  • Welcome to this module in which we will be discussing obstetrics and gynecology.

  • Upon completion of this module, you should be able to: Define terms associated with female

  • reproductive anatomy; define terms associated with the process of labor; discuss cultural

  • values affecting pregnancy; identify special considerations of adolescent pregnancy; summarize

  • the normal physiology of pregnancy; list and describe signs and stages of labor; list components

  • of assessment for an obstetrical patient; identify the contents of an obstetrics kit;

  • state indications of an imminent delivery; list steps for a normal delivery; discuss

  • initial care of the newborn; summarize neonatal resuscitation procedures; describe complications

  • of pregnancy, labor, delivery, and postpartum; discuss gynecological emergencies; and, describe

  • the age-related variations for pediatric and geriatric assessment and management of the

  • female patient. You should also be able to appreciate the

  • emotions that a sexual assault victim may be experiencing.

  • Lastly, as a portion of a subsequent classroom lab, you should be able to: Demonstrate the

  • steps to assist in the normal delivery of a baby; demonstrate the steps to assist in

  • complicated deliveries; demonstrate infant neonatal procedures; demonstrate post-delivery

  • care of an infant; demonstrate the post-delivery care of the mother; demonstrate the steps

  • in management of the mother with excessive bleeding; and, demonstrate completing a prehospital

  • care report for patients with obstetrical or gynecological emergencies.

  • A women�s external genitalia, referred to as the vulva, consists of four major structures:

  • the labia minora, labia majora, clitoris, and vaginal vestibule or orifice.

  • The labia minora consists of two thin inner folds of skin within the vestibule of the

  • vagina. The labia majora is comprised of the outer

  • folds of skin and adipose tissue surrounding the vaginal opening; this structure defines

  • the lateral boundaries, if you will, of the external female genitalia.

  • The clitoris is a small, elongated erectile organ located anteriorly on the vulva.

  • The vaginal vestibule or orifice is the opening to the vagina. The opening is protected by

  • the labia minor and majora. These structures are all contained within

  • an area known as the perineum. The perineum is a diamond-shaped area corresponding to

  • the outlet of the pelvis. Both men and women have a perineum. In women, the area encompasses

  • the vulva as well as the anus. It is bounded by the coccyx posterior, the pubic arch anterior,

  • and the inside of the thighs laterally. Also located within this are is the urethra,

  • a membranous tube that extends from the urinary bladder to the exterior of the body for the

  • voiding of urine. Moving to the internal female reproductive

  • organs, the uterus is a muscular, hollow organ located along the midline in most women�s

  • lower abdominal quadrants. The organ is designed for implantation of a fertilized egg where

  • it can develop into a fetus. During the final stages of pregnancy, the uterus is also responsible

  • for labor and muscular contractions for expulsion of the baby.

  • Ovaries are small, round organs located on either side of most women�s lower abdominal

  • quadrants. These organs are responsible for producing ova (eggs) for conception. The ovaries

  • also produce many of the hormones necessary for the process of reproduction.

  • The ovaries and uterus are connected via fallopian tubes. When an egg is released from an ovary,

  • it travels down the fallopian tube into the uterus. If fertilization of an egg occurs,

  • it commonly does so while in a fallopian tube. In a normal pregnancy, the fertilized egg

  • will continue its journey down the fallopian tube into the uterus for implantation and

  • continued development. Given a pregnancy, the woman is carrying a

  • fetus and other supportive structures. The fetus is simply the developing baby within

  • the uterus. At eight weeks of development, the fetal stage officially begins. From that

  • point, until delivery, the developing baby is referred to as a fetus.

  • The placenta is attached to the wall of the uterus and exchanges oxygen, nutrients, and

  • wastes between the mother and the fetus through the umbilical cord.

