A report from the National Cancer Center (published in JNCC) shows that lung cancer has the highest rates of both new cases and deaths in China. Surgery using a tiny camera (thoracoscopic surgery) is a main treatment for early-stage lung cancer. However, this type of chest surgery carries a much higher risk of patients developing low body temperature during the operation compared to other surgeries. This is because: (1) The surgery is complex and takes longer； (2) The chest cavity is open and exposed to the cool operating room air; (3)General anesthesia affects the brain's ability to regulate temperature and widens blood vessels, causing faster heat loss.Studies show that low body temperature happens in about 65-73% of these chest surgeries, while the average for surgeries longer than 2 hours nationwide is only about 40%. Low body temperature during surgery isn't just a problem at the time. It also increases the risk of negative outcomes after surgery. As known, it worsens post-surgery pain and increases risks of complications, such as infections, heart problems and bleeding issues. A common pain control technique for chest surgery is injecting local anesthesia medicine near the spine (Thoracic Paravertebral Block or TPVB). This technique is very effective at reducing pain after surgery, both short-term and long-term. However, new research suggests this nerve block might cause blood vessels to widen, potentially making patients lose body heat faster during surgery. Because TPVB is used so often, it's hard to tell if low body temperature during surgery directly causes worse pain afterwards, or if the nerve block itself influences both temperature and pain. The potential connection between low temperature caused by TPVB and later pain is not yet clear. The objective of this study is to investigate how low body temperature during and around the time of surgery affects complications after surgery (such as infections, heart and lung problems, longer hospital stays, etc.) in patients undergoing thoracic surgery. The investigators also aim to find the relationship between low body temperature during surgery and the occurrence of pain after surgery.
Study Type
OBSERVATIONAL
Enrollment
144
A wireless body temperature transducer is located under the auxiliary. The body temperature is continuously monitored perioperatively.
Postoperative complications
Time frame: From date of the operation until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 30 days
Pain intensity measured by Numeric Rating Scale on a scale from 0 to 10, where 0 indicates no pain and 10 signifies the worst possible pain. Scores between 1 and 3 typically represent mild pain, 4 to 6 moderate pain, and 7 to 10 severe pain.
Time frame: From date of the operation until the date of complete remission, assessed up to 30 days
Length of stay
Time frame: From date of admission to hospital until the date of discharge, assessed up to 30 days
ICU admission rate
Time frame: From date of the operation until the date of discharge, assessed up to 30 days
30-day readmission rate
Time frame: From date of discharge until the date of readmission, assessed up to 30 days
