Meaning and Definition
A medical procedure involving the injection of anesthetic into the cerebrospinal fluid in the lower spine to numb the lower body, often for surgery.
A specific type of regional anesthesia that blocks nerve impulses from the lower spinal segments, resulting in loss of sensation and motor function in the lower abdomen, pelvis, and legs, while the patient typically remains conscious.
Dialectal Variation
British vs American Usage
Differences
British English often uses 'anaesthesia' (with 'ae'), while American uses 'anesthesia'. The term 'spinal' is consistent. The synonymous term 'spinal block' is common in both.
Connotations
Technical/neutral in both. No significant connotative differences.
Frequency
Slightly higher frequency in American English due to broader common discussion of medical procedures in media. The British spelling 'spinal anaesthesia' is the standard form in UK medical texts.

FAQ
Frequently Asked Questions
No. While both involve the spine, a spinal injection goes into the cerebrospinal fluid for a faster, denser block. An epidural places medication outside this sac, often using a catheter for continuous pain relief.
You typically feel no pain (analgesia) and have loss of movement (paralysis) in the blocked areas, but you remain conscious and may feel pressure or movement.
A common temporary side effect is a headache caused by cerebrospinal fluid leakage. Low blood pressure and temporary difficulty urinating can also occur.
It depends on the drug used, but typically its effects last 1 to 4 hours, making it suitable for many common surgical procedures.
