Direct fetal injury due to airbag deployment and three-point restraint

A death due to faulty airbag system-case report

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.

Delayed Appearance of a Traumatic Fetal Intracranial Hemorrhage

Background

Fetal intracranial injury is a potentially devastating sequelae of maternal trauma, but there is little guidance regarding fetal evaluation in this setting.

Case

A 23-year-old woman at 27-week gestation was admitted after a high-speed motor vehicle accident. The initial obstetrical ultrasound was unremarkable, but persistently minimal fetal heart rate variability was observed. Ultrasound on day 3 after the accident showed an intracranial hyperechogenic lesion and subdural fluid collection. The neonate, following an uneventful birth at 39 weeks, had seizures and abnormal muscle tone. MRI was consistent with in utero intracranial hemorrhage.

Conclusion

Serial fetal imaging following maternal trauma, particularly when accompanied by abnormal fetal heart rate tracings, should be considered when fetal injury is a concern, even in the setting of a normal initial ultrasound.

Pregnancy and trauma: analysis of 139 cases

OBJECTIVE

The aim of this study was to examine the diagnoses and treatment methods and demographical and clinical characteristics of pregnant women who were exposed to trauma and in additon, review of the literature was carried out in this regard.

MATERIAL AND METHODS

One hundred thirty-nine pregnant women who presented at the Yüzüncü Yıl University between January 2006 and September 2009 with local or general body trauma complaints were analysed retrospectively.

RESULTS

The average age of the cases was 26.72±6.29 years and the age group ranging from 21-34 composed the majority. When they were studied according to their etiologies, falls during daily activities formed 43.9%. When they were analyzed in terms of their gestational weeks, 64.46% were in the 3(rd) trimester. Pregnant cases with trauma resulted in maternal (3 cases) and fetal (9 cases) loss. It was found that 19 cases who had imaging techniques involving radiation and whose gestation was continuing had a problem-free gestation period and healthy children.

CONCLUSION

It is mandatory to evaluate both mother and fetus together when trauma exposure is in question, the general well-being of the fetus should be provided and the mother should be informed about the presence of advanced trauma life support.

Car sunshade-induced craniofacial injury: a case report

Introduction

We report the case of a man who sustained a craniofacial injury after spontaneous lateral airbag deployment resulting in his face being struck by a car sunshade. This highlights the potential damage that can be caused by any object placed between a lateral airbag and a car occupant.

Case presentation

We report the case of a 33-year-old Caucasian man who was the driver in a frontal collision. He had opened the car sunshade and turned it 90° towards the left. As he was driving, he struck a bus, causing the driver's lateral airbag to spontaneously deploy. The airbag pushed the sunshade against his face and injured him.

Conclusions

Car sunshades can cause significant craniofacial injury. We suggest that sunshade design must be improved to reduce the risk of potential injuries to car occupants. We recommend a new, safer sunshade design.
