They should be advised to avoid resting motionless in the supine position, and be provid- ed with guidance on LLT positions for resting. Most of the midwives believed that the supine position benefits the foetus, mother, and the midwife. Because this phenomena is so well known, standard practice is for clinicians to avoiding placing the woman in supine position for routine examinations and procedures, moving the woman into left lateral if there are signs of fetal distress in labour and also advising her to avoid the supine position herself, at least during the day (Thurlow & Kinsella, 2002). If they have found this in the well fetus, during a 30 min period in the supine position, with the mother awake, one can only speculate as to what might occur in a vulnerable fetus, whose mother is sleeping supine for several hours during the night. This position can be used to describe any organism with clear dorsal and ventral sides. 2020 Jan 13;20(1):36. doi: 10.1186/s12884-020-2726-4. These results certainly support the findings from earlier epidemiological studies, that supine sleep in pregnancy increases the risk of stillbirth, particularly in the growth‐restricted fetus. Hypotension in the supine position usually does not occur due to a compensatory rise in peripheral vascular resistance. 2017;125:254–262. The supine position is a term used in anatomy and medicine to describe an organism on its back. • The pregnant pt. 2017;12:e0179396 Association between maternal sleep practices and risk of late stillbirth: A case-control study. doi: 10.1016/j.ajog.2019.03.002.

Supine lying during pregnancy © 2018 Pelvic, Obstetric and Gynaecological Physiotherapy81 in supine lying, and select an alternative posi- tion, such as an upright posture or left-side ly- ing. Sleeping on your left side is often referred to as the “ideal” scenario during pregnancy. Epub 2017 Nov 20. Should the supine position indeed be a physiological stressor, these findings strongly suggest that healthy fetuses make adaptive responses into states which use less oxygen. There is also the lateral position where you give birth while lying on your side. A woman in the third trimester of pregnancy is predisposed to supine hypotension syndrome in pregnancy while in the supine or sitting position due to the hemodynamic and anatomic changes of pregnancy.. Cronin RS, Li M, Thompson JMD, Gordon A, Raynes-Greenow CH, Heazell AEP, Stacey T, Culling VM, Bowring V, Anderson NH, O'Brien LM, Mitchell EA, Askie LM, McCowan LME. : The supine sleep position in late pregnancy is a major risk factor for stillbirth, with a population attributable risk of 5.8% and one in four pregnant women reportedly sleeping in a supine position. In the supine position, the dorsal side or back goes towards the ground. The prone position is rarely used in medical settings in pregnancy. 2(1992) reported about “Preoxygenation of Pregnant and Nonpregnant Women in the Head-up versus Supine Position.” The results showed that after 3 min of preoxygenation, desaturation to 95% during subsequent apnea, as monitored by pulse oximetry, was more rapid in pregnant than in nonpregnant patients.

However, up to 15% of women at term can demonstrate supine hypotensive syndrome of pregnancy, defined as a decrease in systolic blood pressure of at least 15–30 mmHg.The syndrome has been demonstrated in pregnant females from the middle of the second trimester onward. Abstract: The supine sleep position in late pregnancy is a major risk factor for stillbirth, with a population attributable risk of 5.8% and one in four pregnant women reportedly sleeping in a supine position. Keywords: 1964). In addition, they provide important new information towards understanding the physiology of fetal responses to this position. may not be able to lie prone comfortably. -, O’Brien L.M., Warland J. New research shows that women can halve their risk of stillbirth by going to sleep on their side from 28 weeks pregnancy compared with sleeping in the supine position. In this issue of The Journal of Physiology Stone and colleagues (2017) have added an important piece to the puzzle of understanding the physiology of maternal supine position and fetal response, by conducting a controlled experiment monitoring both the mother and fetus during the day. It is very interesting that they found an increased likelihood of fetal quiescence in the supine position especially as this was in a group of normal healthy late third trimester pregnancies. 2019 Aug;46:1-8. doi: 10.1016/j.smrv.2019.04.006. Holding the torso at an angle is safe (as opposed to staying flat on your back).

Association between maternal sleep practices and late stillbirth—Findings from a stillbirth case-control study. reduced fetal oxygen saturation during labour in the supine position.20 Furthermore, a New Zealand study has reported that in healthy late pregnancy, when the mother is in the supine position, the fetus spends more time in behavioural state 1 (fetal quiescence) and less time in fetal behavioural state 4 All of these issues can arise from lying in the supine position during late pregnancy which can cause compression of the inferior vena Izci-Balserak B., Keenan B.T., Corbitt C., Staley B., Perlis M., Pien G.W. The ‘supine hypotension syndrome’ usually occurs in the last trimester of pregnancy, though it can also happen earlier in pregnancy or during post-partum. Supine Position and Pregnancy.

Supine Hypotensive Syndrome, or SHS, is perhaps the most misunderstood condition of pregnancy.
