RESUMO

The University of Kansas School of Medicine recently confronted challenging questions about commemorative naming. Every year, the school assigns the incoming medical students to advising groups, called academic societies. There are six societies, each bearing the name of a prominent physician from the school's history. Over the years, as students learned about the society namesakes, controversy developed over the naming of the Wahl Society. In 1938, Dr. Harry Wahl led an effort to preserve the racial segregation of the medical school. He fought hard, though unsuccessfully, to defend the established practice of barring the few Black students admitted to the school from continuing into the third and fourth year of the program and graduating. In 2017, with this history in mind, a well-organized coalition of medical students submitted a request to change the name of the Wahl Society. The society is now named the Cates Society, honoring Dr. Marjorie Cates, the first Black woman to graduate from the medical school. In this paper, we offer observations on how medical students' involvement with historical inquiry -- as well as their caution about it limits -- helped to navigate the challenging process of renaming.

RESUMO

Globally, tunas are among the most valuable fish stocks, but are also inherently difficult to monitor and assess. Samples of larvae of Western Atlantic bluefin tuna Thunnus thynnus (Linnaeus, 1758) from standardized annual surveys in the northern Gulf of Mexico provide a potential source of "offspring" for close-kin mark-recapture (CKMR) estimates of abundance. However, the spatial patchiness and highly skewed numbers of larvae per tow suggest sampled larvae may come from a small number of parents, compromising the precision of CKMR. We used high throughput genomic profiling to study sibship within and among larval tows from the 2016 standardized Gulf-wide survey compared to targeted sampling carried out in 2017. Full- and half-siblings were found within both years, with 12% of 156 samples in 2016 and 56% of 317 samples in 2017 having at least one sibling. There were also two pairs of cross cohort half-siblings. Targeted sampling increased the number of larvae collected per sampling event but resulted in a higher proportion of siblings. The combined effective sample size across both years was about 75% of the nominal size, indicating that Gulf of Mexico larval collections could be a suitable source of juveniles for CKMR in Western Atlantic bluefin tuna.

RESUMO

BACKGROUND: Pediatric head and neck burns (HNBs) require special attention due to the potential for long-term disfigurement, functional impairment, and psychosocial stigma. METHODS: We performed a retrospective review of patients <18 years old admitted to Grady Memorial Hospital with a diagnosis of HNB from 2009-2017. Demographic data, burn characteristics, management, and hospital course were analyzed. RESULTS: Of the 272 patients included, 65.4% were male with a mean age of 63.2 months. Burn mechanism was primarily secondary to scalding liquids (70.2%) or flames (23.9%). The average total body surface area involved was 10.3%, and 3.0% for the head/neck. Average length of stay was 5.2 days and overall mortality was 1.1%. Twenty-five patients (9.2%) required surgery in the acute setting, and 5 (1.8%) required secondary surgery for hypertrophic scarring or contracture. DISCUSSION: Pediatric HNBs occur most commonly in males <6 years old secondary to scalding liquids or open flames. Most patients can be managed nonoperatively without long-term sequelae.

RESUMO

Grady Memorial Hospital is a pillar of public medical and surgical care in the Southeast. The evolution of this institution, both in its physical structure as well as its approach to patient care, mirrors the cultural and social changes that have occurred in the American South. Grady Memorial Hospital opened its doors in 1892 built in the heart of Atlanta's black community. With its separate and unequal facilities and services for black and white patients, the concept of "the Gradies" was born. Virtually, every aspect of care at Grady continued to be segregated by race until the mid-20th century. In 1958, the opening of the "New Grady" further cemented this legacy of the separate "Gradies," with patients segregated by hospital wing. By the 1960s, civil rights activists brought change to Atlanta. The Atlanta Student Movement, with the support of Dr. Martin Luther King Jr., led protests outside of Grady, and a series of judicial and legislative rulings integrated medical boards and public hospitals. Eventually, the desegregation of Grady occurred with a quiet memo that belied years of struggle: on June 1, 1965, a memo from hospital superintendent Bill Pinkston read "All phases of the hospital are on a non-racial basis, effective today." The future of Grady is deeply rooted in its past, and Grady's mission is unchanged from its inception in 1892: "It will nurse the poor and rich alike and will be an asylum for black and white."

