Long-Term Outcomes of Post Dural Puncture Headache Treated With Epidural Blood Patch: A Pilot Study.

Background: Post dural puncture headache (PDPH) is a known complication which may occur in the setting of patients undergoing lumbar punctures (LP) for diagnostic or therapeutic purposes. The gold standard for treating a PDPH is an epidural blood patch (EBP). There have been few publications evaluating the long-term outcomes of PDPH treated with EBP. The aim of this pilot study was to examine the incidence of chronic headaches in dural puncture patients who received EBP versus those who did not. Methods: A retrospective case control study was performed at a single large center institution. Forty-nine patients who had intentional dural puncture were identified on chart review and completed a survey questionnaire via phone interview: twenty-six of these patients required a subsequent EBP, while twenty-three did not. The primary outcomes were the development and prevalence of chronic headaches after the procedures. There was no statistically significant difference in the prevalence of current headaches between the EBP group and Non-EBP group (54% vs. 52% p = 0.91). There were no significant differences in the rates of severity and descriptive qualities of headache between the EBP and non-EBP groups. There was higher incidence of tinnitus in the PDPH patients. Summary: This pilot study demonstrates that patients who received an EBP for treatment of a PDPH following LP are no more likely to experience chronic headaches compared to patients who do not receive an EBP. However, both the EBP group and Non-EBP group had high incidence of chronic headaches which may be related to dural puncture or a baseline trait of this cohort given the recall bias. There is a suggestion that tinnitus could be a long-term residual symptom of PDPH treated with EBP.

Regional Catheters for Outpatient Surgery-a Comprehensive Review.

PURPOSE OF REVIEW: This review summarizes and discusses the history of continuous catheter blockade (CCB), its current applications, clinical considerations, economic benefits, potential complications, patient education, and best practice techniques. RECENT FINDINGS: Regional catheters for outpatient surgery have greatly impacted acute post-operative pain management and recovery. Prior to development, options for acute pain management were limited to the use of opioid pain medications, NSAIDS, neuropathic agents, and the like as local anesthetic duration of action is limited to 4-8 h. Moreover, delivery of opioids post-operatively has been associated with respiratory and central nervous depression, development of opioid use disorder, and many other potential adverse effects. CCB allows for faster recovery time, decreased rates of opioid abuse, and better pain control in patients post-operatively. Outpatient surgical settings continue to focus on efficiency, quality, and safety, including strategies to prevent post-operative nausea, vomiting, and pain. Regional catheters are a valuable tool and help achieve all of the well-established endpoints of enhanced recovery after surgery (ERAS). CCB is growing in popularity with wide indications for a variety of surgeries, and has demonstrated improved patient satisfaction, outcomes, and reductions in many unwanted adverse effects in the outpatient setting.

Pain control in thoracic oncology.

This review of pain management in lung cancer is based on the presentation of four cases of thoracic oncology patients with pain at various stages of their disease. The approach will be multidisciplinary, involving a thoracic oncologist, radiologist, thoracic and orthopaedic spine surgeon, radiation therapist, pain medicine specialist, and palliative care specialist. This multispecialty approach to the management of different painful presentations in thoracic oncology will demonstrate the complexity of each case and the improved patient outcomes which result from the involvement of different disciplines working in concert.In the USA, Europe and other countries, palliative care specialists often become rapidly involved in the management of these patients, coordinating social care and providing psychological support.Thoracic and orthopaedic spine subspecialists provide surgical methods to control tumour invasion, and improve quality of life and preservation of function in settings of even diffuse metastatic disease. Similarly, thoracic oncology and radiation therapists utilise both therapeutic and palliative chemotherapeutic and radiation therapy regimens to prolong and improve quality of life.The pain medicine specialist can, in addition to medication management, offer a variety of interventional approaches including unique drug delivery systems such as epidural analgesia, regional anaesthesia techniques, and intrathecal pumps, as well as neuromodulation techniques and neurolytic or neuroablative procedures.In the USA, these specialists complete an additional fellowship year in pain medicine following the completion of an anaesthesiology, physical medicine and rehabilitation, neurology or psychiatry residency.
