Randomized Controlled Trial Multicenter StudyVaginal twin delivery: a survey and review of location, anesthesia coverage and interventions.
Twin pregnancies are associated with increased perinatal morbidity and mortality. No consensus exists whether vaginal twin delivery should take place in the labor room or operating room, or whether anesthesiologists should be present. We surveyed members of the California Society of Anesthesiologists (CSA) to review management of vaginal twin delivery, and examined anesthetic intervention retrospectively at our institution. ⋯ There is a lack of consensus regarding the appropriate location for vaginal twin delivery and the role of anesthesiologists. A significant percentage of women undergoing vaginal twin delivery in our institution received anesthetic intervention in the immediate delivery period.

Randomized Controlled Trial Multicenter StudyCan regional analgesia reduce the risk of recurrence after breast cancer? Methodology of a multicenter randomized trial.
Surgery is the primary and most effective treatment of breast cancer, but minimal residual disease is probably unavoidable. Whether residual disease results in clinical metastases depends on numerous factors, including anti-tumor cell mediated immunity and angiogenic and growth signals in sites of residual disease. At least three perioperative factors adversely affect these: 1) the neuroendocrine stress response to surgery, 2) volatile anesthetics, and 3) opioids. ⋯ Enrolling 1100 patients over 5 years will provide 85% power for detecting a 30% treatment effect at an alpha of 0.05. We plan four equally spaced interim analyses, each evaluating efficacy and futility. Confirming our hypothesis will indicate that a small modification to anesthetic management, one that can be implemented with little risk or cost, will reduce the risk of cancer recurrence - a complication that is often ultimately lethal.

Randomized Controlled Trial Multicenter Study Comparative StudySufentanil-propofol vs remifentanil-propofol during total intravenous anesthesia for neurosurgery. A multicentre study.
In a randomised, prospective multi-centre study, we compared the intraoperative and postoperative effects of two opioids: sufentanil and remifentanil, in combination with propofol in two groups of patients undergoing neurosurgery. ⋯ There were no significant differences between the groups in the duration of surgery and anesthesia, mean arterial pressure, heart rate, time to eye opening or extubation. The incidence of vomiting, respiratory depression and shivering was similar in both groups. Postoperative pain requiring supplemental analgesics was significantly lower in the sufentanil group (P<0.05). Although there were no significant differences between the groups in postoperative behavioural examinations by Rancho Los Amigos Test, patients anesthetised with sufentanil had significantly better Short Orientation-Memory-Concentration Test values at 15 and 180 min postoperatively (P<0.05). CONCLUSION. We conclude that remifentanil and sufentanil are suitable adjunct to propofol for total intravenous anesthesia (TIVA). Patients receiving sufentanil have reduced analgesic requirements and better cognitive function postoperatively than those who received remifentanil.

Randomized Controlled Trial Multicenter Study
Levobupivacaine for epidural anaesthesia and postoperative analgesia in hip surgery: a multi-center efficacy and safety equivalence study with bupivacaine and ropivacaine.
The aim of this randomized, single blind phase IIIb study was to evaluate the efficacy of 0.5% levobupivacaine versus 0.5% bupivacaine and 0.75% ropivacaine administered as epidural anesthesia and 0.125% levobupivacaine versus 0.125% bupivacaine and 0.2% ropivacaine for postoperative analgesia. The study was designed to test the equivalence of the overall profile of levobupivacaine against bupivacaine and ropivacaine. In addition, parameters of clinical safety were assessed. ⋯ The efficacy of epidural levobupivacaine for hip surgery and postoperative analgesia is equivalent and shows a comparable clinical profile to bupivacaine and 50-60% higher concentrated ropivacaine. The results of this equivalence study confirm suggestions derived from previous comparative studies.

Multicenter Study[Cross-sectional survey of anaesthetic practices in Catalonia, Spain].
The aim of this is study was to describe the epidemiology of anaesthesia practice in Catalonia, Spain, in 2003. ⋯ Females, older patients, or those with poor physical status make high demands on resources, as do procedures in obstetrics, orthopaedics and ophthalmology. These needs must be planned for in the organization of services and training.
