Is there a benefit for anesthesiologists of adding difficult airway scenarios for learning fiberoptic intubation skills using virtual reality training? A randomized controlled study.

Fiberoptic intubation for a difficult airway requires significant experience. Traditionally only normal airways were available for high fidelity bronchoscopy simulators. It is not clear if training on difficult airways offers an advantage over training on normal airways. This study investigates the added value of difficult airway scenarios during virtual reality fiberoptic intubation training. A prospective multicentric randomized study was conducted 2019 to 2020, among 86 inexperienced anesthesia residents, fellows and staff. Two groups were compared: Group N (control, n = 43) first trained on a normal airway and Group D (n = 43) first trained on a normal, followed by three difficult airways. All were then tested by comparing their ORSIM® scores on 5 scenarios (1 normal and 4 difficult airways). The final evaluation ORSIM® score for the normal airway testing scenario was significantly higher for group N than group D: median score 76% (IQR 56.5-90) versus 58% (IQR 51.5-69, p = 0.0039), but there was no difference in ORSIM® scores for the difficult intubation testing scenarios. A single exposure to each of 3 different difficult airway scenarios did not lead to better fiberoptic intubation skills on previously unseen difficult airways, when compared to multiple exposures to a normal airway scenario. This finding may be due to the learning curve of approximately 5-10 exposures to a specific airway scenario required to reach proficiency.

The effects of personal protective equipment on airway management: An in-situ simulation.

The novel coronavirus disease (COVID-19) was declared a pandemic by the World Health Organisation on 11th March and has led to over 41,000 deaths in the UK. Public Health England guidance for aerosol generating procedures (AGP) requires the donning of personal protective equipment (PPE). We evaluated airway management skills using an in-situ emergency simulation. The scenarios were video recorded and scored by two independent assessors using a skill specific checklist. A total of 34 airway management procedures were evaluated. The checklist involved 13 steps with a maximum score of 26. The median (IQR [range]) checklist score was 25 (24-25 [20-26]). Four teams failed to intubate the trachea and proceeded to manage the airway using a supraglottic airway device. The mean (SD) intubation time was 47.9 (16.5) seconds and two anaesthetists (7%) required a second attempt. Our results show that airway management can be carried out successfully whilst donned in PPE. However, additional training in using newly introduced devices such as a McGrath® video laryngoscope is of paramount importance.

Role of Ultrasound in Emergency Front of Neck Access: A Case Report and Review of Literature.

Emergency front of neck access (eFONA) is a lifesaving procedure in a cannot intubate cannot oxygenate (CICO) situation. We report a case of a patient who presented to the emergency department (ED) in extremis with a difficult airway. A history of multiple neck surgeries and permanent tracheostomy from birth until the age of 17 years complicated his airway management. Altered neck anatomy led to failed intubation and oxygenation. EFONA was established with the use of rapid ultrasound imaging and using the scalpel-bougie-tube technique. We present a review of literature relating to the use of ultrasound during emergency airway management.

Emergency front of neck airway: What do trainers in the UK teach? A national survey.

BACKGROUND AND AIMS: Front of neck airway (FONA) is the final step to deliver oxygen in the difficult airway management algorithms. The Difficult Airway Society 2015 guidelines have recommended a standardized scalpel cricothyroidotomy technique for an emergency FONA. There is a wide variability in the FONA techniques with disparate approaches and training. We conducted a national postal survey to evaluate current teaching, availability of equipment, experienced surgical help and prevalent attitudes in the face of a can't intubate, can't oxygenate situation. MATERIAL AND METHODS: The postal survey was addressed to airway leads across National Health Service hospitals in the United Kingdom (UK). In the anesthetic departments with no designated airway leads, the survey was addressed to the respective college tutors. A total of 259 survey questionnaires were posted. RESULTS: We received 209 survey replies with an overall response rate of 81%. Although 75% of respondents preferred scalpel cricothyroidotomy, only 28% of the anesthetic departments considered in-house FONA training as mandatory for all grades of anesthetists. Scalpel-bougie-tube kits were available in 95% of the anesthetic departments, either solely or in combination with other FONA devices. CONCLUSION: The survey has demonstrated that a majority of the airway trainers in the UK would prefer scalpel cricothyroidotomy as emergency FONA. There is a significant variation and deficiency in the current levels of FONA training. Hence, it is important that emergency FONA training is standardized and imparted at a multidisciplinary level.

Advanced airway training in the UK: A national survey of senior anesthetic trainees.

