(2) Insertion and Application
① Using aseptic technique, remove the catheter from the package.
② Perform vaginal exam to insure ruptured membranes and adequate dilation.
③ Advance the catheter tip to the cervical os along the examination hand, using the
hand as a guide. Do not advance the introducer through the cervix.
④ Continue to gently advance the catheter tip through the cervical os and feed the
catheter into the intra-amniotic cavity until the 45cm mark is at the introitus. If the
45cm mark is not clearly visible, stop advancing when the Saflex™ logo on the
catheter meets the end of the introducer.
⑤ Remove the introducer by carefully sliding it back out of the vagina along the
catheter. When the introducer is completely out of the vagina, twist it away from the
catheter beginning at the proximal end. Peel the introducer away from the patient
(See Figure 5-4).
