Randomized Controlled Trial Comparative Study Clinical TrialComparison of sevoflurane-nitrous oxide and target-controlled propofol with fentanyl anesthesia for hysteroscopy.
A randomized prospective study was performed on the anesthetic induction, maintenance, and recovery characteristics of sevoflurane-nitrous oxide, compared to that of target- controlled propofol and fentanyl anesthesia, for forty day-case hysteroscopic surgery. The patients in the sevoflurane group (n = 20) received sevoflurane-nitrous oxide for both induction (8%) and maintenance (1 - 2%) of anesthesia, while the patients in the propofol group (n = 20) received target-controlled propofol (4 micro g/ml, 3-6 micro g/ml as occasion demanded) with fentanyl (1 micro g/kg). In both groups, the airway was maintained by a facemask with the patient breathing spontaneously during the surgery. ⋯ The postanesthetic Aldrete's recovery scores of the patients immediately after surgery were higher in the sevoflurane group. Propofol was associated with more drowsiness, with sevoflurane being associated with more nausea, in the recovery period; however, neither delayed the time to discharge (103.7 +/- 28.1 vs. 99.0 +/- 36.2 min). In conclusion, sevoflurane-nitrous oxide appears to be superior for day-case hysteroscopic surgery, than target-controlled propofol with fentanyl, with regards to the speed of recovery from anesthesia and the return to hemodynamic stability.

Effect of induced and spontaneous hypothermia on survival time of uncontrolled hemorrhagic shock rat model.
We examined the hypothesis that mild hypothermia (rectal temperature 34 degrees C) results in the same survival time, whether induced spontaneously or intentionally, during untreated, lethal, uncontrolled hemorrhagic shock in rats. Sixty-four Sprague-Dawley male rats were randomly assigned to normothermia (Nth) (n=19), spontaneous mild hypothermia (Sp. Hth) (n=25) or controlled mild hypothermia (Con. ⋯ Hth and Con. Hth groups, respectively (p < 0.05). In conclusion, spontaneous mild hypothermia did not prolong the survival time as much as controlled mild hypothermia in the rat model for untreated, lethal, uncontrolled hemorrhagic shock.