RESUMO

BACKGROUND: Frailty has demonstrated enhanced prognostic ability for elderly patient morbidity. The aim was to create a burn-specific frailty index for elderly patients and compare it to commonly used scoring systems in burn management. METHODS: From 2013 to 2017, we prospectively surveyed a randomized cohort of patients ≥65-years-old previously admitted to our burn unit. Prognostic comparisons with 6 commonly used indices and multivariate risk analyses were performed. RESULTS: Of 100 included patients, n = 32 were classified as frail. The mean patient age was 73.0 ±â€¯6.8-years with a median follow up of 20.9 months. There were 13 moralities in total, 12 occurred in the frail group including 5 in-house mortalities. Patients classified as frail had significantly more complications (p < 0.001), non-home discharges (p < 0.001), ICU admissions, and longer hospital and ICU lengths of stay (p < 0.001), decreased 1 and 3-year survival (p = 0.001). The BFI was identified as an independent predictor of mortality (p = 0.001) and course-altering diagnoses including sepsis/septic shock, ARDS/ALI, and AKI. CONCLUSIONS: The Burn Frailty Index accurately predicts morbidity and mortality in elderly frail patients suffering burn injuries.

RESUMO

Fulminant hepatic failure secondary to herpes simplex virus (HSV) is a rare complication that is associated with high mortality. Here, we describe the case of a critically ill patient with severe burns and inhalation injury who developed severe coagulopathy during her hospital stay, which was later found to be caused by HSV hepatitis. In addition, we review the current literature on HSV hepatitis. Only three prior reports document liver involvement of HSV in patients with burn. Clinical symptoms, diagnostic factors, and management of HSV hepatitis in patients with burn are presented. Because of severe immunosuppression and potentially fatal nature of this infection, clinicians should have a heightened suspicion for HSV hepatitis in burn patients with HSV mucocutaneous involvement, unexplained liver dysfunction, and severe coagulopathy, and it should prompt immediate initiation of intravenous acyclovir.

RESUMO

PURPOSE: The purpose of this project was to characterize patients with isolated head and neck burns admitted to the Grady Memorial Hospital (GMH) Burn Center (Atlanta, GA). MATERIALS AND METHODS: This was a retrospective case series of patients admitted to the GMH Burn Center with the primary diagnosis of head and neck burns from 2000 through 2015. Demographic data (gender and age) were recorded. Burn details (etiology, mechanism, percentage of burned total body surface area, depth, and associated injuries) were summarized. Patient management and hospital course were documented. Data were collected using a standardized collection form. Descriptive statistics were computed. RESULTS: There were 5,938 patients admitted to the burn unit at the GMH Burn Center during the study period. Of these, 2,547 patients had head and neck burns and 205 patients met the inclusion criteria. Most (n = 136; 66%) were male, with a mean age of 40 years. The most common burn depth was superficial partial thickness. Flame burns were the most likely mechanism related to full-thickness injury. Approximately one fourth of patients had an associated injury, such as inhalation or ocular injury. Surgical interventions consisted of tangential excision and split-thickness skin grafting, contracture release, excision of hypertrophic scars, and rotational flaps. Mean length of hospital stay for isolated head and neck burns was 4.4 days. Overall mortality was 2%. CONCLUSION: The results of this study show that superficial partial-thickness head and neck burns are more likely to occur from accidental exposure to flames in men older than 55 years. Owing to an increase in risk and mortality of inhalation injury associated with head and neck burns, airway protection and respiratory management are critical considerations of head and neck burn management.

RESUMO

BACKGROUND: Stevens-Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) result in epidermal sloughing and mucositis. There are no published guidelines for intubation and early tracheostomy in this patient population. METHODS: A retrospective chart review of 40 patients admitted from 2010 to 2015 with SJS and TEN was conducted. Descriptive statistics and significance were calculated. RESULTS: Of the 43% of patients who underwent early tracheostomy, 100% had oral involvement while the initial total body surface area (TBSA) was 70% or more in 41% of patients (P < .05). TBSA progressed 15% or more in 53% of patients with 6% having airway involvement and a neurologic diagnosis mandating intubation. Mortality was 17%. CONCLUSIONS: Indications for intubation and early tracheostomy for SJS and TEN are documented oral involvement plus one of the following: initial TBSA 70% or more; progression of TBSA involved from hospital day 1 to hospital day 3, 15% TBSA or more; underlying neurologic diagnosis preventing airway protection; and documented airway involvement on direct laryngoscopy.

