Comparison of treatment and outcomes in blunt thoracic aortic injury based on different vascular surgery guidelines.

OBJECTIVE: Society for Vascular Surgery (SVS) recommendations for managing intimal (grade 1) blunt thoracic aortic injuries (BTAIs) include observation and medical management. University of Washington (UW) revised criteria suggest that intimal injuries with ≥1 cm flap should be upgraded to a moderate injury and treatment be considered. We sought to evaluate and compare SVS and UW criteria for BTAI and determine how discordance in grading affected treatment and outcome. METHODS: We reviewed all patients admitted with BTAI from January 1, 2011, to March 31, 2022. Data included injury grading, demographics, and concomitant traumatic injuries. Images were reviewed to categorize the injury with both grading systems. Treatment and outcomes were analyzed for concordant and discordant groups. RESULTS: Our cohort comprised 208 patients after excluding four who died upon arrival. The mean age was 45 ± 19 years, 69% were men, and the median injury severity score was 34 (interquartile range, 26-45). Strong agreement was observed between the grading systems (kappa = 0.88). All patients with concordant grade 1 injuries (n = 54) were observed. SVS grade 1/2 BTAIs were reclassified in 12 of 71 patients (16.9%). Two (28.6%) SVS grade 2 injuries were graded lower with the UW criteria; neither patient required immediate or delayed repair. Ten (15.6%) SVS grade 1 BTAIs were graded higher with UW criteria. Of these, six underwent repair (one for preoperative embolization), and four were observed without sequalae. Overall mortality was 7.7% with no difference for concordant or discordant grades (7.7% vs 8.3%; P = .99). No aneurysm-related mortalities were observed. Follow-up imaging was available for 94 survivors (49.0%) at a median of 193 days (interquartile range, 42-522 days). Two patients unrepaired at the index hospitalization (SVS grade 3/UW grade 2) underwent successful delayed repair. No patient observed for a minimal injury had BTAI progression or required treatment. CONCLUSIONS: The UW grading system may upgrade or downgrade SVS grade 1 or 2 BTAI for as many as one in six injuries. Upgraded injuries should prompt consideration of repair if there is evidence of flap progression or thromboembolic complications. Downgraded injuries suggest that treatment may not be necessary; clinical expertise is key to determine optimal management in these patients.

Multidisciplinary Management of Blunt Renal Artery Injury with Endovascular Therapy in the Setting of Polytrauma: A Case Report and Review of the Literature.

BACKGROUND: Injury to the renal artery is a rare but serious concern in patients suffering blunt trauma. Complications of renovascular injury include prolonged hospitalization, kidney loss, and death. There remains considerable controversy regarding the optimal treatment of blunt renal artery injury. METHODS: We describe the management of a 39-year-old woman following blunt polytrauma who underwent a multidisciplinary collaborative procedure with open splenectomy and endovascular repair of an occluded renal artery. A literature review of the past 25 years follows including all publications describing endovascular treatment for blunt renal artery injury. RESULTS: The literature search identified 27 patients with blunt renal artery injury treated by endovascular means. All patients were treated with angioplasty and stenting; none were treated with angioplasty alone. One patient (4%) required nephrectomy for hypertension and 89% of patients were reported to be in good condition at their last contact with the healthcare system. CONCLUSIONS: The optimal treatment of blunt injury to the renal artery is unknown, but endovascular therapy is a feasible and reasonable choice. Further study is warranted to delineate the appropriate role for endovascular treatment as a component of a multidisciplinary approach to the care of trauma patients with blunt renal artery injury.

Guidance Document for the Prehospital Use of Tranexamic Acid in Injured Patients.

Tranexamic acid (TXA) is being administered already in many prehospital air and ground systems. Insufficient evidence exists to support or refute the prehospital administration of TXA, and results are pending from several prehospital studies currently in progress. We have created this document to aid agencies and systems in best practices for TXA administration based on currently available best evidence. This document has been endorsed by the American College of Surgeons-Committee on Trauma, the American College of Emergency Physicians, and the National Association of EMS Physicians.

Mass casualty disasters: who should run the show?

