Summary
Preoperative hypothermia affects 28% of day-surgery patients, with significant changes in peripheral body temperatures but no change in core temperature. Further research is needed to guide interventions.
Area of Science:
- Anesthesiology
- Surgical Patient Care
- Thermoregulation Research
Background:
- Hypothermia is a prevalent issue in surgical settings, posing risks to patients and increasing healthcare costs.
- Maintaining normothermia is crucial for patient safety and optimal surgical outcomes.
- Preoperative temperature monitoring is essential for preventing adverse events associated with hypothermia.
Purpose of the Study:
- To investigate the peripheral and core body temperatures of day-surgery patients during the preoperative period.
- To identify trends in body temperature changes from admission to the operating theatre.
- To assess the incidence of preoperative hypothermia in this patient cohort.
Main Methods:
- A cohort of 50 day-surgery patients was enrolled.
- Core and peripheral body temperatures were measured twice: upon arrival at the day-surgery unit and in the operating theatre.
- Paired t-tests were employed for statistical analysis of normally distributed temperature data.
Main Results:
- Significant temperature variations were observed in peripheral measurements, with upper body sites cooling and lower extremities warming.
- No statistically significant changes were detected in core body temperature during the measured interval.
- A concerning 28% of patients presented with temperatures below recommended levels upon reaching the operating theatre.
Conclusions:
- A substantial proportion of day-surgery patients experience suboptimal preoperative temperatures.
- The study highlights the need for further investigation into perioperative thermoregulation.
- Identifying optimal timing for therapeutic interventions to prevent hypothermia is warranted.

01:27Assessing Body Temperature - Rectal
10.4K
Rectal temperature measurement is considered the most precise method for assessing core body temperature and typically registers higher than oral temperature. For adults, the rectal thermometer should be inserted 1 to 1.5 inches into the rectum to obtain the most accurate reading.
Follow these steps for rectal temperature assessment:
Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection.
Step 2: Position the patient in a side-lying position to better visualize the rectal...

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.

Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.

01:29Decreased Body Temperature
909
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...
