'Damage control': an approach for improved survival in exsanguinating penetrating abdominal injury.

Abstract: Definitive laparotomy (DL) for penetrating abdominal wounding with combined vascular and visceral injury is a difficult surgical challenge. Physiologic derangements such as dilutional coagulopathy, hypothermia, and acidosis often preclude completion of the procedure. "Damage control" (DC), defined as initial control of hemorrhage and contamination followed by intraperitoneal packing and rapid closure, allows for resuscitation to normal physiology in the intensive care unit and subsequent definitive re-exploration. The purpose of the study was to compare the damage control technique with definitive laparotomy. Over a 3 1/2-year period, 46 patients with penetrating abdominal injuries required laparotomy and urgent transfusion of greater than 10 units packed red blood cells for exsanguination. Medical records were retrospectively reviewed for degree and pattern of injury, probability of survival, actual survival, transfusion requirements for the preoperative and postoperative phases, resuscitation and operative times, lowest perioperative temperature, pH, and HCO3. No significant differences were identified between 22 DL and 24 DC patients and actual survival rates were similar (55% DC vs. 58% DL). However, in a subset of 22 patients with major vascular injury and two or more visceral injuries (maximum injury subset), otherwise similar to the overall group, survival was markedly improved in patients treated with damage control (10 of 13, 77%*) vs. DLM (1 of 9, 11%) (Fisher's exact test, * p < 0.02). In preparation for return to the operating room, DC survivors averaged 8.4 units of packed red blood cells transfused and 10.3 units fresh frozen plasma over a mean ICU stay of 31.7 hours. Resolution of coagulopathy (mean prothrombin time/partial thromboplastin time 19.5/70.4 to 13.3/34.9), normalization of acid-base balance (mean pH/HCO3 7.37/20.6 to 7.42/24.2), and core rewarming (mean 33.2 degrees C to 37.7 degrees C) were achieved. All patients had gastrointestinal procedures at reoperation (mean operative time, 4.3 hours). We conclude that damage control is a promising approach for increased survival in exsanguinating patients with major vascular and multiple visceral penetrating abdominal injuries.

Damage control resuscitation: Directly addressing the early coagulopathy of trauma

Abstract: : Rapid progress in trauma care occurs when the results of translational research are promptly integrated into clinical practice. Experience with a high volume of severely injured casualties expedites the process. Historically, these conditions have converged during times of conflict, improving the care of combat casualties and subsequently that of civilian trauma patients. In the most severely injured casualties, we know that when the lethal triad of hypothermia, acidosis, and coagulopathy are present, death is imminent. Current teaching is to avoid reaching these conditions by using damage control surgery. However, conventional resuscitation practice for damage control focuses on rapid reversal of acidosis and prevention of hypothermia, and surgical techniques focus on controlling hemorrhage and contamination. Direct treatment of coagulopathy has been relatively neglected, viewed as a byproduct of resuscitation, hemodilution, and hypothermia, and delayed by blood banking logistics. Damage control resuscitation addresses the entire lethal triad immediately upon admission to a combat hospital. By demonstrating that in the severely injured the coagulopathy of trauma is present at admission, recent studies have brought back to light the importance of treating this disorder at an earlier stage. Reports of lactated Ringer s solution and normal saline increasing reperfusion injury and leukocyte adhesion lead one to conclude that the standard crystalloid based resuscitation guidelines in pre hospital trauma life support (PHTLS) and advanced trauma life support (ATLS) may worsen the presenting acidosis and coagulopathy in severely injured trauma patients, and possibly increase ARDS, SIRS, and MOF. The safety of withholding PRBCs in hemodynamically stable patients has been demonstrated,18 and the risks associated with blood transfusion are well described.

Management of the major coagulopathy with onset during laparotomy.

Abstract: An experience with 31 patients who developed major bleeding diatheses during laparotomy was reviewed. Management of the initial 14 patients was by standard hematologic replacement, completion of all facets of operation, and then closure of the peritoneal cavity, usually with suction drainage; only one patient survived. The subsequent 17 patients had laparotomy terminated as rapidly as possible to avoid additional bleeding. Major vessel injuries were repaired; ends of resected bowel were ligated; and holes in other gastrointestinal segments and the bladder were closed by purse-string sutures. One patient had a ureter ligated. Laparotomy pads (4-17) were then packed within the abdomen to effect tamponade, and the abdomen was closed under tension without drains or stomata. Following correction of the coagulopathy, the abdomen was re-explored at 15 to 69 hours in the 12 survivors. Definitive surgery then was completed: bowel resection and reanastomosis; ureter reimplantation; drains for bile, pancreatic juice, and urine; and stomata for bowel or urine diversion or decompression. Eleven of 17 patients, deemed to have a lethal coagulopathy, survived. This technique of initial abortion of laparotomy, establishment of intra-abdominal pack tamponade, and then completion of the surgical procedure once coagulation has returned to an acceptable level has proven to be lifesaving in previously non-salvageable situations.

Abbreviated laparotomy and planned reoperation for critically injured patients.

Abstract: The triad of hypothermia, acidosis, and coagulopathy in critically injured patients is a vicious cycle that, if uninterrupted, is rapidly fatal. During the past 7.5 years, 200 patients were treated with unorthodox techniques to abruptly terminate the laparotomy and break the cycle. One hundred seventy patients (85%) suffered penetrating injuries and 30 (15%) were victims of blunt trauma. The mean Revised Trauma Score, Injury Severity Score, and Trauma Index Severity Score age combination index predicted survival were 5.06%, 33.2%, and 57%, respectively. Resuscitative thoracotomies were performed in 60 (30%) patients. After major sources of hemorrhage were controlled, the following clinical and laboratory mean values were observed: red cell transfusions--22 units, core temperature--32.1 C, and pH--7.09. Techniques to abbreviate the operation included the ligation of enteric injuries in 34 patients, retained vascular clamps in 13, temporary intravascular shunts in four, packing of diffusely bleeding surfaces in 171, and the use of multiple towel clips to close only the skin of the abdominal wall in 178. Patients then were transported to the surgical intensive care unit for vigorous correction of metabolic derangements and coagulopathies. Ninety-eight patients (49%) survived to undergo planned reoperation (mean delay 48.1 hours), and 66 of 98 (67%) survived to leave the hospital. With the exception of intravascular shunts, there were survivors who were treated by each of the unorthodox techniques. Of 102 patients who died before reoperation 68 (67%) did so within 2 hours of the initial procedure. Logistic regression showed that red cell transfusion rate and pH may be helpful in determining when to consider abbreviated laparotomy. The authors conclude that patients with hypothermia, acidosis, and coagulopathy are at high risk for imminent death, and that prompt termination of laparotomy with the use of the above techniques is a rational approach to an apparently hopeless situation.