BACKGROUND: A clear command structure ensures quality patient care despite overwhelmed resources during a mass casualty incident (MCI). The American College of Surgeons has stated that surgeons should strive to occupy these leadership roles. OBJECTIVE: We sought to identify whether surgeons, as compared to emergency physicians, are sufficiently prepared to assume command in the event of a mass disaster. METHODS: We surveyed hospital-affiliated surgeons and emergency physicians to assess their knowledge of MCI response principles and to gauge opinions regarding who should be in charge during a disaster. RESULTS: One hundred and forty-nine (58%) surveys were completed, 78 by surgeons and 71 by emergency physicians. Both groups demonstrated a critical lack of knowledge regarding fundamental principles and key logistical components of preparedness and MCI response. Surgeons as a group were even less prepared than emergency physicians. Of those surgeons who had reviewed their hospital's disaster plan, half (50%) still did not know where to report for an MCI activation. Nonetheless, both groups believed they had sufficient training and both asserted they ought to occupy command positions during a disaster scenario. CONCLUSIONS: Errors in disaster triage have been known to increase mortality as well as the monetary cost of disaster response. Funding exists to improve hospital preparedness, but surgeons are lagging behind emergency physicians in taking advantage of these opportunities. Overall, it is imperative that physicians improve their understanding of the MCI response protocols they will be tasked to implement should disaster strike.

Tranexamic Acid and Pulmonary Complications: A Secondary Analysis of an EAST Multicenter Trial.

BACKGROUND: Anti-inflammatory effects of tranexamic acid (TXA) in reducing trauma endotheliopathy may protect from acute lung injury. Clinical data showing this benefit in trauma patients is lacking. We hypothesized that TXA administration mitigates pulmonary complications in penetrating trauma patients. MATERIALS AND METHODS: This is a post-hoc analysis of a multicenter, prospective, observational study of adults (18+ years) with penetrating torso and/or proximal extremity injury presenting at 25 urban trauma centers. Tranexamic acid administration in the prehospital setting or within three hours of admission was examined. Participants were propensity matched to compare similarly injured patients. The primary outcome was development of pulmonary complication (ARDS and/or pneumonia). RESULTS: A total of 2382 patients were included, and 206 (8.6%) received TXA. Of the 206, 93 (45%) received TXA prehospital and 113 (55%) received it within three hours of hospital admission. Age, sex, and incidence of massive transfusion did not differ. The TXA group was more severely injured, more frequently presented in shock (SBP < 90 mmHg), developed more pulmonary complications, and had lower survival (P < 0.01 for all). After propensity matching, 410 patients remained (205 in each cohort) with no difference in age, sex, or rate of shock. On logistic regression, increased emergency department heart rate was associated with pulmonary complications. Tranexamic acid was not associated with different rate of pulmonary complications or survival on logistic regression. Survival was not different between the groups on logistic regression or propensity score-matched analysis. CONCLUSIONS: Tranexamic acid administration is not protective against pulmonary complications in penetrating trauma patients.

Prospective evaluation of early follow-up chest radiography after penetrating thoracic injury.

BACKGROUND: In asymptomatic patients with penetrating thoracic trauma and a normal initial chest x-ray, successive prospective trials have decreased the minimum observation period required for exclusion of significant injury from 6 to 3 h. Despite the quality of these studies, this interval remains arbitrary and the true requisite observation time for safe discharge remains unknown. The current study evaluates the ability of "early" repeat chest x-ray, at intervals approaching 1 h, to exclude clinically significant injury. METHODS: Eighty-eight, asymptomatic patients with penetrating chest trauma and normal initial chest radiographs were prospectively enrolled in this study. All patients received an "early" follow-up chest x-ray, at a median interval of 1 h and 34 min (interquartile range: 1 h 35 min to 2 h 22 min), and a second repeat x-ray at a "delayed" interval no earlier than 3 h postadmission. Radiographic abnormalities in clinically stable patients were followed with serial examination and repeat imaging for a minimum of 6 h. All patients received both "early" and "delayed" repeat CXRs with no patient discharged before full assessment. RESULTS: One of the 88 patients with initially normal chest x-ray underwent tube thoracostomy at the discretion of the attending surgeon before any repeat imaging. Of the remaining patients, 4 of 87 (4.6 %) demonstrated radiographic abnormalities on "early" repeat imaging. Two patients had pneumothoraces, successfully managed without intervention; the remaining two demonstrated evidence of hemothorax, subsequently undergoing tube thoracostomy. Two more patients (2.3 %) developed pneumothoraces on "delayed" imaging, both successfully observed without intervention. CONCLUSIONS: In asymptomatic patients with penetrating thoracic trauma and normal initial chest radiographs, "early" repeat chest x-ray, at intervals approaching 1 h, appears sufficient to exclude clinically significant pathology and to allow safe patient discharge.

