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 Comparative Study
Needle-free powder lidocaine delivery system provides rapid effective analgesia for venipuncture or cannulation pain in children: randomized, double-blind Comparison of Venipuncture and Venous Cannulation Pain After Fast-Onset Needle-Free Powder Lidocaine or Placebo Treatment trial.
The Comparison of Venipuncture and Venous Cannulation Pain After Fast-Onset Needle-Free Powder Lidocaine or Placebo Treatment trial was a randomized, single-dose, double-blind, phase 3 study investigating whether a needle-free powder lidocaine delivery system (a sterile, prefilled, disposable system that delivers lidocaine powder into the epidermis) produces effective local analgesia within 1 to 3 minutes for venipuncture and peripheral venous cannulation procedures in children. ⋯ The needle-free powder lidocaine delivery system was well tolerated and produced significant analgesia within 1 to 3 minutes.

Multicenter Study
Stable plasma concentrations of unbound ropivacaine during postoperative epidural infusion for 24-72 hours in children.
The aim of this open, non-controlled, multi-centre study was to evaluate the pharmacokinetics and safety of a 24-72 h continuous epidural ropivacaine infusion in children aged 1-9 yr. ⋯ Following a 24-72 h epidural infusion of ropivacaine 0.4 mg kg(-1) h(-1) in 1-9-yr-old children, the plasma concentrations of unbound ropivacaine were stable over time with no age-dependency.

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.

The French Society of Anaesthesiology (SFAR) recommends the use of pre printed self-stick syringe labels. However, French anaesthesia-syringe labelling customs is yet unknown. ⋯ Colour labels are used in France by nearly half of the centers, but international colour code is less spread.
