Spinal Anesthesia: It’s Uses And Benefits

By ChemistsWorld On 18 Sep 2018

Spinal Anesthesia, or better called as sub-arachnoid anesthesia is a form of regional or local anesthesia, which involves an injection of a local anesthetic drug into an individual’s sub-arachnoid cerebrospinal fluid space (CFS).

What is the use of Spinal Anesthesia?

Spinal anesthesia has the benefit of rapid onset of action, simplicity, low failure rate, excellent muscle relaxation, and minimum drug dose which makes it the technique of choice for both emergency and elective cesarean section when a functional epidural catheter is not in its place. Therefore, it is used for:

  • Cesarean surgeries.
  • Surgeries that are below the umbilicus such as the genitourinary surgery, surgeries performed on the lower extremities (lower limbs) or hernial repair procedures.

How does it work?

Spinal anesthesia provides comprehensive and rapid anesthesia for cesarean or surgery section by reversibly blocking the nerves in the spinal canal serving both deep and superficial tissues. In doing so, the pain transmission is not delivered to your brain, thus decreasing the brain’s awareness of the pain during the procedures and provides pain relieve to the medical patient.

If spinal anesthesia is used at the time of childbirth, a midwife or trained medical staff must be always present for at least 15-20 minutes after each bolus dose in order to record the maternal blood pressure, pulse and the fetal heart in every 5 minutes and assess the height of the block. Alternatively, if spinal anesthesia is used at the time of the surgeries, the same protocols of close monitoring of pulse, respiration, and blood pressure should be followed.

What kind of diseases are treated with Spinal Anesthesia?

  • Pain during childbirth or cesarean surgeries.
  • Surgeries below the umbilicus such as the hernial repair procedures, or surgeries performed on the lower extremities (lower side of the limbs).
