#1
T Apard, G Candelier
The central slip tenotomy described by Fowler is an effective option for treating chronic mallet finger in order to avoid swan neck deformity of the finger. In a prospective study of 14 cases (13 failures of conservative treatment and one case of untreated mallet finger), we performed percutaneous ultrasound-guided central slip tenotomy with a 19 G needle using the wide-awake local anesthesia and no tourniquet (WALANT) technique. The mean extensor lag before surgery was 28° (range 20°-40°) and three patients had a swan neck deformity...

PURPOSE: Epidural and spinal needle insertions, as well as facet joint denervation and injections are widely performed procedures on the lumbar spine for delivering anesthesia and analgesia. Ultrasound (US)-based approaches have gained popularity for accurate needle placement, as they use a non-ionizing, inexpensive and accessible modality for guiding these procedures. However, due to the inherent difficulties in interpreting spinal US, they yet to become the clinical standard-of-care...

BACKGROUND: The quest for an ideal sedative during regional anesthesia is on. Although propofol has been accepted as a sedative intraoperatively, it can be associated with troublesome hemodynamic changes. Dexmedetomidine is a new alpha 2 agonist used widely for sedation. AIMS: In this study, we tried to compare equivalent doses of dexmedetomidine infusion with propofol with emphasis on their effect on the hemodynamics. SETTINGS AND DESIGN: Prospective, single-blinded randomized controlled trial...

Ultrasound-guided regional anesthesia (UGRA), like other basic skills, should be learnt in a simulation laboratory before performing on the patient. Cadavers provide an ideal tool for learning sonoanatomy and skills required for performing UGRA. On the basis of preservation technique used, the cadavers can be formalin embalmed cadavers, Thiel cadavers (soft cadavers), and fresh frozen cadavers. We compared three types of cadavers for performing ultrasound-guided upper and lower limb blocks. We observed that fresh frozen and Thiel cadavers were less smelling and had more realistic appearance as compared to formalin embalmed cadavers...

PURPOSE OF REVIEW: The current review considers an array of recent applications for point-of-care ultrasound in clinical practice including diagnostic and therapeutic procedures that may be relevant for the obstetric anesthesiologist. The rapid advancement of technology and clinical applications for bedside ultrasound in obstetric anesthesiology requires an appraisal of the limitations and uses. RECENT FINDINGS: The review presents the most recent literature describing ultrasound-guided airway assessments, airway management, cricothyroidotomy, transthoracic echocardiography, gastric volume assessments, point-of-care lung ultrasound diagnoses, intracranial pressure assessments, vascular access, neuraxial blocks, and transversus abdominis plane blocks...

OBJECTIVE: Our objective was to describe the first reported use of an axillary brachial plexus block to treat the entrapment of a transradial artery catheter due to vasospasm. CASE REPORT: A 42-year-old man undergoing transradial arterial cardiac catheterization suffered arterial vasospasm causing the catheter to become entrapped and refractory to conservative (warm compresses) and standard pharmacologic interventions (intracatheter verapamil, intravenous infusions of nitroglycerin and nicardipine, and subcutaneous lidocaine and topical nitroglycerin)...

PURPOSE OF REVIEW: With the increasing number of ambulatory surgeries being performed, regional anesthesia has become an increasingly popular anesthetic modality, and many choices exist to provide efficient, effective quality perioperative analgesia. In this paper, we will review the various regional anesthesia options in addition to the advantages and disadvantages of each. Lastly, we will discuss liposomal bupivicaine, a long acting local anesthetic, and its future role in the anesthesiologist's armamentarium...

A fully-automatic ultrasound image processing system that can determine the needle entry site for epidural anesthesia (EA) in real time is presented in this paper. Neither the knowledge of anesthetists nor additional hardware is required to operate the system, which firstly directs the anesthetists to reach the desired insertion region in the longitudinal view, i.e., lumbar level L3-L4, and then locates the ideal puncture site by instructing the anesthetists to rotate and slightly adjust the position of ultrasound probe...

BACKGROUND: Isolated congenital diaphragmatic hernia (CDH) defect allows viscera to herniate into the chest, competing for space with the developing lungs. At birth, pulmonary hypoplasia leads to respiratory insufficiency and persistent pulmonary hypertension that is lethal in up to 30% of patients. Antenatal measurement of lung size and liver herniation can predict survival after birth. Prenatal intervention aims at stimulating lung development, clinically achieved by percutaneous fetal endoscopic tracheal occlusion (FETO) under local anesthesia...

Surgery of the wrist and hand commonly involves regional anesthesia of the median nerve and superficial radial nerve within the forearm. In this sonographic study, the contribution of the lateral cutaneous nerve of forearm (LCNF) to thumb cutaneous sensation was studied. Patients scheduled for thumb suspension arthroplasty (n = 35) were examined by ultrasound, with LCNF, median nerve, and superficial radial nerve identified. A single nerve was then injected with local anesthetic, and the area of cutaneous sensory loss mapped at 15 minutes...

Claire Lyons, Andrew A Herring
Deltoid abscesses are common and painful, often a consequence of injection drug use and seen frequently in emergency departments (EDs). The required incision and drainage can be completed successfully with effective pain relief using a peripheral nerve block. The brachial plexus nerve block works well, however it is technically complex with a low, but potentially serious, risk of complications such as phrenic nerve paralysis. Selective blockade of the axillary nerve eliminates the risks associated with a brachial plexus block, while providing more specific anesthesia for the deltoid region...

BACKGROUND AND OBJECTIVES: The interscalene brachial plexus block (ISB), a potent option to control pain after shoulder surgery, has notable adverse effects. The anterior suprascapular nerve block (SSNB) might provide comparable analgesia and cause less grip-strength impairment. These characteristics were studied in this randomized controlled patient- and assessor-blinded trial. METHODS: Outpatients were randomized to single-shot ultrasound-guided SSNB (10 mL ropivacaine 1%) or ISB (20 mL ropivacaine 0...

OBJECTIVE: To report a case of successful surgical removal of a guide wire lost during central venous catheterization. CASE SUMMARY: A 28 kg, 4-year-old female neutered mixed breed dog presented to the primary care veterinarian with diabetic ketosis. During the process of central venous catheterization, the guide wire was accidently released and the entire length of the guide wire slipped into the jugular vein. Due to the absence of nearby interventional radiology facilities, surgical intervention was proposed...
