“…On the other hand, our data contrast with those of Gupta et al [3], who found no significant change in inlet and outlet dimensions between patients in the sitting and squatting positions using lateral radiographic pelvimetry; however, those authors attributed this result to the limited size of their study population (25 assessable views).…”

“…he respective merits of supine versus upright (e.g., squatting, hand-to-knee, and sitting in birthing stools) birthing positions have been debated for centuries, with concerns ranging from the strictly scientific to the modish or politically correct [1][2][3][4][5]. An accurate characterization of the impact of posture on pelvic bony dimensions, however, has been lacking, although in 1969, using conventional outlet radiography, Russell [6] reported that a change from the supine to the sitting position significantly increased interspinous diameter both in the last trimester of pregnancy and 6 weeks after childbirth.…”

“…The increased normal vaginal delivery rate in the kneeling position may be because of more efficient uterine contractions in the kneeling position, increased anteroposterior outlet diameter and transverse outlet diameter reported in the upright position. 1,2,4,6,7 The normal vaginal delivery rate among primigravida women was found to be higher in the kneeling group, 89.6% versus 79.1%, RR-2.275; 95% CI 0.7872 to 6.5831. Though the caesarean delivery rates were decreased in kneeling group 2% vs 10.5% in supine group, RR-0.1820; 95% CI 0.02234 to 1.483, the difference was not statistically significant.…”

“…Historically women were instinctively adopting upright positions for delivery as they experienced stronger, more efficient and less painful uterine contractions, faster descent of foetal head due to gravitational pull, improved alignment of foetal passage, and increase in the pelvic outlet diameters, hence shorter labour duration. 1,2,4,6,7 These positions also decrease the need for operative vaginal deliveries and caesarean section rate. 1,2,4,6 Delivery in squatting position has been described to be associated with higher degree of intrapartum and postpartum pain which is attributed to the tissue edema caused by constant pressure on the pelvic floor.…”

INTRODUCTIONThere is no ideal position for labour and delivery, the standard recommendation is to encourage and support the parturient to deliver in the position she feels most comfortable in.1,2 Although international guidelines advice against being recumbent or supine for long periods of time during labour, women are motivated to deliver in the supine position at most delivery centres in India. Women delivering in the supine position experience comparatively painful prolonged labors with increased incidence of foetal distress due to more aortocaval compression by the gravid uterus.1-5 However, supine position in the second stage of labour is favoured by most obstetricians as they are trained to take delivery in this position. It allows them to monitor the labour process better with ease of providing anaesthesia, enables them to give proper perineal support in the second stage of labour, and conduct operative vaginal deliveries.Upright labour positions have several physiological advantages over the supine position. Historically women were instinctively adopting upright positions for delivery as they experienced stronger, more efficient and less ABSTRACT Background: Women delivering in upright position have shorter labour due to efficient and stronger contractions with faster descent of foetal head. The present study aimed to find out effect of upright kneeling position in the second stage of labour on maternal and foetal outcome and assess patients' satisfaction. Methods: The study was carried out in a tertiary care hospital of North India from October 2012 to February 2014. Low risk women admitted in early labour were divided into two groups, women delivering in kneeling position and in supine position. The outcome measures studied were, duration of second stage of labour, mode of delivery, 2 nd degree perineal tears, Apgar scores at 5 minutes, NICU admission rate and patient satisfaction. Results: The mean duration of second stage of labour in kneeling group was shorter by 14.901 minutes. The rate of vaginal delivery was comparable for both primigravidas and multigravida in kneeling and supine groups, RR: 2.275, 95% CI (0.7872-6.5831) and RR: 1.633, 95% CI (0.393-6.775). Primigravidas had more 2 nd degree perineal tears in kneeling group as compared to supine, RR 4.191, 95% CI (1.54 to 11.41). No difference in Apgar scores >7 at 5 minutes was observed in both groups, however, significantly lesser babies in kneeling group were admitted in NICU, RR 0.246, 95% CI (0.079 to 0.761). There was no difference on comparing satisfaction scores of primigravidas and multigravida in both supine and kneeling position. Conclusions: Kneeling position reduces the duration of second stage of labour and NICU admissions.

“…He found that during both time periods, the pelvic outlet diameter was greater when the women were sitting than when lying supine. On the other hand, in 1991, Gupta et al, using x‐ray pelvimetry, found no change in inlet or outlet dimensions between sitting and squatting positions (2).…”
