Optimal End-Tidal (ET) Sevoflurane and Desflurane Concentration for Extubation of Supreme Laryngeal Mask Airway (LMA) in Adults

2014-08-27 03:15:19 | BioPortfolio

Summary

The purpose of this study is to determine the optimal volatile anaesthetic (sevoflurane and desflurane) to remove a Supreme LMA in adults in which there is minimal airway response.

Null hypothesis: there is no significant difference between the optimal end tidal concentration of sevoflurane and desflurane for Supreme LMA removal.

Description

The manufactures' instructions for removal of the LMA recommend waiting until protective reflexes have returned. However, the appropriate timing for removal remains controversial. A more frequent incidence of airway hyperreactivity and complications has been reported by some studies when the LMA was removed in the awake state versus the anesthetized state. Techniques that reduce the time from LMA removal to the return of protective airway reflexes would minimize the risk of aspiration, contamination, or airway obstruction.

With increasingly common use of Supreme LMA in anaesthetic practice, a safe and suitable depth for removal of the Supreme LMA requires research.

Thus the determination of the optimal end-tidal concentration of commonly used volatile agents ie. Sevoflurane and Desflurane for Supreme LMA removal requires research, both for patient safety and minimising anaesthetic costs in dealing with airway complications.

Medical and Biotech [MESH] Definitions

A form of bronchial disorder with three distinct components: airway hyper-responsiveness (RESPIRATORY HYPERSENSITIVITY), airway INFLAMMATION, and intermittent AIRWAY OBSTRUCTION. It is characterized by spasmodic contraction of airway smooth muscle, WHEEZING, and dyspnea (DYSPNEA, PAROXYSMAL).

Complications that affect patients during surgery. They may or may not be associated with the disease for which the surgery is done, or within the same surgical procedure.

The structural changes in the number, mass, size and/or composition of the airway tissues.

Evaluation, planning, and use of a range of procedures and airway devices for the maintenance or restoration of a patient's ventilation.

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.