Disaster planning for a surgical surge: when mass trauma threatens to overwhelm your operating rooms.

Mass casualty events particularly those requiring multiple simultaneous operating rooms are of increasing concern. Existing literature predominantly focuses on mass casualty care in the emergency department. Hospital disaster plans should include a component focused on preparing for multiple simultaneous operations. When developing this plan, representatives from all segments of the perioperative team should be included. The plan needs to address activation, communication, physical space, staffing, equipment, blood and medications, disposition offloading, special populations, and rehearsal.

Are trauma surgeons prepared? A survey of trauma surgeons' disaster preparedness before and during the COVID-19 pandemic.

Objective: US trauma centers (TCs) must remain prepared for mass casualty incidents (MCIs). However, trauma surgeons may lack formal MCI training. The recent COVID-19 pandemic drove multiple patient surges, overloaded Emergency Medical Services (EMS) agencies, and stressed TCs. This survey assessed trauma surgeons' MCI training, experience, and system and personal preparedness before the pandemic compared with the pandemic's third year. Methods: Survey invitations were emailed to all 1544 members of the American Association for the Surgery of Trauma in 2019, and then resent in 2022 to 1575 members with additional questions regarding the pandemic. Questions assessed practice type, TC characteristics, training, experience, beliefs about personal and hospital preparedness, likelihood of MCI scenarios, interventions desired from membership organizations, and pandemic experiences. Results: The response rate was 16.7% in 2019 and 12% in 2022. In 2022, surgeons felt better prepared than their hospitals for pandemic care, mass shootings, and active shooters, but remained feeling less well prepared for cyberattack and hazardous material events, compared with 2019. Only 35% of the respondents had unintentional MCI response experience in 2019 or 2022, and even fewer had experience with intentional MCI. 78% had completed a Stop the Bleed (STB) course and 63% own an STB kit. 57% had engaged in family preparedness activities; less than 40% had a family action plan if they could not come home during an MCI. 100% of the respondents witnessed pandemic-related adverse events, including colleague and coworker illness, patient surges, and resource limitations, and 17% faced colleague or coworker death. Conclusions: Trauma surgeons thought that they became better at pandemic care and rated themselves as better prepared than their hospitals for MCI care, which is an opportunity for them to take greater leadership roles. Opportunities remain to improve surgeons' family and personal MCI preparedness. Surgeons' most desired professional organization interventions include advocacy, national standards for TC preparedness, and online training. Level of evidence: VII, survey of expert opinion.

Blunt pancreatic trauma: A Western Trauma Association critical decisions algorithm.

BACKGROUND: The Western Trauma Association (WTA) has undertaken publication of best practice clinical practice guidelines on multiple trauma topics. These guidelines are based on scientific evidence, case reports, and best practices per expert opinion. Some of the topics covered by this consensus group do not have the ability to have randomized controlled studies completed because of complexity, ethical issues, financial considerations, or scarcity of experience and cases. Blunt pancreatic trauma falls under one of these clinically complex and rare scenarios. This algorithm is the result of an extensive literature review and input from the WTA membership and WTA Algorithm Committee members. METHODS: Multiple evidence-based guideline reviews, case reports, and expert opinion were compiled and reviewed. RESULTS: The algorithm is attached with detailed explanation of each step, supported by data if available. CONCLUSION: Blunt pancreatic trauma is rare and presents many treatment challenges.

Prehospital end-tidal carbon dioxide is predictive of death and massive transfusion in injured patients: An Eastern Association for Surgery of Trauma multicenter trial.

