Summary
Hand immersion is an inaccurate method for checking surgical irrigation fluid temperature. Objective measurement tools are recommended to ensure patient safety and maintain homeostasis during procedures.
Area of Science:
- Surgical Irrigation Fluid Temperature Management
- Patient Safety in Surgical Procedures
- Thermoregulation in Anesthesia
Background:
- Surgical irrigation fluids are critical for maintaining homeostasis and patient care.
- Current practice relies on subjective hand immersion to check fluid temperature.
- Inaccurate temperature assessment can negatively impact exposed tissues and patient body temperature.
Purpose of the Study:
- To evaluate the accuracy of the hand immersion method for assessing surgical irrigation fluid temperature.
- To identify potential risks associated with subjective temperature checks.
- To advocate for improved methods in fluid temperature monitoring.
Main Methods:
- Two fluid sets were prepared at 37°C (physiologic) and 30°C.
- Participants assessed fluid temperature using hand immersion.
- Perceptions were categorized as too warm, too cool, or appropriately warm.
Main Results:
- Approximately 50% of participants perceived physiologic 37°C fluid as too warm for irrigation.
- Around 25% of participants considered cooler 30°C fluid to be appropriate.
- Significant discrepancies were observed between actual and perceived fluid temperatures.
Conclusions:
- Subjective hand immersion is an unreliable method for determining surgical irrigation fluid temperature.
- Objective, standardized temperature measurement is essential for accurate assessment.
- Implementing objective methods will enhance patient safety and optimize surgical outcomes.

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...

The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail...
