RESUMO

The idea of the preoperative anesthesia clinic as a means of examining and treating the patient so that he will arrive in the operating theater as strong and healthy as possible is well established in practice and literature.However, problems in clinic design and execution often result in high patient waiting times, decreased patient and staff satisfaction, decreased patient capacity, and high clinic costs. Although the details of clinic design, outcomes, and satisfaction have been extensively evaluated at civilian hospitals, we have not found corresponding literature addressing these issues specifically within military preoperative evaluation clinics. We find that changing to an appointment-based (versus walk-in) system and eliminating data collection step redundancies will likely result in lower wait times, higher satisfaction, lower per patient costs, and a more streamlined and resource-efficient structure.

RESUMO

INTRODUCTION: Internal hernias (IHs) occur more frequently in laparoscopic gastric bypass (LGB) surgery than in the classic open procedure. The incidence of small bowel obstruction after LGB ranges from 1.8% and 9.7%. Some have theorized that this occurs because of decreased adhesion formation. METHODS: The mesenteric irritation technique is performed after closure of the jejunojejunal mesenteric defect with a running 2-0 silk suture. A sponge is then rubbed against the closed visceral peritoneal mesentery until petechiae are visualized on the surface of the mesentery. RESULTS: In all, 338 LGBs were performed using the standard closure technique with an IH incidence of 5.3% (range 1.7% to 7.8%). When using the mesenteric irritation technique, 72 LGBs were performed with an IH rate of 1.4% (P = .13). CONCLUSIONS: Mesenteric irritation is a novel technique performed with minimal additional time and no additional equipment. This technique may prove beneficial in reducing the incidence of IHs.

RESUMO

Military orthopaedic surgeons in deployed environments along with orthopaedic surgeons working in more austere environments often find themselves without surgical equipment that they are normally accustomed to having in the operative suite. Today's U.S. Army Combat Support Hospital is appropriately focused on being prepared for modern battlefield trauma but lacks the resources for advanced sports medicine surgery to include arthroscopic equipment and implants. In this report, we describe an autograft anterior cruciate ligament reconstruction procedure using a combined mini-open extra-articular/intra-articular technique. This method could serve as a model for orthopaedic surgeons operating in more austere environments without modern sports medicine equipment and when working with the local national population who do not have access to modern health care facilities.

RESUMO

Cefazolin, a first generation cephalosporin, is a rare cause of cyclical fevers, neutropenia, and thrombocytopenia following surgical prophylaxis. We present the case of an otherwise healthy 21-year-old male who sustained a 50-cm laceration to his chest and abdomen. He received emergency department prophylaxis with cefazolin and surgical repair. Subsequently, he developed cyclical fevers, neutropenia, and thrombocytopenia, all of which resolved after antibiotic discontinuation. This is the first case report in which the perioperative administration of cefazolin following trauma resulted in significant neutropenia and thrombocytopenia. Also discussed in this report are the etiology, workup, and treatment of cefazolin-induced neutropenia.

RESUMO

BACKGROUND: Humanitarian medical care is an essential task of the deployed military health care system. The purpose of this study was to analyze referral acceptance in treating injured local national patients during Operation Enduring Freedom. METHODS: A prospective observation study of local nationals who were referred for humanitarian trauma care in Afghanistan from March through August 2009. RESULTS: Sixty-six patients were referred for evacuation for suspected non-coalition-caused injuries. The bed status at the receiving hospital was defined as green (able to accept patients), amber (nearing capacity), and red (at capacity). The only factor associated with acceptance was the accepting hospital bed status (odds ratio = 1.57%, 95% confidence interval, 1.11-2.22; P = .009). Factors not significant were age, the province of origin, the type of referring facility, a prior operation before the request, patient status/affiliation, or the mechanism of injury. CONCLUSIONS: Humanitarian medical care is directly related to the capacity for high-acuity care because bed availability is the predominate reason for acceptance or rejection.

