Randomized Controlled Trial Comparative Study Clinical Trial
[Postoperative delirium after general anesthesia vs. spinal anesthesia in geriatric patients].
Influence of the type of anesthesia on postoperative delirium was examined in geriatric patients with femoral neck fracture. ⋯ The type of anesthesia, general or spinal, does not affect the postoperative delirium in geriatric patients with femoral neck fracture.

Randomized Controlled Trial Clinical Trial
[Spinal anesthesia using hyperbaric bupivacaine HCl for cesarean section].
We performed this prospective study to determine the proper amount of hyperbaric bupivacaine hydrochloride as a spinal anesthetic agent for cesarean section. ⋯ 1. As a spinal anesthetic agent for cesarean section, hyperbaric bupivacaine is superior to tetracaine. 2. Hyperbaric bupivacaine 10 mg, 12.5 mg or 15 mg can be used safely and effectively as a spinal agent for cesarean section. 3. High dose bupivacaine is recommended in an urgent case, and low dose bupivacaine is recommended when maternal hypotension must be strictly avoided.

A 73-year-old female complained of pain in the right lower-abdomen and medial aspect of the distal thigh after a gynecological operation. Computer tomography and MRI findings excluded obturator canal herniation or lumbar plexopathy. ⋯ Treatment with radio-frequency lesion of 50 degrees C for 60 seconds of the right obturator nerve relieved her pain for 9 months without muscle weakness. This case shows usefulness of radiofrequency lesion for obturator nerve pain.

Case Reports
[Anesthesia for a woman with triplet pregnancy presenting with acute abdomen after the recent epidural blood patch].
We report a case of primipara with triplet pregnancy who underwent combined spinal and epidural anesthesia 10 weeks after epidural blood patch. At 15 weeks of gestation, a woman with triplet gestation underwent Shirodkar operation under spinal anesthesia and subsequent epidural blood patch as a treatment of post-dural puncture headache. At 26 weeks she presented with acute abdomen and laparotomy was scheduled. ⋯ Laparotomy revealed right paraovarian cyst torsion and the right salpingo-paraoophocystectomy was performed. Patient-controlled analgesia with epidural bupivacaine and fentanyl was effectively continued for two days. Postoperative course was uneventful and the triplets were delivered by cesarean section at 35 weeks.

We often use lidocaine adhesive tape (Penles, Wyeth Lederle Japan, Ltd., Tokyo, Japan) as a topical anesthetic prior to puncturing a vein with a needle. Since the tape is usually in place for a long time, we often experience problems with creasing and flaring when inserting the needle. We attempted to determine the optimal time for application of the tape as well as for vein puncture after its removal by measuring pain sensation in human subjects. ⋯ We concluded that lidocaine tape provided maximum pain relief when applied 4 to 6 hours prior to vein puncture and up to 1 hour after removal.
