A 7 mm mixed ground glass nodule can usually be discharged from the hospital in 3 to 6 days after surgery, or relatively longer if complications occur during the procedure. Molar glass nodule surgery is usually performed by thoracoscopic surgery, which is minimally invasive and therefore relatively less invasive, and you can usually be discharged from the hospital in 3 to 6 days. The 7 mm mixed ground glass nodule surgery involves anatomical removal of the lobe or segment of the lung localized to the ground glass nodule, which maximizes the preservation of healthy lung tissue while avoiding infiltration. If complications such as incision infections, respiratory infections, or air leakage occur after the surgery, then the time to discharge from the hospital will be relatively longer. After the 7 mm mixed ground glass nodule surgery, you need to pay attention to wound care, regularly clean and disinfect the wound with iodine vapour to avoid infection, and seek medical attention if any discomfort occurs, so as to avoid delaying the condition.
