Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Multicenter randomized comparison of the efficacy and safety of xenon and isoflurane in patients undergoing elective surgery.
All general anesthetics used are known to have a negative inotropic side effect. Since xenon does not have a negative inotropic effect, it could be an interesting future general anesthetic. The aim of this clinical multicenter trial was to test the hypothesis of whether recovery after xenon anesthesia is faster compared with an accepted, standardized anesthetic regimen and that it is as effective and safe. ⋯ This first randomized controlled multicenter trial on the use of xenon as an inhalational anesthetic confirms, in a large group of patients, that xenon in oxygen provides effective and safe anesthesia, with the advantage of a more rapid recovery when compared with anesthesia using isoflurane-nitrous oxide.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Comparison of ropivacaine-fentanyl patient-controlled epidural analgesia with morphine intravenous patient-controlled analgesia for perioperative analgesia and recovery after open colon surgery.
To compare the effects of ropivacaine-fentanyl patient-controlled epidural analgesia (PCEA) with morphine intravenous (IV) patient-controlled analgesia (PCA). ⋯ Ropivacaine-fentanyl PCEA provides superior analgesia, reduced opioid requirement, and more rapid recovery after colon surgery.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
A double-blind, randomized study comparing postoperative pain management using epidural ropivacaine with intravenous ketorolac or intravenous ketorolac alone following transabdominal hysterectomy.
The aim of this study is to compare the effect on postoperative pain of epidural ropivacaine in combination with intravenous ketorolac with intravenous ketorolac alone following transabdominal hysterectomy. ⋯ We demonstrated that epidural infusion of ropivacaine in addition with intravenous ketorolac gave superior pain relief at rest and on coughing in patients undergoing transabdominal hysterectomy when compared to the group receiving intravenous ketorolac alone.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Low-flow sevoflurane compared with low-flow isoflurane anesthesia in patients with stable renal insufficiency.
Sevoflurane is degraded to compound A (CpA) by carbon dioxide absorbents containing strong base. CpA is nephrotoxic in rats. Patient exposure to CpA is increased with low fresh gas flow rates, use of Baralyme, and high sevoflurane concentrations. CpA formation during low-flow and closed circuit sevoflurane anesthesia had no significant renal effects in surgical patients with normal renal function. Preexisting renal insufficiency is a risk factor for postoperative renal dysfunction. Although preexisting renal insufficiency is not affected by high-flow sevoflurane, the effect of low-flow sevoflurane in patients with renal insufficiency is unknown. ⋯ There were no statistically significant differences in measured parameters of renal function after low-flow sevoflurane anesthesia compared with isoflurane. These results suggest that low-flow sevoflurane anesthesia is as safe as low-flow isoflurane and does not alter kidney function in patients with preexisting renal disease.

Patient State Index: titration of delivery and recovery from propofol, alfentanil, and nitrous oxide anesthesia.
The Patient State Index (PSI) uses derived quantitative electroencephalogram features in a multivariate algorithm that varies as a function of hypnotic state. Data are recorded from two anterior, one midline central, and one midline posterior scalp locations. PSI has been demonstrated to have a significant relation to level of hypnosis during intravenous propofol, inhalation, and nitrous oxide-narcotic anesthesia. This multisite study evaluated the utility of PSI monitoring as an adjunct to standard anesthetic practice for guiding the delivery of propofol and alfentanil to accelerate emergence from anesthesia. ⋯ Patient State Index-directed titration of propofol delivery resulted in faster emergence and recovery from propofol-alfentanil-nitrous oxide anesthesia, with modest decrease in the amount of propofol delivered, without increasing the number of unwanted events.
