摘要:

The experience of six referral trauma centers with 832 blunt splenic injuries was reviewed to determine the indications, methods, and outcome of nonoperative management. During this 5-year period, 112 splenic injuries were intentionally managed by observation. There were 40 (36%) patients less than 16 years old and 72 adults. The diagnosis was established by computed tomography in 89 (79%) patients, nuclear scan in 23 (21%), ultrasound in four (4%), and arteriography in two (2%). There were 28 Class I, 51 Class II, 31 Class III, two Class IV, and no Class V splenic injuries.Nonoperative management was unsuccessful in one (2%) child and 12 (17%) adults (p< 0.05). Failure was due to ongoing hemorrhage inl2 patients and delayed recognition of pancreatic injury in one patient. Of the 12 patients ultimately requiring laparotomy for control of hemorrhage, seven (58%) were successfully treated with splenic salvage techniques. Overall mortality was 3%; none of the four deaths was due to splenic or associated abdominal injury.This contemporary multicenter experience suggests that patients with Class I, II, or III splenic injuries after blunt trauma are candidates for nonoperative management if there is: 1) no hemodynamic instability after initial fluid resuscitation; 2) no serious associated abdominal organ injury; and 3) no extra-abdominal condition which precludes assessment of the abdomen. Strict adherence to these principles yielded initial nonoperative success in 98% of children and 83% of adults. Application of standard splenic salvage techniques to treat the patients with persistent hemorrhage resulted in ultimate splenic preservation in 100% of children and 93% of adults.

摘要:

As trauma systems have developed and board-certified in-house surgeons are now immediately available, enthusiasm has returned for thoracotomy as part of initial resuscitation. This study evaluated the impact of thoracotomy by board-certified surgeons during the resuscitative phase of treatment. Resuscitative thoracotomy, performed on patients in cardiac arrest within 20 minutes of arrival in the hospital, was undertaken in 113 of 4,752 patients over a 4 1/2-year period. Resuscitative thoracotomy added nothing to beneficial survival in patients with a blunt mechanism despite the addition of a board-certified surgeon. Survivors of penetrating injury had a probability of survival (P.) of 0.48. Most patients suffering penetrating deaths had severe and advanced physiologic derangements at the time of admission despite similar anatomic injuries to survivors.

摘要:

Recent clinical reviews have helped to clarify the role of Emergency Department (E.D.) thoracotomy in critically injured adults. However, guidelines in the pediatric population remain ill defined. The purpose of this report is to examine the yield of E.D. thoracotomy in patients ≤ 18 years of age to allow for a more cost-effective application of this heroic measure. From an 11-year experience of 689 consecutive E.D. thoracotomies, 83 patients (12%) were ≤ 18 years old. Mechanism of injury was blunt trauma in 57%, gunshot wound in 30%, and stab wound in 13%. Mean age was 15 years and 71% were male. Survival by injury mechanism was 9% (1/11) for stab wound, 4% (1/25) for gunshot wound, and 2% (1/47) for blunt trauma. Sixty-nine patients presented to the E.D. without vital signs and only one, a 16-year-old with stab wounds to the chest and abdomen, survived. In contrast, two (14%) among 14 patients presenting with vital signs were salvaged. As in adults, outcome was largely determined by injury mechanism and physiologic status on E.D. presentation. Blunt trauma, the predominant mechanism of lethal injuries in children, had a dismal outcome, with only 2% salvage and no survivors when vital signs were absent.This study demonstrates a similar outcome for E.D. thoracotomy in children compared to adults, and supports a selective policy of liberal use in penetrating injury irrespective of physiologic status but limited in those arriving lifeless following blunt trauma.

摘要:

We reviewed our experience with tracheal and bronchial trauma from 1977 to 1988. There were 22 patients with tracheobronchial injuries treated in this period. Seventeen (77%) of the injuries were due to penetrating trauma and five (23%) were due to blunt trauma. Thirteen patients had major associated injuries, including six esophageal injuries. The most common physical findings were tachypnea (13 patients) and subcutaneous emphysema (nine patients). Eight patients presented with airway obstruction. All patients with penetrating cervical tracheal injuries underwent neck exploration and primary repair. All blunt injuries were diagnosed by bronchoscopy. Three patients with blunt injuries were treated with primary repair. Two patients with blunt chest trauma and small bronchial tears were treated nonoperatively with good results. All three deaths (14% mortality rate) were due to associated injuries. We conclude that patients with penetrating tracheobronchial injuries should be managed by surgical exploration and primary repair, although selected patients with blunt injury may be treated nonoperatively.

