Uterine contraction. Uterine contractions are muscle contractions of the uterine smooth muscle that can occur at various intensities in both the non-pregnant and pregnant uterine state. The non-pregnant uterus undergoes small, spontaneous contractions in addition to stronger, coordinated contractions during the menstrual cycle and orgasm.
Uterine atony is the failure of the uterus to contract adequately following delivery. Contraction of the uterine muscles during labor compresses the blood vessels and slows flow, which helps prevent hemorrhage and facilitates coagulation. Therefore, a lack of uterine muscle contraction can lead to an acute hemorrhage, as the vasculature is not ...
Braxton Hicks contractions. Other names. Practice contractions, false labor. Specialty. Obstetrics. Braxton Hicks contractions, also known as practice contractions or false labor, are sporadic uterine contractions that may start around six weeks into a pregnancy. [ 1 ] However, they are usually felt in the second or third trimester of pregnancy.
After contraction takes place the fundus (top) of the uterus can be palpated as a firm mass at the level of the navel. It is important that the uterus remains firm and the nurse or midwife will make frequent assessments of both the fundus and the amount of bleeding. Uterine massage is commonly used to help the uterus contract. [11]
Oxytocin helps the uterus to contract quickly and the contractions to last longer. [21] It is the first line treatment for PPH when its cause is the uterus not contracting well. [22] A combination of syntocinon and ergometrine is commonly used as part of active management of the third stage of labour. [23] This is called syntometrine.
The postpartum physiological changes are those expected changes that occur in the woman's body after childbirth, in the postpartum period. These changes mark the beginning of the return of pre-pregnancy physiology and of breastfeeding. Most of the time these postnatal changes are normal and can be managed with medication and comfort measures ...
When the uterine muscles contract, they constrict the blood supply to the tissue of the endometrium, which, in turn, breaks down and dies. These uterine contractions continue as they squeeze the old, dead endometrial tissue through the cervix and out of the body through the vagina. These contractions, and the resulting temporary oxygen ...
Fergusson reflex. The Ferguson reflex (also called the fetal ejection reflex) is the neuroendocrine reflex comprising the self-sustaining cycle of uterine contractions initiated by pressure at the cervix, more precisely, the internal end of cervix, or vaginal walls. It is an example of positive feedback in biology.
