Lower Adherence

The role of advanced airway management (AAM) in cardiopulmonary resuscitation (CPR) is currently debated as observational studies reported better outcomes after bag-mask ventilation (BMV), and the only prospective randomized trial was inconclusive. Adherence to CPR guidelines ventilation recommendations is unknown and difficult to assess in clinical trials. This study compared AAM and BMV with regard to adherence to ventilation recommendations and chest compression fractions in simulated cardiac arrests. A total of 154 teams of 3–4 physicians were randomized to perform CPR with resuscitation equipment restricting airway management to BMV only or equipment allowing for all forms of AAM. BMV teams ventilated 6 ± 6/min and AAM teams 19 ± 8/min (range 3–42/min; p < 0.0001 vs. BMV). 68/78 BMV teams and 23/71 AAM teams adhered to the ventilation recommendations (p < 0.0001). BMV teams had lower compression fractions than AAM teams (78 ± 7% vs. 86 ± 6%, p < 0.0001) resulting entirely from higher no-flow times for ventilation (9 ± 4% vs. 3 ± 3 %; p < 0.0001). Compared to BMV, AAM leads to significant hyperventilation and lower adherence to ventilation recommendations but favourable compression fractions. The cumulative effect of deviations from ventilation recommendations has the potential to blur findings in clinical trials.

Randomized Crossover Study

Background Because airway management plays a key role in emergency medical care, methods other than laryngoscopic tracheal intubation (LG-TI) are being sought for inadequately experienced personnel. This study compares success rates for ventilation and intubation via the intubating laryngeal mask (ILMA-V/ILMA-TI) with those via bag-mask ventilation and laryngoscopic intubation (BM-V/LG-TI). Methods In a prospective, randomized, crossover study, 30 final-year medical students, all with no experience in airway management, were requested to manage anesthetized patients who seemed normal on routine airway examination. Each participant was asked to intubate a total of six patients, three with each technique, in a randomly assigned order. A task not completed after two 60-s attempts was recorded as a failure, and the technique was switched. Results The success rate with ILMA-V was significantly higher (97.8% vs. 85.6%; P &lt; 0.05), and ventilation was established more rapidly with ILMA-V (35.6 +/- 8.0 vs. 44.3 +/- 10.8 s; P &lt; 0.01). Intubation was successful more often with ILMA-TI (92.2% vs. 40.0%; P &lt; 0.01). The time needed to achieve tracheal intubation was significantly shorter with ILMA-TI (45.7 +/- 14.8 vs. 89.1 +/- 23.3 s; P &lt; 0.01). After failed LG-TI, ILMA-V was successful in all patients, and ILMA-TI was successful in 28 of 33 patients. Conversely, after failed ILMA-TI, BM-V was possible in all patients, and LG-TI was possible in 1 of 5 patients. Conclusion Medical students were more successful with ILMA-V/ILMA-TI than with BM-V/LG-TI. ILMA-TI can be successfully used when LG-TI has failed, but not vice versa. These results suggest that training programs should extend the ILMA to conventional airway management techniques for paramedical and medical personnel with little experience in airway management.

Respiratory Assistance

The basic skills required for competence in pediatric airway management include mask ventilation, supraglottic airway placement, direct laryngoscopy, and intubation. Although techniques used for children are similar to those used for adults, there are some nuances that pertain only to the pediatric patient. This chapter describes and illustrates these basic airway management procedures for pediatric patients. Bag mask ventilation is used extensively in the operating room, emergency department, and intensive care unit. Effective bag mask ventilation can save a child’s life in emergent situations.1 Respiratory assistance is provided to the patient through a mask on the patient’s face, held in a specialized way to maximize airway patency (described later), that is attached to a device capable of delivering positive pressure manually or automatically. Oxygenation is achieved by compressing air/oxygen through the delivery device into the lungs, and ventilation is ensured by maintaining airway patency as the patient exhales with chest wall recoil. Intubation is indicated in any patient who is unable to maintain adequate spontaneous respiration or who is at risk for aspiration. Examples are patients in respiratory arrest, those in cardiac arrest, or sometimes those experiencing neurologic issues such as seizures. Patients undergoing surgical procedures will often require intubation because of the apnea and risk for aspiration caused by the anesthetics and the surgical procedure itself.

Bag Mask Ventilation

Objective: Bag mask ventilation (BMV) is fundamental to airway management. Simulation is effective in airway management training, but its effectiveness for difficult BMV training is less clear. We evaluated the difference between type of training (simulation vs on patients) and the pass rate on a post-test on patients. Design: A single center pilot study was performed with 32 medical students randomized to participate in difficult BMV training on simulators or patients. Pre- and post-training tests on the simulator and on patients were recorded. Surveys of trainee confidence level were collected. The primary goal was to estimate the difference between type of training (simulation vs on patients) and the pass rate on the post-test on patients with an improvement of 10% or more in passing rate considered as a meaningful improvement. Secondary outcomes included whether or not participants passed the simulator post-test, post-test on patient confidence, and pre- and post-test confidence. Measurements and main results: Participants trained on the simulator had 13% higher passing rate on the post-test on patients compared to participants trained on patients (88% vs 75%). In addition, subjects that passed the simulator post-test had 11 times the odds of passing a post-test on patients relative to subjects that did not pass the simulator post-test ( P = 0.023, odds ratio = 11.0, 95% confidence interval [CI] = 1.48-81.6). Post-training confidence levels were higher among those who passed the simulator pre-test and post-test and received simulator training. Conclusions: Simulation training for difficult BMV led to a higher passing rate on a post-test on patients compared to those trained on patients. This finding will need to be confirmed in larger randomized controlled trials. Successfully completing difficult BMV training on a simulator with a passing grade correlated with passing a test on difficult BMV on patients.

Adequate Oxygenation

In difficult airway situations, the next step of the airway management method is selected according to the prior presence of difficulties in mask ventilation and endotracheal intubation. It is important for the practitioner to be calm, quick in judgment, and take action in cases of difficult intubation. Recently, high-flow nasal oxygenation has been rapidly introduced into the anesthesiology field. This technique could extend the safe apnea time to desaturation. Especially, it maintains adequate oxygenation even in apnea and allows time for intubation or alternative airway management. We report two cases in which high-flow nasal oxygenation was implemented in the middle of the induction process after quick judgment by clinicians. High-flow nasal oxygenation was successfully used to assist in prolonging the safe apnea time during delicate airway securing attempts.
