Guideline summary: appropriate use of tigecycline.

Tigecycline, the first of a new class of broad-spectrum antibiotics (the glycylcyclines), has been licensed in South Africa for the parenteral treatment of adult patients with complicated intra-abdominal infections (cIAIs) and complicated skin and soft-tissue infections (cSSTIs). This article serves as a summary of the guideline on the appropriate use of tigecycline, published in mid-2010 as a collaborative effort by representatives of the Association of Surgeons of South Africa, the Critical Care Society of Southern Africa, the Federation of Infectious Diseases Societies of Southern Africa, the South African Thoracic Society and the Trauma Society of South Africa.

Selective non-operative management of penetrating abdominal injury in Great Britain and Ireland: survey of practice.

BACKGROUND: The selective non-operative management of penetrating abdominal injury is gaining increasing acceptance. In Great Britain and Ireland, the management of trauma remains the responsibility of general surgeons. This study appraises the acceptance and utilisation of selective non-operative management strategies by British and Irish general surgeons, compared with trauma surgeons in the United States of America. METHODS: Electronic questionnaire survey of British and Irish consultant general surgeons and trauma surgeons in the United States of America. RESULTS: 139 British and Irish general surgeons and 75 US trauma surgeons completed the survey. 84.3% of British and Irish general surgeons and 94.4% of US trauma surgeons practise selective non-operative management of abdominal stab wounds, and 14.0% and 74.3% practise selective non-operative management of abdominal gunshot wounds. The management of those British and Irish surgeons who do practise selective non-operative management is broadly similar to that of US trauma surgeons, with the exception of the use of laparoscopy to examine the left hemidiaphragm following thoracoabdominal injuries, which is employed by fewer British and Irish general surgeons than US trauma surgeons. CONCLUSIONS: The selective non-operative management of abdominal stab wounds is generally accepted by British and Irish general surgeons. In contrast, few British and Irish surgeons are comfortable with non-operatively managing patients with abdominal gunshot wounds, reflecting both the rarity of this type of injury, and surgeons' training and experience. This proportion is unlikely to change until the management of torso trauma is recognised as a specialty, and services are concentrated in regional centres.

Impact of trauma societies on the clinical care of polytrauma patients.

INTRODUCTION: Trauma societies have an influence on the management and outcome of polytrauma. Its contributions include setting up standard definitions, trauma registries, evidence-based medicine guidelines, and the creation of educational tools such as specific courses of trauma care and decision-making. METHODS: Literature and web-based search of definitions and available information. RESULTS: The history of and accomplishments of trauma societies in the above-mentioned domains are reviewed, including the major trauma registries (Major Trauma Outcome Study, National Trauma Data Bank, The American Pediatric Surgical Association, the American Burn Association trauma, and the German Trauma Society trauma registries). Several learned societies in the field of trauma have created recommendations and/or guidelines concerning polytrauma (the Eastern Association for the Surgery of Trauma, The Society of Critical Care Medicine, and the German Trauma Society, Brain Trauma Foundation, and the Essential Trauma Care (EsTC) Guidelines). Several practical, hands-on courses and scoring systems for improving the quality of management of polytrauma patients have been founded and implemented in the past 35 years, including the Advanced Trauma Life Support (ATLS(®)) Course of the American College of Surgeons, the Definitive Surgical Trauma Care (DSTC(TM)) Course, the National Trauma Management Course (NTMC(TM) Course,) the Advanced Trauma Operative Management (ATOM) Course, and the European Trauma Course (ETC). CONCLUSIONS: Trauma and emergency care societies have made an elaborate, substantial contribution by developing trauma registries and creating specific guidelines courses on trauma care and decision-making.

Low central venous oxygen saturation in haemodynamically stabilized trauma patients is associated with poor outcome.

BACKGROUND: Central venous oxygen saturation (ScvO(2)) is suggested to reflect the adequacy of oxygen delivery, and the main objective of the present study was to determine whether ScvO(2) is associated with outcome in haemodynamically stabilized trauma patients. METHODS: Haemodynamically unstable trauma patients receiving a central venous line within 1 h of admission were eligible for inclusion in this prospective observational study. The mean arterial pressure (MAP), lactate and ScvO(2) were recorded at inclusion and every 6 h for 36 h or until lactate was <2.0 mmol/l and ScvO(2) was >75% in two consecutive measurements. Patients with a MAP of ≥70 mmHg were considered to be haemodynamically stabilized. The outcome measure was complications defined as infections, delta sequential organ failure assessment score of >0, and mortality. RESULTS: Fifty patients with a median new injury severity score of 27 (17-34) were analysed. Complications occurred in 33 patients. An association between ScvO(2) following resuscitation to MAP ≥70 mmHg and complications was detected with an odds ratio of 0.94 (95% confidence interval; 0.89-0.99). This association was also significant when adjusted for injury severity. The result implies that a low ScvO(2) value is associated with more complications. The optimal cut-off for ScvO(2) to discriminate between patients who did or did not develop complications was found to be 66.5% (56-86%). CONCLUSIONS: These data suggest that low ScvO(2) in haemodynamically stabilized patients is associated with a poor outcome and that ScvO(2) represents a potential endpoint of resuscitation in trauma patients.

