Can ultrasonography help in reducing post spinal headache?

Abstract

The advent of ultrasonography (USG) did not remain restricted to diagnostic radiology only, and during
the last one decade it has wholeheartedly been adopted by anesthesiologists. First employed for central
venous access only, it soon trespassed into the domains of peripheral nerve and nerve plexus blocks, and
now made inroads in general as well as central neuraxial anesthesia. In this editorial three techniques
used for USG guidance in regional anesthesia have been introduced and special groups of patients have
been indicated in which it may particularly be useful. Its positive role to detect abnormal sonoanatomy
and decrease the incidence of postdural puncture headache following intentional or unintentional dural
puncture has been discussed.