RESUMO

Increasingly, patients are being evaluated for burns related to home oxygen use. Although the majority of burns are minor, referral to a burn unit regardless of depth or size is still common. The care of this population was reviewed to determine the feasibility and potential saving if such patients could be managed by nonburn-trained surgeons. Prospectively collected data on 5103 consecutive patients admitted to an urban tertiary burn center between April 1997 and September 2010 was reviewed. Data collected included age, TBSA burned, comorbidities, mode of admission, distance transported, mode of transport, number requiring surgery, length of stay, and outcome. Of 5103 admissions, 64 were for home oxygen burns. Patients had a mean age of 62.5 years and five comorbidities. They suffered a mean 4% TBSA burn, and all were mostly superficial, of partial thickness, and healed without surgery. Patients had a mean length of stay of 2 days and required one follow-up visit. Twenty-seven percent were transferred from another facility after initial care, and 28% arrived intubated. Twenty-two percent were transported by helicopter, and 61% arrived intubated. Eighty percent of ventilated patients were extubated within 8 hours of admission, and all within 24 hours. Average distance by helicopter transport was 57 miles, and cost $12,500.00. Large savings could be realized if patients cared for by local physicians were educated in basic burn care. This would be more palatable with good communication between the community hospital and burn center, with consultation on an as-needed basis.

RESUMO

BACKGROUND: Minor burns represent .96% to 1.5% of emergency department visits, yet burn center referral is common. Analysis of the Grady Memorial Hospital Burn Center examined the feasibility and savings if pediatric burns were managed locally with as-needed consultation. METHODS: Prospective data on 219 consecutive admissions to Grady Memorial Hospital Burn Center between December 2008 and September 2010 were reviewed. National and international cohorts were compared. RESULTS: Sixty-six percent of patients were male, the mean age was 6.1 years, and 92% were insured. The most common mechanism of burning was liquid scalding (40%). Seventy percent had burns over <10% of the total body surface area, and 73% of all pediatric admissions healed without surgery. Thirty-six percent were discharged within 24 hours of admission. Forty-five percent of patients transferred from other facilities were discharged within 24 hours. Fifteen percent were transported by helicopter; of those, 37% were discharged within 24 hours. Helicopter transport cost $12,500 and averaged 45 miles. CONCLUSIONS: Pediatric burns require assessment, debridement, and dressing changes. Grafting is rarely necessary. Patients are transferred because of a lack of training, and patients suffer economic burden and treatment delay. Savings could be realized were patients treated locally with select burn center referral.

RESUMO

BACKGROUND: minor burns represent .96% to 1.5% of emergency department visits, yet burn center referral is common. Analysis of the Grady Memorial Hospital Burn Center was conducted to examine the feasibility and savings if burns were managed locally with consultation as needed. METHODS: data on 776 consecutive admissions to Grady Memorial Hospital Burn Center between November 2005 and July 2007 were prospectively reviewed. National and international cohorts were compared. RESULTS: patients' mean age was 31 years, 69.8% were male, and 87% were insured. Thirty-nine percent were transfers. Seventy-six percent of transfers (51% of air transfers) and 70% of all admissions were for ≤ 10% total body surface area burns. Helicopter transport cost $12,500 and averaged 48 miles. Eighty percent of burns were hot water (scald), grease, or flame burns, and 31% required skin grafting. CONCLUSIONS: most burns require assessment, debridement, and dressing changes. Grafting is rarely necessary. Patients are transferred because of a lack of training, and patients suffer economic burden and treatment delay. Savings could be realized were patients treated locally with select burn center referral. Video consultation and mentoring can help with triage and care of minor burns. Major burns require burn center referral. International practice reinforces these results.

RESUMO

UNLABELLED:  Background. Outcomes following burn injury have improved considerably in recent years due to early excision and skin grafting. Despite a reduction in late burn complications, up to 70% of patients experience long-term pain at both the injured area and the skin-grafted scar. Current therapies do not ameliorate these symptoms for a majority of these patients. This report presents initial results of a new technique using a bilayer dermal substitute (Integra™, [Integra LifeSciences, Plainsboro, NJ]) for revision of painful scars. METHODS: This is a prospective cohort of six patients treated at Grady Memorial Hospital Burn Center (Atlanta, GA) from 2008 to 2009. Burn patients undergoing multi-modality pain therapy for chronic, painful burns were identified and consented for intervention. All patients underwent operative excision of the painful scar and placement of a bilayer dermal matrix (Integra). After 3 weeks the silicone mesh was removed, excessive granulation tissue was debrided, and a new split-thickness skin graft was placed on the wound. Prescription history and a patient questionnaire were used to collect data. RESULTS: All patients noticed improvement of symptoms post-operatively. Two patients (33%) experienced complete reduction of scar pain and three (50%) discontinued consumption of pain medications. At a mean follow up of 13 months, the average amount of narcotic-based pain medications decreased from 63.3 MED ([morphine equivalent per day], range: 30-135) before treatment to 7.5 MED (range: 0-20) postoperatively (P < 0.05). CONCLUSION: Scar excision, interval placement of a bilayer dermal matrix, and subsequent skin grafting is a new technique that can improve, and in some cases ameliorate, burn scar related pain. .