Guideline: appropriate use of tigecycline.

INTRODUCTION: Tigecycline, the first of a new class of antibiotics, the glycylcyclines, was licensed in South Africa for the parenteral treatment of adult patients with complicated intra-abdominal infections (cIAIs) and complicated skin and soft-tissue infections (cSSTIs). METHODS: A multidisciplinary meeting representative of the Association of Surgeons of South Africa, the Critical Care Society of Southern Africa, the Federation of Infectious Diseases Societies of Southern Africa, the South African Thoracic Society and the Trauma Society of South Africa was held to draw up a national guideline for the appropriate use of tigecycline. Background information reviewed included randomised controlled trials, other relevant publications and local antibiotic susceptibility patterns. The initial document was drafted at the meeting. Subsequent drafts were circulated to members of the working group for modification. OUTPUT: The guideline addresses several important aspects of the new agent, summarising key clinical data and highlighting important considerations with the use of the drug. The recommendations in this guideline are based on currently available scientific evidence together with the consensus opinion of the authors. CONCLUSION: This statement was written out of concern regarding the widespread misuse of antibiotics. Its primary intention is to facilitate heterogeneous use of antibiotics as a component of antibiotic stewardship and to highlight the appropriate use of tigecycline in particular.

Damage control in the abdomen and beyond.

BACKGROUND: Damage control is not a modern concept, but the application of this approach represents a new paradigm in surgery, borne out of a need to care for patients sustaining multiple high-energy injuries. METHODS: A Medline search was performed to locate English language articles relating to damage control procedures in trauma patients. The retrieved articles were manually cross-referenced, and additional academic and historical articles were identified. RESULTS AND CONCLUSION: Damage control surgery, sometimes known as 'damage limitation surgery' or 'abbreviated laparotomy', is best defined as creating a stable anatomical environment to prevent the patient from progressing to an unsalvageable metabolic state. Patients are more likely to die from metabolic failure than from failure to complete organ repairs. It is with this awareness that damage control surgery is performed, enabling the patient to maintain a sustainable physiological envelope.

Are health professionals getting caught in the crossfire? The personal implications of caring for trauma victims.

OBJECTIVES: To investigate the long term psychological sequelae of treating multiple victims of traumatic incidents, such as violent crime and motor vehicle accidents, and to assess staff exposure to violent patients in the emergency department. METHODS: A self administered questionnaire booklet was distributed to all full time and part time staff working within the Johannesburg Hospital Trauma Unit during September 2002. Participation was voluntary. The questionnaire was specifically designed for the study as no relevant, validated questionnaire was found to be suitable. Psychological assessment comprised two standardised measures, the impact of event scale-revised and the Maslach burnout inventory. RESULTS: Thirty eight staff members completed the questionnaire, a response rate of 90%. Over 40% of respondents had been physically assaulted while at work and over 90% had been verbally abused. Staff reported a significant level of post-traumatic symptoms, evaluated by the impact of event scale-revised (median = 17.5, range = 0-88), as a result of critical incidents they had been involved in during the previous six months. At least half of the respondents also reported a "high" degree of professional burnout in the three sub-scales of the Maslach burnout tnventory-that is emotional exhaustion, depersonalisation, and personal accomplishment. CONCLUSIONS: Preventative measures, such as increased availability of formal psychological support, should be considered by all trauma units to protect the long term emotional wellbeing of their staff.

Bullet markers--a simple technique to assist in the evaluation of penetrating trauma.

Radio-opaque markers in penetrating trauma are useful in both the clinical evaluation of the injuries and in the permanent record of the location of the wounds. The use of an unfolded paperclip taped over the wound as a marker is recommended as a valuable adjunct in the radiological evaluation of penetrating trauma.

Critical decisions in trauma of the thoracic aorta.