RESUMO

BACKGROUND: The interplay of coagulopathy, acidosis, and hypothermia contributes to the death of the most seriously injured trauma patients. Because of in vitro testing and retrospective series, current recommendations advise correcting acidosis before administering recombinant factor VII (rFVIIa). METHODS: A lactic acidosis was induced in 40 kg swine, and 10 blood samples were withdrawn for testing. rFVIIa was added to the samples with and without bicarbonate correction of the pH. Conventional coagulation assays as well as rotational thromboelastography (ROTEM) were performed on these in vitro samples. Additionally, 10 acidotic and coagulopathic animals had rFVIIa administered after randomization to pH correction with bicarbonate, or remaining acidotic. Conventional coagulation and ROTEM assays were performed on the animals. RESULTS: Ex-vivo samples had a mean pH of 7.14 and International Normalized Ratio (INR) of 1.46. Addition of rFVIIa to these samples corrected the INR to 0.98 (p < 0.05). A similar effect was seen for the ROTEM extem Clotting Time (extem CT). Bicarbonate correction alone of these samples had only a modest effect on INR (1.36, p < 0.05). When administered in vivo to acidotic animals (pH, 7.15), rFVIIa lowered the INR from 1.49 to 1.01 (p < 0.05). Similar improvements in extem CT were seen. CONCLUSIONS: rFVIIa is effective at reversing the coagulopathy from lactic acidosis in a large animal model. Recommendations against its use in acidotic patients may not be valid.

RESUMO

OBJECTIVES: To examine patient perceptions and willingness to participate in resident education and to assess the effect on patient willingness and consent rates. DESIGN: Anonymous questionnaire designed to capture demographics, overall opinions of teaching programs, and willingness to consent to various scenarios of trainee participation. Descriptive and univariate analyses were performed. SETTING: Tertiary-level referral center. PATIENTS: Three hundred sixteen individuals scheduled for elective surgery. MAIN OUTCOME MEASURES: Consent rates for various scenarios. RESULTS: Of the 316 patients who completed the questionnaire, most expressed overall support of resident training: 91.2% opined that their care would be equivalent to or better than that of a private hospital, 68.3% believed they derived benefit from participation, and most consented to having an intern (85.0%) or a resident (94.0%) participate in their surgical procedure. However, when given specific, realistic scenarios involving trainee participation, major variations in the consent rate were observed. Affirmative consent rates decreased from 94.0% to 18.2% as the level of resident participation increased. Patients also were more willing to consent to the participation of a senior resident (83.1%) vs a junior resident (57.6%) or an intern (54.5%). Patients overwhelmingly opined that they should be informed of the level of resident participation and that this information could change their decision of whether to consent. CONCLUSIONS: Most patients expressed approval of teaching facilities and resident education. However, consent rates were significantly altered when more detailed information was provided and they declined with increasing levels of resident participation. Providing detailed informed consent is preferred by patients but it could adversely affect resident participation and training.

RESUMO

BACKGROUND: Prior studies have suggested a significant benefit of using deliberate hypoxemia to reperfuse ischemic tissue beds, primarily by reducing free radical injury. We sought to examine the effects of a hypoxemic reperfusion strategy in a large animal model of severe truncal ischemia. MATERIALS AND METHODS: Adult swine were subjected to 30 min of supraceliac aortic occlusion and randomized to two groups: normoxemia group (n = 9), with resuscitation at a pO2 >100 mmHg or hypoxemia group (n = 10), with initial resuscitation at a pO2 of 30-50. The two groups were compared using physiologic parameters, fluid and pressor requirements, inflammatory and oxidative markers, and histologic analysis of end-organ injury. RESULTS: All animals developed significant hemodynamic instability immediately upon reperfusion. Average mean arterial pressure at baseline rose significantly after 30 min of cross-clamp (76.8 versus 166.3 mmHg, P < 0.001). Upon reperfusion, all animals required epinephrine and fluids to maintain mean arterial pressure (MAP) greater than 60 mmHg. After stabilization, the two groups were similar in terms of central and pulmonary hemodynamics. The hypoxemic group required more mean total epinephrine (18.35 mg versus 5.28 mg, P < 0.01) with no significant difference in total fluid volume (hypoxemic 9111 ml versus 8420 mL, P = 0.730). The hypoxemic group demonstrated a more severe metabolic acidosis at all time intervals after reperfusion (pH 7.02 versus 7.16 and lactate 17 versus 13, both P < 0.01). There was no difference in malondialdehyde concentration between the two groups, but the hypoxemic group had a higher antioxidant reductive capacity at all intervals after 30 min of reperfusion (0.23 versus 0.27 uM, P = 0.03). While there was significant end-organ damage on pathologic examination of all liver and kidney specimens (mean severity of injury 1.59 and 1.76, respectively, on a scale of 1-3), there was no significant difference between the two groups. CONCLUSIONS: A hypoxemic reperfusion strategy in this large animal model failed to demonstrate any significant clinical benefit. Although there was chemical evidence of improved antioxidant capacity with hypoxemia, it was associated with more instability, metabolic and physiologic derangements, and no evidence of end-organ protection.

