A study of 9,135 persons injured between 1973 and 1984 and treated at any of 13 regional spinal cord injury care systems was conducted to compare their age-, sex-, race-, and cause-specific mortality rates with those of the general population. All subjects survived at least 24 hours. Follow-up was terminated in December, 1985 when 854 persons (9.3%) had died. Although many persons had multiple causes of death, the leading primary causes were pneumonia, nonischemic heart disease, septicemia, symptoms and ill-defined conditions, pulmonary emboli, and ischemic heart disease. During the study period, spinal cord injured persons were 82.2 times more likely to die of septicemia, 46.9 times more likely to die of pulmonary emboli, and 37.1 times more likely to die of pneumonia than comparable individuals from the general population. Though some cause-specific mortality rates for spinal cord injured persons have declined dramatically, many remain substantially above normal. Before life expectancies increase further, improved methods for preventing and managing these fatal complications must be developed.

Heart transplantation for congenital heart disease poses unique problems because of structural anomalies and previous corrective and palliative surgery. In the period between May 1985 and February 1992 a total of 231 orthotopic heart transplants were performed at our hospital -22 of these procedures were carried out in patients with congenital heart disease. The patient's ages ranged from 1 month to 51 years (median 10 years). There were 13 patients in the paediatric group (under 16 years) and 9 patients in the adult group (16 years or older). The diagnoses included univentricular connections (8 patients), complex morphology (4 patients), congenitally corrected transposition of the great arteries (TGA) (3 patients), hypoplastic left heart syndrome (2 patients), Fallot's tetralogy, tricuspid atresia, TGA, pulmonary atresia with intact ventricular septum and atrial septal defect (ASD) and ventricular septal defect (VSD). These patients had protected pulmonary circulation due to previous surgery or as a result of intrinsic pulmonary stenosis. Seventeen patients (77%) had undergone 29 prior operations (21 palliative and 8 corrective) including Blalock-Taussig shunts, pulmonary artery (PA) banding, ASD and VSD repair, Fontan procedure and Mustard operation. There were 2 early deaths in the paediatric group and 4 early deaths in the adult group, but no late deaths. The cause of death was multi-organ failure following uncontrollable haemorrhage in 3 patients, sepsis in 1 patient and donor organ failure in the 2 paediatric patients. Specific surgical manoeuvres were required to create the normal anatomical configuration. These included the rerouting of venous circulation, pulmonary artery reconstruction and atrial septation. Adequate donor tissue was taken to permit satisfactory reconstruction.(ABSTRACT TRUNCATED AT 250 WORDS)

The Nippon-Zeon (NZ) ventricular assist device is a sac type, air driven, heterotopic, external pump. Its performance has been evaluated in Japan as a bridge to myocardial recovery. Few data are available on the device as a bridge to heart transplantation. Since 1991, 10 patients (9 men) were bridged to heart transplantation with NZ, all in biventricular support. The mean age was 39 +/- 13 years (range, 21-60 years), mean body weight was 75 +/- 13 kg (range, 51-95 kg). Five patients had a dilated cardiopathy, and five were ischemic (three acute myocardial infarctions). Despite maximal inotropic support, including enoximone in seven, epinephrine in three, and intraaortic balloon pumping in one, eight patients were anuric, three were in acute hepatic failure, and three were intubated. Preoperative hemodynamic and biologic values were: cardiac index, 1.57 +/- 0.4 l/min/m2; pulmonary capillary wedge pressure, 34 +/- 5 mmHg; creatinine, 200 +/- 80 mumol/l; blood urea nitrogen, 17.5 +/- 8 mmol/l; total bilirubin 36 +/- 6 mumol/l; aspartate aminotransferase, 1,000 +/- 2,000 IU/l. In all patients, a biventricular assist device was implanted without the use of cardiopulmonary bypass. Improvement occurred immediately in all but one. Mean left ventricular flow was 4.5 +/- 0.8 l/min. Anticoagulation was maintained with intravenous heparin. Recently for bleeding was required in one case (10%), and two patients had positive blood cultures that were successfully treated. There was no mechanical failure. Hemolysis was not significant (lactate dehydrogenase, 378 +/- 50 IU/l; plasma-free hemoglobin below 10 mg/dl). Each device was free of thrombi and deposits at time of explantation. One patient died while on assist. Nine patients (90%) were transplanted after 11 +/- 8 days (range, 1-32 days). Three died early after transplantation, one of graft failure, two of sepsis. Six patients (66%) could be discharged. The follow-up ranges from 7 to 28 months. NZ is a simple, reliable, pneumatic device driven by a light, silent console; it can be rapidly implanted without cardiopulmonary bypass in patients in desperate condition who are awaiting cardiac transplantation. The difficulty of patient rehabilitation while using this device should limit the duration of support to weeks to allow the patient to be in optimal condition for heart transplantation.