BACKGROUND: Prehospital identification of the injured patient likely to require emergent care remains a challenge. End-tidal carbon dioxide (ETCO2) has been used in the prehospital setting to monitor respiratory physiology and confirmation of endotracheal tube placement. Low levels of ETCO2 have been demonstrated to correlate with injury severity and mortality in a number of in-hospital studies. We hypothesized that prehospital ETCO2 values would be predictive of mortality and need for massive transfusion (MT) in intubated patients. METHODS: This was a retrospective multicenter trial with 24 participating centers. Prehospital, emergency department, and hospital values were collected. Receiver operating characteristic curves were created and compared. Massive transfusion defined as >10 U of blood in 6 hours or death in 6 hours with at least 1 U of blood transfused. RESULTS: A total of 1,324 patients were enrolled. ETCO2 (area under the receiver operating characteristic curve [AUROC], 0.67; confidence interval [CI], 0.63-0.71) was better in predicting mortality than shock index (SI) (AUROC, 0.55; CI, 0.50-0.60) and systolic blood pressure (SBP) (AUROC, 0.58; CI, 0.53-0.62) (p < 0.0005). Prehospital lowest ETCO2 (AUROC, 0.69; CI, 0.64-0.75), SBP (AUROC, 0.75; CI, 0.70-0.81), and SI (AUROC, 0.74; CI, 0.68-0.79) were all predictive of MT. Analysis of patients with normotension demonstrated lowest prehospital ETCO2 (AUROC, 0.66; CI, 0.61-0.71), which was more predictive of mortality than SBP (AUROC, 0.52; CI, 0.47-0.58) or SI (AUROC, 0.56; CI, 0.50-0.62) (p < 0.001). Lowest prehospital ETCO2 (AUROC, 0.75; CI, 0.65-0.84), SBP (AUROC, 0.63; CI, 0.54-0.74), and SI (AUROC, 0.64; CI, 0.54-0.75) were predictive of MT in normotensive patients. ETCO2 cutoff for MT was 26 mm Hg. The positive predictive value was 16.1%, and negative predictive value was high at 98.1%. CONCLUSION: Prehospital ETCO2 is predictive of mortality and MT. ETCO2 outperformed traditional measures such as SBP and SI in the prediction of mortality. ETCO2 may outperform traditional measures in predicting need for transfusion in occult shock. LEVEL OF EVIDENCE: Diagnostic test, level III.

An analysis of police transport in an Eastern Association for the Surgery of Trauma multicenter trial examining prehospital procedures in penetrating trauma patients.

BACKGROUND: Police transport (PT) of penetrating trauma patients in urban locations has become routine in certain metropolitan areas; however, whether it results in improved outcomes over prehospital Advanced life support (ALS) transport has not been determined in a multicenter study. We hypothesized that PT would not result in improved outcomes. METHODS: This was a multicenter, prospective, observational study of adults (18+ years) with penetrating trauma to the torso and/or proximal extremity presenting at 25 urban trauma centers. Police transport and ALS patients were allocated via nearest neighbor, propensity matching. Transport mode also examined by Cox regression. RESULTS: Of 1,618 total patients, 294 (18.2%) had PT and 1,324 (81.8%) were by ALS. After matching, 588 (294/cohort) remained. The patients were primarily Black (n = 497, 84.5%), males (n = 525, 89.3%, injured by gunshot wound (n = 494, 84.0%) with 34.5% (n = 203) having Injury Severity Score of 16 or higher. Overall mortality by propensity matching was not different between cohorts (15.6% ALS vs. 15.0% PT, p = 0.82). In severely injured patients (Injury Severity Score ≥16), mortality did not differ between PT and ALS transport (38.8% vs. 36.0%, respectively; p = 0.68). Cox regression analysis controlled for relevant factors revealed no association with a mortality benefit in patients transported by ALS. CONCLUSION: Police transport of penetrating trauma patients in urban locations results in similar outcomes compared with ALS. Immediate transport to definitive trauma care should be emphasized in this patient population. LEVEL OF EVIDENCE: Prognostic and Epidemiologic; Level III.

Optimal positioning for emergent needle thoracostomy: a cadaver-based study.

