The efficacy and usability of suction-based airway clearance devices for foreign body airway obstruction: a manikin randomised crossover trial

Background

Newly-developed suction-based airway clearance devices potentially provide a novel way to improve outcome in patients with foreign body airway obstruction. We conducted a randomised controlled crossover manikin trial to compare the efficacy and usability of two of these devices with abdominal thrusts.

Methods

We randomised participants from a UK medical school to one of six groups which determined the order in which participants attempted the three techniques (abdominal thrusts; LifeVac, Nesconset, New York, USA; Dechoker, Concord North Carolina, USA). Randomisation was performed using an online randomisation system. Following brief training, participants sought to remove a foreign body airway obstruction from a manikin using the allocated technique. The primary outcome was successful removal of the foreign body. Usability was assessed in a questionnaire following the three simulations.

Results

We randomised and analysed data from 90 participants (58% male; 86% aged 18−29 years). Compared with abdominal thrusts, successful foreign body airway obstruction removal was achieved more frequently in manikins in the LifeVac group (odds ratio 47.32, 95% CI 5.75–389.40) but not in the Dechoker group (odds ratio 1.22, 95% CI 0.60–2.47). The usability of LifeVac and abdominal thrusts were generally evaluated more positively than the Dechoker.

Conclusion

In this manikin study, we found that, compared with abdominal thrusts, the success rate for foreign body airway obstruction removal was higher in the LifeVac group but not in the Dechoker group.

Removal of foreign body airway obstruction: A systematic review of interventions

OBJECTIVE

To summarise in a systematic review the effectiveness of interventions to treat foreign body airway obstructions (FBAO).

METHODS

We searched MEDLINE, EMBASE, and the Cochrane library from inception on 30th September 2019 for studies that described the effectiveness of interventions to treat FBAO in adults and children. We included randomised controlled trials, observational studies and case series (≥5 cases) that described evidence of benefit. For evidence of harm/complications, we included case reports. Two reviewers independently assessed study eligibility, extracted study data, and assessed risk of bias. Data are summarised in a narrative synthesis. The GRADE system is used to assess evidence certainty.

RESULTS

We included 69 publications, comprising three cross-sectional studies (557 patients); eight case series (755 patients), and 59 were case reports (64 patients). One paper was included as a case series and cross-sectional study. For all interventions and associated outcomes, evidence certainty was very low. Early removal of FBAO by bystanders was associated with improved neurological survival (odds ratio 6.0, 95% confidence interval 1.5 to 23.4). Identified evidence showed that key interventions (back blows, abdominal thrusts, chest thrusts/compressions, Magill forceps, manual removal of obstructions from the mouth, suction-based airway clearance devices) are effective in relieving FBAO. We identified reports of harm in relation to back blows, abdominal thrusts, chest thrusts/compressions, and blind finger sweeps.

CONCLUSIONS

Key interventions successfully relieve FBAO, but may be associated with important harms. Guidelines for FBAO management should balance the benefits and harms of interventions.

Risk Management and Recommendations for the Prevention of Fatal Foreign Body Aspiration: Four Cases Aged 1.5 to 3 Years and Mini-Review of the Literature

(1) Background: Foreign body aspiration (FBA) is a significant public health concern among the pediatric population, and fatalities are dramatic for families. It typically involves organic foreign bodies (mainly food) aspirated by children under three years old, usually at home or school. This review aimed to focus on the preventive measures around four actual cases of fatal foreign body aspiration, emphasizing the correct execution of the Heimlich maneuver and cardiopulmonary resuscitation, supervised mealtimes, and high-risk foods. (2) Methods: Four fatal cases of foreign body aspiration in children are presented here. The children were in a free environment, such as school, home, and the countryside, and were in the presence of teachers, parents, and a grandmother who did not supervise the children adequately. A literature review was performed via the MEDLINE database using the key terms: “foreign body aspiration,” “infant choking, 1.5 to 3 years,” “food and foreign body aspiration,” “common household,” “prevention of foreign body aspiration,” “guidelines,” “recommendations,” “training of caregivers (parents, educators),” “resuscitation,” “Heimlich maneuver,” and “disengagement of the upper airways.” We focused on the prevention of foreign body aspiration. (3) Results: a complete postmortem examination was performed. In three cases, the foreign bodies were food (mozzarella cheese, pear, or raw bean), while in one case, the foreign body was a pebble. (4) Conclusions: This review aimed to discuss recent scientific literature and provide a perspective on the benefits of a dedicated approach to the management of fatal foreign body aspiration in children by caregivers who usually have no experience with the best ways of supervising children in a safe environment, especially regarding the correct execution of resuscitation maneuvers, such as the Heimlich maneuver. Recommendation updates could improve healthcare quality in a pediatric setting and reduce medico-legal implications.

