The PECS II nerve block is a relatively new regional anesthetic technique that targets the medial and lateral pectoral nerves, as well as the lateral cutaneous branches of the intercostal nerves. It has been described for surgical cases involving the breast, as an adjunct or alternative to neuraxial or paravertebral techniques. This case report describes the first successful use of the PECS II nerve block placed using ultrasound guidance as the primary anesthetic and postoperative analgesic in a non-breast-related chest wall surgery...

Nerve blocks are frequently performed by anesthesiologists to control pain. For sciatic nerve blocks, the optimal placement of the needle tip between its paraneural sheath and epineurial covering is challenging, even under ultrasound guidance, and frequently results in nerve puncture. We performed needle penetration tests on cadaveric isolated paraneural sheath (IPS), isolated nerve (IN), and the nerve with overlying paraneural sheath (NPS), and quantified puncture force requirement and fracture toughness of these specimens to assess their role in determining the clinical risk of nerve puncture...

Background: The supraclavicular approach is considered to be the easiest and most effective approach to block the brachial plexus for upper limb surgeries. The classical approach using the anatomical landmark technique was associated with higher failure rates and complications. Ultrasonography (USG) guidance and peripheral nerve stimulator (PNS) have improved the success rates and safety margin. Aims: The aim of the present study is to compare USG with PNS in supraclavicular brachial plexus block for upper limb surgeries with respect to the onset of motor and sensory blockade, total duration of blockade, procedure time, and complications...

BACKGROUND: Many clinicians require a solid understanding of the anatomical areas supplied by specific peripheral nerves. Virtually all pertinent medical textbooks claim that the entire (palmar and dorsal) surface of the hand is supplied by three (median, radial, and ulnar) nerves and that each of these covers a well-defined area. This study was designed to evaluate the sensory-distribution pattern of peripheral nerves in the hand. METHODS: Twelve volunteers were enrolled and randomly allocated to have median, ulnar, or radial nerve blocks to each hand on three successive days...

Chronic pain is a common medical condition. Patients who suffer uncontrolled chronic pain may require interventions including spinal injections and various nerve blocks. Interventional procedures have evolved and improved over time since epidural injection was first introduced for low back pain and sciatica in 1901. One of the major contributors in the improvement of these interventions is the advancement of imaging guidance technologies. The utilization of image guidance has dramatically improved the accuracy and safety of these interventions...

BACKGROUND: Peripheral nerve blocks (PNBs) provide excellent pain control and reduce the need for systemic analgesics in orthopaedic surgery. PNBs rarely cause complications; however, a few studies of adults have reported neurological complications during the early postoperative period. We investigated complications associated with the use of PNBs during pediatric knee surgery. METHODS: We reviewed the medical records of all 121 children (aged ≤18 y) who underwent knee surgery by 1 orthopaedic surgeon between October 2014 and September 2016...

Elderly patients with hip fracture experience high morbidity and mortality, and are often undertreated for pain. Acute pain management in the elderly is challenging, with physiological frailty, medical comorbidities and cognitive impairment commonly compounding pain assessment and treatment. Guidelines outlining current best practice for acute pain management in the elderly now exist, but evidence suggests that practice remains variable and there continues to be scope for improvement. We conducted a narrative review of the literature to examine the challenges of acute pain management in the elderly, and to evaluate evidence for the role of regional nerve blocks for acute pain associated with hip fracture in the elderly...