RESUMO

BACKGROUND: Postoperative bowel obstruction is a common condition with standard management algorithms. Bowel obstruction after bariatric surgery could require markedly different management strategies and have different outcomes. METHODS: All patients admitted for bowel obstruction were identified from the 2006 and 2007 Nationwide Inpatient Sample. Postbariatric (BAR) patients were identified and compared with the nonbariatric (NB) population for differences in demographics, operative interventions, and morbidity/mortality. RESULTS: A total of 9505 admissions for bowel obstruction in BAR patients and 54,342 in NB patients were found. The source of obstruction was most commonly the abdominal wall/internal hernias in the BAR group and adhesions in the NB group. Although nonoperative management was successful in 72% of the NB group, surgery was performed for most (62%) of the BAR group (P <.01). The BAR group was more likely to undergo laparoscopy (5% versus 2%) and abdominal wall reconstruction (38% versus 9%) and less likely to undergo ostomy (1% versus 13%) or colon resection (2% versus 9%, all P <.01). The BAR patients underwent surgery within an average of 24 hours compared with 3.3 days for the NB group (P <.01). Despite the increased rate of urgent surgery, the BAR group had a significantly shorter length of stay (4 versus 7 days), fewer complications (25% versus 44%), and lower mortality rate (.5% versus 3.5%). CONCLUSION: Bowel obstruction is a common and complex problem for patients who have undergone bariatric surgery. The management algorithms should consider the significant differences in the cause of obstruction and the need for early operative intervention in this special patient population.

RESUMO

INTRODUCTION: Trauma is a major cause of morbidity and mortality worldwide. Of patients arriving to trauma centers, patients requiring massive transfusion (MT, >or=10 units in 24 hours) are a small patient subset but are at the highest risk of mortality. Transfusion of appropriate ratios of blood products to such patients has recently been an area of interest to both the civilian and military medical community. Plasma is increasingly recognized as a critical component, though less is known about appropriate ratios of platelets. Combat casualties managed at the busiest combat hospital in Iraq provided an opportunity to examine this question. METHODS: In-patient records for 8,618 trauma casualties treated at the military hospital in Baghdad more than a 3-year interval between January 2004 and December 2006 were retrospectively reviewed and patients requiring MT (n = 694) were identified. Patients who required MT in the first 24 hours and did not receive fresh whole blood were divided into study groups defined by source of platelets: (1) patient receiving a low ratio of platelets (<1:16 apheresis platelets per stored red cell unit, aPLT:RBC) (n = 214), (2) patients receiving a medium ratio of platelets (1:16 to <1:8 aPLT:RBC) (n = 154), and (3) patients receiving a high ratio of platelets (>or=1:8 aPLT:RBC) (n = 96). The primary endpoint was survival at 24 hours and at 30 days. RESULTS: At 24 hours, patients receiving a high ratio of platelets had higher survival (95%) as compared with patients receiving a medium ratio (87%) and patients receiving the lowest ratio of platelets (64%) (log-rank p = 0.04 and p < 0.001, respectively). The survival benefit for the high and medium ratio groups remained at 30 days as compared with those receiving the lowest ratio of platelets (75% and 60% vs. 43%, p < 0.001 for both comparisons). On multivariate regression, plasma:RBC ratios and aPLT:RBC were both independently associated with improved survival at 24 hours and at 30 days. CONCLUSION: Transfusion of a ratio of >or=1:8 aPLT:RBC is associated with improved survival at 24 hours and at 30 days in combat casualties requiring a MT within 24 hours of injury. Although prospective study is needed to confirm this finding, MT protocols outside of investigational research should consider incorporation of appropriate ratios of both plasma and platelets.

RESUMO

BACKGROUND: The number of patients identified with cysts of the pancreas is increasing. The current study was undertaken to assess the natural course and malignant potential of pancreatic cysts. METHODS: From 1995 to 2008, radiology records were reviewed for the presence of cystic lesions of the pancreas (CLP) characteristics, patient demographics, and follow-up. RESULTS: Eighty-two patients met the study inclusion criteria, with a mean age at time of diagnosis of 64.4 +/- 16.7 years. Mean cyst size was 1.36 +/- 1.05 cm, with 75.6% of patients having a solitary cyst. Thirteen patients underwent surgery. Operative intervention was statistically related to symptomatic, loculated cysts with the presence of calcifications (all P <.05). Malignancy was statistically related to symptomatic (P <.05), loculated cysts (P <.01), and male gender (P <.05). CONCLUSIONS: Our data show that most pancreatic cysts found on radiographic imaging are asymptomatic, solitary, and small and can be followed safely radiographically.

