Filter by:Hypothesis: There is a statistically measurable correlation between qNOX and rough clinical signs of insufficient anti-nociception such as movements during Laryngeal Mask Airway (LMA) insertion, skin Incision, LMA removal. It will reduce the problem of anticipating the nociception in patients undergoing general anesthesia. Objectives: 1. to compare two indexes of hypnosis, the qCON (Quantium Medical, Spain) with the Bispectral index (BIS™) (Covidien, Boulder CO. USA), in patients undergoing surgery under sedation and general anesthesia. 2. to assess the qNOX index of pain/nociception (Quantium Medical, Barcelona, Spain) and the qCON index of hypnosis. 3. to assess qNOX reliability as a specific indicator of response to nociceptive stimulation.
This study evaluates the ability of high flow nasal cannula versus nasal cannula to oxygenate morbidly obese patients undergoing moderate to deep sedation for gastrointestinal procedures.
Management of analgesia and sedation is an integral component of the medical care of a critically-ill child. Its role is to assure comfort and safety to a patient undergoing painful cares and technical procedures; it can also be, in particular situations like acute respiratory distress syndrome or acute brain injury, a full processing treatment. Sedation involves, most of the time, the association of an opioid and a sedative. The use of these drugs is difficult in children, because of a specific metabolism, inducing tolerance and withdrawal in case of prolonged administration. The COMFORT-BEHAVIOR (COMFORT-B) scale is a validated, simple, reliable and reproducible score evaluating sedation and analgesia. Sedation scoring systems must be used regularly to avoid inadequate sedation. Excessive sedation is associated with poor outcomes like prolonged mechanical ventilation, longer hospitalisation and more frequent withdrawal symptoms. Adult and paediatric data suggest that goal-directed sedation algorithms allow a more appropriate adaptation of the treatment to the patient's need and permit a reduction in the duration of mechanical ventilation. The objective was to evaluate the impact of a nurse-driven sedation protocol in a paediatric intensive care unit on duration of mechanical ventilation, total doses and duration of medications, Paediatric Intensive Care Unit (PICU) length of stay, incidence of ventilator-associated-pneumonia and occurrence of withdrawal.
The aim of the study is to evaluate the efficacy of dexmedetomidine in reducing the need for sedatives and analgesics in the immediate post-operative period in children who underwent surgical correction of complex congenital heart disease
Pharmacokinetic monitoring of midazolam, it's active metabolite and fentanyl in pediatric patients with long-term analgosedation will be performed. Especially, the chronologic sequence of the quantified plasma levels during sedation and during wake-up as well as the correlation to dose and sedation depth will be focused.
The leakage of oropharyngeal secretions around high-volume low-pressure tracheal tube cuffs is usually considered as a major risk factor for bacterial tracheal colonization and subsequent development of ventilator-associated pneumonia. The rate of leakage around the cuff is related to the pressure differential across the cuff, namely the difference between the pressure of the subglottic fluid above the cuff and the tracheal pressure under the cuff. Consequently, positive end-expiratory pressure (PEEP) improves the sealing around the cuff towards fluid leakage. However, this preventive effect of PEEP is compromised during prolonged mechanical ventilation by tracheal suctioning manoeuvre, which may enhance fluid leakage, by decreasing tracheal pressure. Indeed, in a benchtop model, a suctioning manoeuvre, without disconnection of the ventilator, induced a constant fluid leakage past a high-volume low-pressure tracheal tube cuff when performed with a high level of suction pressure (- 400 mbar) and a large size of suction catheter size (16 French).
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.
The study hypothesizes that adding 60% nitrous oxide to a steady state sevoflurance or propofol anesthetic will lead to a decrease in both BIS and Entropy indices during a constant level of surgical stimulus
Sedation may be necessary in intensive care to facilitate diverse therapeutic interventions, but the use of sedative drugs may increase the risk of delirium and long-term cognitive impairment. Thus the implementation and monitoring of sedation remains difficult despite the use of sedation protocols and clinical sedation scores. Attempts to improve sedation monitoring through the use of the electroencephalogram(EEG) have been disappointing. Derived variables based on the unstimulated EEG fail to predict the response to external stimuli at the clinically most relevant light-to-moderate sedation levels, and the overlap between moderate and deep sedation levels is wide. We have demonstrated that long-latency auditory evoked potentials (ERPs)can be used to avoid deep levels of sedation in healthy volunteers during propofol sedation, independent of the concomitant administration of remifentanil. This approach has a potential clinical application for improved monitoring of sedation. Since the effects of different sedative drugs on the EEG may vary widely, the use of ERPs to monitor sedation needs to be evaluated with different sedative drugs. Therefore we will administer two widely used drug combinations (dexmedetomidine/remifentanil and midazolam/remifentanil) in healthy volunteers and record ERPS and processed EEG during clinical relevant sedation levels
Most critically ill patients receive sedative and analgesic drugs to attenuate discomfort and pain. The excessive use of sedatives and analgesics has undesirable effects for patients. Whereas undersedation is mostly easy to identify, oversedation with its associated problems is more difficult to recognize. Stopping sedation daily helps to avoid gross oversedation, but this is not always possible. Monitoring the depth of sedation is difficult and is currently based on clinical assessment and the use of clinical scoring systems. These scoring systems cannot be applied continuously, they are subjective and the level of consciousness can be altered when sedation is assessed. Several methods based on the electroencephalogram have been tested to avoid these problems, but the results have been disappointing so far, so the BIS Monitor an dthe Entropy monitor.We have previously shown that the time-locked cortical response to standard external stimuli (long-latency auditory evoked potentials or event-related potentials; ERPs) can discriminate between clinically relevant light to moderate and deep sedation levels in healthy volunteers, when sedation is induced with a combination of propofol or midazolam with remifentanil. We therefore hypothesized that ERPs may be used to monitor the depth of sedation in ICU patients as well. As the first step to test this hypothesis, we evaluated the use of ERPs to assess the level of sedation in patients undergoing elective major surgery and admitted to the ICU for short term postoperative mechanical ventilation.
