Cricothyrotomy

BACKGROUND: Medical simulation is essential for surgical training yet is often too expensive and inaccessible in low- and middle-income countries (LMICs). Furthermore, in otolaryngology-head and neck surgery (OHNS), while simulation training is often focused on senior residents and specialists, there is a critical need to target general practitioners who carry a significant load of OHNS care in countries with limited OHNS providers. This scoping review aims to describe affordable, effective OHNS simulation models for early-stage trainees and non-OHNS specialists in resource-limited settings and discuss gaps in the literature...

BACKGROUND: Airway management is a cornerstone in the prehospital care of critically ill or injured patients. Surgical cricothyrotomy offers a rapid and effective solution when oxygenation and ventilation fail using less-invasive techniques. However, the exact indications, incidence, and success of prehospital surgical cricothyrotomy are unknown, with variable rates reported in the literature. This study aimed to examine prehospital indications and success rates for surgical cricothyrotomy within a large, suburban, ground-based Emergency Medical Services (EMS) system...

OBJECTIVES: The study's primary goal was to assess the feasibility of the cricothyroidotomy technique (CTT) in cats and evaluate its success rate (i.e., secure airway access). Secondary outcomes were the assessment of the subjective difficulty of airway access based on body score condition and weight. Further secondary outcomes consisted of procedural time and scoring of associated complications. The current study hypothesized that the CTT procedure would provide secure airway access with a reasonable success rate...

Introduction  Cricothyrotomy, percutaneous dilation tracheostomy, and tracheostomy are all cost-effective and safe techniques used in the management of critically ill patients who need an artificial airway other than endotracheal tube ventilation. The present study focused on enlightening on elective and emergency procedures performed on conditions present with difficult airways and also attempts to shed light on the aspects of securing an airway in anticipated and unanticipated difficult intubation...

Certified registered nurse anesthetists (CRNAs) who are responsible for airway management, may lack adequate continuing education for emergency front of neck access (EFONA), an advanced skill necessary in situations when a patient cannot be intubated and cannot be oxygenated (CICO). The purpose of this study was to improve CRNA knowledge and confidence when performing a scalpel-bougie cricothyrotomy for EFONA in a CICO event through the implementation of a spaced learning intervention. Thirteen CRNAs at a 160-bed community hospital participated in a 3-week educational intervention...

BACKGROUND: Cricothyrotomy is a lifesaving surgical technique in critical airway events. However, a large proportion of anesthesiologists have little experience with cricothyrotomy due to its low incidence. This study aimed to develop a multisensory, readily available training curriculum for learning cricothyrotomy and evaluate its training effectiveness. METHODS: Seventy board-certificated anesthesiologists were recruited into the study. Participants first viewed an instructional video and observed an expert performing the bougie-assisted cricothyrotomy on a self-made simulator...

OBJECTIVES: Advanced Trauma Life Support (ATLS) focuses on care of injured patients in the first hour of resuscitation. Expanded demand for courses has led to a concurrent need for new instructors. Nurse practitioners and physician assistants (NPs/PAs) work on trauma services and duties include patient, staff, and outreach education. The goal of this project was to assess NP/PA self-reported knowledge and skills pertinent to ATLS and identify potential barriers to becoming instructors...

BACKGROUND: Cricothyrotomy is an invasive and rare emergency intervention to secure the airway in a "cannot intubate, cannot ventilate" situation. This leads to lack of routine. Cricothyrotomy is performed only hesitantly. Therefore, we aim to improve teaching by including a virtual reality (VR) cricothyrotomy as a learning tool. METHODS: We programmed the VR cricothyrotomy in the C# programming language on the open-source Unity platform. We could include 149 students that we randomly assigned to either a study group (VR cricothyrotomy) or control group (educational video)...

INTRODUCTION: Patients with acute upper gastrointestinal bleeding may have challenging airways. This simulation teaches anesthesiology residents the skill of cricothyrotomy as a surgical last resort while managing acute bleeding in the airway. METHODS: The simulation involved a 55-year-old patient with history of alcohol abuse admitted to the ICU with hematemesis and acute blood loss for esophagogastroduodenoscopy in the ICU setting. The mannequin had tubing in the posterior oropharynx connected to a pressurized bag of simulated blood hidden from view...

