The effect of transverse abdominal fascia block

With the development of society, people's living standards have improved, and they have better food and clothing, but people are suffering from more and more diseases. We are not unfamiliar with the name of transverse abdominal fascia block, especially those who have gone to the hospital for surgery. Transverse abdominal fascia block plays an analgesic role during surgery. Some patients have side effects on anti-inflammatory drugs or analgesics, and transverse abdominal fascia block fills this gap.

Transverse abdominis plane block for postoperative analgesia in abdominal surgery.

The degree of pain during abdominal surgery is closely related to the surgical method, scope of surgery, type of surgery, etc., and varies from person to person. Postoperative pain mainly comes from the abdominal incision. Therefore, blocking pain transmission from this source can greatly reduce postoperative pain.

Currently, there are various methods for postoperative analgesia in abdominal surgery, among which opioids are the main drugs with a wide range of applications. However, whether opioids are used for general anesthesia or intrathecal administration, they can produce a series of side effects, such as nausea, vomiting, itching, intestinal obstruction, urinary retention, constipation, and even respiratory depression, which are dose-related.

The transverse abdominal plane block technique is to inject local anesthetic into TAP to block the sensory nerves passing through this plane, thereby achieving analgesic effect. In-depth medical research has confirmed that TAP block technology can be used well for postoperative analgesia after abdominal surgery, greatly reducing the dosage of opioids, and then reducing opioid-related side effects, making patients more satisfied with the overall analgesic effect and making postoperative analgesia safer.

Complications and contraindications of TAP block The incidence of complications of TAP block is extremely low, including: infection, hematoma formation, nerve damage, toxic reaction of local anesthetics (excessive dose of local anesthetics or accidental injection into blood vessels), penetration of the abdominal cavity, intestinal perforation, liver perforation, etc. In one case, the liver was accidentally punctured, but it was later discovered that the patient's liver was already pathologically enlarged (to the iliac crest), and they used the "blind puncture method." Lancaster and Chadwick[2l also reported a case of accidental liver puncture. Although the puncture was performed under ultrasound guidance, the operator did not determine the position of the puncture needle before puncturing. Absolute contraindications to TAP block include patient refusal, abdominal skin and soft tissue infection, and abnormalities of the puncture site. Whether coagulation dysfunction is an absolute contraindication requires further study.
