2. Abortion Spontaneous abortion Induced abortion

3. Abortion Defined as delivery occurring before the 28th completed week of gestation Fetus weighing less than 1000g US ( before the 20th completed week of gestation) Early abortion and late abortion 15% of clinically evident pregnancies 80% of abortions prior to 12 weeks’ gestation

4. Abnormal karyotype: 50% Maternal factors: infection (TORCH) endocrine factors immunologic factors maternal systemic disease anatomic defects trauma Toxic factors Etiology

5. anatomic defects

23. Ectopic pregnancy

24. Definition A fertilized ovum implants in an area other than the endometrial lining of the uterus.

25. Animation of intrauterine implantation

26. Animation of ectopic implantation

27. Sites of ectopic pregnancy >95% ectopic pregs in fallopian tubes 70% ampulla 12% isthmic 11.1% fimbrial 3.2% ovarian 2.4% interstitial 1.3% abdominal

28. Etiology Tubal Factors (salpingitis, previous tubal surgery) Zygote Abnormalities (chromosomal abnormalities) Ovarian Factors (ovum into contralateral tube) Exogenous Hormone (oral contraceptives) Other Factors (endometriosis, IUD)

29. Pathology Lackage of resistance to invasion by the trophoblast Abdominal pregnancy -1:15000 pregnancies Enlarged uterus and endometrium changes

30. Termination of the pregnancy Abortion Rupture

31. Temination of the pregnancy Tubal:abortion or missed abortion Interstitial,Angular,Cornual:rupture into the uterine cavity,the broad ligament or the peritoneal cavity. Cervical:rupture into the cervical canal Abdominal:rupture into the peritoneal cavity,into the retroperitoneal space Ovarian:rupture into the peritoneal cavity

32. Clinical Findings Symptoms of early pregnancy (amenorrhea, breast tenderness, and nausea) Bleeding (usually spotting) Diffuse lower abdominal pain Over 15% of ectopic pregnant as surgical emergencies.

33. Symptoms Pain Pelvic or lower abdominal pain (99%) Generalized pain (44%) Unilateral lower abdominal pain (33%) Subdiaphragmatic pain or sharp shoulder pain (22%) Abnormal uterine bleeding (75%) Secondary amenorrhea (68%) Syncope (37%)

34. Signs Abdominal tenderness (80%) Adnexal tenderness (75%) Adnexal mass(a unilateral adnexal mass:53%) Uterine changes (normal size:71%,6-8 weeks’ size:26%, 9-12 weeks’ size:3%) Fever (only about 2% of patients)

35. Laboratory Findings Pregnancy tests (postive-82.5%) Hematocrit White blood cell count A negative test does not rule out an ectopic gestation

36. Special Examinations Utrasonically scanning Culdocentesis Dilatation and curettage Exploratory laparotomy

38. Differential Diagnosis Appendicitis Salpingitis Ruptured corpus luteum cyst Uterine abortion Twisted ovarian cyst Urinary tract disease Degenerating leiomyomas

39. Essentials of Diagnosis Amenorrhea followed by irregular vaginal bleeding Adnexal tenderness or mass Ultrasonographic evidence of adnexal mass and no intrauterine gestation Positive ß-hCG

40. Complications About I in 1000 ectopic pregnancies result in maternal death Untreated or mistreated ruptured ectopic tubal pregnancy 8-12% of all materal deaths The majority of these deaths are preventable Death

41. Complications Chronic salpingitis Infertility or sterility Intestinal obstruction may develop after hemoperitoneum and peritonitis Tubal damage

42. Treatment Emergency Treatment Immediate surgery,anti-shock(warm,oxygen) Surgical treatment laparoscopic techniques Medical treatmemt-MTX Supportive treatment antibiotic,iron therapy, a high-protein diet

43. Salpingectomy

44. Indications for Conservative Drug Therapy No signs of active intra-abdominal bleeding Diameter of mass ＜ 3cm Serum ß-hCG ＜ 2000U/L No embryonic blood vessle pounding No contraindication for MTX application Normal liver and kidney function Normal RBC count

45. Prognosis Another tubal pregnancy will occur in 10-20% of patients treated Infertility develops in approximately 50% of patients

46. Hyperemesis Gravidarum

47. Prolonged and severe nausea/ vomiting associated with dehydration, weight loss, or electrolyte disturbances when pregnancy Definition

48. Etiology Unknown Hormonal, neurologic, metabolic, toxic, and psychosocial factors (underlying emotional disorder) Degree of biochemical hyperthyroidismh The level of beta-HCGlevel o

49. Severe nausea, Waste Away Ketonuria, Increased urine specific gravity Elevated hematocrit and BUN level Hyponatremia,Hypokalemia,Hypochloremia Metabolic acidosis Wernicke-Korsakoff Deficiency of VitaminK Clinical Findings

50. –Urine –Blood –Serum Beta-HCG (Molar pregnancy) –Thyroid function –Ultrasound –EKG –Fundus oculi Diagnosis and Differential Diagnosis

51. Indication for hospitalization Intractable emesis, Correction of any electrolyte abnormalities, Hypovolemia IV hydration Parental nutrition Electrolyte supplement Treatment

52. Vitamin supplementation （ B1 ） —— Wernocke’s encephalopathy NaHCO3 Oral feedings Terminal pregnancy Treatment
