Randomized Controlled Trial Comparative StudyPredistention of the epidural space before catheter insertion reduces the incidence of intravascular epidural catheter insertion.
Accidental cannulation of an epidural vein is a common complication associated with epidural anesthesia or analgesia. On the basis of a pilot study and previous reports, we tested the hypothesis that predistention of the epidural space with saline before epidural catheterization would ease catheter insertion and decrease the incidence of this complication. ⋯ Distention of the epidural space with 5 mL saline before epidural catheter insertion decreased the incidence of accidental venous cannulation and the number of unblocked segments.

Randomized Controlled Trial Comparative StudySpinal ropivacaine for lower limb surgery: a dose response study.
The dose-response relationship for spinal ropivacaine in patients undergoing surgery of the lower extremity has not been fully determined. ⋯ The ED(50) and ED(95) for spinal ropivacaine in lower limb surgery of 50 min duration or less were 7.6 and 11.4 mg, respectively. This provides a useful guide for clinicians to choose the optimal dose of spinal ropivacaine under different clinical situations.

Randomized Controlled Trial Comparative StudyThe effect of leaving dentures in place on bag-mask ventilation at induction of general anesthesia.
The optimum timing for denture removal in edentulous patients before anesthesia and surgery is uncertain. ⋯ We conclude that bag-mask ventilation is easier in edentulate patients when their dentures are left in situ during induction of general anesthesia.
