Regional anesthesia and pain medicine

Globally, non-steroidal anti-inflammatory drugs (NSAIDs) are highly used to treat pain. With the rise of the COVID-19 pandemic, the safety of NSAIDs use has been called into question. ⋯ At present, there is no compelling data showing that NSAIDs worsen the severity of COVID-19 symptoms or increase one's likelihood of contracting the illness. For patients in pain and without symptoms that could potentially be attributed to COVID-19 (cough, fevers/chills, lethargy, myalgias, anosmia and so on), NSAIDs should continue to remain a viable option to provide analgesia to patients in need.

Case ReportsSuccessful transforaminal epidural blood patch in a patient with multilevel spinal fusion.
Epidural blood patch (EBP) is a vital tool in treating postdural puncture headache (PDPH). Traditional interlaminar epidural needle insertion into the epidural space, however, may be challenging due to anatomical variations. As an alternative method, we successfully performed an EBP via transforaminal approach. ⋯ To our knowledge, this is the first case reported of a transforaminal EBP in a patient with diffuse epidural adhesive fibrosis secondary to multilevel laminectomies and spinal fusion. This case report highlights potential risks and benefits of this novel technique and also discusses its therapeutic mechanism of action. We believe that a transforaminal EBP should be considered in patients who are poor candidates for the traditional interlaminar EBP.

Ultrasound detection of iatrogenic injury during peribulbar eye block: a cadaveric study.
Ophthalmic eye blocks, such as retrobulbar, peribulbar and sub-Tenon's, are traditionally conducted "blind". Complications are rare but potentially devastating. Life-threatening complications include brain stem anesthesia and local anesthetic toxicity, whereas sight-threatening complications include globe perforation, optic nerve damage and ocular muscle damage. Ultrasound permits a view of orbital structures and can be used to guide needle placement. The ultrasound appearances of unintended local anesthetic injection into vital orbital structures have not been documented. This study aimed to record the ultrasound appearances of unintended injection locations. ⋯ The ultrasound appearance of block complications is important to document and should be an integral part of regional anesthesia training. This study is the first to provide such images for ophthalmic nerve blocks. It offers ophthalmic anesthetists and ophthalmologists the potential to diagnose severe complications rapidly and accurately with a potential impact on patient safety.
