Summary
Shivering is common during cesarean sections, affecting 42% of women. Anxiety, emergency delivery, and room transfer significantly increase shivering risk.
Area of Science:
- Obstetrics and Gynecology
- Anesthesiology
- Perinatal Medicine
Background:
- Intraoperative shivering is a common complication during cesarean sections.
- Identifying risk factors is crucial for improving maternal outcomes.
Purpose of the Study:
- To determine the incidence of intraoperative shivering in pregnant women undergoing cesarean section.
- To investigate potential risk factors associated with shivering during this procedure.
Main Methods:
- A prospective nested case-control study was conducted with 212 parturients.
- Data on shivering incidence, body temperature, and risk factors were collected at seven time points.
- Risk factors evaluated included pain, anxiety, emergency surgery, and patient transfer.
Main Results:
- The overall incidence of shivering was 42.0% (89/212).
- Anxiety, emergency delivery, and transfer from the delivery room were significant risk factors (ORs 1.77-3.83).
- Peak shivering incidence occurred post-skin disinfection; lowest body temperature was post-oxytocin.
Conclusions:
- Shivering is frequent during cesarean sections, peaking after skin disinfection.
- Anxiety, emergency delivery, and transfer increase shivering risk.
- These findings aid in developing targeted prevention strategies.

01:29Decreased Body Temperature
728
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...

01:26Factors Affecting the Risk of Infection
12.6K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

01:27Assessing Body Temperature - Rectal
7.0K
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...

2.3K
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...
