Whether you can take a bath after hanging water depends on the specific situation of the patient. If the patient has undergone infusion treatment for fever, cold and other less serious diseases, after the infusion is finished, the patient can take a bath, but he should pay attention to protect the infusion site to avoid local infection after getting wet. Secondly, if the patient has just finished larger surgery, such as pancreatic and duodenal resection, pancreatic tail malignant tumor resection, liver malignant tumor resection, gastric cancer radical treatment, etc.. In this case, after the patient finished the infusion of liquid on the same day, it is not recommended for the patient to take a bath immediately because of the weakness and inconvenience of movement, and it is more prudent to wait for the patient’s condition to stabilize and the incision to heal well before giving the patient a bath.
