How Ultrasound works
How Ultrasound works samer kareem 2,506 Views • 2 years ago

Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves and their echoes. The technique is similar to the echolocation used by bats, whales and dolphins, as well as SONAR used by submarines. In ultrasound, the following events happen: The ultrasound machine transmits high-frequency (1 to 5 megahertz) sound pulses into your body using a probe. The sound waves travel into your body and hit a boundary between tissues (e.g. between fluid and soft tissue, soft tissue and bone). Some of the sound waves get reflected back to the probe, while some travel on further until they reach another boundary and get reflected. The reflected waves are picked up by the probe and relayed to the machine. The machine calculates the distance from the probe to the tissue or organ (boundaries) using the speed of sound in tissue (5,005 ft/s or1,540 m/s) and the time of the each echo's return (usually on the order of millionths of a second). The machine displays the distances and intensities of the echoes on the screen, forming a two dimensional image like the one shown below.

Childbirth (also called labour, birth, partus or parturition) is the culmination of a human pregnancy or gestation period with birth of one or more newborn infants from a woman’s uterus. The process of normal human childbirth is categorized in three stages of labour: the shortening and dilation of the cervix, descent and birth of the infant, and birth of the placenta. In some cases, childbirth is achieved through caesarean section, the removal of the neonate through a surgical incision in the abdomen, rather than through vaginal birth

Amniotomy - Breaking the bag of water prior to childbirth
Amniotomy - Breaking the bag of water prior to childbirth Doctor 285,797 Views • 2 years ago

Amniotomy is the official term for artificially breaking the bag of waters during labor. It is believed that breaking the bag of waters will help to speed up an otherwise slow labor. Amniotomy is part of the Active Management of Labor practiced in some hospitals. Amniotomy is performed by a midwife or doctor. A long, thin instrument with a hook on the end is inserted into the vagina and through the cervix so it can catch and rip the bag of waters. To perform an amniotomy, the cervix must be dilated enough to allow the instrument through the cervix, generally at least a two. Why choose Amniotomy? Unlike other medical methods of starting labor, amniotomy does not add synthetic hormones to your labor. Instead it seems to stimulate your body’s own labor process. Amniotomy allows the use of an internal electronic fetal monitor. How effective is Amniotomy? Amniotomy alone is unpredictable, it may take hours for labor to start with amniotomy. Because amniotomy increases the risk for infection, most caregivers use amniotomy in combination with synthetic oxytocin. Birth does happen faster when amniotomy is combined with synthetic oxytocin than when amniotomy is used alone. Risks of Amniotomy Risks for Mother Increases the risk for infection. This risk is increased with length of time the waters are broken and with vaginal exams. Because of the infection risk, a time limit is given by which the mother must give birth. As the time limit approaches attempts to progress labor will become more aggressive. The fore waters equalize pressure on the cervix so it will open uniformly. When they are broken, the mother increases her chances of having uneven dilation. Risks for Baby Increases the risk of umbilical cord compression. The fore waters equalize pressure on the baby’s head as it presses against the cervix. When they are broken, the pressure on the baby’s head may be uneven causing swelling in some parts.
