title: Jet injection--local anesthesia for fitting and removal of IUDs.
abstract: Women with small uterine cavities and narrow cervical canals in particular suffer from symptoms such as discomfort, pain, cramps, bradycardia, syncope, and epileptoid convulsions during IUD insertions.  These problems can be avoided by paracervical block (PCB) with syringe and needle, which may, in rare cases, entail hazardous side effects.  These can be eliminated by the use of Jet Injection PCB.  The Jet Injector deposits a 2% or 3% anesthetic solution paracervically submucously under high carbon dioxide pressure.  The patient's fear of injection with a needle is avoided.  The method can be applied by paramedics since intravascular application of anesthetic solution is impossible.  The use of a more concentrated anesthetic solution allows dose reduction and the method of dispersion of the micro-drops ensures a more rapid onset.  Premedication is not required and disposable material is economized on.  This study is based on the application of Jet Injection PCB before insertion of medicated IUDs in 447 women; 60% nulligravidae, 14% nulliparous with abortion(s), 13% primiparae, and 13% multiparous.  Age ranged from 15-47 years.
