Background: Epidural fibrosis (EF) is a part of normal physiological tissue response to laminectomy and it may be an important cause of failed back surgery syndrome (FBSS). The objective of this study was to evaluate the effect of using gel foam after laminectomy on reduction of epidural fibrosis. Methods: In this prospective study forty five rabbits were recruited. The cases undergone bilater...

Acute head trauma is one of the most common causes of emergency hospital admissions and its two important complications are subdural haematomas and epidural haematomas, for which the CT scan is a main tool of diagnosis. Differentiation of this two haematoms is important and the ability of CT scan to differentiate them always been in question. This descriptive study aims to evaluate the ability ...

ABSTRACT The effect of position on the spread and the onset time of epidural anesthesia has not been well documented. This study is undertaken to assess the effect of modified trendelenburg position on the spread of epidural anesthesia for cesarean section. 739 parturients were undergone epidural anesthesia for elective or emergent sesarean section. They were divided into 2 groups in a...

تحریک الکتریکی نخاع خرگوش با چند الکترود تحریک و شکل موجهای مختلف تحریک در این رساله بررسی و آزمایش شده است . تحریک الکتریکی نخاع خرگوش به منظور ایجاد انقباض ایزومتریک کنترل شده در عضلات پای حیوان صورت گرفته است . برای ایجاد انقباض ایزومتریک در پاب حیوان از چند الکترود تحریک با آرایشهای مختلف تحریک و شکل موجهای مختلف تحریک با تحریک سطحی و اپیدورال استفاده کرده ایم. در آزمایشهای تحریک الکتریکی ن...

سابقه و هدف: با توجه به اهمیت ایجاد بی دردی و عوارض کمتر بعد از عمل جراحی و با توجه به گزارش های متعدد و گاهی متناقض در مورد تاثیر اضافه کردن فنتانیل و به منظور مقایسه تاثیر مورفین اپیدورال با فنتانیل و بدون فنتانیل، این تحقیق روی بیماران تحت عمل توراکوتومی بیمارستان مسیح دانشوری انجام گرفت. مواد و روش ها:تحقیق به روش کارآزمایی بالینی دوسوکور بر روی تعداد 74 بیمار صورت پذیرفت و موارد منع مصرف د...

    Spontaneous spinal epidural hematoma is an uncommon but devastating problem. Rapid diagnosis and immediate intervention are essential because any delay in diagnosis could increase mortality and morbidity.   Our case was a 56 years old man presented by pain in interscapular area and neck that rapidly progressed to lower extremity weakness and urinary retention. The patient had history of pro...

Background: Thoracotomy is a particularly painful surgery and good pain control is crucial to maximize the ability to cough and breath. The most common methods of post operative pain management are systemic narcotics and epidural adminstration of local anesthetic agents or narcotics. The purpose of the persent study was to compare postthoracotomy analgesia of extraplural and epidural catheters....

Background and aimsNarcotics are commonly used in controlling of the postoperative pain. But few studies are available about direct narcotic spillage into surgical field. The aim of this study was to check the efficacy of this method for analgesia in postoperative lumbar microdiscectomy.MethodsIn a randomized clinical trial, numbers of 100 patients were included into two equal groups due to low...

    Background & Aim: Epidural anesthesia is one of the anesthethic techniques for cesarean section. However, epidural anesthesia with lidocaine has some disadvantages such as delayed onset of action and short duration of analgesia. The goal of this study is to evaluate maternal sensory and motor blockade, neonatal Apgar score, and side effects of adding 50 and 100 mg tramadol to 2% lidocaine i...
