A profile of female academic surgeons: training, credentials, and academic success.

The objective of this study was to determine the profile (credentials, training, and type of practice) of female academic general surgeons and factors that influenced their career choice. A survey was sent to female academic surgeons identified through general surgery residency programs and American medical schools. The women had to be Board eligible/certified by the American Board of Surgery or equivalent Board and have an academic appointment in a Department of Surgery. Data were analyzed using the SPSS program. Two hundred seventy women (age range, 32-70 years) completed the survey (98.9% response rate). Fellowships were completed by 82.3 per cent (223/270), most commonly in surgical critical care. There were 134 (50.2%, 134/367) who had two or more Board certificates, most frequently (46%, 61/134) in surgical critical care. Full-time academic appointments were held by 86.7 per cent of women, most as assistant professors, clinical track; only 12.4 per cent were tenured professors. The majority of women described their practice as "general surgery" or "general surgery with emphasis on breast." The most frequent administrative title was "Director." Only three women stated that they were "chair" of the department. The top reason for choosing surgery was "gut feeling," whereas "intellectual challenge" was the reason they pursued academic surgery. When asked "Would you do it again?", 77 per cent responded in the affirmative. We conclude that female academic surgeons are well trained, with slightly more than half having two or more Board certificates; that most female academic surgeons are clinically active assistant or associate professors whose practice is "general surgery," often with an emphasis on breast disease; that true leadership positions remain elusive for women in academic general surgery; and that 77 per cent would choose the same career again.

Trauma in pregnancy. Predicting pregnancy outcome.

A multicenter study involving three American College of Surgeons Level 1 trauma centers was undertaken to assess parameters that may predict fetal outcome. The records of 93 injured pregnant patients admitted from April 1, 1985, to March 31, 1990, were reviewed. There were three maternal deaths (3%) (mean Injury Severity Score, 43). Fourteen fetal/neonatal deaths (15%) occurred during the acute care admission period. Of these, eight were fetal deaths (two associated with maternal death), four were cases of elective abortions, and two were neonatal deaths. In general, the maternal physiologic and laboratory parameters assessed failed to accurately predict pregnancy outcome, while Injury Severity Score did differ significantly between patients whose pregnancies were viable (Injury Severity Score = 6.2) and those whose pregnancies were nonviable (Injury Severity Score = 21.6). Unique to this study were the findings that the Glasgow Coma Score also differed significantly in patients with viable (Glasgow Coma Score, 14.5) and nonviable (Glasgow Coma Score, 12.0) pregnancies, while fetal heart rate at admission to the emergency department did not. In this study, the incidence of fetal death was increased following direct uteroplacental fetal injury (100% of cases), maternal shock (67%), pelvic fracture (57%), severe head injury (56%), and hypoxia (33%). The adequacy of noninvasive maternal monitoring in assessing fetal well-being is challenged, and a discussion of diagnostic modalities for assessment for the injured gravida is set forth.

A multi-institutional study of factors associated with fetal death in injured pregnant patients.

HYPOTHESIS: Factors associated with fetal death in injured pregnant patients are related to increasing injury severity and abnormal maternal physiologic profile. DESIGN: A multi-institutional retrospective study of 13 level I and level II trauma centers from 1992 to 1996. MAIN OUTCOME MEASURE: Fetal survival. RESULTS: Of 27,715 female admissions, there were 372 injured pregnant patients (1.3%); 84% had blunt injuries and 16% had penetrating injuries. There were 14 maternal deaths (3.8%) and 35 fetal deaths (9.4%). The population suffering fetal death had higher injury severity scores (P<.001), lower Glascow Coma Scale scores (P<.001), and lower admitting maternal pH (P = .002). Most women who lost their fetus arrived in shock (P = .005) or had a fetal heart rate of less than 110 beats/min at some time during their hospitalization (P<.001). An Injury Severity Score greater than 25 was associated with a 50% incidence of fetal death. Placental abruption was the most frequent complication, occurring in 3.5% of patients and associated with 54% mortality. Cardiotrophic monitoring to detect potentially threatening fetal heart rates was performed on only 61% of pregnant women in their third trimester. Of these patients, 7 had abnormalities on cardiotrophic monitoring and underwent successful cesarean delivery. CONCLUSIONS: Fetal death was more likely with greater severity of injury. Cardiotrophic monitoring is underused in injured pregnant patients in their third trimester even after admission to major trauma centers. Increased use of cardiotrophic monitoring may decrease the mortality caused by placental abruption.

