Tubocurarine, given as a single bolus, may be used safely for neuromuscular blockade in the neonate. The recommended dose is 250 mug/kg at birth, increasing to 500 mug/kg at 28 days of age. This dose should be reduced in the event of prematurity, acidosis or hypothermia, or when certain antibiotics or inhalation anaesthetic agents are present in the tissues. A single dose as described has a duration of approximately 1 h and it is only after this time that satisfactory antagonism can be obtained. The potency of pancuronium when compared with tubocurarine in the study is 6:1, from birth to 28 days.

A female black rhinoceros calf developed significant hypoglycemia (blood glucose, 30 mg/dL) and hypothermia (97 degrees F) within 48 hours of birth and refused to nurse. Normal gestation of the black rhinoceros is 15 months, but elongated hoof slippers and low birth weight (30 kg) suggested prematurity in this calf. Clinical symptoms of neonatal sepsis including lassitude and poor sucking continued in spite of the aggressive use of antibiotics, and the calf required mechanical ventilatory support on day 7. Nutritional support including enteral gavage feedings (Pedialyte/4 ounces of SMA [Wyeth Ayerst] with sucraflox) had been instituted and was supplemented with total parenteral nutrition on day 5. Central venous access was obtained via a jugular cutdown. The total parenteral nutrition included appropriate electrolytes and vitamins for the neonatal calf but did not include trace elements. The use of total parenteral nutrition by our zoos for therapeutic purposes is increasing. Experience with total parenteral nutrition in exotic animals such as the black rhinoceros is limited, yet this may be an important therapeutic modality in these animals, particularly those in danger of extinction.

An analysis of the causes of death in the neonatal nursery of the Port Moresby General Hospital in Papua New Guinea from 1982-1985 is presented, and conclusions were enumerated. The nursery has beds for 24 babies, subdivided into intensive care, infection and growing areas. Dormitory space for 12 mothers is available, and breast feeding is encouraged, whether by sucking, cup or tube: no bottle feeding is done. Up to 9 sisters staff the unit. A total of 2948 infants were admitted, including 831 cesarean births. 343 deaths occurred. 80 deaths were previable babies less than 1000 g. The neonatal mortality was 10/1000. The most common causes of death were septicemia or meningitis (24%), perinatal asphyxia (20%), respiratory distress syndrome (15%), congenital abnormalities (12%), meconium aspiration 7%, apnea of prematurity (7%). Other causes included pneumonia, hypothermia, intrauterine infection syndrome, cerebral hemorrhage and kernicterus. Note that hypothermia can occur in tiny babies, even in the tropics. Both respiratory distress and jaundice appear to be rare in melanesians compared to caucasians. Infections were due to tetanus, E. coli, S. aureus a Strep. faecalis, rather than the Group B hemolytic Strep. more often seen in the West. It was concluded that several inexpensive measures can be put in place to markedly enhance survival: train birth attendants to prevent perinatal asphyxia; maintain body temperature by available means; feed adequately, using expressed breast milk if necessary; maintain oxygenation properly using simple equipment such as a nasal catheter or perspex head box; prevent infection by scrupulous hand washing, cord care and overall cleanliness; manage neonatal jaundice.

Fifty-two premature infants underwent hemoclip closure of patent ductus arteriosus in the neonatal intensive care unit after a brief trial of fluid restriction and diuretics. Indomethacin was used in only four patients. The median time from diagnosis to operation was 3 days. There were no deaths directly attributable to operation. Nine operative complications developed in nine patients (17 percent). There were no surgical infections. Complications related to prematurity resulted in 20 deaths (38 percent). Patent ductus arteriosus closure in the neonatal intensive care unit prevented the complications of hypothermia, inadvertent extubation, and interruption of vascular access and monitoring. Early operative closure in the neonatal intensive care unit is the treatment of choice in most premature infants with patent ductus arteriosus.

