The medication levels are very low to decrease the side effects to both mother and baby.
10 Nonetheless, giving very large volumes into the epidural space may spread the block both higher and lower.The technique of "single-shot" lumbar epidural anaesthesia was first developed in 1921 by Spanish military surgeon.24 Epidurals (other than low-dose ambulatory epidurals 25 ) preclude maternal movement, but "walking, movement, and changing positions during labor help labor progress, enhance comfort, and decrease the risk of complications." 26 One study concluded that women whose epidural infusions contained fentanyl were less likely.46 Epidural veins can be inadvertently punctured with the needle during the procedure.2 The level of the spine at which the catheter is best placed depends mainly on the site and type of an intended operation or the anatomical origin of pain.Injection of analgesics and steroids into the epidural space may improve some forms of back pain.Bubeck J, Boos K, Krause H, Thies KC (2004).Journal of the American Medical Association.American Journal of Surgery.This would seem a fine experiment for testing the first hypothesis."Pain relief in labour".
