The correct method of clamping the bile t-tube is intermittent clamping and adjusted to the specific situation. The correct method of bile duct t-tube clamping is firstly intermittent clamping, which is clamped for about 2 hours about five days after the operation, then released for 15 minutes, and clamped again for 2 hours, and repeated clamping and opening. The intermittent clamping process needs to observe the specific situation, such as whether there is fever, abdominal pain and other discomfort. If there is no discomfort, the following day, you can increase the clamping time, each time increasing about 3 hours, until complete closure. If there is fever, abdominal pain and other discomforts, further examination is needed to observe the presence of bile duct obstruction factors, and may not be able to continue clamping. Bile duct t-tube clamping should be carried out under the supervision of a doctor, and the clamping time should not be extended or shortened arbitrarily.