BACKGROUND: Needle thoracostomy is an emergent procedure designed to relieve tension pneumothorax. High failure rates because of the needle not penetrating into the thoracic cavity have been reported. Advanced Trauma Life Support guidelines recommend placement in the second intercostal space, midclavicular line using a 5-cm needle. The purpose of this study was to evaluate placement in the fifth intercostal space, midaxillary line, where tube thoracostomy is routinely performed. We hypothesized that this would result in a higher successful placement rate. METHODS: Twenty randomly selected unpreserved adult cadavers were evaluated. A standard 14-gauge 5-cm needle was placed in both the fifth intercostal space at the midaxillary line and the traditional second intercostal space at the midclavicular line in both the right and left chest walls. The needles were secured and thoracotomy was then performed to assess penetration into the pleural cavity. The right and left sides were analyzed separately acting as their own controls for a total of 80 needles inserted into 20 cadavers. The thickness of the chest wall at the site of penetration was then measured for each entry position. RESULTS: A total of 14 male and 6 female cadavers were studied. Overall, 100% (40 of 40) of needles placed in the fifth intercostal space and 57.5% (23 of 40) of the needles placed in the second intercostal space entered the chest cavity (p < 0.001); right chest: 100% versus 60.0% (p = 0.003) and left chest: 100% versus 55.0% (p = 0.001). Overall, the thickness of the chest wall was 3.5 cm ± 0.9 cm at the fifth intercostal space and 4.5 cm ± 1.1 cm at the second intercostal space (p < 0.001). Both right and left chest wall thicknesses were similar (right, 3.6 cm ± 1.0 cm vs. 4.5 cm ± 1.1 cm, p = 0.007; left, 3.5 ± 0.9 cm vs. 4.4 cm ± 1.1 cm, p = 0.008). CONCLUSIONS: In a cadaveric model, needle thoracostomy was successfully placed in 100% of attempts at the fifth intercostal space but in only 58% at the traditional second intercostal position. On average, the chest wall was 1 cm thinner at this position and may improve successful needle placement. Live patient validation of these results is warranted.

An Eastern Association for the Surgery of Trauma multicenter trial examining prehospital procedures in penetrating trauma patients.

BACKGROUND: Prehospital procedures (PHP) by emergency medical services (EMS) are performed regularly in penetrating trauma patients despite previous studies demonstrating no benefit. We sought to examine the influence of PHPs on outcomes in penetrating trauma patients in urban locations where transport to trauma center is not prolonged. We hypothesized that patients without PHPs would have better outcomes than those undergoing PHP. METHODS: This was an Eastern Association for the Surgery of Trauma-sponsored, multicenter, prospective, observational trial of adults (18+ years) with penetrating trauma to the torso and/or proximal extremity presenting at 25 urban trauma centers. The impact of PHPs and transport mechanism on in-hospital mortality were examined. RESULTS: Of 2,284 patients included, 1,386 (60.7%) underwent PHP. The patients were primarily Black (n = 1,527, 66.9%) males (n = 1,986, 87.5%) injured by gunshot wound (n = 1,510, 66.0%) with 34.1% (n = 726) having New Injury Severity Score of ≥16. A total of 1,427 patients (62.5%) were transported by Advanced Life Support EMS, 17.2% (n = 392) by private vehicle, 13.7% (n = 312) by police, and 6.7% (n = 153) by Basic Life Support EMS. Of the PHP patients, 69.1% received PHP on scene, 59.9% received PHP in route, and 29.0% received PHP both on scene and in route. Initial scene vitals differed between groups, but initial emergency department vitals did not. Receipt of ≥1 PHP increased mortality odds (odds ratio [OR], 1.36; 95% confidence interval [CI], 1.01-1.83; p = 0.04). Logistic regression showed increased mortality with each PHP, whether on scene or during transport. Subset analysis of specific PHP revealed that intubation (OR, 10.76; 95% CI, 4.02-28.78; p < 0.001), C-spine immobilization (OR, 5.80; 95% CI, 1.85-18.26; p < 0.01), and pleural decompression (OR, 3.70; 95% CI, 1.33-10.28; p = 0.01) had the highest odds of mortality after adjusting for multiple variables. CONCLUSION: Prehospital procedures in penetrating trauma patients impart no survival advantage and may be harmful in urban settings, even when performed during transport. Therefore, PHP should be forgone in lieu of immediate transport to improve patient outcomes. LEVEL OF EVIDENCE: Prognostic, level III.

End-tidal carbon dioxide underestimates plasma carbon dioxide during emergent trauma laparotomy leading to hypoventilation and misguided resuscitation: A Western Trauma Association Multicenter Study.

BACKGROUND: End-tidal carbon dioxide (ETCO2) is routinely used during elective surgery to monitor ventilation. The role of ETCO2 monitoring in emergent trauma operations is poorly understood. We hypothesized that ETCO2 values underestimate plasma carbon dioxide (pCO2) values during resuscitation for hemorrhagic shock. METHODS: Multicenter trial was performed analyzing the correlation between ETCO2 and pCO2 levels. RESULTS: Two hundred fifty-six patients resulted in 587 matched pairs of ETCO2 and pCO2. Correlation between these two values was very poor with an R of 0.04. 40.2% of patients presented to the operating room acidotic and hypercarbic with a pH less than 7.30 and a pCO2 greater than 45 mm Hg. Correlation was worse in patients that were either acidotic or hypercarbic. Forty-five percent of patients have a difference greater than 10 mm Hg between ETCO2 and pCO2. A pH less than 7.30 was predictive of an ETCO2 to pCO2 difference greater than 10 mm Hg. A difference greater than 10 mm Hg was predictive of mortality independent of confounders. CONCLUSION: Nearly one half (45%) of patients were found to have an ETCO2 level greater than 10 mm Hg discordant from their PCO2 level. Reliance on the discordant values may have contributed to the 40% of patients in the operating room that were both acidotic and hypercarbic. Early blood gas analysis is warranted, and a lower early goal of ETCO2 should be considered. LEVEL OF EVIDENCE: Therapeutic, level IV.

