Transmediastinal gunshot wounds: a prospective study.

OBJECTIVE: To evaluate admission systolic blood pressure (SBP) in the emergency center (EC) as a means by which patients with transmediastinal gunshot wounds (TM-GSWs) can be triaged to the operating room versus further diagnostic evaluation. METHODS: A prospective case series presenting concurrent data collected for 68 consecutive patients with TM-GSWs admitted to one urban trauma center over a 4.5-year period. For purposes of analysis, patients were assigned to the following groups based on SBP in the EC: group I, SBP > 100 mm Hg; group II, SBP from 60 to 100 mm Hg; group III, SBP < 60 mm Hg. RESULTS: The management and outcomes of 68 patients with a mean age of 29 years were evaluated. For patients in group I (n = 20), TM-GSW was diagnosed by findings on x-ray film for 15 patients (75%), at physical examination for 4 patients (20%), and at operation for 1 patient (5%). Indications for immediate operation were found in five patients (25%), whereas further diagnostic evaluation prompted operation for three additional patients. Only one patient developed persistent hypotension from neurogenic shock. There were two deaths from late complications. In patients in group II (n = 16), TM-GSW was diagnosed by findings on x-ray film for 9 patients (56%), at physical examination for 5 patients (31%), and at operation for 2 patients (13%). Six patients with persistent hypotension had indications for immediate operation, whereas further diagnostic evaluation in the remaining patients, who became hemodynamically normal during resuscitation, prompted operation in an additional two patients. There were two intraoperative deaths. For the patients in group III (n = 32), six patients with signs of life underwent immediate operation with one intraoperative death, seventeen patients required EC thoracotomy with 100% mortality, and nine patients were pronounced dead in the EC without an attempt at operation. CONCLUSION: The diagnosis of TM-GSW for patients in groups I and II is confirmed by finding at physical examination and on chest x-ray films in 90% of cases. In the absence of obvious bleeding, patients with TM-GSWs and SBP > 100 mm Hg may safely undergo further diagnostic evaluation. Sixty percent of such patients did not require an operation. All patients with TM-GSWs and SBP < 60 mm Hg (group III) require immediate operation. For patients with TM-GSWs, SBP from 60 to 100 mm Hg (group II), and without obvious bleeding, it is the response to resuscitation and the results of further diagnostic evaluation that determine the need for operation. Fifty percent of such patients did not require operation.

Iliac vessel injury: operative physiology related to outcome.

BACKGROUND: Fifty-three patients treated at a level I trauma center with iliac vessel injury were studied to determine if body temperature and acid-base status in the operating room predicts outcome. METHODS: Records were reviewed for demographics, mechanism of injury, body temperature, acid-base status, operative management, and outcome. Statistical methods included Student's t test, odds ratio determination, and chi-square analysis to determine statistical significance. RESULTS: Fifty-three patients (47 male, 6 female) sustained 92 iliac vascular injuries (36 arterial, 56 venous). Mortality was 34%, with 72% of deaths due to shock within 24 hours. Physiologic parameters differed significantly between survivors and nonsurvivors. Odds ratio identified six conditions; the number present predicted outcome. CONCLUSIONS: (1) There are significant differences between initial and final operating room temperature and acid-base status in survivors versus nonsurvivors with iliac vessel injury. Conditions for odds ratio can be calculated and correlated with outcome. (2) A patient with two or more conditions should be considered for an abbreviated laparotomy to allow for reversal of "physiologic failure."

The length of hospital stay after an unnecessary laparotomy for trauma: a prospective study.

OBJECTIVE: To record length of hospital stay (LOS) for patients for whom unnecessary laparotomies for trauma (no repair, no drain) were performed. The influence of complications and associated injuries on the LOS would be studied. DESIGN: Prospective case series. MATERIALS AND METHODS: Data were recorded concurrently for consecutive patients on whom unnecessary laparotomies for trauma were performed at a trauma center. MEASUREMENTS AND MAIN RESULTS: The main and secondary outcome measures were LOS and the influence of complications or associated injuries on the LOS, respectively. From 1988 until 1991, unnecessary laparotomies for trauma were performed on 254 patients. The overall mean LOS was 8.1 days (median, 6 days; range, 1-80 days), whereas the overall mean LOS for 81 patients who had no associated injuries and on whom completely negative laparotomies were performed was 4.7 days (median, 5 days; range, 2-8 days). Complications occurred in 41.3% of the patients and increased the mean LOS from 5 days (no complication) to 9 days (complication) (p = 0.0002). Associated injuries occurred in 43.7% of the patients and increased the mean LOS from 5.3 days (no associated injury) to 11.7 days (associated injury) (p = 0.0001). CONCLUSIONS: Unnecessary laparotomies for trauma resulted in a significant LOS. The presence of a complication or an associated injury significantly prolonged the LOS. Current efforts to reduce the incidence of these unnecessary procedures and minimize the occurrence of complications are worthwhile.

