How to do pelvic internal examination

Pelvic examination is usually performed in the late pregnancy. This is because the specific condition of the pelvis determines the way the pregnant woman becomes pregnant. Generally speaking, if the pelvis is normal, the pregnant woman can give birth through natural delivery. Of course, if the pelvis is not in the correct position or is too narrow, cesarean section is the only option. So, how to check the pelvic internal examination? The following will give a detailed introduction!

Pelvic examination usually involves the doctor wearing rubber gloves, disinfecting the vulva first, and then inserting his hand into the vagina for examination. The purpose of pelvic examination is to determine whether the pregnant woman can give birth naturally. There may be some pain during the examination. The pregnant woman must relax her whole body when the doctor inserts his hand into the vagina. The examination time is very short, and as long as the whole body is relaxed, it generally will not hurt.

When measuring the pelvis, usually the external pelvic measurement is performed first, that is, the normal value of the anterior superior iliac spine diameter is 23-26 cm, the normal value of the iliac crest diameter is 25-28 cm, the sacropubic external diameter is greater than 18.5 cm, the normal value of the greater trochanter diameter is 28-31 cm, the normal value of the ischial tuberosity diameter is 8.5-10 cm, and the pubic arch angle is greater than or equal to 90 degrees. If any or all of the external pelvic diameters are abnormal, internal pelvic measurements should be performed during labor, and a normal delivery method should be chosen based on fetal size, fetal position, and labor force.

The person being examined takes off their underwear, lies on the examination bed, and straddles the footrests on both sides. Once in position, the doctor will first observe whether there is any abnormality in the vulva, then use a speculum to open the vagina and observe whether there is inflammation or erosion of the vaginal wall and cervix. If necessary, a cervical smear or secretion sample may be taken for examination, or suppositories or ointments may be administered for treatment. After taking out the speculum, the doctor will insert the index finger (or two fingers) into the vagina to lift up the uterus; with the other hand, the doctor will touch and press the lower abdomen to determine the position, size and hardness of the uterus, and whether there is tenderness, thickening or swelling in the bilateral adnexal areas.

A considerate doctor can still make internal examinations easier. You will be asked clear questions before the examination; during the examination, you will be told to take a deep breath, exhale slowly, and relax your stomach to facilitate the insertion of the speculum and palpation; you will be told at any time what you are doing, why you are doing it, etc. Generally speaking, the entire internal examination process usually does not exceed two or three minutes. Some patients are afraid that the cervical smear will be painful. In fact, the pain in the cervix is ​​not obvious. It is very simple to brush out the exfoliated cells from the cervix and it is not painful. Often, the doctor has done it and the patient does not even notice it.

In fact, the more relaxed you are during an internal examination, the less painful it will be. Therefore, women should relax, take deep breaths, cooperate with doctors, and never push down with their legs or lift their hips too high. This will not be conducive to the examination and will make the examination difficult, prolong the examination time, and cause pain.
