Background & Aims: Tracheal intubation with a cuffed tube for the administration of general anesthesia is routine. The cuff of the endotracheal tube is inflated with air to achieve an adequate seal to prevent aspiration and leakage of air and anesthetic gases. Whereas over-inflation can decrease the mucosal perfusion, leading to pressure necrosis and nerve palsies. This study aimed to evaluate ...
Objective: This study aims to compare the variables of plantar force, pressure and impulse during walking in men and women with flat feet. Methods: The study population consists of non-athlete students with and without flat feet. Of these, 48 (male and female) were selected as study samples. The peak pressure, force and impulse on the foot were measured during walking by a foot scanner at a sa...
Introduction: Changing position is one of the typical nursing care in intensive care units. This study aimed to investigate the effect of body positioning on intra-abdominal pressure and endotracheal tube cuff pressure and their relationship with each other in patients undergoing mechanical ventilation Materials and Methods: This was a before-after clinical trial study performed on 70 patients ...
Background: Standard prevention and treatment strategies to decrease peak plantar pressure include a total contact insert with a metatarsal pad, but no clear guidelines exist to determine optimal length of the pad with respect to the metatarsal head. The purpose of this study was to Check the appropriate length of metatarsal pad On the reduction of Diabetic foot ulcer mechanical parameters whil...
Introduction: The position estimation in gamma detection system will have constant misplacements which can be corrected in the calibration procedure. In the pixelated crystal uniformly irradiation of detector will produce irregular shape due to position estimation errors. This image is called flood field image and is used to calibrate the position estimation. In this work we pr...
BACKGROUND Thoracoscopic esophagectomy for esophageal cancer performed using two-lung ventilation in the prone position has many advantages, such as convenient anesthesia induction and maintenance, and good oxygenation. We examined the safety of surgery and anesthetic management by following chronological changes in intraoperative respiration and hemodynamics. METHODS We focused on the most r...
BACKGROUND There is no consensus on the precise rocker shoe outsole design that will optimally reduce plantar pressure in people with diabetes. This study aimed to understand how peak plantar pressure is influenced by systematically varying three design features which characterise a curved rocker shoe: apex angle, apex position and rocker angle. METHODS A total of 12 different rocker shoe des...
The Doppler echocardiographic characteristics of 70 prosthetic valves in 35 patients are reported. Twenty nine patients had a Björk-Shiley prosthesis in both mitral and tricuspid positions and six had Carpentier-Edwards valves in both sites. Five of the patients had abnormal tricuspid prostheses on the basis of clinical and echocardiographic criteria. Pulsed wave Doppler echocardiography was us...
