context a tourniquet is a device that is used frequently in most orthopaedic surgeries but this routine device can lead to serious complications so we decided to review and declare it for safe instruction and use. evidence acquisition we searched the word “tourniquet” in pubmed and google and reviewed all full text english articles and abstracts of non-english articles. in addition, we read all...

abstract background: today, the rate of surgeries is increasing, but surgeries are canceled due to various reasons. unexpected cancellation of surgeries not only results in disorder in the operating room schedule, but also causes stress for patients and their family and increases costs. we determined the number and causes of surgery cancellations and areas for improvement. materials and methods...

the aim of this study is to find causes of cardiac disrhytmias during ophthalmic surgeries in patients under general anesthesia with no history of heart disease in iran’s educational hospitals. this was a univarient study. a sample of 250 patients selected randomly. data were gathered by four resources: interview, patient’s documents, kind of treatment selected by anesthesiologist and monitorin...

Sir,?I am with you all the way in the suggestion for establishment of Central Surgeries made in your article last month on " The Organisation of Panel Practice," and believe this to be one of the lines on which general practice must develop if it is to keep abreast of the advances of science. My experience at the out-patient department of a large general hospital during the war brought home to ...

We show that all exceptional surgeries on hyperbolic alternating knots in the 3-sphere are integral surgeries.

It is shown that a hyperbolic knot in the 3-sphere admits at most nine integral surgeries yielding 3-manifolds which are reducible or whose fundamental groups are not infinite word-hyperbolic.

We use the Ozsváth-Szabó contact invariants to distinguish between tight contact structures obtained by Legendrian surgeries on stabilized Legendrian links in tight contact 3-manifolds. We also discuss the implication of our result on the tight contact structures on the Brieskorn homology spheres −Σ(2, 3, 6n − 1).

INTRODUCTION The purpose of this article was to provide the literature regarding the psychological stress in the peri-operative period of adult patients undergoing operations under general anesthesia. METHODS The articles were obtained by surveying the papers published and catalogued in the Medline Pubmed interface database, Lilacs and the Biblioteca Virtual de Saúde (BVS) since 1984, crossin...
