How to treat liver abscess with puncture needle catheter drainage?

Needle catheter drainage "treatment of "liver" abscess" Use a Y-shaped trocar with an inner diameter of 0.5 cm and a common B-mode ultrasound probe to determine the location, size, direction and depth of the abscess, local anesthesia, and a general puncture needle to try out For pus, the pus is routinely sent for bacterial culture and drug susceptibility testing. Use a Y-type trocar to slowly insert the needle, pointing to the center of the abscess. After feeling of loss, withdraw the needle core, that is, pus overflows from the side hole. A drainage tube with a diameter of 0.5 cm is inserted, the drainage tube has a side hole to drain the pus, the silk thread is fixed to the skin, and the negative pressure suction bottle is connected. Routinely use 0.2% "metronidazole" and "glucose" injection 250ml plus 240,000 U of gentamicin needle to rinse once a day, and perform regular B-mode ultrasound "re-examination" to determine the size of the abscess cavity, whether the drainage is unobstructed and whether closure. When the abscess is significantly reduced, the diameter is less than 1cm, no pus is drawn, and the patient's general condition is good, remove the drainage tube.

Surgical treatment of liver abscess is mainly "bacterial liver abscess". With the development of imaging diagnosis such as CT and ultrasound, puncture drainage or catheterization of liver abscess has become a common clinical treatment method, and most patients undergo This method has satisfactory results. Therefore, traditional treatment methods use high-dose antibiotics, and surgical drainage is subject to certain restrictions. The percutaneous drainage technique is simple to operate, safe, and has fewer complications. Compared with simple puncture drainage, it drains thoroughly and avoids the drawbacks of repeated punctures. Liver abscess puncture drainage is not suitable for all patients. Its indications are: a single liver abscess with a clear boundary, with a diameter greater than 4 cm, with complete liquefaction of the abscess and no separation. When the abscess is completely liquefied, the B-ultrasound shows the characteristics of complete cystic, thick wall, and turbid echo within the capsule.

Drainage can avoid important organs such as thoracic cavity, intra-abdominal gallbladder, and large blood vessels, especially those who cannot tolerate surgery in the elderly and infirm. Multiple liver abscesses are not contraindicated, and the boundaries between each abscess are clear and can be drained separately. If the pus is too thick, there are partitions in the abscess, the abscess cannot be punctured or the catheter is not drained smoothly, the effect is not good, or the abscess is ruptured or about to rupture, abscess incision and drainage should be performed.
