Filter by:The 50% effective concentration of remifentanil by target controlled infusion was not determined for inhibiting the haemodynamic response during double-lumen tube (DLT) intubation. Previous study showed that Airtraq videolaryngoscope provided more stable haemodynamics than Macintosh for double-lumen tube intubation. In this study, the investigators will compare the 50% effective concentration of remifentanil between Airtraq videolaryngoscope and Macintosh laryngoscope for inhibiting haemodynamic responses during DLT intubation.
Endotracheal intubation (ETI) is a potentially life-threatening procedure for critically ill patients and major severe complications such as severe hypoxia, cardiovascular collapse and cardiac arrest are common. Despite the high risk of the procedure, different interventions lack high-quality evidence and the investigators hypothesize that a heterogeneous practice among different centres and geographical areas may be found. The investigators designed a large international observational study aiming at prospectively collecting data on the current impact of ETI-related adverse events and current airway management practice in critically ill patients. Investigators will collect data on all consecutive in-hospital (intensive care unit, emergency department and wards) ETIs performed in adult critically patients.
Hemodynamic monitoring of the critically-ill patients is increasingly performed using an arterial pulse contour-based cardiac output device such as the proAQT system. The aim of this study is to evaluate the effect of extending the pressure lines on the arterial pressure wave and the calculated hemodynamic variables when using the proAQT system.
The study aim is to investigate whether preoperative heart failure has impact on hemodynamic stability during anesthesia induction by target controlled infusion of anesthesia (TCI) in non-cardiac, non-morbidly obese surgery.
Intraoperative hypotension occurs often and is associated with adverse patient outcomes such as stroke, myocardial infarction and renal injury. The aim of this study was to test the accuracy of a physiology-based machine-learning algorithm using continuous non-invasive measurement of the blood pressure waveform with the Nexfin® finger cuff during surgery.
The purpose of this study is to evaluate the performance of a novel closed-loop (automated) vasopressor administration system that delivers norepinephrine using feedback from standard operating room hemodynamic monitor (EV1000 Monitor-Flotrac or Clearsight system, Edwards Lifesciences, IRVINE, USA).
In this prospective observational study investigators aim to seek for any possible correlation between the venous to arterial carbon dioxide difference (pCO2 gap) at the end of surgery and the percentage of time spent above a predefined threshold of stroke volume (SV) andn mean arterial pressure (MAP).
Prospective, randomized and controlled study who will be conducted at Maisonneuve-Rosemont hospital with the following objectives: To determine if an infusion of carbetocin over 10 minutes will reduce hemodynamic side effects, especially the peak of heart rate, in comparison to a rapid intravenous bolus (less than 2 seconds). To determine if an infusion of carbetocin will reduce the other side effects of duratocin in comparison to a rapid intravenous bolus. Study plans to enroll 70 adult patients scheduled to undergo elective cesarean delivery under spinal anesthesia. Half of the patient will receive Carbetocin 100 mcg intravenous as a bolus (less than 2 seconds) and the other half will receive Carbetocin 100 mcg intravenous infusion over 10 minutes.
The study aim is to investigate if preoperative volume bolus based on lean body weight could preserve mean arterial pressure during target controlled infusion of anaesthesia (TCI) or rapid sequence induction of anaesthesia (RSI) in non-cardiac, non-morbidly obese surgery.
Traditional methods for intravascular volume status assessment include physical examination, raised leg test, central venous pressure (CVP) and pulmonary artery catheters occlusion pressure (PAWP). Central venous pressure and pulmonary artery occlusion pressure are invasive and associated with significant complications. More recently, a number of less invasive techniques have been introduced, but they lack standardization and reliability. Ultrasonically, inferior vena cava collapsibility can detect hypovolemia non-invasively.
