OBJECTIVE The present study was conducted to compare the effect of clonidine and gabapentin premedication in modifying the hyperdynamic response following laryngoscopy and tracheal intubation. METHODS AND MATERIALS Seventy-five ASA I-II patients of both sexes (37 males (49.3%), 38 females (50.7%)) 18 to 45 years (mean 32.8 +/- 8.65 yr.) were randomly allocated into three equal groups (25 each...

BACKGROUND Rapid tracheal intubation with rocuronium has not been studied using a probability-based approach. The authors aimed to predict doses of rocuronium giving 90% and 95% probability of in intubation within 60 s and to estimate their durations of action. METHODS After premedication with midazolam, 2 mg, anesthesia was induced in 80 subjects with fentanyl, 2 microg/kg, followed 3 min la...

n a recent review article on spinal anesthesia for cesarean section (l), Kestin recommended the use I of subarachnoid anesthesia if epidural block was inadequate after the administration of the maximum allowable dose of local anesthetic (2). The use of spinal anesthesia in obstetrics has also been advocated for patients with potentially difficult airways, as this approach usually would obviate ...

BACKGROUND AND OBJECTIVES Laryngoscopy and intubation can cause hemodynamic response. Various medications may be employed to control that response. In this study, we aimed to compare the effects of dexmedetomidine, fentanyl and esmolol on hemodynamic response. METHOD Ninety elective surgery patients who needed endotracheal intubation who were in American Society of Anesthesiology I-II group a...

The aim of this study was to evaluate the effect of age on the hemodynamic responses to intravenous (IV) ephedrine in pediatric patients anesthetized with halothane, nitrous oxide, and oxygen. One hundred ten pediatric patients, ranging in age from 0.1 to 15 yr, were assigned to receive 0.1 mg/kg (n = 55) or 0.2 mg/kg (n = 55) IV ephedrine. General anesthesia was maintained with 1.0 minimum alv...

Performing emergency endotracheal intubation necessarily means doing so under less than ideal conditions. Rates of first-time success will be lower than endotracheal intubation performed under controlled conditions in the operating room. Some factors associated with improved success are predictable and can be modified to improve outcome. Factors to be discussed include the initial decision to p...

A retropharyngeal abscess is an infection in one of the deep spaces of the neck. An abscess in this location is an immediate life-threatening emergency with potential for airway compromise and other catastrophic complications . In adults, retropharyngeal abscess can occur as a result of local trauma such as foreign body ingestion like fishbones or instrumental procedures like laryngoscopy, endo...

BACKGROUND During shoulder surgery, blood pressure is frequently measured at the ankle. Anesthetic complications may result when ankle blood pressure is higher than brachial blood pressure and anesthesiologists misinterpret ankle blood pressure as brachial blood pressure. Therefore, we investigated whether ankle blood pressure is significantly higher than brachial blood pressure before anesthes...

INTRODUCTION Success rates with emergent endotracheal intubation (ETI) improve with increasing provider experience. Few objective metrics exist to quantify differences in ETI technique between providers of various skill levels. We tested the feasibility of using motion capture videography to quantify variability in the motions of the left hand and the laryngoscope in providers with various expe...

1. The position of the patient during laryngoscopy is an important factor determining the success of endotracheal intubation. In the present study, the authors have not specified the position of the obese patients while attempting laryngoscopy and endotracheal intubation. The use of ramped position has shown to improve the laryngoscopic view and intubation success rate in comparison to the stan...
