Randomized Controlled TrialPreoperative administration of intravenous flurbiprofen axetil reduces postoperative pain for spinal fusion surgery.
The aim of the study was to investigate postoperative analgesia and the opioid-sparing effect of the preoperative administration of intravenous flurbiprofen axetil in patients undergoing spinal fusion surgery. ⋯ As compared with postoperative administration, preoperative administration of intravenous flurbiprofen axetil provides better postoperative analgesia and an opioid-sparing effect in patients undergoing spinal fusion surgery under general anesthesia.

Clinical TrialEffect of humidifying devices on the measurement of tidal volume by mechanical ventilators.
We hypothesized that expiratory tidal volume was underestimated, because a heat-moisture exchanger traps the expired vapor. We, therefore, designed patient and bench studies to investigate the accuracy of tidal volume monitoring. ⋯ Monitored expiratory tidal volume was underestimated by approximately 10%, when using a heat-moisture exchanger.

Randomized Controlled TrialEffect of peak inspiratory flow on gas exchange, pulmonary mechanics, and lung histology in rabbits with injured lungs.
The aim of this study was to evaluate, using a rabbit model, the little-known effect of different levels of peak inspiratory flow on acutely injured lungs. ⋯ In rabbits with injured lungs, high peak inspiratory flow with high tidal volume (V(T)) reduces the Pa(O(2))/FI(O(2)) ratio and increases the lung wet-to-dry ratio.

Randomized Controlled TrialEffects of a protease inhibitor, ulinastatin, on coagulation and fibrinolysis in abdominal surgery.
Ulinastatin is well known to inhibit the activity of polymorphonuclear leukocyte elastase (PMNE). The PMNE concentration correlates with the activities of coagulation and fibrinolysis. The purpose of the present study was to investigate the effects of ulinastatin, a protease inhibitor, on coagulation and fibrinolysis in abdominal surgery. ⋯ Ulinastatin could inhibit coagulation and fibrinolysis in abdominal surgery.

Effect of clonidine premedication on postoperative sore throat and hoarseness after total intravenous anesthesia.
To determine the effect of oral clonidine premedication on postoperative sore throat and hoarseness, we evaluated the incidence and severity of each of these complications in patients who underwent elective surgery in the supine position. The subjects were 82 patients, American Society of Anesthiologists (ASA) status I-III, aged 15-82 years. They were premedicated with either 150 microg oral clonidine and 20 mg raftidine (clonidine group; n = 41) or with 20 mg raftidine only (control group; n = 41) 2 h before anesthesia induction. ⋯ The incidences of sore throat and hoarseness tended to be higher in the clonidine group than in the control group; however, the difference did not reach statistical significance. There were no significant differences in the severity of these symptoms between the two groups. In conclusion, oral premedication with 150 microg clonidine did not prevent postoperative sore throat or hoarseness, and may have exacerbated these symptoms.
