METHODS Split mouth single blind study comprising 31 healthy patients wit...

PURPOSE To examine the effect of modifying the interval between administration of saline used during the loss of resistance (LOR) method and local anesthetic on epidural anesthetic level and its quality. METHODS Seventy-three patients who received thoracic epidural anesthesia were randomly allocated into three groups; the 2, 5 and 10 min groups, according to the interval between the administr...

PURPOSE The purpose of this study was to assess children's reactions and record their sensations while receiving a warmed local anesthetic solution for dental procedures (37 degrees C; W) compared with one at room temperature (21 degrees C; RT). METHODS Forty-four children between the ages of 6 to 11 (mean age = 7.9 +/- 2.2 years) who were undergoing dental treatment participated in the study...

To compare the analgesic efficacy and safety of the sole local anesthetic ropivacaine with the combination of both local anesthetic ropivacaine and opioidergic analgesic sufentanil given epidurally on the labor pain control.After institutional review board approval and patient consent, a total of 500 nulliparas requesting epidural labor analgesia were enrolled and 481 eventually were randomized...

DESIGN Prospective, randomized, double-masked clinical trial. PARTICIPANTS AND INTERVENTION Sixty-four eyes from 61 patients undergoing vitreoretinal surgery were randomized to receive either retrobulbar or sub-Tenon's capsule injection of 5 ml o...

PULPECTOMY – Treatment Considerations Anesthesia It is essential to eliminate any sensation from the tooth being treated prior to endodontic therapy. While it is true that some necrotic teeth can be treated without anesthesia, placement of rubber dam clamps and instrumentation beyond the apex (patency filing) normally make the use of local anesthetic desirable. This is typically achieved throug...