RESUMO

BACKGROUND: Early prediction of the need for massive transfusion (MT) remains difficult. We hypothesized that MT protocol (MTP) utilization would improve by identifying markers for MT (>10 units packed red blood cell [PRBC] in 24 hours) in torso gunshot wounds (GSW) requiring early transfusion and operation. METHODS: Data from all MTPs were collected prospectively from February 1, 2007, to January 31, 2009. Demographic, transfusion, anatomic, and operative data were analyzed for MT predictors. RESULTS: Of the 216 MTP activations, 78 (36%) patients sustained torso GSW requiring early transfusion and operation. Five were moribund and died before receiving MT. Of 73 early survivors, 56 received MT (76%, mean 19 units PRBC) and 17 had early bleeding control (EBC), (24%, mean 5 units PRBC). Twelve transpelvic and 13 multicavitary wounds all received MT regardless of initial hemodynamic status (mean systolic blood pressure: 96 mm Hg; range, 50-169). Of 31 MT patients with low-risk trajectories (LRT), 18 (58%) had a systolic blood pressure <90 mm Hg compared with 3 of 17 (17%) in the EBC group (p < 0.01). In these same groups, a base deficit of <-10 was present in 27 of 31 (92%) MT patients versus 4 of 17 (23%) EBC patients (p < 0.01). The presence of both markers identified 97% of patients with LRT who requiring MT and their absence would have potentially eliminated 16 of 17 EBC patients from MTP activation. CONCLUSIONS: In patients requiring early operation and transfusion after torso GSW: (1) early initiation of MTP is reasonable for transpelvic and multicavitary trajectories regardless of initial hemodynamic status as multiple or difficult to control bleeding sources are likely and (2) early initiation of MTP in patients with LRT may be guided by a combination of hypotension and acidosis, indicating massive blood loss.

RESUMO

BACKGROUND: Ligation of the significantly injured infrarenal inferior vena cava (IVC) is an accepted practice in the setting of damage control surgery. This is a report of inpatient management, outcomes, and long-term follow-up in 25 patients after IVC ligation. METHODS: The records of patients with injuries to the IVC treated in an urban level I trauma center from 1995 to 2008 were reviewed. Demographics, injury severity, and outcome data were recorded. In addition, outpatient records were reviewed and telephone interviews were conducted to assess for the presence and severity of long-term sequelae. RESULTS: One hundred patients had IVC injuries, and 25 (25%) underwent ligation. Location of injury was infrarenal in 54 patients, suprarenal in 21, retrohepatic in 15, and suprahepatic in 10. Twenty-two of 54 (41%) injuries to the infrarenal IVC and 3 of 21 (14%) injuries to the suprarenal IVC were ligated. Patients who underwent ligation had a significantly higher Injury Severity Score (ISS) (22 vs 15, P < .001), a higher transfusion requirement (26 U vs 12 U, P < .001), a longer hospital length of stay (78 days vs 26 days, P = .02), a longer intensive care unit length of stay (24 days vs 9 days, P < .001), and a higher mortality (59% vs 21%, P < .001). Ten of 13 early survivors of infrarenal IVC ligation received early below knee fasciotomy. Three other patients with normal compartment pressures were treated expectantly without development of a compartment syndrome. The 1 survivor of suprarenal ligation had below knee fasciotomies and had normal renal function by 1 month post injury, despite an initial creatinine elevation from .7 mg/dL to 3.2 mg/dL. Ten (40%) patients with IVC ligation survived to hospital discharge (9 infrarenal, 1 suprarenal), and long-term follow-up data are available in 8 patients (7 infrarenal, 1 suprarenal). At an average of 42 months (11-117 months), no patient has significant lower extremity edema or dysfunction. CONCLUSIONS: (1) Ligation of the infrarenal IVC is an acceptable damage control technique, although it remains associated with a high mortality. Ligation of the suprarenal IVC may be done, if necessary, although few survivors of this technique exist. (2) Early fasciotomy is generally required, but occasional patients may be treated expectantly, based on measurements of compartment pressures. (3) Long-term sequelae in survivors of IVC ligation for trauma are rare.

