During anesthetic induction, the relevance of neuromuscular blockade (NMB) onset monitoring cannot be asserted and its superiority over waiting for a fixed delay (corresponding to pharmacokinetic knowledge of the neuromuscular blocking agent used) has not been proven. However, many studies have shown a large inter-individual variability on the delay of the NMB onset. The main objective of othe investigator's study is to compare the quality of laryngoscopy during intubation between the NMB onset monitoring and the expectation of a fixed delay after curarization
The aim of this study is to demonstrate the effect of C-Mac videolaryngoscopy with Miller Blade size 0 and 1 on the intubation conditions in children less than 2 years age with a roll inserted under the shoulders.
In more than one-in-five cases of out-of-hospital cardiac arrest, airways are blocked by vomit and blood. Sometimes, paramedics cannot clear the airway using methods they have been taught. If the airway cannot be cleared, the patient will die. Usually, these patients will have a breathing tube placed into their windpipe (intubation), as this provides protection from vomit and blood. To do this, the paramedic needs to be able to see the entrance to the windpipe. A new method of clearing the airway called SALAD has been used in patients to help insert a breathing tube, but it is not known whether the method can help paramedics. This study will use a manikin to see if paramedics can insert a breathing tube more often on their first attempt, using SALAD.
Patients undergoing suspension laryngoscopy under general anaesthesia have oxygen delivered to their lungs through different methods. Inserting a tube in the trachea is the best means for oxygen delivery. However, it does not allow for optimal visibility of the operated area. Other techniques can be used but have disadvantages with some being associated with serious complications. No consensus exists regarding the best airway management technique for this intervention. The aim of the study is to investigate a new device that delivers oxygen at very high flow through a nasal cannula in patients undergoing suspension laryngoscopy under general anaesthesia. This technique allows the surgeon to have a perfect visualisation of the laryngeal structures while allowing the delivery of oxygen for the lungs. After informed consent, adult patients undergoing suspension laryngoscopy under general anaesthesia in two French hospitals will receive high flow oxygen throughout the procedure. At the end of surgery or, whenever applicable, at the time of technique failure (with a decrease in blood oxygen saturation to less than 92%), blood will be drawn for analysis. All patients will have a thin security catheter inserted in their trachea (the currently used technique in both participating hospitals), allowing for rescue high frequency ventilation if ever the study technique fails. The safety of the device will also be assessed by analysing the blood samples for signs of carbon dioxide accumulation and by collecting any intra or post-operative complications. If the device shows to be effective at maintaining blood oxygenation without significant associated risks, it could be used for other surgical situations where airway management is expected to be difficult.
The MILAR trial is a multicenter randomised , prospective, controlled, single-blind, superiority French clinical trial, with a 1: 1 distribution of patients to compare intubation during the first laryngoscopy between the MacGrath MAC videolaryngoscope and the MacIntosh laryngoscope for patients with less than 2 criteria of difficult intubation in elective surgery.
Several videolaryngoscopes have been developed but few have been compared in terms of their learning curves and efficacy. The aim of this study is to compare the learning curves of Airtraq versus King Vision in a group of residents trained in direct laryngoscopy. Four residents will perform, after a short training in manikin, 8 intubations with each device. The sequence of use of the devices will be randomized. Outcome measures will be duration of intubation attempt, glottic visualization and percentage of intubation success.
This study evaluates the correlation between sedation depth monitoring obtained by NeuroSENSE ® NS 701 Monitor and reflexes during intravenous anesthesia in children undergoing direct laryngoscopy for surgical procedures.
Prospective, randomized and controlled who will be conducted in Maisonneuve-Rosemont hospital and whose objectives are: - To observe if the alterations of the NoL index and the standard monitoring (Mean Arterial Blood Pressure and Heart Rate) (using the variability of NoL index and standard monitoring, peak NoL index and peak standard monitoring values, and number of time passed over their respective threshold for nociceptive response) are more accentuated after laryngoscopy using the classical MAC blade versus single-use disposable blade of the Glidescope. - To observe the nociceptive response (using the variability of NoL index and standard monitoring, peak NoL index and peak standard monitoring values, and number of time passed over their respective threshold for nociceptive response) related to the insertion of endotracheal tube between vocal cords during the intubation. Study plans to enroll 50 adult patients scheduled to undergo either general, gynecological, neurological, orthopedic, plastic or urological surgery under general anesthesia and who necessitate endotracheal intubation.
Transnasal High-flow rapid-insufflation ventilatory exchange (THRIVE) has been shown to benefit oxygenation, ventilation and upper airway patency in a range of clinical scenarios, however its use in spontaneously breathing pediatric patients undergoing tubeless airway surgery has not been described. This is a physiologic study that evaluates the feasibility of THRIVE during pediatric airway surgery under self-respiration.
