Randomized Controlled Trial
Effects of epinephrine in the epidural space on the incidence of blood vessel injury by epidural catheter insertion for cesarean section: a prospective, randomized, double-blind study.
To evaluate the effects of epinephrine (1:200,000) in the epidural space on the incidence of blood vessel injury by epidural catheter insertion for cesarean section. ⋯ Twenty-five micrograms of epinephrine (1:200,000) in the epidural space does not reduce the incidence of blood vessel injury induced by insertion of an epidural catheter.

Randomized Controlled Trial Comparative Study
A prospective study comparing the onset and analgesic efficacy of different concentrations of levobupivacaine with/without dexmedetomidine in young children undergoing caudal blockade.
To investigate the onset and analgesic effect of adding dexmedetomidine to levobupivacaine for caudal block in young children. ⋯ Dexmedetomidine added to levobupivacaine does not have a significant effect on the onset time; however, it prolongs the duration of analgesia during caudal block in children.

Observational Study
The impact of breastfeeding on postpartum pain after vaginal and cesarean delivery.
Oxytocin may play a role in pain modulation. The analgesic effects of breastfeeding with its associated endogenous oxytocin release have not been well investigated. To determine the impact of breastfeeding on incisional, perineal, and cramping pain after cesarean and vaginal delivery. ⋯ There was no analgesic effect on incisional pain during breastfeeding, indicating that endogenous oxytocin associated with breastfeeding may not play a significant role in postpartum cesarean wound pain modulation. Breastfeeding increased cramping pain after vaginal and cesarean delivery. The increase in cramping pain is most likely due to the breastfeeding-associated oxytocin surge increasing uterine tone.

Comparative Study
The adductor canal block provides effective analgesia similar to a femoral nerve block in patients undergoing total knee arthroplasty-a retrospective study.
To determine the ability of an ultrasound-guided single-shot adductor canal block to provide adequate analgesia and improve performance during physical therapy. ⋯ Within the first 24 hours, a single-shot adductor canal block provides equally effective analgesia when compared with a femoral nerve block and improves postoperative physical therapy performance.