RESUMO

INTRODUCTION: Transfusion practices across the country are changing with aggressive use of plasma (fresh-frozen plasma [FFP]) and platelets during massive transfusion with current military recommendations to use component therapy at a 1:1:1 ratio of packed red blood cells to FFP to platelets. METHODS: A massive transfusion protocol (MTP) was designed to achieve a packed red blood cell:FFP:platelet ratio of 1:1:1 We prospectively gathered demographic, transfusion, and patient outcome data during the first year of the MTP and compared this with a similar cohort of injured patients (pre-MTP) receiving > or = 10 red blood cell (RBC) in the first 24 hours of hospitalization before instituting the MTP. RESULTS: One hundred sixteen MTP activations occurred. Twelve non-trauma patients and 31 who did not receive 10 RBC (15 deaths, 16 early bleeding controls) were excluded. Seventy-three MTP patients were compared with 84 patients with pre-MTP who had similar demographics and injury severity score (29 vs. 29, p = 0.99). MTP patients received an average of 23.7 RBC and 15.6 FFP transfusions compared with 22.8 RBC (p = 0.67) and 7.6 FFP (p < 0.001) transfusions in pre-MTP patients. Early crystalloid usage dropped from 9.4 L (pre-MTP) to 6.9 L (MTP) (p = 0.006). Overall patient mortality was markedly improved at 24 hours, from 36% in the pre-MTP group to 17% in the MTP group (p = 0.008) and at 30 days (34% mortality MTP group vs. 55% mortality in pre-MTP group, p = 0.04). Blunt trauma survival improvements were more marked and more sustained than victims of penetrating trauma. Early deaths from coagulopathic bleeding occurred in 4 of 13 patients in the MTP group vs. 21 of 31 patients in the pre-MTP group (p = 0.023). CONCLUSIONS: In the civilian setting, aggressive use of FFP and platelets drastically reduces 24-hour mortality and early coagulopathy in patients with trauma. Reduction in 30 day mortality was only seen after blunt trauma in this small subset.

RESUMO

BACKGROUND: In 2002, our institution published a 5-year retrospective review of 10 patients who developed secondary extremity compartment syndrome (SECS) with a mortality rate of 70%. Since then, we have aggressively screened for the development of SECS in high-risk patients. We postulate that awareness of SECS and vigilant monitoring for its development would result in earlier diagnosis and treatment and improved outcome. METHODS: Retrospective review of all patients at a level I trauma center developing SECS from 2002 to 2006. Data collected included demographics, mechanism of injury, injury complex, blood transfused prior to development of SECS, affected extremities, creatinine, creatine phosphokinase, management, and outcome. RESULTS: Seventeen of 11,468 trauma patients (.148%) developed SECS. Mean admission hematocrit was 31.7 +/- 8.9, mean admission base deficit was -13.3, mean worst base deficit was -17.8, and average Injury Severity Score was 36.3 +/- 16.6. Patients received 20.9 +/- 11.0 units of blood and 24.6 +/- 14 L of crystalloid prior to the development of SECS. Average time from admission to diagnosis of the SECS was 32.6 hours. Acute renal failure developed in 6 (35%) patients; 4 required dialysis, and 3 died. The number of affected extremities ranged from 1 to 4. Of the 46 affected extremities, 39 were salvaged and 7 required amputation. Mortality was 35.3%. CONCLUSIONS: SECS is an uncommon, but devastating complication in severely injured patients with hypotension undergoing massive transfusion, and developing systemic inflammatory response syndrome. Vigilance increases detection. While the overall mortality was reduced by half, patients requiring dialysis have a 75% mortality.

