Decreased Body Temperature01:29

Decreased Body Temperature

895
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...

Methods of reducing fever

1.1K
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.

Continuous Renal Replacement Therapy01:30

Continuous Renal Replacement Therapy

588
Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

Area of Science:

  • Critical Care Medicine
  • Nephrology
  • Biomedical Engineering

Background:

  • Hypothermia is a frequent adverse event during continuous renal replacement therapy (CRRT), occurring in over 40% of cases.
  • Hypothermia in intensive care unit (ICU) patients is linked to increased mortality.
  • Previous CRRT technology was associated with significant heat loss, contributing to hypothermia.

Purpose of the Study:

  • To evaluate the efficacy of a novel warming device in the current generation of CRRT systems.
  • To determine if the new CRRT system reduces the incidence of hypothermia compared to older systems.
  • To assess the impact of advanced blood warming technology on patient temperature during CRRT.

Main Methods:

  • A comparative study included ICU patients over 18 years old treated with CRRT at Skåne University Hospital.
  • Temperature data were collected hourly from both CRRT systems and patients.
  • Patient data were analyzed from November 2006 to August 2019, comparing older (Prismaflex) and newer (Prismax) CRRT systems.

Main Results:

  • The novel Prismax CRRT system showed a lower incidence of hypothermia (10.06% of patient hours < 36.0°C) compared to the older Prismaflex system (11.43% of patient hours).
  • The new blood warmer demonstrated significantly less heat loss, with a higher mean patient temperature (37°C vs 36.5°C) and a lower mean set return temperature (37.9°C vs 40.9°C).
  • Statistical analysis confirmed significant differences between the systems (Chi-Square P = .0063 for hypothermia incidence; P < .001 for temperature differences).

Conclusions:

  • The current generation CRRT system, featuring an improved blood warmer, significantly decreases the risk of hypothermia in critically ill patients.
  • This technological advancement facilitates achieving target patient temperatures more effectively during CRRT.
  • The findings suggest a substantial improvement in patient safety and thermal regulation with the newer CRRT technology.
