Neonatal Medicine

A healthy Neonate will be alert for the first hour following birth. Meconium production and breastfeeding help trigger involution of the uterus, which stimulates the release of natural oxytocin, which helps the uterus to contract. While some neonates are inactive at birth, most are alert during the first hour after birth. However, neonates can be restless or even sleepy if their mother was given pain medication late in labor.

Physiologic characteristics

Physiologic characteristics of neonates are different than those of older infants. Normal neonates have a thin layer of subcutaneous fat and close blood vessels to the skin. This means that their blood temperature is influenced by changes in the ambient temperature, as well as by the physiologic centers of their hypothalamus. Furthermore, their body surface-to-weight ratio is larger than that of older infants. Hence, neonates' respiratory and cardiac rates are lower than those of adults.

During this transitional period, neonates must undergo a series of physiologic adaptations to cope with their extrauterine environment. These adaptations include the mechanisms of thermoregulation and the consequences of hypothermia. The importance of knowing neonate physiology is crucial to the management of ill neonates. The authors of this new edition include 52 new authors and four new chapters. The text is a useful reference for any neonatologist.

Physical examination

The complete physical examination of a newborn should take place within the first 24 hours of life, after the infant leaves the nursery. The baby should be kept quiet for the examination. It should be observed from a distance, and its heart and pulse should be felt. If the baby is quiet, the physician can observe spontaneous activity. This type of physical examination will help the physician rule out any abnormality, and determine the appropriate interventions. The more experienced the physician, the better he will be able to recognize normal findings.

The initial physical exam of a newborn includes a review of the chart and daily growth. It also includes checking for tears and palpebral fissures. All newborns must undergo hearing tests before their first month, and the doctor will use an otoacoustic emission test or auditory brainstem response to check for the presence of hearing loss. A systematic head-to-toe examination should also be performed to rule out any congenital anomalies or birth trauma.

Treatment

Neonatal treatment for CP involves the repair of the heart. The goal is to maintain the infant's heart function until he or she reaches age 2. In the first 72 hours after birth, CP is reversible in a majority of cases. Other treatments include mitral valve repair or revascularization. While LIMA bypass grafting is uncommon for neonates, it is sometimes necessary. Here is an overview of the process.

Cerebral palsy is a debilitating neurologic motor disorder caused by several underlying mechanisms. Preterm neonates are at a greater risk for developing this disorder. Understanding these mechanisms may allow targeted treatment. Further research on the causes of CP is necessary to develop targeted therapies. This article discusses the underlying causes and possible treatments. This article provides an overview of some of the most common neonatal complications and their treatment.

Meconium production

A recent study found that meconium in newborn infants contains variable amounts of IL-1b, IL-6, and IL-8, as well as heme. These substances can trigger inflammation when instilled into cultured A549 cells. Although the exact mechanism behind meconium production is unclear, it is likely that meconium is involved in the development of chemical pneumonitis and in neonates.

Studies have indicated that meconium can activate the complement system, a component of the immune system, when presented with endogenous or exogenous structures. Two pathways of activation are known: the classical pathway and the lectin pathway. These pathways converge at the main component C3, which then proceeds to the terminal pathway, where it produces the inflammatory mediator C5a. This component has potential therapeutic implications. Here are some other aspects of meconium and neutrophil activation.

Blood sugar monitoring

Current recommendations recommend continuous glucose monitoring (CGM) of neonates for several days and weeks. Such intensive monitoring increases the likelihood of the newborn being discharged home without risk of hypoglycemia and may reduce hospital stay. In addition, real-time CGM may reduce the number of blood glucose tests and may encourage better management. This research is supported by the Addenbrooke's Charitable Trust. This article highlights some key points of CGM for neonates.

Glucose concentrations in neonates are often low during the first two hours after birth and are commonly reported as reaching a physiological nadir at two hours after birth. However, several studies have failed to establish this phenomenon. In healthy term infants, however, intermittent sampling has been used to monitor glucose concentration. The mean blood glucose concentration remains stable at 3.0 mmol/L (54 mg/dl) for at least the first week after birth, then gradually rises to 4.0 mmol/L or 50 mg/dl within a few weeks.