  • The umbilical cord contains blood vessels that carry blood containing oxygen and nutrients

  • to the baby, as well as vessels that transport blood with fetal waste products back to the

  • placenta and the mother. Some additional terms and definitions as they

  • relate to labor and delivery are as follows: Labor is the process of having (or delivering)

  • a baby. While various resources define labor as consisting of either three or four stages,

  • it is commonly held to begin with the first uterine muscle contraction and it ends once

  • the placenta is expelled from the woman. Bloody show is mucus and blood that may be

  • expelled from the vagina as labor begins. Presenting part is the body part of the baby

  • that exits the labor canal first. While this is commonly the head, given a typical delivery,

  • it can also be an arm, leg, or buttocks. Crowning is the appearance of the fetal scalp

  • at the vaginal orifice during delivery. Spontaneous abortion, also known as a miscarriage,

  • is the delivery of the product of conception early in pregnancy (before the 20th week).

  • While EMS providers must be culturally sensitive in all patient interactions, calls involving

  • obstetrics and gynecology are even more critical in this regard. Women in all cultures have

  • a value system that will affect their pregnancy. This can include how the woman cares for herself

  • during the pregnancy as well as how they have planned the childbirth process. In some cultures,

  • for instance, it is not permissible for the woman to have a male healthcare provider assisting

  • in the delivery. These cultural differences may also involve social, psychological, and

  • emotional factors. In some cultures, being pregnant is associated with achieving status

  • and recognition within their family unit. For some women, on the other hand, being pregnant

  • results in a lower self-esteem. As an EMS provider, respect these differences and honor

  • the patient�s requests, remembering that any competent adult has the legal right to

  • refuse any part of assessment or care. Adolescent pregnancy is rampant in the United

  • States with UNICEF reporting in 2001 a birth rate of 52.1 per 1,000, the highest in the

  • developed world and more than twice the European average. As of 2011, the CDC has reported

  • a teen birth rate of 31.3. While this rate has decreased over the course of 10 years,

  • the CDC also recognizes a tremendous disparity in teen birth rates between racial and ethnic

  • groups with rates anywhere from approximately 10 to 50 per 1,000 based upon the race or

  • ethnicity of the group. In many instances, socioeconomic factors seem to be involved

  • and one reason why teen pregnancy is deemed socially undesirable is illustrated by the

  • CDC statistic that one-half of pregnant teenagers do not finish high school. The trickle-down

  • effect of that is an inability for the mother to find employment and earn a livable wage

  • without that basic level of education. Regardless the factors surrounding a teenage pregnancy,

  • the EMS provider assessing a pregnant teenage female must be professional and non-judgmental

  • at all times. Depending on the age of the patient, providing care may be complicated

  • by the level of physical and psychological maturity and development of the patient. Additionally,

  • a pregnant minor is still a minor, meaning that her parents may still have the legal

  • authority to authorize or decline healthcare for her. (Remember from the legal module of

  • this course that Wisconsin does not commonly recognize emancipated minors as other states

  • do.) It can also be common, depending on how long the patient has been pregnant, for her

  • to not know about the pregnancy, to be in denial about the pregnancy, or to have not

  • told her parents about the pregnancy. When assessing female patients, especially those

  • with gastrointestinal or abdominal complaints, always consider the possibility of the patient

  • being pregnant. Also keep in mind the patient�s need for independence and privacy. If possible,

  • it may be better for the teenage patient if any assessment is performed or history is

  • obtained away from her parents. If you have not covered it yet, one of the

  • modules within this course will discuss the legal obligation of an EMT to report to law

  • enforcement any suspected child abuse or neglect. This becomes pertinent when discussing adolescent

  • pregnancies because it is considered sexual abuse of a child in Wisconsin for a person

  • to have sex with a minor under the age of 16 (meaning 15 years of age or younger). If

  • the minor is either 16 or 17 years of age, the crime is a misdemeanor that is not considered

  • sexual abuse of a child and is not subject to the mandatory reporting requirements of

  • state statute 48 (sections 48.02 and 48.981). If the sex was nonconsensual, it is considered

  • sexual abuse of a child, regardless of the victim�s age. Remember as well that it takes

  • time for a pregnancy to show. Just because a pregnant female is 16, 17, or 18 years of

  • age at the time of an EMS contact does not mean she was that age at conception. The law

  • also does not consider the age of the individual who had sex with the pregnant female, so just

  • because the father is also a minor does not necessarily mean a crime did not occur.