Dying for a Meal: An Integrative Review of Characteristics of Choking Incidents and Recommendations to Prevent Fatal and Nonfatal Choking Across Populations

Purpose The purpose of this study was to conduct an integrative review of original research, across adult populations relating to fatal or nonfatal choking on food, to understand ways to respond to and prevent choking incidents. Method Four scientific databases (CINAHL, Medline, Web of Science, and EMBASE) were searched for original peer-reviewed research relating to fatal or nonfatal choking on foods. Data were extracted on study characteristics; factors leading up to, events at the time of, and actions taken after the choking incident; and impacts of choking incidents. An integrative review of the findings across studies identified several risk factors and recommendations to reduce the risk of choking. Results In total, 52 studies met the criteria for inclusion in this review, of which 31 were quantitative, 17 were qualitative, and 4 were of a mixed methods design. Studies reported the observations and narratives of bystanders or researchers, or else were large-scale autopsy studies, and included both the general public and people at risk of dysphagia. A range of food types were involved, and several actions were reported in response to food choking. Strategies to reduce the risk of choking were identified in the studies and are presented in 5 main categories. Conclusions Factors leading up to choking incidents extend well beyond the individual to the environment for mealtimes; the provision of appropriate mealtime assistance and oral care; and regular monitoring of general health, oral health, and medications. Bystanders' increased awareness and knowledge of how to respond to choking are vital. The results of this review could be used to inform service policy and training, for individuals at risk of choking, the people who support them, and the general public. Further research is needed to explore choking prevention and airway protection in individuals with dysphagia. Supplemental Material https://doi.org/10.23641/asha.8121131.

[Swallowing disorders, training and assessment of geriatric practices]

In geriatrics, swallowing disorders are frequent, representing a daily source of anxiety for the nursing teams. Training in this area, aimed at caregivers in a long-stay care unit, has been developed based on an assessment of professional practices.

Effect of body position on relieve of foreign body from the airway

Foreign body airway obstruction (FBAO), or commonly known as choking, is an extremely dangerous event. The European Resuscitation Council recommends that back blows and abdominal thrusts should be performed for relieving FBAO in conscious adults. Reviewed here evidence suggests that applying a prone or a head-down position increases effectiveness of the above standard approaches to relieve obstruction, due to help of gravity.

Postoperative Airway Obstruction by a Bone Fragment

Postoperative airway obstructions are potentially life-threatening complications. These obstructions may be classified as functional (sagging tongue, laryngospasm, or bronchospasm), pathoanatomical (airway swelling or hematoma within the airways), or foreign body-related. Various cases of airway obstruction by foreign bodies have previously been reported, for example, by broken teeth or damaged airway instruments. Here we present the exceptional case of a postoperative airway obstruction due to a large fragment of the patient's maxillary bone, left accidentally in situ after transoral surgical tumor resection. Concerning this type of airway obstruction, we discuss possible causes, diagnosis, and treatment options. Although it is an exceptional case after surgery, clinicians should be aware of this potentially life-threatening complication. In summary, this case demonstrates that the differential diagnosis of postoperative airway obstructions should include foreign bodies derived from surgery, including tissue and bone fragments.
