Thoracic sympathetic ganglion blocks: real-world outcomes in 207 chronic pain patients.
Thoracic sympathetic ganglion block (TSGB) is a procedure to manage sympathetically maintained upper extremity pain (sympathetically maintained pain). To date, only a few studies have evaluated the clinical effectiveness of TSGB in pain medicine. This study investigated (1) the relationship between technical success of TSGB and pain reduction in patients with chronic upper extremity pain and (2) relevant clinical factors for a positive TSGB outcome. ⋯ We found no significant association between the temperature increase and pain reduction after TSGB. Further studies are warranted to identify significant factors associated with TSGB outcomes in patients with complex regional pain syndrome and neuropathic pain diseases.

Practice GuidelineEvidence-based clinical practice guidelines on postdural puncture headache: a consensus report from a multisociety international working group.
Postdural puncture headache (PDPH) can follow unintentional dural puncture during epidural techniques or intentional dural puncture during neuraxial procedures such as a lumbar puncture or spinal anesthesia. Evidence-based guidance on the prevention, diagnosis or management of this condition is, however, currently lacking. This multisociety guidance aims to fill this void and provide practitioners with comprehensive information and patient-centric recommendations to prevent, diagnose and manage patients with PDPH. ⋯ These clinical practice guidelines for PDPH provide a framework to improve identification, evaluation and delivery of evidence-based care by physicians performing neuraxial procedures to improve the quality of care and align with patients' interests. Uncertainty remains regarding best practice for the majority of management approaches for PDPH due to the paucity of evidence. Additionally, opportunities for future research are identified.

Observational StudyIncidence of acute compartment syndrome with routine use of regional anesthesia for patients with long bone fractures: a large single-center retrospective review from a level I trauma tertiary academic institution.
Traditionally, using peripheral nerve blocks (PNBs) in patients with long bone fractures has been limited due to concerns that it may interfere with the timely diagnosis of acute compartment syndrome (ACS). However, our large academic institution and level I trauma center have been using regional anesthesia routinely for pain management of patients with long bone fractures for more than a decade, with strict adherence to a comprehensive management protocol. The aim of this retrospective review is to present our experience with this practice. ⋯ Current recommendations on using PNBs in patients at risk for ACS have been mainly based on expert opinion and dated case reports. Due to the nature of the condition, prospective data are lacking. Our large observational dataset evaluated the risk of missing or delaying ACS diagnosis when PNBs were offered for trauma patients and demonstrated a relatively low incidence of ACS despite the routine use of PNBs under strictly protocolized conditions when patients were managed by a dedicated multidisciplinary care team.

Relationship between injectate volume and disposition in erector spinae plane block: a cadaveric study.
Erector spinae plane (ESP) blocks can be used to provide analgesia following thoracoabdominal and lumbar spine surgical procedures. However, the influence of injectate volume and injection location on the spread of anesthetic with ESP blocks remain unclear. ⋯ Increased ESP injection volumes resulted in more extensive cephalocaudal spread, resulting in anesthetic spread to the dorsal rami and ventral ES muscle without involvement of the ventral rami or other anterior structures. Injection volumes of 30 mL may be optimal for ESP blocks requiring analgesia across 4-7 levels.
