[Ethical attitudes in Spanish pediatric critical care units].

OBJECTIVES: To assess physicians' awareness and experience of ethical problems that arise when dealing with critically ill children in pediatric intensive care units (PICUs). MATERIAL AND METHODS: Questionnaires containing 20 questions about ethical dilemmas and attitudes related to the care of children admitted to PICUs were mailed to 43 PICUs in Spain. RESULTS: Ninety-five responses corresponding to 24 residents and 71 attending physicians were received from 21 PICUs. The occurrence of ethical dilemmas in the PICU was recognized by 96.8 % of the respondents. The most frequent method of solving these problems was through medical consensus (80 %), while family participation in the decision making process was highly variable. A total of 95.8 % of respondents stated that decisions to limit therapy were made in their PICU, although only one third of these decisions were written in the medical record. The most frequent form of therapeutic limitation was the do not resuscitate order. One third (32.6 %) of participants considered there were ethical differences between withdrawal and withholding of treatment. Attending physicians had greater experience of therapeutic limitation than did residents, but their opinions on the subject were similar. CONCLUSIONS: Ethical dilemmas are common in the PICU. In this setting, decisions about limitation of therapy are frequent, although many physicians admit to not being clear on this issue or on other aspects of clinical ethics. Family members' participation in the decision making process is insufficient in Spanish PICUs.

[Non-invasive ventilation in neonates with Ondine syndrome: a real indication?].

Ondine's syndrome is a congenital central hypoventilation syndrome due to a disorder in the autonomic control of breathing in the absence of any primary disease that would explain it. Noninvasive ventilation (NIV) has been reported to be effective in the management of these patients, thus avoiding the need for tracheotomy for prolonged mechanical ventilation. We describe our experience of NIV in infants with Ondine's syndrome. Two infants with Ondine's syndrome were transferred to our center for management and adjustment of therapy. On admission NIV (BiPAP VISION) was started with nasal interphase in S/T (spontaneous/timed) mode, which failed to provide suitable ventilation (PCO2 > 70 mmHg). Finally, tracheotomy for continuous mechanical ventilation was performed. Although NIV has been reported to be successful in some patients with Ondine's syndrome, its application in patients younger than 5 years does not seem to be the general norm of treatment.

[Coronary ischemia secondary to congenital anomaly of the left coronary artery].

Coronary artery anomalies constitute 2.2 % of congenital malformations of the heart. The most common abnormality is anomalous origin of the left coronary artery from the pulmonary trunk, also known as Bland-White-Garland syndrome. Clinical manifestations are due to myocardial ischemia caused by the creation of an arteriovenous shunt. The childhood type of this anomaly presents high mortality from heart failure. The adult type develops myocardial infarction, arrhythmias, sudden cardiac death or signs of congestive heart failure. Surgical repair is essential. Various surgical approaches are available and the treatment of choice is direct left coronary artery reimplantation in the aorta. An alternative technique is to create an aortopulmonary tunnel (Takeuchi technique). Marked improvement is usually observed after surgical repair. We report two cases of myocardial ischemia due to coronary anomalies.

[Pulse oximetry and capnography].

Noninvasive methods of monitoring are crucial in the management of intensive care patients, especially in the pediatric field. Pulse oxymetry measures arterial oxygen saturation in severely ill patients, allows oxygen requirements to be adjusted to the patient, reduces invasive gasometric studies and achieves continuous monitoring of the critically ill child. Motion and deficient tissular perfusion reduce the accuracy of the measured values, but more sophisticated pulse oximeters are more effective in preventing these artifacts. Capnometers are an excellent method of measuring end-tidal CO2 values in real time in intubated patients. Capnography produces a graphic curve of end-tidal CO2 while capnometry provides a numerical representation of this concentration. This technique is highly useful in the continuous monitoring of various respiratory problems and situations such as weaning or checking the correct placement of endotracheal cannulas.

[Mechanical ventilation in pediatrics (III). Weaning, complications and other types of ventilation. Noninvasive ventilation].

Noninvasive ventilation (NIV), i.e. without tracheal intubation, has been reintroduced for the treatment of respiratory failure to reduce the complications of mechanical ventilation. Nowadays, NIV with positive pressure is the preferred method, applied through a mask held in place by a harness. Several masks can be used (nasal, bucconasal facial) and a variety of means can be used to keep them in place. Many respirators can be selected, ranging from those traditionally used in the intensive care unit(ICU) to specific NV respirators and conventional ICU respirators with specific software for NIV. Many respiratory modalities can be used according to the respirator (biphasic positive airway pressure [BIPAP], proportional assist ventilation, pressure support, synchronized intermittent mandatory ventilation [SIMV], etc.). NIV is mainly indicated in exacerbations of chronic respiratory failure: neuromuscular diseases, pretransplantation cystic fibrosis, and obstructive sleep apnea syndrome. It is also indicated in acute respiratory failure: pneumonia, status asthmaticus, and acute lung edema. The main contraindications are a weakened airway protection reflex(absent cough reflex) and hemodynamic instabiity. The advantages of NIV derive mainly from avoiding the complications associated with invasive ventilation. NIV also presents some disadvantages, especially the greater workload involved to ensure good patient adaptation to the respirator. The most common sequelae of NIV are skin lesions due to pressure on the nasal bridge.

[End-of-life decision-making in critical care].

