Femoral nerve "sheath" for inguinal paravascular lumbar plexus block is not found in human cadavers.
To determine if a femoral nerve sheath capable of conveying local anesthetic to the lumbar plexus and the obturator nerve exists in human cadavers. ⋯ A femoral nerve sheath capable of conveying a solution to the cadaver lumbar plexus does not exist in human cadavers. Dye injected into the cadaver femoral nerve does not reach either the lumbar plexus or the obturator nerve. When 40 ml of methylene blue dye is injected into the cadaver femoral nerve, some dye usually diffuses under the iliacus muscle fascia to the lateral femoral cutaneous nerve. This study indicates that in patients the "3-in-1 block" always blocks the femoral nerve, it usually blocks the lateral femoral cutaneous nerve, but it probably does not block the lumbar plexus or the obturator nerve.

Randomized Controlled Trial Comparative Study Clinical Trial
Use of analgesics during propofol sedation: a comparison of ketorolac, dezocine, and fentanyl.
To evaluate the comparative efficacy and side effect profile of ketorolac 60 mg, dezocine 6 mg, and fentanyl 100 micrograms when used as analgesic supplements to a propofol infusion during monitored anesthesia care (MAC). ⋯ Compared with ketorolac 60 mg, fentanyl 100 micrograms and dezocine 6 mg produced a greater decrease in the propofol sedation requirement during MAC. However, the use of ketorolac in combination with propofol for MAC was associated with an improved recovery profile.

Randomized Controlled Trial Clinical Trial
Effect of intrathecal sufentanil on isoflurane requirements during lower abdominal surgery.
To determine the effect of intrathecal sufentanil on volatile anesthetic requirements during lower abdominal surgery. ⋯ Prior administration of intrathecal sufentanil significantly decreases the isoflurane requirement in surgical patients, in addition to its previously demonstrated rapid onset and receptor efficacy.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of EMLA cream versus nitrous oxide for pediatric venous cannulation.
To compare the analgesic and anxiolytic effects of nitrous oxide (N2O) when inhaled by face mask with those of a cutaneous application of a eutectic mixture of local anesthetics (EMLA) cream with lidocaine and prilocaine during pre-operative venous cannulation in children. ⋯ N2O administered by face mask appears to provide greater anxiolysis and attendant superior analgesia for pediatric venous cannulation than a cutaneous application of EMLA cream.

Randomized Controlled Trial Comparative Study Clinical Trial
Ketorolac for early postoperative analgesia.
To determine the efficacy and speed of onset of analgesia of a single dose of intravenous (IV) or intramuscular (IM) ketorolac tromethamine following major orthopedic surgery. ⋯ Despite high patient acceptability compared with placebo, the use of ketorolac as the sole analgesic failed to control postoperative pain following major orthopedic surgery. IV administration of ketorolac conferred no advantages over the IM route with regard to efficacy or speed of onset.
