Lack of benefits of left tilt in emergent cesarean sections: A randomized study of cardiotocography, cord acid-base status and other parameters of the mother and the fetus

Abstract

No benefits were found in performing cesarean section in left lateral tilt.

Part 12: Cardiac Arrest in Special Situations

“…106 Two studies found no improvement in maternal hemodynamic or fetal parameters with 10°to 20°left-lateral tilt in patients not in arrest. 107,108 One study reported more aortic compression at 15°l eft-lateral tilt compared with a full left-lateral tilt. 97 In addition, aortic compression has been found at Ͼ30°of tilt, 109 however the majority of these patients were in labor.…”

Hemodynamic effects of a right lumbar–pelvic wedge during spinal anesthesia for cesarean section

“…The first compares the left or right tilted supine position with the full left lateral position. 14-17 The second compares lateral or tilted supine positions with the complete supine position, [18][19][20][21] and the third compares different locations of wedges or right-tilted vs. left-tilted positions. 22,23 The current study could be classified in the last of these three groups because it compared the use of a lumbar-pelvic wedge with the complete supine position.…”

Part 8: Advanced Life Support

“…448 Two studies found no improvement in maternal hemodynamic or fetal parameters in nonarrest patients with 10 to 20°left lateral tilt. 449,450 One study found more aortic compression at 15°left lateral tilt when compared to a full left lateral tilt. 442 In addition, aortic compression has been found to persist at over 30°of tilt; 451 however, the majority of these patients were in labor.…”
