RESUMEN
OBJECTIVE: To describe a single manual infusion technique for total intravenous anesthesia with remifentanil and propofol. MATERIAL AND METHODS: Descriptive study of a series of 30 women classified as ASA 1 or 2 who received total intravenous anesthesia by means of a single manual infusion of a combination of remifentanil and propofol for laparoscopic gynecology procedures. The patients received 5 microg of remifentanil plus 2 mg of propofol per milliliter of normal saline solution. The rate of infusion was established according to remifentanil requirements and modified in accordance with the bispectral (BIS) index. RESULTS: Sufficient hemodynamic stability was maintained in all patients, with BIS values between 40 and 60. The average time until awakening was 5.2 minutes after the anesthetic infusion had been halted. CONCLUSIONS: Total intravenous anesthesia by means of a single manual infusion of remifentanil and propofol provided appropriate anesthetic and surgical conditions, with rapid, predictable awakening.

A 5700-square-kilometer quiet zone occurs in the midst of the locations of more than 4000 earthquakes off the Pacific coast of Nicaragua. The region is indicated by the seismic gap technique to be a likely location for an earthquake of magnitude larger than 7. The quiet zone has existed since at least 1950; the last large earthquake originating from this area occurred in 1898 and was of magnitude 7.5. A rough estimate indicates that the magnitude of an earthquake rupturing the entire quiet zone could be as large as that of the 1898 event. It is not yet possible to forecast a time frame for the occurrence of such an earthquake in the quiet zone.