RESUMO

OBJECTIVES: To describe arterial and venous injuries and their management and short-term outcomes in a wartime hospital. DESIGN: Retrospective review of patients with vascular injuries. Mechanism, location, method of repair, and outcomes were analyzed with descriptive and inferential statistics. SETTING: The 31st Combat Support Hospital, Operation Iraqi Freedom. PATIENTS: A total of 153 patients with 218 vascular injuries from January 1, 2004, to December 30, 2004. MAIN OUTCOME MEASURES: Limb salvage and mortality rates. RESULTS: The overall limb salvage rate was 80%, while all-cause mortality was 6%. Most vascular injuries were sustained by blast and fragmentation mechanisms. Not surprisingly, most vascular injuries were in lower extremity vessels (57% arterial, 50% venous), with a high predominance of superficial femoral vessel injuries. Vascular injuries to the upper extremities were associated with a higher limb salvage rate (95%) than injuries to the lower extremities (71%). Variable follow-up data for 63 (41%) patients revealed that 32 underwent further procedures outside the combat theater, 12 of which were delayed amputations. Of all arterial injuries, 36% were primarily repaired, 34% were repaired with a vein interposition graft, 29% were ligated, and 2% were repaired with a prosthetic graft. A majority of venous injuries (56%) were ligated. CONCLUSIONS: There is an acceptable early patency and limb salvage rate in combat vascular repairs. A majority of penetrating vascular injuries occur in the lower extremities. Overall, penetrating vascular trauma is often a survivable injury.

RESUMO

BACKGROUND: Morbid obesity has become a public health epidemic in the United States. With this epidemic, the demand for surgical intervention has led to rapid growth in the field of bariatric surgery. Although various procedures exist, one of the procedures offered at our institution is resectional Roux-en-Y gastric bypass with incidental cholecystectomy and appendectomy. This procedure allows for pathologic assessment of otherwise normal viscera routinely removed as a part of the gastric bypass. The purpose of this study was to determine the incidence of abnormal findings of the extirpated, gallbladder, appendix, and distal stomach after gastric bypass surgery. METHODS: We performed a retrospective review of 427 patients undergoing Roux-en-Y at a tertiary level medical center. RESULTS: Abnormal findings were divided according to the organ. In the gastric remnant, the reported pathologic findings included chronic or active gastritis in 66, fundic gland polyps in 7, intestinal metaplasia in 3, gastric ulcers in 2, gastropathy in 2, lymphoid aggregate in 1, diverticulum in 1, a developmental cyst in 1, and leiomyoma in 1. We analyzed 311 appendixes and found the following abnormalities: fibrous obliteration of the appendiceal lumen in 76, carcinoids in 2, infarcted appendicial epiploica in 2, follicular hyperplasia in 2, and subserosal endometriosis in 1. In the gallbladder the sole abnormality, other than cholelithiasis, was an adenomyoma. Other resected findings included five Meckel's diverticula, one bile duct adenoma, and one sigmoid diverticulum. CONCLUSION: The results of our study have shown that the resection of grossly normal and asymptomatic organs results in a very low prevalence of clinically significant incidental pathologic findings.

RESUMO

BACKGROUND: Historically, military surgical doctrine has mandated exploratory laparotomy for all penetrating fragmentation wounds. We hypothesized that stable patients with abdominal fragmentation injuries whose computerized tomography (CT) scans for intraperitoneal or retroperitoneal penetration disclosed nothing abnormal, can be safely observed without therapeutic laparotomy. METHODS: We retrospectively studied all hemodynamically stable patients with penetrating fragmentation wounds to the back, flank, lower chest, abdomen, and pelvis evaluated by abdominal physical examination (PE), CT, or ultrasound treated during a 6-month period at one combat support hospital. Sensitivity, specificity, and positive and negative predictive values were calculated comparing each positive test to laparotomy and each negative test to successful nonoperative management. RESULTS: One hundred forty-five patients met study criteria. Based on CT scans, 85 (59%) patients were managed nonoperatively; 60 (41%) underwent laparotomy. Forty-five of 60 (75%) of laparotomies were therapeutic. CT scan for intraperitoneal or retroperitoneal penetration that disclosed nothing abnormal was 99% predictive of successful nonoperative management. In detecting intra-abdominal injury requiring laparotomy, sensitivity for each method was 30.2% (PE), 11.7% (ultrasound), and 97.8% (CT) (p < 0.05). Specificity was 94.8% (PE), 100% (ultrasound), and 84.8% (CT). The areas under the receiver operating characteristic (ROC) curves were 0.565 (PE), 0.543 (ultrasound), and 0.929 (CT) (p < 0.0001). All patients with a positive ultrasound (n = 4) underwent therapeutic laparotomy. CONCLUSION: PE alone was unreliable in stable patients with abdominal fragmentation injuries. The clinical value of ultrasound results was limited, likely because the majority of these stable patients did not have injuries associated with the large accumulation of peritoneal fluid. CT scan safely and effectively analyzed nonoperative management of penetrating abdominal fragmentation injuries and should be the diagnostic study of choice in all stable patients without peritonitis with abdominal, flank, back, or pelvic combat fragmentation wounds.

