Introduction. Spinal anesthesia is one of the oldest and most commonly used
regional anesthesia techniques. It is based on the injection of a local
anesthetic into the subarachnoid space, during which there is a transient
interruption of impulse conduction in the spinal nerve roots. Application of
spinal anesthesia. The use of spinal anesthesia depends on the following
factors: the site of the surgical procedure, the type and duration of the
surgical procedure, the degree of necessary surgical relaxation, and
presence of accompanying diseases. Local anesthetics used in spinal
anesthesia. There are two types local anesthetics used in spinal anesthesia.
These are local anesthetics of the ester and amide type. Most frequently
applied local anesthetics are those of the amide type. Orthopedic procedures
under spinal anesthesia. The most common surgical procedures in orthopedic
surgery performed under spinal anesthesia are hip, knee and ankle surgeries.
Complications of spinal anesthesia. The most common complications of spinal
anesthesia are hypotension, bradycardia, urinary retention, and postpuncture
headache. Conclusion. The advantages of spinal over general anesthesia in
orthopedic surgery include lower incidence of respiratory and myocardial
depression, better peripheral tissue perfusion, minimal coagulation system
disorders and prolonged postoperative analgesia.
