Where is the anesthesia for gastrectomy

Generally, the method of single spinal anesthesia (often referred to as "half anesthesia") is rarely used for gastrectomy. Generally, general anesthesia is usually used. Of course, general anesthesia combined with spinal anesthesia is also used. . If half anesthesia is used, it is mostly combined spinal and epidural anesthesia.

Combined spinal-epidural anesthesia uses the characteristics of spinal anesthesia and epidural anesthesia to improve the anesthesia effect and increase the technical level of operation. It carries forward the advantages and strengths of the two, and makes up for the shortcomings and deficiencies of the two.

Advantages and benefits of combined epidural anesthesia:

Rapid onset of action; exact effect; unlimited anesthesia time; small amount of local anesthetic; low incidence of local anesthetic poisoning; postoperative epidural analgesia; true spinal anesthesia "non-contact" technique.

Steps:

1. Put the patient in the same position as spinal anesthesia

2. Take L2-3 or L3-4 for the puncture point.

3. Puncture method

Aseptic operation requires the same as spinal anesthesia or epidural block. After successful epidural puncture, a 25G lumbar puncture needle was inserted into the needle with the epidural needle as the guide, passed through the epidural needle port, punctured the arachnoid, and withdrawn from the needle core, and the cerebrospinal fluid was seen flowing out of the needle. Randomly inject 2-3ml of local anesthetic for spinal anesthesia, withdraw from the lumbar puncture needle, insert an epidural catheter through the epidural needle (3cm through the needle port), withdraw from the epidural puncture needle, cover the puncture point with sterile gauze, and fix the catheter . After helping the patient to turn over to lie on his back, measure the level of spinal anesthesia block. Inject 3-5ml of local anesthetic through the epidural catheter. After 5 minutes, there is no sign of high block level, and the operation can be started. During the operation, an appropriate amount of local anesthesia was injected through the epidural catheter as needed to maintain anesthesia.