Trauma to the thoracic aorta is a significant injury with a high mortality. This mortality is partly due to the delayed recognition of the condition. The increase of motor vehicle accidents and the use of firearms worldwide has resulted in an increase of the incidence of trauma to the thoracic aorta. Certain new developments in diagnosis and management have resulted in traditional methods being questioned. This review analyses current literature and data which we attempt to evaluate.

Gunshot injuries of the extrahepatic biliary ducts.

OBJECTIVE: To assess our management of gunshot injuries of the extrahepatic biliary ducts. DESIGN: Retrospective study. SETTING: Urban teaching hospital, South Africa. SUBJECTS: 17 patients who were found to have gunshot injuries of the extrahepatic bile ducts, January 1993-June 1998. INTERVENTIONS: Packing and damage control, staged repair, or definitive repair. MAIN OUTCOME MEASURES: Morbidity and mortality: Three of the 17 died intraoperatively or postoperatively from causes unrelated to the biliary injury. Of the 14 survivors, 3 were managed initially with packing and damage control, 7 by staged repair, and 4 by definitive biliary repair. Eleven patients had a Roux-en-Y biliary jejunostomy, of whom 1 developed a late biliary stricture related to a postoperative anastomotic leak. End-to-end anastomosis of the bile duct was done for 2 patients and they both developed late biliary strictures. Ligation of the injured duct and cholecystojejunostomy was done for I patient. CONCLUSION: Roux-en-Y biliary-jejunal anastomosis is appropriate in the treatment of gunshot injuries of the extrahepatic biliary ducts as there is always a degree of tissue loss and some debridement is required, making it difficult to do a tension-free anastomosis.

Evolving concepts in the management of colonic injury.

PURPOSE: The management of colonic injury has changed in recent years. This study sought to evaluate current surgical management of injuries to the colon in a busy urban trauma centre, in the light of our increasing confidence in primary repair and evolving understanding of the concepts and practice of damage control surgery. METHODS: A retrospective analysis was made of consecutive patients presenting with colonic injury from January 1 to December 31 1998. Patients without full-thickness lesions of the colon were excluded, as were patients who died within 24 h of admission. Demographic data, wounding patterns and clinical course were studied. RESULTS: One hundred twenty-seven patients were analyzed. Management without colostomy was achieved in 84% of cases. Patients who underwent diversion of the faecal stream had increased morbidity and hospital stay compared to equivalent patients who were repaired primarily. The important subgroup of patients who underwent damage control or abbreviated laparotomy is discussed. CONCLUSION: This study further strengthens the validity of direct repair or resection and primary anastomosis for colonic injury. Strategies to deal with the subgroup of patients at very high risk of postoperative complications are suggested.

The management of penetrating neck injuries.

In recent years, there has been a major increase in patients with penetrating injuries to the neck admitted to the Johannesburg Hospital. Pressure on resources led to increasing delays for surgery, and a policy of selective conservatism emerged. In common with other centers, mandatory exploration of all wounds that breach the platysma was found to be no longer necessary as it became clear that many penetrating wounds to the neck were best treated conservatively. A policy of blanket investigation of all nonoperated cases also matured toward selective investigation, directed by careful clinical examination. A retrospective study was made of all patients undergoing exploration for gunshot wounds or stabs to the neck at the Johannesburg Hospital Trauma Unit between 1994 and 1998. An overall mortality rate of 9% was mostly a reflection of severe, associated injuries. The evolution of the nonoperative management of cervical penetrating wounds is a good example of the validity of the concept of "selective conservatism." A distillation of the experience at a busy, urban trauma center is presented, with guidelines to manage these potentially lethal injuries.

[Penetrating trauma of the trunk]. / Das penetrierende Trauma des Körperstamms.

Trauma has been described as a "disease of bleeding" [45]. Recognition of acute blood loss after injury, and restoration of homeostasis is the cornerstone of the initial care of the badly injured patient. Hypovolaemia remains the most common cause of death among those killed in action during military conflicts [46] and, in the civilian arena, increasing numbers of patients are being encountered with penetrating injuries, even in societies where blunt injury have previously been the norm. Increased use of higher calibre weapons or with altered ammunition means some patients will present with exsanguinations and critical physiological instability. Successful outcomes after the treatment of patients with penetrating trauma depend on the integration of many agencies, from prehospital care, initial reception, assessment and resuscitation through the operating room, intensive care and post-injury rehabilitation. Recognition of the importance of time and adherence to sound trauma management principles with conservative management when appropriate should see further improvements in our treatment of this important group of patients. Reducing the incidence of these injuries is the responsibility of us all and must be the focus of all governmental initiatives.
