background: to determine if the glidescope® videolaryngoscope (gvl) could attenuate the hemodynamic responses to orotracheal intubation compared with conventional macintosh laryngoscope. objectives: the aim of this relatively large randomized trial was to compare the hemodynamic stress responses during laryngoscopy and tracheal intubation using gvl versus mcl amongst healthy adult individuals r...
Angiotensin II (Ang II) and atrial natriuretic factor (ANF) appear to act as functional antagonists in the regulation of fluid and electrolyte homeostasis and blood pressure. To further define the relations between these hormones in vivo, we investigated the effect of low doses ofAng II (1-10 ng/kg/min) on plasma ANF levels. We also evaluated the influence ofANF release on the renal and hormona...
Background: Tracheal intubation and direct laryngoscopy are powerful noxious stimuli that can elicit sever hemodynamic responses. These hemodynamic responses should be attenuated by appropriate use of premedication, smooth induction of anesthesia and rapid tracheal intubation. Gabapentin and pregabalin have been suggested in several studies to be efficient. Gabapentin is an antiepileptic drug a...
conclusions fentanyl and fentanyl plus lidocaine effectively decreased the hemodynamic response to tracheal intubation, however, neither fentanyl nor fentanyl plus lidocaine, could inhibit all hemodynamic responses, moreover fentanyl plus lidocaine was not more effective than fentanyl alone. background induction of anesthesia and endotracheal intubation often creates a period of hemodynamic ins...
Background & Aim: Clonidine, an alpha 2 agonist, attenuates sympathetic responses during general anesthesia and improves the intra-operative hemodynamic stability. In this randomized double blinded clinical trial study, we report the effects of 300µg oral clonidine premedication(n=22) or placebo(n=22) on hemodynamic alteration during gynecologic laparoscopic surgery, under general anesthesi...
conclusions there were no statistical differences between oral clonidine and intravenous lidocaine regarding attenuation of hemodynamic responses after tracheal intubation in controlled hypertensive patients, although the rate of complications including mouth dryness, bradycardia, and orthostatic hypotension was significantly higher in the clonidine group before induction of anesthesia. results...
Introduction: Laryngoscopy and tracheal intubation necessitate to start a surgery and induction of general anesthesia as well as the maintenance of the air way and to provide ventilation. However, Laryngoscopy and tracheal intubation may lead to hemodynamic response that appear with the symptoms of hypertension tachycardia, arrhythmia and myocardial ischemia and results in myocardial infarction...
Hemodynamic effects of vasodilator therapy (phentolamine or nitroprusside) were studied in 38 patients with acute myocardial infarction (AMI). Cardiac metabolism was studied in 19 of the 38 patients. According to the initial level of left ventricular filling pressure (LVFP) and left ventricular stroke work index (SWI), patients were divided into three groups: Group I-nine patients with LVFP 15 ...
background there have been many concerns about alteration in hemodynamic parameters within and shortly after endotracheal intubation (eti) in patients scheduled for elective coronary artery bypass grafting (cabg). objectives we compared the attenuation effect of magnesium sulfate and lidocaine on hemodynamic responses after eti, in patients undergoing cabg. patients and methods in this randomiz...
