  Spinal Anesthesia
Spinal anesthesia is a form of local anesthesia in which an injection of local anesthesia is made in the low middle part of your back.
Spinal anesthesia is a safe form of anesthesia.
Some possible complications of spinal anesthesia include spinal headache, low back ache after recovery from anesthesia, and failure to establish spinal anesthesia.

 Cesarean delivery   (Site not responding. Last check: 2007-10-08)
Spinals, epidurals and combined spinal-epidurals are regional anesthetics.  A section or "region" of the body is numbed by the medicine that is injected into the spinal canal.
The spinal cord and the nerves are contained in a sac of cerebrospinal fluid.  The space around this sac is the epidural space (see section on 'Regional anesthesia').  Spinal anesthesia involves the injection of numbing medicine directly into the fluid sac.  Epidurals involve the injection into the space outside the sac (epidural space).
The procedure for spinal anesthesia is similar to epidural anesthesia for labor or for cesarean delivery (see picture).  The difference is that medicine is injected directly into the spinal sac.  A thin needle is used to reduce the chances of a spinal headache.

 Nursing: Getting to the root of pain: Spinal anesthesia and analgesia   (Site not responding. Last check: 2007-10-08)
Spinal anesthetics and analgesics are administered into the subarachnoid (intrathecal) space at the time of surgery.
Spinal anesthesia is achieved by a single intrathecal injection of local anesthetic into the subarachnoid space to create sensory, motor, and autonomic blockage of the nerve roots and spinal cord.
Disadvantages to spinal anesthesia include the extra time and expertise needed to position the patient and insert the needle, and possible pain from needle placement and medication administration.

 Patients' Guide to Local and Regional Anaesthesia
Spinal anaesthesia is suitable for many procedures in the lower half of the body.
Spinal anaesthesia is especially useful during TURP surgery, as it allows the patient to detect side effects of the washing solution used in the bladder (it makes their vision fade temporarily) and it encourages clotting in the cut blood vessels.
The major disadvantage of a spinal anaesthetic is a drop in blood pressure, caused by temporary blockage of the nerves that control blood flow into the legs, so that blood collects in them.

The needle for Epidural passes between the vertebrae of the Spinal column to the Epidural space.

Your anesthesia specialist, whether it is an anesthesiologist or a nurse anesthetist, is responsible for your comfort and safety during your surgery.
Anesthesia is used to relax (sedate) you, block pain sensations (analgesia and anesthesia), induce sleepiness or forgetfulness (amnesia), or make you unconscious for your surgery.
A local anesthetic is injected near the spinal cord and nerves that connect to the spinal cord to block pain from an entire region of the body, such as the abdomen, hips, or legs.

If a spinal anaesthetic and the ensuing surgery are performed skilfully, the majority of patients are very happy with the technique and appreciate the rapid recovery and absence of side effects.
Spinal anaesthesia is particularly suitable for older patients and those with systemic disease such as chronic respiratory disease, hepatic, renal and endocrine disorders such as diabetes.
In the event of an inadequate spinal anaesthetic it is much better to electively administer a light general anaesthetic and safeguard the airway, then to over-sedate a patient with benzodiazepines or narcotics.

 Spinal Anesthesia in the Post-delivery Period
In a patient with cardiovascular disease in whom a relatively high block to T4 is risky (Chapter 83), a lower level is acceptable and anesthesia is supplemented by intraperitoneal instillation of 80 ml of 0.5% lidocaine 5 minutes earlier (3).
The local anesthetic requirement for each spinal segment block after spinal anesthesia is less in cesarean section than in gynecologic operation, the ratio being 1:1.5.

Spinal anesthesia involves the injection of a small amount of local anesthetic directly into the cerebrospinal fluid surrounding the spinal cord (the subarachnoid space).

A recent study from Massachusetts General Hospital shows that spinal anesthesia may be superior to general anesthesia for oocyte, or egg, retrieval in terms of pregnancy rates as well as patient satisfaction.
While both groups reported high levels of satisfaction rates with their anesthesia, the patients choosing spinal anesthesia all said that they would repeat that choice in the future.
The authors of the study commented that spinal anesthesia was associated with fewer side effects, whereas general anesthesia can cause prolonged sleepiness, nausea, and/or vomiting after the operation.

 Spinal Headache Prevention
But, if spinal fluid leaks out through a needle hole, the pressures become imbalanced, and the cushioning effect of the fluid disappears and tension is applied directly to these nerves.
Previous "conventional wisdom" in preventing or alleviating spinal headache has generally gone along three lines: (1) Use a smaller or higher-tech needle, make a smaller hole, and less fluid will leak out, so headache will be milder or less prevalent.
The "few percentage points" may be of comfort the to patient before anesthesia, but is no comfort afterwards if he or she is one of the hundreds of thousands who have fallen into that "few percent".

An association between the occurrence of RLS and spinal anesthesia has been described, but little is known about this apparent relationship.
This study examines the possible relationship between RLS and spinal anesthesia and assesses the incidence and time course of new onset RLS in 202 patients undergoing spinal anesthesia for a variety of surgical procedures.
The occurrence of new-onset RLS after spinal anesthesia was associated with low mean corpuscular volume and mean corpuscular hemoglobin, suggesting that iron deficiency may influence susceptibility.
