Paraesthesia during the needle-through-needle and the double segment technique for combined spinal epidural anaesthesia . Paraesthesia during regional anaesthesia is an unpleasant sensation for patients and , more importantly , in some cases it is related to neurological injury . Relatively few studies have been conducted on the frequency of paraesthesia during combined spinal epidural anaesthesia . We compared two combined spinal epidural anaesthesia techniques : the needle-through-needle technique and the double segment technique in this respect . We randomly allocated 116 parturients undergoing elective Caesarean section to receive anaesthesia using one of these techniques . Both techniques were performed using a 27G pencil point needle , an 18G Tuohy needle , and a 20G multiport epidural catheter from the same manufacturer . The overall frequency of paraesthesia was higher in the needle-through-needle technique group ( 56.9 % vs. 31.6 % , p = 0.011 ) . The frequency of paraesthesia at spinal needle insertion was 20.7 % in the needle-through-needle technique group and 8.8 % in the double segment technique group ; whereas the frequency of paraesthesia at epidural catheter insertion was 46.6 % in the needle-through-needle technique group and 24.6 % in the double segment technique group .
