Abstract
Damage control is well established as a potentially life-saving procedure in a few selected critically injured patients. In these patients the 'lethal triad' of hypothermia, acidosis, and coagulopathy is presented as a vicious cycle that often can not be interrupted and which marks the limit of the patient's ability to cope with the physiological consequences of injury. The principles of damage control have led to improved survival and to stopped bleeding until the physiologic derangement has been restored and the patient could undergo a prolong operation for definitive repair. Although morbidity is remaining high, it is acceptable if it comes in exchange for improved survival. There are five critical decision-making stages of damage control: I, patient selection and decision to perform damage control; II, operation and intraoperative reassessment of laparotomy; III, resuscitation in the intensive care unit; IV, definitive procedures after returning to the operating room; and V, abdominal wall reconstruction. The purpose of this article is to review the physiology of the components of the 'lethal triad', the indication and principles of abdominal damage control of trauma patients, the reoperation time, and the pathophysiology of abdominal compartment syndrome.

Abstract
A multimodality strategy, including damage control and angioembolization techniques, has been reported to reduce the mortality associated with surgery for complex blunt hepatic injuries. However, the indications for angiographic evaluation and embolization in patients who require surgery for hepatic injury remain unclear. We report a case of blunt hepatic injury requiring emergency laparotomy, which we treated by damage control surgery because of an inaccessible major venous injury and the fact that coagulopathy was stopping hemostasis. The decision to perform immediate postoperative angiography was based on the hemorrhagic response to Pringle's maneuver and its release after perihepatic packing during surgery. Hepatic angiography revealed extravasation from a branch of the middle hepatic artery, which was embolized successfully. Although the definitive indications for immediate postoperative angioembolization for hepatic injury have not been established, the hemorrhagic response to Pringle's maneuver and its release after perihepatic packing during damage control surgery is an indication for immediate postoperative angioembolization.

Abstract
BACKGROUND Hydroxyethyl starch (HES) has a known dose-dependant effect on coagulopathy. The purpose of this study was to determine the effect of HES on coagulopathy after a period of hemorrhagic shock. METHODS Anesthetized swine underwent a 15-minute, 40% blood volume hemorrhage (28 mL/kg) and a 1-hour shock period, followed by resuscitation with sham resuscitation (group I); 6% HES, 15 mL/kg (group II); 5% albumin, 15 mL/kg (group III); lactated Ringer's solution, 39 mL/kg, and 6% HES, 15 mL/kg (group IV); and lactated Ringer's solution, 39 mL/kg, and 5% albumin, 15 mL/kg (group V). Coagulation function was measured by bleeding time, prothrombin time, partial thromboplastin time, fibrinogen, platelet count, and thromboelastography. RESULTS Platelet counts decreased significantly (p < 0.05) in all resuscitation groups except the sham resuscitation group. A significant decrease in platelets, fibrinogen levels, and maximum amplitude on thromboelastography was related to a dilutional effect of the fluid given and not a result of HES at the dose tested. CONCLUSION The linear dose-related coagulopathic effects of HES when given at moderate doses does not seem to be worsened by prolonged periods of hemorrhagic shock. The coagulopathy seen during resuscitation from hemorrhagic shock seems to be a dilutional effect.

Abstract
With the growing understanding of the pathophysiology of exsanguination has come the evolution of extraordinary surgical techniques designed to improve survival. As the success of damage control has grown, so has its acceptance in the traditional surgical community. Our challenge now is to scientifically define patient selection, refine intraoperative techniques, and acquire a greater clinical and basic science understanding of the physiology of exsanguination and reperfusion injury in resuscitation. In these efforts, overall survival should continue to increase and morbidity should continue to decrease.

Abstract
BACKGROUND Intraoperative autotransfusion (IAT) has been implicated in anecdotal cases and experimental models to precipitate, aggravate, or exacerbate a coagulopathy. This study assesses this hypothesis. METHODS A retrospective database review of over 36,000 multispecialty cases of IAT during an 18-year experience was conducted with special reference to the occurrence of coagulopathy (disseminated intravascular coagulation [DIC]) in association with adult respiratory syndrome (ARDS). RESULTS The incidence of coagulopathy was low (0.05%). A total of 18 cases of DIC/ARDS were identified: 10 associated with ruptured aneurysms, 6 following massive trauma, and 2 after complex redo cardiac surgery. All 18 patients suffered shock and profound hypothermia. The mean transfusion requirement was 28 units. The mortality was 100%. CONCLUSION Although some degree of bleeding and clotting disorders are not uncommon in major cases, in our experience coagulopathy occurs infrequently and is a result of a complex interaction of shock, hypothermia, and multiple transfusions. It is our contention that these factors trigger the DIC, not the autotransfusor, and that the ARDS results from reperfusion injury following a profound ischemic event, associated in many cases with multiorgan failure.

