Data are reported as median (range) where indicated. This is attributable to the fact that all subjects had their propofol infusions frequently titrated to a specific level of sedation and were allowed to emerge to a light level of sedation before  being weaned from mechanical ventilation. Measured probabilities are derived from observed sedation scores at various plasma propofol concentrations using the technique of Somma et al. For Adult 55 years and over. Subjects were given intravenous or epidural infusions of fentanyl (up to 200 μg/h) as needed for analgesia. Intensive Care Med 1991; 17: 424–6, Valente JF, Anderson GL, Branson RD, Johnson DJ, Davis K, Porembka DT: Disadvantages of prolonged propofol sedation in the critical care unit. Fig. For sedation, Group 1 will receive intravenous dexmedetomidine 0.3 ug/kg bolused at the onset of the procedure followed by titrated doses of propofol. Eligible individuals received no propofol within 30 days of enrollment into the study. The propofol administration profiles for each group are summarized in table 3. This revised model differs significantly from the original model both numerically and in terms of its superior ability to predict plasma propofol concentrations. Pediatr Emerg Care. The pharmacokinetics of propofol in critically ill patients being given continuous intravenous infusions for sedation 1–4differ significantly from the pharmacokinetics of propofol in healthy surgical patients being given intravenous boluses or short-term infusions of propofol for anesthesia. † Modes = plasma propofol concentrations corresponding to the maximum probabilities for discreet sedation score (SS) (SS = 2, 3, … 5). drugs for paediatric sedation. A detailed summary of the pharmacokinetic and pharmacodynamic analyses can be found in Appendix 1 (Web Enhancement). * C50,SS= plasma propofol concentrations where P(Sedation ≥ SS) = 50%. The emergence times from light sedation (i.e.,  the time it takes for the SS to decrease from 3 to 2) remained fairly rapid (i.e., < 35 min) for propofol infusions lasting 3 days or less. Sedation for diagnostic and surgical procedures in children over 1 month of age: Doses and administration rates should be adjusted according to the required depth of sedation and the clinical response. § Compared with a simple three-compartment model without covariates. Then, these models were prospectively tested in the test group. Corresponding emergence times from deep sedation (sedation score = 5 --> 2) with propofol were 25, 59, 71, and 74 h. Emergence time from sedation with propofol in ICU patients varies with the depth of sedation, the duration of sedation, and the patient's body habitus. Crit Care Med 1998; 26: 676–84, Buckley PM: Propofol in patients needing long-term sedation in intensive care: An assessment of the development of tolerance. This confusion was attributed to persistent effects of propofol because all three subjects had been given propofol for greater than 7 days and had detectable concentrations of propofol in their plasma for up to 5 days after infusion. Maintenance dose for sedation between 0.1-0.2 mg/kg/min or 25-50 mg IV PRN in healthy patients < 55 years of age; Antiemetic dosing, 10-20 mg IV or 10 μg/kg/min infusion; Adjunctive medications. In this study, patients were given an induction bolus dose of propofol followed by a continuous infusion. * Pharmacodynamic parameters estimated from learning group (n = 20). Eye closure was observed at 1.0 +/- 0.4 min after the start of insusion. Plasma propofol concentrations corresponding to the probability modes for sedation scores of 2, 3, 4, and 5 were 0.25, 0.6, 1.0, and 2.0 microg/ml. Conscious sedation, medically known as procedural sedation and/or moderate sedation, is a procedure to relieve anxiety and depress the level of consciousness in patients, before minor procedures. Since propofol lacks analgesic effects, larger doses and thus deeper sedation may be required in the absence of opioids that typically enhance the anesthetic regimen . Sedation guidelines for midazolam infusion during combined spinal and epidural anesthesia. An integrated pharmacokinetic-pharmacodynamic model was used to construct dosing regimens for light and deep sedation with propofol in ICU patients. The peak probability (modes) of each curve defines the plasma propofol concentrations at which a discrete level of sedation is most likely to occur. Sarridou DG, Chalmouki G, Braoudaki M, Siafaka I, Asmatzi C, Vadalouka A. Epub 2011 Aug 23. Much research has since demonstrated its safety in adults and children. With the variable rate infusion method, patients will generally require maintenance rates of 25 mcg/kg/min to 75 mcg/kg/min (1.5 mg/kg/h to 4.5 mg/kg/h) during the first 10 minutes to 15 minutes of sedation maintenance. The propofol infusion data for the learning group were compared to those of the test group using the Wilcoxon rank test with the summary results expressed as median (range). Table 7. ‡ Based on prospective testing in the learning group (n = 19). Get the latest research from NIH: https://www.nih.gov/coronavirus. The accuracy of this pharmacodynamic model, like the pharmacokinetic model, was preserved when prospectively tested in a similar group of ICU patients. Three subjects had mild confusion lasting several days after discontinuation of their propofol infusions. 2. Recovery was faster after propofol (p < 0.02), albeit with a higher degree of agitation. 1987 Jan;42(1):3-6 This was responsive to airway re-positioning manoeuvres and insertion of an oropharyngeal airway. For debilitated patients use dose for 55 years and over.
