This drug stops cells from growing, which ends the pregnancy. Association of pelvic inflammatory disease (PID) with ectopic pregnancy and preterm labor in Taiwan: A nationwide population-based retrospective cohort study. The diagnosis of threatened abortion should be made in patients with bleeding and an ultrasound-confirmed viable intrauterine pregnancy. If this decrease does not occur, the clinician should discuss with the patient whether she prefers to repeat the course of methotrexate or pursue surgical treatment. 2019;74. doi:10.6061/clinics/2019/e1111. In stable patients, close monitoring of symptoms, serial quantitative -hCG testing, and ultrasonography are recommended4 (Figure 28,10,14,15 ). Accessed Dec. 29, 2017. A history of ectopic pregnancies or a history of surgery on the fallopian tubes are the factors that most increase the risk. Women with an ectopic pregnancy may have irregular bleeding and pelvic or abdominal pain, often on one side. Typical hCG Doubling Times. The clinical manifestations and diagnosis of ectopic pregnancy are reviewed here with a focus on tubal pregnancy. If hCG levels have not decreased enough after the first dose, another dose of methotrexate may be recommended. Human chorionic gonadotropin (hCG) is a hormone normally produced by the placenta. Journal of Womens Health. These medications can affect the way methotrexate works in the body. Sound waves from the transducer create images of the uterus, ovaries and fallopian tubes. A speculum examination can help identify nonobstetric causes of bleeding, such as vaginitis, cervicitis, or a cervical polyp. These may include pain, fatigue, bleeding, and infection. Human chorionic gonadotropin (hCG) is a glycoprotein hormone composed of 2 dissimilar subunits, alpha and beta, joined non-covalently. After this . Ultrasound Exam: A test in which sound waves are used to examine internal structures. Implantation and placental development. Fallopian Tube: Tube through which an egg travels from the ovary to the uterus. If you are a Mayo Clinic patient, this could A pelvic exam can help your doctor identify areas of pain, tenderness, or a mass in the fallopian tube or ovary. Uterine aspiration is the preferred procedure for surgical management of early pregnancy loss. The discriminatory level (1,500 to 3,000 mIU per mL) is the -hCG level above which an intrauterine pregnancy should be visible on transvaginal ultrasonography. The medication is given by injection. Rho(D) immune globulin can also be administered within 72 hours of early pregnancy loss, especially later in the first trimester, although the risk of alloimmunization is estimated to be 1.5% to 2% in this setting.12 There is insufficient evidence for or against the use of Rho(D) immune globulin in Rh-negative patients who present with threatened abortion. An ectopic pregnancy is when a fertilized ovum implants outside of the uterus. Patients should be counseled to avoid taking folic acid supplements and nonsteroidal anti-inflammatory drugs, which can decrease the effectiveness of methotrexate, and to avoid anything that may mask the symptoms of ruptured ectopic pregnancy (e.g., narcotic analgesics, alcohol) and activities that increase the risk of rupture (e.g., vaginal intercourse, vigorous exercise). Advanced ectopic pregnancy (high -hCG level, large mass, embryonic cardiac activity) Copyright 2023 American Academy of Family Physicians. hCG levels at 6 weeks: 1,080-56,500 mIU/ml hCG levels at 7-8 weeks: 7,650-229,000 mIU/ml hCG levels at 9-12 weeks: 25,700-288,000 mIU/ml hCG levels at 13-16 weeks: 13,300-254,000 mIU/ml hCG levels at 17-24 weeks: 4,060-165,400 mIU/ml hCG levels at 25-40 weeks: 3,640-117,000 mIU/ml hCG levels if not pregnant: 0-5 mIU/ml Despite the fact that these factors can increase a persons risk of an ectopic pregnancy, anyone can experience an ectopic pregnancy. In cases where methotrexate is contraindicated or not preferred by the patient, surgical management can usually be performed laparoscopically if the patient is hemodynamically stable. Methotrexate often is given by injection in one dose. All patients should be instructed to seek care if they have symptoms of anemia or heavy bleeding, quantified as soaking through more than two sanitary pads per hour for two consecutive hours.3. The female body normally has two fallopian tubes. Very early in pregnancy, the embryo can grow within the fallopian tube without causing any symptoms. Ectopic pregnancy occurs when a fertilized ovum implants outside of the uterine cavity. The first measurement helps the clinician decide between the one- and two-dose protocols. 