Background and Objectives. This prospective, randomized, double-blind study
compares the efficacy of two spinal needles in terms of their performance
characteristics and associated perioperative complaints in young patients.
Methods. ASA I and II patients aged from 20 to 40 years undergoing lower li
mb orthopedic surgery were included during a 12-month period. After applica
tion of the protocol, 158 patients were recruited. The patients were random
ized to two groups: group I: 26-gauge Atraucan (n = 79) and Group II: 27-ga
uge Whitacre (n = 79). A study was made of the demographic parameters, tech
nical characteristics, and peri- and postoperative complications. Results.
No significant differences were found in the technical handling of the need
les, number of attempts made to achieve the puncture, or the time required
to perform the technique. No technical failures (spinal anesthesia inadequa
te for the planned surgery) were reported, and the frequency of complicatio
ns during the procedure was identical in both groups. Frequency of postdura
l puncture headache (3.8%) or severity and duration showed no difference be
tween the two groups. The overall assessment of postoperative complications
revealed similar scores for both needles. Conclusions. Technical handling
(ease with which block was performed) of the needles analyzed was extremely
easy, showing a high success rate which associated with the similar incide
nce of complications. Type of bevel does not appear to be a determining fac
tor in the quality or morbidity associated with subarachnoid block when fin
e-gauge needles are used in young patients.
