Abstract
Injuries due to automobile safety devices have been reported and we report a rare fatality due to a defective airbag system. A compact hybrid car driven by a 37-year-old male at moderate speed had crashed through an unprotected manhole. The car had moved around 200 m before it came to a halt. The passers-by had noticed that the driver was unconscious, partly leaning forward with an inflated airbag. He was pronounced dead on admission. The car had sustained minor indentation on front bumper. Autopsy revealed a circular perforated laceration on the neck associated with completely transected right carotid artery and partially transected jugular vein. There was a 2 × 2-cm cylindrical metal object lodged at C4-C5 vertebrae level, and the remaining part of this was retrieved during scene investigation and identified as a part of a metal canister in the inflator component of the airbag system. There was a perforation in the airbag which was similar in size to the retrieved foreign body. The cause of death was ascertained as hemorrhagic shock due to bleeding from ruptured neck vessels caused by primary shrapnel projected from the faulty airbag system. Following the incident, the manufacturers replaced faulty airbag systems in similar models. If abnormally fatal injuries are observed, a scene visit along with automotive expert opinion would provide valuable insight into the incident. Such information would alert the general public on regular screening of safety measures and prompt manufacturers to recall faulty products.

[PMID: 37575707 PMCID: PMC10423068 DOI: 10.7759/cureus.41808] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Accepted: 07/11/2023] [Indexed: 08/15/2023] Open
Abstract
BACKGROUND Dual airbags are required to be installed and available for use in all motor vehicles since 1997. The National Highway Traffic Safety Administration reported that 50,457 lives were saved by airbags from 1987 to 2017; however, airbag deployment can cause injuries, including thermal and chemical burns, hyperpigmentation, and dysaesthesia. There is little information available in the literature regarding differences in outcomes between promptly visiting a plastic surgeon and waiting for treatment, especially as an injury may not be immediately apparent or patients may not know that airbag burn injuries may be delayed in presenting. METHODS This is a retrospective cohort pilot study conducted among 14 patients who presented to a plastic surgeon between January 1, 2019 and June 30, 2022 owing to injuries from airbag deployment. An early visit was considered ≤30 days, and a late visit was >30 days. Other variables collected included age, sex, Fitzpatrick skin type, smoking status, comorbidities, type of injury, injury site, pain status, hyper/hypopigmentation, dysaesthesia, epithelialization, and improvements in pain, pigmentation, and dysaesthesia from treatment. RESULTS The mean age was 36.0 years (standard deviation (SD) 17.9). The majority were female (85.7%), non-smokers (87.5%), and not diabetic (75.0%). Only six patients (42.9%) visited their doctor within one month of injury. Most patients experienced dysaesthesia (85.7%) and pain (71.4%). Thirteen of the 14 patients had hyperpigmentation or hyperemia, and one had hypopigmentation. Full or slight epithelialization was seen in 35.7%, and nine of the 14 patients had no epithelialization. Ongoing issues were a factor for 64.3% of these patients; 42.9% had ongoing issues with hyperpigmentation. A full recovery was seen in 28.6% of the patients. The patients who saw the plastic surgeon by day 30 or less (early) from the time of injury had a 66.7% improvement in pigmentation and 33.3% resolution in pain. Of those who went to the surgeon beyond 30 days (late), 25% had improvement in pigmentation and 37.5% had resolution of pain. Improvement in dysaesthesia occurred in both groups, but those who saw the plastic surgeon early had 33.3% resolution, while 37.5% of those who went late improved. Of those who went late to the surgeon, only 12.5% had epithelialization, while 66.7% of those who went within 30 days showed signs of (full or slight) epithelialization. CONCLUSION Patients involved in motor vehicle collisions (MVCs) should be informed of the delayed fashion in which airbag burns can develop. An ostensibly mild burn may portend long-term consequences, especially if such injuries are not addressed in a prompt manner. Our study demonstrates how airbag burn injuries and their sequelae are best addressed with early care.

Abstract
INTRODUCTION Air bag deployment after high velocity trauma has been associated with burn injuries. So, we aimed to present a clinical case report associated with air bag deployment experienced by the author himself. CASE PRESENTATION The author was driving a hatchback car which collided head on with the high speeding vehicle from opposite direction. He sustained a burn injury around 4 × 3 cm in size in the flexor aspect of right forearm involving epidermis and some part of dermis which was superficial partial thickness in nature when the air bag deployment was observed at both the sides. Burn injury was healed with topical antibiotics and regular dressings with no any complications. DISCUSSION Air bag deployment has always been a safety measures for the road traffic injuries but the safety comes with a cost. It has been associated with burn injuries, especially chemical induced, thermal and frictional burns. Timely diagnosis of type of burn and intervention is required in order to minimize complications associated with burns. CONCLUSION Though burn injuries associated with air bag deployment cause less harm or complications, the companies making such commodities should explore the further options in order to develop burn injury free vehicle safety.

