OBJECTIVE The Valsalva maneuver is recognized as an effective method to dilate the internal jugular vein (IJV). However, this maneuver cannot be performed in many cases, such as children and unconscious patients. The aim of this study was to evaluate the effectiveness of proximal IJV compression, which can easily be performed, regardless of patient cooperation. METHODS Healthy adult volunteer...

The impact of Lecompte’s maneuver on superior vena cava (SVC) has never been mentioned before. We think that in certain anatomical subsets, Lecompte’s maneuver can result in superior vena cava narrowing. We present a case report of patient with Tetralogy of Fallot with absent pulmonary valve with retro-aortic innominate vein who developed SVC thrombosis after Lecompte’s maneuver.

The objective of this paper is to derive a rapid turn-around maneuver for micro aerial vehicles flying in densely cluttered environments, in the form of variable altitude turns optimized for spatial constraints. The design results in a motion primitive which can be implemented on miniature aircraft at large. The primitive is tested on an MAV equipped with just yaw control and no roll control. T...

UNLABELLED The use of nasopharyngoscopy during the application of intrathoracic pressure (Müller maneuver) is frequently employed to establish the site of upper airway obstruction. The Müller maneuver, however, is used when the patient is awake and therefore may not correlate with obstruction occurring during sleep. AIM To compare the degree of pharyngeal obstruction in the retropalatal and r...

Selective inflow occlusion (SIO) maneuver preserved inflow of nontumorous liver and was supposed to protect liver function. This study aims to evaluate whether SIO maneuver is superior to Pringle maneuver in patients undergoing partial hepatectomy with large hepatocellular carcinomas (HCCs). Between January 2008 and May 2012, 656 patients underwent large HCC resections and were divided into 2 g...

INTRODUCTION Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral vestibular dysfunction. OBJECTIVE To assess whether the performance of the Dix-Hallpike maneuver after the Epley positioning maneuver has prognostic value in the evolution of unilateral ductolithiasis of posterior semicircular canal. METHODS A prospective cohort study in monitored patients at oto...

In this report, a brief history of the Valsalva (Valsalva-Weber) maneuver is outlined, followed by an explanation on the use of this approach for the evaluation of cardiac autonomic function based on underlying heart rate changes. The most important methodological and interpretative aspects of the Valsalva-Weber maneuver are critically updated, and some guidelines are established for simple app...
