Damage control in trauma and abdominal sepsis

Damage control surgery, initially formalized <20 yrs ago, was developed to overcome the poor outcomes in exsanguinating abdominal trauma with traditional surgical approaches. The core concepts for damage control of hemorrhage and contamination control with abbreviated laparotomy followed by resuscitation before definitive repair, although simple in nature, have led to an alteration in which emergent surgery is handled among a multitude of problems, including abdominal sepsis and battlefield surgery. With the aggressive resuscitation associated with damage control surgery, understanding of abdominal compartment syndrome has expanded. It is probably through avoiding this clinical entity that the greatest improvement in surgical outcomes for various emergent surgical problems has occurred in the past two decades. However, with its success, new problems have emerged, including increases in enterocutaneous fistulas and open abdomens. But as with any crisis, innovative strategies are being developed. New approaches to control of the open abdomen and reconstruction of the abdominal wall are being developed from negative pressure dressing therapies to acellular allograft meshes. With further understanding of new resuscitative strategies, the need for damage control surgery may decline, along with its concomitant complications, at the same time retaining the success that damage control surgery has brought to the critically ill trauma and general surgery patient in the past few years.

Disparity Between Resident and Faculty Surgeons' Perceptions of Preoperative Preparation, Intraoperative Teaching, and Postoperative Feedback

PURPOSE The education occurring within the operating room is fundamental to the development of a surgical resident. The purpose of this study was to investigate differing perceptions of surgical residents and faculty in regard to preoperative preparation, intraoperative teaching, and postoperative feedback. METHODS A validated survey tool was slightly adapted, piloted, and then administered to the surgical residents and faculty of a university-based general surgery residency program. The wording of the survey was specific to either residents or faculty and consisted of similar questions with responses on a 5-point Likert scale (1: strongly disagree to 5: strongly agree). The responses of the 2 groups for each question were averaged and compared using Wilcoxon-Mann-Whitney test to determine significant differences. RESULTS In all, 27 residents and 30 faculty members completed the survey for a response rate of 100%. With respect to preoperative preparation, significant differences were found in perceptions about reading (4.22 vs 2.59; p < 0.001) and anatomy review (4.11 vs 2.31; p < 0.001) before the procedure. Considering intraoperative perceptions, significant differences were found with respect to teaching the operative steps (3.59 vs 4.06 p = 0.048), surgical skills (2.85 vs 3.78; p = 0.001), instrument handling (3.19 vs 4.00; p = 0.002), and surgical technique (3.44 vs 4.28; p < 0.001). Significant disagreement was found in the perceived effort of the faculty to act as a teacher in the operating room (3.56 vs 4.09; p < 0.007). Postoperatively, significant differences were found in perceptions of positive feedback (2.63 vs 3.34; p = 0.01) and feedback on areas to improve (2.78 vs 3.50; p = 0.009). CONCLUSIONS Although there is agreement on the need to improve intraoperative education, there is significant disparity in perceptions of preoperative preparation as well as intraoperative and postoperative feedback between residents and surgical faculty.

Damage control surgery: it's evolution over the last 20 years

In less than twenty years, what began as a concept for the treatment of exsanguinating truncal trauma patients has become the primary treatment model for numerous emergent, life threatening surgical conditions incapable of tolerating traditional methods. Its core concepts are relative straightforward and simple in nature: first, proper identification of the patient who is in need of following this paradigm; second, truncation of the initial surgical procedure to the minimal necessary operation; third, aggressive, focused resuscitation in the intensive care unit; fourth, definitive care only once the patient is optimized to tolerate the procedure. These simple underlying principles can be molded to a variety of emergencies, from its original application in combined major vascular and visceral trauma to the septic abdomen and orthopedics. A host of new resuscitation strategies and technologies have been developed over the past two decades, from permissive hypotension and damage control resuscitation to advanced ventilators and hemostatic agents, which have allowed for a more focused resuscitation, allowing some of the morbidity of this model to be reduced. The combination of the simple, malleable paradigm along with better understanding of resuscitation has proven to be a potent blend. As such, what was once an almost lethal injury (combined vascular and visceral injury) has become a survivable one.

Damage control for intra-abdominal sepsis.

With the success of damage-control surgery for the treatment of exsanguinating truncal trauma, it has been adapted to other surgical diseases associated with shock states, such as severe secondary peritonitis. The structured approach of damage control is easily adapted to and can incorporate the fundamental elements of the Surviving Sepsis Campaign. It is not meant to replace tried and true surgical principles, such as source control, but is a usable framework in managing the complicated circumstances seen with these patients.