Abstract
CONTEXT Sodium azide is a highly toxic chemical. Its production has increased dramatically over the last 30 years due to its widespread use in vehicular airbags, and it is available for purchase online. Thus, accidental exposure to azide or use as a homicidal or suicidal agent could be on the rise, and secondary exposure to medical personnel can occur. No antidote exists for azide poisoning. We conducted a systematic review of azide poisoning to assess recent poisoning reports, exposure scenarios, clinical presentations, and treatment strategies. METHODS We searched both medical and newspaper databases to review the literature between 01/01/2000 and 12/31/2020, pairing the controlled vocabulary and keyword terms "sodium azide" or "hydrazoic acid" with terms relating to exposures and outcomes, such as "ingestion," "inhalation," "exposure," "poisoning," and "death." We included all peer-reviewed papers and news articles describing human azide poisoning cases from English and non-English publications that could be identified using English keywords. Data abstracted included the number, age, and gender of cases, mode of exposure, exposure setting, azide dose and route of exposure, symptoms, outcome, and treatment modalities. RESULTS We identified 663 peer-reviewed papers and 303 newspaper articles. After removing duplicated and non-qualifying sources, 54 publications were reviewed describing 156 cases, yielding an average of 7.8 reported azide poisoning cases per year. This rate is three times higher than in a previous review covering the period of 1927 to 1999. Poisoning occurred most commonly in laboratory workers, during secondary exposure of medical personnel, or from a ripped airbag. Hypotension occurred commonly, in some cases requiring vasopressors and one patient received an intra-aortic ballon pump. Gastric lavage and/or activated charcoal were used for oral azide ingestion, and sodium nitrite, sodium thiosulfate, and/or hydroxocobalamin were used in severely poisoned patients. CONCLUSIONS Recent increases in azide poisoning reports may stem from greater commercial use and availability. Treatment of systemic poisoning may require aggressive hemodynamic support due to profound hypotension. Based on mechanistic considerations, hydroxocobalamin is a rational choice for treating azide poisoning.

Abstract
The advantages of airbags in reducing the rate of severe injuries and fatalities in motor vehicle crashes are well known but the physical act of airbag deployment can lead to injury to the passenger and the spectrum of airbag trauma resulting from deployment of vehicle airbags has been extensively reported. We present the first reported case of a pediatric burn injury resulting from the accidental deployment of an airbag in an aircraft. A four-year-old female child sustained injuries to the left side of her face and body while she was aboard a stationary airplane and the airbag concealed within the seat belt of her airplane seat unexpectedly and inexplicably deployed just before departure. We are presenting the case to increase awareness of the possibility of this injury in aircraft and to enable minimization of such accidents as well as help establish protocols for dealing with such mishaps if there were to happen.

Abstract
Airbags significantly reduce fatalities and injuries in automobile crashes, but they have been found to be associated with burns. Specifically, airbags can cause burns through thermal or chemical mechanisms and commonly affect the arms, hands, face, and eyes. While most airbag-induced burns are minor, some may cause unfavorable outcomes. Our study aimed to systematically review airbag-induced burns to assess etiology, type, and treatment of these injuries. A systematic review of case reports pertaining to airbag-induced cutaneous and ocular burns was conducted. Data reviewed included type/location of burns, severity of burn, total number of patients, treatment, complications, and outcome after treatment. We identified 21 case reports that met our inclusion criteria with a total of 24 patients reported in the studies. Of the studies identified, 38% were chemical burns and 25% were thermal burns. Most commonly the upper extremities were burned in 42% of cases, followed by eyes (25%) and face (21%). Most burns identified were superficial partial thickness (58%). Treatment outcomes were good for cutaneous burns, with 95% healing without complication. However, ocular injuries lead to permanent impaired eye function in 71% of cases. In our systematic review, we highlighted the common risk factors, prognosis, and treatment for thermal, chemical, and ocular burns. Airbag-induced burns have a relatively good prognosis but must be recognized and treated immediately to reduce the risk of serious sequelae.

