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...

BACKGROUND AND OBJECTIVES: Dosage of local anesthetics (LAs) used for regional anesthesia in children is not well determined. In order to evaluate and come to a consensus regarding some of these controversial topics, The European Society of Regional Anaesthesia and Pain Therapy (ESRA) and the American Society of Regional Anesthesia and Pain Medicine (ASRA) developed a Joint Committee Practice Advisory on Local Anesthetics and Adjuvants Dosage in Pediatric Regional Anesthesia. METHODS: Representatives from both ASRA and ESRA composed the joint committee practice advisory...

Marina Gitman, Michael J Barrington
This review summarizes presenting features, management, and outcomes of local anesthetic systemic toxicity (LAST) from published cases and those submitted to online registries capturing use of intravenous lipid emulsion (ILE) therapy. The results of single-center and multicenter registries and epidemiologic studies complement this information. Between March 2014 and November 2016, 47 separate cases of LAST were described in 35 peer-reviewed articles. Local anesthetic systemic toxicity events occurred as a result of penile blocks (23%), local infiltration (17%), and upper/lower extremity, torso, and neuraxial blockade...

BACKGROUND: Local anesthetic systemic toxicity (LAST) is a rare and potentially devastating complication of regional anesthesia. Single-institution registries have reported a decreasing incidence, but these results have limited broad applicability. A recent study using a US database found a relatively high incidence of LAST. We used the National Inpatient Sample, a US database of inpatient admissions, to identify the national incidence and associated risk factors for LAST in total joint arthroplasties...

BACKGROUND: Clinical and experimental data show that peripheral nerve blocks last longer in the presence of diabetic neuropathy. This may occur because diabetic nerve fibers are more sensitive to local anesthetics or because the local anesthetic concentration decreases more slowly in the diabetic nerve. The aim of this study was to investigate both hypotheses in a rodent model of neuropathy secondary to type 2 diabetes. METHODS: We performed a series of sciatic nerve block experiments in 25 Zucker Diabetic Fatty rats aged 20 weeks with a neuropathy component confirmed by neurophysiology and control rats...

BACKGROUND: Nontraumatic lower extremity amputation (LEA) remains a common procedure among patients who frequently have significant comorbidities. Patients undergoing above knee amputation (AKA) have the highest rates of mortality in this cohort, yet there is little evidence to support selection between peripheral nerve block or neuraxial regional anesthesia (RA) versus general anesthesia (GA) techniques. The objective of this study was to determine whether RA (neuraxial or peripheral nerve block) techniques were associated with more favorable outcomes versus general anesthesia among patients undergoing AKA...

Here we describe methods for creating tissue-mimicking ultrasound phantoms based on patient anatomy using a soft material called gel wax. To recreate acoustically realistic tissue properties, two additives to gel wax were considered: paraffin wax to increase acoustic attenuation, and solid glass spheres to increase backscattering. The frequency dependence of ultrasound attenuation was well described with a power law over the measured range of 3-10 MHz. With the addition of paraffin wax in concentrations of 0 to 8 w/w%, attenuation varied from 0...

BACKGROUND: Anesthetic block of the peripheral nerves in the foot and ankle is generally used as anesthesia. The increased use of anesthetic blocks has made this technique an increasingly safe method, and its use has been expanded to postoperative analgesia in foot and ankle surgeries. The objective of this study was to evaluate the analgesia time and pain intensity, using objective scores, after peripheral nerve block in foot and ankle surgeries. METHODS: Patients who underwent surgery by the foot and ankle group of our institution from March 2016 to January 2017 were invited to participate in this prospective, randomized, and blinded study after signing an informed consent form...

BACKGROUND: Peripheral nerve block (infiltration of local anaesthetic around a nerve) is used for anaesthesia or analgesia. A limitation to its use for postoperative analgesia is that the analgesic effect lasts only a few hours, after which moderate to severe pain at the surgical site may result in the need for alternative analgesic therapy. Several adjuvants have been used to prolong the analgesic duration of peripheral nerve block, including perineural or intravenous dexamethasone. OBJECTIVES: To evaluate the comparative efficacy and safety of perineural dexamethasone versus placebo, intravenous dexamethasone versus placebo, and perineural dexamethasone versus intravenous dexamethasone when added to peripheral nerve block for postoperative pain control in people undergoing surgery...

Bupivacaine is a long-acting local anesthetic (LA) used for cutaneous infiltration, peripheral nerve blocks, epidural and spinal anesthesia. However, its application may result in cardiovascular complications such as: hypotension, bradycardia, cardiac arrest and toxic myocardial injury. The authors describe a 53-year-old male with a history of cigarette smoking, admitted for an elective inguinal hernia surgery. Before surgery, the patient received subarachnoid injection of bupivacaine (20 mg). After the operation, he developed transient hypotension...

Peripheral nerve blocks are popular as a mode of anaesthesia for limb surgery and their beneficial effects are well documented in elective surgery. However, concerns have been raised about potential rebound pain outweighing the benefits in acute ankle fracture surgery. Furthermore, pain scores and morphine consumption do not provide a full picture, as pain is subjective. To evaluate the clinical usefulness of peripheral nerve blocks, we explored patients' expectations and experiences by means of semi-structured interviews analysed with systematic text condensation...

Cryoneurolysis entails using low temperatures to reversibly ablate nerves, with a subsequent analgesia duration measured in weeks or months. Previously, clinical applications for acute pain were limited because treatment originally required exposing the target nerve surgically. However, three developments have now made it possible to provide prolonged postoperative analgesia by cryoneurolysis: 1) new portable, hand-held cryoneurolysis devices, 2) ultrasound machine proliferation, and, 3) anesthesiologists trained in ultrasound-guided peripheral nerve block administration...

Frederic Michard
Smartphones and electronic tablets (e-tablets) have become ubiquitous devices. Their ease of use, smartness, accessibility, mobility and connectivity create unique opportunities to improve quality of surgical care from prehabilitation to rehabilitation. Before surgery, digital applications (Apps), serious games and text messaging may help for a better control of risk factors (hypertension, overweight), for smoking cessation, and for optimizing adherence to preoperative recommendations (e.g., regarding anticoagulation or antihypertensive treatments)...
