Other intra-abdominal and retroperitoneal injuries may also occur, which are more readily diagnosed on computed tomography scan or focused abdominal utlrasound when available, but are no more frequent in patients with the seat-belt sign than those without. The seat-belt sign is indicative of an increased risk of intestinal injury, which is difficult to detect with no single test providing reliable diagnosis. In the 25 patients with intra-abdominal injuries, there were 10 hepatic, 8 splenic, 9 intestinal and 4 retroperitoneal injuries. The proportion of intestinal injuries in patients with and without seat-belt sign were 9/60 and 0/39, respectively (P = 0.01). Patients were identified from International Classification of Disease-9 codes for abdominal wall and intra-abdominal injuries. Seat Belts / adverse effects Sensitivity and Specificity. Seatbelt sign following blunt trauma is associated with increased incidence of abdominal injury Am Surg. Spectrum of abdominal injuries in a population with high usage of three-point restraints.Ī retrospective chart review was conducted in an adult tertiary-referral hospital from January 1992 to August 1998. The use of lap belts has, however, been associated with a constellation of abdominal injuries, which has been termed 'the seatbelt syndrome.'. Prevalence of intestinal injuries in patients with seat-belt sign and 3. Prevalence of seat-belt sign in motor vehicle accident victims with abdominal injuries 2. Routine laparotomy or mandatory evaluation by specific diagnostic tests is not justified rather, a high index of suspicion with a low threshold for appropriate diagnostic evaluation and/or surgical exploration should be maintained for the optimal management of such patients.To report on: 1. The presence of the SBM sign should alert the physician to the high likelihood of specific internal injuries. There was a near 4-fold increase in thoracic trauma (22.5% versus 6% P=0.01) and a near 8-fold increase in intra-abdominal trauma (23% versus 3% P < 0.0001) between the groups of patients with and without SBMs. Three patients were found to have myocardial contusion, and 10 patients had intra-abdominal injuries (predominantly bowel and mesenteric lacerations) requiring laparotomy. Google Scholar Christophi C, McDermott FT, McVey I, Hughes ES. Seatbelt sign following blunt trauma is associated with increased incidence of abdominal injury. The seatbelt sign is the bruising of the chest or abdominal wall with the diagonal or horizontal strap of the seatbelt 32, 33.The two point lap belts cause injuries to the abdomen, pelvis, and lumbar spine. The patient had abdominal tenderness and guarding. Despite that seatbelts restrain the body to the car seat the deceleration of the body may cause seatbelt-related injuries. Abdominal distention after trauma typically indicates severe hemorrhage (2 to 3 L), but distention may not be apparent even in patients who have lost several units of blood. No significant neck injuries were detected. A 30-year-old male driver with an abdominal seat belt sign (A) who had a laparotomy (B). Blunt trauma may cause ecchymosis (eg, the transverse, linear ecchymosis termed seat belt sign), but this finding has poor sensitivity and specificity. Of patients with SBMs, 9 per cent had neck bruises, 32 per cent had chest bruises, 40 per cent had abdominal bruises, and 19 per cent had bruises in multiple sites. The injuries of these 77 patients were compared with the injuries of belted patients without an SBM sign. study included consecutive patients involved in road traffic accidents who were admitted at an academic Level I trauma center. Of 650 car occupants, 410 (63%) were restrained and 77 (12%) had a SBM across the abdomen, chest or neck. Skin bruise corresponding to the site of the seat belt is known as the 'seat belt mark' (SBM) sign and is associated with a high incidence of significant organ injuries. The prospective study included consecutive patients involved in road traffic accidents who were admitted at an academic Level I trauma center. The objective of this study was to find the incidence of surgically correctable injuries in belted car occupants with a SBM sign and to define strategies of early detection and treatment of such injuries. No study has yet defined the exact incidence of injuries requiring intervention at the presence of this sign. Skin bruise corresponding to the site of the seat belt is known as the "seat belt mark" (SBM) sign and is associated with a high incidence of significant organ injuries. The use of seat belts is shown to cause a specific pattern of internal injuries.
