Randomized Controlled Trial Multicenter Study Comparative StudyThe effects of isoflurane and desflurane on cognitive function in humans.
This small, pilot study suggests that isoflurane may be more commonly associated with post-operative cognitive dysfunction than desflurane in older patients.

Multicenter Study Clinical TrialSafety and acceptability of suprascapular nerve block in rheumatology patients.
Suprascapular nerve block (SSNB) is a popular treatment for shoulder pain. To date, studies undertaken mainly describe the methods of performing the technique or are trials examining its efficacy. As a result, the numbers of blocks reported are small and therefore confidence in the safety of the procedure must be limited. ⋯ Patient satisfaction with the pain relief was high, with over 80% of respondents being satisfied or very satisfied with the result. SSNB is a very safe procedure in the outpatient setting, even among frail, elderly patients. Patients rate the satisfaction with the pain relief highly.

Randomized Controlled Trial Multicenter Study Comparative Study
Randomised, double-blind, placebo-controlled study of a single dose of an amylmetacresol/2,4-dichlorobenzyl alcohol plus lidocaine lozenge or a hexylresorcinol lozenge for the treatment of acute sore throat due to upper respiratory tract infection.
Sore throat is a frequent reason for seeking medical care but few prescription options are available. Lozenges are effective in delivering active ingredients to the throat. This study was conducted to determine the analgesic efficacy of two lozenges one containing amylmetacresol (AMC)/2,4-dichlorobenzyl alcohol (DCBA) and lidocaine and one containing hexylresorcinol versus placebo in patients with acute sore throat due to upper respiratory tract infection (URTI). ⋯ Both AMC/DCBA + lidocaine and hexylresorcinol lozenges provided rapid and effective sore throat relief in patients with URTI.

Randomized Controlled Trial Multicenter Study
The Hip Fracture Surgery in Elderly Patients (HIPELD) study: protocol for a randomized, multicenter controlled trial evaluating the effect of xenon on postoperative delirium in older patients undergoing hip fracture surgery.
Strategies to protect the brain from postoperative delirium (POD) after hip fracture are urgently needed. The development of delirium often is associated with the loss of independence, poor functional recovery, and increased morbidity, as well as increases in length of hospital stay, discharges to nursing facilities, and healthcare costs. We hypothesize that xenon may reduce the burden of POD, (i) by avoiding the need to provide anesthesia with a drug that targets the γ-amino-butyric acid (GABA)A receptor and (ii) through beneficial anesthetic and organ-protective effects. ⋯ An international, multicenter, phase 2, prospective, randomized, blinded, parallel group and controlled trial to evaluate the incidence of POD, diagnosed with the Confusion Assessment Method (CAM), in older patients undergoing hip fracture surgery under general anesthesia with xenon or sevoflurane, for a period of 4 days post surgery (primary outcome) is planned. Secondary objectives are to compare the incidence of POD between xenon and sevoflurane, to evaluate the incidence of POD from day 5 post surgery until discharge from hospital, to determine the time to first POD diagnosis, to evaluate the duration of POD, to evaluate the evolution of the physiological status of the patients in the postoperative period, to evaluate the recovery parameters, to collect preliminary data to evaluate the economical impact of POD in the postoperative period and to collect safety data. Patients are eligible if they are older aged (≥ 75 years) and assigned to a planned hip fracture surgery within 48 h after the hip fracture. Furthermore, patients need to be willing and able to complete the requirements of this study including the signature of the written informed consent. A total of 256 randomized patients in the 10 participating centers will be recruited, that is, 128 randomized patients in each of the 2 study groups (receiving either xenon or sevoflurane).

Randomized Controlled Trial Multicenter StudyThe efficacy and safety of DepoFoam bupivacaine in patients undergoing bilateral, cosmetic, submuscular augmentation mammaplasty: a randomized, double-blind, active-control study.
Breast augmentation can result in significant postsurgical pain. ⋯ DepoFoam bupivacaine trended toward benefit versus bupivacaine HCl on most efficacy measures. Due to early termination, the study was underpowered to achieve statistical significance.
