Filter by:Study will be conducted in Pediatric Intensive Care Unit (PICU) in King Abdullah Specialist Children Hospital (KASCH), National Guard Health Affairs, Riyadh, Saudi Arabia. Total of 430 patients will participate to assess the safety and efficacy of prolonged Dexmedetomidine use beyond 24 hours in pediatric Intensive Care Unite.
A magnetic resonance imaging (MRI) examination usually takes 30 to 45 minutes and requires the patient to remain perfectly still during the entire acquisition process to ensure quality. Children under 6 years of age are not very cooperative and sedation is required for this age group. Currently, there are no specific recommendations for sedation for a paediatric MRI examination. In 2018, a retrospective study on the sedation protocol applied at Hôpital Universitaire des Enfants Reine Fabiola (H.U.D.E.R.F.) was conducted. In this protocol, premedication was done with oral midazolam and sedation with iterative boluses of propofol. This study concluded that the protocol in place was effective, but found that image acquisition during the procedure was interrupted in 25% of cases, largely due to involuntary movements of the child. Preoperative stress can be emotionally traumatic for the child and may even extend beyond the perioperative period, hence the importance of premedication. For the most anxious children, non-pharmacological means of premedication are often not sufficient. Moreover, the literature shows that pharmacological premedication is useful in reducing parental separation anxiety and in facilitating induction of anaesthesia. Midazolam is an effective premedication agent with some disadvantages (paradoxical reaction, low compliance of oral intake). Dexmedetomidine is a highly effective α-2 receptor agonist that can also be used as premedication according to the current literature. A report by the Pediatric Sedation Research Consortium (P.S.R.C.) shows that it has a safe profile and an incidence rate of serious adverse events of 0.36% in the paediatric population. Furthermore, administered intranasally, it is non-invasive, painless and has good bioavailability (over 80%). The primary objective is to demonstrate the superiority of intranasal dexmedetomidine over oral midazolam as a premedication for bolus sedation of propofol in terms of the incidence of any event during the MRI procedure requiring temporary or permanent interruption of the examination. The impact of dexmedetomidine on the amount of propofol administered and on the post-sedation period, the impact of external factors on the primary objective, the acceptance of intranasal premedication by the children and the quality of the MRI images will also be analyzed.
Drug-induced sleep endoscopy (DISE) is the most used technique for identifying the obstruction site associated with obstructive sleep apnea (OSA). This is due to the fact that it allows many patients to be examined in a daytime setting. This procedure uses sedative drugs to mimic natural sleep. However, associations with the site of upper airway (UA) collapse during natural sleep remain unclear. The aim of this explorative study is to identify UA collapse in patients with OSA using endoscopic techniques as well as flow shape characteristics and sound analyses during natural and drug-induced sleep. Furthermore, we want to optimize the measurement set-up of natural sleep endoscopy (NSE).
The aim of this prospective randomized study is to compare the safety and efficacy of two strategies for sedation of critically ill patients submitted to mechanical ventilation: continuous intravenous infusion of dexmedetomidine versus intravenous bolus of midazolam. The two groups will be compared as to the incidence of of delirium, evaluated with the Confusion Assessment Method for ICU (CAM-ICU) and the percentage of time within the target sedation using the Richmond Agitation-Sedation Scale (RAAS).Eligible patients will be 18 years or older intubated and mechanically ventilated for less than 48 hours prior to start of study drug and anticipated ventilation duration of at least 48 hours. Calculated sample size is 146 patients (73 patients in each group)
