Hemorrhage control during surgery remains a major clinical challenge for surgeons. Bleeding can affect the safety and efficacy of any surgical procedure. There are well-established methods to address this side-effect of surgery, but all current technologies require the surgeon to direct attention to hemostasis rather than the continuance of the procedure. We have developed a novel surgical meth...

OBJECTIVE Ultrasound-guided needle localization has been used prior to the surgical excision of nonpalpable breast lesions. The aim of the study was to assess the feasibility of the use of a saline immersion specimen ultrasound technique (immersion-US) to confirm the successful removal of breast lesions. MATERIALS AND METHODS The devised immersion-US technique was used to examine the excised ...

INTRODUCTION Near-drowning incidents and drowning deaths after accidental immersion in open waters have been linked to cold shock response. It consists of inspiratory gasps, hyperventilation, tachycardia, and hypertension in the first 2-3 min of cold-water immersion. This study explored the immediate changes in cerebral blood flow velocity (Vmean) during cold-water immersion since cold shock in...

This study evaluated color stability, surface roughness and flexural strength of acrylic resin specimens after immersion in alkaline peroxide and alkaline hypochlorite, simulating a period of one and a half year of use of overnight immersion. Sixty disc-shaped (16x4 mm) and 80 rectangular specimens (65x10x3.3 mm) were prepared from heat-polymerized acrylic resin (Lucitone 550) and distributed i...

Eleven anesthetized rhesus monkeys were used to study cardiovascular, renal, and endocrine alterations associated with 120 min of head-out water immersion. Five animals underwent complete intrapericardial denervation using the Randall technique, while the remaining six monkeys served as intact controls. Each animal was chronically instrumented with an electromagnetic flow probe on the ascending...

BACKGROUND Reflex excitability is increased in hemiplegic patients compared to healthy controls. One challenge of stroke rehabilitation is to decrease the effects of hyperreflexia, which may be possible with water immersion. Methods/Aims: The present study examined the effects of acute water immersion on electrically-evoked Hmax:Mmax ratios (a measure of reflex excitability) in 7 hyperreflexive...