  • If providing care to a pregnant, minor female, it is recommended that the EMT contact law

  • enforcement to report the incident and law enforcement can then make a determination

  • as to whether or not the statutory requirements for sexual assault of a minor were met.

  • For the woman who becomes pregnant, she is about to experience numerous, significant

  • changes to her body. Her reproductive system begins producing increased

  • hormones to support fetal development. These hormones will commonly impact the woman�s

  • emotional status. The respiratory system must begin handling

  • greater oxygen demand while pressure on the diaphragm from the developing fetus results

  • in a decreased minute volume. As a result, the mother�s respiratory rate is commonly

  • faster than it would be if she were not pregnant. The cardiovascular system must meet the demand

  • for oxygen and other nutrients for the fetus, which results in an increase in both blood

  • volume as well as the heart rate. The fetus commonly places pressure on the mother�s

  • vena cava, which can impact the effectiveness of circulation to her lower extremities and

  • clotting factor changes occur to accommodate the fetus.

  • The musculoskeletal system must adapt to changes in the woman�s center of gravity given the

  • addition of a developing fetus, which can result in back pain, leg pain, and fatigue,

  • especially in the later stages of fetal development. The body also must prepare for the process

  • of delivery and the joints loosen, especially in the hips, which can cause instability for

  • the mother. The gastrointestinal system is also impacted

  • by the pregnancy. Digestion slows, which can lead to nausea and vomiting. The fetus also

  • places pressure on the bladder and intestines, which results in increased need to urinate

  • and possible incontinence. For the purposes of providing emergency medicine,

  • it is important to understand the timeline associated with conception and fetal development

  • as medical emergencies associated with pregnancy can vary in terms of type and severity over

  • the duration of a pregnancy. The process begins with ovulation in which

  • the ovaries discharge an egg. Fertilization occurs if a male sperm is introduced to the

  • female egg. Once the egg is fertilized, it must then implant itself into the lining of

  • the uterus. (If this implantation takes place someplace else, an ectopic pregnancy will

  • result. This type of medical emergency will be discussed a little later in this module.)

  • The next stage is called the embryonic stage, which is the period of time from fertilization

  • to about eight weeks afterward. The last stage is the fetal stage, which begins approximately

  • eight weeks after fertilization (after the embryonic stage) until delivery, approximately

  • 40 weeks after fertilization. Before discussing the delivery of a baby,

  • the EMT must be able to recognize the signs of labor.

  • Lightening, also referred to as the baby dropping, is a sensation of pressure caused by the descent

  • of the uterus into the pelvic cavity. This occurs as the fetus changes position within

  • the uterus to prepare for delivery. In first-time mothers, this is commonly noticeable a few

  • weeks prior to delivery. For women who have delivered before, this sensation may not be

  • noticeable until just prior to delivery. Braxton Hicks contractions are sporadic uterine

  • contractions that occur during pregnancy. These can start as early as six weeks into

  • the pregnancy for some women. Typically, most women will not notice them, even if they are

  • occurring, until sometime in the mid- to late-second trimester. As the delivery date nears, Braxton

  • Hicks contractions may increase in frequency, becoming rhythmic and relatively close together.

  • They may also produce pain, which can lead some women to believe they are entering labor.

  • The difference between Braxton Hicks contractions and true labor contractions is that these

  • false labor contractions do not grow consistently longer, stronger, and closer together. If

  • the woman has not reached her 37th week yet and the contractions are becoming more frequent,

  • rhythmic, or painful, that may be a sign of preterm labor. If the woman is past 36 weeks,

  • contractions that last longer than a minute and occur within five minutes of each other

  • for at least an hour may be indicative of the start of labor.

  • Cervical dilation begins to occur as the woman nears labor. Because the cervix cannot be
