Puncture and drainage of abdominal abscesses is usually a therapeutic tool that can be performed under ultrasound guidance to drain pus and treat abdominal abscesses. Patients with abdominal abscesses can be treated by percutaneous puncture and tube drainage, which is used as a puncture point near the skin of the abscess to suction the pus, and after suction is completed, rinsing and injection of medication is given, and the catheter is fixed. For patients with a large number of abdominal abscesses, two catheters can be left in place under the advice of the doctor, one for rinsing, and the other for abdominal drainage, so as to achieve the therapeutic purpose. Patients with abdominal abscess drainage should pay attention to the smoothness of the drainage tube in daily life, avoid breaking or accidental pulling out, fix it properly, pay attention to observing the amount of drainage fluid as well as the change of its nature, and follow the doctor’s instructions to carry out regular flushing. It is recommended that patients who need to undergo puncture drainage of abdominal abscesses should go to the hospital for examination and choose reasonable treatment under the guidance of the doctor, and should not be negligent so as not to delay the condition.
