Summary
Intravenous paracetamol (acetaminophen) does not lower body temperature in newborns without fever. In febrile neonates, it effectively reduces temperature within two hours.
Area of Science:
- Neonatal pharmacology
- Pediatric pharmacodynamics
- Thermoregulation in neonates
Background:
- Intravenous paracetamol (acetaminophen) is approved for neonatal pain management.
- Pharmacodynamic effects, specifically on body temperature, remain unreported in neonates.
Purpose of the Study:
- To investigate the effects of intravenous paracetamol on body temperature in neonates.
- To determine if paracetamol administration impacts thermoregulation in this population.
Main Methods:
- A pooled analysis of body temperature recordings in neonates receiving intravenous paracetamol.
- Temperature monitoring via skin probe before and every 2 hours post-administration (up to 48 hours).
- Statistical analysis using repeated measures ANOVA and paired analysis.
Main Results:
- Analysis included 99 neonates (median weight 2.7 kg, postmenstrual age 37 weeks).
- No significant effect on body temperature was observed in normothermic neonates (n=93).
- In neonates with fever (n=6), a median temperature decrease of 0.8°C occurred within 2 hours post-administration (p<0.01).
Conclusions:
- Intravenous paracetamol administration does not induce hypothermia in normothermic neonates.
- Paracetamol effectively reduces fever in neonates, with maximum reduction observed within 2 hours.

01:25Increased Body Temperature
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in response to an infection or illness.
01:22Methods 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.

As a nurse, it is vital to understand the factors affecting body temperature to monitor variations and effectively evaluate deviations from regular.

01:29Decreased 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...
01:14Temperature Measurement Sites
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

01:17Pharmacokinetics in Pediatric Patients: Drug Distribution
Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight, compared...
