Graded hypercapnia and cerebral autoregulation during sevoflurane or propofol anesthesia.
BACKGROUND Hypercapnia abolishes cerebral autoregulation, but little is known about the interaction between hypercapnia and autoregulation during general anesthesia. With normocapnia, sevoflurane (up to 1.5 minimum alveolar concentration) and propofol do not impair cerebral autoregulation. This study aimed to document the level of hypercapnia required to impair cerebral autoregulation during pr...
متن کاملHemodynamic differences in sevoflurane versus propofol anesthesia.
The aim of the study was to compare the effect of sevoflurane and propofol anesthesia on myocardial contractility during laparotomic cholecystectomy using transesophageal echo-Doppler. In the study, 40 patients were randomized into two groups, depending on whether they received sevoflurane or propofol anesthesia. Heart rate, cardiac index, stroke volume, left ventricular ejection time and accel...
متن کاملHemodynamic Stability during Induction of Anesthesia in ElderlyPatients: Propofol + Ketamine versus Propofol + Etomidate.
INTRODUCTION Various methods have been recommended to prevent hemodynamic instability caused by propofol induction. Current study evaluates hemodynamic effects of ketamine and propofol in comparison to etomidate and propofol during anesthesia induction. METHODS Sixty-two patients over 50 years old undergoing elective surgeries were randomly assigned to ketamine + propofol (ketofol) (n=30) and...
متن کاملHemodynamic changes following the administration of propofol to facilitate endotracheal intubation during sevoflurane anesthesia.
BACKGROUND The common intravenous anesthetic agent, propofol, is frequently reported to have negative inotropic and chronotropic effects. In the pediatric population, propofol is commonly used after inhalation induction to facilitate endotracheal intubation without the need for a neuromuscular blocking drug agent. In this setting, we have noted that propofol administration is commonly followed ...
متن کاملEvaluation of Mexiletine Effect on Bispectral Index Changes and Hemodynamic Responses to Endotracheal Intubation and During General Anesthesia
Background &Objective: Plaryngoscopy and tracheal intubation increase not only blood pressure and heart rate but also Bispectral Index (BIS) of the patients. In this study, hemodynamic and BIS changes were surveyed after tracheal intubation and during general anesthesia followed by mexiletine prescription . Materials & Methods: In this study, 50 patients aged between 20 and 60 who were ca...
