ABSTRACT

Advances in our understanding of the biology of spinal systems in organizing and defining the content of exteroceptive information upon which higher centers define the state of the organism and its role in the regulation of somatic and automatic output, defining the motor response of the organism, along with the unique biology and spatial organization of this space, have resulted in an increased focus on therapeutics targeted at this extracranial neuraxial space. Intrathecal (IT) drug delivery systems (IDDS) are well-established as an effective therapeutic approach to patients with chronic non-malignant or malignant pain and as a tool for management of patients with severe spasticity and to deliver therapeutics that address a myriad of spinal pathologies. The risk to benefit ratio of IDD makes it a useful interventional approach. While not without risks, this approach has a significant therapeutic safety margin when employed using drugs with a validated safety profile and by skilled practioners. The present review addresses current advances in our understanding of the biology and dynamics of the intrathecal space, therapeutic platforms, novel therapeutics, delivery technology, issues of safety and rational implementation of its therapy, with a particular emphasis upon the management of pain.

ABSTRACT

The combined use of a double-lumen tube and a bronchial blocker can be very helpful in two different clinical scenarios: (1) in isolating not only the contralateral lung, but also the lobe/s of the same lung in which the infected lobe must be resected, (2) in preventing/treating hypoxemia because of the presence of a contralateral lobectomy. A cardiothoracic anesthesiologist must expertise this technique to avoid complications during surgery.

ABSTRACT

The adjacent segment syndrome is defined as the changes in the adjacent structures of an operated spinal level that produce symptoms of pain and disability, which worsen the quality of life of a patient. Pain management specialists must be aware of these biomechanical changes brought by spinal surgeries, as well as of the symptoms associated with pain after surgery, to reach an appropriate diagnosis and provide an adequate treatment. Specialized pain literature contains few reports on specific management of patients using the terms "adjacent segment syndrome, degeneration or disease;" most of the literature comes from surgical journals. It is necessary to perform studies with a population sample comprising patients with adjacent segment syndrome after spinal surgery, since almost all treatments applied in this group are extrapolated from those used in patients with pain originating in the same area but who have not previously undergone spine surgery. Therefore, we consider necessary for pain physicians to understand the underlying biomechanics, promote the diagnosis of this condition, and analyze possible treatments in patients with adjacent segment disease to alleviate their pain and improve their quality of life.

ABSTRACT

Electrode migration is a challenge, even with adequate anchoring techniques, due to the high mechanical stress on components of occipital nerve stimulation (ONS) for headache disorders. When a lead displacement of an ONS implant is diagnosed, there are currently different approaches described for its management. Nevertheless current neuromodulation devices are designed like a continuum of components without any intermediate connector, and if a lead displacement is diagnosed, the solution is the complete removal of the electrode from its placement, and its repositioning through an ex-novo procedure. The described technique can allow ONS leads to be revised while minimizing the need to reopen incisions over the IPG, thus improving patients' intraoperative and postoperative discomfort, shortening surgical time and medical costs, reasonably reducing the incidence of infective postoperative complications.

ABSTRACT

Targeted intrathecal (IT) drug delivery systems (IDDS) are well established as an effective treatment of patients with chronic nonmalignant or malignant pain, and as a tool for management of patients with severe spasticity. The risk to benefit ratio of IDD makes it a relatively safe therapy for both cancer- and noncancer-related pain, but it is not free of risks, so it should be managed at specific centers. Recent technological advances, new therapeutic applications, reported complications, and the costs as well as maintenance required for this therapy require the need to stay up to date about new recommendations that may improve outcomes. This chapter reviews all technological issues regarding IDDS implantation with follow-up and pharmacological recommendations published during recent years that provide evidence-based decision-making process in the management of chronic pain and spasticity in patients.

ABSTRACT

This chapter describes the microanatomy of the spinal cord that is relevant to intrathecal drug delivery started with covering of the spinal cord that are pierced to enter the intrathecal space. The dural sac is mostly constituted by the outer layer of dura and the inner layer called arachnoid membrane, which regulates diffusion of drugs into the intrathecal space. The pia matter surrounding the spinal cord is a permeable structure allowing the passage of drugs through intercellular spaces. The relationship between nerve roots, CSF, and subarachnoid catheters determines the passage of an intrathecal catheter which can cause damage to nerve roots and spinal cord. Multiple factors may be involved in the mechanisms of drug diffusion across the membranes of the spinal cord, as well as in their dilution with the CSF, which will lead to the final drug distribution and availability at nerve roots and the spinal cord.

ABSTRACT

Controlling pain should be a priority in the clinical practice of intensive care units (ICUs). Monomodal analgesic approaches, such as the administration of opioids, are widely employed; however, the widespread use of opioids has catastrophic consequences, given their multiple side effects and the development of dependence. Regional analgesia (RA), with single or continuous dosing using neuraxial and peripheral catheters, can play an important role in multimodal analgesia for management of pain in critical care patients. RA provides superior pain control, as compared to systemic treatments, and is associated with a lower rate of side effects. Nevertheless, RA remains underused in ICUs. Many critically ill, post-surgical or traumatically injured patients would benefit from these techniques. For these reasons, we aim to establish a set of potential indications integrating the use of RA in analgesia protocols routinely used in ICUs. We performed a review of literature sources with contrasted evidence levels to present RA techniques and their potential applications in ICU patients.