Unnecessary laparotomies for trauma: a prospective study of morbidity.

OBJECTIVE: Despite advances in diagnostic techniques, unnecessary laparotomies (no repairs/no drains) are still performed in trauma centers. The true risks of such procedures are unclear. Our hypothesis was that the overall incidences of complications after an unnecessary laparotomy for trauma that have been reported in the literature were significant underestimates because of flaws in study design. To test our hypothesis, a prospective study to record all perioperative complications in patients undergoing an unnecessary laparotomy for trauma was performed. DESIGN: Prospective case series. MEASUREMENTS AND MAIN RESULTS: The main outcome measures were perioperative complications. An unnecessary laparotomy was performed in 254 patients who sustained trauma. The mechanism of injury was a penetrating wound in 98% of the patients. Complications occurred in 41.3% of the patients (n = 105) and included atelectasis (15.7%), postoperative hypertension that required medical treatment (11.0%), pleural effusion (9.8%), pneumothorax (5.1%), prolonged ileus (4.3%), pneumonia (3.9%), surgical wound infection (3.2%), small bowel obstruction (2.4%), urinary infection (1.9%), and others. Complication rates for patients who did (n = 111) and did not (n = 143) have an associated injury were 61.3% and 25.9%, respectively (p = 0.0001). Complications occurred in 19.7% of 81 patients who did not have an associated injury and who did not have intraperitoneal or retroperitoneal penetration. The mortality rate for the entire series was 0.8% and was unrelated to the unnecessary laparotomies. CONCLUSIONS: Unnecessary laparotomies for trauma result in a significant morbidity when complications are recorded prospectively. Current efforts to reduce the incidence of these unnecessary procedures without increasing that of missed injuries are obviously worthwhile.

Rapid right atrial cannulation for fluid infusion during resuscitative emergency department thoracotomy.

A simple rapid technique for cannulating the right atrium during a resuscitative Emergency Department thoracotomy (EDT) for exsanguinating trauma is described. Following the thoracotomy and pericardiotomy, an ordinary Foley urinary bladder balloon catheter is inserted into the right atrial appendage for rapid, large volume normothermic blood and fluid infusion. A method for simplifying this maneuver, as well as the potential complications of over-resuscitation with myocardial distention and fluid overload, myocardial cooling, air embolism, and tricuspid valve occlusion are discussed. We recognize that this technique is radical and applicable to only a limited subset of severely injured patients, for example, victims of non-cardiac penetrating trauma who arrive at the hospital moribund or who arrest in the emergency center.

Gunshot wounds to the right thoracoabdomen: a prospective study of nonoperative management.

Dissatisified with our unnecessary laparotomy rate in patients with gunshot wounds (GSWs) to the right thoracoabdomen (RTA), a prospective study was designed to test the hypothesis that hemodynamically stable patients without peritonitis could be managed without a surgical procedure. From 1990 through 1993, 13 consecutive patients with a GSW between the right nipple, costal margin, right posterior axillary line, and anterior midline were studied. No patient had or developed more than local wound tenderness. All patients had a right hemothorax treated with a chest tube. Computed tomographic (CT) scanning of the RTA was performed within 8 hours of admission in 12 of the 13 patients, and the following injuries were noted: pulmonary contusion (12), hepatic laceration (seven), spinal cord transection (two), and a renal laceration (one). Follow-up CT scans, 3 to 14 days after injury, in six of the seven patients with hepatic wounds showed partial or complete resolution of the injury in all. In one patient, an associated renal injury was unchanged on the follow-up CT scan. Mean length of hospitalization for the 11 patients who did not have an injury to the spinal cord was 5.1 days (3-8 days). Complications included atelectasis (four), a small persistent pneumothorax (two), and pneumonia (one).(ABSTRACT TRUNCATED AT 250 WORDS)

Hot tar burns: twenty-seven hospitalized cases.

