Comparison of Two Types of Videolaryngoscope and Direct Laryngoscope in Expected Non-difficult Airway Patients

2019-12-08 01:41:39 | BioPortfolio


Macintosh direct laryngoscope has been mostly widely used for anesthesiologists in operation rooms or emergency situations all over the world. With rapidly development of technical divices, nowadays videolaryngoscope has become more and more popular in hospitals, for it could improve first intubation success rate and it is easier for beginners to learn. And there are many different types of videolaryngoscope for different purpose, like with or without a channel, different curvature, and so go. In this study, our aim is to study whether the videolaryngoscope which can be adjustable or not costs less intubation time and causes fewer injury in expected non-difficult airway patients by experienced anesthesiologists, compared with the classic Macintosh direct laryngoscope.

Medical and Biotech [MESH] Definitions

Abnormally slow pace of regaining CONSCIOUSNESS after general anesthesia (ANESTHESIA, GENERAL) usually given during surgical procedures. This condition is characterized by persistent somnolence.

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.

Procedure in which patients are induced into an unconscious state through use of various medications so that they do not feel pain during surgery.

A procedure involving placement of a tube into the trachea through the mouth or nose in order to provide a patient with oxygen and anesthesia.

A barbiturate that is administered intravenously for the induction of general anesthesia or for the production of complete anesthesia of short duration. It is also used for hypnosis and for the control of convulsive states. It has been used in neurosurgical patients to reduce increased intracranial pressure. It does not produce any excitation but has poor analgesic and muscle relaxant properties. Small doses have been shown to be anti-analgesic and lower the pain threshold.
