Amniovacucentesis vs standard syringe technique for amniocentesis: experience with 1219 cases

Am J Obstet Gynecol. 2009 Dec;201(6):593.e1-3. doi: 10.1016/j.ajog.2009.06.023. Epub 2009 Aug 7.


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.
