He will insert a needle between the bones in your lower spine and inject anesthesia medicine. Tell your caregiver if you feel a tingling shock or pain in your leg.
You will be awake during surgery but may be given medicine in your IV to make you sleepy. Depending on your surgery or procedure, you will be taken to your hospital room or sent home.
If you were given medicine to make you sleepy, have someone stay with you for 24 hours after your procedure. Discuss treatment options with your caregivers to decide what care you want to receive.

Other features, such as the rapid onset, dense block, early patient mobilization, and a short hospital stay, have made spinal saddle anesthetic block the procedure of choice for personal surgeries, particularly in high-volume, day surgery centers. It extends downwards to terminate at the level of first (L1) in adults or second (L2) lumbar vertebra in infants where it tapers to form the bonus medullas.
Three layers of meninges surround the spinal cord, including aura, arachnid, and Pia mater. The subarachnoid space is present between the arachnid and Pia mater and contains the cerebrospinal fluid, the site for injection of various anesthetic drugs.
Constant monitoring of the mentioned parameters is imperative during the intraoperative period at regular intervals; usually, every 5 minutes. This fact renders loading a patient with a Lopressor such as phenylephrine before starting the procedure useless.
Keeping the patient in the sitting position, establish a sterile field using an appropriate antibacterial solution. Identifying the correct space for injecting the agent is a crucial step, not only to obtain the desired level of anesthesia but also to avoid trauma to the tail end of the cord, i.e., the bonus medullas.
A hypodermic needle is then inserted into the skin in the midline to obtain analgesia between the third and fourth lumbar vertebral spines. A spinal needle (gauge 22 to 25) of choice is then introduced in the midline at the level of said interspace with a 15 degree cephalad angulation with the patient in sitting position.
As it courses deeper into the supraspinatus and interspinous ligaments, the practitioner will feel an increase in tissue resistance. The first is due to the penetration of ligamentum flavor, which has its maximal thickness in the lumbar region, ranging about 2 to 5 cm.
Confirm the successful rural puncture by withdrawing the style and observing spontaneous clear cerebrospinal fluid (CSF) leakage through the needle. With a small gauge (25G) needle, it might be necessary to aspirate the CSF to confirm its placement in the subarachnoid space.
The patient is instructed to keep sitting in the same position for three to ten minutes after the injection of the drug. This slight modification of the technique is how to obtain low spinal anesthesia in the literal sense of the term.
Assess the hematoma level of sensory block by temperature sensation (cold) using an alcohol swab or a pinprick test bilaterally. Even though induction with saddle block anesthesia is relatively safe, simple, and easier to perform, it has certain disadvantages.
The patient is recommended to keep sitting for a longer duration of time after administering the drugs, which can cause postoperative urinary retention to be more often with the saddle block. This complication is reducible by changing the patient to a jack-knife position after maintaining the initial sitting posture for only one minute.
Also, the time delay in the induction of anesthesia poses a nuisance in the initiation of surgical procedures. This effect can be countered by simultaneous intrathecal administration of various adjuvants (e.g., opioids like fentanyl, clonidine and dexmedetomidine).
Use of such adjuvants potentiate analgesia and facilitate reductions in the required dose of local anesthetic. Complications possible to arise at the hands of inexperienced anesthesiologists include neural injury, nerve root (peripheral neuropathy) or spinal cord damage (paraplegia), and caudal equine syndrome (numbness around the anus, back pain radiating down the leg, loss of bowel or bladder control).
Spinal techniques are always preferred over general anesthesia since these procedures prevent the need for tracheal intubation that leads to airway irritation and numerous respiratory complications. The major complication encountered with the subarachnoid block is hypotension attributable to the chemical sympathectomy.
It becomes more complicated when coupled with circulatory overload in the elderly and patients with an already compromised cardiopulmonary function. The circulatory overload results from the intravenous fluids and vasopressors administered in the interest of correcting the hypotension.
Early postoperative mobilization observed with this technique is a gratifying feature that accounts for its increased popularity for the use in out-patient surgeries. The method is most worthy of use in obstetrics as it benefits the fetus in spontaneous respiration with no increase in fetal and maternal morbidity or mortality.
The use of ultrasound would allow for better identification of landmarks and the midline, estimation of the depth of ligamentum flavor, and the angle of insertion for the needle. Ultrasonography as the standard care for this procedure is bound to have positive effects on patient, surgeon, and anesthesiologist satisfaction.
It would benefit by reducing the number of needle redirections, reinsertion, traumatic taps, failed attempts, and overall the adverse outcomes. Implementation of checklists and guidelines reduces surgeon-anesthesiologist miscommunication, and so has proven to decrease the adverse outcomes.

However, we have not included the patient in this series for the reason that we are unable to substantiate the diagnosis of chronic adhesive arachnoiditis from the findings made available to us. In any event, we strongly suspect that this patient represents another case of a serious complication from spinal anesthesia used for obstetrical delivery.

Adrian and Roman-Vega, 1 in 1946, suggested the term saddle block to describe a technique of spinal anesthesia which provides analgesia limited to the saddle area. In essence, this technique is a conduction block of the lower lumbar and sacral segments of the spinal cord by an anesthetic agent dissolved in glucose to produce a hypertonic solution.
However, this procedure requires the introduction of an anesthetic agent into the subarachnoid space, thus exposing the patient to the complications associated with any form of spinal anesthesia. It is the purpose of this paper to bring to the attention of physicians (obstetricians and anesthetists in particular) a delayed complication resulting from this type of anesthesia in normal obstetrical deliveries.
