Does subanesthetic isoflurane affect the ventilatory response to acute isocapnic hypoxia in healthy volunteers?
We observed an important effect of the study conditions on the effects that 0.1 MAC isoflurane has on the hypoxic ventilatory response. A depressant effect of subanesthetic isoflurane was found only when external stimuli to the subjects were absent. With extraneous audiovisual stimuli the effect of isoflurane on the response to hypoxia was more variable. On the average, however, the response then was not depressed by isoflurane.
Postoperative drainage by double pigtail stent was used more often by surgeons in the beginning of their RIRS experience and was associated with longer operation time. Nevertheless, the postoperative drainage type did not modify the outcomes regarding the postoperative complication rate, the length of hospital staying and the stones free rate.
