Propofol target-controlled infusion (TCI) is now commonly used for the induction and maintenance of anesthesia. In this study, we measured the propofol plasma concentrations of elderly patients to evaluate our hypothesis that propofol TCI is reliable for use in elderly patients. ⋯ We concluded that propofol TCI is a reliable method for maintaining anesthesia even in elderly patients, whereas the individual differences of the elderly patients was greater than those obtained from normal patients.

Randomized Controlled Trial Clinical Trial
[The efficacy of intravenous lidocaine for acute herpetic pain--placebo controlled trial].
Acute herpetic pain (AHP) which is considered not only nociceptive pain but also neuropathic pain, is often severe and intractable. Although there have been reports of the efficacy of intravenous lidocaine (IVL) for neuropathic pain, the efficacy of lidocaine for AHP is not known. Therefore, the effect of IVL for AHP was examined. ⋯ This study demonstrates that IVL has a significant analgesic effect in patients with AHP.

Comparative Study
[A pilot assessment of the FloTrac cardiac output monitoring system comparing with pulmonary artery catheter method by three versions].
Clinical significance of PA catheter is controversial. FloTrac sensor bases its calculations on arterial waveform characteristics. We conducted a pilot assessment of the FloTrac sensor by three versions comparing with pulmonary artery catheter (PCA) methodology. ⋯ CO measured by a new semi-invasive arterial pressure waveform analysis device showed better agreement with pulmonary artery thermodilution measurement of the newer version.

Case Reports
[A case of neuropathic cancer pain in the lower extremities successfully treated with spinal cord stimulation].
A 76-year-old man was referred to our pain clinic for the treatment of bilateral lower extremity pain due to metastasis of renal cell carcinoma to the sacrum. The pain could not be controlled with narcotics, antidepressant or the epidural block. ⋯ Therefore, spinal cord stimulation (SCS) was performed, relieving the pain until death, 6 months after its induction. This case shows the usefulness of SCS for neuropathic cancer pain that shows signs similar to those of benign disease.