Data were analyzed on 290 children admitted consecutively to the pediatric intensive care unit (PICU) of the Postgraduate Institute of Medical Education and Research in Chandigarh, India, in 1993 to examine the frequency, severity, risk factors, and mortality of hypokalemia (3.5 mEq/l serum potassium) and the efficacy of treatment. 43 (14.8%) children had 54 episodes of hypokalemia. Most (68.6%) episodes were moderate. Predisposing factors were the nature of primary disease (renal disease 19%, septicemia 19%, acute diarrhea 14%, and heart disease with congestive failure and meningoencephalitis 12% each), malnutrition (weight for age 80% in 72%), and treatment with drugs (diuretics 20%, beta-agonists 13%, and corticosteroids 11%). Diagnoses most common in hypokalemia cases were acute renal failure (25%), septicemia (22.8%), and acute severe bronchial asthma (20%). The most important predisposing factor for hypokalemia prior to hospitalization was poor oral intake (i.e., inability to replace adequate potassium) (27%). All 43 children received 4-6 mEq potassium/100 ml of intravenous fluids. Clinicians administered an infusion of 0.3 mEq potassium/kg/hour to 7 children (9 episodes) who had ECG changes of hypokalemia until the ECG became normal. Potassium levels returned to normal in all 9 episodes requiring rapid correction and in 40 of 45 episodes requiring slow correction. PICU patients with hypokalemia were more likely to die than PICU patients with no hypokalemia (25.6% vs. 10.9%; p 0.05; odds ratio = 2.34). Hypokalemia patients who received slow correction therapy were more likely to die than those who received rapid correction therapy (31% vs 0; p 0.05). Mortality was lower in PICU patients whose hypokalemia was corrected than in PICU patients whose hypokalemia was not corrected (13.5% vs. 100%; p 0.05). Based on these findings, regular monitoring and rapid correction are recommended to improve the outcome of hypokalemia.

Sixty-seven patients with brain abscess were managed over 19 years (1975-1993). Our series had a 2.5 to 1 male predominance; the age distribution was from 3 days to 81 years. The underlying conditions of hematogenic brain abscesses (n = 33; 49%) included lung infections (n = 16), heart disease (n = 4), sepsis (n = 10), and other foci (n = 3). Otolaryngologic infections led to the abscess in 10 cases; there were 9 traumatic abscesses. The causes remained unknown in 15 cases. There were 47 solitary abscesses (70%) and 20 multiple abscesses. The most frequent presenting signs and symptoms were neurologic deficits (n = 17), disturbances of consciousness (n = 14), seizures (n = 6), and headaches, meningism and vomiting (n = 13). Causative organisms were isolated in 39 cases (58%) and included staphylococci (n = 6), streptococci (n = 6), enterobacteriae (n = 2), and anaerobic pathogens (n = 9). The most reliable laboratory sign of inflammation was an elevated ESR (52/59 patients). With the advent of computed tomography, burr hole aspiration of the abscess with or without drainage was possible in 30 cases; the mortality in this subgroup was 9%. All 4 patients with surgical excision in the pre CT-era died. The mortality of patients treated with antibiotics only was 62% (18/29). Overall mortality was 37% (25/67), including 5 cases with post mortem-diagnosis of brain abscess. Good recovery was achieved in 29/42 survivors. Predictors of a poor outcome were the patient's age, the level of consciousness, multiple abscesses, polybacterial cultures, and a hematogenic etiology, but not the size of the abscess.

On the average, 10-15% of patients who undergo cardiopulmonary resuscitation (CPR) following a cardiopulmonary arrest in the hospital environment will survive to be discharged. The purpose of this study was to determine objective factors influencing patient outcome after CPR to determine who should be resuscitated and when to end CPR efforts. The records of 266 patients who underwent in-hospital CPR over a 3-year period were retrospectively analyzed with regard to age, gender, co-morbid conditions, setting of arrest, duration of resuscitation, initial pH and PO2 during resuscitation, and outcome of resuscitative efforts. Twenty-four (9%) patients survived to be discharged from hospital. Eighty-seven (33%) patients arrested in the intensive care unit, 77 (29%) on the ward, 91 (34%) in the emergency room, six (2%) in the cardiac catheterization laboratory and five (2%) in the operating room. There was no significant difference in survival based on location of arrest. Factors associated with a poor prognosis included age greater than 60, co-morbid disease (i.e. pneumonia, sepsis, renal failure, heart disease, etc.), an initial PO2 < 50 mmHg and CPR efforts extending beyond 10 min. Based on this data, guidelines regarding initiation and termination of CPR should be instituted in light of poor outcome in patients over 60 years of age with co-morbid conditions, specifically after 10 min of CPR.

