Comparative Study
[Influence of intraoperative fentanyl and remifentanil infusion on early postoperative oral intake after general anesthesia].
There is no reports on influence of intraoperative fentanyl and remifentanil infusion on ability of oral intake after short stay surgery under general anesthesia. ⋯ With or without the use of remifentanil, greater the amount of fentanyl used, greater the percentage of patients unable to eat. Amount of fentanyl used in R group was significantly less than in group NR; however the difference in percentage of patients unable to eat supper was not observed.

Comparative Study
[Comparison of continuous cardiac output measurement methods: non-invasive estimated CCO using pulse wave transit time and CCO using thermodilution].
esCCO (estimated continuous cardiac output, Nihon Kohden, esCCO) is a new cardiac output measurement system which uses pulse wave transit time to calculate cardiac output continuously and non-invasively. One of the most commonly used methods to monitor cardiac output is continuous cardiac output CCO (Edwards Lifesciences) which has an accuracy equivalent to that of thermodilution method. ⋯ This result suggests that esCCO could be used to measure cardiac output accurately and non-invasively in different cases.

Case Reports
[Case of successful management with mirtazapine for prolonged pain after esophagectomy].
This case report describes a successful outcome of mirtazapine treatment in a patient with difficult post-thoracotomy pain. A 63-year-old man received thoracotomy for the resection of esophageal tumor. The pain continued 2 years after the operation. ⋯ Since then, his weight slightly increased and the administration of mirtazapine was stopped in accordance with the patient's request. The pain became worse again. Therefore, mirtazapine, commonly used as an antidepressant agent, was considered to be beneficial for neuropathic pain as an analgesic adjuvant.

Lumbar spine disease in the elderly people is complicated by a variety of pathophysiology in the spine and the cause of the pain is unclear. Diagnosis of pain may be difficult in patients with pain in the thigh and groin area. Sacroiliac joint is supporting the trunk and movable joint. We examined the effect of the sacroiliac joint block for intractable low back pain. ⋯ Block at the posterior sacroiliac ligament region significantly reduced pain for chronic intractable low back pain. The block was shown to be effective as a treatment and for diagnosis.

Randomized Controlled Trial Comparative Study
[Long-term effects of pulsed radiofrequency on the dorsal root ganglion and segmental nerve roots for lumbosacral radicular pain: a prospective controlled randomized trial with nerve root block].
Although pulsed radiofrequency (PRF) method for lumbosacral radicular pain (LSRP) is reportedly effective, there are no prospective controlled trials. We assessed the long-term efficacy of PRF of the dorsal root ganglion and nerve roots for LSRP as compared with nerve root block (RB). ⋯ This study indicates that PRF adjacent to the dorsal root ganglion and nerve roots for LSRP has long-term effects. There were no significant differences of long-term effects between the two groups.
