Randomized Controlled Trial Comparative Study
[Efficacy of spinal anesthesia with small-dose lidocaine in ambulatory prostate biopsy procedures for elderly patients : comparison with propofol anesthesia].
Opinions differ as to what is more appropriate anesthetic technique for elderly patients undergoing ambulatory surgery. The objective of this study is to compare the efficacy and safety of spinal anesthesia with small-dose lidocaine and those of propofol general anesthesia in elderly patients undergoing ambulatory prostate biopsy. ⋯ Spinal anesthesia with 10 mg of hyperbaric 1% lidocaine may be more preferable to propofol anesthesia in elderly patiens undergoing ambulatory prostate biopsy, with respect to safety and costs.

Randomized Controlled Trial
[Optimal dose of fentanyl for postoperative epidural analgesia after thoracic surgery].
We investigated the dose of fentanyl in ropivacaine for epidural anesthesia that will provide effective analgesia with minimal side effects after thoracic surgery. ⋯ We conclude that continuous epidural administration of more than 15 microg x hr(-1) of fentanyl in ropivacaine provides pain relief and few side effects after thoracic surgery.

A 74-year-old man with gastric cancer was complicated with abdominal aortic aneurysm. A two-stage operation was scheduled (repair of abdominal aortic aneurysm and subsequent gastrectomy). He also had severe chronic obstructive pulmonary disease (COPD). ⋯ In both operations, sufficient analgesia was provided with epidural anesthesia, and the surgeons rated muscle relaxation as satisfactory. No respiratory complications developed postoperatively. Maintaining spontaneous breathing during abdominal surgery using epidural anesthesia and light general anesthesia is a good option for COPD patients.

In U.S.A., Pulse CO-Oximetry has emerged as a quick, simple, and non-invasive diagnostic modality to measure the concentration of COHb in arterial blood. To investigate its efficiency, we measured COHb levels by employing Pulse CO-Oximetry and by CO-Oximeter in arterial blood. ⋯ The correlation coefficient between the COHb level by Pulse CO-Oximetry and that in the blood sample was not so high, but Pulse CO-Oximetry has the potential of changing the way victims of CO exposure are diagnosed and treated, because of its easiness.

Ultrasound-guided techniques for peripheral nerve blocks are gaining popularity in the community of anesthesiology. This technique has many clinical benefits for regional anesthesia in the field of clinical anesthesia. These are; 1. short time for procedures; 2. peripheral nerves, blocking needles and surrounding structures around the nerves are easily recognized, and; 3. the decreased incidence of complications with insertion of the needles. The knowledge, basic considerations and some techniques of ultrasound-guided peripheral nerve blocks are described in the following articles.