摘要:

To ascertain morbidity and disability associated with vigorous attempts at limb salvage after lower extremity combined orthopedic and arterial injuries we reviewed more than 10,000 trauma admissions. Twenty-two patients (0.2%) suffered 14 blunt and eight penetrating lower extremity orthoarterial injuries. In all, more than 90 extremity operations were performed within 30 days of admission. The mechanism of injury, ISS, sequence of orthopedic and vascular procedures, use of temporary arterial shunts, the nature of the arterial reconstruction, length of ischemic time, and the presence of open fractures did not affect limb salvage or outcome. The presence of neurosensory/motor impairment and/or serious soft-tissue loss and injuries at or distal to the popliteal artery were associated with a high frequency of disability and amputation. Tremendous effort was expended to achieve limb salvage in the patients of this review. Patients who underwent amputation had the more uneventful hospitalizations and the lower rates of disability. The notion that limb salvage need be obtained in all patients at all costs may often lead to the triumph of technique and technology over reason.

摘要:

The records of 98 patients with transpelvic gunshot wounds from 1983 to 1988 were reviewed: 22 patients were admitted in shock and required aggressive resuscitation and immediate exploration, and 76 patients were normotensive and were evaluated with diagnostic peritoneal lavage, angiography, cystography, proctoscopy, CT scan, and contrast-enhanced CT enema in various combinations as indicated. Using this approach, 40 stable patients were observed without operation and discharged without complications.Fifty-eight patients were explored: 20 had both arterial and hollow viscus injuries. Thirty-nine major vascular injuries were evaluated: 27 were ligated and 12 repaired. Other injuries were colon, 27; including seven rectal perforations, multiple small bowel perforations, five bladder, one ovarian, four ureteral, three caval, three renal, and two distal aortic injuries. Colon injuries associated with vascular injuries were treated with colostomy and ligation of the vessel with extra-anatomic bypass when revascularization was required.Overall 12 patients died as a result of their injuries, a mortality of 12.2%. However, 50% of the patients who were admitted in shock died. Two external iliac artery injuries and two ureteral injuries were missed at initial operation.Penetrating trauma to the pelvis presents a serious challenge because of the complex anatomy of the region. Patients in shock have a high incidence of vascular injury and subsequent exsanguination, and associated visceral injuries may complicate their management. However, stable patients may be managed without operation, when appropriate diagnostic techniques fail to demonstrate an injury. Arterial ligation and extra-anatomic bypass should be considered for vascular injury with gross fecal contamination.

摘要:

Endogenous opiate peptides are released in early hemorrhagic shock and may mediate hypotension during hypovolemia. We compared the effects of naloxone alone versus incomplete volume resuscitation on survival and splanchnic blood flow. Dogs were bled to a MAP of 35 mm Hg for 2 hours. In eight dogs, shed blood was returned; eight dogs received naloxone (2 mg/kg bolus and 2 mg/kg/hr in 0.5 ml/kg/hr normal saline) with no shed blood returned. Seven dogs received normal saline alone without shed blood or naloxone and served as untreated controls. Untreated dogs survived a mean of 18.6 minutes. All other dogs survived for 180 minutes. Naloxone and shed blood were equally effective in improving hepatic and renal blood flow; gastric, intestinal, pancreatic, and splenic blood flow remained unchanged from shock values in both groups. These data indicate that in the face of hypovolemia naloxone improves survival and blood flow (ml/min/gm) to splanchnic organs despite no return of shed blood.

摘要:

Traumatic hemipelvectomy is a catastrophic injury resulting from violent blunt shearing forces which cause massive skin, bone, and soft-tissue destruction. The initial extent of the injury as well as the complexity of the consequent problems is staggering. As such it constitutes one of the major challenges seen by trauma surgeons.Patients surviving traumatic hemipelvectomy are rare. We found a total of 36 cases reported in this century. The University of California at Davis General Surgery Trauma Service admitted 9,369 major trauma victims from June 1985 to May 1988. During this 3-year period eight patients sustained a traumatic hemipelvectomy, of whom three survived. Given the complexity, yet rarity, of this injury, a review of the world literature was undertaken to compile collective experiences to aid surgeons in the management of this injury.
