RESUMO
In severely ill newborns conventional methods of umbilical artery catheterization sometimes fail to achieve a functioning intravascular line. In 18 of 19 such newborns requiring umbilical artery catheters for optimal management, successful catheterization was attained using a cutdown procedure on the umbilical arteries. Vascular perforation within the anulus umbilicalis, tunica intima invagination ahead of an advancing catheter, and subintimal cannulation were defined as the causes of initial catheterization failure in all 19 newborns.

In 1977, 7% of the 38,855 infants born in Utah were estimated to have required a total of 27,439 special-care hospital days. About half (53%) were mildly ill; their average length of stay was 4.6 days, or 24% of the total hospital-days. Another 20% of the infants had intermediate illness, with a 12-day average stay, or 23% of the total hospital-days. The remaining 27% of the infants required intensive care and used 53% of the total hospital-days; their average length of stay was 20 days. As a total population, the state's 38,855 births generated a need for two beds per 1,000 annual live births in special-care facilities. The estimated bed need was: mild illness (Level I), 0.5 beds per 1,000 annual live births; intermediate illness (Level II), 0.5 beds per 1,000 annual live births; and intense illness (Level III), one bed per 1,000 annual live births. Results are based on the assumption that nonstudy births, 30% of the total, have needs proportionate to study births. The following considerations are necessary to extrapolate these bed needs to other populations: convalescence of intensely ill babies may require that up to 50% of their bed needs may be shifted to intermediate care; compliance with criteria for transport to the next level of care may not be 100% as assumed in the study, thus redistributing bed needs; census characteristically fluctuates in special-care nurseries (study results are reported for an unchanging daily census); and the low birth rate of a population is intimately related to the bed needs.

Neonatal back transport is defined as the return of previously critically ill neonates from Level III newborn intensive care units to Level II and Level I nurseries for intermediate and/or convalescing care. During 1980, 172 infants (65% of eligible infants) were back transported from a Level III nursery to both Level I and Level II community hospitals. Infants who were returned to Level II hospitals tended to be smaller at the time of transfer, were less frequently nipple fed, and more frequently required oxygen supplementation compared with infants returned to Level I hospitals. Back transport permitted physicians to defer 3,892 days of hospitalization for these infants to community hospitals, an equivalent savings of approximately ten hospital beds at full occupancy. This resulted in a 44% reduction in the need for services in the newborn intensive care unit. Back transport is an efficient means of dealing with overcrowding of Level III nurseries.

The convalescent course of 55 infants transported from a Level III hospital back to the community hospitals from which they were originally transported was compared with the course of 58 infants who convalesced in the tertiary center nurseries. The events in their prenatal course and acute neonatal course were similar, thus making comparisons of their convalescent course possible. Weight gain was greater among the transported infants for infants with birth weights greater than or equal to 2,000 g and comparable if birth weight was less than 2,000 g. Transported infants received fewer transfusions than their nontransported counterparts. Tolerance of feedings, the occurrence of apnea and bradycardia, and use and discontinuance of supplemental oxygen were similar in both groups. Major new health problems occurred in 27% of all subjects, 20% of transported infants and 32% of nontransported infants. Readmission to the tertiary center or a change in status to more intensive care in the tertiary center occurred in 10% of all infants, 7% of transported and 14% of nontransported infants. It was concluded that convalescing infants often presented new clinical problems, in similar numbers and severity whether convalescing in the tertiary center or after back transport to community hospitals. Community hospital care givers were considered alert to these new problems and to have provided appropriate care, including retransfer to the tertiary center when necessary.

One risk of transport of newborns to referral centers is hypothermia. Modern transport incubators have limitations in their ability to keep infants euthermic. As tested in the laboratory and during actual transport the Porta-Warm mattress extends the capability of the transport incubator to keep neonates euthermic by (1) reducing the time required to warm the incubator and (2) warming the incubator in cooler environements. The mattress is an effective adjunct to the transport incubator for keeping newborns warm during transport.