RESUMO

BACKGROUND: Up to 9% of casualties killed in action during the Vietnam War died from exsanguination from extremity injuries. Retrospective reviews of prehospital tourniquet use in World War II and by the Israeli Defense Forces revealed improvements in extremity hemorrhage control and very few adverse limb outcomes when tourniquet times are less than 6 hours. HYPOTHESIS: We hypothesized that prehospital tourniquet use decreased hemorrhage from extremity injuries and saved lives, and was not associated with a substantial increase in adverse limb outcomes. METHODS: This was an institutional review board-approved, retrospective review of the 31st combat support hospital for 1 year during Operation Iraqi Freedom. Inclusion criteria were any patient with a traumatic amputation, major extremity vascular injury, or documented prehospital tourniquet. RESULTS: Among 3,444 total admissions, 165 patients met inclusion criteria. Sixty-seven patients had prehospital tourniquets (TK); 98 patients had severe extremity injuries but no prehospital tourniquet (No TK). Extremity Acute Injury Scores were the same (3.5 TK vs. 3.4 No TK) in both groups. Differences (p < 0.05) were noted in the numbers of patients with arm injuries (16.2% TK vs. 30.6% No TK), injuries requiring vascular reconstruction (29.9% TK vs. 52.5% No TK), traumatic amputations (41.8% TK vs. 26.3% No TK), and in those patients with adequate bleeding control on arrival (83% TK vs. 60% No TK). Secondary amputation rates (4 (6.0%) TK vs. 9 (9.1%) No TK); and mortality (3 (4.4%) TK vs. 4 (4.1%) No TK) did not differ. Tourniquet use was not deemed responsible for subsequent amputation in severely mangled extremities. Analysis revealed that four of seven deaths were potentially preventable with functional prehospital tourniquet placement. CONCLUSIONS: Prehospital tourniquet use was associated with improved hemorrhage control, particularly in the worse injured (Injury Severity Score >15) subset of patients. Fifty-seven percent of the deaths might have been prevented by earlier tourniquet use. There were no early adverse outcomes related to tourniquet use.

RESUMO

BACKGROUND: The prognostic significance of tumor location in breast cancer remains unclear. To better understand this relationship, we evaluated the Department of Defense tumor registry. METHODS: Patients with infiltrating ductal adenocarcinoma or lobular carcinoma over a 10-year period were identified and analyzed. RESULTS: Of the 13,984 tumors, 7,871 (58%) originated from the upper-outer quadrant or axillary tail, whereas the remainder were found at the nipple complex (9%), upper-inner quadrant (14%), lower-inner quadrant (9%), and lower-outer quadrant (10%). Univariate analysis of cancer-specific survival revealed a significant difference based on location of the primary breast cancer. Upper-outer quadrant lesions were associated with an independent contribution toward a survival benefit. CONCLUSIONS: Upper-outer quadrant breast cancers have a more favorable survival advantage when compared with tumors in other locations. Factors that negatively impacted survival included high-grade tumors, advanced stage, and race.