An algorithm to reduce the incidence of false-negative FAST examinations in patients at high risk for occult injury. Focused Assessment for the Sonographic Examination of the Trauma patient.

BACKGROUND: The Focused Assessment for the Sonographic Examination of the Trauma patient (FAST) sequentially surveys for the presence or absence of blood in dependent abdominal regions including the right upper quadrant, left upper quadrant, and the pelvis. But it does not readily identify intraparenchymal or retroperitoneal injuries, and a CT scan of the abdomen may be needed to reduce the incidence of missed injuries. We hypothesized that select patients who are considered high risk for occult injuries should undergo a CT scan of the abdomen when the FAST is negative so that occult injuries can be detected. STUDY DESIGN: An algorithm was prospectively tested for the evaluation of select injured patients over a 3 1/2-year period. Entrance criteria included adult patients with a blunt mechanism of trauma, a negative FAST examination, and a spine fracture (with or without cord injury), or a pelvic fracture. Trauma team members performed the FAST on patients during the Advanced Trauma Life Support secondary survey. Data recorded included the patient's mechanism and type of injury, the results of the FAST and CT scan examinations, operative or postmortem findings or both, and patient outcomes. Patients with spine injuries were grouped according to spine level and the presence or absence of neurologic deficit. The patients with pelvic fractures were grouped according to the Young and Resnick classification. RESULTS: One hundred two of 1,490 patients (6.8%) who had FAST examinations were entered into this study. Thirty-two patients (30.5%) had spine injuries, with only one false-negative ultrasound result. Seventy patients (68.6%) had pelvic fractures with 13 false-negative ultrasound results: 11 ring (9 from motor vehicle crashes, 2 from pedestrians struck), 1 acetabular, and 1 isolated pelvic fracture. Nine patients underwent nonoperative management for solid organ injuries, and 4 patients needed surgery. CONCLUSIONS: Based on these preliminary data, we conclude that patients with pelvic ring-type fractures should have CT scans of the abdomen because of the higher yield for occult injuries.

Management of casualties from the bombing at the centennial olympics.

BACKGROUND: The explosion of a bomb 75 to 100 yards away from attendees at a concert who were in the process of being evacuated from Centennial Olympic Park at approximately 1:25 AM on July 27, 1996, resulted in a multiple-casualty event involving primarily four hospitals in proximity to the blast. The purpose of this study was to review triage and care of the victims, emphasizing those with significant injuries. METHODS: Retrospective review of triage and care of injured patients. RESULTS: Ninety-six of the 111 victims of the blast were triaged in the first half hour to four hospitals within 3 miles of the bombing. Only four minor operations were performed in 61 patients evaluated at community hospitals. Ten of 35 patients evaluated at the regional trauma center underwent emergency or urgent operations, and all who were seriously injured did well. CONCLUSIONS: Although overtriage to the regional trauma center occurred, outcome was excellent in all seriously injured victims treated there.

Skin only or silo closure in the critically ill patient with an open abdomen.

BACKGROUND: The morbidity and mortality of various open abdominal techniques remains unclear. METHODS: A retrospective review was made of all trauma or general surgery patients who underwent an open abdominal closure from January 1997 to December 2000, at a large urban acute care hospital. Data are mean +/- SD. RESULTS: From 1997 to 2000, 181 patients (aged 39.8 +/- 16.5 years) had an open abdomen for abdominal infection, planned reexploration, abdominal compartment syndrome, inability to reapproximate fascia, or as part of a "damage control" procedure. Twenty-three patients went on to develop an abdominal compartment syndrome. Gastrointestinal fistulas occurred in 26 patients, and 9 patients had a dehiscence. The overall mortality was 44.7%. Of the survivors, 52% went on to fascial closure, requiring 1 to 7 additional abdominal operations. CONCLUSIONS: The morbidity of the open abdomen varies with the particular indication. Gastrointestinal fistulas are the most common acute complication and an abdominal wall hernia, the most common chronic complication.

Abdominal ultrasonography in trauma.

