Randomized Controlled Trial Multicenter Study Clinical Trial[N2O-free sevoflurane anesthesia. Clinical evaluation].
The characteristics of sevoflurane make it able to be used without N2O avoiding its undesirable effects to this associates. The aim of the study is to evaluate the clinical characteristics of sevoflurane anesthesia "N2O free" in comparison to sevoflurane anesthesia with N2O. ⋯ We didn't observe differences between the two groups. In conclusions, omitting N2O during sevoflurane anesthesia can be considered a safe technique, avoiding the acute and chronic side effects associated with the use of N2O, without modifying the intraop consumption of opioid, the recovery and the early postoperative incidence of nausea, vomiting and analgesia.

Randomized Controlled Trial Multicenter Study Clinical Trial Controlled Clinical Trial
Omission of nitrous oxide from a propofol-based anesthetic does not affect the recovery of women undergoing outpatient gynecologic surgery.
Although nitrous oxide (N2O) is used commonly during anesthesia, clinically relevant advantages-disadvantages of using this agent are not well established in the ambulatory setting. This study in women undergoing ambulatory gynecologic surgery compares outcomes in patients administered total intravenous anesthesia with propofol versus the propofol plus N2O. The primary outcome was the time to home readiness. Secondary outcomes included the incidence of postanesthetic adverse events. ⋯ Omission of N2O from a propofol-based anesthetic for ambulatory gynecologic surgery does not affect time to home readiness or the incidence of postoperative adverse events up to 24 h after discharge from hospital. (Key words: Awareness; outpatient surgery; total intravenous anesthesia.)

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialA comparison of anaesthesia using remifentanil combined with either isoflurane, enflurane or propofol in patients undergoing gynaecological laparoscopy, varicose vein or arthroscopic surgery.
Anaesthesia comprising remifentanil plus isoflurane, enflurane or propofol was randomly evaluated in 285, 285 and 284 patients, respectively, undergoing short-procedure surgery. ⋯ Anaesthesia combining remifentanil with volatile hypnotics or TIVA with propofol was effective and well tolerated. Times of extubation, postanaesthesia recovery and recovery room discharge were rapid, consistent and similar for all three regimens.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialA comparative study of topical vs retrobulbar anesthesia in complicated cataract surgery.
To evaluate and compare levels of patient discomfort and perioperative complications during phacoemulsification and implantation of a foldable intraocular lens under topical lidocaine hydrochloride and retrobulbar anesthesia in patients with cataract who also had exfoliation syndrome, uveitis, posterior synechia, phacodonesis, or previous intraocular surgery. ⋯ Surgery-related complications and patient discomfort were similar for the 2 methods of anesthesia. Topical anesthesia is justified as a means of improving safety without causing discomfort to the patient even in complicated cases of cataract surgery. Arch Ophthalmol. 2000;118:1037-1043

Multicenter Study
[A multicenter study of cardiac events and anesthetic management of patients with ischemic heart diseases for noncardiac surgery--a follow-up report].
We have conducted a joint research project to investigate the incidence of ischemic heart disease in patients for noncardiac surgery and to define the risk of perioperative cardiac complications in these patients. From September to November 1997 we had 7288 patients scheduled to undergo noncardiac surgery in the 8 departments of anesthesiology. ⋯ In our region of Japan, 3-4% of surgical patients tend to develop ischemic heart disease and 3.1% of them demonstrated severe cardiac complications perioperatively. Compared with United States we encounter fewer surgical patients with ischemic heart disease, but the risk of developing perioperative cardiac complications in such patients is almost the same for both countries.
