Randomized Controlled Trial Multicenter Study
Medial Open Transversus Abdominis Plane (MOTAP) Catheters Reduce Opioid Requirements and Improve Pain Control Following Open Liver Resection: A Multicenter, Blinded, Randomized Controlled Trial.
Conventional management of pain following open liver resection involves intravenous, patient-controlled analgesia (IV PCA) or epidural analgesia. The objective of this trial was to assess the efficacy of a regional technique called Medial Open Transversus Abdominis Plane (MOTAP) catheter analgesia compared with IV PCA. ⋯ MOTAP catheter analgesia reduces opioid requirements, pain, and length of hospital stay compared with IV PCA following open liver resection with subcostal incisions.

Randomized Controlled Trial Multicenter Study
Emergence times and airway reactions during general anaesthesia with remifentanil and a laryngeal mask airway: A multicentre randomised controlled trial.
What did they do?
Kowark and friends randomised 343 patients across four German hospitals to receive desflurane, sevoflurane or propofol for maintenance anesthesia using a laryngeal airway for surgery expected to be up to 2 hours.
And they found?
There was no difference in airway reactions among the three groups, and the desflurane patients emerged (statistically) significantly faster.
Hang on...
But the difference in emergence times was, i) at most only 2 minutes, and ii) was a surrogate marker for what actually matters – when a patient leaves the PACU or hospital – which wasn't reported.
Additionally, the study protocol very prescriptively defined when volatiles were decreased (50% at 5 min before expected surgical finish) and ceased – the same for both Des and Sevo. Yet it is common practice to begin weaning Sevo earlier than Des if trying to achieve comparable emergence.
Could this even be applied to my patients?
Probably not. Unless you are in the habit of using remifentanil infusions (0.15 mcg/kg/min) for surgery that almost certainly does not justify its use and have access to uniquely European analgesics piritramide and metamizole.
The elephant in the room...
Why do we persist in trying to find new justifications for desflurane, given its expense and high environmental costs? (And for that matter, remifentanil?!).
This study demonstrates the well known faster pharmacokinetics of desflurane during an unnecessarily complex laryngeal mask anesthetic, and yet adds little to meaningful clinical outcomes.
summary -
The management of neuropathic pain and pain related to bone vaso-occlusive crises in sickle cell disease remains challenging in children. Lidocaine 5% patches are recommended in adults for neuropathic pain treatment, but they are not recommended in children. The purpose of this study was to assess the efficacy and tolerance of lidocaine 5% patches in pediatric inpatients. ⋯ Although lidocaine 5% patches decreased the pain's intensity in nearly half of the enrolled patients with an excellent tolerance, the efficacy endpoint was not reached. Further studies should consider a more refined selection of the experimental population to assess the efficacy of lidocaine 5% patches in the pediatric population.

Multicenter Study Observational StudyAn Exploratory Study of Sevoflurane as an Alternative for Difficult Sedation in Critically Ill Children.
To analyze the effectiveness of inhaled sevoflurane in critically ill children with challenging sedation. ⋯ Inhaled sevoflurane appeared to be an effective sedative agent in critically ill children and can be useful in those patients on mechanical ventilation difficult to sedate with conventional drugs. It can be administered easily in the PICU with conventional ventilators using the AnaConDa system. Withdrawal syndrome may occur with prolonged treatment.

Randomized Controlled Trial Multicenter Study
Systemic effects of epidural steroid injections for spinal stenosis.
This analysis of the lumbar epidural steroid injections for spinal stenosis multicenter randomized controlled trial data identifies the degree of and risk factors for cortisol suppression after epidural steroid injections in older adults with spinal stenosis. Four hundred patients aged 50 years and older with back or leg pain and central lumbar spinal stenosis completed baseline demographic and psychosocial measures. Morning serum cortisol levels were measured at baseline and 3 weeks after initial injection. ⋯ The effect on 3-week cortisol changes did not differ by demographic or patient-level characteristics. Those treated with methylprednisolone or triamcinolone had an average 3-week cortisol reduction of 41.0% (P = 0.005) and 41.6% (P < 0.001) from baseline, respectively, whereas patients treated with betamethasone or dexamethasone were not significantly different than comparable patients in the lidocaine arm. The higher rates of cortisol suppression at 3 weeks in those receiving epidural corticosteroid injections, particularly with longer-acting insoluble corticosteroid formulations, are consistent with sustained systemic absorption of corticosteroid.
