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...

Laryngeal haemangioma is commonly seen in children. Adult laryngeal haemangiomas are rare and usually involve the supraglottic region. Most common symptom includes dysphagia, dysphonia and shortness of breath. Detailed history, fiberoptic laryngoscopy and computerized scanning may suggest benign nature of the lesion but diagnosis is only confirmed by a biopsy. In comparison to infantile haemang...

Supraglottic airway devices (SADs) are used to keep the upper airway open to provide unobstructed ventilation. Early (first-generation) SADs rapidly replaced endotracheal intubation and face masks in > 40% of general anesthesia cases due to their versatility and ease of use. Second-generation devices have further improved efficacy and utility by incorporating design changes. Individual second-g...

T HE supraglottic airways have gained firm places in anesthetic practice since clinical introduction of the laryngeal mask airway (LMA) Classic (LMA North America, Inc., San Diego, CA) in 1988. Although they are generally being used safely, serious complications occasionally do occur during the use of the airways. To increase safety, we need to know the types, severity, and possible causative f...

BACKGROUND Alternatives to endotracheal intubation (ETI) are required when access to the cranial end of the patient is restricted. In this study, the success rate and time duration of standard intubation techniques were compared with two different supraglottic devices. Two different manikins were used for the study, and the training effect was studied when the same manikin was repeatedly used. ...

A 60-year-old Hispanic male with a history of smoking presented to the emergency department with complaint of dysphagia for the past two months. Additional symptoms included progressive shortness of breath and stridor. CT results from an outside institution showed 80% airway obstruction. Despite the findings, the patient’s vitals were normal, with respirations of 20 and an initial room air oxyg...

The aim of this study is to determine whether there is a role of podoplanin and glutathione S-transferases T1 (GST-T1) expression in laryngeal squamous cell carcinoma. The study was completed with 33 patients and gene expression analysis was performed by qRT–PCR. The podoplanin and GST-T1 expression patterns were analyzed to determine their correlation with clinicopathologic parameters of lar...