The use of ultrasonography for the investigation of urgent diagnostic dilemmas is by no means new. Although it has been widely used for almost 40 years, during the past two decades ultrasonography has achieved a primary role in Europe and Asia in the investigation of emergent conditions such as trauma. The use of this bedside diagnostic modality is expanding rapidly and will continue to do so. Emergency physicians have developed a fellowship program in emergency ultrasonography, have set forth a model curriculum for physician training in emergency ultrasonography, and have begun to conduct hands-on courses for academic emergency physicians. Because diagnostic ultrasonography has proven to be of value in the diagnosis and management of a variety of emergent conditions, ultrasound examination, interpretation, and clinical correlation should be immediately available around the clock in resuscitation areas. It is hoped that (1) ultrasound training will be incorporated into general surgical residency programs, (2) ultrasound curriculum and credentialing processes will be established, and (3) more surgeons will have this modality available to them as part of their diagnostic armamentarium in the evaluation of injured patients.

The history of ultrasound.

Diagnostic medical ultrasound may have a brief history, but its roots date back to the early nineteenth century. From its modest beginnings in military institutions where ultrasound was used to examine pathologic specimens, to the routine evaluation of the fetus, injured patients, and those with cerebrovascular disease, ultrasound has secured a position as a key diagnostic test both currently and in the future. Its ability to diagnose valvular and congenital heart disease has reduced the need for invasive cardiac angiography with its attendant risks. Furthermore, endoluminal, transvaginal, transrectal, and transesophageal ultrasound have expanded physicians' diagnostic armamentarium and ability to "look inside" their patients. Notwithstanding all these advancements, ultrasound research and development continue to be fostered, and the ideas of today will be the technology of tomorrow (Fig. 5).

Advances in the diagnosis and treatment of thoracic trauma.

With the exception of the use of ECG to screen patients for blunt cardiac injury, recent advances in the diagnosis of thoracic trauma involve new technology. Use of surgeon-performed pericardial and pleural ultrasound for the detection of tamponade or hemothorax, TEE or spiral CT to diagnose rupture of the thoracic aorta, and thoracoscopy to evaluate a hemothorax or the integrity of the left hemidiaphragm are all standard techniques in modern trauma centers. In terms of treatment, emergency center thoracotomy is performed more selectively and with the adjunct of staple closure for cardiac wounds. Pulmonotomy is used selectively to control deep lobar hemorrhage and to avoid the need for an emergent lobectomy. Finally, nonoperative management of an intimal tear of the thoracic aorta or delayed operative management of a full-thickness tear in the patient with multiple injuries, using beta-blocker-induced relative hypotension, is rapidly becoming the standard of care throughout the United States.

Sonographic assessment of traumatic injury. Future developments.

In all its forms and applications, sonography plays a significant role in the management of injured patients, from the emergency department to beyond hospital discharge. The use of new and existing sonographic technology will increase because sonographic imaging and measurements are generally less invasive; are inexpensive; use no ionizing radiation; and are portable, repeatable, and, in many instances, as accurate as the so-called "contemporary gold standards." The training and credentialing of physicians in sonography is in evolution and will be an increasingly important issue with more widespread use and broader applications. The future of sonography in trauma care in the next millennium is bright, and surgeons and surgical residents are encouraged to gain proficiency and learn about this new surgical frontier as it evolves.

Ultrasound as used in thoracoabdominal trauma.

Because it is unique in being portable, rapid, and noninvasive, ultrasound is particularly suited to the trauma setting. When performed by the surgeon, it offers immediate feedback that can be incorporated into the management plan for the patient. Multiple studies in this area have now documented that surgeons can perform and interpret focused ultrasound examinations. Enthusiasm for surgeons as ultrasonographers will likely increase now that the Advanced Trauma Life Support Subcommittee of the American College of Surgeons has published an algorithm that includes ultrasound for the assessment of patients with blunt truncal injuries. As a rapid, sensitive, and specific diagnostic test for the detection of pericardial tamponade, hemothorax, and hemoperitoneum, ultrasound is now an integral part of the practice at many Level I trauma centers.

The surgeon's use of ultrasound in the acute setting.