1 While there have been rare, well-publicized cases where an ectopic pregnancy has been brought to term, pregnancies of this sort are almost universally considered nonviable. Blood tests and ultrasound testing can alert your doctor if another ectopic pregnancy is developing. Further evaluation is needed unless a definitive nonobstetric cause of bleeding is found or products of conception are seen (Figure 1).8, The subunit of human chorionic gonadotropin (-hCG) can be detected in the plasma of a pregnant woman as early as eight days after ovulation.9 Quantitative -hCG levels can provide useful information in early pregnancy. Methotrexate may be used if the pregnancy has not ruptured a fallopian tube. Ectopic pregnancy should be considered in any pregnant patient with vaginal bleeding or lower abdominal pain when intrauterine pregnancy has not yet been established (Table 2).10 Vaginal bleeding in women with ectopic pregnancy is due to the sloughing of decidual endometrium and can range from spotting to menstruation-equivalent levels.10 This endometrial decidual reaction occurs even with ectopic implantation, and the passage of a decidual cast may mimic the passage of pregnancy tissue. Next, your doctor uses a thin tube equipped with a camera lens and light (laparoscope) to view the tubal area. However, emergency medical help is needed if you develop these warning signs or symptoms of an ectopic pregnancy: Call 911 (or your local emergency number) or go to the hospital if you have the above symptoms.

Established criteria should be used to determine treatment options for ectopic pregnancy, including expectant management, medical management with methotrexate, or surgical intervention. Accessed Dec. 4, 2019. Patient satisfaction, mental health outcomes, infection rates, and future fertility are similar between these treatments.2022 Mental health outcomes are better when patients are included in the decision-making process, and shared decision making should guide management.23. An ectopic pregnancy is when the fertilized egg remains in the fallopian tube and continues to develop. Kelly Gleason describes the roller coaster of a miscarriage and ectopic pregnancy diagnosis, and the importance of shared decision making. Copyright 2019 by the American Academy of Family Physicians. Prescription pain medication and nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen. In Vitro Fertilization (IVF): A procedure in which an egg is removed from a womans ovary, fertilized in a laboratory with the mans sperm, and then transferred to the womans uterus to achieve a pregnancy. Vital signs indicating hemodynamic instability or peritoneal signs on physical examination require emergent evaluation. There are specific findings on an ultrasound that can show that the pregnancy is ectopic. Molecular Reproduction and Development. In an ectopic pregnancy, the fertilized egg implants somewhere other than the lining of the uterus. In a salpingectomy, the ectopic pregnancy and the tube are both removed. Ectopic pregnancy occurs when a fertilized ovum implants outside of the uterine cavity. Ectopic pregnancies happen when a fertilized egg implants somewhere outside of the uterus, like the fallopian tube or the cervix. For symptomatic women with a viable intrauterine pregnancy, initial -hCG levels of less than 1,500 mIU per mL, 1,500 to 3,000 mIU per mL, or more than 3,000 mIU per mL will increase over 48 hours by at least 49%, 40%, or 33%, respectively.10 A slower rate of increase suggests early pregnancy loss or ectopic pregnancy. The Diagnosis and Treatment of Ectopic Pregnancy. Endometriosis: A condition in which tissue that lines the uterus is found outside of the uterus, usually on the ovaries, fallopian tubes, and other pelvic structures. McGraw-Hill Education; 2018. https://accessmedicine.mhmedical.com. An intra-uterine pregnancy can usually be seen by 5-6 weeks gestation or when the HCG level is more than 1000 IU/l. The initial -hCG level should be considered when following the rate of -hCG increase in early pregnancy. Methotrexate can cause sun sensitivity.

