Why is it essential for an ST to check the temperature of saline irrigation during a craniotomy?

During a craniotomy, it is essential for a surgical technologist (ST) to check the temperature of saline irrigation to maintain body temperature. Hypothermia can occur during surgeries, particularly in neurosurgical procedures where large areas of the body may be exposed, and body temperature can drop significantly due to factors like anesthesia and environmental conditions in the surgical suite.

Using warm saline helps to minimize the risk of hypothermia, which can lead to complications such as increased bleeding, lengthened recovery, and altered drug metabolism. Keeping the saline at an appropriate temperature supports homeostasis and helps ensure optimal conditions for the patient throughout the procedure. This practice is a critical aspect of perioperative care, particularly in neurosurgery, where maintaining normal physiological parameters is paramount.
