Delayed hemopericardium after penetrating chest trauma: thoracoscopic pericardial window as a therapeutic option.

A 41-year-old male developed a hemothorax after sustaining a stab wound in the right chest. The patient was managed conservatively with thoracostomy tube drainage for 3 days and was subsequently discharged home. Two weeks later the patient returned to the hospital with pleuritic chest pain and shortness of breath.

Thoracic packing for uncontrolled bleeding in penetrating thoracic injuries.

We present a series of three patients who suffered penetrating thoracic injury, and in whom thoracic packing was used as a life-saving procedure. Survival among these patients paralleled the severity and extent of the original injuries. Restriction of cardiac filling and lung expansion are potential deterrents from using this technique; however, its use seems to be a valid adjunct, especially in the setting of chest wall bleeding coming from the intercostal arteries.

The effect of trauma program registry on reported mortality rates.

Background: This study assesses the relationship that the brand of trauma program registry (TPR) has on mortality rate (MR) in the reports prepared by the American College of Surgeons Committee on Trauma (ACSCOT) trauma center (TC) site surveyors.

Methods: Data from 242 ACSCOT adult TC survey reports (88 Level I, 115 Level II, and 39 Level III) were analyzed for annual trauma volume, injury severity score (ISS), MR, and TPR. Six TPR (A through F) were identified; group F was a composite of several infrequently used TPRs.

Gunshot wounds to the neck.

Gunshot wounds to the neck are diagnostically and therapeutically challenging cases. We report such a case with vascular and neurologic injuries and describe the therapeutic options. Initial treatment is aimed at hemodynamic stabilization.

Mathematical modeling to define optimum operating room staffing needs for trauma centers.

Background: Level II trauma centers may be verified (1999, American College of Surgeons Committee on Trauma) with an on-call operating room team if the performance-improvement program shows no adverse outcomes. Using queuing and simulation methodology, this study attempted to add a volume guideline.

Study Design: Data from 72 previously verified trauma centers identified multiple demographic factors, including specific information about the first trauma-related operation that was done between 11:00 PM and 7:00 AM each month for 12 consecutive months.

Accuracy of administrative data in trauma: splenic injuries as an example.

Background: Accurate data are needed to evaluate clinical outcomes, therapeutic modalities, and quality of care in trauma. Administrative data, usually used for billing, have been used to evaluate performance and assess therapy in other medical specialties. This study was performed to determine whether administrative databases are accurate in the recording of information about trauma patients with splenic injuries.

Acinetobacter calcoaceticus pneumonia and the formation of pneumatoceles.

Pneumatoceles are cystic lesions of the lungs often seen in children with staphylococcal pneumonia and positive-pressure ventilation. Acinetobacter calcoaceticus is an aerobic, short immobile gram-negative rod, or coccobacillus, which is an omnipresent saprophyte. The variant anitratus is the most clinically significant pathogen in this family, usually presenting as a lower respiratory tract infection.

Blunt thoracic aortic injuries: initial evaluation and management.

In at least one large study, the average time from arrival at the emergency department to arrival in the operating room was nearly 6 hours. That 30% of survivors will die in the same amount of time underscores the need for rapid diagnosis and treatment. In blunt thoracic aortic injury, beta-blockers have been shown to reduce the incidence of rupture, and their use is rarely contraindicated.

The natural history of extremity venous repair performed for trauma.

Surgical repair of extremity venous injuries remains controversial. Literature supports both ligation and repair when analyzed for functional recovery. However, few studies review the natural history of venous repair for trauma.

Surgical management of chronic pain from chronic pancreatitis.

Chronic pain from chronic pancreatitis remains a difficult clinical problem. We present the results of surgical attempts to control this pain. For the past 3 years, all patients with chronic pancreatitis and pain requiring high-dose narcotics or hospitalization for pain control were evaluated by the following algorithm.

Firearm injury in Orleans parish: a 24-month perspective.

This study is a retrospective review of all gunshot wounds treated at Charity Hospital, the Orleans Parish designated trauma center, for the 24-month period from November 1993 to November 1995. Its purpose was to define the magnitude of firearm injury in the parish and the impact on the health care system. One-thousand-six-hundred-sixty-nine gunshot wounds were analyzed.

Timing and dosage of postoperative radiotherapy for squamous cell carcinoma of the upper aerodigestive tract.

Seventy patients who received postoperative irradiation (PI) after curative surgery for stage III or IV squamous cell carcinoma of the upper aerodigestive tract were studied retrospectively to compare the rate of local and regional recurrence (LRR) and the effect of total dose on LRR rate in patients irradiated timely (n = 40) with those who were not (n = 30). Overall, the LRR rate was higher when PI was delayed than when timely (37% vs 20%). No advantage resulted from increasing total dose when PI was delayed; the LRR rate in the primary site and upper neck was 18% with less than 60 Gy and was 26% with 60 Gy or more; the LRR rate in the lower neck was 13% with 50 Gy or less and was 14% with more than 50 Gy.