An hCG level of less than 5 mIU/mL is considered negative for pregnancy, and anything above 25 mIU/mL is considered positive for pregnancy. Higher-than-typical hCG levels can signal that you're carrying multiples or, in rare cases, have a molar pregnancy. Many regimens for using misoprostol alone have been studied, and none has been proven optimal.22 One common regimen is 800 mcg vaginally, with a repeat dose in 24 to 48 hours if the first dose is unsuccessful.27 Besides the expected cramping and vaginal bleeding, common adverse effects include nausea and diarrhea.22. 2019;14(8):e0219351. It uses sound waves to create images of your uterus, ovaries and fallopian tubes, and sends the pictures to a nearby monitor. However, there are some very rare medical conditions that can cause high hCG levels. Severe abdominal or pelvic pain accompanied by vaginal bleeding. The behavior of this hormone can help detect a dangerously abnormal pregnancy. Serial beta human chorionic gonadotropin levels, serial ultrasonography, and, at times, uterine aspiration can be used to arrive at a definitive diagnosis. In fact, a 2017 study into hCG found that "the slowest or minimal rise for a normal viable intrauterine pregnancy was 24% at one day and 53% at two days. A hCG level that is rising by less than 66% over 48 hours when the hCG is below 1,200 IU means it is likely, but not a certainty, that the pregnancy is ectopic. Other side effects may include: It is important to follow up with your ob-gyn or other health care professional until your treatment with methotrexate is complete. https://www.aafp.org/pubs/afp/issues/2020/0515/p599.html.

Symptoms may include the following: Sudden, severe pain in the abdomen or pelvis. Before you take methotrexate, blood tests will be done to measure the level of hCG and the functions of certain organs. PloS One. The discriminatory level is the -hCG level above which an intrauterine pregnancy is expected to be seen on transvaginal ultrasonography.14 When combined with -hCG levels greater than the discriminatory level, ultrasonography that does not show an intrauterine pregnancy should raise concern for early pregnancy loss or ectopic pregnancy. A meta-analysis evaluating the accuracy of a single progesterone test to predict pregnancy outcomes for women with first trimester bleeding showed that a progesterone level less than 6 ng per mL (19.1 nmol per L) reliably excluded viable pregnancy, with a negative predictive value of 99%. Expert opinion and consensus guideline in the absence of clinical trials, Verify baseline stability of complete blood count and comprehensive metabolic panel; determine -hCG level. All women who may conceive should be counseled to take folic acid. For trusted, in-depth advice from ob-gyns, turn to Your Pregnancy and Childbirth: Month to Month. Ultrasound findings diagnostic of early pregnancy loss include a mean gestational sac diameter of 25 mm or greater with no embryo and no fetal cardiac activity when the crown-rump length is 7 mm or more. Patients who choose expectant management should have -hCG levels monitored every 48 hours, and medical or surgical management should be recommended if -hCG levels do not decrease sufficiently.5, This article updates a previous article on this topic by Barash, et al.12. Most often this occurs in one of the fallopian tubes (called a tubal pregnancy) but it can also happen on the cervix or elsewhere in the abdominal region. Slowly rising hCG levels may be the first clue . The discriminatory level varies with the type of ultrasound machine used, the sonographer, and the number of gestations. See permissionsforcopyrightquestions and/or permission requests. Also searched were the Cochrane database, the Agency for Health-care Research and Quality, DynaMed, and the National Guideline Clearinghouse. One use for quantitative hCG levels is to diagnose and monitor an ectopic pregnancy or pregnancy of unknown location. The definitive diagnosis of ectopic pregnancy can be made with ultrasound visualization of a yolk sac and/or embryo in the adnexa. An ectopic pregnancy most often happens in your fallopian tube (a structure that connects your ovaries and uterus). A Cochrane review found that medical management with misoprostol (Cytotec) in women with incomplete abortion does not improve rates of completed abortion or decrease the need for unplanned surgical procedures compared with expectant management.22 In contrast, medical management is more effective than expectant management for the treatment of anembryonic gestation or embryonic demise.25 The most effective regimen for medical management is 200 mg of oral mifepristone (Mifeprex) followed 24 hours later by 800 mcg of vaginally administered misoprostol.26 Success rates at two days with this regimen are 84% vs. 67% in those treated with misoprostol alone. Your doctor may also test your progesterone levels because low levels could be a sign of an ectopic pregnancy. Burnett TL (expert opinion).
