Background: The Operation room personnel are exposed to anesthestic gases such as Isoflurane. The Chronic exposure to such substances will increase the risk of abortion as well as congenital malformations. In this research, we have determined the amount of exposure to isoflurane gas in operation room air and the breathing zone of operation room personnel. Methods: An analytical cross sectiona...
.مطالعه ای تئوری با استفاده از روش bmk و سری پایه aug-cc-pvtz روی سی مولکول شامل گاز نجیب به فرم ngr(ng= he, ne, ar, kr, xe r=ch3, cn, cch, bo, bnh, h, beo, auf)و fngr انجام شد. ساختار، انرژی تفکیک و پارامترهای اتم در مولکول(aim) ومرتبه پیوند طبیعی(nbo) برای همه ترکیبات به دست آمدند. مقادیر انرژی تفکیک نشان داد که همه ترکیبات غیر از farcn وfheh پایدار هستند و میزان پایداری آنها از he تا xe افزا...
OBJECTIVE The study is aimed to develop and assess the quality of an evaluation form used to evaluate the nurse anesthetic trainees' skills in undertaking a pre-use check of an anesthetic machine. MATERIAL AND METHOD An evaluation form comprising 25 items was developed, informed by the guidelines published by national anesthesiologist societies and refined to reflect the anesthetic machine us...
using the gaussian 2003 software and mp2/ 6–311 ++ g** method for he: he, ne:ne andmp2/6-31g method for ar: ar, kr: kr and hf/sto-3g method for xe: xe, the optimizedinteraction energies between two like atoms of rare gases (he, ne, ar, kr and xe) as a functionof the distances between the centers of two considered atoms were evaluated and the resultswere interpreted according to the lennard – jo...
Background & Aims: Tracheal intubation with a cuffed tube for the administration of general anesthesia is routine. The cuff of the endotracheal tube is inflated with air to achieve an adequate seal to prevent aspiration and leakage of air and anesthetic gases. Whereas over-inflation can decrease the mucosal perfusion, leading to pressure necrosis and nerve palsies. This study aimed to evaluate ...
Objective: The effects of anesthesia thechniques and drugs on different body systems and organs, especially immune system in elderly patients who underwent operation, have always been investigated by investigators The aim of this study was to compare the effects of general anesthesia with isoflurane or spinal anesthesia with lidocaine on oxidative and antioxidant indices. Materials & Methods: ...
