Objective: The aim of the study was to compare amniovacucentesis to the usual syringe use for amniotic fluid aspiration.
Study design: We compared 2 groups of procedures: 1117 amniocenteses performed with the usual syringe technique and 1219 amniovacucenteses.
Results: The numbers of needle insertions, unsuccessful amniocyte cultures, and miscarriage up to 21 days after the procedure were statistically not significant (P>.01) comparing the 2 techniques.
Conclusion: The vacuum tube serves as an automated aspiration tool alternative. The major subjective differences between the 2 methods are the operator's comfort and dexterity during sampling and the absence of an extra manipulation of the amniotic fluid after aspiration.
