BACKGROUND Dexmedetomidine is an alpha-2 adrenergic agonist with sedative, anxiolytic, and analgesic properties. This study was designed to evaluate the inhibitory effects of preoperative administration of 0.5 µg/kg dexmedetomidine on hemodynamic responses caused by endotracheal intubation in elderly patients undergoing treatment for hypertension. METHODS Forty elderly (≥ 65 years old) patien...

INTRODUCTION Sufficient ventilation and oxygenation through proper airway management is essential in patients undergoing cardio-pulmonary resuscitation (CPR). Although widely discussed, securing the airway using an endotracheal tube is considered the standard of care. Endotracheal intubation may be challenging and causes prolonged interruption of chest compressions. Videolaryngoscopes have been...

BACKGROUND This prospective, randomized, single blind, single operator study was conducted to compare hemodynamic responses when endotracheal intubation was performed using the Bonfils intubation fibrescope versus the C-MAC videolaryngoscope. METHOD Forty-four ASA I patients aged between 18 and 60 years, scheduled for elective surgery requiring endotracheal intubation were recruited. They wer...

BACKGROUND The hemodynamic responses to endotracheal intubation are associated with sympathoadrenal activity. Polymorphisms in the beta1-adrenergic receptor (β(1)AR) gene can alter the pathophysiology of specific diseases. The aim of this study is to investigate whether the Ser49Gly and Arg389Gly polymorphism of the β(1)AR gene have different cardiovascular responses during endotracheal intubat...

Although bedside ultrasonography can accurately distinguish esophageal from tracheal intubation, it is not used to establish the correct depth of endotracheal tube insertion. As indirect sonographic markers of endotracheal tube insertion depth have proven unreliable, a method for visual verification of correct tube depth would be ideal. We describe the use of saline to inflate the endotracheal ...
