laryngeal mask is a supraglothic instrument for ventilation of patients who are under anesthesia. insertion of laryngeal mask requires maintaining sufficient depth of anesthesia to avoid airway reflex (gagging, coughing and spasms). the present study investigated two techniques of anesthesia with propofol-atracurium and thiopental-atracurium to facilitate insertion of the laryngeal mask, term o...
Introduction: With the increasing severity of the COVID-19 epidemic, wearing a mask was recommended. This recommendation seems to have created concern among the public. Wearing a mask generally reduces the risk of virus and therefore potentially saves lives. In healthy populations, wearing a mask does not appear to cause any harmful physiological changes, and the potentially life-saving benefit...
Aims and background: The difficulty of ventilation with masks is one of the most common causes of severe respiratory consequences in the field of anesthesia. Objective: To evaluate the effect of patient position, voice production and neck rejection on the Mallamapati grade, in order to predict the difficulty of ventilation with mask in patients. Materials and Methods: This research was of a pr...
background: despite the widespread use of respiratory protection equipment in different jobs, the effects of these devices on people’s physiological responses are not well recognized as yet. therefore, the aim of this study is to evaluate the effect of the air purifying respiratory protection equipment on the heart rate. methods: this experimental study was performed in a climate chamber under ...
This research project is a field study to investigate the complications of general anaesthesia with mask in patients under surgery in a hospital affiliated to University of Medical Sciences Iran. The specific goals of this study are as follows: -To determine some of the characters of patients under study. -To determine the complications of general anesthesia with mask during surgery in on...
Background and Objective: In this research, the goal is to identify the decision-making styles of mask customers based on the proposed styles Spurs and Kendall. The question that arises in this research is that decision-making styles What are the mask clients like in coronary heart disease? Method: This research is applied in nature and is descriptive and analytical in terms of implementation. ...

This paper proposes a novel method for document enhancement. The method is based on the combination of two state-of-the-art filters through the construction of a mask. The mask is applied to a TV (Total Variation) regularized image where background noise has been reduced. The masked image is then filtered by NLmeans (Non Local Means) which reduces the noise in the text areas located by the mask...
Back ground & Aims: In the edentulous patients some authors suggest to leave dentures in when ventilating with bag-mask. In this research, we suggest a more efficient method. Materials & Methods: In the prospective blind randomized clinical trial we included 200 patients (age≥55) into two groups. After induction of anesthesia in all groups, in the group I, we placed folded gauze in each bucca...
Aim and background: Tracheal intubation remains the choice method for keeping airways open during mechanical ventilation. Among the various methods, standard method of direct laryngoscopy generally used by non-skilled staff increases the risk of failure. This study was performed to evaluate and compare the results of tracheal intubation using laryngeal masks vs. glidescope led by novice personn...
