A syringe adapter to facilitate aspiration at amniocentesis

Obstetrics and Gynecology
J N RobinsonE R Norwitz


Syringes were developed for injection, not aspiration. We describe an adapter that attaches to a standard syringe and aspirates by advancement rather than withdrawal. The adapter consists of a syringe barrel extension and an attachable finger grip. The adapter attached to a standard syringe allows aspiration by advancement rather than withdrawal, with the same hand motion used as with injection. In a comparison of timed in vitro fluid aspiration by 10 practitioners, mean times for aspiration of 15 mL were 32.4 seconds (range 24-45) with standard technique and 25.3 seconds (range 24-30) with the adapted syringe (P < .003, paired t test). Thirteen of 14 physicians who used the adapted syringe in vivo reported that much less effort was required, and one physician reported that a little less effort was required. Overall, eight practitioners reported that the adapted syringe made amniocentesis much easier and six found no difference between the two devices. This adapter converts a standard syringe to one permitting aspiration by advancement rather than withdrawal. Practitioner feedback was positive with regard to ease of use, degree of effort, and overall satisfaction.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Hereditary Sensory Autonomic Neuropathy

Hereditary Sensory Autonomic Neuropathies are a group of inherited neurodegenerative disorders characterized clinically by loss of sensation and autonomic dysfunction. Here is the latest research on these neuropathies.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Landau-Kleffner Syndrome

Landau Kleffner syndrome (LKS), also called infantile acquired aphasia, acquired epileptic aphasia, or aphasia with convulsive disorder, is a rare childhood neurological syndrome characterized by the sudden or gradual development of aphasia (the inability to understand or express language) and an abnormal electroencephalogram. Discover the latest research on LKS here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.


Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.

Regulation of Vocal-Motor Plasticity

Dopaminergic projections to the basal ganglia and nucleus accumbens shape the learning and plasticity of motivated behaviors across species including the regulation of vocal-motor plasticity and performance in songbirds. Discover the latest research on the regulation of vocal-motor plasticity here.
