Body Temperature01:25

Body Temperature

5.0K
The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

Body Temperature

1.5K
Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C...

Increased Body Temperature01:25

Increased Body Temperature

7.5K
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...

Decreased Body Temperature01:29

Decreased Body Temperature

1.1K
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...

Equipments Used to Measure Body Temperature

1.9K
Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

Summary

Intraabdominal pressure during hyperthermic intraperitoneal chemotherapy (HIPEC) does not impact complications. However, elevated core body temperature (CBT) during HIPEC is linked to increased postoperative complications, highlighting CBT as a critical factor.

Area of Science:

  • Oncology
  • Surgical Oncology
  • Critical Care Medicine

Background:

  • Hyperthermic intraperitoneal chemotherapy (HIPEC) with closed-abdomen technique (CAT) may influence intraabdominal pressure (IAP) and core body temperature (CBT).
  • High IAP can lead to complications like decreased venous return and organ hypoperfusion.
  • Elevated CBT poses risks of multiorgan dysfunction, while low IAP/CBT may compromise HIPEC efficacy and lead to disease recurrence.

Purpose of the Study:

  • To investigate the correlation between intraabdominal pressure (IAP) and core body temperature (CBT) with postoperative complications in patients undergoing HIPEC.
  • To determine if IAP or CBT levels during closed-abdomen technique HIPEC influence patient outcomes.

Main Methods:

  • Continuous measurement of intraabdominal pressure (IAP) via catheter and core body temperature (CBT) via esophageal probe.
  • Comparison of postoperative complication rates across different IAP groups (low, target, high) and analysis of CBT as a continuous variable.
  • Inflow perfusate temperature set at 44°C, with a mean perfusate temperature of 42°C.

Main Results:

  • No significant difference in postoperative complications was observed between IAP groups.
  • No correlation was found between IAP levels and postoperative complications or prolonged hospital stay.
  • Elevated mean core body temperature (CBT) emerged as a significant positive predictor of postoperative complications (p=0.035).

Conclusions:

  • Intraabdominal pressure (IAP) during closed-abdomen technique HIPEC is not associated with increased postoperative complications.
  • Elevated core body temperature (CBT) during HIPEC is a significant risk factor for postoperative complications.
  • Monitoring and managing CBT during HIPEC is crucial for optimizing patient outcomes and potentially reducing disease recurrence.