A prospective investigation was conducted to determine if infants with necrotizing enterocolitis had evidence of carbohydrate intolerance prior to the onset of clinical symptoms of advanced disease. Stool specimens were examined for fecal reducing substances with Clintest tablets from well, full-term infants and sick premature infants. Only two of 45 (4.4%) formula-fed, full-term infants demonstrated higher than 2+ fecal reducing substances. Ten of 14 (71%) formula-fed premature infants who developed necrotizing enterocolitis had higher than 2+ reducing substances detected in their stools. Daily measurement of fecal reducing substances can be a useful adjunct in the management of sick premature infants.

A home phototherapy program for healthy, term newborns with hyperbilirubinemia (n = 62) was implemented, and results were compared prospectively with a group of term neonates who met enrollment criteria but were treated in-hospital (n = 55). The purpose of the study was to prospectively assess the feasibility, safety, and effectiveness of home phototherapy in treating uncomplicated neonatal jaundice. Infants were required to be greater than 24 hours old and to weigh at least 2,270 g (5 lb). Enrolling physicians were instructed to select infants whose clinical diagnoses and bilirubin levels allowed an adequate margin of error for a trial of home phototherapy and whose parents were capable of managing the added responsibilities of home therapy. At the time the phototherapy equipment was delivered and set up in their home, parents received extensive instruction, including how to record pertinent ongoing data on a home flow sheet. Serum bilirubin levels were measured at least daily. The preponderant diagnosis listed by enrolling physicians was "physiologic jaundice." No parent reported significant complications, and no infant required rehospitalization. Bilirubin levels decreased as rapidly in the home group as in the hospitalized control group, and duration of treatment averaged 2.8 days. About $18,000 was saved by treating these 62 infants at home compared with in-hospital costs in our community. We found home phototherapy to be a feasible, safe, and effective alternative to in-hospital phototherapy for otherwise healthy, jaundiced infants with motivated and capable parents.

OBJECTIVE: Although numerous trials have demonstrated the efficacy of exogenous surfactant for prophylaxis or treatment of neonatal respiratory distress syndrome (RDS), optimum timing of administration remains controversial. One previous study showed that administration of calf lung surfactant extract immediately following birth, to neonates born before 30 weeks postconceptional age, was preferable to delaying administration until after development of RDS. The current study was designed to test a similar hypothesis for babies born between 29 and 32 weeks gestational age. DESIGN: One thousand three hundred ninety-eight neonates with obstetric estimates of 29 through 32 weeks' gestation were randomized to receive CLSE at birth or to wait until development of mild RDS. After exclusions for malformations and other factors, data from 1248 were analyzed. RESULTS: Prophylaxis was associated with less development of moderate RDS (7% vs 12%), less need for retreatment (5% vs 9%), less need for mechanical ventilation or supplemental oxygen during the first 4 days, and fewer deaths or less requirement for supplemental oxygen at 28 days (5% vs 9%). Although 1-minute Apgar scores were significantly lower in the prophylaxis group, the difference disappeared by the 5-minute score and there was no difference in the incidence of asphyxia-related complications. Sixty percent of the neonates assigned to early treatment received endotracheal intubation and 43% received calf lung surfactant extract at a median age of 1.5 hours. When data were analyzed by gestational age and birth weight subgroups, most of the differences could be attributable to babies born at 30 weeks or less or weighing less than 1500 g, probably because of the higher incidence of surfactant deficiency in this more immature subgroup.

During a two-year period, 21 premature infants (weight at birth, 680 to 2,340 gm) had operative closure of patent ductus arteriosus (PDA). The first 6 infants had ligation performed in the operating room (OR); the subsequent 15 had ligation in the Newborn Intensive Care Unit. There were no immediate postoperative deaths. Two infants died from problems presnet preoperatively within 30 days postoperatively. There were no infections. Technique in the unit utilizes an open warmer with local anesthesia and a paralyzing agent. By eliminating transportation to the OR one avoids problems with thermoregulation, loss of lines, malfunction of monitors, poorly controlled ventilation, and fluid overload. Additional advantages to ligation in the unit are that the infant is already monitored, intubated, and on a respirator, and that venous and usually umbilical arterial lines are in place. At the conclusion of operation, management is returned to the neonatologists for optimal continuity of care.

