Zhuang Shu was an excellent doctor in " The Storm of Surgery ". He was very appreciative of Lu Chenxi's mother's use of hypothermal saline. Low-temperature physiological salt solution was a special type of physiological salt solution. Its temperature was lower than that of normal physiological salt solution. It could reduce the risk of cell damage by lowering the temperature of the body's extra-cellular fluid. Under such circumstances, the use of low-temperature saline solution could help Lu Chenxi's mother extend the operation time and reduce the risk of surgery. At the same time, it could also avoid the discomfort and side effects caused by high-temperature saline solution. Zhuang Shu believed that hypothermal saline was a very effective surgical method that could improve the success rate and safety of the surgery and reduce the patient's pain. He suggested that the doctor's suggestions and instructions should be strictly followed when using hypothermal saline during surgery to ensure the safety and success of the surgery.
