After the opening of the uterus, forceps is an effective method of assisted labor compared with cesarean section, as it causes less damage, delivers the fetus faster, and provides quicker postoperative recovery. Compared with cesarean section, forceps does not use negative pressure, and the edema of the fetal head is small; fetal head attraction requires that the fetus is exposed at the exit of the pelvis, and forceps can pull the fetal head in a higher position. All three methods have their advantages and disadvantages, and the obstetrician will decide according to the different conditions of each woman. It is a misconception that forceps can damage the fetus. As long as the timing and conditions of the operation are appropriate, it will not cause irreversible damage to the newborn. I. Indications for surgery 1, contraction weakness, prolongation of the second stage of labor; 2, suffering from heart disease, tuberculosis, pre-eclampsia, etc. should not be overly forceful in labor; 3, placenta praevia, placental abruption, umbilical cord prolapse and intrauterine distress; 4, preterm infants protective perineal circumcision, forceps; 5, cesarean section of the head of the fetus is difficult to deliver, the forceps can be used to assist. Surgical conditions 1, the cervix must be open, otherwise it is easy to cause birth canal tear; transient maternal tissue is soft, if necessary, in the uterine mouth near the full opening of the operation; 2, the child’s head must be “articulation”, the lower the position of the head, the more safe the operation; 3, fetal membranes are not ruptured, it should be artificially rupture the membranes before the operation; 4, it must be a live fetus, stillbirths can be The dead fetus can wait for spontaneous delivery. The forceps should be divided into left and right lobes, and the operation should be performed first to understand whether the forceps can fit well, and to distinguish the left and right lobes. The left hand holds the left lobe and inserts it into the left side of the woman’s vagina (the three-left method), and vice versa for the right lobe. The procedure is divided into several steps: placement of the forceps, closure, traction and removal of the forceps. After the delivery of the fetus and placenta, the cervix is routinely checked for lacerations with the oval forceps, and then the perineal wound is sutured. Fourth, complications 1, maternal perineal injury, cervical laceration. It should be sutured according to the anatomical position, and if the wound of soft birth canal laceration is too large and difficult to be sutured by local anesthesia, it can be sutured under hard lumbar combined anesthesia. For severe perineal lacerations, after suturing the perineal wound, the vagina is filled with 4-5 blocks, which are removed in 4-6 hours. Retain the urinary catheter for 24 hours if necessary. 2.Newborn trauma: skin and mucous membrane injury, can be local symptomatic treatment, such as external application of Bactroban ointment or erythromycin ophthalmic ointment to prevent intracranial hemorrhage. V. Preventive principles 1, in order to prevent trauma caused by excessive force during traction, the operator should sit and traction, arms slightly bent, elbows next to the chest, slowly force. For those with insufficient arm strength, traction can be performed standing up, but the direction of force and traction should be well mastered. If the situation is urgent, the fetus should be delivered as quickly as possible, but never operate roughly. 3.Don’t fasten the two handles of forceps during traction, but put a small piece of gauze between the two handles to reduce the pressure on the fetal head. 4, in case of difficulty, should be detailed examination, discretionary reconsideration of the mode of delivery, do not force traction. Cesarean section should be performed if necessary. 5.Postoperatively, pay attention to the observation of contractions and bleeding, check the cervix and vagina, if there is a tear, immediately suture. 6.If the labor is long and there is hematuria in catheterization, the catheter can be left in place, and anti-infective drugs can be used as appropriate. 7.Check the newborn carefully, give hemostatic drugs to prevent intracranial hemorrhage, and prevent infection.
