saddle block anaesthesia
Noun: A specific type of regional anesthesia, also known as saddle block, used primarily for procedures involving the perineum, rectum, or inner thighs. It is achieved by injecting a local anesthetic into the cerebrospinal fluid in the lower spinal canal, numbing only the areas of the body that would contact a saddle if sitting on a horse (the "saddle area").
This term is used in a medical context to describe an anesthetic technique. - It is administered for surgeries such as hemorrhoidectomies, vaginal deliveries, or cystoscopies. - The patient typically remains sitting upright for a short period after the injection to allow the dense anesthetic solution to settle and affect only the lowest spinal nerves.
- The technique is a form of spinal anesthesia but is distinguished by its very limited and specific area of effect.
- It is sometimes preferred for brief outpatient procedures due to its rapid onset and the patient's ability to recover lower limb strength relatively quickly compared to a full spinal block.
- Saddle block anesthesia (US English spelling, without the 'ae' ligature).
- Saddle block (common abbreviated form).
- Caudal anesthesia: A related regional technique involving injection near the tailbone (coccyx), which can also anesthetize the saddle area.
- Saddle block
- Perineal anesthesia (descriptive synonym focusing on the area affected)
This is a highly specialized medical term. The key conceptual component is the targeted numbness of the specific "saddle" distribution of nerves. It is not a general term for any spinal anesthesia.
- the parts of a patient's body that would touch a saddle if the patient were sitting in one are anesthetized by injecting a local anesthetic into the spinal cord
