Background & Aim: One of the most important points in the pharmacology of Anesthetic drugs is the their effect on the depth anesthesia and for its assessment recently an important marker BIS is used. In this study we evaluated the effect of three drugs namely Halothane, Isoflurane and Sevoflurane on depth of anesthesia using BIS monitoring. Patients and Methods: This study was performed on ...
objectives this study aimed to examine the relationship between patients’ anthropometric characteristics and depth of spinal needle insertion to the subarachnoid cavity. patients and methods 385 patients with asa class i – ii, aged 18 - 65 years and undergoing elective surgery of the lower abdomen and extremities under spinal anesthesia, were selected for this cross-sectional study. the patient...
textbooks play a crucial role in language learning classrooms. the problem is that among the great quantity of available textbooks on the market which one is appropriate for a specific classroom and a group of learners. in order to evaluate elt textbooks, theorists and writers have offered different kinds of evaluative frameworks based on a number of principles and criteria. this study evaluate...
melatonin, a pineal gland secreted hormone has different effects on mammalian physiology. recently, specific receptors of melatonine have been found in the central nervous system and spinal cord of rabbits. l - theanine is a unique amino acid in the tea plant ( camellia sinensis ). the effects of this amino acid is based on increasing gaba and dopamine levels in the brain and has a weak effect ...
Monitoring of depth of anesthesia is an ongoing problem in anesthesia. In this paper, using SEF, BDR, BTR parameters which is calculated by power spectral density. EEG data were obtained from 7 patients (ASA I, II) during general anesthesia with sevoflurane. The anesthetic depth evaluation index algorism was embodied to obtain a quantified index with the scale of 0~100. Then quantified index co...
apart from other aspects, desert is a natural environment and is one of the appealing terrestrial elements. putting its symbolic and fictional senses aside, the term “desert” bears mystic sense more than material sense. in addition to the worlds materialistic experiences, desert has attracted the attention of writers because it creates a kind of inner experience, which returns the individual in...
the effect of quinpirol and sulpiride on the brain activity waves in conscious and aneasthetized rat
brain's waves are produced by spontaneous activity of neurons. these waves are changed by neurotransmitters in the central nervous system (cns). concentration of these neurotransmitters can be changed by various drugs and total power of brain waves also increase or decrease by these drugs. in this research effect of quinpirol and sulpiride on the brain waves was investigated. male wistar r...

Measuring the depth of anesthesia using electroencephalogram (EEG) is an important and challenging task. Although various methods using EEG have been proposed, these algorithms quantify the depth of anesthesia without any physiological models. In this paper, a method to quantify the depth of anesthesia as well as a signal model that describes the changes in EEG during anesthesia is presented. T...
