Difficult Mask Ventilation in Penetrating Facial Trauma Due to Animal Attack: A Unique Challenge in the Emergency Department

Penetrating facial trauma can be a life-threatening condition, especially due to its impact on the airway. In a facial trauma, there is a distortion in the basic anatomy of the affected, making it a particularly difficult situation for managing the airway. Challenging intubation scenarios have been widely explored in the literature; however, difficult to ventilate situations have been undermined. We describe a case of a 35-year-old female who presented with a history of animal attack on the face. The extent of penetrating facial trauma warranted the need to secure the airway. Preserving spontaneous breathing and using an oral endotracheal tube for oxygenation saved the airway manager from cannot intubate and cannot oxygenate situation in a facial trauma patient.

Difficult to mask ventilate while arranging for a definitive airway can be more pressing and challenging for the emergency physician. It also jeopardizes the patient's life, whose survival may only depend on acquiring the patency of the airway. Facial trauma patients may be conscious and spontaneously breathing, leading to the missed or delayed intervention in the airway; hence, prompt assessment and management of the airway in all facial trauma are of utmost importance.

Chest trauma in children-what an anesthesiologist should know

Injury is the leading cause of death in children, with chest trauma accounting for 25% of this mortality. In addition, these patients often present with multiple system injuries, which require simultaneous management. These concurrent injuries can lead to challenges when prioritizing tasks in the resuscitation room and during anesthetic management. In addition, changes from spontaneous ventilation to positive pressure ventilation can impact lung physiology. Therefore, a clear communication plan with careful monitoring and vigilance is needed for intubation and ventilation in these children. These injuries also require specific strategies to prevent barotrauma which could lead to complications such as respiratory failure, pneumonia, sepsis, and acute respiratory distress syndrome. This educational review aims to guide clinicians managing pediatric chest trauma through some of the critical decision-making regarding intubation, ventilation, and subsequent management of injuries.

Selective intubation with endotracheal tube introducer in difficult airway: A randomized, prospective, cross-over study

BACKGROUND:

Selective lung intubation is a life-saving procedure in emergency departments. While various equipment can be used in selective lung intubation, most of this equipment is not readily available; therefore, single-lumen endotracheal intubations are performed for rapid interventions.

MATERIALS AND METHODS:

This study was designed as a randomized, prospective, cross-over study using the 90° rotation technique for selective intubation on a manikin model with and without endotracheal tube introducer (ETI) in difficult airway settings. Forty-six emergency physicians were included in the study. The primary outcome was evaluating time to selective intubations, and secondary outcomes were first and second attempt success rates and the self-perceived difficulty level of each method according to the participants.

RESULTS:

The mean time to the first successful endotracheal intubation was significantly longer for both right selective and left selective intubations with ETI utilization than without ([39.71 ± 9.83 vs. 21.86 ± 5.94 s], [P < 0.001]), ([42.2 ± 10.81 vs. 26.23 ± 7.97 s], [P < 0.001], respectively). The first-pass success rate did not differ for right selective intubation with or without an ETI (45/46 [97.8%] and 45/46 [97.8%], respectively). However, the first-pass success rate for left selective intubation was significantly higher with ETI as compared to without an ETI (30/46 [65.2%] and 13/46 [28.3%], respectively) (P < 0.001).

CONCLUSIONS:

While the success rates of right selective intubation were the same, the left selective intubation success rates with ETI are higher than the styletted endotracheal tube, which can be strong evidence for this method's applicability in practice. Expanding the use of ETI and increasing the experience of the practitioners can contribute to further success.

Suction Assisted Laryngoscopy and Airway Decontamination (SALAD): A technique for improved emergency airway management

Emergency airway management is often complicated by the presence of blood, emesis or other contaminants in the airway. Traditional airway management education has lacked task-specific training focused on mitigating massive airway contamination. The Suction Assisted Laryngoscopy and Airway Decontamination (SALAD) technique was developed in order to address the problem of massive airway contamination both in simulation training and in vivo. We review the evidence describing the dangers associated with airway contamination, and describe the SALAD technique in detail.

The suction-assisted laryngoscopy assisted decontamination technique toward successful intubation during massive vomiting simulation: A pilot before-after study

This study demonstrated a training program of the suction-assisted laryngoscopy assisted decontamination (S.A.L.A.D.) technique for emergency medical technician paramedic (EMT-P). The effectiveness of the training program on the improvements of skills and confidence in managing soiled airway was evaluated.In this pilot before-after study, 41 EMT-P participated in a training program which consisted of 1 training course and 3 evaluation scenarios. The training course included lectures, demonstration, and practice and focused on how to perform endotracheal intubation in soiled airway with the S.A.L.A.D technique. The first scenario was performed on standard airway mannequin head with clean airway (control scenario). The second scenario (pre-training scenario) and the third scenario (post-training scenario) were performed in airway with simulated massive vomiting. The post-training scenario was applied immediately after the training course. All trainees were requested to perform endotracheal intubation for 3 times in each scenario. The "pass" of a scenario was defined as more than twice successful intubation in a scenario. The intubation time, count of successful intubation, pass rate, and the confidence in endotracheal intubation were evaluated.The intubation time in the post-training scenario was significantly shorter than that in the pre-training scenario (P = .031). The pass rate of the control, pre-training, and post-training scenario was 100%, 82.9%, and 92.7%, respectively. The proportion of trainees reporting confident or very confident in endotracheal intubation in soiled airway increased from 22.0% to 97.6% after the training program. Kaplan-Meier analysis revealed that the adjusted hazard ratio of successful intubation for post-training versus pre-training scenario was 2.13 (95% confidence interval of 1.57-2.91).The S.A.L.A.D. technique training could efficiently help EMT-P performing endotracheal intubation during massive vomiting simulation.
