  Lithotomy position - Biocrawler   (Site not responding. Last check: 2007-09-11)
The position is often used for women to give birth in, also for anal and vaginal examinations, as well as anal, rectal, and vaginal surgery.
However, the position is not conducive to a smooth labor as it constricts the birth canal, puts pressure on the coccyx and does not allow the woman to move (which reduces the pain of labour).
The origin of the position, and hence the name, was in the earliest method of lithotomy, the surgical removal of a bladder stone, in which an incision was made in the perineum.

The position is often used for women to give birth in, also for anal and vaginal examinations, as well as anal, rectal, and vaginal surgery.
However, the position is not conducive to a smooth labor as it constricts the birth canal, puts pressure on the coccyx, prevents the fetal ejection reflex from occurring and does not allow the woman to move (which reduces the pain of labour).

 Lithotomy - Wikipedia, the free encyclopedia
Lithotomy from Greek for "lithos" (stone) and "thomos" (cut), is a surgical method for removal of calculi, stones formed inside certain hollow organs, such as the bladder and kidneys (urinary calculus) and gallbladder (gallstones), that cannot exit naturally through the urethra, ureter or biliary duct.
Special surgical instruments were designed for lithotomy, consisting of dilators of the canal, forceps and tweezers, lithotomes (stone cutter) and cystotomes (bladder cutter), urethrotomes (for incisions of the urethra) and conductors, (grooved probes used as guides for stone extraction).
The patient is placed in a special position in a lithotomy surgical table, called the lithotomy position (which, curiously, retains this name until present for other unrelated medical procedures).

 * Lithotomy Position - (Pregnancy & Parenting): Definition
The lithotomy position is a delivery position where a woman lies on her back with her feet held up in stirrups.
While the lithotomy position (mother on her back with legs elevated in stirrups) is gradually losing favor as the ideal birth position, some providers continue to insist on this position at the time of birth.
I later discovered that the lithotomy position for a delivery with the baby in the position she was in can actually cause the monitor to read a problem where none actually exists.

 Lithotomy Position
In one study, by far the most popular upright position among women given the option was the supported squat, in which the woman gives birth on a bed supported in a squatting position by a special "birth cushion," which allows most of the woman's weight to rest on her thighs instead of her feet.
This lithotomy position completes the process of symbolic inversion that has been in motion since the woman was put into that "backwards" hospital gown.
When the discrepancy between scientific fact and actual practice becomes as obvious as it is with the lithotomy position, that model must either be abandoned altogether (as have many such paradigms of the past) or be expanded to accomodate at least the most compelling pieces of scientific evidence that challenge its standard operating procedures.

 Pushing Positions - Childbirth Resources at StorkNet's Childbirth Cubby
The lithotomy position, with a mother flat on her back and her feet in stirrups, was once the standard position in hospitals for women to give birth and in some hospitals it still is. Current obstetrical practices during second stage were developed with the attendant, rather than the birthing mother, in mind.
Lithotomy was believed to be the ideal position for doctors to deliver the baby while sitting or standing in attendance.
Although they allow a more physiologically superior position to lithotomy in terms of the mother's participation and comfort level, they still are inferior to traditional positions assumed by mothers in response to their body's signals.

The positions for giving birth have been subject to some of the same influences that have changed positions for labor; lithotomy is now nearly universal in Western birth.
The lithotomy position is in direct contradiction to basic principles of anatomy and physiology.
This is perhaps the optimum position for birth, as the muscles of the anterior abdominal wall exert a compressive force, with the pelvis fixed in a pelvic rock.

 AORN Journal: Heel and calf capillary-support: pressure in lithotomy positions   (Site not responding. Last check: 2007-09-11)
Two features characterize the lithotomy positions: the legs are elevated above the level of the aorta and a capillary bed is compressed between the supported member (ie, heel or calf) and the supporting device (ie, sling, stirrup).
In the low and standard lithotomy positions, the calf is parallel to the surface on which the patient lies so the leg also can be supported at the calf by a sling, rather than using the heel as the sole weight-bearing support.
A serious complication of the exaggerated lithotomy position was reported by researchers in 1997 (7) The patient was a 50-year-old man diagnosed with prostatic carcinoma.

 HON Mother & Child Glossary, Second Stage of Birth: Delivery
suggest that an upright (vertical) position or a lateral tilt during the second stage of labour show greater advantages than a dorsal (on the back) position.
The upright position gives less discomfort and difficulty in bearing down, less labour pain, less perineal /vaginal trauma and wound infections.
The classic lithotomy position (with the legs in stirrups) is often experienced as less comfortable and more painful and restricted in movement.

 Pushing Positions
If women were allowed to birth in positions they assumed naturally, the Gaskin Maneuver, moving to a hands and knees position, would easily be done and thus far has proven to be the most successful position for resolving shoulder dystocia.
This is especially important when the baby is in a less than optimal position, such as posterior (baby’s back is to the mother’s back), deflexed, asynclitic (baby’s head is crooked in the mother’s pelvis), or a hand is also presenting with the baby’s head.
Often movement is all that needed during labour to turn the baby’s head or allow correction of position in order for the baby to negotiate the mother’s pelvis and this is not the case when a woman is not allowed to change position during pushing.

After all, the TV screen in the labor room is positioned so that the view is best from the semi-recumbent position in the bed, so women just naturally get into bed and slide down into that position.
