Adjunctive Clonidine in the Sedation of Mechanically Ventilated Children

2014-08-27 03:20:02 | BioPortfolio

Summary

Almost all critically ill children who are mechanically ventilated require sedation and analgesia. Providing effective sedation for children in the PICU requires careful balancing of the need for sedation with the adverse effects associated with sedative medications. Clonidine is often used as an adjunctive sedative and analgesic in children but a well designed and adequately powered randomized trial is required to test the effect of clonidine-based sedation. Because there are no large randomized trials of sedation related interventions among critically ill children there are many unknown factors. This pilot trial, focussing on feasibility outcomes will assess the feasibility of, and inform the design of, a larger randomized controlled trial which will focus on clinically important outcomes.

Description

Almost all critically ill children who are mechanically ventilated require sedation and analgesia. Providing effective sedation for children in the PICU requires careful balancing of the need for sedation with the adverse effects associated with sedative medications. Inadequate sedation may result in undue pain and suffering for children, ventilator dysynchrony and may risk removal of life sustaining devices. Excess sedation limits patients' interaction with their parents and care-givers and may result in delayed weaning from mechanical ventilation, prolonged PICU stay and the attendant risks of increased morbidity. Critically ill children may also experience withdrawal when these medications are stopped. Randomized trails in adults have shown that sedation related interventions can improve patients outcomes, but such trials have not been performed in children.

Clonidine is often used as an adjunctive sedative and analgesic in children but a well designed and adequately powered randomized trial is required to test the effect of clonidine-based sedation. Because there are no large randomized trials of sedation related interventions among critically ill children there are many unknown factors.

This pilot trial, focussing on feasibility outcomes will assess the feasibility of, and inform the design of, a larger randomized controlled trial which will focus on clinically important outcomes.

Clonidine for Prevention of Relapse to Opiate Abuse

The purpose of the study is to determine whether clonidine, given to abstinent patients maintainedon buprenorphine, prevents relapse to opioid use more effectively than placebo.

Comparison of Keppra and Clonidine in the Treatment of Tics

The goal of this study is to confirm that levetiracetam has a better tic-suppressing profile than that of the widely used tic-suppressing medication, clonidine. More specifically, we hypo...

Effects of Clonidine on the Cardiovascular, Renal and Inflammatory Responses to Experimental Bacteremia.

Supra-clinical doses of clonidine appear beneficial in experimental sepsis, but there is limited understanding of the effects of clonidine at clinically relevant doses.

Clonidine as a preoperative sedative.

The purpose of this study was to -examine the use of oral clonidine as a preoperative sedative prior to parenteral moderate sedation. Initially, four patients were given 0.2 mg oral clonidine but redu...

Carrier-mediated uptake of clonidine in cultured human lung cells.

The lung is a preferential organ site for accumulation of lipophilic basic amine drugs, so-called pneumophilic drugs and belonging to various pharmacological classes, which can result in lung toxicity...

Ameliorative effects of clonidine on ethanol induced kidney injury in rats: Potential role for imidazoline-1 receptor.

Chronic alcoholism is a risk factor for kidney injury. Clonidine is an α-adrenergic receptor/imidazoline-1 receptor agonist that can reduce blood pressure and maintain renal functions. This study aim...

Clonidine used as a perineural adjuvant to ropivacaine, does not prolong the duration of sensory block when controlling for systemic effects: A paired, blinded, randomized trial in healthy volunteers.

Clonidine used as an adjuvant to ropivacaine have been shown to prolong the duration of peripheral nerve blocks. The mechanism of action remains unclear. We hypothesized, that clonidine used as an adj...

Medical and Biotech [MESH] Definitions

Artificial respiration (RESPIRATION, ARTIFICIAL) using an oxygenated fluid.

Any method of artificial breathing that employs mechanical or non-mechanical means to force the air into and out of the lungs. Artificial respiration or ventilation is used in individuals who have stopped breathing or have RESPIRATORY INSUFFICIENCY to increase their intake of oxygen (O2) and excretion of carbon dioxide (CO2).

The artificial substitution of heart and lung action as indicated for HEART ARREST resulting from electric shock, DROWNING, respiratory arrest, or other causes. The two major components of cardiopulmonary resuscitation are artificial ventilation (RESPIRATION, ARTIFICIAL) and closed-chest CARDIAC MASSAGE.

Techniques for administering artificial respiration without the need for INTRATRACHEAL INTUBATION.

The act of breathing with the LUNGS, consisting of INHALATION, or the taking into the lungs of the ambient air, and of EXHALATION, or the expelling of the modified air which contains more CARBON DIOXIDE than the air taken in (Blakiston's Gould Medical Dictionary, 4th ed.). This does not include tissue respiration (= OXYGEN CONSUMPTION) or cell respiration (= CELL RESPIRATION).
