BACKGROUND: The plantaris tendon (PT) has been implicated in the pathogenesis of symptoms in a subset of patients with Achilles region pain syndromes and has been traditionally managed via open surgical resection. Although the PT can be visualized on ultrasound, a minimally invasive technique for sonographically guided PT release has not been formally described. OBJECTIVE: To validate a technique to perform sonographically guided PT release in an unembalmed cadaveric model...

BACKGROUND AND OBJECTIVES: For superficial surgery of anteromedial and posteromedial surfaces of the upper arm, the medial brachial cutaneous nerve (MBCN) and the intercostobrachial nerve (ICBN) must be selectively blocked, in addition to an axillary brachial plexus block. We compared efficacy of ultrasound-guided (USG) versus conventional block of the MBCN and the ICBN. METHODS: Eighty-four patients, undergoing upper limb surgery, were randomized to receive either USG (n = 42) or conventional (n = 42) block of the MBCN and the ICBN with 1% mepivacaine...

Fentanyl is a potent synthetic opioid used as a narcotic analgesic supplement in general and regional anesthesia as well as in management of persistent, severe chronic pain. Alarming epidemiological and forensic medicine reports, accumulated mainly during the last two decades, point to a growing increase in illicit use of fentanyl, mainly in North America and Europe. Toxicological data indicates that fentanyl use is inextricably linked with polydrug use. There are two main sources of fentanyl on the "recreational" drug market...

Qi Chen, Ran An, Ju Zhou, Bin Yang
BACKGROUND: Perineural dexamethasone has been shown to prolong the duration of local anesthetic (LA) effect in regional anesthesia; however, the use of perineural dexamethasone as an adjuvant to to the transversus abdominis plane (TAP) block remains controversial. This meta-analysis sought to assess the efficacy of dexamethasone in prolonging the TAP block and enhancing recovery after abdominal surgery. METHODS: We identified and analyzed 9 RCTs published on or before September 30, 2017, regardless of the original language, after searching the following 6 bibliographic databases: PubMed, EMBASE, Medline, Springer, Ovid, and the Cochrane Library...

BACKGROUND: Preeclampsia is among the most common medical complications of pregnancy. The clinical utility of invasive hemodynamic monitoring in preeclampsia (e.g., Swan-Ganz catheter) is controversial. Thoracic impedance cardiography (TIC) and Doppler echocardiography are noninvasive techniques but they both have important limitations. NICaS™ (NI Medical, PetachTikva, Israel) is a noninvasive cardiac system for determining cardiac output (CO) that utilizes regional impedance cardiography (RIC) by noninvasively measuring the impedance signal in the periphery...

Resham Datta, Jason K Panchamia
Systemic capillary leak syndrome (SCLS) is an idiopathic vascular hyperpermeability that leads to profound hypotension, hypoalbuminemia, and hemoconcentration. Sixty years since its inauguration into literature, SCLS is still elusive, underdiagnosed, and profoundly dangerous. Few authors have documented anesthetic implications of classical acute SCLS, a form with complete recovery between exacerbations. However, minimal information is available about chronic SCLS, continuous generalized edema with or without exacerbations...

We report the case of a 21-year-old primiparous woman at 22 weeks gestation who presented with a large uncorrected ventricular septal defect, severe pulmonary hypertension, and Eisenmenger syndrome. The patient elected for termination of pregnancy, which was performed under regional anesthesia. Hemodynamic changes apparently associated with uterine contraction immediately after termination resulted in increased right to left shunting across the ventricular septal defect requiring urgent venovenous extracorporeal membrane oxygenation...

Severely atrophic mandible fractures are frequently a challenge to treat. Virtual surgical planning (VSP) uses three-dimensional computed tomographic (CT) scans that can be translated into stereolithographic models to fabricate surgical templates, facilitating intraoperative procedures. The purpose of this article is to describe the reconstruction of two cases of severe atrophic mandible fracture using VSP. Two elderly edentulous/partially dentate patients who presented with fractures of their mandibles and who underwent reconstruction using VSP were included...

BACKGROUND: Two-thirds of the world's population lack access to safe anesthesia and surgical care. Nongovernmental organizations (NGOs) play an important role in bridging the gap, but surgical outcomes vary. After complex surgeries, up to 20-fold higher postoperative complication rates are reported and the reasons for poor outcomes are undefined. Little is known concerning the incidence of anesthesia complications. Mercy Ships uses fully trained staff, and infrastructure and equipment resources similar to that of high-income countries, allowing the influence of these factors to be disentangled from patient factors when evaluating anesthesia and surgical outcomes after NGO sponsored surgery...

Introduction: Neuraxial labor analgesia has become an integral part of modern obstetric anesthetic practice. Presence of a familiar person during its placement may be beneficial to the patient. A survey was sent to anesthesiologists practicing obstetric anesthesia in the USA to determine their views. Methods: The survey queried the following: existence of a written policy; would they allow a visitor; visitor's view, sitting or standing; reasons to allow or not allow a visitor; and influence by other staff on the decision...

INTRODUCTION: Local anesthetic infiltration is used widely for post-operative analgesia in many situations. However the effects of local anesthetics on wound healing are not demonstrated clearly. This study planned to evaluate the effects of lidocaine, prilocaine, bupivacaine and levobupivacaine on wound healing, primarily on wound tensile strength and on collagen ultrastructure. METHODS: This study was conducted on male Sprague Dawley rats. On days 0, 8th, 15th, and 21st, all animals were weighed and received a preincisional subcutaneous infiltration of 3mL of a solution according the group...

BACKGROUND: Over the past 2 decades, the use of intravenous ketamine infusions as a treatment for chronic pain has increased dramatically, with wide variation in patient selection, dosing, and monitoring. This has led to a chorus of calls from various sources for the development of consensus guidelines. METHODS: In November 2016, the charge for developing consensus guidelines was approved by the boards of directors of the American Society of Regional Anesthesia and Pain Medicine and, shortly thereafter, the American Academy of Pain Medicine...

BACKGROUND: Ketamine infusions have been used for decades to treat acute pain, but a recent surge in usage has made the infusions a mainstay of treatment in emergency departments, in the perioperative period in individuals with refractory pain, and in opioid-tolerant patients. The widespread variability in patient selection, treatment parameters, and monitoring indicates a need for the creation of consensus guidelines. METHODS: The development of acute pain ketamine guidelines grew as a corollary from the genesis of chronic pain ketamine guidelines...
