Non-fatal injuries sustained by seatbelt wearers: a comparative study. (1/363)

The injuries sustained by 969 drivers and front-seat passengers in road-traffic accidents were studied. Altogether 196 (20-2%) of the drivers and passengers were wearing seat belts and 773 (79-8%) were not. The injuries among the two groups differed greatly in both severity and distribution. A total of 54 (27-6%) of the seatbelt wearers sustained one or more fractures compared with 300 (38-8%) of the non-wearers, and 18 (9-2%) of the seatbelt wearers were severely injured compared with 300 (38-8%) of the non-wearers. Soft-tissue injuries to the face were sustained by only 29 (14-8%) of the seatbelt wearers compared with 425 (55%) of the non-wearers. Since wearing seatbelts may become compulsory, the type and pattern of injuries to be expected in wearers should be appreciated.  (+info)

Prospective, randomized comparison of epidural versus parenteral opioid analgesia in thoracic trauma. (2/363)

OBJECTIVE: To evaluate systemic versus epidural opioid administration for analgesia in patients sustaining thoracic trauma. SUMMARY BACKGROUND DATA: The authors have previously shown that epidural analgesia significantly reduces the pain associated with significant chest wall injury. Recent studies report that epidural analgesia is associated with a lower catecholamine and cytokine response in patients undergoing elective thoracotomy compared with patient-controlled analgesia (PCA). This study compares the effect of epidural analgesia and PCA on pain relief, pulmonary function, cathechol release, and immune response in patients sustaining significant thoracic trauma. METHODS: Patients (ages 18 to 60 years) sustaining thoracic injury were prospectively randomized to receive epidural analgesia or PCA during an 18-month period. Levels of serum interleukin (IL)-1beta, IL-2, IL-6, IL-8, and tumor necrosis factor-alpha (TNF-alpha) were measured every 12 hours for 3 days by enzyme-linked immunosorbent assay. Urinary catecholamine levels were measured every 24 hours. Independent observers assessed pulmonary function using standard techniques and analgesia using a verbal rating score. RESULTS: Twenty-four patients of the 34 enrolled completed the study. Age, injury severity score, thoracic abbreviated injury score, and length of hospital stay did not differ between the two groups. There was no significant difference in plasma levels of IL-1beta, IL-2, IL-6, or TNF-alpha or urinary catecholamines between the two groups at any time point. Epidural analgesia was associated with significantly reduced plasma levels of IL-8 at days 2 and 3, verbal rating score of pain on days 1 and 3, and maximal inspiratory force and tidal volume on day 3 versus PCA. CONCLUSIONS: Epidural analgesia significantly reduced pain with chest wall excursion compared with PCA. The route of analgesia did not affect the catecholamine response. However, serum levels of IL-8, a proinflammatory chemoattractant that has been implicated in acute lung injury, were significantly reduced in patients receiving epidural analgesia on days 2 and 3. This may have important clinical implications because lower levels of IL-8 may reduce infectious or inflammatory complications in the trauma patient. Also, tidal volume and maximal inspiratory force were improved with epidural analgesia by day 3. These results demonstrate that epidural analgesia is superior to PCA in providing analgesia, improving pulmonary function, and modifying the immune response in patients with severe chest injury.  (+info)

Injuries to riders in the cross country phase of eventing: the importance of protective equipment. (3/363)

OBJECTIVES: To determine the distribution of injuries in the eventing discipline of equestrian sports and the effectiveness of the protective equipment worn. METHODS: Data on all injuries sustained in the cross country phase over fixed obstacles were collected from 54 days of competition from 1992 to 1997. This involved 16,940 rides. RESULTS: Data on a total of 193 injuries were collected, which included two deaths. This represents an injury rate of 1.1%. Head and facial injuries represented the largest group (31%), with one third of these requiring treatment in hospital. All riders were wearing protective helmets and body protectors. CONCLUSIONS: Eventing is one of the most dangerous equestrian sports. Improved protective equipment, which is mandatory for 1999, should reduce the severity of these injuries.  (+info)

Selective activation of the K(+)(ATP) channel is a mechanism by which sudden death is produced by low-energy chest-wall impact (Commotio cordis). (5/363)

BACKGROUND: Sudden death due to relatively innocent chest-wall impact has been described in young individuals (commotio cordis). In our previously reported swine model of commotio cordis, ventricular fibrillation (with T-wave strikes) and ST-segment elevation (with QRS strikes) were produced by 30-mph baseball impacts to the precordium. Because activation of the K(+)(ATP) channel has been implicated in the pathogenesis of ST elevation and ventricular fibrillation in myocardial ischemia, we hypothesized that this channel could be responsible for the electrophysiologic findings in our experimental model and in victims of commotio cordis. METHODS AND RESULTS: In the initial experiment, 6 juvenile swine were given 0.5 mg/kg IV glibenclamide, a selective inhibitor of the K(+)(ATP) channel, and chest impact was given on the QRS. The results of these strikes were compared with animals in which no glibenclamide was given. In the second phase, 20 swine were randomized to receive glibenclamide or a control vehicle (in a double-blind fashion), with chest impact delivered just before the T-wave peak. With QRS impacts, the maximal ST elevation was significantly less in those animals given glibenclamide (0.16+/-0.10 mV) than in controls (0.35+/-0.20 mV; P=0.004). With T-wave impacts, the animals that received glibenclamide had significantly fewer occurrences of ventricular fibrillation (1 episode in 27 impacts; 4%) than controls (6 episodes in 18 impacts; 33%; P=0.01). CONCLUSIONS: In this experimental model of commotio cordis, blockade of the K(+)(ATP) channel reduced the incidence of ventricular fibrillation and the magnitude of ST-segment elevation. Therefore, selective K(+)(ATP) channel activation may be a pivotal mechanism in sudden death resulting from low-energy chest-wall trauma in young people during sporting activities.  (+info)

