To reduce blood loss during laparoscopic gynecological procedures, including myomectomy and hysterectomy, surgeons often need to take the preventive measure of injecting a dilute vasopressor agent intramyometrial before they begin the procedure.
EzVu Visual Vasopressor Injector helps detect an inadvertent vascular puncture very early, even in a small calibre blood vessel, and with much more sensitivity than a conventional opaque needle.
EzVu is a 33-cm-long and 5-mm diameter hollow shaft providing a transparent terminal window at the distal end. On aspiration, the blood can be seen as soon as the needle punctures a blood vessel, at a volume as small as 0.03ml (less than a single drop of blood). The needle can then be withdrawn, flushed, and repositioned at a new site.
In laparoscopic surgery, the length of the needle used is 33 cm. If the surgeon were to puncture a blood vessel within the myoma and aspirate, the blood column would not rise high enough (i.e., 33 cm) to stain the fluid in the syringe red. Since most vessels in the myoma capsule are thin-walled venous channels, rather than arterial channels, the negative pressure caused by aspiration would temporarily empty the blood vessel and the total volume of blood aspirated into the injection needle would typically not be sufficient to create a blood column high enough to stain the fluid in the syringe red.
Severe Hypo or Hypertension
Severe peripheral vasopasm
Incorporating a small, transparent window within the needle shaft, close to the tip of the needle provides a higher probability of seeing blood in this window when the surgeon aspirates with the syringe. The needle can immediately be withdrawn and repositioned in the myometrium, remarkably reducing the chance of error and thereby increasing patient safety.
Detection of early inadvertent puncture
Detects inadvertent intravascular placement of injection needle before the solution is injected into the body
Minimizes blood loss
Vasopressor agent causes shrinkage of blood vessels which minimizes blood loss in laparoscopic gynecological procedures
Enhances Patient Safety
Increases patient safety during the intra myometrial injection of a vasopressor agent during myomectomy and reduces the incidence of catastrophic complications