Bidirectional cavopulmonary shunt is an alternative palliative procedure for patients with congenital cyanotic heart disease, specially those patients less than "ideal" candidates for a Fontan's procedure. We present our results with this shunt in patients with tricuspid atresia. Twenty patients with tricuspid atresia were operated on with this shunt, with these associated defects: 20 atrial septal defect, 17 ventricular septal defect, 10 pulmonary stenosis, 1 pulmonary atresia and 1 transposition of the great arteries. Sex: 10 males and 10 females; the age was 27 days to 6 years (mean 1.8 years), the weight was 3.2 kg to 24 kg (mean 10.7 kg), the mean pulmonary artery pressure was 11 to 24 mmHg (mean 17 mmHg), pulmonary vascular resistance was 1.5 to 5 UW (mean 3.1 UW). Postoperative oxygen saturation improved 15 to 120%. All patients survived the surgical procedure. Three patients died in the immediate postoperative period, 2 due to a complications in the postoperative period and 1 due to sepsis. There were two late deaths, 1 sudden death after 6 months of the shunt, and 1 due to sepsis after a Fontan's procedure. Four patients presented pleural effusion and 2 pericardial effusion, they resolved well. We have 15 patients alive and well, in functional class I, and minimal cyanosis. We can conclude that this surgical procedure is useful in the management of patients with tricuspid atresia.

Dysfunctioning of the heart forms part of the multiple organ dysfunction syndrome (MODS) in sepsis and SIRS. This acute septic cardiomyopathy is often underestimated in degree and relevance, although yet in fact 10% of all sepsis fatalities are due to intractable heart failure. This potentially reversible cardiomyopathy is characterized by a considerable pump failure, is not primarily ischemic, coronary blood flow being normal or even enhanced; left and right ventricle are enlarged as a consequence of an increased ventricular compliance. Damage of the heart can further be aggravated in case of an additional right ventricular impairment due to pulmonary hypertension in ARDS. SIRS-cardiomyopathy in non-infectious MODS has common traits with acute septic cardiomyopathy. The pathogenesis of heart disease in sepsis and SIRS is multifactorial, the endotoxin/TNF-alpha/NO/cGMP-cascade representing a main negative inotropic axis. Therapy of acute septic cardiomyopathy and SIRS-cardiomyopathy at present still is mainly symptomatic (volume substitution, inotropic/vasoactive agents), causal therapeutic principles are, however, put to test in the context of a comprehensive concept of causal sepsis treatment.

Primary repair of interrupted aortic arch and associated heart lesions was performed in 13 patients aged from 1 to 85 days. The surgery was performed through the midline sternotomy approach in extracorporeal circulation and deep hypothermia. Hypothermic circulatory arrest at 14 to 19 degrees C was used for reconstruction of the aortic arch. In all patients it was possible to perform a direct anastomosis between the ascendent and descendent aorta. At the same time closure of the ventricular septal defect was performed in 11 patients, closure of the atrial septal defect in 4, correction of persistent truncus arteriosus in 3, resection of subaortic stenosis in 2, arterial switch repair of transposition of the great arteries in 1, correction of double outlet right ventricle in 1 and patch closure of aortico-pulmonary window in 1 patient. Three (23.1%) newborns died in the early postoperative period: two from sepsis and one from multiple organ failure. Ten patients (76.9%) were followed up for 1 to 29 months postoperatively. All of them are in very good condition with a nonrestrictive aortic anastomosis. Primary one-stage repair of interrupted aortic arch and associated heart lesions is preferred to the two-stage repair in all newborns with this critical congenital heart disease.

Three patients presented with brain abscess associated with ventricular rupture. The origins of infection were sepsis, congenital heart disease, and unknown, and the organisms were Gram-negative cocci in one and Streptococcus species in two. Ventricular rupture occurred before administration of antibiotics and caused consciousness disturbance in all three patients. Continuous ventricle drainage was begun and antibiotics were directly administered into the ventricles. Aspiration and drainage from the abscess was also performed in two patients. Ventricular irrigation resulted in an excellent effect in one patient. The outcomes were excellent in two patients and fair in one. Aggressive ventricular drainage in the very early stage and direct intraventricular administration of antibiotics are very important to obtain a favorable outcome in patients with brain abscess and ventricular rupture.