As the role of the general surgeon continues to evolve, the surgeon's use of ultrasound will surely influence practice patterns, particularly for the evaluation of patients in the acute setting. With the use of real-time imaging, the surgeon receives "instantaneous" information to augment the physical examination, narrow the differential diagnosis, or initiate an intervention. With select ultrasound examinations, the surgeon can rapidly evaluate adult and pediatric patients who present with an acute abdomen, especially those in shock. In the hands of the surgeon, this noninvasive bedside tool can more accurately assess the presence, depth, and extent of an abscess, confirm complete aspiration, or diagnose wound dehiscence before it is apparent on physical examination. Ultrasound is so accurate for the diagnosis of pyloric stenosis that it has essentially replaced the upper gastrointestinal series in most institutions. The surgeon's use of ultrasound to detect a pleural effusion has virtually replaced the lateral decubitus film. Furthermore, an ultrasound-guided thoracentesis not only facilitates the procedure but improves its safety. Many ICUs now have protocols in place to perform routine duplex surveillance of those patients who are considered at high risk for the development of thromboembolic complications. As surgeons become more facile with ultrasound, it is anticipated that other uses will develop to further enhance its value for the assessment of patients in the acute setting.

Results with abdominal vascular trauma in the modern era.

This is a report of a 10-year experience (1989-1998) with 300 consecutive patients found to have an injury to a named abdominal vessel at the time of an exploratory laparotomy for trauma. An abdominal gunshot wound was the mechanism of injury in 78 per cent of patients, and injury to more than one named abdominal vessel was present in 42 per cent. The abdominal aorta, inferior vena cava, and external iliac artery and vein were the most commonly injured vessels. When management for the five most commonly injured arteries was grouped, exsanguination before attempts at repair occurred in 11 to 15 per cent of patients and the mean survival in the remainder was 46 per cent. When management for the five most commonly injured veins was grouped, exsanguination before attempts at repair occurred in 5 per cent of patients and the mean survival in the remainder was 64 per cent. A number of administrative and medical changes in the management of patients with abdominal trauma occurred from 1992 through 1994. Despite significantly increased Injury Severity Scores for patients treated from 1993 through 1998 as compared with those treated from 1989 through 1992 survival rates for patients with injuries to the abdominal aorta and inferior vena cava were unchanged. Survival rates for injuries to the external iliac artery and vein increased significantly. The local changes in management should be considered for prospective studies in other urban trauma centers.

Penetrating cardiac trauma at an urban trauma center: a 22-year perspective.

This is a report of a 22-year experience with penetrating cardiac trauma at a single urban Level I trauma center. We conducted a retrospective chart review supplemented by computerized patient log. Comparisons of mortality between Period 1 (1975-1985; 113 patients) and Period 2 (1986-1996; 79 patients) were by chi2 or Fisher's exact tests. Statistical significance was defined as P < or = 0.05. From 1975 to 1996, 192 patients (mean age, 32 years; 88% male) with penetrating cardiac stab wounds (68%) or gunshot wounds (32%) were treated. The most common initial clinical presentation was cardiac tamponade, and most patients (54%) were hypotensive (systolic blood pressure 30-90 mm Hg). The most common initial intervention in the emergency center was tube thoracostomy. The use of pericardiocentesis as a diagnostic and therapeutic modality in the emergency center virtually disappeared in Period 2, as compared with Period 1. Since 1994, surgeon-performed cardiac ultrasound has been performed and has correctly diagnosed hemopericardium in 12 patients (100% survival). The overall mortality for all patients during the 22-year study interval was 25 per cent and was not significantly different between Period 1 (27%) and Period 2 (22%). The mortality associated with gunshot wounds was increased compared with that of stab wounds. Similarly, mortality for patients who arrested in the emergency center was increased compared with those patients who did not arrest. We conclude: 1) cardiac tamponade is the most common presentation in patients with cardiac wounds; 2) pericardiocentesis in the emergency center has essentially disappeared; 3) surgeon-performed ultrasound of the pericardium should improve survival of future patients who are normotensive or mildly hypotensive; 4) over the last 11 years, there has been a substantial decrease in mortality in patients with stab wounds and a statistically significant decrease in arrested patients; and 5) overall mortality for penetrating cardiac trauma has not changed during the 22-year interval.

Validation of surgeon-performed emergency abdominal ultrasonography in pediatric trauma patients.