We reviewed medical records of inborn babies of < 30 gestational weeks who died before hospital discharge to identify the cause of death and age at death. We compared all surfactant-treated babies born during the first 19 months of our experience in a phase III trial of exogenous surfactant prophylaxis of respiratory distress syndrome with all untreated babies born during the 19 months immediately preceding the surfactant trial. The two groups were virtually identical in birth weight and gestational age. Mortality in all gestational age groups declined by half after the initiation of surfactant treatment. The mean age at death did not change significantly. Cases of early or late mortality did not change between the two periods. Exogenous surfactant prophylaxis does not significantly prolong the lives of extremely premature babies who are destined to die before hospital discharge.

The onset of hematochezia with the use of sodium polystyrene sulfonate enemas in an index case prompted us to review our experience with the use of such enemas in neonates. Sodium polystyrene sulfonate enemas were used in 20 of 2317 patients. Of these 20 patients, four (20%) had evidence of hematochezia temporally related to the use of the enemas. No episodes of such bleeding occurred in infants who were older than 29 weeks of gestation or larger than 1250 gm birth weight. In one case an autopsy performed within 2 days of the enemas showed extensive vascular congestion within the mucosa and submucosa with focal areas of hemorrhage. Approximately 20% sorbitol (1098 mOsm/L) was the vehicle for suspension of the sodium polystyrene sulfonate. On the basis of evidence regarding similar morbidities in adults, we are concerned that the hyperosmolar suspending agent, sorbitol, may be the cause of such pathologic conditions in the colon of susceptible infants.

The case of an infant with mesenchymal hamartoma of the chest wall is presented, and the role of conservative diagnostic and therapeutic intervention is emphasized. A large mass that involved the right hemithorax and chest wall was detected in utero on routine ultrasonographic studies and diagnosed as mesenchymal hamartoma by percutaneous fine needle biopsy at 4 days after birth. The mass did not enlarge after birth, but surgical debulking was necessary at 1 month because of progressive respiratory compromise. Tumor regrowth was noted over the ensuing 8 months, and a second debulking at 9 months has been followed by a 6-year interval without evidence of recurrence.

During the calendar year of 1974, the Intermountain Newborn Intensive Care Center at the University of Utah Medical Center had 603 admissions. A representative group of 293 charts were reviewed which indicated that 44% of these children were intubated from hours to weeks. The overall mortality rate for the 293 children was 29%. Eighteen of the 603 children were diagnosed as having subglottic stenosis. Fifteen of these children appeared to have acquired subglottic stenosis secondary to endotracheal intubation. Three children had congenital subglottic stenosis. Tracheostomy was necessary in the management of 15 patients. Ten of the 18 patients have survived and two of these patients still have tracheostomy tubes in place. The survival and thickness of the stenotic area are inversely proportional to the birth weight and the duration of intubation. Endoscopic excision, dilatation and stenting were techniques utilized in the treatment of these stenotic lesions. The extubation technique utilized is described. The factors involved in the production of acquired subglottic stenosis are presented along with suggestions to decrease the incidence of this problem in the intubated child.

We report two neonates in whom placement of a chest tube for pneumothorax was followed by hemorrhage, shock, and subsequent death. An autopsy of one of the patients led us to the conclusion that bleeding had occurred from lung perforation. The intercostal artery had been clearly severed and may have contributed to the hemorrhage. We discuss pathogenesis, diagnosis, and offer suggestions for proper placement of the tube.

We report preliminary experience with a newly designed chest tube (JCT), for evacuation of neonatal pneumothorax. The catheter has a unique pigtail confirguration at the distal end, intended to simplify placement and minimize chest wall and lung trauma by reduced tube size and depth and insertion. Thirty-eight JCTs were placed in neonates with pneumothoraces. Neonates' birth weights ranged from 400 to 3,595 grams. All 38 tubes immediately relieved clinical signs of pneumothoraces. Thirty-five (92%) tubes immediately fully evacuated the pneumothoraces as evidences on chest radiograph. Twelve pneumothoraces partially reoccurred at a mean of 24 hours following JCT placement. These tubes were either irrigated or replaced. This newly configured chest tube functions effectively in the treatment of neonatal pneumothorax.
