Midazolam sedation is a useful intravenous adjunct to local or regional anesthesia for a variety of therapeutic and diagnostic procedures. Midazolam sedation in doses of 1.0 to 2.5 mg IV (onset within 30-60 sec, time to peak affect 3 to 5 minutes, duration of sedation 15 to 80 minutes) is effective for sedation. Titrated intravenous […]
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;
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
Halogenated volatile agents are inhalational anesthesia gases used during surgeries to provide general anesthesia. They are metabolized to varying degrees. There is biotransformation in the liver resulting in cleavage and dehalogenation by the specific enzyme P450, which is a haemocytochrome present in the hepatic cell. Desflurane (CHF2-O-CHFCHF3): It is one of the halogenated volatile agents
The effect of agonist drug of opoid group have a lot of impact as listed: Cough: The cough center in medulla is suppressed, leading to antitussive action. Pure agonists especially related with codeine have pronounced effect. Nausea and Vomiting: The emesis is usually due to direct stimulation of chemoreceptor trigger zone (CTZ) of area postrema of the
Ketamine Uses are many; here we are describing some of them. NMDA antagonists like ketamine were shown to be effective in suppressing the symptoms of opiate withdrawal. Subanesthetic doses (0.5 mg/kg/hour) of ketamine are effective in the correction of acute precipitated opiate withdrawal. Its use as an sedative is well known. The most common use
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
Midazolam pediatric dose loading dose may be followed by a continuous IV infusion to maintain the effect. IV loading doses should not be used in neonates. Continuous IV infusion for sedation in critical care settings is important in pediatric patients. To initiate sedation using midazolam, an IV loading dose of 0.05 to 0.2 mg/kg administered
Cause of hypoxia Common cause of hypoxia and Cyanosis are : 1. Factors present before the operation • Oedema of glottis • Ludwig’s angina • Bilateral quinsy 2. Carcinoma of larynx 3. Tracheal compression and stenosis due to any cause 4. Foreign body in bronchus 5. Carcinoma of bronchus 6. Acute or chronic bronchial asthma
Etomidate induces loss of consciousness rapidly (5—15 seconds) and recovery occurs in 5 to 15 minutes. The elimination Etomidate half life is 4.6 +1- 2.6 hours and total apparent volume of distribution, 4.5 +/- 2.2 L/kg. The volume of distribution of etomidate half life is large, suggesting considerable tissue uptake. The plasma clearance is 879
