BACKGROUND The liver is the most commonly injured organ in blunt abdominal trauma. Although major hepatic bleeding may be partially controlled with portal triade clamping (the Pringle's maneuver), continuous prolonged clamping results in liver ischemia. OBJECTIVES The purpose of this study was to determine the safe time of Pringle maneuver based on pathologic changes of liver in rabbit models...

BACKGROUND Nasal valve collapse is a common cause of nasal obstruction in otolaryngology practice. Common examination methods, such as the Cottle Maneuver and modified Cottle Maneuver are available. However, these methods are dichotomous and do not provide ordinal severity information. The Ottawa Valve Collapse Scale (OVCS) is a grading system for assessing and easily grading external nasal val...

A 17-year-old woman had undergone exploratory laparotomy because of a huge cystic pelviabdominal mass equivalent of 36 weeks' gestation. A closed system drainage maneuver was applied via using a laparoscopic trocar to drain a revealed large left paraovarian cyst. This maneuver was found to be a simple and effective method to safely aspirate giant paraovarian cysts; thus allowing their total exc...

Recent changes were introduced in acute hypoxemic respiratory failure children ventilation methods. There are evidences that less aggressive ventilation strategies can improve severe pulmonary injury survival. Experimental trials evidenced a relationship between inappropriate ventilatory measures and delayed acute pulmonary injury improvement, or even worsening. From this, a protective ventilat...

OBJECTIVES/HYPOTHESIS Using network meta-analysis, we aimed to compare the efficacy and safety of Epley and Semont maneuvers as treatment options for posterior canal benign paroxysmal positional vertigo. STUDY DESIGN Network meta-analysis. METHODS Randomized controlled studies with a Jadad score ≥ 3 that used an Epley or Semont maneuver in posterior canal benign paroxysmal positional vertig...

BACKGROUND AND OBJECTIVES Sellick described the importance of applying pressure in the cricoid cartilage during anesthesia induction to prevent regurgitation of gastric contents. Since then, the maneuver has been widely accepted by anesthesiologists as a fundamental step during induction with the rapid sequence technique. The objective of the present report was to discuss the indications, techn...

Arterial pulse pressure response during the strain phase of the Valsalva maneuver has been proposed as a clinical tool for the diagnosis of left heart failure, whereas responses of subjects with preserved systolic function have been poorly documented. We studied the relationship between the aortic pulse amplitude ratio (i.e., minimum/maximum pulse pressure) during the strain phase of the Valsal...

A passive decomposition framework for the formation and maneuver controls for multiple rigid bodies is proposed. In this approach, the group dynamics of the multiple agents are decomposed into two decoupled systems: the shape system representing internal group formation shape (formation, in short), and the locked system abstracting the overall group maneuver as a whole (maneuver, in short). The...

Tracking maneuvering targets presents a great challenge to airborne surveillance radar signal processing and sensor systems management systems. Smears caused by an uncompensated maneuver (either translational or rotational) affect target identification (ID) with distorted target images. An unexpected maneuver introduces large position estimation errors to a tracker and in the worst case loss of...

Satellites in a formation might need to maneuver to avoid potential collisions that may occur when foreign objects enter the formation, or when a satellite within the formation drifts into the path of another. In either case we seek to determine the probability of a future collision based on current state knowledge and the uncertain dynamic environment, and further to determine a control strate...
