Common drugs used in Chicago Sedation Dentistry p2

Below is more details of what emergency sedation dentist in Chicago IL may prescribe.

 

Given the powerful bronchodilator effect of ketamine, this is a pretty good choice for induction of symptomatic asthmatic patients. The usual dose of ketamine is 3-5 mg. / Kg. for intravenous (IV) and 5-10 mg / kg. for intramuscular (IM). The onset of amnesia occurs approximately one minute after intravenous administration and from 5 to 8 minutes after IM administration Pharmacokinetics distribution of ketamine is rapid redistribution half-life is 10 minutes, which completes its action after an IV dose in a span of 10 minutes. Clearing Your Life Average is 3 hours and is mainly due to its hepatic metabolism. Adverse effects: These are essentially the nightmares and hallucinations which are present in approximately 30-40% of patients in whom it is administered. The concomitant use of benzodiazepines such as diazepam and midazolam significantly decrease the incidence of this unpleasant effect. Advised against psychiatric patients. Another adverse effect of ketamine is the increase in blood pressure and myocardial oxygen consumption, so it should be used with caution in patients with coronary disease or vascular aneurysms. Significantly Increases Cerebral Blood Flow, so it is not indicated in patients with Intracranial Hypertension. Another adverse effect of ketamine is significant stimulation of oral secretions so it is recommended antisialogogos agent pretreatment. Etomidate : The etomidate (Hipnomidato), is a derivative action Bencilimidaz├│lico very short, rapidly produces unconsciousness and poor analgesia, produces little myocardial depression, reduces blood flow and intracranial pressure. Dose: 0.3 to 0.4 mg. / Kg Pharmacokinetics: Quick Start, 30 to 60 seconds, the duration of the effect is 3 to 5 minutes, depending on the redistribution to well-perfused tissues such as muscle, liver and skin, is primarily hepatic biotransformation. Adverse effects: There may be irritation at the injection site, nausea and vomiting upon waking, myoclonus (state characterized by small muscle contractions without motor effect). The use of narcotics or benzodiazepines prior to the use of etomidate, reduces significantly this last complication. Another adverse effect of etomidate, constitutes the inhibition of the steps in the synthesis of adrenal steroids. After a single dose can be observed etomidate inhibition of response to ACTH. There is significant evidence that this effect can produce complications or postoperative trans. Benzodiazepines: Benzodiazepines are drugs that can also be used during anesthesia, are usually used on Diazepam and Midazolam (Doricum) (19). Other Benzodiazepines are used for the premedication in order to reduce patient anxiety to be subjected to an intervention. Pharmacokinetics level Benzodiazepines CNS produce sedation, hypnotic effect is much slower than other intravenous anesthetics produce muscle relaxation, anterograde amnesia and anticonvulsant effect possess excellent. A cardiovascular system level Benzodiazepines minimally reduced blood pressure and cardiac output. Large doses may be associated with decreased peripheral vascular resistance, this effect is potentiated by concomitant use of narcotics and halogenated. In small doses the respiratory system can cause a decrease in tidal volume and respiratory rate should be used with caution in patients with chronic obstructive bronchopulmonary disease or in the elderly because respiratory depression may occur, especially after intravenous administration. Dosage: For induction with Midazolam, doses are employed from 0.15 to 0.35 mg. / Kg. and for sedation dose may be used 0.02 to 0.08 mg. / kg .. Diazepam with sedation can be achieved with doses of 0.03 to 0.1 mg. / Kg, and used for the induction dose of 0.3 to 0.4 mg / kg, although higher doses may be required. Diazepam should not be used by the intramuscular route because its absorption is erratic and produces a lot of pain at the site of injection. Benzodiazepines doses should be reduced in the presence of elderly, debilitated or who have used other CNS Pharmacokinetics The maximum effects on the CNS of Midazolam, occurring in most patients 2 to 3 minutes after administration intravenous and duration of this effect ends after rapid distribution. It is well absorbed intramuscularly and effectiveness begins between 15 and 30 minutes, achieving peak plasma concentrations at 45 minutes. Average Life Elimination of Midazolam is 2.5 hours. As for Diazepam can say that its effect appears in 2 to 5 minutes after the IV dose Elimination Half Life is 20 to 40 hours but some metabolites of diazepam, desmethyldiazepam like, reach periods of up to 140 hours to achieve Average Life Elimination complete. Adverse effects: Diazepam has been associated with phlebitis and venous thrombosis, Diazepam has been attributed to birth defects in humans. Another precaution to be taken with the use of Diazepam, is not administered with Valproic acid, as described Psychotic crises after administration of the association. Propofol: Propofol (20). (Di-isopropyl-phenol) is a fast-acting agent belonging to the group of phenols, small doses do not increase pain sensitivity, as occurs with small doses barbiturates that happen to be hyperalgesic. Pharmacokinetics after administration of a single dose in the “bolus”, the concentration decreases rapidly due to its distribution appearing in time anesthesia arm-brain distribution. After administration of a dose on the “bolus” isolated, there is a rapid distribution of the drug to the tissues, the distribution half-life (t 1/2 ╬▒) is from is 1.8 to 4.7 minutes. Slow elimination is through the kidney, approximately five days, the metablosmo is made in the liver and gut, lung secondarily. Other intravenous anesthetic agents, the Narcotics are also used in routine anesthetic practice, among which we can mention: a) Fentanyl, b) Alfentanil c) Sufentanil d) Morphine d) Demerol.
