Abstract
Objective: to analyze the scientific evidence on the positioning of pregnant women in spinal anesthesia for cesarean section.
 Method: an integrative review of the literature in the Scopus, CINAHL, LILACS and PubMed databases using the descriptors "patient positioning", "spinal anesthesia" and "obstetrics" and their synonyms "patient position" and "spinal anesthetics".
 Results: the sample of 8 articles showed that the fastest onset of blockade in pregnant women occurs in the lateral horizontal decubitus position and in the sitting position with legs downwards. Lateral decubitus with elevated head presented insufficient blockade. Lateral position was related to greater comfort, and its maintenance for 15 minutes before the supine position, after infiltration with the anesthetic was associated with lower incidence of hypotension.
 Conclusion: Scientific evidence has shown that positioning influences the effect, potentiation and delay of anesthesia, comfort and the pregnant woman's blood pressure, being relevant to the perioperative and obstetric multidisciplinary practice.
