Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
A multicenter, randomized, controlled trial comparing bupivacaine with ropivacaine for labor analgesia.
A meta-analysis of studies comparing high doses of bupivacaine with ropivacaine for labor pain found a higher incidence of forceps deliveries, motor block, and poorer neonatal outcome with bupivacaine. The purpose of this study was to determine if there is a difference in these outcomes when a low concentration of patient-controlled epidural bupivacaine combined with fentanyl is compared with ropivacaine combined with fentanyl. ⋯ There was no difference in the incidence of operative delivery or neonatal outcome among nulliparous patients who received low concentrations of bupivacaine or ropivacaine for labor analgesia.

Randomized Controlled Trial Clinical Trial
Auricular acupressure as a treatment for anxiety in prehospital transport settings.
Auricular acupuncture at the relaxation point has been previously shown to be an effective treatment for anxiety in the preoperative setting. The purpose of this prospective, randomized, blinded study was to determine whether auricular acupressure can reduce stress and anxiety during ambulance transport. ⋯ It was concluded that auricular acupressure is an effective treatment for anxiety in prehospital emergency settings.
