the laryngeal mask airway (lma) is an important addition to the anesthetist's equipments. however, its usage may involve some complications. we have encountered an unusual and potentially serious complication using this equipment. a 45-year old man underwent cataract surgery under general anesthesia. after the induction of anesthesia, a size 4 of the reusable classic lma was inserted without an...
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...
treacher collin’s syndrome (tcs) is a rare inherited condition characterized by bilateral and symmetric abnormalities of structures within the first and second bronchial arches. patients with tcs present a serious problem to anesthetists maintaining their airway as upper airway obstruction and difficult tracheal intubation due to severe facial deformity. because of retrognathia, airway manageme...
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...
Background and purpose: control of intraocular pressure has specific role in ophthalmic surgery but ËTT as a common access to airway in general anesthesia lead to increase in ÏÔP, so, many study have been done to evaluate an alternative access to airway such as laryngeal mask. We conducted this study to evaluate intraocular pressure changes subsequent to insertion of laryngeal mask airway and...
results sore throat was recorded in 32.9% of patients with lma and 44.2% of intubated patients, but it was not statistically significant (fisher’s exact test = 0.158). hoarseness was recorded in 3.5% of patients with lma and 24.4% of intubated patients (fisher’s exact test = 0.000). in 1.2% of patients with lma cough was recorded; it was also seen in 7% of the intubated patients (fisher’s exact...
background: various studies are seeking to find new methods to improve techniques of laryngeal mask airway (lma) insertion and reduce possible complications. in this study, we embarked on a clinical study to investigate the advantages of a new insertion method of laryngeal mask and to compare it with the classic method. materials and methods: two hundred patients aged 20-60 years old in 2012 we...
Aims and background: Airway management is one of the key skills in managing and treating of critical patients. In hospital departments before reaching an anesthesiologist or experienced team, this task lies with the nurses who have not been trained enough in this field. This study was conducted to evaluate the ability of nurses before and after a manikin-based workshop for securing the airway ...
Background and Aim: The purpose of this study was to compare the effect of thiopental sodium-midazolam combination on the stress response and hemodynamic changes between tracheal intubation and laryngeal mask airway insertion during airway management. Materials and Methods: In this clinical trial study, 70 patients ASA 1, 2 candidates for elective surgery were randomly divided into two groups o...
post-operative sore throat is one of the most common complications and complaints of patients after general anesthesia especially in operations that need endotracheal intubations. its causes are: size of endotracheal tube and type of its cuff, inadequate airway humidification, trauma during intubation and suctioning, high flow of inspiratory gases, surgical manipulation of airway and adjacent o...
