[Epiduroscopy in patients with chronic low back pain without remarkable findings on magnetic resonance imaging].

Two patients with chronic low back pain and sciatica failed to respond to conservative treatments. In these patients, magnetic resonance imaging (MRI) showed no remarkable findings corresponding to their symptoms. We treated these patients using epiduroscopy. Epiduroscopic visualization of the spinal canal permits efficient adhesiolysis and irrigation. One patient got better after two epiduroscopic procedures, and the other did not. Epiduroscopy may be an effective, minimally invasive treatment as well as examination for patients with chronic low back pain without remarkable findings on MRI.

[Severe bradycardia and hypotension during epidural anesthesia in a patient undergoing hemorrhoidectomy].

Severe bradycardia and hypotension developed suddenly in two patients undergoing hemorrhoidectomy under lumbar epidural anesthesia in the jackknife position, about 5 to 10 min after epidural administration of buprenorphine. Severe vago-vagal reflex was supposed to have been induced with buprenorphine in a situation where venous return was decreased by epidural anesthesia and the jackknife position.

[Meralgia paresthetica after spinal anesthesia].

A 27-year-old man underwent appendectomy under spinal anesthesia with 0.3% dibucaine 2.7 ml. The perioperative course was uneventful. The surgical procedure, however, lasted for 1.5 hours in the supine position. On the second postoperative day, a postspinal headache occurred and lasted for 18 days. On the seventh postoperative day the patient complained of numbness along the anterolateral aspect of the left thigh innervated by the lateral cutaneous nerve. There was no reflex or motor deficit indicative of the involvement of other nerves. The disorder was diagnosed as meralgia paresthetica caused by the surgical procedures. The numbness disappeared after the oral administration of mecobalamin in several days. In the treatment of a case like this, it is important to exclude neurological complications caused by spinal anesthesia.

[Cardiac arrests probably induced by hypermagnesemia during anesthesia for caesarean section].

A 24-year-old pregnant woman was scheduled for Caesarean section during the 31st week of pregnancy. The patient had been treated with MgSO4 for premature labor and toxemia. During anesthesia, cardiac arrest occurred twice. The first cardiac arrest occurred immediately after induction of anesthesia and seemed to be due to combined effects of hypermagnesemia, thiopental and supine hypotensive syndrome. Three babies were delivered during cardiac massage. The second one occurred immediately after administration of methyl-ergometrine malate and seemed to be due to combined effects of hypermagnesemia and methyl-ergometrine malate. The patient and three babies did not develop any complication. In giving anesthesia for patients with hypermagnesemia, anesthetists should take account of interactions between magnesium, anesthetics and other drugs.

[A method of tracheal intubation tried in a patient with multicentric reticulohistiocytosis].

A 48-year-old woman had suffered from multiple destructive arthritis, skin nodules and skin ulcer of bilateral legs caused by multicentric reticulohistiocytosis for 16 years. Skin transplantation and total hip joint replacement were scheduled. Tracheal intubation was anticipated to be difficult because of destructive arthritis of the temporomandibular joint. We tried a new method to intubate the trachea through a laryngeal mask. After topical application of 8% lidocaine to the oropharynx, a size 4 laryngeal mask was inserted and its cuff was inflated by 20 ml of air. Anesthesia was induced with 4% sevoflurane in 50% nitrous oxide via laryngeal mask. A fiberscope through a tracheal tube was inserted through the laryngeal mask into the trachea. A tracheal tube with the internal diameter of 6.5 mm, was successfully intubated. This method gave little discomfort to the patient.