Abstract
The influence of haemorrhage and blood transfusion on primary haemostasis, coagulation and fibrinolysis was investigated in ten healthy male volunteers. Acute loss of 10% of the blood volume did not give any significant alteration in thrombin- antithrombin III (TAT) complex and plasmin-alpha 2-antiplasmin (PAP) complex levels compared with a control series. The skin bleeding time with the Simplate II device was not altered after the 10% blood loss. Acute loss of 10% of blood volume followed by transfusion of packed red cells or stored plasma did not resulted in any significant change in bleeding time, TAT and PAP complex levels. It could be concluded that a controlled haemorrhage does not give any detectable changes of the platelet dependent primary haemostasis, blood coagulation and fibrinolysis. Transfusion of one unit of packed red cells or stored plasma does not seem to adversely affect the haemostasis.

Abstract
OBJECTIVE The authors review the physiologic basis, indications, techniques, and results of the planned reoperation approach to severe trauma. SUMMARY BACKGROUND DATA Multivisceral trauma and exsanguinating hemorrhage lead to hypothermia, coagulopathy, and acidosis. Formal resections and reconstructions in these unstable patients often result in irreversible physiologic insult. A new surgical strategy addresses these physiologic concerns by staged control and repair of the injuries. METHOD The authors review the literature. RESULTS Indications for planned reoperation include avoidance of irreversible physiologic insult and inability to obtain direct hemostasis or formal abdominal closure. The three phases of the strategy include initial control, stabilization, and delayed reconstruction. Various techniques are used to obtain rapid temporary control of bleeding and hollow visceral spillage. Hypothermia, coagulopathy, and the abdominal compartment syndrome are major postoperative concerns. Definitive repair of the injuries is undertaken after stabilization. CONCLUSION Planned reoperation offers a simple and effective alternative to the traditional surgical management of complex or multiple injuries in critically wounded patients.

Abstract
The influence of haemorrhage and blood transfusion on primary haemostasis, coagulation and fibrinolysis was investigated in rabbits. Acute loss of 20% of the blood volume gave a significantly shortened coagulation time (Lee-White method) but no detectable change in fibrinolysis (euglobulin clot lysis time) and primary haemostasis (primary haemostatic plug formation time in transected arterioles in rabbit mesenteric microcirculation). Acute loss of 20% of blood volume followed by blood transfusion resulted in a prolonged coagulation time and also in a prolonged primary haemostatic plug formation time, but no change in fibrinolysis. It could be concluded that the haemorrhage did not affect the platelet-dependent primary haemostasis but resulted in a shortened coagulation time. Blood transfusion seemed to affect adversely both the primary haemostasis and the shortened coagulation time induced by haemorrhage.

Abstract
In this survey of transfusion in surgery, we have attempted to provide the surgeon with an understanding of the problems associated with homologous transfusion and a practical knowledge of treatment strategies and alternatives designed to reduce homologous blood exposure. Such a review cannot be encyclopedic. Our hope is that it will serve the reader as a stimulus to examine his or her transfusion practices and as a guide for future self-learning.

Abstract
The frequency of infection in 197 patients undergoing elective colorectal surgery and having either no blood transfusion, transfusion with whole blood, or filtered blood free from leucocytes and platelets was investigated in a prospective randomized trial. Natural killer cell function was measured before operation and 3, 7 and 30 days after surgery in 60 consecutive patients. Of the patients 104 required blood transfusion; 48 received filtered blood and 56 underwent whole blood transfusion. Postoperative infections developed in 13 patients transfused with whole blood (23 per cent, 95 per cent confidence interval 13-32 per cent), in one patient transfused with blood free from leucocytes and platelets (2 per cent, 95 per cent confidence interval 0.05-11 per cent) and in two non-transfused patients (2 per cent, 95 per cent confidence interval 0.3-8 per cent) (P less than 0.01). Natural killer cell function was significantly (P less than 0.001) impaired up to 30 days after surgery in patients transfused with whole blood. These data provide a strong case against the use of whole blood transfusion in patients undergoing elective colorectal surgery.

Abstract
Massive transfusion may cause abnormalities of electrolytes, clotting factors, pH, and temperature and may occur in a scenario of refractory coagulopathy and irreversible shock. Identification of correctable variables to improve survival is complicated by the interplay of this pathophysiology. Temperature may be an under-appreciated problem in the genesis of coagulopathy. In vitro studies have demonstrated that platelet function and vascular response are critically temperature-dependent. We reviewed the records of 45 trauma patients without head injury or co-morbid medical illness who required massive transfusions. The mean Injury Severity Score was 55 +/- 6, a mean of 22.5 +/- 5 units of blood was transfused, and mortality was 33%. Nonsurvivors were more likely to have had penetrating injury (88% versus 55%), received more transfusions (26.5 +/- 9 versus 18.6 +/- 1, p less than 0.05), had lower pH (pH 7.04 +/- 0.06 versus 7.18 +/- 0.02, p less than 0.05), had lower core temperature (31 +/- 1 degree C versus 34 +/- 1 degree C, p less than 0.01), and had a higher incidence of clinical coagulopathy (73% versus 23%). Severe hypothermia (temperature less than 34 degrees C) occurred in 80% of the nonsurvivors and in 36% of survivors. Patients who were hypothermic and acidotic developed clinically significant bleeding despite adequate blood, plasma, and platelet replacement. Avoidance or correction of hypothermia may be critical in preventing or correcting coagulopathy in the patient receiving massive transfusion.