Impact of Hypothermia (below 36°C) in the Rural Trauma Patient

BACKGROUND Hypothermia is an independent predictor of mortality based on urban studies. But this association has not been described in the rural setting. This studys purpose was to evaluate hypothermia as a cofactor to mortality, complications, and hospital length of stay (LOS) parameters in the rural trauma setting. STUDY DESIGN The National Trauma Registry of the American College of Surgeons database for our rural, Level I trauma center was queried for a 5-year period (July 2002 to June 2007) to identify adult trauma patients. Multivariate regression models were used to evaluate the association of hypothermia with mortality; infectious complications; organ dysfunction; and, among survivors, hospital LOS parameters. RESULTS Of 9,482 adult patients admitted, 1,490 (15.7%) patients were hypothermic. Hypothermia had an adjusted odds ratio of 1.70 for mortality (95% CI, 1.35 to 2.12; p < 0.001). After controlling for covariates, hypothermia was not significantly associated with infectious complications or organ dysfunction, except for arrhythmia (adjusted odds ratio, 1.40; CI, 1.03 to 1.90; p = 0.031). Hypothermia was not associated with a difference in ICU (p = 0.310) or ventilator (p = 0.144) LOS. But a slight increase in hospital days was noted in the hypothermic patient (hazards ratio, 0.890 for discharge; 95% CI, 0.838 to 0.946; p < 0.001). CONCLUSIONS Hypothermia is a common problem at admission in a rural trauma center. It is associated with an increase in hospitalized days but not with increased ICU or ventilator days among survivors. Other than arrhythmias, it was not significantly associated with other National Trauma Registry of the American College of Surgeons infectious or organ dysfunction complications. Hypothermia is an independent risk factor for mortality in the rural trauma patient.

Impact of hypothermia in the rural, pediatric trauma patient.

Objective: Hypothermia is an independent predictor of mortality in adult trauma studies. However, the impact of hypothermia on the pediatric trauma population has not been described. The purpose of this study is to evaluate hypothermia as a cofactor to mortality, complications, and among survivors, hospital length of stay parameters in the pediatric trauma population. Design: Retrospective review of a prospectively collected database (National Trauma Registry of the American College of Surgeons) over a 5-yr period (July 2002 to June 2007). Setting: A rural, level I trauma center. Patients: One thousand six hundred twenty-nine pediatric patients admitted with a traumatic injury. Interventions: None. Measurements and Main Results: Multivariate regression models were used to evaluate the association of hypothermia with mortality, infectious complications, organ dysfunction, and among survivors, hospital length of stay parameters. Of 1,629 pediatric trauma patients admitted, 182 (11.1%) patients were hypothermic (temperature below 36°C) on admission. Hypothermia had an adjusted odds ratio (AOR) of 2.41 (95% confidence interval [CI], 1.12–5.22, p = .025) for mortality. After controlling for covariates, hypothermia had associations with developing pneumonia (AOR, 0.185, 95% CI, 0.040–0.853; p = .031) and a bleeding diathesis (AOR, 3.14, 95% CI, 1.04–9.44; p = .042). The median days in the hospital, intensive care unit (ICU), and ventilator were longer in the hypothermic cohort; however, after controlling for covariates, hypothermia was not associated with differences in hospital days, ICU days, or ventilator days. Conclusions: Hypothermia is a common problem at admission among pediatric trauma patients. Hypothermia is associated with an increase in the odds of death and the development of a bleeding diathesis, while having decreased odds for developing pneumonia. While the length of stay indicators were longer in the hypothermic cohort among survivors, no significant association was noted with hypothermia for hospital, ICU, or ventilator days after controlling for confounders.

The elderly trauma patient: an investment for the future?

BACKGROUND The cost of care in elderly (ELD) trauma patients is high compared with younger patients, but the association between age and reimbursement relative to cost is less clear. The purpose of this study was to explore the relationship between total costs (TC) and reimbursement in young (YNG) and ELD trauma patients. METHODS The National Trauma Registry of the American College of Surgeons was queried for patients admitted to a level I trauma center between January 2002 and December 2004. YNG patients (18-64 years) were compared with ELD patients (> or =65 years) for mechanism of injury, Injury Severity Score, and outcome variables. Data obtained from the hospital cost accounting system included TC, total payment, and net margin (P-L). Virtually, all patients were reimbursed based on the fixed diagnostic-related group payment. RESULTS There were 641 ELD and 3,470 YNG patients included in the study. ELD patients were more commonly injured via a blunt mechanism than the YNG patients (97% vs. 83%; p < 0.001). The ELD were more severely injured (Injury Severity Score 14.9 +/- 10.8 vs. 13.3 +/- 10.9), developed more complications (54% vs. 34%), and died more frequently (17% vs. 4.7%; all p < 0.05). TC for the ELD were significantly higher than the YNG (
