Effect of air, anesthetic gas mixture, saline, or 2% lignocaine used for tracheal tube cuff inflation on coughing and laryngotracheal morbidity after tracheal extubation.

Background And Aims: Coughing and sore throat postoperatively are common clinical problems during general anesthesia which can be avoided by various methods including topicalization of airway with local anesthetics, endotracheal tube cuff (ETT) inflation with local anesthetics, use of intravenous drugs such as dexamethasone, maintaining ETT cuff pressure, intubation by an experienced anethesiologist, etc. The aims of the study were to compare postextubation coughing response, mean number of cuff deflations required intraoperatively, and postoperative airway morbidity in terms of sore throat (2 h and 18-24 h), hoarseness of voice, and dysphagia following inflation of ETT cuff with air, anesthetic gas mixture, saline, and 2% lignocaine during general anesthesia.

Material And Methods: One hundred and four patients were randomized into 1 of 4 groups depending on whether air, anesthetic gas mixture, saline, or 2% lignocaine was used to inflate the cuff of ETT using computer-generated randomization table.

Comparison of laryngeal mask airway CTrach™ and Airtraq videolaryngoscopes as conduits for endotracheal intubation in patients with simulated limitation of cervical spine movements by manual in-line stabilization.

Background And Aims: Laryngeal mask airway (LMA) CTrach™ and Airtraq videolaryngoscopes are useful for endotracheal intubation in patients with limited cervical spine movements and other predicted difficult airways. We aimed to compare LMA CTrach™ and Airtraq videolaryngoscopes as conduits for endotracheal intubation in patients with simulated limitation of cervical spine movements by manual in-line stabilization (MILS).

Material And Methods: This was a prospective, randomized study including 50 patients undergoing elective surgeries under general anesthesia.
