Surgery on the shoulder often causes severe pain and, therefore, requires high doses of opiates. As postoperative pain is frequently treated inadequately, it is desirable to seek alternatives for providing effective analgesia. In a prospective study we examined the efficacy of balanced anesthesia consisting of general anesthesia combined with interscalene brachial plexus blockade for intra- and postoperative analgesia for operations on the shoulder. ⋯ CONCLUSION. The combination of ISB and GA allows a reduction in intraoperative doses of opiates and facilitates postoperative pain management. Because of the low incidence of side effects, the lack of complications, and the high degree of patient acceptance, we recommend this type of balanced anesthesia for patients undergoing shoulder surgery.

Efficacy and side effects of a continuous infusion of sufentanil following epidural administration of a single dose of 30 micrograms of the opioid were studied in 28 patients undergoing laparotomy. Patients were divided into two groups treated with either 10 micrograms/h (n = 13) or 15 micrograms/h (n = 15) and compared with regard to sufentanil plasma levels, side effects and changes in blood gases. ⋯ After the injection of a bolus of 30 micrograms sufentanil, a dose chosen according to current recommendations, a quick onset of analgesia was noted, but also sedation and respiratory depression with apneic intervals lasting up to 30 s, demonstrating both the efficacy and the possibility of unwanted and even harmful side effects associated with this kind of administration. During long-term infusion, after about 20 h PaCO2 and respiratory rate were significantly different between the two groups, which could be explained by differences in sufentanil plasma levels and a somewhat higher level of postoperative pain in the group receiving 10 micrograms/h.

Neuralgic pain during or following herpes zoster infection is a common problem in pain therapy. The current management of neuralgias due to zoster is discussed with reference to patients in a chronic pain clinic within an anesthesiology department. The courses of 80 patients followed up for at least 3 months from the pain clinic at the University Hospital in Kiel were analyzed. ⋯ If the history of zoster pain was less than 1 month, the majority of patients showed good or excellent results. On the other hand, only one-third of patients with a history longer than 6 months had adequate pain relief. Therefore, early and appropriate treatment is desirable for patients suffering from zoster neuralgias.

In 87 patients a new computerized EEG monitor was used in clinical anesthesia. Following aperiodic analysis, the Lifescan shows the computerized EEG in a striking color visualization allowing recognition of changes in the course of the EEG and of interhemispheric differences. The computerized EEG can be read after a brief training period. ⋯ The effect of combined anesthesia, however, was difficult to judge. In carotid artery surgery a quick unilateral decrease in activity and slowing of frequency indicated cerebral ischemia and quickly disappeared after insertion of a shunt. This change was particularly obvious with the new monitor.(ABSTRACT TRUNCATED AT 250 WORDS)
