Summary
Both hypothermia and hyperthermia are common in women during emergency caesarean sections. Accurate temperature monitoring is crucial for effective intra-operative management to improve patient outcomes.
Area of Science:
- Obstetrics and Gynecology
- Anesthesiology
- Maternal-Fetal Medicine
Background:
- Temperature regulation during emergency caesarean sections lacks evidence-based recommendations.
- Inadvertent peri-operative hypothermia and hyperthermia have significant adverse effects on mothers and neonates.
- Hyperthermia is linked to poor neonatal outcomes, increased obstetric interventions, and sepsis treatment.
Purpose of the Study:
- To determine the prevalence of hypothermia and hyperthermia in women undergoing emergency caesarean sections.
- To highlight the need for accurate maternal temperature monitoring in this population.
Main Methods:
- Multi-centre observational cohort study across 14 UK sites.
- Recruited 265 participants undergoing emergency caesarean section over 12 months.
- Maternal temperature measured using a zero heat-flux device, with primary endpoint in the recovery room.
Main Results:
- Prevalence of hypothermia (<36.0°C) was 10.7% and hyperthermia (>37.5°C) was 14.7% on recovery room admission.
- Temperature differences observed based on anesthesia type: spinal for hypothermia, epidural top-up for hyperthermia.
- Significant maternal temperature decrease of 0.20°C from delivery to recovery room admission (P<0.001).
Conclusions:
- Hypothermia and hyperthermia are prevalent in mothers undergoing emergency caesarean sections.
- Accurate temperature measurement is essential for effective intra-operative temperature management.
- Evidence-based strategies are needed to address peri-operative temperature dysregulation in this group.

01:27Assessing Body Temperature - Rectal
8.5K
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...

2.6K
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...

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.
