Clinical Trial
A prospective evaluation of bleeding risk of interventional techniques in chronic pain.
The role of antithrombotic therapy is well known for primary and secondary prevention of cardiovascular disease to decrease the incidence of acute cerebral and cardiovascular events. Data shows that the risk of coronary thrombosis after antiplatelet drug withdrawal is much higher than that of surgical bleeding if the antiplatelet drug therapy were continued. However, it has been a common practice to discontinue antiplatelet therapy prior to performing interventional techniques, which may potentially increase the risk of acute cerebral and cardiovascular events. ⋯ No significant prevalence of adverse events was observed in those who continued with or ceased antithrombotic therapy.

The traditional superoanterior approach for transforaminal epidural steroid injection (TFESI) carries a risk of complication by obstructing arterial flow to the anterior portion of the spinal cord by puncturing the spinal radicular artery that passes through the superoanterior foraminal zone or "safe triangle" zone, which does not describe vascular safety, but rather describes neural safety. Consequently, multiple disasters have been described in recent years with transforaminal epidural injections. ⋯ Multiple different techniques have been discussed and described in recent years, the majority of them to avoid the radicular artery injection. The primary goal of this paper is to describe another posterior approach to place the tip of spinal needle directly toward the posterior epidural space to avoid puncturing the spinal radicular artery and minimize nerve root penetrations while delivering medication into the epidural space through the foramen.

Multicenter Study Clinical Trial
Improving the safety of transforaminal epidural steroid injections in the treatment of cervical radiculopathy.
Unplanned vascular trespass occurs in 20% of cervical transforaminal epidural steroid injections (CTFESI) and rarely results in devastating neurologic complications. The Trucath Spinal Injection System is a novel integrated catheter and needle device that is specifically designed to minimize vascular trespass risk. ⋯ The Trucath Spinal Injection System demonstrated a statistically significant reduction in the rate of intravenous and intra-arterial trespass, procedural pain, and paresthesia, and has similar accuracy and performance versus standard spinal needles for CTFESI treatment of cervical radiculopathy.

Practice Guideline Meta Analysis
Comprehensive consensus based guidelines on intrathecal drug delivery systems in the treatment of pain caused by cancer pain.
Chronic persistent pain as a result of terminal illness, either as a consequence of the disease or the necessary treatment, is common in patients with cancer. For these patients with moderate-to-severe intractable pain, intrathecal (IT) drug delivery systems may represent an effective option for pain management. Thus, IT drug delivery is a viable treatment strategy for both neuropathy and nociceptive pain in the cancer population. However, there is a scarcity of comprehensive guidelines in implanting IT drug delivery systems in the treatment of pain caused by cancer. ⋯ These consensus guidelines are intended to assist clinicians in identifying the candidacy of patients with cancer-related pain and end of life diseases causing pain that may benefit from intrathecal drug delivery. With careful consideration of the patient's medical comorbidities and prior therapies, communication with the oncologist, proper psychological evaluation, and appropriate trialing technique, clinicians can effectively optimize the use of IT therapy for cancer pain. The panel advocates for a much wider application of IT therapy to provide meaningful analgesia for patients with cancer pain, including those at the end of life from a variety of causes.

Intrathecal drug infusion therapy is usually considered when spinal-acting analgesics or antispasmodics administered via the oral or transdermal routes fail to control patients' pain or are associated with unacceptable side effects. The intrathecal administration of centrally acting agents bypasses the blood-brain-barrier resulting in much higher cerebrospinal fluid (CSF) concentrations while using reduced amounts of medication to achieve equipotent doses. The intrathecal approach is associated with higher rates of satisfactory pain relief and lower rates of treatment failures and technical complications compared to the epidural route. A paucity of randomized controlled trials (RCTs) has led to concern regarding proper use, selection criteria, and safety of these devices. Cost effectiveness and comparative therapies have now also become a focus of discussion. ⋯ Based on the available evidence, the recommendation for intrathecal infusion systems for cancer-related pain is moderate recommendation based on the high quality of evidence and the recommendation is limited to moderate based on the moderate quality of evidence from non-randomized studies for non-cancer related pain.
