The Challenges of Ultrasound-guided Thoracic Paravertebral Blocks in Rib Fracture Patients.

Cureus 2020 Apr 10;12(4):e7626. Epub 2020 Apr 10.

Anesthesiology, Veterans Affairs Puget Sound Health Care System, University of Washington, Seattle, USA.

Thoracic paravertebral blocks (TPVBs) provide an effective pain relief modality in conditions where thoracic epidurals are contraindicated. Historically, TPVBs were placed relying solely on the landmark-based technique, but the availability of ultrasound imaging makes it a valuable and practical tool during the placement of these blocks. TPVBs also provide numerous advantages over thoracic epidurals, namely, minimal hypotension, absence of urinary retention, lack of motor weakness, and remote risk of an epidural hematoma. Read More

Rev Med Liege 2019 Dec;74(12):662-666

Service d'Anesthésie, Centre Hospitalier du Bois de l'Abbaye, Seraing, Belgique.

For about twenty years, peripheral nervous blocks have become the gold standard in postoperative analgesia for knee and foot surgery. The development of echography adapted to anesthesia gave anesthesiologists the opportunity to perform distal, mostly sensitive nerve blocks. Proximal nervous blocks associated analgesia used to be better than general (intravenous or oral) analgesia. Read More

T4 Erector Spinae Plane Block Relieves Postdural Puncture Headache: A Case Report.

Cureus 2019 Nov 26;11(11):e6237. Epub 2019 Nov 26.

Anesthesiology, McGovern Medical School University of Texas Health Science Center, Houston, USA.

Postdural puncture headache (PDPH) is a common complication of neuraxial anesthesia. The gold standard treatment for PDPH is an epidural blood patch (EBP). However, the risks of EBP, and patient willingness to undergo another attempted neuraxial procedure, can prevent patients from receiving this treatment. Read More

Fascia iliaca block, history, technique, and efficacy in clinical practice.

Best Pract Res Clin Anaesthesiol 2019 Dec 26;33(4):407-413. Epub 2019 Jul 26.

Department of Anesthesiology, LSU Health Sciences Center, Room 656, 1542 Tulane Ave., New Orleans, LA 70112, USA. Electronic address:

The facsia iliaca block (FIB) is a relatively new regional technique where local anesthetic is delivered within the fascia iliaca region. Indications for a FIB include surgical anesthesia to the lower extremity after knee, femoral shaft, hip surgery, management of cancer pain or pain secondary to inflammatory conditions of the lumbar plexus, as well as treatment of acute pain in the setting of trauma, fracture, or burns. The FIB may be performed using either a loss of resistance technique or an ultrasound (US)-guided technique; however, the use of US has become commonplace and resulted in improved femoral nerve and obturator nerve motor blocks.

Update on Reversal and Decline of Growth of Utilization of Interventional Techniques In Managing Chronic Pain in the Medicare Population from 2000 to 2018.

Pain Physician 2019 11;22(6):521-536

Massachusetts General Hospital and Harvard Medical School, Boston, MA.

Background: The cost of US health care continues to increase, with treatments related to low back and neck pain and other musculoskeletal disorders accounting for the third highest amount of various disease categories. Interventional techniques for managing pain apart from conservative modalities and surgical interventions, have generally been thought to be growing rapidly. However, a recent analysis of utilization of interventional techniques from 2000 to 2016 has shown a modest decline from 2009 to 2016, compared to 2000 to 2009. Read More

Which Is More Effective for Minimally Invasive Pectus Repair: Epidural or Paravertebral Block?

J Laparoendosc Adv Surg Tech A 2020 Jan 19;30(1):81-86. Epub 2019 Nov 19.

Department of Anesthesiology and Reanimation, Yüksek İhtisas University School of Medicine, Ankara, Turkey.

The aim of this study was to compare the effectiveness of epidural block (EDB) and paravertebral block (PVB) for minimally invasive pectus repair with the conventional method in terms of pain control during and after pectus operations, patient comfort, and length of stay in hospital. A retrospective review was made of patients who underwent minimally invasive pectus repair. The patients were allocated into three groups as follows: PVB group (Pre-emptive ultrasound-guided bilateral thoracic single injection PVB,  = 15); EDB group (Pre-emptive landmark-guided single injection thoracic EDB,  = 8); and Control group (Neither PVB nor EPB,  = 9).

Greater Occipital Nerve Block as a Tool to Diagnose Spontaneous Intracranial Hypotension Before Epidural Blood Patch: A Case Report.

A A Pract 2020 Jan;14(1):6-8

Institute of Anesthesia and Intensive Care, University of Padova, Padova, Italy.

Spontaneous intracranial hypotension (SIH) has been increasingly characterized in recent years. A definitive diagnostic algorithm remains controversial because several symptoms are often found to be nonspecific. When neuroimaging fails to identify a cerebrospinal fluid leak and symptoms are atypical, an epidural blood patch (EBP) may be performed but not without risks. Read More

Influence of injectate volume on paravertebral spread in erector spinae plane block: An endoscopic and anatomical evaluation.

PLoS One 2019 28;14(10):e0224487. Epub 2019 Oct 28.

Department of Anesthesiology and Pain Medicine, Anesthesia and Pain Research Institute, Yonsei University College of Medicine, Seoul, South Korea.

The paravertebral spread that occurs after erector spinae plane block may be volume-dependent. This cadaveric study was undertaken to compare the extent of paravertebral spread with erector spinae plane block using different dye volumes. After randomization, twelve erector spinae plane blocks were performed bilaterally with either 10 ml or 30 ml of dye at the level of T5 in seven unembalmed cadavers except for two cases of unexpected pleural puncture using the 10 ml injection.
