Randomized Controlled Trial Multicenter Study Comparative Study
Continuous wound infiltration or epidural analgesia for pain prevention after hepato-pancreato-biliary surgery within an enhanced recovery program (POP-UP trial): study protocol for a randomized controlled trial.
Postoperative pain prevention is essential for the recovery of surgical patients. Continuous (thoracic) epidural analgesia (CEA) is routinely practiced for major abdominal surgery, but evidence is conflicting on its benefits in this setting. Potential disadvantages of epidural analgesia are a) perioperative hypotension, frequently requiring additional intravenous fluid boluses or prolonged use of vasopressors; b) relatively high failure rates, with periods of inadequate analgesia; and c) the risk of rare but serious, at times persistent, neurologic complications (hematoma and abscess). In recent years, continuous (subfascial) wound infiltration (CWI) plus patient-controlled analgesia (PCA) has been suggested as a safe and reliable alternative, which does not have the previously mentioned disadvantages, but evidence from multicenter trials targeting a specific surgical population is lacking. We hypothesize that CWI+PCA is equally as effective as CEA, without the mentioned disadvantages. ⋯ POP-UP is a pragmatic trial that will provide evidence of whether CWI+PCA is noninferior as compared to (P)CEA after elective hepato-pancreato-biliary surgery via laparotomy in an enhanced recovery setting. If this hypothesis is confirmed, this finding could contribute to more widespread implementation of this technique, especially when the described disadvantages of epidural analgesia are less often observed with CWI+PCA.

Randomized Controlled Trial Multicenter Study Comparative StudyLocal infiltration analgesia versus continuous interscalene brachial plexus block for shoulder replacement pain: a randomized clinical trial.
Shoulder replacement involves significant post-operative pain, which is often managed by continuous interscalene brachial plexus block. Catheter displacement and complications limit the beneficial effect of the block. Local infiltration analgesia (LIA) has provided good results in knee replacement. We aimed to assess the effectiveness of LIA for pain after shoulder replacement. ⋯ The LIA technique cannot be recommended for shoulder replacement unless substantially modified. Occurrence of inadequate analgesia and complications following interscalene brachial plexus block prompt further studies into pain management after shoulder replacement.

Randomized Controlled Trial Multicenter StudyGreater occipital nerve blockade for the treatment of chronic migraine: a randomized, multicenter, double-blind, and placebo-controlled study.
We aimed to assess the efficacy of greater occipital nerve (GON) blockade at chronic migraine (CM) treatment. ⋯ Our results suggest that GON blockade with bupivacaine was superior to placebo and was found to be effective, safe, and cost-effective for the treatment of CM. According to our knowledge, this is the first randomized, multicentre, double-blind, and placebo-controlled study in the literature in this field of work.

Multicenter Study
General anaesthetic agents do not influence persistent pain after breast cancer surgery: A prospective nationwide cohort study.
It has recently been suggested that propofol exerts a protective effect on the occurrence of persistent pain after breast cancer surgery. We analysed data from a subcohort taken from a multicentre study to validate this information. ⋯ There does not appear to be a role for the anaesthetic protocol in the occurrence of persistent postsurgical pain. Other already well established hypotheses were confirmed.

Multicenter StudyAssociations Between Age and Dosing of Volatile Anesthetics in 2 Academic Hospitals.
The inverse relationship between age and dose requirement for potent volatile anesthetics is well established, but the question of whether anesthetic providers consider this relationship in practice remains unanswered. We sought to determine whether there is an association between patient age and the mean dose of volatile anesthetic delivered during maintenance of anesthesia. ⋯ Increasing age is associated with decreased absolute doses of potent volatile anesthetics, an association that seems to strengthen as patients enter the geriatric age range. The observed decreases in absolute anesthetic dose were less than those predicted by previous research and therefore represent an overall increase in "age-adjusted dose" as patients grow older.
