Different Techniques for Emergency Cricothyroidotomy

2014-07-23 21:09:29 | BioPortfolio

Summary

This educational study will examine two different techniques for training emergency residents and staff on achieving a surgical airway (called a cricothyroidotomy).

Description

Introduction: In patients that cannot be intubated or ventilated by conventional means an emergency cricothyroidotomy is a potentially life saving intervention that is the common final pathway of difficult airway algorithms. Significant debate surrounds the ideal method of performing an emergency cricothyroidotomy. The literature remains divided between the open (surgical) and closed (wire assisted, or Seldinger) techniques. We feel that these two methods are not mutually exclusive and are proposing a novel "incision first" modification to the traditional Seldinger closed technique. Making a small (1 cm) incision prior needle insertion could facilitate localization of landmarks and may improve speed or success rate of the closed Seldinger procedure.

Methods: Using concealed allocation, this randomized controlled cross-over trial will be performed in a laboratory setting. Outcome assessment will be blinded. Both staff and resident emergency physicians will be included in this trial. We will use a well-validated swine trachea model for this study.

Results: Results will be collected using standardized Case Report Forms (CRF) and independently entered into a pre-constructed Microsoft ACCESS database. The primary outcome will be time to procedure completion. Secondary outcomes will be proportion of successful cricothyroidotomy, complications and ease of procedure and ability to increase clinical confidence using this model. Paired t-tests and Fisher's exact test will be used to compare the outcomes and due to multiple statistical tests, a correction will be used to adjust for multiple tests (p < 0.025) to indicate significance.

Conclusions: This study will assess and evaluate both the incision first model and closed Seldinger cricothyroidotomy techniques. We will discuss the merits of each technique and the effectiveness of the model.

Medical and Biotech [MESH] Definitions

Techniques for administering artificial respiration without the need for INTRATRACHEAL INTUBATION.

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 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.

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).

A technique of respiratory therapy, in either spontaneously breathing or mechanically ventilated patients, in which airway pressure is maintained above atmospheric pressure throughout the respiratory cycle by pressurization of the ventilatory circuit.