BACKGROUND AND AIMS: High-quality training in advanced airway skills is imperative to ensure safe anesthetic care and develop future airway specialists. Modern airway management skills are continually evolving in response to advancing technology and developing research. Therefore, it is of concern that training provisions and trainee competencies remain current and effective. MATERIAL AND METHODS: A survey questionnaire based on the airway competencies described in the Royal College of Anaesthetists' curriculum and Difficult Airway Society guidelines was posted to all United Kingdom (UK) National Health Service hospitals to be completed by the most senior anesthetic trainee (ST 5-7, resident). RESULTS: A total of 149 responses were analyzed from 237 hospitals with eligible anesthetic trainees (response rate 63%), including 53 (36%) and 39 (26%) respondents who had completed higher and advanced level airway training respectively. Although clinical experience with videolaryngoscopy was satisfactory, poor confidence and familiarity was identified with awake fiberoptic intubation, high frequency jet ventilation, at risk extubation techniques, and airway ultrasound assessment. Only 26 (17%) respondents had access to an airway skills room or had regular airway emergency training with multidisciplinary theater team participation. Reported barriers to training included lack of training lists, dedicated teaching time, experienced trainers, and availability of equipment. CONCLUSIONS: This national survey identified numerous deficiencies in airway competencies and training amongst senior anesthetic trainees (residents) in the UK. Restructuring of the airway training program and improvements in access to training facilities are essential to ensure effective airway training and the capability to produce future airway specialists.

Front of neck access: A survey among anesthetists and surgeons.

BACKGROUND AND AIMS: Emergency front of neck access (FONA) is the final step in a Can't Intubate-Can't Oxygenate (CICO) scenario. In view of maintaining simplicity and promoting standardized training, the 2015 Difficult Airway Society guidelines recommend surgical cricothyroidotomy using scalpel, bougie, and tube (SBT) as the preferred technique. MATERIAL AND METHODS: We undertook a survey over a 2-week period to evaluate the knowledge and training, preferred rescue technique, and confidence in performing the SBT technique. Data were collected from both anesthetists and surgeons. RESULTS: One hundred and eighty-nine responses were collected across four hospitals in the United Kingdom. The majority of participants were anesthetists (55%). One hundred and eleven (59%) respondents were aware of the national guidelines (96.2% among anesthetists and 12.9% among surgeons). Only 71 (37.6%) respondents indicated that they had formal FONA training within the last one year. Seventy-five anesthetists (72.8%) knew that SBT equipment was readily available in their department, while most surgeons (81.2%) did not know what equipment available. One hundred and five (55.5%) respondents were confident in performing surgical cricothyroidotomy in a situation where the membrane was palpable and only in 33 (17.5%) where the cricothyroid membrane was not palpable. CONCLUSION: This survey has demonstrated that despite evidence of good training for anesthetists in FONA, there are still shortfalls in the training and knowledge of our surgical colleagues. In an emergency, surgeons may be required to assist or secure an airway in a CICO situation. Regular multidisciplinary training of all clinicians working with anesthetized patients should be encouraged and supported.

Tracheal Extubation of Patients With Cervical Spine Injury: A Case Report and Review of Literature.

In patients with cervical spine injuries, emergence from anesthesia and tracheal extubation can prove as challenging to the anesthesiologist as the tracheal intubation. We report a case of a patient with a potentially unstable cervical spine injury who presented for a nonspinal surgery and experienced agitation on emergence from anesthesia. The use of an intravenous sedative was necessary to ensure cervical spine immobilization but was complicated by severe respiratory depression and the need for reintubation and admission to intensive care. The case report is followed by a review of literature relating to safe extubation of patients with cervical spine injuries. Possible complications during emergence and various methods to prevent these complications are discussed.

Awake tracheal intubation using Pentax airway scope in 30 patients: A Case series.

BACKGROUND AND AIMS: Pentax airway scope (AWS) has been successfully used for managing difficult intubations. In this case series, we aimed to evaluate the success rate and time taken to complete intubation, when AWS was used for awake tracheal intubation. METHODS: We prospectively evaluated the use of AWS for awake tracheal intubation in 30 patients. Indication for awake intubation, intubation time, total time to complete tracheal intubation, laryngoscopic view (Cormack and Lehane grade), total dose of local anaesthetic used, anaesthetists rating and patient's tolerance of the procedure were recorded. RESULTS: The procedure was successful in 25 out of the 30 patients (83%). The mean (standard deviation) intubation time and total time to complete the tracheal intubation was 5.4 (2.4) and 13.9 (3.7) min, respectively in successful cases. The laryngeal view was grade 1 in 24 and grade 2 in one of 25 successful intubations. In three out of the five patients where the AWS failed, awake tracheal intubation was successfully completed with the assistance of flexible fibre optic scope (FOS). CONCLUSION: Awake tracheal intubation using AWS was successful in 83% of patients. Success rate can be further improved using a combination of AWS and FOS. Anaesthesiologists who do not routinely use FOS may find AWS easier to use for awake tracheal intubation using an oral route.