Management of penetrating cervicomediastinal venous trauma. (6/363)

OBJECTIVES: to evaluate the results of management of penetrating cervicomediastinal venous trauma. DESIGN: retrospective study. Materials forty-nine consecutive patients with cervical and thoracic venous injuries treated at a tertiary hospital between 1991 and 1997. Method patients identified from a computerised database and data extracted from case records. RESULTS: forty-five patients were male and the mean age was 25.3 years. Forty injuries were due to stabs and 9 to gunshots. 22 patients were shocked, 25 actively bleeding and 31 were anaemic. Veins injured were internal jugular in 25, subclavian in 15, brachiocephalic in 6, and superior vena cava in 3. Injured veins were ligated in 25 cases and repaired by lateral suture in 22. No complex repairs were performed. There were 8 perioperative deaths and 5 cases of transient postoperative oedema. Venous ligation was not associated with increased risk of postoperative oedema. CONCLUSIONS: ligation is an acceptable form of treatment of cervicomediastinal venous injuries in the presence of haemodynamic instability, or where complex methods of repair would otherwise be necessary.  (+info)

Complications of tube thoracostomy in trauma. (7/363)

OBJECTIVE: To assess the complication rate of tube thoracostomy in trauma. To consider whether this rate is high enough to support a selective reduction in the indications for tube thoracostomy in trauma. METHODS: A retrospective case series of all trauma patients who underwent tube thoracostomy during a 12 month period at a large UK teaching hospital with an accident and emergency (A&E) department seeing in excess of 125,000 new patients/year. These patients were identified using the hospital audit department computerised retrieval system supplemented by a hand search of both the data collected for the Major Trauma Outcome Study and the A&E admission unit log book. The notes were assessed with regard to the incidence of complications, which were divided into insertional, infective, and positional. RESULTS: Fifty seven chest drains were placed in 47 patients over the 12 month period. Seven patients who died within 48 hours of drain insertion were excluded. The commonest indications for tube thoracostomy were pneumothorax (54%) and haemothorax (20%); 90% of tubes were placed as a result of blunt trauma. The overall complication rate of the procedure was 30%. There were no insertional complications and only one (2%) major complication, which was empyema thoracis. CONCLUSION: This study reveals no persuasive evidence to support a selective reduction in the indications for tube thoracostomy in trauma. A larger study to confirm or refute these findings must be performed before any change in established safe practice.  (+info)

Defining GERD. (8/363)

"It is not the death of GERD that I seek, but that it turns from its evil ways and follows the path of righteousness." The reflux world is fully aware of what GERD is and what GERD does. What the world does not know, however, is the answer to the most important yet least asked question surrounding GERD's raison-d'etre: Why is GERD here and why do we have it? What GERD is: abnormal gastric reflux into the esophagus that causes any type of mischief. What GERD does: causes discomfort and/or pain with or without destroying the mucosa; causes stricture or stenosis, preventing food from being swallowed; sets the stage for the development of esophageal adenocarcinoma; invades the surrounding lands to harass the peaceful oropharyngeal, laryngeal and broncho-pulmonary territories; reminds us that we are not only human, but that we are dust and ashes. Why GERD is here: We propose three separate and distinct etiologies of GERD, and we offer the following three hypotheses to explain why, after 1.5 million years of standing erect, we have evolved into a species (specifically Homosapiens sapiens) that is destined to live with the scourge of GERD. Hypothesis 1: congenital. The antireflux barrier, comprising the smooth-muscled lower esophageal sphincter, the skeletal-muscled right crural diaphragm and the phreno-esophageal ligament does not completely develop due to a developmental anomaly or incomplete gestation. Hypothesis 2: acute trauma: The antireflux barrier in adults suffering acute traumatic injury to the abdomen or chest is permanently disrupted by unexpected forces, such as motor vehicle accidents (with steering wheel crush impact), blows to the abdomen (from activities such as boxing, etc.), heavy lifting or moving (e.g., pianos, refrigerators) or stress positions (e.g., hand stands on parallel gym bars). The trauma creates a hiatal hernia that renders the antireflux mechanism useless and incapable of preventing GERD. Hypothesis 3: chronic trauma: The antireflux barrier in children and adults is gradually weakened over time as a result of chronic straining to defecate and straining in an unphysiologic position, both of which stem from our modern day habits of eating a low-fiber diet and living on the high-seated toilet. We suggest that the chronic traumatic hiatal hernia is (a) the cause of more than 90 percent of the GERD that stalks the Western world; (b) is a direct result of abandoning the popular and worldwide practice of squatting to socialize, eat and defecate; and (c) is our just reward for adopting the "civilized" high sitting position on chairs and modern toilets.  (+info)
