Complementary methods in obstetrics are related to humanization of delivery and woman's decision on the mode of delivery in normal labor. The methods include various birthing positions, aids such as delivery chair, birthing wheel, etc., and water delivery. Results of recent studies comparing these methods with classic delivery in supine position are presented. The advantages of these alternative methods of delivery include shorter duration of delivery, reduced need of labor induction, lower use of analgesics, and women's acceptance of these methods of delivery with the same level of maternal and neonatal safety as in classic delivery. All these advantages apply to water delivery providing the prerequisities, contraindications and measures of surveillance are strictly met.
