WHAT ARE THE COMPLICATIONS OF SPINAL ANESTHESIA?
Before proposing a patient spinal
anesthesia, an anesthesiologist not only must be alert of the indications and
contraindications of spinal anesthesia but also must be able to weigh the risks
and benefits of carrying out the procedure.
Complications of spinal blockade are often separated
into major and minor difficulties. Reassuringly, most main complications are
rare. Minor problems, however, are common and therefore must not be dismissed. Slight
complications include nausea, vomiting, mild hypotension, shivering, itch,
hearing impairment, and urinary retention. PDPH and failed spinal blockade are noteworthy,
and not uncommon, complications of spinal anesthesia. We therefore reflect them
as moderate complications. Failure of spinal anesthesia has been mentioned as
between 1% and 17% .