Early evacuation of clotted blood in hemothorax using thoracoscopy: case reports.

Hemothorax complicated by clotting of the blood is traditionally treated with thoracotomy. Successful treatment using early thoracoscopy in two patients is described. A third patient, in whom thoracoscopic evacuation failed, is also discussed.

Trauma care in Louisiana: problems and possibilities.

Trauma is a major national health problem and is the leading cause of death for Americans under the age of 44. Data about the impact of trauma in Louisiana is lacking and there are currently no statewide initiatives for improving trauma care. Louisiana State University Medical Center Hospital in Shreveport (LSUMCH) has recently been licensed and designated by the state as a "primary trauma center.

Duplex ultrasonography versus arteriography in the diagnosis of arterial injury: an experimental study.

Duplex ultrasonography (DUS) and arteriography (ART) were evaluated using an experimental model of arterial trauma in order to determine the accuracy of DUS compared with ART and to define the characteristic ultrasonographic features of arterial injuries. Occlusions (n = 19), blunt injuries (n = 24), lacerations (n = 25), arteriovenous fistulae (n = 13), or no injuries (sham, n = 19) were surgically created in the femoral and carotid arteries of 25 dogs. Following closure of the incisions, DUS was performed and interpreted by a staff vascular surgeon without knowledge of the presence or type of injury.

Enterocutaneous fistulas following laparotomy for trauma.

Enterocutaneous fistulas (ECF) are recognized complications of various bowel diseases. Trauma is reported as a rare cause of ECF. ECF following laparotomy for abdominal injury was studied in 15 patients to determine whether traditional principles of management for ECF are applicable in posttraumatic ECF.

Whipple procedure for trauma: is duct ligation a safe alternative to pancreaticojejunostomy?

The use of pancreatic duct ligation (DL) during a Whipple procedure for trauma has been reported but not analyzed. We reviewed 13 cases of DL and compared the results with that reported for the Whipple procedure for trauma with pancreaticojejunostomy (PJ). The mortality rate of DL was 53.

Management of penetrating colon injuries. A prospective randomized trial.

Fifty-six patients with penetrating colon injuries were entered into a randomized prospective study. Management of the colon injury was not dependent on the number of associated injuries, amount of fecal contamination, shock, or blood requirements. Twenty-eight patients were treated with primary repair or resection and anastomosis and 28 patients were treated by diversion (24 colostomy, 3 ileostomy, 1 jejunostomy).

The use of segmental anatomy for an operative classification of liver injuries.

There is no universally accepted standard classification for liver injuries, and thus accurate comparison of reports on the subject is impossible. Most published reports on liver trauma suggest that both morbidity and mortality have a linear correlation with not only the amount of liver parenchyma injured but also with the magnitude of the surgical intervention. The exceptions are retrohepatic vein injuries, which have a mortality independent of associated parenchymal injury but should be integrated in any classification of liver injury.

The use of serum amylase and lipase in evaluating and managing blunt abdominal trauma.

In order to determine the usefulness of serum amylase and lipase in the initial evaluation and subsequent management of blunt abdominal trauma (BAT) patients, we collected serum amylase and lipase on 85 consecutive BAT patients at admission, hospital day 1, hospital day 3, and hospital day 7. Only one patient had a pancreatic injury. A total of 45 patients (53%) had at least one enzyme abnormality during the study.

A new technique for exposure of injuries at the confluence of the retrohepatic veins and the retrohepatic vena cava.

Because of difficulties in rapid exposure and control, injuries of the retrohepatic veins and retrohepatic vena cava continue to have mortality rates approaching 100%. Current strategies include shunt and finger fracture techniques, with controversy continuing over the optimal approach. We describe a new technique which involves mobilization of the liver by transecting the superhepatic vena cava, and affords a posterior approach to these injuries.

Retrohepatic vein injuries: experience with 20 cases.

The mortality for injury of the retrohepatic veins is reported to vary from 50 to 100%. The use of hepatic bypass techniques, introduced in the 1960's, has not significantly decreased this mortality. We reviewed our experience with liver injuries over a 5-year period from 1982 to 1987 to determine our results with these particular injuries.

Surgical management of the acutely obstructed colon. A review of 127 cases.

The surgical results in 127 cases of acute obstruction of the colon are presented. Carcinoma continues to account for the overwhelming number of cases, and there has been no appreciable change in the site of obstruction or age groups affected. In the current study, the overall mortality rate in patients with acute obstruction from all causes was 27 percent, which does not appear to be significantly different than it was 30 years ago.