RESUMO

INTRODUCTION: Trauma training among nonsurgical physicians in the military is highly variable in amount and quality. However, all deployed military physicians, regardless of specialty, are expected to provide combat casualty care. The goal was to assess the effectiveness of an intense modular trauma refresher course for nonsurgical physicians deploying to a combat zone. METHODS: All graduating nonsurgical residents participated in this 2.5-day course, consisting of 4 modules: (1) didactic session; (2) simulation with interactive human surgical simulators; (3) case presentations and triage scenarios from Iraq/Afghanistan with associated skill stations; and (4) live tissue surgical procedure laboratory. Competency tests, surveys, and after action comments were reviewed and compared before and after course completion. RESULTS: Between May 2005 and April 2007, 60 physicians participated in the course. By specialties, there were 32 internists, 16 pediatricians, 7 general practitioners, 4 obstetricians/gynecologists, and 1 "other" nonsurgical physician represented. Precourse and postcourse tests were administered to 31 of 60 participants. The mean test scores improved from 76% to 96% upon completion of the course (p < 0.01). Additionally, self-perceived confidence levels in handling battlefield casualties from questionnaires based on Likert scale responses (1 = not confident, 5 = confident) improved from an average of 2.3 before the course to 3.9 upon completion of the course (p < 0.01). CONCLUSION: All military physicians must be prepared to manage combat casualties. This hybrid training model may be an effective method to prepare nonsurgeons to deal with battle injuries. This course significantly improved the knowledge and confidence among primary care physicians.

RESUMO

PURPOSE: Despite the evolution in the management of traumatic colorectal injuries in both civilian and military settings during the previous few decades, they continue to be a source of significant morbidity and mortality. The purpose of this study was to analyze management and clinical outcomes from a cohort of patients suffering colorectal injuries. METHODS: This was a retrospective analysis of prospectively collected data from all patients injured and treated at the 31st Combat Support Hospital during Operation Iraqi Freedom from September 2003 to December 2004. RESULTS: From the 3,442 patients treated, 175 (5.1 percent) had colorectal injuries. Patients were predominately male (95 percent), suffered penetrating injuries (96 percent), and had a mean age of 29 (range, 4-70) years. Ninety-one percent of patients had associated injuries. Initial management included primary repair (34 percent), stoma (33 percent), resection with anastomosis (19 percent), and damage control only (14 percent). By injury location, stomas were placed more frequently with rectal or sphincter injuries 65 percent (25/40) vs. other sites (right, 19 percent (8/42); transverse, 25 percent (8/32); left, 36 percent (20/55); P < 0.01). Thirteen percent of patients eventually received stomas for failure of initial in-continuity management. Patients with colorectal injuries had a significantly increased mortality rate than those without (18 percent (31/175) vs. 8 percent (269/3267); P < 0.001) but not the subset without colorectal injuries undergoing celiotomy (18 vs.14.4 percent; P = 0.41). Rectal (odds radio, 22; P = 0.03) and transverse colon (odds radio, 17; P = 0.04) injuries were independently associated with increased mortality in multivariate regression analysis. Initial placement of stoma had an independent association with lower leak rates (odds radio, 0.06; P = 0.04). CONCLUSIONS: Injury to the rectum or transverse colon is an independent predictor of mortality. The use of a diverting stoma varied by injury site and was associated with a decreased leak rate but demonstrated no impact on the incidence of sepsis or mortality.

RESUMO

BACKGROUND: Medics assigned to combat units have a notable paucity of trauma experience. Our goal was to provide intense trauma refresher training for the conventional combat medic to better prepare them for combat casualty care in the War on Terror. MATERIALS AND METHODS: Our Tactical Combat Casualty Care Course (TC3) consisted of the following five phases: (1) One and one-half-day didactic session; (2) Half-day simulation portion with interactive human surgical simulators for anatomical correlation of procedures and team building; (3) Half-day of case presentations and triage scenarios from Iraq/Afghanistan and associated skills stations; (4) Half-day live tissue lab where procedures were performed on live anesthetized animals in a controlled environment; and (5) One-day field phase where live anesthetized animals and surgical simulators were combined in a real-time, field-training event to simulate realistic combat injuries, evacuation problems, and mass casualty scenarios. Data collection consisted of surveys, pre- and posttests, and after-action comments. RESULTS: A total of 1317 personnel participated in TC3 from October 2003 through May 2005. Over the overlapping study period from December 2004 to April 2005, 327 soldiers participated in the formal five-phase course. Three hundred four (94%) students were combat medics who were preparing for combat operations in Iraq or Afghanistan. Of those completing the training, 97% indicated their confidence and ability to treat combat casualties were markedly improved. Moreover, of those 140 medics who took the course and deployed to Iraq for 1 year, 99% indicated that the principles taught in the TC3 course helped with battlefield management of injured casualties during their deployment. CONCLUSION: The hybrid training model is an effective method for training medical personnel to deal with modern battle injuries. This course increases the knowledge and confidence of combat medics deploying and fighting the Global War on Terrorism.
