Uterine hyperstimulation or hypertonic uterine dysfunction is a potential complication of labor induction. This is displayed as Uterine tachysystole- the contraction frequency numbering more than five in a 10-minute time frame or as contractions exceeding more than two minutes in duration. [1]
This procedure also leaves no scars on the uterus which makes further pregnancies and births safer for the mother. [1] Another important factor in treating obstructed labor is monitoring the energy and hydration of the mother. [11] Contractions of the uterus require energy, so the longer the mother is in labor the more energy she expends.
The most common cause of postpartum hemorrhage is a loss of muscle tone in the uterus. Normally, the uterus will contract to constrict blood vessels and decrease the flow of blood to prevent bleeding out. However, if there is a loss of muscle tone, see uterine atony, there is an increased risk of bleeding. Oxytocin is the first-line ...
In hypertonic solutions water flows out of the cell and the cell shrinks (plasmolysis). In hypotonic solutions, water flows into the cell and the cell swells ( turgescence ). Osmotic shock or osmotic stress is physiologic dysfunction caused by a sudden change in the solute concentration around a cell , which causes a rapid change in the ...
Uterine pressure is generally measured through an intrauterine pressure catheter. Montevideo units can be more simply calculated by summing the individual contraction intensities in a ten-minute period, a process which should arrive at a result identical to the original method of calculation.
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 ...
The decrease in the coordination of uterine smooth muscles cells reduces the effectiveness of contractions, causing the uterus to enter a state of uterine quiescence. [8] During the beginning of labour, contractions may initially be intermittent and irregular, [ 7 ] but will transition into a more coordinated pattern as the labour progresses. [ 7 ]
Hypotonia is a state of low muscle tone [1] (the amount of tension or resistance to stretch in a muscle), often involving reduced muscle strength. Hypotonia is not a specific medical disorder, but a potential manifestation of many different diseases and disorders that affect motor nerve control by the brain or muscle strength.
