We have found also that there is typically a much greater need for downward traction initially before then turning outward and upward to take the fetus into flexion for delivery. For OP presentations, the biparietal diameter is typically much higher than anticipated and Dennen recommends depressing the shanks against the perineum before locking (effectively inching them higher and more anterior on the parietal bone). Learn all about the factors affecting labor, fetal position, and fetal station.Our Maternity Nursing video tutorial series is taught by Meris Shuwarger, BSN. Only after the occiput clears the symphysis is this then transitioned to outward then upward to minimize perineal injury. For an OA presentation, this requires direct downward (axis) traction. Last, the correct direction of traction is best achieved by visualizing the presenting part and cardinal movements necessary for delivery. This is easily resolved by moving the left handle so that it falls under the right and the English lock will come together correctly. These 7 mechanisms of labor occur in normal labor which is a normal lie, presentation, and attitude. This is when the whole body of the baby is born. If, however, the right blade was placed first (as would be the case in a ROA or LOP presentation placing the posterior blade first), then they will appear to come together and be unable to lock. At the same time, the anterior shoulder of the baby passes through the pubic arch, and then the posterior shoulder will pass through the pelvic canal. during labor utkarshnursingclasses UTKARSHCLASSESJODHPUR Utk. A forceps blade on the correct trajectory should require almost no force, and I remind learners of this by encouraging them to hold the handle with only their fingertips.Īs the forceps lock, if the left blade was placed first, this allows the English lock to come together easily. CARDINAL MOVEMENT OF LABOR //10 CARDINAL MOVEMENT10cardinal movements of laborfetal movement. Doing so starts the blade of the forceps down the sacrum/face (in an OA fetus) rather than along the more hollow space between parietal bone and vagina. Importantly, as the forceps begins its motion, there can be no movement forward or backward of the handle until the maternal thigh is reached. It is important that the cephalic curve (or “palm side” of the blade) is as closely apposed to the fetal scalp as possible, or if the fetal scalp is not visible, then to the maternal introitus. In a study of 496 single pregnancies in labor at term, digital examination failed to detect the fetal head position in 166 cases (33. The most frequent struggles are usually encountered in initial placement – particularly of the second blade – and less commonly during traction. Regarding cardinal movement, ultrasound examination may provide more accurate information about fetal position than digital examination.
