The amount of rest required after a lung puncture biopsy is related to whether the patient develops complications after the puncture and cannot be generalized. When a lung puncture biopsy is performed clinically, there is a chance of adverse reactions because the puncture needle has to enter the lung tissue and extract some lung tissue for pathological examination, which is an invasive lung examination. If the patient recovers very well after the puncture with no adverse reactions, rest for 1-2 days is usually sufficient, and care should be taken to avoid strenuous activity and coughing for 24 hours. If an adverse reaction occurs after puncture, such as the development of a pneumothorax, or intrapulmonary hemorrhage, rest for 2 weeks or more may be required. After the puncture procedure, patients should be careful to avoid water at the puncture site to avoid infection and to avoid spicy foods. If carrying a drainage tube, the drainage bottle must be lower than the position of the chest drain into the chest when moving.
