In this randomized study, the efficacy of i.v. patient-controlled analgesia (PCA) was determined for the opioid piritramide (a pure mu-receptor agonist) and the antipyretic analgesic metamizole (Dipyrone) in three groups of patients following abdominal surgery. The doses of piritramide were 1.5 mg (40 patients) and 3 mg (40 patients) on demand. In addition, we studied the effect of 71 mg metamizole in combination with on-demand boluses of 1.5 mg piritramide in 40 patients. ⋯ The intensity of typical side effects of opioids and antipyretic analgesics (nausea, vomiting, lowering of respiratory frequency, sweating) was low and always easily controlled. The acceptance by patients, nurses, and physicians of PCA was high. PCA with on-demand intravenous injection of the combination of piritramide and metamizole improved the degree of analgesia and concomitantly reduced the opioid dose.

Comparative Study
Memory function after i.v. midazolam or inhalation of isoflurane for sedation during dental surgery.
Memory function was assessed with a recognition memory test in 40 dental patients before and after sedation with i.v. midazolam or inhalation of isoflurane. The two groups were comparable, but there was a significant impairment of memory (P less than 0.001) at the time of discharge for both words and faces after midazolam, but not after isoflurane.

The morphological distortion of the facial skeleton induced by untreated paediatric burns of the head and neck reinforces the theories of craniofacial growth and the modern principles of acute burn management and post-burn facial reconstruction.

Perioperative monitoring of the electrocardiogram during cerebral aneurysm surgery.
Electrocardiographic (ECG) abnormalities occur frequently following a subarachnoid hemorrhage and may also occur intraoperatively and postoperatively in patients undergoing neurovascular procedures. The aim of this study was to assess the relationship between ECG changes and the neurological status of the patient, the size and the location of the aneurysm, and the influence of these changes on the cardiac and neurological outcome. The preoperative ECG was analyzed in 270 patients. ⋯ Intraoperative and postoperative changes occurred in 35 and 65% of the patients, respectively, and were independent of the studied factors. There were no documented cardiac events. The presence of an abnormal preoperative ECG did not influence the neurological outcome of the patient, but fluctuating postoperative changes were associated with a worse outcome.

Most patients with very advanced cancer suffer from severe pain, and many studies have demonstrated how this pain can be sufficiently controlled. It is of great importance to find out if the findings are also true during the final stage of cancer and how the treatment must be adapted. We therefore examined the methods and efficacy of providing pain relief for dying cancer patients. ⋯ Only 4% of the patients treated in the way described experienced severe pain during the final stage of cancer. Systemic administration of drugs is very effective in relieving pain in dying patients. No signs of tolerance to opioids could be observed, even in patients who had been taking opioids for a longer period of time (average 39 days).
