Is There An Effect On The Development Of Postdural Puncture Headache Of Dural Punction Made With The Spinal Needle In Three Different Orientations During Spinal Anaesthesia Applied To Pregnant Patients?

BACKGROUND AND

objectivesPostdural punction headache (PDPH) is a well-known and common complication of spinal anesthesia. The relationship between spinal needle size, configuration and perforation characteristics of the spinal needle and non-essential leak continues to be controversial.

methodsThis prospective-randomized study included 300 patients aged 18-45 years who underwent cesarean section under spinal anesthesia. Spinal anesthesia was performed using a 26G Quincke spinal needle in the L3-4, or L4-5 range in the sitting position. Spinal anesthesia was performed with spinal needle sharp tip opening in the Group 1 patients, right or left laterally in Group 2 and caudal in Group 3, transducing the dural fibers transversely to the subarachnoid area, and directing the free opening of the needle to the spine. The patients were visited in the clinic where they were hospitalized at the 24th and 48th hours postoperatively, and phoned on the 3rd and 5th days after discharge, being questioned for PDPH.

resultsIt was observed that 64% of patients with PDPH developed within the first 24 hrs, 24% between 24 and 48 hrs and 48-72 hrs in 12%. The incidence of PDPH was 14% in Group 1, 8% in Group 2 and 3% in Group 3. This difference between the groups was statistically significant (p: 0.019). The incidence of PDPH was lower in Group 3 than in Group 1 and Group 2.

conclusionWe suggest that when spinal anesthesia is applied in the obstetric patient group if needle opening faces caudal this method will reduce the frequency of PDPH.
