[Addition of fentanyl to mepivacaine in axillary brachial plexus block. Effects on the anesthetic and postoperative analgesic quality].

The possible potentiating effect of phentanyl on mepivacaine in brachial plexus blockade was evaluated, both for operative anesthesia and postoperative analgesia. Sixty ASA I patients, scheduled for upper limb surgery, were selected and distributed in 3 groups: 1) Mepivacaine 1% 40 ml (control group); 2) Mepivacaine 1% 40 ml + phentanyl 100 micrograms; 3) Mepivacaine 1% 40 ml + subcutaneous phentanyl 100 micrograms. The latency time and the quality of anesthesia were evaluated. The duration of analgesia was evaluated on the basis of the time from the administration of the first analgesic. There were no significant differences between the 3 groups in the latency times of the development of blockade nor in the quality of surgical anesthesia. Also, there were no significant differences in the duration of postoperative analgesia (307, 316 and 326 minutes, respectively, in each group). It was concluded that the addition of phentanyl 100 micrograms to the local anesthetic in the axillary blockade of the brachial plexus does not change the anesthetic characteristics nor the time of postoperative analgesia.

[Temperature variations of respiratory gases during episodes of anesthetic circuit disconnection in controlled ventilation].

Temperature variations of respiratory gases during episodes of disconnexion of the anesthetic circuit in controlled ventilation were measured with a temperature sensor located in the anesthetic circuit close to the endotracheal tube which was connected to a temperature monitor with alarm limits of 0.5 degrees C. We compared the activation times of the ventilator pressure alarm with those of the temperature. The activation time of the respirator alarm (8.9 +/- 1.6 sec) was significantly shorter (p less than 0.001) than that of the temperature monitor. This difference was more apparent when the anesthetic circuit was disconnected distantly from the sensor (10.5 +/- 1.8 sec for disconnexion between the tracheal tube and the sensor, and 36.8 +/- 12.2 sec when the disconnexion occurred at the entrance of the respiratory branch of the ventilator tubes). The maximal individual value for the activation time of the temperature alarm was 67 seconds. In all instances hemoglobin saturation (SpO2) during anesthetic circuit disconnexion was higher than 95%. In each group there was a positive and significant correlation between the temperature alarm time and the adjustment of the predetermined alarm level with respect to the basal temperature of the respiratory gases. Temperature monitorization of the respiratory gases did not offer additional advantages to the conventional monitorization of the respiratory circuit disconnexion.
