Lung puncture biopsy requires hospitalization. 1. Lung puncture biopsy is mainly to check whether there are serious lesions in the lungs. Before lung puncture biopsy, a series of tests need to be completed, such as routine blood tests, coagulation quadruple test, lung CT and electrocardiogram, etc., and only after the tests have clarified the specific conditions, will further lung puncture biopsy be considered, and after the operation, the patient will also be observed to see if there are any complications, and the relevant hospitalization procedures need to be carried out in advance. 2. Complications may occur after lung puncture biopsy, including bleeding, pneumothorax, etc., and even air embolism, which can have serious consequences. Hospitalization for lung puncture biopsy is conducive to postoperative observation, and once adverse reactions occur, timely treatment can be provided. Moreover, after the operation, pay attention to rest, can not drink or eat within two hours, and make sure to follow the doctor’s instructions for good postoperative care to ensure the safety of the patient’s life.
