Background: The use of percutaneous ultrasound-directed radiofrequency is a recent technique in non-surgical therapy of some neoplastic liver lesions. Purpose of this study is to demonstrate that the use of a narcosis-free analgesia allows to perform this procedure, which is generally painful and badly by the patient., Methods: We treated 51 patients for a total of 126 procedures; the first 17 patients underwent a mono- or multipolar technique with uncooled electrodes, while the remaining 34 patients have been treated with double perfusion lumen electrodes with the chance of tipcooling. We used diidrobenzoperydol and fentanyl with a mean dose for each session of 209 micrograms for the first 17 patients and 109 micrograms for the other 34., Results: Using VAS, we obtained a painless procedure in 42 patients and mild-pain sensations in 9 patients, while one hour after the procedure painless or light-pain sensation were observed in 49 patients and mild-pain in 2 patients, which required the use of FANS i.v. At discharge, all patients were pain-free or with very light pain sensation. We reduced the intra-hospital observation of patients from 5 to 3 hours, once the technique has been modified. 4 patients complained about nausea and 1 of these emesis. We did not observe any cardiovascular, respiratory and/or neurological complications., Conclusions: The use of neuroleptanalgesia allowed us to perform the described procedure with a good feeling by the patients.

If the quality of results of organ transplantation in NITp is highly satisfactory, the same cannot be said for the number of transplants performed, which only cover 20-25% of the requirement. To understand the causes of organ shortage, a study group of Anaesthesiologists and Transplant Coordinators from the North Italy Transplant Program (NITp) investigated, through a questionnaire addressed to the Heads of 103 Intensive Care Units (ICU) in 92 Hospitals in the NITp area, some of the organizational problems linked to donor identification and treatment and to organ retrieval. The questionnaire took into consideration the number of possible donors identified in 1990, those retrieved and the causes for non retrieving organs and examined a number of variables linked both to retrieval and to ICUs and Hospitals organization. The results show that potential donors were 461: 143 (31%) were used, 138 (30%) were lost due to family opposition to organ donation, 192 (20%) for clinical reasons and 88 (19%) for organizational reasons. The latter figure represents 5% of non retrieval in the most active ICUs and increases to 50% in the Hospitals that had procured no donors in 1990. The main obstacles for ICUs to procure organ donors are: convey the Medical-Legal Committee, carry out of complicated administrative procedures, availability of round the clock specialized equipment for neurological assessment (especially for ICU outside Neurosurgical and Neurological departments), inadequate number of medical and nursing staff, most of all at night, and finally the difficulty in the management of non-traumatic cerebrovascular patients.

Various aspects of the critically ill patient sharing pain, physical distress, anxiety, environmental components, predispose him to develop some sleep disorders (SD). We studied 20 conscious patients, age 16-80 (mean 48.15 SD of mean +/- 25), undergoing ICU mean 14.3 days (SD of mean +/- 7.5), to evaluate SD rate and their possible leading causes. Through Spearman Rank test SD was related to Apache II score, admission state anxiety, satisfactory sedation, days of ICU stay and age respectively. Conclusive results showed SD rate in all our patients. Excepted a statistical trend to significativity of SD versus satisfactory sedation: RS 0.311 (threshold value for 20 patients: 0.377), no relation was found between SD and data recorded. These preliminary results emphasize the importance of looking for SD in ICU patients though many factors may play a role to develop them.

We report one case of atraumatic rhabdomyolysis associated with Echo group viral encephalitis, not complicated by acute renal failure. Clinical and bio-humoral outlines are described, characterized by favourable evolution despite high muscular enzymatic peaks. We emphasize that the positive course is probably due to the early institution of prophylactic measures, and that, anyway, the subject still remains exposed to major rhabdomyolysis risk in the presence of stress factors, including general anesthesia.
