COMPARISON OF ORAL KETAMINE-MIDAZOLAM AND CHLORAL HYDRATE-MEPERIDINE-HYDROXYZINE SEDATION REGIMENS IN PEDIATRIC DENTISTRYMerrell, David 01 May 2013 (has links)
Purpose: The purpose of this study was to create an experimental design to compare the regimen of ketamine-midazolam to chloral hydrate-meperidine-hydroxyzine for moderate oral conscious sedation. Methods: Patients between 36 and 83 months of age have been randomly assigned to receive 1 of the 2 regimens. Dosages, times, and vital signs will be recorded. Procedures will be recorded on video for assessment of sedation level and behavior. Patients will be contacted to evaluate postoperative sleeping, discomfort, and amnesia. Data will be analyzed using two-group t-tests (TOST) of equivalence in means to compare the two groups across the study period. Results: Patient enrollment of the study has begun. In order not to break the blind randomized code, future data analysis is pending final data collection. Conclusions: This study will assist clinicians by establishing if a regimen of ketamine-midazolam is a comparable alternative to a regimen of chloral hydrate-meperidine-hydroxyzine for sedations.

Sous-produits de chloration dans les eaux de piscine - Effet de l'ozonation / Disinfection by-products in chlorinoted swimming pool waters - Effect of ozonationFreyfer, Diab Adams 12 December 2012 (has links)
Ce travail a été consacré à l'étude des sous-produits de désinfection formés lors de la chloration des eaux de piscine publiques. En effet, parallèlement à son action désinfectante, le chlore réagit sur les composés organiques et minéraux introduits dans l'eau des bassins par les baigneurs (urine, sueur, ...) pour former des sous-produits indésirables (chloramines et composés organohalogénés).Des analyses d'urée, principal composé précurseur de chloramines inorganiques, ont été effectuées dans une cinquantaine d'eaux de piscine. Les concentrations mesurées ont été comprises entre 0,14 et 3,67 mg/L (valeur moyenne : 1,08 mg/L ; écart-type : 0,70 mg/L). L'étude de la réactivité du chlore sur l'urée (cinétique et consommation de chlore) effectuée sous différentes conditions expérimentales a mis en évidence une très grande stabilité de l'urée en présence de chlore libre dans les eaux de piscines.Les analyses de sous-produits de chloration ont démontré que l'hydrate de chloral représente l'un des sous-produits de chloration majoritaire avec les acides dichloroacétique et trichloroacétique. Cette étude a aussi permis de déterminer la constante cinétique d'hydrolyse de l'hydrate de chloral dans l'eau, l'influence du pH et de la température sur la vitesse d'hydrolyse, ainsi que les potentiels de formation d'hydrate de chloral à partir de quelques constituants de l'urine.La dernière partie de ce travail a porté sur l'étude de la réactivité de l'ozone sur le chlore et sur des sous-produits de chloration ainsi que sur l'étude de l'incidence d'une préozonation des eaux de piscines (en absence et en présence de chlore libre) sur la formation des sous-produits organohalogénés lors d'une post-chloration. / The aim of this work was to study of the formation of disinfection by-products during the chlorination of public swimming pools water. In parallel to its disinfecting action, chlorine reacts with organic and inorganic compounds introduced into the swimming pool water by bathers (urine, sweat, ...) to form undesirable by-products (chloramines and organohalogenated matters).A statistical study of the presence of urea, the major component of urine and sweat, and the main precursor compound of inorganic chloramines, in public swimming poolwater has been made. Measured concentrations were between 0.14 and 3.67 mg/L (mean value: 1.08 mg/L, s.d: 0.70 mg/L). The study of the reactivity of chlorine with urea (kinetic and chlorine consumption) made under different experimental conditions, showed a very high stability of urea in the presence of free chlorine in the pools water.Analysis of chlorination by-products showed that chloral hydrate, with the dichloro and the trichloroacetic acids, is one of the major chlorination by-products found. This study also determined the kinetic rate constant of hydrolysis of chloral hydrate in water, the influence of the pH and the temperature on the rate of hydrolysis and the potential of chloral hydrate formation from some constituents of the urine.The last part of this work was focused on the study of the reactivity of ozone on chlorine and some disinfection by-products, as well as the study of the impact of preozonation of swimming pools water (in absence and presence of free chlorine) on the formation of organohalogenated by-products during a post-chlorination.
