Main author (year) country | Obstetric predictors of successful or unsuccessful MR | Maternal predictors of successful or unsuccessful MR | Other predictors of successful or unsuccessful MR |
Shaffer 2006 USA | Labour induction and EDA were associated with higher rates of CD, but none of these factors increased the rate of failed rotation. | Multipara women and women under 35 years were more likely to have a successful MR. | No Data |
Le Ray 2007 France | Attempted rotation before full dilatation tripled the risk of failure compared with rotation at full dilatation. MR for failure to progress increased the risk of failure compared with prophylactic rotation. No engagement (above station 0) increased the risk of failure. | Nulliparity and age > 35 were risks of failure. | Risk factors for failure increased with the number of attempts. 69.6% succeeded on the first occasion, but none of the fourth or fifth attempts were successful. MR at night failed twice as often compared with during the day |
Sen 2013 Japan | MR has a better chance of success if the foetal head is at station 0, or further down. |
| There was no significant difference between the successful rotation rate when MR and Posture change were compared. |