Between July 1, 1984, and December 31, 1991, 27 consecutive patients required admission to the Grady Memorial Hospital Burn Unit for care of hot tar burns. This group represented 1.4% of all admissions to this burn unit. Injuries occurred at the workplace and occurred mostly during the summer. They most commonly involved the patient slipping while carrying a bucket of hot tar. Ninety-six percent were male. The mean age was 33.7 years. Mean burn size was 13.1% total body surface area. Burn topography centered on the upper extremities and hands. Forty-one percent required a surgical procedure for their burn. Mean hospitalization time for survivors was 16.6 days. The survival rate was 92.6%. Both of the patients who died had large burns and/or preexisting medical problems. Hot tar burns occur under predictable circumstances, appear to be preventable, and have accounted for only a small fraction of all admissions to this burn unit.

Same admission colostomy closure (SACC). A new approach to rectal wounds: a prospective study.

OBJECTIVE: The purposes of this project were to study the healing of protected rectal wounds (RWs) using contrast enemas (CEs) and to establish the safety of same admission colostomy closure (SACC) in terms of colostomy closure (CC) and rectal wound-related outcomes, for selected patients with radiologically healed RWs. SUMMARY BACKGROUND DATA: Traditional treatment of RWs has included a diverting colostomy that is closed 2 or more months later during a readmission. METHODS: All patients admitted with a rectal injury were entered into this prospective study, treated with a diverting colostomy and presacral drainage, and managed according to a postoperative protocol that included a CE per anus to detect healing of the RW. Patients with no leaking on their first CE, no infection, and anal continence underwent SACC. RESULTS: From 1990 to 1993, 30 consecutive patients had rectal injuries, 90% of which resulted from gunshot wounds. The first CE was performed in 29 patients 5 to 10 days after injury. In this group, 21 patients did not and 8 did have leakage from their RWs. The proportions of RWs radiologically healed at 7 and 10 days after injury were 55.2% and 75%, respectively. Sixteen patients with a normal CE underwent SACC 9 to 19 days after injury (mean, 12.4 days). There were two fecal fistulas (2 of 7; 28.6%) after simple suture closure, none (0 of 9) after resection of the stoma with end-to-end anastomosis, and no RW-related complications after SACC. The mean hospitalization time was 17.4 days. CONCLUSIONS: The following conclusions were drawn: (1) CE confirmed healing of RWs in 75% of patients by 10 days after injury; (2) 60% of patients with RWs were candidates for SACC, and 53% were discharged with their colostomies closed; (3) SACC was performed without complications in 87.5% of patients with radiologically healed RWs; and (4) there were no RW-related complications after SACC.

Exposure of buttock burn wounds to stool in scald-abused infants and children: stool-staining of eschar and burn wound sepsis.

Between July 1, 1987 and June 30, 1990, 30 consecutive deliberately scalded children with buttock involvement were prospectively studied. Mean age was 22.5 months. Mean burn size was 18.1 per cent TBSA (total body surface area). Thirty per cent (n = 9) had diarrhea complicate their wound or autograft care. For those requiring surgery for their buttock/perineal burns, various combinations of preoperative mechanical bowel prep, oral antibiotics, postoperative occlusive intrarectal catheter, nothing-by-mouth, and rigid postoperative positioning did not protect buttock wounds and autografts from stool. Four patients had stool staining of the superficial burn wound exudate, none of whom developed burn wound sepsis or died. Four (13.3%) patients with a mean burn size of 32.3 per cent TBSA, diarrhea, and burns involving the buttock, perineum, and external genitalia died of burn wound sepsis, three of whom had deep stool staining of their burn wound and Gram-positive bacteremia. Buttock burn wounds should be examined carefully and frequently for the presence of deep stool staining, an ominous predictor of burn wound sepsis and death. Such wounds, if present, should be emergently excised.

Abusive scald burns in infants and children: a prospective study.