Abstract
The possibility of coagulopathy can be minimized by attending to certain general perioperative details to avoid hypothermia, hypotension-shock, and multiple transfusions. In this paper, we present our protocol for avoiding coagulopathy in vascular surgery. In the past 1 1/2 years, we have used perioperative plasmapheresis in 204 patients undergoing cardiac or aortic peripheral vascular surgery. Autologous platelet-rich plasma is transfused at the completion of the operation after heparin reversal. Our data show an approximate 50% reduction in homologous blood product requirement. Seventy-five percent of patients having aortic surgery received no homologous blood products during their hospital stay. For those undergoing cardiac surgery, there has been about a 45% reduction in the use of homologous blood products. In our experience, autologous platelet-rich plasma not only decreases the risk of transmittable disease, but promotes hemostasis.

Abstract
In a randomized prospective controlled trial involving 311 patients undergoing acute or elective colorectal surgery, the efficacy and safety of two different single dose and one triple dose regimen of antibiotic prophylaxis, as well as the influence of blood transfusion on postoperative infectious complications, were studied. Postoperative infectious complications occurred in a total of 59 patients (19.0 per cent). There were no major differences between the three treatment groups. Thirty-four patients (10.9 per cent) developed abdominal wound infection, 17 patients (5.5 per cent) intra-abdominal abscess and 16 patients (5.1 per cent) anastomotic leakage. Of 202 patients (65.0 per cent) requiring blood transfusion during hospitalization 57 (28.2 per cent; 95 per cent confidence limits of 23-36 per cent) developed infectious complications, whereas two non-transfused patients (1.8 per cent; 95 per cent confidence limits of 0.2 to 6 per cent; P less than 0.001) developed infectious complications. It is concluded that one single dose of antibiotic prophylaxis in acute and elective colorectal surgery is as protective as a triple dose regimen. The development of infectious complications despite antibiotic prophylaxis is strongly related to blood transfusion.

Abstract
To evaluate the prognostic influence of blood transfusion in cancer patients, transfusion data were reviewed on 468 radically operated patients (260 Dukes' B and 208 Dukes' C) with carcinoma of the rectum and the rectosigmoid. Data on whole blood and packed red blood cell transfusions were recorded together with a number of clinical, pathological and histochemical characteristics. The endpoint used was death with cancer. All patients were followed for 2-7 years or until time of death. Univariate statistical methods revealed a highly significant trend towards worsened prognosis with increasing volume of transfusion blood. However, this effect was insignificant when multivariate statistical methods were employed: patients receiving whole blood or packed red blood cell transfusions did no worse than expected from their clinico-pathological characteristics. It is concluded that in this series the observed association between transfusion status and prognosis is adequately explained by a multivariate prognostic model including well-established prognostic factors.

Abstract
Liver resection is an increasingly common procedure. Despite a wide variety of indications, the preoperative and postoperative care required is similar. Experience with liver resection and transplantation has brought to light the significant alterations in fluid and electrolytes, hemostasis, metabolism, and pulmonary function that may result. A thorough understanding of these changes is required to minimize the morbidity and mortality rates of these procedures. Postoperative hepatic failure is a devastating complication, and careful patient selection is required to avoid this. More work is needed to identify better methods of evaluating functional hepatic reserve.

Abstract
We found that reinfusion of shed mediastinal blood (SMB) after a cardiac operation was associated with laboratory evidence of disseminated intravascular coagulation. In view of this, we compared the effect of infusing washed or unwashed SMB on the coagulation profiles and blood use of two serial groups of patients undergoing cardiopulmonary bypass. We found that the results of testing for fibrin degradation products converted from negative to positive in 17 of 20 patients who received unwashed SMB versus 1 of 14 patients who received washed SMB (p less than 0.0001). Other coagulation studies did not reveal disseminated intravascular coagulation in either group, nor were there differences in blood use between the two groups. The unwashed SMB contained high titers of fibrin degradation products (mean reciprocal titer = 354 +/- 161) compared with washed SMB (mean reciprocal titer = 34 +/- 18) (p less than 0.01). Based on the volume of SMB infused, the amount of fibrin degradation products in unwashed SMB was sufficient to account for the positive fibrin degradation product assays after infusion in this group. We conclude that infusion of unwashed SMB may confuse the interpretation of tests for disseminated intravascular coagulation or fibrinolysis. As this could lead to unnecessary blood component use and is preventable by washing before infusion, we recommend that the routine infusion of unwashed SMB no longer be employed.
