This retrospective review of 83 infants undergoing CPR in the neonatal ICU of a teaching hospital found that 12 (14%) patients were discharged from the hospital and seven (8%) were alive at least 1 yr after discharge. Of these seven, five appeared neurologically intact. From another perspective, 41% (12/29) of the patients who survived at least 24 h after CPR were discharged alive. Factors significantly (p less than .05) associated with poor outcome included sepsis, oliguria 24 h before and/or after arrest, prematurity, and intraventricular hemorrhage. Variables significantly (p less than .05) related to good outcome were the need for intubation during resuscitation and the diagnosis of major congenital anomalies. Intraventricular hemorrhage was the single most powerful variable in the regression analysis. Outcome statistics from this study were strikingly similar to currently available adult data.

The perceptive physician can anticipate and prevent eclampsia. If possible, he should try to prolong preeclamptic pregnancies to the 37th week to avoid neonatal deaths from complications and prematurity. In some cases, preeclampsia strikes and progresses rapidly before the 30th week, however, and, in order to save the mother, the pregnancy must be terminated. If the preeclamptic woman deteriorates to the point where severe headache, epigastric pain, vomiting, and hyperreflexia exist, eclampsia is imminent. If she becomes eclamptic, clinicians must immediately begin to manage the convulsions with a sedative. Diazepam has proved successful which accounts for its widespread use in Great Britain and developing countries. Large doses given over a long period of time, however, adversely affect the newborn, e.g. respiratory depression. Another popular sedative is magnesium sulphate (in use for 50 years). Dangers of overdose can be avoided by testing the patella reflex every hour when magnesium sulphate is being administered intravenously: the reflex becomes null before serious toxic effects occur. If the systolic blood pressure exceeds 170mmHg, antihypertensives should also be given selectively to prevent cerebral hemorrhage. The preferred antihypertensive must act rapidly and predictably, with a wide margin of safety between the therapeutic and toxic dose. Hydralazine hydrochloride meets these requirements. Fluid and acid-base balances must be controlled to treat hypovolemia, oliguria, and acidosis. The longer delivery is delayed, the worse the outlook for mother and infant. Regardless of the type of delivery, clinicians must avoid hemorrhage and operative shock because eclamptics cannot tolerate blood loss. It is imperative that clinicians do not become so involved in saving the patient that they overtreat her, e.g., mixing antihypertensives.

Prevalence of renal insufficiency and renal failure of newborns in an intensive care unit is considerably high. Most patients have prerenal failure which is associated with the underlying disease, some have had heart surgery and only few patients have congenital renal malformation. In a retrospective analysis in our institution main risk factors were: prematurity, age < 10 days, obstetric complications, male gender, Cesarean delivery and pulmonary disease. We could not confirm, however, that asphyxia is significant for renal failure. Much more common than manifest renal failure is renal insufficiency in diseased newborns during intensive care. The cause is sometimes primary renal insufficiency as a harbinger of renal failure, but it is often iatrogenic, because fluid intake is inadequate, either unintentional or for a purpose. This strategy, however, conflicts with a conservative approach to renal insufficiency, which requires adequate fluid and caloric intake. A skilled approach to this situation demands a daily re-evaluation of the fluid regimen with regard to possible liberalization. If renal failure progresses dialysis may be indicated, but this remains controversial in neonates. However, with growing expertise, skill and adequate equipment, different techniques of dialysis nowadays can be applied even to small infants. Mortality in infants with acute renal failure ranges from 25 to 78%, but death is seldom caused primarily by renal disease. In our survey 0.9% in a total of 34% mortality was attributed to renal disease. Attention has to be paid to the bulk of diseased newborns, who experience only slight increase in serum creatinine in their early life with only mild (or even without) oliguria, who may be prone to residual renal morbidity as well as those, who have manifest renal failure.

Acute renal failure (ARF) is a common problem in the neonatal intensive care unit (NICU). In most cases, ARF is associated with a primary condition such as sepsis, metabolic diseases, perinatal asphyxia and/or prematurity. This retrospective study investigated the course of illness, therapeutic interventions, early prognosis and risk factors associated with development of ARF in the neonatal period. A total of 1311 neonates were treated in our NICU during the 42-month study period, and 45 of these babies had ARF. This condition was defined as serum creatinine level above 1.5 mg/dL despite normal maternal renal function. The data collected for each ARF case were contributing condition, cause and clinical course of ARF, gestational age and birth weight, age at the time of diagnosis, treatment, presence of perinatal risk factors and need for mechanical ventilation. The frequency of ARF in the NICU during the study period was 3.4%. Premature newborns constituted 31.1% of the cases. The mean birth weight in the group was 2863 +/- 1082 g, and the mean age at diagnosis was 6.2 +/- 7.4 days. The causes of ARF were categorized as prerenal in 29 patients (64.4%), renal in 14 patients (31.1%) and postrenal in 2 patients (4.4%). Forty-seven percent of the cases were nonoliguric ARF. Asphyxia was the most common condition that contributed to ARF (40.0%), followed by sepsis/metabolic disease (22.2%) and feeding problems (17.8%). Therapeutic interventions were supportive in 77.8% of the cases, and dialysis was required in the other 22.2%. The mortality rate in the 45 ARF cases was 24.4%. Acute renal failure of renal origin, need for dialysis, and need for mechanical ventilation were associated with significantly increased mortality (p<0.05). There were no statistical correlations between mortality rate and perinatal risk factors, oliguria, prematurity or blood urea nitrogen and creatinine levels. The study showed that, at our institution, ARF in the neonatal period is frequently associated with preventable conditions, specifically asphyxia, sepsis and feeding problems. Supportive therapy is effective in most cases of neonatal ARF. Acute renal failure of renal origin, need for dialysis, and need for mechanical ventilation were identified as indicators of poor prognosis in these infants. Early recognition of risk factors and rapid effective treatment of contributing conditions will reduce mortality in neonatal ARF.

In recent decades, emerging fungal infections have changed the clinical mycology scenario as a consequence of the advances in medical diagnostics and therapeutic procedures, long hospitalization times, and the growing number of individuals with debilitating chronic diseases and impaired immune systems. This report presents a 19 months old Brazilian female patient who developed a severe fungal sepsis by an uncommon yeast. She was admitted at the intensive care unit with severe pneumonia, bronchopulmonary dysplasia, and weight-for-age z score of less than -2. She remained more than 30 days in the intensive care unit where she had a femoral venous catheter placement, enteral nutrition, broad-spectrum antibiotic therapy, and prophylaxis with fluconazole. Moreover, pericardiocentesis was performed due to cardiac tamponade. She had a previous history of prematurity, cardiac surgery due to patent ductus arteriosus, and a long period of hospital stay. Despite the antifungal prophylaxis, two yeast isolates were recovered from blood and then identified by classical mycological methods and internal transcribed spacer (ITS) sequencing as Wickerhamomyces anomalus. Both isolates exhibited susceptibility to amphotericin B, ketoconazole, itraconazole, voriconazole, and fluconazole. Her clinical state worsened, presenting anasarca, epistaxis, and hemorrhagic suffusions in the mouth, sclera, oliguria, and bradycardia. Two days after the first positive culture, she presented a gradual reduction of the white blood cells count, with severe leukopenia and neutropenia. She died five days after.
