually considered refractory and requires more aggressive treatment. Barbiturate anaesthetics, such as pentobarbital and thiopental sodium, are the most frequently used agents and are highly effective for refractory GCSE both in children
