Randomized Controlled TrialEfficacy of the intertransverse process block: single or multiple injection? A randomized, non-inferiority, blinded, cross-over trial in healthy volunteers.
The intertransverse process block is increasingly used to ameliorate postoperative pain following a plethora of surgical procedures involving the thoracic wall. Nevertheless, the optimal approach and cutaneous extent of the sensory block are currently unknown. We aimed to further describe the intertransverse process block, single injection versus multiple injection, and we hypothesized that the single-injection intertransverse process block is a non-inferior technique. ⋯ 2022-501312-34-01.

Opioid tapering after surgery and its association with patient-reported outcomes and behavioral changes: a mixed-methods analysis.
Opioid tapering after surgery is recommended among patients with chronic opioid use, but it is unclear how this process affects their quality of life. The objective of this study was to evaluate how opioid tapering following surgery was associated with patient-reported outcome measures related to pain control and behavioral changes that affect quality of life. ⋯ Partial and complete opioid tapering within 90 days after surgery among patients with chronic opioid use was associated with improved patient-reported measures of pain control as well as behaviors that impact a patient's quality of life.

Hidden risk of gadolinium-based contrast agents during interventional pain medicine procedures: a retrospective chart review.
Epidural steroid injections and epidural blood patches commonly involve the injection of a small amount of radiocontrast media under fluoroscopy to properly identify the target tissue or anatomic space and prevent off-target or intravascular delivery of therapeutic or diagnostic drugs. Iodinated low osmolar non-ionic contrast media is the standard preparation used as it is considered safe and cost-effective, but gadolinium-based preparations have been used as an alternative for patients with an 'iodine'-related or radiocontrast media allergy label to prevent hypersensitivity reactions. The risk of neurotoxic events when gadolinium is inadvertently injected into the intrathecal space has been reported in recent years, raising concerns when gadolinium-based contrast media is used in lieu of iodinated low osmolar non-ionic contrast media. ⋯ Almost all patients in our cohort had an allergy label on their chart that guided the provider to switch to gadolinium-based contrast media, but most were incomplete, ill-defined, or related to allergy to iodine but not iodinated contrast media. Such practice is not recommended based on current guidelines. The current study raises concern regarding the use of gadolinium-based contrast media in axial spine procedures, with the risk of potential severe adverse events, without evidence-based need for avoiding iodinated contrast media.
