Patient opinion of analgesia during external cephalic version at term in singleton pregnancy.

To assess the opinion and the level of satisfaction of patients concerning analgesia during external cephalic version (ECV), we present the results of a survey of 120 women undergoing ECV at term during a randomised controlled trial (July 2012 to February 2013) comparing remifentanil and nitrous oxide. Overall, 110 (91.7%) women said they would repeat the procedure and 111 (92.5%) that they would recommend it to another pregnant woman, with no significant differences by type of analgesia. The administration and sense of comfort were rated better in the remifentanil group (p < .01). In conclusion, the use of analgesia during ECV is associated with a high rate of willingness among women to repeat the procedure and recommend it to other pregnant women.Impact statementWhat is already known on this subject? ECV is commonly a painful manoeuvre for the woman. This pain triggers maternal reactive abdominal muscle contraction and involuntary abdominal tensing, reducing the likelihood of successful version and causing some women to reject the technique.What do the results of this study add? The use of analgesia during ECV is associated with a high rate of willingness among women to repeat the procedure and recommend it to other pregnant women. The sense of comfort during ECV was also significantly better in the remifentanil group, probably because of its greater analgesic power and greater comfort during its administration.What are the implications of these findings for clinical practice and/or further research? ECV should be carried out under analgesia, when available, not only to decrease pain but also to encourage wider adoption of the technique and enable more women to benefit from it.

Increased pain relief with remifentanil does not improve the success rate of external cephalic version: a randomized controlled trial.

INTRODUCTION: Our objective was to compare the effect of two pain relief methods (remifentanil vs. nitrous oxide) on the success rate of external cephalic version. MATERIAL AND METHODS: We conducted a randomized open label parallel-group controlled single-center clinical trial with sequential design, at Cruces University Hospital, Spain. Singleton pregnancies in noncephalic presentation at term that were referred for external cephalic version were assigned according to a balanced (1:1) restricted randomization scheme to analgesic treatment with remifentanil or nitrous oxide during the procedure. The primary endpoint was external cephalic version success rate. Secondary endpoints were adverse event rate, degree of pain, cesarean rate and perinatal outcomes. RESULTS: The trial was stopped early after the second interim analysis due to a very low likelihood of finding substantial differences in efficacy (futility). The external cephalic version success rate was the same in the two arms (31/60, 51.7%) with 120 women recruited, 60 in each arm. The mean pain score was significantly lower in the remifentanil group (3.2 ± 2.4 vs. 6.0 ± 2.3; p < 0.01). No differences were found in external cephalic version-related complications. There was a trend toward a higher frequency of adverse effects in the remifentanil group (18.3% vs. 6.7%, p = 0.10), with a significantly higher incidence rate (21.7 events/100 women vs. 6.7 events/100 women with nitrous oxide, p = 0.03). All reported adverse events were mild and reversible. CONCLUSIONS: Remifentanil for analgesia decreased external cephalic version-related pain but did not increase the success rate of external cephalic version at term and appeared to be associated with an increased frequency of mild adverse effects.

Obstetric and perinatal outcome in women with twin pregnancy and gestational diabetes.

OBJECTIVE: The aim of this study was to evaluate pregnancy complications and obstetric and perinatal outcomes in women with twin pregnancy and GDM. STUD DESIGN: An observational multicentre retrospective study was performed and 534 pregnant woman and 1068 twins infants allocated into two groups, 257 with GDM and 277 controls, were studied. MAIN OUTCOME MEASURES: Pregnant women characteristics, hypertensive complications, preterm delivery rate, mode of delivery and birthweight were analysed. RESULTS: Pregnant women with GDM were older (p < 0.001) and had higher body mass index (p < 0.001) than controls. GDM was associated with higher risk of prematurity in twin pregnancy (odds ratio 1.64, 95% confidence interval [1.14-2.32], p = 0.005). This association was based on the association with other pregnancy complications. Birthweight Z-scores were significantly higher in the GDM group (p = 0.02). The rate of macrosomia was higher in the GDM group (p = 0.002) and small for gestational age (SGA) babies were significantly less frequent (p = 0.03). GDM was an independent predictor of macrosomia (p = 0.006). CONCLUSION: The presence of GDM in twin pregnancy was associated with a higher risk of hypertensive complications, prematurity and macrosomia, but significantly reduces the risk of SGA infants. Prematurity was related to the presence of other associated pregnancy complications.