Introduction Termination of artificial life-support in critically-ill patients without chance of recovery or with severe damage is frequent in the intensive care unit (UCI). Patients and methodsWe studied the present situation concerning the withdrawal of life support in Spain using data collected over 10 years in referral hospitals with pediatric ICUs. Forty-nine patients were included, of which 43 had chronic diseases.ResultsThe most frequent causes of admission to the pediatric ICU in this type of patiens was respiratory failure followed by cardiovascular surgery. The family seemed to be a key element when taking a decision although in a few cases the medical team acted paternalistically. The most common ways of limiting life-support were withholding or withdrawing some treatments (mainly mechanical ventilation and vasoactive drugs) and implementing do-not-resuscitate orders. Sedation and suitable pain management were widely used in terminal care. After the decision to limit life-support was made, six patients were discharged from the pediatric ICU. ConclusionsAlthough each case should be treated individually, because of the wide variation found in the limitation of life-support, we suggest the need for common guidelines that could help the decision-making process.

[Moyamoya disease. A cause of vascular occlusion in childhood].

OBJECTIVE: The objective of this study was to review the cases of Moya-Moya diagnosed in our center. PATIENTS AND METHODS: We reviewed the Moya-Moya cases diagnosed from 1979 to 1997. We evaluated the following elements: age of clinical onset, sex, clinical features, complementary examinations, neuroimage, treatment and follow-up. RESULTS: Six patients were diagnosed. The first case appeared in 1979 and the last in 1997. These included four boys and 2 girls, with ages between 5 months and 14 years. The initial clinical feature in all six cases was acute hemiparesis, noting that in one case this was preceded by homolateral seizures. Neuroimaging revealed ischaemic infarction areas in brain CT or MNR. The diagnosis was based on angiography, where in four cases there appeared bilateral occlusion of the internal carotid, or of the anterior or middle cerebral arteries and in the other two there was a unilateral occlusion of the interior carotid and middle cerebral arteries. Regarding etiology, in four patients the dysfunction was due to either fibromuscular dysplasia of the carotid, neurofibromatosis, cranial trauma or to Down's syndrome. In the other two cases no other primary cause was found. CONCLUSIONS: Acute stroke is an infrequent disease of pediatric age patients, however it is necessary to do a thorough angiography study to rule out the Moya-Moya like vascular anomalies.

[Non-traumatic cerebral hemorrhage in childhood: etiology, clinical manifestations and management].

OBJECTIVE: Non-traumatic intracranial hemorrhage is a rare occurrence in children, with the most frequent etiology being vascular malformation. Our aim was to review the etiology and management of spontaneous cerebral hemorrhage in children. PATIENTS AND METHODS: We have reviewed the patients admitted to our intensive care unit (ICU) with spontaneous intracranial hemorrhage from 1980 to 1998. The etiology, symptoms and their clinical management were analyzed. RESULTS: Forty patients with non-traumatic intracranial hemorrhage were admitted during this time period. The mean age was 6.8 years and the male/female ratio was 2.4/1. This condition presented with a sudden onset in 83%. The most common form of presentation was headache, vomiting and altered consciousness. The most frequent etiology was vascular malformation (32.2%). Initial management was symptomatic and addressed the prevention or treatment of intracranial hypertension and seizures. Mortality was 38% and there were sequelae in 35%. CONCLUSIONS: Management of critical non-traumatic intracranial hemorrhage consists in preventing or treating cerebral hypertension. The monitoring of intracranial pressure, jugular oxygen saturation and transcranial Doppler allows an indirect measurement of cerebral blood flow. Prompt excision of the hematoma improves the outcome. In vascular malformations, endovascular embolization or radiosurgery are possible.

[Epidural hematoma in children. Prognostic factors. Analysis of 70 cases].

OBJECTIVE: The aim of this study was to analyze the causes of epidural hematoma in order to know its incidence in craneoencephalic trauma and establish prognostic criteria. PATIENTS AND METHODS: A retrospective study of 70 children with the diagnosis of epidural hematoma between 1990 and 1995 were studied. Clinical, radiological, chronologic variables and evolution were analyzed. RESULTS: The diagnosis was made during the first 4 years in 63% of the cases. Neurologic impairment was present at admission in only 33% of the patients. Ages ranged between 7 days and 17 years (mean age: 8 years). Of these patients, 82% were admitted to the PICU, 53% were ventilated and 19% needed ICP monitorization. Radiological findings on the first CT were skull fracture (68%) and temporoparietal epidural hematoma (66%), right-sided (63%). Other kinds of lesions were also recorded in the first and subsequent CTs. Three patients died, 63% recovered fully, 10% had serious sequelae and 23% had some degree of neurodisability. CONCLUSIONS: The following data correlated with death or neurological impairment: Multiple cerebral contusion (p = 0.002), brain edema (p = 0.05), GCS less than 8 on admission (p = 0.002), and shock (p = 0.003). On the other hand, neither surgical drainage volume, age, location of the hematoma, nor ICP values correlated with a poor prognosis.

[Infectious mononucleosis in childhood].

We present 42 cases of infectious mononucleosis caused by the Epstein-Barr virus in children. Patients were divided into two groups: those less than 4 years old and those 4 to 16 years of age. Splenomegaly was more frequent in young patients. Treatment with amoxicillin was associated with cutaneous rash. Heterophil antibodies were more frequent in patients older than four years of age. In 93% of the cases anticapside antibodies of IgM class were present. Complications were rarely encountered. Pneumonia and haemolytic anemia were present. We believe that anticapside antibodies of the IgM class should always be determined in patient younger than four years of age. If heterophil antibodies (Paul-Bunnell) and IgM are negative, we recommend that other specific serology related to the Epstein-Barr virus be determined in any age group.