A previous prospective study of neonatal mortality in babies receiving special care at the University College Hospital, Ibadan, revealed that respiratory failure associated with prematurity, perinatal asphyxia, sepsis, and congenital malformations were the major causes of high neonatal mortality. To improve survival, selective measures were taken to improve care of low-birth-weight infants and prevent or treat intrapartum and postnatal hypoxia, metabolic acidosis, hypoglycemia, and hypothermia. A change in the initial antibiotic management of suspected septicemia to the use of cloxacillin and an aminoglycoside was also introduced, based on the current knowledge of etiologic agents and their antimicrobial sensitivities. In the 5-year period (1976 to 1980), the neonatal mortality in babies weighing 2,500 g and more at birth dropped significantly from 1.2% to 0.7% (P less than .02). The case fatality rates from birth asphyxia and neonatal sepsis dropped by 48% and 32%, respectively. Despite therapeutic interventions, however, the neonatal mortality in babies with birth weight of 1,000 g or less, 1,001 to 1,500 g, 1,501 to 2,000 g, and 2,001 to 2,499 g remained unchanged at about 82%, 25%, 9%, and 3%, respectively. These results suggest that early identification of infants at risk of developing birth asphyxia or neonatal septicemia and institution of prompt and appropriate management could produce a significant reduction in mortality in infants of normal birth weight. Survival of low-birth-weight infants requires additional high technical, financial, and manpower resources, which most centers in developing countries cannot afford at the present time. Therefore, efforts are probably better concentrated on decreasing the incidence of low birth weight.

When sick newborn babies are transferred to Hammersmith Hospital they are collected from the referring hospital or from home by a paediatric resident doctor and a nurse. They prepare the baby for the journey by giving any urgent treatment required, for procedures are difficult to carry out in a moving ambulance. Babies who are likely to become apnoeic are intubated before transport so that ventilation can be started immediately if required. The baby travels in a portable incubator, and special attention is paid to prevention of hypothermia, adequate oxygenation, and respiration. Altogether 122 babies were transferred in 1969, the main reasons being prematurity, hyaline membrane disease, and apnoeic attacks. Five improved during the journey, 102 did not change significantly and 15 became worse. There was no evidence that travel per se harmed any of the babies, though in a few cases deterioration might have been prevented had observation and treatment been easier in the ambulance. Fifty-eight (47%) of the babies eventually died, but the group was a highly selected one with a high proportion of small, immature, and ill babies. We conclude that for very ill newborn babies the advantages of transfer to an intensive care unit probably outweigh the disadvantages of transport, provided that the precautions described here are taken.

The perinatal histories of 50 very low birthweight infants weighing 1500 g, or less, with necrotizing enterocolitis were compared with those of the remaining 325 very low birthweight infants who were admitted to this hospital during a four year study period. Many factors previously reported to be associated with necrotizing enterocolitis were found with equal frequency in both groups of babies. The only adverse factor which was more frequently present in patients with necrotizing enterocolitis was hypothermia on admission to hospital. Those infants who developed severe necrotizing enterocolitis also had a higher incidence of polycythaemia. A further controlled study which examined feeding practices showed that the timing, type, and volume of milk feeding were not different in infants with necrotizing enterocolitis and matched controls. Prematurity is clearly the greatest risk factor which predisposes to the development of necrotizing enterocolitis and most of the factors previously implicated in the aetiology may simply represent the descriptive characteristics of a population of sick, very low birthweight infants.

Yellow staining of central nervous system (CNS) nuclei occurs in the brains of some neonates, despite low levels of serum bilirubin. Two conditions appear to be important in the evolution of this form of kernicterus: prematurity and asphyxia. In a seven year retrospective study of a large neonatal autopsy population, 102 cases had kernicterus as indicated by selective macroscopic yellow staining and microscopic damage within specific CNS nuclei. Neuropathological study disclosed minor variations and numerous similarities in the manifestations of kernicterus in the asphyctic premature neonate with low levels of serum bilirubin, as compared to kernicterus in the full-term neonate with high levels of serum bilirubin. Acidosis, hypoxia, hyperoxia, hypothermia and sepsis have been considered significant risk factors, but recent comparative clinical studies have not defined predictive indices. Analysis of this disorder is difficult because of the concurrence of other complications of asphyxia and its pathological correlates in premature infants. Diagnostic difficulties are also compounded by variations in the definitions of kernicterus as used by different investigators.

An extensive study was undertaken in northern France from January 1st to May 31st 1978, concerning the transfer of neonates from maternity hospitals to specialized units. Analysis of 250 children whose birth weight was below 2,000 gm showed that several risk factors could be taken into account to reduce neonatal mortality in this area. Prematurity (22% children weighing less than 1,500 gm in those discharged alive, 54% in the dead), neonatal distress (36% versus 61% of resuscitation) hypothermia (7% versus 23% with temperature below 34 degrees 6 at the time of admission), the need for an other transfer (1% vs. 12%) seem to be features highly related with poor prognosis. This stresses the importance of the prevention of prematurity, of proper management of the babies in the maternity hospital, of the conditions of transport and of the choice of the neonatal unit.
