Objective:
To evaluate the effectiveness and safety of Foley catheter and hyaluronidase for cervical ripening.
Method:
Randomized controlled trial where 140 pregnant women, with gestational age > or = 37 weeks, indication for labor induction and an unripe cervix, were enrolled, allocated in two groups according to the method of cervical ripening before labor induction. Statistical analysis used Student's t-test, Mann-Whitney, Chi-square test, survival analysis, risk ratios and number needed to treat.
Results:
Time of induction, dose of oxytocin and mode of delivery had better results in the Foley catheter group. Comfort with the method was higher in the hyaluronidase group.
Conclusions:
Both methods were effective and safe for cervical ripening. The Foley catheter group experienced a shorter period of induction, required a lower dose of oxytocin and had higher vaginal delivery rates, while the women who used hyaluronidase declared greater comfort with the method.

Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