Abstract
Thousands of people are injured in motor vehicle collisions daily and the mandated installation of airbags protects passengers but can also cause injuries from deployment including cutaneous burns. We sought to characterize the patterns and outcomes of burns resulting from airbag deployment by performing a retrospective review of all patients evaluated by the burn service from May 1, 2015 to April 30, 2019. Inclusion criteria were patients of all ages with burn injuries related to airbag deployment. Demographic data, burn characteristics, and outcomes were reviewed. Seventeen patients met the inclusion criteria: 82.4% female and 17.6% male. The average age was 40.4 years. Fifteen patients had second-degree and two had third-degree burns. The average TBSA was 0.45%. The hands or upper extremity (88%) were most often injured, but there were two chest, one neck, and one anterior thigh burns. Eight patients suffered multiple burns. Burn etiology (chemical vs thermal) was often not specified. No patients required hospitalization or surgical intervention, and all wounds healed with wound care. The average time to re-epithelialization was 11 days. Although airbags prevent mortality and serious injury, the exothermic chemical reaction that inflates the airbag is responsible for deployment-related burns. Since there is a chemical and thermal component, all airbag-related burns should undergo chemical decontamination on the initial presentation. Burns related to airbag deployment tend to be small and do not require grafting; however, patients suffer from associated pain, scarring, and burn management can be a financial and time burden to the patient.

Abstract
There are many chemicals that can cause burns. Although they are generally acidic and basic in nature, there are more than one million known chemical compounds, of which 300 have been declared highly hazardous chemical substances by the National Fire Protection Society. Chemical burns account for approximately 10.7% of all burn injuries and 30% of deaths because of burns. Chemicals can be classified as acid, alkali, organic, and inorganic compounds. Acids act by denaturing and coagulating proteins. Alkaline burns cause deeper burns than acid burns.

Abstract
The performance of airbag and its deployment are based on a fast exothermic-chemical reaction. The hot gas resulting from the chemical reaction which results in airbag deployment can cause thermal damage and skin burning for the car passenger. The thermal burns due to airbags are of two types: burns due to direct contact with the airbag surface and burns resulting from exposure to the hot gas leaving the deflation vents of the airbag. In this research, for experimental study of the burns resulting from exposure of the skin to airbag, using infrared thermography, the extent of temperature rise of the airbag surface was detected and measured from the zero moment of its inflation. Next, using Henriques equation, the extent of thermal damage caused by airbag deployment and its resulting burn degree was calculated. The results indicated that during the inflation of airbag, the maximum temperature of its surface can be 92 °C ± 2 °C. Furthermore, if the vehicle's safety system functions within the predicted time intervals, the risk of thermal damage is virtually zero. However, if even a slight delay occurs in detachment of the passenger's head and face off the airbag, second- and third-degree burns could develop.

Abstract
This study aimed to verify the opinion of speech-language pathology teachers and undergraduate students about human accidents and investigate if they are seeking for knowledge and competence in this area. Fifty-two teachers and 95 students from 3 public and 3 private universities in São Paulo took part in this study. Data were collected by means of a questionnaire. According to the participants, accidents are unexpected events that cause physical, functional, emotional and social consequences. Inattentiveness, incaution as well as mental and physical fatigue are factors that contribute to accidents. The speech-language therapist, the physical therapist, the occupational therapist and the physicians were considered the most indicated professionals for correcting the sequels caused by external aggressions. They were also considered the most indicated for carrying out educational actions for the prevention of accidents in form of orientation and lectures for the population of the educational and health units. Teachers and students recognize the importance of the subject, a fact that will help optimizing the educational actions toward accident prevention and introducing new actions and research projects in the universities for improving the competences in this field of knowledge.

Abstract
With the number of vehicles on the road increasing, the safety aspects of motoring are becoming a progressively more important consideration in health care provision and policy. Airbags are a relatively new introduction into our vehicles. Unlike other mechanisms such as seat belts, they offer protection without the need for any action on the part of the occupant. However, the necessarily violent nature of their deployment has led to the emergence of patterns of injury as a direct result. Knowledge of the potential dangers posed by these systems is useful both for emergency department physicians in order to prevent important injuries being missed, and for car manufacturers using increas ingly modern technology to design more efficient mechanisms. We undertook a review of the current literature to ascertain the spectrum of injuries that have been attributed to the use of airbags, while putting this into the wider context of their protective contribution.