Evaluation and management of abdominal stab wounds: A Western Trauma Association critical decisions algorithm.

This is a recommended management algorithm from the Western Trauma Association addressing the management of adult patients with abdominal stab wounds. Because there is a paucity of published prospective randomized clinical trials that have generated Class I data, these recommendations are based primarily on published observational studies and expert opinion of Western Trauma Association members. The algorithm and accompanying comments represent a safe and sensible approach that can be followed at most trauma centers. We recognize that there will be patient, personnel, institutional, and situational factors that may warrant or require deviation from the recommended algorithm. We encourage institutions to use this as a guideline to develop their own local protocols.

Occult pneumothorax in trauma patients: development of an objective scoring system.

BACKGROUND: The incidence of occult pneumothorax (OPTX) has dramatically increased since the widespread use of computed tomography (CT) scanning. The OPTX is defined as a pneumothorax not identified on plain chest X-ray but detected by CT scan. The overall reported incidence is about 5% to 8% of all trauma patients. We conducted a 5-year review of our OPTX incidence and asked if an objective score could be developed to better quantify the OPTX. This in turn may guide the practitioner with the decision to observe these patients. METHODS: This is a retrospective review of all trauma patients in a Level I university trauma center during a 5-year period. The patients were identified by a query of all pneumothoraces in our trauma registry. Those X-ray results were then reviewed to identify those who had OPTX. After developing an OPTX score on a small number, we retrospectively scored 50 of the OPTXs by taking the largest perpendicular distance in millimeters from the chest wall of the largest air pocket. We then added 10 or 20 to this if the OPTX was either anterior/posterior or lateral, respectively. RESULTS: A total of 21,193 trauma patients were evaluated and 1,295 patients with pneumothoraces (6.1%) were identified. Of the 1,295 patients with pneumothoraces, 379 (29.5%) OPTXs were identified. The overall incidence of OPTX was 1.8%: 95.7% occurred after blunt trauma, 222 (59%) of the OPTX patients had chest tubes and of the remaining 157 without chest tubes, 27 (17%) were on positive pressure ventilation. Of the 50 studies selected for scoring, the average score was 28.5. The average score for those with chest tubes was 34. The average score for those without chest tubes was 21. The positive predictive value for need of chest tube if the score was >30 was 78% and the negative predictive value if the score was <20 was 70%. Area under the receiver operator characteristic curve was 0.72, which was significant with p < 0.007. CONCLUSIONS: The OPTX score could quantify the size of the OPTX allowing the practitioner to better define a "small" pneumothorax. The management of OPTX is not standardized and further study using a more objective classification may assist the surgeon's decision-making. The application of a scoring system may also decrease unnecessary insertion of chest tubes for small OPTXs and is currently being prospectively validated.

Western Trauma Association Critical Decisions in Trauma: Management of rib fractures.

This is a recommended management algorithm from the Western Trauma Association addressing the management of adult patients with rib fractures. Because there is a paucity of published prospective randomized clinical trials that have generated Class I data, these recommendations are based primarily on published observational studies and expert opinion of Western Trauma Association members. The algorithm and accompanying comments represent a safe and sensible approach that can be followed at most trauma centers. We recognize that there will be patient, personnel, institutional, and situational factors that may warrant or require deviation from the recommended algorithm. We encourage institutions to use this as a guideline to develop their own local protocols.

Response to hurricane disasters.

Unlike most natural and man-made disasters, preparation and planning for hurricanes is possible and effective. Medical needs can be disparate, given the large geographic area involved and the often-prolonged recovery phase. All aspects of medical response, from first responders to hospitals, can directly and negatively be affected by the storm. Planning and practice, however, can drastically improve the outcome.
