Insights

Newborn infants, especially preterm neonates, risk dehydration and hypothermia due to fluid and heat loss. Tailoring the care environment to individual needs is crucial for managing these risks and improving infant outcomes.

Area of Science:

  • Neonatal physiology
  • Thermoregulation
  • Pediatric critical care

Background:

  • Maintaining fluid and heat balance is critical for newborn infants.
  • Preterm neonates are particularly vulnerable to dehydration and hypothermia due to immature skin and high insensible water loss.
  • These conditions significantly impact neonatal mortality and morbidity.

Purpose of the Study:

  • To review studies on neonatal water and heat exchange.
  • To highlight the influence of the care environment on fluid and heat balance.
  • To inform current nursing practices for newborn infants.

Main Methods:

  • Review of existing studies on neonatal water and heat exchange.
  • Utilized non-invasive measurements of insensible water loss.
  • Calculated various modes of heat exchange.

Main Results:

  • Immature skin in preterm neonates leads to significant water and heat loss.
  • The care environment critically affects the magnitude of water and heat exchange.
  • Individualized care, based on clinical status, maturity, and postnatal age, is necessary.

Conclusions:

  • Understanding neonatal water and heat exchange is vital for clinical practice.
  • Environmental control and individualized nursing care are essential for preventing dehydration and hypothermia in newborns.
  • Research in this area has positively influenced current neonatal nursing.

Role of Water in Human Biology01:27

Role of Water in Human Biology

Water is the one of the most significant components of the human body; it plays a crucial role in several physiological activities because of its unique physicochemical properties. Importantly, it helps to regulate body temperature and is the chief component of several body fluids.
Water's Solvent Properties
Since water is a polar molecule with slightly positive and slightly negative charges, ions and polar molecules can readily dissolve in it. Therefore, it is referred to as a solvent, a...
Decreased Body Temperature01:29

Decreased Body Temperature

A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by sustained extreme cold exposure, and severe...
Methods of reducing fever01:22

Methods of reducing fever

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Requirements for Human Life01:26

Requirements for Human Life

The Earth and its atmosphere have provided humans with air, water, and food, but these are not the only requirements for survival. Humans also require a specific range of temperature and pressure that the Earth and its atmosphere provides.
Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...
Mechanism of heat transfer01:19

Mechanism of heat transfer

Understanding heat transfer mechanisms is essential for understanding how our bodies maintain balance in different environmental conditions. When the environment is thermoneutral, the body is in a state of balance, neither using nor releasing energy to maintain its core temperature. However, when the environment is not thermoneutral, the body employs four heat transfer mechanisms to maintain homeostasis: conduction, convection, evaporation, and radiation. These mechanisms facilitate heat...

Methods of Sterilization I: Physical Methods

As used in a healthcare facility, sterilization destroys all microorganisms through physical or chemical methods. The physical method includes steam, dry heat, boiling water, and radiation.
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...
