Case Reports
Intrathecal catheter-syringe adaptor for short-term intrathecal analgesia with an externalized pump: a case report.
In most patients, cancer pain is effectively treated with conservative medical management consisting of oral and/or transdermal analgesics. Cancer patients tend to fail conservative medical management near the end of their life expectancy, thus requiring alternative routes of analgesia such as intravenous, epidural, or intrathecal. The intrathecal route provides the most effective analgesia due to the close proximity of the opioid receptors in the spinal cord. Though there are many techniques that exist for intrathecal drug delivery, complications can limit effectiveness such as infection, bleeding, cerebrospinal fluid (CSF) leaks, post-dural puncture headaches (PDPH), pump and/or catheter malfunctions, or limitations of technical expertise. Therefore, an important goal in palliative cancer pain therapy is to use equipment that is going to have the fewest number of complications and will be the most familiar to the health care providers. We describe the combination of the Medtronic Indura 1P catheter, which has the least catheter-related complications and can be used with any external drug infusion pump. These are regular infusion pumps that the health care workers are familiar with so they can provide excellent and efficient service to the patient. ⋯ This technique is simple to perform by pain specialists. The catheter modification allows the use of the Medtronic intrathecal catheter with standard external drug infusion pumps. This facilitates the patient's care in the hospice setting.

Nucleoplasty is a minimally invasive procedure for treating pain caused by symptomatic disc herniation that is refractory to conservative therapy. Observational studies have reported differing outcomes for this procedure and thus its effectiveness is yet to be determined. ⋯ Observational studies suggest that nucleoplasty is a potentially effective minimally invasive treatment for patients with symptomatic disc herniations who are refractory to conservative therapy. The recommendation is a level 1C, strongly supporting the therapeutic efficacy of this procedure. However, prospective randomized controlled trials with higher quality of evidence are necessary to confirm efficacy and risks, and to determine ideal patient selection for this procedure.

Intracranial neurostimulation for pain relief is most frequently delivered by stimulating the motor cortex, the sensory thalamus, or the periaqueductal and periventricular gray matter. The stimulation of these sites through MCS (motor cortex stimulation) and DBS (deep brain stimulation) has proven effective for treating a number of neuropathic and nociceptive pain states that are not responsive or amenable to other therapies or types of neurostimulation. Prospective randomized clinical trials to confirm the efficacy of these intracranial therapies have not been published. ⋯ DBS may be employed for a number of nociceptive and neuropathic pain states, including cluster headaches, chronic low back pain, failed back surgery syndrome, peripheral neuropathic pain, facial deafferentation pain, and pain that is secondary to brachial plexus avulsion. The unique lack of stimulation-induced perceptual experience with MCS makes MCS uniquely suited for blinded studies of its effectiveness. This article will review the scientific rationale, indications, surgical techniques, and outcomes of intracranial neuromodulation procedures for the treatment of chronic pain.

The health care industry in general and care of chronic pain in particular are described as recession-proof. However, a perfect storm with a confluence of many factors and events -none of which alone is particularly devastating - is brewing and may create a catastrophic force, even in a small specialty such as interventional pain management. Multiple challenges related to interventional pain management in the current decade will include individual and group physicians, office practices, ambulatory surgery centers (ASCs), and hospital outpatient departments (HOPD). ⋯ There is focus on avoiding waste, abuse, fraud, and also cutting costs. Evidence-based medicine (EBM) and comparative effectiveness research (CER) have been introduced as cost-cutting and rationing measures, however, with biased approaches. This manuscript will analyze various issues related to interventional pain management with a critical analysis of physician payments, office facility payments, and ASC payments by various payor groups.

Interventional pain management now stands at the crossroads at what is described as "the perfect storm." The confluence of several factors has led to devastating results for interventional pain management. This article seeks to provide a perspective to various issues producing conditions conducive to creating a "perfect storm" such as use and abuse of interventional pain management techniques, and in the same context, use and abuse of various non-interventional techniques. The rapid increase in opioid drug prescribing, costs to health care, large increases in death rates, and random and rampant drug testing, can also lead to increases in health care utilization. ⋯ Based on the results of this review, various issues of relevance to modern interventional pain management are discussed and the viewpoints of several experts debated. In conclusion, supporters of interventional pain management disagree on multiple aspects for various reasons while detractors claim that interventional pain management should not exist as a speciality. Issues to be addressed include appropriate use of evidence-based medicine (EBM), overuse, overutilization, and abuse.