RESUMO

BACKGROUND: Ultrasound has proven to be very accurate in the diagnosis of pneumothorax in the trauma suite. It is unknown whether this accuracy is maintained over time in patients with a thoracostomy (TT) in place. METHODS: Hospitalized patients with a TT placed to treat a traumatic pneumothorax underwent serial daily bedside surgeon-performed ultrasound by 1 of 2 experienced surgeon sonographers who were unaware of concomitant X-ray findings. Results were compared with daily chest X-ray films. Data collected included size and day of placement of the chest tube, as well as the results of the serial ultrasounds and the comparative X-ray films. RESULTS: Fourteen patients (78% men, mean age 33 years) sustained traumatic pneumothorax. The causes included stab wound (9), gunshot wound (3), and rib fracture (2). They underwent 126 (median 7) ultrasound evaluations and were followed between 4 and 26 (median 7) days after injury. Of these exams, 95 had a concomitant chest X-ray film within 1 hour of the ultrasound, thus 190 hemithoraces could be analyzed. Eighty-two ultrasounds were performed for hemithoraces that had no injury or TT in place and all 82 revealed normal pleural sliding. No pneumothoraces were noted on concomitant chest X-ray films (100% accuracy). One hundred eight ultrasounds were performed for hemithoraces that had a TT in place. For the first 24 hours, accuracy remained 100%. After 24 hours, however, sensitivity of ultrasound diagnosis of pneumothorax fell to 55%, specificity fell to 70%, positive predictive value to 43%, and negative predictive value to 79%. This led to an overall accuracy rate for ultrasound examination after 24 hours of 65%. CONCLUSIONS: Ultrasound evaluation for pneumothorax is very accurate for the first 24 hours after insertion of a TT, but the accuracy, especially the positive predictive value, is not sustained over time, possibly as a result of the formation of intrapleural adhesions.

RESUMO

BACKGROUND: Recent series have reported that the mortality rate of open pelvic fractures has decreased to < 10%. These injuries are often associated with intra-abdominal visceral damage, although few series have documented the prognostic significance of this injury complex. METHODS: A retrospective review in an urban level I trauma center of all patients who sustained open pelvic fracture between 1995 and 2004. RESULTS: Forty-four patients were identified as having sustained open pelvic fracture. Average Injury Severity Score was 30, with 77% of patients having a score > or = 16. Overall mortality was 45% (n = 20): 11 early deaths and 9 late deaths at an average of 17 days. Vertical shear injuries, although rare, were universally fatal. Other risk factors for overall mortality included revised trauma score, Injury Severity Score, transfusion requirement, Faringer zones I or II injury, Gustilo grade III soft tissue injury, need for therapeutic angiography, and presence of intra-abdominal injury, the latter of which conferred 89% mortality. Risk factors for late deaths also included pelvic sepsis, which occurred in 5 patients and was fatal in 3 (60%). CONCLUSIONS: The morbidity of open pelvic fractures remains high. Associated intra-abdominal injury or active arterial bleeding requiring therapeutic angiography is associated with a grim prognosis. There is a continuing need for new therapeutic approaches to this injury complex.

RESUMO

The purpose of this study was to review recent experience with upper extremity fasciotomy. This study is a retrospective review of injured patients undergoing fasciotomy in the upper extremity at an urban trauma center. Mechanisms of injury, indications for and timing of fasciotomy, role of compartment pressures, techniques of closure, amputation rate, and patient outcomes were collected. Over a 3-year period, 201 fasciotomies were performed in the extremities of 157 injured patients, including 37 in the upper extremities of 27 patients. The mechanisms of injury were penetrating trauma in 13 patients (10 GSW, three SW), blunt or crush in 9, and burns (4 electric, 1 flame) in 5. Vascular injuries and fractures were present in 15 (56%) and 9 (33%) patients, respectively. The decision to perform a fasciotomy was a clinical one in 21 patients (75%), and only 6 patients had compartment pressures measured (range, 40-87 mm Hg; mean, 52). Upper extremity fasciotomy was performed at a first operation in 24 patients, whereas only 3 patients had a delayed fasciotomy from 6 to 48 hours after injury. Two patients died on the first hospital day, and 5 others had an amputation of an upper extremity at a mean of 8 days (range 2 to 26) after injury; however, no amputation was due to the failure to perform a timely fasciotomy. In the remaining 20 patients, closure of the fasciotomy site was performed at a mean of 9 days (range, 2 to 22) after injury, most commonly by split thickness skin grafting. Hospital stay was a mean of 20 days (range, 7-35). We conclude that 1) upper extremity fasciotomy accounts for less than 20 per cent of all fasciotomies performed; 2) a clinical decision is the most common reason for performing upper extremity fasciotomy, and only 11 per cent of patients underwent a delayed fasciotomy in this review; 3) the need for upper extremity fasciotomy is associated with a length of stay longer than expected for overall injury severity.
