Randomized Controlled TrialIntrathecal Morphine for Laparoscopic Segmental Colonic Resection as Part of an Enhanced Recovery Protocol: A Randomized Controlled Trial.
Management of postoperative pain after laparoscopic segmental colonic resections remains controversial. We compared 2 methods of analgesia within an Enhanced Recovery After Surgery (ERAS) program. The goal of the study was to investigate whether administration of intrathecal bupivacaine/morphine would lead to an enhanced recovery. ⋯ This study was registered at ClinicalTrials.gov, identifier NCT02284282.

Review Practice GuidelineThe European Society of Regional Anaesthesia and Pain Therapy/American Society of Regional Anesthesia and Pain Medicine Recommendations on Local Anesthetics and Adjuvants Dosage in Pediatric Regional Anesthesia.
Dosage of local anesthetics (LAs) used for regional anesthesia in children is not well determined. In order to evaluate and come to a consensus regarding some of these controversial topics, The European Society of Regional Anaesthesia and Pain Therapy (ESRA) and the American Society of Regional Anesthesia and Pain Medicine (ASRA) developed a Joint Committee Practice Advisory on Local Anesthetics and Adjuvants Dosage in Pediatric Regional Anesthesia. ⋯ High-level evidence is not yet available to guide dosage of LA used in regional blocks in children. The ASRA/ESRA recommendations intend to provide guidance in order to reduce the large variability of LA dosage currently observed in clinical practice.

The experimental use of lipid emulsion for local anesthetic toxicity was originally identified in 1998. It was then translated to clinical practice in 2006 and expanded to drugs other than local anesthetics in 2008. Our understanding of lipid resuscitation therapy has progressed considerably since the previous update from the American Society of Regional Anesthesia and Pain Medicine, and the scientific evidence has coalesced around specific discrete mechanisms. ⋯ Other mechanisms have diminished in favor based on lack of evidence; these include direct effects on channel currents (eg, calcium) and mass-effect overpowering a block in mitochondrial metabolism. In this narrative review, we discuss these proposed mechanisms and address questions left to answer in the field. Further work is needed, but the field has made considerable strides towards understanding the mechanisms.

Comparative StudyEthnic Differences Identified by Pain Sensitivity Questionnaire Correlate With Clinical Pain Responses.
The Pain Sensitivity Questionnaire, English version (PSQ-E), is predictive of pain-related responses to experimental stimuli. Ethnic differences have been noted in experimental measures of pain sensation using quantitative sensory testing. The present study sought to determine if the PSQ-E also identified similar ethnic differences. ⋯ The study demonstrated significantly elevated pain sensitivity in AA compared with NHW patients as measured by the PSQ-E and experimental and clinical pain intensity scores. This shows that the PSQ reflects the known elevation of pain sensitivity in AA subjects and suggests that it may be useful in assessing pain treatment disparities by identifying and standardizing differences in pain sensitivity.

Case ReportsErector Spinae Plane Block for Surgery of the Posterior Thoracic Wall in a Pediatric Patient.
Historically, regional anesthesia for surgery on the posterior thoracic wall has been limited to neuraxial and paravertebral nerve blocks. The erector spinae plane (ESP) block is a novel technique that anesthetizes the dorsal rami of the spinal nerves innervating the posterior thoracic wall. We report the use of the ESP block for this clinical application in a pediatric patient. ⋯ The ESP block is an effective option for surgery on the posterior thoracic wall. The opioid- and anesthetic-sparing effects exhibited in this case facilitated rapid postoperative recovery and early discharge.