BACKGROUND/PURPOSE: The focused assessment for the sonographic evaluation of trauma patients (FAST) in adults is effective in detecting intraperitoneal and intrapericardial fluid and can be performed quickly by surgeons in the emergency department (ED). The authors sought to validate the accuracy of FAST performed by surgeons during ED resuscitation of pediatric trauma patients. METHODS: Patients were assigned to one of three groups based on standard clinical criteria: immediate surgery, abdominal computed tomography (CT), or observation alone. FAST was then performed in the ED by a surgery resident (postgraduate year 3 or higher) or an attending trauma surgeon. Four views were used to assess the possible presence of fluid in the pericardial, subphrenic, subhepatic, and pelvic spaces. Time needed to conduct FAST was noted. Presence of peritoneal or pericardial fluid by FAST was compared with that determined by CT or surgery. Sensitivity, specificity, and predictive values were calculated. For those who did not undergo CT or surgery, FAST findings were compared with the clinical course. RESULTS: Technically adequate studies could be performed on 192 of 196 eligible children. Their ages ranged from 3 months to 14 years (mean, 6.9 years); 119 were boys (62%), and 188 (98%) had sustained a blunt injury. FAST was performed in a mean time of 3.9 minutes (range, 1-17 minutes). All FAST examinations were reviewed by our senior surgeon-sonographer (GSR). Interrater agreement between the performing and reviewing surgeon-sonographer was 100%. Sixty (31%) patients underwent either abdominal CT (n = 56; mean Injury Severity Score (ISS), 9.6) or immediate operation (n = 4; mean ISS, 18.8). Of the 10 patients with verified presence of intraperitoneal fluid, eight had positive and two had false-negative FAST examination results. Of the 50 patients with verified absence of intraperitoneal fluid, none had a positive FAST (ie, no false-positives); sensitivity was 80%; specificity, 100%; predictive value positive, 100%; predictive value negative, 96%. None of the 132 patients followed up clinically without CT or surgery (mean ISS, 4.5) had fluid documented by FAST, and all did well. CONCLUSIONS: The focused assessment for the sonographic evaluation of pediatric blunt trauma patients performed by surgical residents and attendings in the ED rapidly and accurately predicted the presence or absence of intraperitoneal fluid. The FAST is a potentially valuable tool to rapidly prioritize the need for laparotomy in the child with multiple injuries and extraabdominal sources of bleeding.

Surgeon-performed ultrasound for the assessment of abdominal injuries.

The use of ultrasound for the investigation of urgent diagnostic dilemmas is by no means new. Although it has been widely used for almost 40 years, during the past two decades ultrasound has achieved a primary role in the investigation of emergent conditions, notably in the trauma setting. This is further underscored by the American College of Surgeons (ACS) training initiatives. In addition to the basic ultrasound course sponsored by the ACS at the Clinical Congress meetings, the ACS will offer a specialty module course, "Ultrasound in the Acute Setting," that covers ultrasound as used in trauma, critical care, and acute general surgical problems. This initiative underscores the surgeons' interest in having ultrasound as an integral part of their trauma practice. Having the ability to perform and interpret the ultrasound examination gives the surgeon the advantage of obtaining immediate information about the patient. Considering the pace of the trauma setting, ultrasound is an ideal modality for assessment of these patients. It should be the initial diagnostic test for the evaluation of patients with precordial wounds and blunt truncal injuries because it is rapid and accurate, and it augments the surgeon's diagnostic capabilities.

Surgeon-performed ultrasound imaging in acute surgical disorders.

As the role of the general surgeon continues to evolve, the surgeon's use of ultrasound imaging will surely influence practice patterns, particularly for the evaluation of patients in the acute setting. With the use of real-time imaging, the surgeon receives "instantaneous" information to augment the physical examination, to narrow the differential diagnosis, or to initiate an intervention. With select ultrasound examinations, the surgeon can rapidly evaluate adult and pediatric patients with an acute abdomen, especially those patients who are hypotensive. In the hands of the surgeon, this noninvasive, bedside tool can assess more accurately the presence, depth, and extent of an abscess, confirm complete aspiration, or diagnose wound dehiscence before it is apparent on physical examination. Ultrasound imaging is so accurate for the diagnosis of pyloric stenosis that it has essentially replaced the upper gastrointestinal series in most institutions. The surgeon's use of ultrasound imaging to detect a pleural effusion has virtually supplanted the lateral decubitus radiograph. Furthermore, an ultrasound-guided thoracentesis not only facilitates the procedure but improves its safety. As surgeons become more facile with ultrasound imaging, it is anticipated that other uses will develop to further enhance its value for the assessment of patients in the acute setting.
