Background: Exchange transfusion (ET) for severe neonatal hyperbilirubinemia (SNH) is frequently undertaken in lowand middle-income countries (LMIC), in sharp contrast to the prevailing practice in high-income countries. However, the criteria for initiating this procedure in settings with limited resources for treating infants with SNH have not been systematically explored. Objective: To identi...

Background. Severe hyperbilirubinaemia requiring exchange transfusion has become less common in recent years; however, kernicterus still occurs. The aim of this study was to review babies undergoing exchange transfusion for severe hyperbilirubinaemia in a Johannesburg hospital. Methodology. This was a retrospective review of babies who required exchange transfusion in both the neonatal and the ...

The temporal interval between flashing lights that is required to perceive nonsimultaneity decreases as the refractive error increases from 0 to +2 diopters. The interval then remains constant with further increases to 3 and 4 diopters. The results are discussed in terms of the relative increase of transient to sustained visual channels and of the increase in apparent movement.

Dhaded et al.(1) have recommended a cut-off level of 20 mg/dl for exchange transfusion in term babies with nonhemolytic jaundice. This is based on their observations that 21 out of 86 (25.8%) babies with bilirubin level of more than 20 mg/dl developed kernicterus in their study group. It is well known that apart from bilirubin levels per se, many other factors determine bilirubin toxicity. As t...

Kernicterus is a preventable but devastating neurologic disorder with life long complications. It is caused by severe and inadequately treated hyperbilirubinemia during the newborn period. In the present paper potential causes and risk factors for the occurrence of kernicterus related to the Thai health system that are responsible for the care of newborn infants before and after discharge are d...

The peroxidase method described in this paper measures non–protein-bound bilirubin by oxidation of the free fraction. The oxidation rate is slow compared with rapid dissociation of albumin-bound bilirubin. Thus, the unbound bilirubin can be estimated from the initial rate of decline in total bilirubin concentration. In the 1970s, severe neonatal hyperbilirubinemia and kernicterus were major cli...

Jaundice occurs in most newborn infants. Most jaundice is benign, but because of the potential toxicity of bilirubin, newborn infants must be monitored to identify those who might develop severe hyperbilirubinemia and, in rare cases, acute bilirubin encephalopathy or kernicterus. The focus of this guideline is to reduce the incidence of severe hyperbilirubinemia and bilirubin encephalopathy whi...

Jaundice is common in healthy newborn infants. It is the result of normal adaptive physiological processes and generally peaks in severity between 3 and 5 days after birth and then resolves over the next 7 to 10 days. When bilirubin rises to toxic levels, bilirubin encephalopathy and subsequent kernicterus can occur. Phototherapy is a well-established and safe treatment of neonatal jaundice. A ...
