Can ultrasonography help in reducing post spinal headache?

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.
