ReviewAnalgesic Techniques for Rib Fractures-A Comprehensive Review Article.
Rib fractures are a common traumatic injury that has been traditionally treated with systemic opioids and non-opioid analgesics. Due to the adverse effects of opioid analgesics, regional anesthesia techniques have become an increasingly promising alternative. This review article aims to explore the efficacy, safety, and constraints of medical management and regional anesthesia techniques in alleviating pain related to rib fractures. ⋯ Recently, opioid analgesia, thoracic epidural analgesia (TEA), and paravertebral block (PVB) have been favored options in the pain management of rib fractures. TEA has positive analgesic effects, and many studies vouch for its efficacy; however, it is contraindicated for many patients. PVB is a viable alternative to those with contraindications to TEA and exhibits promising outcomes compared to other regional anesthesia techniques; however, a failure rate of up to 10% and adverse complications challenge its administration in trauma settings. Serratus anterior plane blocks (SAPB) and erector spinae blocks (ESPB) serve as practical alternatives to TEA or PVB with lower incidences of adverse effects while exhibiting similar levels of analgesia. ESPB can be performed by trained emergency physicians, making it a feasible procedure to perform that is low-risk and efficient in pain management. Compared to the other techniques, intercostal nerve block (ICNB) had less analgesic impact and required concurrent intravenous medication to achieve comparable outcomes to the other blocks. The regional anesthesia techniques showed great success in improving pain scores and expediting recovery in many patients. However, choosing the optimal technique may not be so clear and will depend on the patient's case and the team's preferences. The peripheral nerve blocks have impressive potential in the future and may very well surpass neuraxial techniques; however, further research is needed to prove their efficacy and weaknesses.

Critical limb ischemia (CLI) is limb pain occurring at rest or impending limb loss as a result of lack of blood flow to the affected extremity. CLI pain is challenging to control despite multimodal pharmacologic analgesia and surgical intervention. ⋯ Her opioid requirements tailed down subsequently with the successful insertion of the infraclavicular nerve catheter and she remained pain free till her death. Palliative use of nerve catheters is a safe and an effective alternative in patients with refractory cancer pain, and we describe our methods to prolong its use and minimizing its associated long-term complications.

Chronic opioid therapy may lead to high level tolerance development, hyperalgesia, and central sensitization, which further complicates long-term therapeutic management of chronic pain patients. In this case, we encounter a patient who was receiving over 15,000 morphine milligram equivalents through their intrathecal pain pump. Unfortunately, the intrathecal pump was inadvertently cut during a spinal surgery. It was deemed unsafe to delivery IV equivalent opioid therapy in this case; instead, the patient was admitted to the ICU and given a four-day ketamine infusion. ⋯ Ketamine may play an important role in attenuating not only tolerance but also acute withdrawal in a setting where rapid or instant weaning from high dose chronic opioid therapy is needed.

The need of a comprehensive approach in a condition of poorly opioid-responsive cancer pain.
Spinal analgesia is often claimed as an effective strategy for patients with a poor response to systemic opioids. Despite the optimistic data reported in literature with intrathecal drug delivery systems (IDDS) for cancer pain, a critical analysis showed modest benefit. Indeed, intrathecal therapy may be potent means to be used in a very selected population. However, ability to manage spinal therapy combined with the use of opioids and other drugs in the general perspective of a comprehensive palliative care treatment may allow to resolve refractory cancer pain in a patient with a clinical profile of poor pain prognosis, according to the Edmonton staging system. ⋯ No evidence-based treatment can be taken into consideration for such extreme conditions, where only experience and knowledge can guide to an effective course of treatment along a period of about six months. Timely therapeutic strategies are needed to be performed in each challenging clinical situation along the course of disease.