IMPORTANCE: There is a notable lack of low-cost OHNS simulation models that are relevant for early medical trainees and students. By conducting this study, we will understand the current landscape of low-cost otolaryngology-head and neck surgery simulation for early medical trainees and students. OBJECTIVES: Medical simulation is essential for surgical training yet is often too expensive and inaccessible in low- and middle-income countries (LMICs). Furthermore, in otolaryngology-head and neck surgery (OHNS), while simulation training is often focused on senior residents and specialists, there is a critical need to target general practitioners who carry a significant load of OHNS care in countries with limited OHNS providers...

Mental practice is an effective method for skill acquisition in medicine. We describe the integration of interview-derived sensory cues with a list of procedural steps into a cohesive script to facilitate mental practice for a High Acuity, Low-Occurrence procedure, the bougie-assisted cricothyrotomy. Data collection occurred through interviews with emergency physicians. Interview transcripts were analyzed on a coding framework based on a previously published list of procedural steps. These cues were integrated with procedural steps to create a narrative script...

OBJECTIVES: Cricothyrotomy is a high-stakes emergency procedure. Because the procedure is rare, simulation is often used to train residents. The Accreditation Council for Graduate Medical Education (ACGME) requires performance of three cricothyrotomies during residency, but the optimal number of training repetitions is unknown. Additional repetitions beyond three could increase proficiency, though it is unknown whether there is a threshold beyond which there is no benefit to additional repetition...

This study evaluated the effect of an airway localization device (ALD) on surgical cricothyrotomy (SC) success rates and prehospital provider confidence. SC is indicated in 0.62% to 1.8% of all patients with military trauma, especially those presenting with traumatic airway obstruction. The effect of ALD was evaluated in an airway mannequin model during SC with the Committee on Tactical Combat Casualty Care (CoTCCC)-recommended Control-Cric Cricothyrotomy System. Outcomes included procedural time, Likert measures of operator confidence, and qualitative data/feedback for suggested future improvements in device design and training...

INTRODUCTION: U.S. Military healthcare providers increasingly perform prolonged casualty care because of operations in settings with prolonged evacuation times. Varied training and experience mean that this care may fall to providers unfamiliar with providing critical care. Telemedicine tools with audiovisual capabilities, artificial intelligence (AI), and augmented reality (AR) can enhance inexperienced personnel's competence and confidence when providing prolonged casualty care. Furthermore, implementing offline functionality provides assistance options in communications-limited settings...

OBJECTIVE: In typical surgical tracheostomy, the thyroid isthmus is divided or retracted superiorly and preserved. However, at our institution, the thyroid isthmus is retracted inferiorly and preserved. Thereafter, a tracheal incision is made above the thyroid isthmus. This method, hereinafter defined as high tracheostomy, has the advantage of facilitating immediate access to the trachea in a superficial position; moreover, it can be quickly replaced with cricothyrotomy in emergency situations...

OBJECTIVES: The primary aim of this study was to determine the average cricothyroid membrane (CTM) height in healthy volunteers, and the secondary aim was to determine the hypothetical success rate for emergency cricothyrotomy with a tracheal tube with an 8.0 mm outer diameter. METHODS: This study included healthy volunteers aged 18 years and older. The participants' clinical characteristics were recorded, and their CTM height was measured using ultrasound, with their necks placed sequentially in the neutral and extension positions...

BACKGROUND: The objective of this study is to describe the education, training, and use of prehospital surgical airways in a rural Emergency Medical Service (EMS) system. MATERIALS AND METHODS: We conducted an internet-based survey instrument of all advanced life support (ALS) EMS agencies in a seven-county rural EMS system in Pennsylvania. ALS agencies were queried regarding basic demographic information as well as the number of surgical airways performed in the previous 10 years as well as the education and training of EMS providers in surgical airways...

BACKGROUND: Cricothyrotomy is a procedure performed to establish an airway in critical airway events. It is performed only rarely and anesthesiologists are often unprepared when called upon to perform it. This study aimed to simulate cricothyrotomy using pig larynx and trachea models to help anesthesiologists master cricothyrotomy and improve the ability to establish cricothyrotomy quickly. METHODS: The porcine larynx and trachea were dissected and covered with pigskin to simulate the structure of the anterior neck of a human patient...

PURPOSE: Emergency surgical airway securing techniques include cricothyrotomy, puncture, and incision. While the instruments used for these methods vary in size, no index of laryngeal morphology exists to guide instrument selection. Therefore, we measured the morphology of the cricothyroid ligament in Japanese individuals and assessed its correlations with height. METHODS: This retrospective study used 61 anatomical practice specimens. The cricothyroid ligament of the laryngeal area was dissected, and a frontal image was recorded...
