Review Historical ArticleHistory and evolution of regional anesthesiology and acute pain medicine fellowship training.
In 2016, individual training programs in regional anesthesiology and acute pain medicine (RA/APM) became eligible for accreditation by the Accreditation Council for Graduate Medical Education (ACGME), thereby culminating a process that began 15 years earlier. Herein, we review the origins of regional anesthesia training in the USA, the events leading up to accreditation and the current state of the fellowship. ⋯ The history of RA/APM training in the USA is a tortuous one. It began with short 'apprenticeships' under the tutelage of the early proponents of regional anesthesia and continues today with 84 official RA/APM programs and a robust fellowship directors' group. RA/APM programs teach skills essential to the practice and improvement of anesthesiology as a specialty.

Centralized pain and pain catastrophizing mediate the association between lifetime abuse history and self-reported pain medication side effects.
Self-reported side effects of pain medication are important determinants of treatment course that can affect patient adherence, medication discontinuation and physician decisions. Yet, few studies have investigated patient-level predictors of self-reported pain medication side effects. The present study sought to fill this gap by exploring the impact of physical or sexual abuse history on self-reported pain medication side effects and considered a mediation model in which those effects are transmitted through a centralized pain phenotype and pain catastrophizing. ⋯ This suggests that individuals who experience abuse may develop a heightened physiological sensitivity to stimuli, as well as a tendency to interpret stimuli negatively, exaggerate the impact of aversive stimuli and undermine their ability to cope with the stressor. This study highlights the need for physicians to understand patient-level predictors of medication tolerance and to consider a history of abuse and trauma in decisions regarding treatment and medication management.

Randomized Controlled TrialEvaluation of ultrasound-guided rhomboid intercostal nerve block for postoperative analgesia in breast cancer surgery: a prospective, randomized controlled trial.
Mastectomy has many potential sources of pain. Rhomboid intercostal block (RIB) is a recently described plane block. The primary hypothesis of the study is that ultrasound-guided RIB combined with general anesthesia would accelerate global quality of recovery scores of patients following mastectomy surgery. Secondary hypothesis is that RIB would reduce postoperative opioid consumption, pain scores, and the need for rescue analgesia. ⋯ In the current study, ultrasound-guided RIB promoted enhanced recovery and decreased opioid consumption after mastectomy surgery.

Randomized Controlled TrialMotor-sparing effect of iPACK (interspace between the popliteal artery and capsule of the posterior knee) block versus tibial nerve block after total knee arthroplasty: a randomized controlled trial.
An ultrasound-guided anesthetic technique targeting the interspace between the popliteal artery and capsule of the posterior knee (iPACK) can provide posterior knee analgesia with preserved motor function after total knee arthroplasty (TKA). This study compared the peroneal nerve motor-sparing effects of iPACK block and tibial nerve block (TNB) when combined with local infiltration analgesia (LIA) and continuous adductor canal block (CACB). ⋯ Compared with TNB, iPACK1 and iPACK2 preserved CPN and tibial nerve motor function to a greater extent. However, iPACK2 did not demonstrate complete CPN and tibial nerve motor blockade while maintaining effective posterior knee pain relief.

ReviewTechnical considerations for approaches to the ultrasound-guided maxillary nerve block via the pterygopalatine fossa: a literature review.
Blockade of the trigeminal nerve and its branches is an effective diagnostic tool and potential treatment of facial pain. Ultrasound-guided injections in the pterygopalatine fossa (PPF) to block the trigeminal nerve divisions and sphenopalatine ganglion have been described but a consensus has yet to be reached over the ideal approach. We sought to delineate and compare the various approaches to the ultrasound-guided trigeminal divisions blockade via the PPF. ⋯ These studies demonstrated that the PPF is a readily accessible target for the ultrasound-guided maxillary nerve block via three main approaches.2 The ideal approach is yet to be determined and must be further explored.