Between July 1, 1987 and June 30, 1990, 30 consecutive deliberately scalded children were studied prospectively. Purposes of the study were to characterize the scald-abused child and address the management problems specific to this group. Mean age was 22.5 months. Many had preburn growth retardation. Mean burn size was 18.1 per cent of the total body surface area and 37 per cent required a surgical procedure for their scald. All 30 children had burns on the buttocks. Four (13.3%) had other injuries. Eighty per cent of patients had at least one complication. In 30 per cent, diarrhea complicated nutrition support, wound, or autograft care. Four (13.3%) patients with a mean burn size of 32.3 per cent of the total body surface area, diarrhea, and burns involving the buttocks, perineum, and external genitalia died of burn wound sepsis; three of these had Gram-positive bacteremia (Staphylococcus aureus and enterococcus). Burn wounds exposed to the fecal stream (buttocks) should be examined carefully and frequently for signs of infection, particularly in those patients with diarrhea.

Gunshot wounds of the female breast: a risk for intra-abdominal injury.

We report the results of a clinical study of female patients sustaining gunshot wounds to a breast. Thirteen homicides were reviewed by the Fulton County Medical Examiner. A prospective series of patients treated by the Grady Memorial Hospital Trauma Service included eight additional cases. Ten (48%) of the combined series of 21 patients had significant intra-abdominal injury; of these, five (24%) had injuries confined to the abdomen as a result of a missile striking a breast. A wound pattern consisting of a superior breast entrance wound, an inferior breast exit wound, and an inframammary thoracoabdominal reentry wound was noted in five patients, four of whom had intra-abdominal injuries and three only intra-abdominal injuries. Careful examination for this wound pattern should alert the clinician to the possibility of intra-abdominal injury. One should anticipate a 50% incidence of intra-abdominal injury in female patients sustaining gunshot wounds to a breast.

Child abuse by scalding.

Physical abuse of children by burning is a serious crime that leaves the youngest of our children with permanent physical and emotional scars. The victims tends to be less than 2 years of age. Burn-abused children usually suffer from a spectrum of physical, psychologic, and nutritional neglect. Burn abuse is costly in terms of pain, suffering and health care. Up to 15% of acutely injured children seen in emergency departments, admitted or not, have been abused. Burns were involved in up to 22% of physical abuse cases. Up to 26% of pediatric burn admissions were the result of abuse. The most common form of burn abuse in children requiring hospitalization is the scald. Physicians who treat children and burn patients should have a knowledge of the literature and clinical factors associated with pediatric burn abuse.

The burn unit experience at Grady Memorial Hospital: 844 cases.

Between February 20, 1987 and July 13, 1990, 844 patients were admitted to the Grady Memorial Hospital Burn Unit. Mean age was 25.5 years, mean burn size 16.5% total body surface area, mean survivor hospital length of stay 15.9 days, and an overall survival 90.5%. Seventy-three percent were male. One half of the burns were less than 10% total body surface area. Almost half (48.5%) of the patients had flame burns, which accounted for 88.8% of the 80 deaths. The peak burn incidence occurred in infants and children as a result of scalds. If those with toxic epidermal necrolysis (n = 5), those without skin injury (n = 13), and those who were allowed to die (n = 16) are excluded, survival was 92.2%. Survival in 62 patients with inhalation injury (55.23%) was significantly less than that in 474 patients without inhalation injury (98.10%) (p less than 0.0001). The three variables--age, burn size, and inhalation injury--each influenced survival significantly but appeared to be dependent on each other; all three tended to increase or decrease together. Logistic regression equations to predict survival were developed.

Automobile carburetor- and radiator-related burns.

Seventy-nine persons who had sustained automobile engine carburetor- and radiator-related burns were admitted to Grady Memorial Hospital Burn Unit between June 1, 1984 and September 30, 1990. Forty patients with carburetor-priming flame burns had a mean age of 31.5 years, a mean burn size of 13.4% total body surface area, and a mean length of stay of 13.8 days. There were 37 male patients. Four patients had an inhalation injury. Twenty-two surgical procedures were performed on 13 patients. One patient was an innocent bystander, and one patient died. The clothing of 16 patients had ignited, which resulted in larger, deeper burns and in one death. Burns predominantly involved the right sides of the face, head, and torso; the right upper extremity; and the right hand. Thirty-nine patients had scald burns that were associated with uncapping a radiator. These patients had a mean age of 29.6 years, a mean burn size of 8.9% total body surface area, and a mean length of stay of 6.4 days. There were 36 male patients and three innocent bystanders. One autografting procedure was performed, and there were no deaths in this group of patients. The burn-prone person is the young adult male. The circumstances that result in such dangerous behavior are predictable, and resultant burn injuries are preventable.
