PURPOSE The disadvantages of intravenous regional anesthesia (IVRA) include slow onset, poor muscle relaxation, tourniquet pain, and rapid onset of pain after tourniquet deflation. In this randomized, double-blind study, we evaluated the effect of nitroglycerin (NTG) in quality improvement when added to lidocaine in IVRA. METHODS Forty-six patients (20-50 yrs), were randomly allocated in two ...

OBJECTIVE The purpose of this study was to determine if emergency tourniquet use saved lives. SUMMARY BACKGROUND DATA Tourniquets have been proposed as lifesaving devices in the current war and are now issued to all soldiers. Few studies, however, describe their actual use in combat casualties. METHODS A prospective survey of injured who required tourniquets was performed over 7 months in 2...

INTRODUCTION Women with fibromyalgia (FM) have symptoms of increased muscular fatigue and reduced exercise tolerance, which may be associated with alterations in muscle microcirculation and oxygen metabolism. This study used near-infrared diffuse optical spectroscopies to noninvasively evaluate muscle blood flow, blood oxygenation and oxygen metabolism during leg fatiguing exercise and during a...

background untrained fingertip palpation has been shown to be unable to adjust endotracheal tube (et) cuff pressure in most intubated patients. objective we determined the impact of a training course of ett cuff adjustment by palpation in attaining a safe cuff inflation pressure. patients and methods twenty-five nurses were asked to adjust the ett cuff pressure to 25 cmh2o by palpation on three...

engue is epidemic or endemic in virtually every country in the tropics; it is even cited in the Guinness World Records, 2002, as the world's most important viral hemorrhagic fever and the most geographically widespread of the arthropodborne viruses. As illustrated in this issue of Emerging Infectious Diseases, dengue epidemics are expanding rapidly, as is the literature on the subject. That den...

Experimental results presented at a previous meeting (Gilliatt, Fowler, and Ochoa, 1972) threw doubt on the classic concept that acute pressure lesions of peripheral nerves are due to obliteration of the neural blood supply, and thus to ischaemia of nerve fibers. Using a cuff inflated to 1000 mm Hg round· the leg of the baboon for 1 to 2 hours, it had been found that the anatomical lesions were...

BACKGROUND Current evidence shows that anaesthetic digital block with epinephrine is safe in surgical selected patients. There are no controlled studies that have examined the efficacy of local anaesthesia with vasoconstrictor in chemical matricectomy without using tourniquet to control bleeding. OBJECTIVES A controlled, prospective and randomized study was conducted to examine primarily the ...

Background: Successful repair of a torn rotator cuff may prevent progression to rotator cuff arthropathy. However,previous studies have shown a substantial rate of failure after rotator cuff repair and characteristics of surgicallyrepaired rotator cuffs that go on to shoulder arthroplasty have not been fully elucidated. The purpose of this study wasto determine the patient cha...
