Case Reports
[A case of vertebral metastasis revealed by incomplete spinal analgesia for cesarean section].
A 36-year-old woman was scheduled for Cesarean section under spinal anesthesia. She was a carrier of hepatitis-B-virus and diabetic. She was complaining of low back pain. ⋯ After the delivery, she still complained of low back pain. Later examination revealed metastatic bone tumor of L2 from hepatoma. This case suggests that in a patient with such incomplete spinal or epidural anesthesia and neurological finding, vertebral metastatic tumor should be ruled out.

We evaluated retrospectively the anesthetic management and perioperative complications of 47 patients with chronic spinal cord injury for genitourinary procedures. Of the 69 cases, 38 were performed under general anesthesia, 21 cases under spinal anesthesia, one case under epidural anesthesia, four cases under axillary block, and five cases under either sedation or standby. In preoperative laboratory findings, anemia was observed in 41%, hypoproteinemia in 38%, renal insufficiency in 23%, and restrictive pulmonary dysfunction in 69%. ⋯ Careful preoperative evaluation and anesthetic management are required for prevention and prompt treatment of perioperative complications related to the disorders. Autonomic hyperreflexia can be successfully prevented by either general anesthesia or spinal anesthesia. The increased anesthesia safety can be obtained by the successful management of the cardiovascular instability during surgery.

To evaluate postoperative analgesia and side effects of epidural buprenorphine, 100 patients who underwent upper abdominal surgery were divided into 5 groups. All patients were given initially 0.1 mg of buprenorphine in 8 ml of 0.25% bupivacaine in bolus. Following an epidural bolus, 20 patients in each group were given 0.25% bupivacaine alone (group A), 5 micrograms buprenorphine in 1 ml of 0.25% bupivacaine (group B), 8 micrograms buprenorphine in 1 ml of 0.25% bupivacaine (group C), 12 micrograms buprenorphine in 1 ml of 0.25% bupivacaine (group D), or 15 micrograms buprenorphine in 1 ml of 0.25% bupivacaine (group E) with a portable disposable device at a rate of 1 ml.h-1 for 48 h. ⋯ No significant difference was found in the incidence of side-effect among 5 groups. Therefore, epidural buprenorphine 15 micrograms in 1 ml of 0.25% bupivacaine given to patients at a rate of 1 ml.h-1 was thought to be optimal for postoperative pain relief in upper abdominal surgery in terms of its efficacy and side effects. However, 35% of these patients required supplementary systemic analgesics in the early postoperative period.

A 24-year-old, 48 kg female with Charcot-Marie-Tooth disease, mitral valve prolapse syndrome and IInd degree AV block was scheduled for emergency cesarean section under epidural anesthesia. This anesthesia was chosen because she had heart disease. Furthermore, the combination of general anesthesia with neuromuscular blockade posed the risk of a prolonged response to muscle relaxants and resulting respiratory insufficiency. ⋯ Epidural anesthesia was safely performed during the operation. Postoperatively, there were no signs of respiratory or neurologic dysfunction. In conclusion, epidural anesthesia seems to be a good choice for a patient with Charcot-Marie-Tooth disease.

It has been reported that subcutaneous administration of pancuronium produces prolonged neuromuscular blockade. The purpose of this study was to evaluate the antagonistic effect of neostigmine on neuromuscular blockade following subcutaneous injection of pancuronium in anesthetized patients. Fourteen male patients aged 32-67 yr, weighing 50-58 kg, and scheduled for surgical operation lasting more than 6 hr were included in the study. ⋯ Time intervals to maximum train-of-four depression from pancuronium administration in groups A and B averaged 2.6 and 125.4 min, respectively. No significant differences in the recovery times of the train-of-four ratios from 0.2 to 0.7 following neostigmine administration in groups A and B were demonstrated. None of the patients who received pancuronium subcutaneously showed recurarization following neostigmine administration.(ABSTRACT TRUNCATED AT 250 WORDS)
