Evaluation of Techniques for Tracheal Tube Exchange in Standard and Critical Care Patients

A randomized controlled study to evaluate different Techniques and Approachs for the Exchange of a tracheal tube or supraglottic airway device in a Simulator


Exchanging a tracheal tube (ETT) in the high-risk difficult airway patient carries the risk of hypoxemia and the potential of a lost airway. Maintaining continuous airway access during the exchange by incorporating an airway exchange catheter (AEC) or similar device may reliably lessen exchange risk, especially in the known or suspected difficult airway patient, by providing a conduit to facilitate ETT passage into the trachea. We evaluated some approven / etablished techniques in a Simulator based study design.

Use of Laryngeal Mask Airway in Pediatric Adenotonsillectomy

The aim of the current study is to compare the use of laryngeal mask airway (LMA) and endotracheal tube (ETT) in pediatric adenotonsillectomy. The primary objective is to assess the incid...

Is Endotracheal Tube Use Mandatory in Patients Undergoing Nasal Septum Surgery?

The efficacy of supraglottic airway device use in many surgeries has been shown. Due to concerns such as tracheal blood leakage and vocal cord contamination in nasal septum surgery, there ...

Endotracheal tube cuff failure due to a disconnected component of the pressure-limiting valve.

In the use of a cuffed endotracheal tube (ETT), the cuff is inflated and deflated. However, cutting or kinking of the cuff-inflating tube can prevent this function. In this letter, we describe a ca...

The distance between the glottis and cuff of a tracheal tube placed through three supraglottic airway devices in children: A randomised controlled trial.

After tracheal tube insertion via various types of supraglottic airway devices, the distance from the tube cuff to the vocal cords has not been evaluated in children.

Medical and Biotech [MESH] Definitions

Removal of an endotracheal tube from the patient.

Procedure in which an anesthetic such as a gas or mixture of gases is inhaled through a tube into the lungs.

A tube of ectodermal tissue in an embryo that will give rise to the CENTRAL NERVOUS SYSTEM, including the SPINAL CORD and the BRAIN. Lumen within the neural tube is called neural canal which gives rise to the central canal of the spinal cord and the ventricles of the brain. For malformation of the neural tube, see NEURAL TUBE DEFECTS.

A type of oropharyngeal airway that provides an alternative to endotracheal intubation and standard mask anesthesia in certain patients. It is introduced into the hypopharynx to form a seal around the larynx thus permitting spontaneous or positive pressure ventilation without penetration of the larynx or esophagus. It is used in place of a facemask in routine anesthesia. The advantages over standard mask anesthesia are better airway control, minimal anesthetic gas leakage, a secure airway during patient transport to the recovery area, and minimal postoperative problems.

Congenital malformations of the central nervous system and adjacent structures related to defective neural tube closure during the first trimester of pregnancy generally occurring between days 18-29 of gestation. Ectodermal and mesodermal malformations (mainly involving the skull and vertebrae) may occur as a result of defects of neural tube closure. (From Joynt, Clinical Neurology, 1992, Ch55, pp31-41)
