A retrospective review of 114 solid organ donors over a 6-year period (1982-1987) was undertaken to identify problems in organ donor management and determine outcome of donated organs. Admission GCS was less than or equal to 4 in 84% of the donors. Complications included hypotension (81%), multiple transfusion requirements (63%), diabetes insipidus (53%), DIC (28%), arrhythmias (27%), cardiac arrest requiring CPR (25%), pulmonary edema (19%), hypoxia (11%), acidosis (11%), seizures (10%), and positive bacterial cultures (10%). Only 18% of organs were procured within 3 hours of brain death; 23% were procured more than 6 hours later. Six patients excluded from this study suffered cardiovascular collapse before their organs could be retrieved. From 114 organ donors, consent was obtained to procure 224 kidneys, 77 livers, 62 hearts, 35 pancreata, and ten heart-lung units. All 224 donated kidneys were procured and 202 were ultimately transplanted. Of 77 donated livers, 32 were procured; 31 transplanted. Of 62 donated hearts, 38 were procured; 29 transplanted and nine used for valves. Ten heart-lung units were donated; six were procured and transplanted. Of 35 donated pancreata, 11 were procured; only five were transplanted. Reasons for failure of donated organs to be procured or transplanted included abnormal organ characteristics, lack of compatible recipients, unavailability of surgical teams, organ injury during procurement, intraoperative arrest, and anatomic limitations precluding multiple organ procurement. This study identifies characteristics of organ donors and common organ-threatening complications. Rapid and continuing resuscitation of clinically brain dead trauma victims is mandatory.(ABSTRACT TRUNCATED AT 250 WORDS)

Carboxypeptidase R (EC 3.4.17.20; CPR) and carboxypeptidase N (EC 3. 4.17.3; CPN) cleave carboxyl-terminal arginine and lysine residues from biologically active peptides such as kinins and anaphylatoxins, resulting in regulation of their biological activity. Human proCPR, also known as thrombin-activatable fibrinolysis inhibitor, plasma pro-carboxypeptidase B, and pro-carboxypeptidase U, is a plasma zymogen activated during coagulation. CPN, however, previously termed kininase I and anaphylatoxin inactivator, is present in a stable active form in plasma. We report here the isolation of mouse proCPR and CPN cDNA clones that can induce their respective enzymatic activities in culture supernatants of transiently transfected cells. Potato carboxypeptidase inhibitor can inhibit carboxypeptidase activity in culture medium of mouse proCPR-transfected cells. The expression of proCPR mRNA in murine liver is greatly enhanced following LPS injection, whereas CPN mRNA expression remains unaffected. Furthermore, the CPR activity in plasma increased 2-fold at 24 h after LPS treatment. Therefore, proCPR can be considered a type of acute phase protein, whereas CPN is not. An increase in CPR activity may facilitate rapid inactivation of inflammatory mediators generated at the site of Gram-negative bacterial infection and may consequently prevent septic shock. In view of the ability of proCPR to also inhibit fibrinolysis, an excess of proCPR induced by LPS may contribute to hypofibrinolysis in patients suffering from disseminated intravascular coagulation caused by sepsis.

Amniotic Fluid Embolism (AFE) is a rare obstetric catastrophe that occurs in approximately 1/50,000 pregnancies and has a mortality rate in excess of 80%. AFE is a condition that is poorly understood and often difficult to diagnose. We report a case of a healthy 27-yr-old gravid two, 35 wk gestation parturient with a previous Cesarean section two years previously, and presently admitted for emergent Cesarean section due to premature uterine contractions. Induction of general anesthesias was performed with no problem and a male preterm infant with Apgar 8 at 1 min was delivered. Amniotic fluid was bloody and 40% placental abruption existed. Following delivery of the placenta, patient suddenly became plethoric and O2 saturation began to decrease and no pulse could be palpated! Immediate CPR was successful but she was hemodynamically unstable and signs of right heart strain was obvious. Right jugular venous catheterization was performed, vasopressors were administered. After a two hours period of relatively stable vital signs, patient's reflexes returned to normal, however, profound coagulopathy on lab data was reported and she was treated with 10 unit Packed Red Blood Cells (PRBCs), 10 unit FFP and 8 unit platelets, Sodium bicarbonate, oxytocin and Methergine. The patient remained hemodynamically unstable while laparotomy-hysterectomy was performed to stop the bleeding. Unfortunately attempts were unsuccessful and patient died four hours later in ICU. Post-mortem findings showed signs of Disseminated Intravascular Coagulation (DIC), no fetal squamous cells in pulmonary vasculature were found and special staining of Cytokeratin marker shows no positive cells in lumen of vessels. The post-mortem diagnosis of AFE is challenging to forensic investigators and pathologists and can be confirmed by histological confirmation of amniotic fluid contents in the pulmonary vasculature, although they may be difficult to identify. In recent years it has been suggested that AFE is an anaphylactoid reaction to fetal antigens and an elevated serum tryptase level is increasingly being used to support the diagnosis. Sudden onset of cardiovascular collapse and early signs of right heart strain and fulminant DIC supports the diagnosis of AFE in this case, although no fetal debri could be find in pathologic staining.

Extracorporeal cardiopulmonary resuscitation (eCPR) has been well described as a rescue therapy in refractory cardiac arrest among patients with congenital heart disease. The purpose of this retrospective analysis of data from the Extracorporeal Life Support Organization was to evaluate outcomes of eCPR in patients with structurally normal hearts and to identify risk factors that may contribute to mortality. During the study period, 1,431 patients met inclusion criteria. Median age was 16 years. Overall survival to hospital discharge was 32%. Conditional logistic regression demonstrated an independent survival benefit among smaller patients, patients with a lower partial pressure of carbon dioxide (PaCO2) on cannulation, and those with a shorter duration from intubation to eCPR cannulation. A diagnosis of sepsis was independently associated with a nearly threefold increase in odds of mortality, whereas the diagnosis of myocarditis portended a more favorable outcome. Neurologic complications, pulmonary hemorrhage, disseminated intravascular coagulation, CPR, pH less than 7.20, and hyperbilirubinemia after eCPR cannulation were independently associated with an increase in odds of mortality. When utilizing eCPR in patients with structurally normal hearts, a diagnosis of sepsis is independently associated with mortality, whereas a diagnosis of myocarditis is protective. Neurologic complications and pulmonary hemorrhage while on extracorporeal membrane oxygenation (ECMO) are independently associated with mortality.
