Inhalational insulin was withdrawn from the market due to its potential to produce airway hyper-reactivity and bronchoconstriction. So the present study was designed to explore the acute effects of insulin on airway reactivity of guinea pigs and protective effects of salbutamol and beclomethasone against insulin induced airway hyper-responsiveness on isolated tracheal smooth muscle of guinea pi...

Airway management of patients with tracheal stenosis is highly challenging and even establishing a surgical airway may be difficult in these patients. A 24 year old female developed pinhole restenosis after undergoing web resection reconstruction. After other modes ventilation had failed, we used the Manual jet ventilator endotracheal tube assembly as rescue device performed intermittent low-fr...

background the forced oscillation technique (fot) is a non-invasive means of measuring respiratory resistance and reactance. we tested our hypothesis that endotracheal intubation would cause more substantial preoperative increases in fot parameters than a supraglottic airway device (sgd). methods forty patients requiring general anesthesia and mechanical ventilation for transurethral bladder tu...

background: extubation is associated with the risk of complications such as accumulated secretion above the endotracheal tube cuff, eventual atelectasia following a reduction in pulmonary volumes because of a lack of physiological positive end expiratory pressure, and intra-tracheal suction. in order to reduce these complications, and, based on basic physiological principles, a new practical ex...

introduction adenotonsillar hypertrophy is a common disorder among children which, without proper treatment, may lead to considerable problems. although the consequences of this disorder have been studied in other articles, we decided to evaluate the changes in pulmonary function tests in these children after adenotonsillectomy, and the correlation between clinical and spirometric parameters.  ...

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...

abstract background: clearing the endotracheal tube through suctioning should be done to promote oxygenation. depth of suctioning is one of the variables in this regard. in shallow suctioning method, the catheter passes to the tip of the endotracheal tube, and in deep suctioning method, it passes beyond the tip into the trachea or brunches. this study aimed to evaluate the effect of shallow and...
