[Polytrauma in cyclists. Incidence, etiology, and injury patterns].

BACKGROUND: In our region we have noticed an increasing number of cyclists and consequently a rise in bicycle-related accidents in recent years. A large number of our polytraumatized patients are victims of bicycle-related accidents. MATERIAL AND METHODS: Retrospectively we analyzed the data of our polytraumatized patients recorded between May 2003 and June 2004 for bicycle-related injuries. Of 153 polytraumatized patients treated in our emergency room 32 were cyclists (21%). The average age of our polytraumatized cyclist was 42 years, and the male-to-female ratio was 1:1. RESULTS: The median score on the Glasgow Coma Scale (GCS) after the accident was 8 (min. 3, max. 15), the median Injury Severity Score (ISS) was 24 (min. 18, max. 41), and the median Polytrauma Score (PTS) was 23 (min. 14, max. 51). A total of 30 patients (94%) suffered a head injury; in 28 patients (88%) the head injury was the leading diagnosis. The median score on the Abbreviated Injury Scale (AIS) Head was 4 (min. 1, max. 5), the AIS Thorax 3 (min. 2, max. 4), and the AIS Extremities 3 (min, 2, max. 5). Our data were also compared with the official injury statistics of the region and the current literature. CONCLUSION: The most frequent and most severe injury was the head injury (94%). Of the 32 polytraumatized cyclists 30 did not wear a helmet. Successful prevention could possibly be practiced if all cyclists wear helmets.

Relative bradycardia in patients with isolated penetrating abdominal trauma and isolated extremity trauma.

A relative bradycardia is sometimes seen in patients with hemorrhagic shock. The phenomenon of relative bradycardia in civilian patients with isolated penetrating abdominal trauma and isolated severe extremity trauma who presented to an urban trauma center was studied retrospectively. Relative bradycardia was defined as a pulse rate of less than 100 with a concomitant systolic blood pressure of less than 100 mm Hg. There were 256 patients with isolated penetrating abdominal trauma and 938 patients with isolated severe extremity trauma. The incidence of relative bradycardia was 3.1% (eight of 256) in the group with abdominal trauma and 1.8% (17 of 938) in the group with extremity trauma. A pulse rate less than 100 was documented in 35.2% of all patients presenting with a systolic blood pressure less than 100 mm Hg (25 of 71). A pulse rate of less than 100 was documented in 45.8% of all patients presenting with a systolic blood pressure less than 90 mm Hg (11 of 24). No increased mortality was seen in the patients who evidenced relative bradycardia. The effect of intraperitoneal bleeding on the normal tachycardic response to hemorrhage also was studied. After controlling for volume status using various operational definitions of shock, no statistically significant (P less than .01) difference in pulse rates was noted between patients with isolated penetrating abdominal trauma and isolated extremity trauma. This result suggests that the previously theorized vagal-mediated bradycardia unique to intraperitoneal bleeding may not exist.

An epidemiological view of vascular trauma in Western Australia: a 5-year study.

BACKGROUND: Although Australia encounters vascular injury less frequently than countries such as the USA, the predominance of blunt trauma with associated complex injuries continues to pose problems for clinicians. The present paper reviews Royal Perth Hospital's experience of vascular trauma epidemiology. METHODS: All individuals who presented to the Royal Perth Hospital (RPH) with a vascular injury between August 1994 and January 2000 were identified from a prospective trauma database. Injuries were classified using the Abbreviated Injury Score (AIS 90 code). The five major vascular injury groups as defined by AIS 90 (neck, thorax, abdomen, upper limb and lower limb) were analysed in turn to determine which injuries were most frequent, what the common causes were, effects of alcohol and drugs, common associated injuries, investigations performed, mortality, proportion of rural vascular trauma with transfer details and lengths of hospital stay. RESULTS: During the study period, 153 patients (1% of total trauma workload) sustained 175 vascular injuries. The commonest causes of injury for each group were stabbing (neck and lower limb), motor vehicle accident (thorax and abdomen) and work machinery (upper limb). Mortality was highest for thoracic injury (14/32; 44%) followed by abdominal injury (10/29; 34%). The ratio of blunt to penetrating vascular trauma is high and is increasing, as is the ratio of truncal to extremity vascular trauma. The most common artery-vein combination injury was to the femoral vessels. CONCLUSIONS: The injury patterns emerging from the present study will hopefully help all medical personnel to recognize the potential for vascular injury in a trauma setting.

[Macroreplantation of the upper extremity. Report of experiences based on 4 cases].

Amputation of an extremity frequently represents a life-threatening injury and is accompanied by volume deficiency shock through loss of blood. The loss of an arm leads to diability and thus impairs the physical and psychic integrity of the person concerned. This contribution presents 4 cases with macroamputation at the upper extremity, 3 of them involving successfully performed reimplantations. After a historic survey, these cases are used as a basis for discussing the establishment of the indication, the procedure, the complications and the results of the reimplantation.

Sports related injuries in Scottish adolescents aged 11-15.

OBJECTIVES: To measure the age and sex distribution of self reported sports and leisure injuries in a 12 month retrospective recall period among a representative national sample of Scottish adolescents, and to examine the characteristics (gender, age, handedness, and level of sports participation) of sports related injuries in relation to injuries sustained during other activities. DESIGN/SETTING: Self completion questionnaire survey administered in schools during April-June 1994. SUBJECTS: 4710 pupils aged 11, 13, and 15 years drawn from a representative sample of 270 classes with returns from 224 classes (83% completion rate). RESULTS: 42.1% of the sample reported a medically attended injury. These were significantly more frequent among boys but there were no significant age differences in overall frequency of injury. Sport related injuries accounted for 32.2% of all medically attended injuries. As with all injuries, frequency was greater in boys than girls at all ages, and there are differences in the pattern of lesions in sports and nonsports injuries. Lower limb injuries were more frequent than upper limb injury in sports (57.6 v 23.9%), whereas there were no differences in non-sports injuries (31.5 v 31.3%). Age and handedness differences in sports injury rates were also identified. High sports participation was significantly associated with a higher risk of injury in general and sports related injury in particular. CONCLUSION: Age, gender, handedness, and level of sports participation have been shown to be implicated in differential risk of sports related injury. Reducing sports injury among adolescents should be a priority, but research into the injury profiles of different sports is needed before detailed injury prevention strategies can be developed.
