OBJECTIVES Corticosteroids are frequently used in a range of otorhinolaryngologic conditions due to their anti-inflammatory and antiedematous properties. In this meta-analysis, we aimed to assess the role of preoperative steroids for attenuating intraoperative bleeding during endoscopic sinus surgery among patients with nasal polyps. DATA SOURCES PubMed, SCOPUS, EMBASE, the Web of Science, an...

BACKGROUND The aim of study was to evaluate the effect of mechanical ventilation mode type, pressure-controlled ventilation (PCV), or volume-controlled ventilation (VCV) on intra- and postoperative surgical bleeding in patients undergoing posterior lumbar interbody fusion (PLIF) surgery. METHODS This was a prospective, randomized, single-blinded, and parallel study that included 56 patients u...

purpose : to evaluate efficacy, complications, and patient satisfaction using local anesthesia (la), in comparison to with general anesthesia (ga) in external dacryocystorhinostomy (dcr) methods : in this prospective study, 149 patients with complete nasolacrimal duct (nld) obstruction who were candidates for external dcr were randomized in 2 groups: ga 73 patients, and la 76 patients. intraope...

BACKGROUND One of the major problems in surgery is intraoperative bleeding which reduces visibility in the operative field. An important task for an anesthetist during head and neck surgery is to improve intraoperative visibility. OBJECTIVES The purpose of this study was to compare the amount of bleeding using different doses of oral metoprolol during three common types of nasal operation; rh...

HYPOTHESIS Bovine pericardium (BP) demonstrates improved intraoperative hemostasis and equivalent perioperative morbidity compared with Dacron when used as patch material for angioplasty following carotid endarterectomy. OBJECTIVE To prospectively compare BP and Dacron patch angioplasty after carotid endarterectomy in a randomized fashion. METHODS Ninety-five consecutive primary carotid end...

juvenile nasopharyngeal angiofibroma (jna) is a rare, benign and locally invasive tumor. massive bleeding because of vascularity of tumor and postoperative recurrence are potential problems of management. endonasal approach reduces the rate of postoperative recurrence, intraoperative bleeding, and complications of surgery, time of operation and duration of hospitalization. in this article, we r...

extensive blood loss in total hip surgery is well known and is associated with a high transfusion rate of allogeneic blood. the aim of this study is to assess the effects of intraoperative tranexamic acid on post-operative bleeding and need for allogeneic transfusion during hip fracture surgery. we investigated 67 patients undergoing hip fracture surgery in a prospective, randomized, double-bli...
