Filter by:In this study, it was aimed to compare the effects of three different PEEP levels (0-4, 5-8, 9-12 cmH2O) on intraabdominal pressure and hemodynamic parameters of patients in intensive care unit.
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.
during cardiopulmonary resuscitation, an important element of the procedure is to achieve optimal organ perfusion. For this purpose, high quality chest compressions is one of the basic elements of the procedure. however, similarly as in the case of hypovolemic shock, elevation of the lower limbs may be helpful. The study is a randomized cross-over study and includes the effect of lower limb elevation on hemodynamic parameters in healthy participants.
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.
The present study aims to compare the hemodynamic response during laryngoscopy and orotracheal intubation using continuous infusion of lidocaine and esmolol in patients undergoing general anesthesia.
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.
To monitor the changes in central and peripheral monitors/waveforms during gradual hypovolemia induced by lower body negative pressure in healthy volunteers.
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).
