Filter by:The purpose of this study is to evaluate the safety and efficacy of dexmedetomidine (DEX) in intubated and mechanically ventilated pediatric intensive care unit (PICU) subjects. The key study objectives are: - To characterize the loading and maintenance dosing of DEX by age group and overall medical condition of pediatric subjects - To evaluate the safety and efficacy of loading and maintenance infusions for sedation in initially intubated and mechanically ventilated PICU subjects - To explore the exposure-response relationship between dose of DEX and clinical measures of sedation and safety
-to determine if propofol sedation leads to shorter recovery times compared to traditional sedation using midazolam plus meperidine
In a recent study by Yuen et al it was shown that preoperative intranasal administration of dexmedetomidine is a useful alternative for oral midazolam in children. However, there is no information on the pharmacokinetics of dexmedetomidine after intranasal administration. The aim of this study is to investigate the comparative pharmacokinetics of intranasally and intravenously administered dexmedetomidine in healthy volunteers. The absolute bioavailability of intranasally administered dexmedetomidine will be calculated. In addition, we will report the effects of intranasally and intravenously administered dexmedetomidine on plasma catecholamine levels, systemic blood pressure, heart rate and sedation. We will also monitor the local and systemic safety and tolerability of intranasally administered dexmedetomidine.
Advances in health care require that more children are given sedation to allow doctors to perform investigations or minor procedures. Sedation drugs have traditionally been given orally (swallowed) by children. However, oral sedation drugs have unpredictable characteristics, such as duration of sedation, which may result in difficulties performing the planned procedure. Anesthetic drugs are now invariably used for sedation in children. These are given through an IV (skinny plastic tube inserted in to a vein). Propofol (white liquid) is the anesthetic drug most commonly used for sedation at BC Children's Hospital for sedation. Propofol has several advantages, including an accurately controllable depth of sedation (how deeply asleep), minimal effect on the heart and circulation and control of reflexes (e,g coughing) during the procedure. Propofol also promotes rapid recovery with less sickness and an earlier return to normal functioning following the procedure. While propofol has many advantages it can cause respiratory depression (reduced breathing rate). This reduction in breathing is more common if propofol is given quickly. When your child is given propofol for their proposed procedure this is performed by a pediatric anesthesiologist who is skilled in supporting breathing should this be required. If your child does not participate in this study they will still receive propofol administered by the anesthesiologist as this is our usual practice. It would be routine to administer the propofol rapidly and then support breathing for a few minutes. This is very safe in the hands of an expert anesthesiologist but can be sometimes more risky in other settings where extensive monitoring and anesthesiologists are not available. This is the setting that propofol is used in many institutions. Our goal is to determine how quickly propofol can be given without reducing breathing to the point that help with breathing is required.
The hypothesis of the study is: Does the Surgical Stress Index (SSI) correlate with the Behavioral Pain Scale (BPS), the Ramsay Sedation Scale (RSS)and/or the Behavioral Pain Scale(BPV) and can therefore be used to monitor the quality of analgosedation in noncommunicative intensive care unit patients?
The study will examine dexmedetomidine levels in the blood of critically ill intensive care patients to understand how it is broken down by the body.
The hypothesis is that systemic remifentanil and Clonidine act in a synergistic manner to relief acute main in an experimental human pain model. Of interest is also the effect of the combination on respiration, sedation and cognitive behavior.
Dexmedetomidine is a sedative drug approved for adult patients, intubated, in intensive care units. We are studying whether this drug is cardiovascularly safe in pediatric patients who have recently been burned.
Evaluate efficacy and safety of dexmedetomidine long term administration in ICU patients who require more than 24 hours sedation.
To determine safety and effectiveness of dexmedetomidine when administered for conscious sedation during flexible bronchoscopy (FB) in patients with Chronic Obstructive pulmonary Disease (COPD).
