Objective:
To compare the short-term outcomes of two different-sized needles for genetic amniocentesis.
Materials And Methods:
A total of 271 amniocentesis were retrospectively evaluated in 2 groups concerning the size of the needles used during the procedure: Conventional 20-gauge (G) (n=164) and 22G (n=107). Periprocedural complications and cost-effectiveness were compared across the groups.
Results:
There were no differences between groups concerning complications within 15 days after the procedure (fetal loss, 0.6% versus 0.9%, and amniotic fluid leak 1.2% versus 1.8%, p=0.99 for each). The 22G needle was significantly more cost efficient (p<0.0001).
Conclusion:
The 22 G spinal needle is convenient for second trimester amniocentesis with similar complication rate and has a favorable cost profile.
