Takeshi Nomura, Itaru Watanabe
Point-of-care ultrasonography has become widely used in diagnosis and managements of patients. In the field of anesthesiology, ultrasound guided nerve blocks and central venous catheterization (CVC), and transesophageal echocardiography (TEE) have become popular. Now, ultrasound devices are familiar to anesthesiologists. In pre-anesthetic patient risk evaluation, the sonographic results of transthoracic echocardiography (TTE) or the examination of deep venous thrombus are often helpful for anesthesia planning...

Spectral analysis of ultrasound radiofrequency backscatter has the potential to identify intercostal blood vessels during ultrasound-guided placement of paravertebral nerve blocks and intercostal nerve blocks. Autoregressive models were used for spectral estimation, and bandwidth, autoregressive order and region-of-interest size were evaluated. Eight spectral parameters were calculated and used to create random forests. An autoregressive order of 10, bandwidth of 6 dB and region-of-interest size of 1.0 mm resulted in the minimum out-of-bag error...

BACKGROUND: Locoregional anaesthetic techniques can facilitate certain surgeries being performed under standing procedural sedation. The second and third spinal cervical nerves (C2, C3) are part of the cervical plexus and provide sensory innervation to the peri-laryngeal structures in people; block of these nerves might permit laryngeal lateralisation surgery in horses. OBJECTIVES: To describe the anatomical basis for an ultrasound-guided cervical plexus block in horses...

BACKGROUND: Anatomical knowledge dictates that regional anaesthesia after total hip arthroplasty requires blockade of the hip articular branches of the femoral and obturator nerves. A direct femoral nerve block increases the risk of fall and impedes mobilisation. We propose a selective nerve block of the hip articular branches of the femoral nerve by an ultrasound-guided injection in the plane between the iliopsoas muscle and the iliofemoral ligament (the iliopsoas plane). The aim of this study was to assess whether dye injected in the iliopsoas plane spreads to all hip articular branches of the femoral nerve...

BACKGROUND AND OBJECTIVES: This randomized trial aimed to assess if a combined suprascapular-axillary nerve block (SSB) is noninferior (margin = 1.3 on a 0- to 10-point scale) to interscalene block (ISB) in treating pain after arthroscopic shoulder surgery. Secondary end points included opioid consumption, dyspnea, discomfort associated with muscle weakness, and patient satisfaction. METHODS: One hundred patients undergoing arthroscopic shoulder surgery were randomized to receive ultrasound-guided ISB (n = 50) or SSB (n = 50)...

Ultrasound (US)-guided transversalis fascia plane block (TFPB) was first described by Hebbard as a technique for blockade of T12-L1 nerves. Although this technique appears similar to the quadratus lumborum 1 block, the point of injection is more caudal and anterior, specifically targeting ilioinguinal and iliohypogastric nerves. There are only few published data on US-guided TFPB demonstrating effective postoperative analgesia in iliac crest bone graft harvesting. We report the use of US-guided TFPB in a patient undergoing inguinal herniorrhaphy...

Background and Aims: Opioids are associated with postoperative nausea, vomiting, drowsiness, and increased analgesic requirement. A nonopioid anesthesia technique may reduce morbidity, enable day care surgery, and possibly decrease tumor recurrence. We compared opioid-free, nerve block-based anesthesia with opioid-based general anesthesia for breast cancer surgery in a prospective cohort study. Material and Methods: Twenty four adult American Society of Anesthesiologists grade I-III patients posted for modified radical mastectomy (MRM) with axillary dissection were induced with propofol and maintained on isoflurane (0...

BACKGROUND AND OBJECTIVES: This randomized trial compared ultrasound (US)-guided interscalene block (ISB) and small-volume supraclavicular block (SCB) for arthroscopic shoulder surgery. We hypothesized that SCB would provide equivalent analgesia to ISB 30 minutes after surgery without the risk of hemidiaphragmatic paralysis (HDP). METHODS: All patients received an US-guided intermediate cervical plexus block. In the ISB group, US-guided ISB was performed with 20 mL of levobupivacaine 0...

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...

Hemidiaphragmatic paralysis is initially recognised as postoperative respiratory distress. The subsequent sequential management of the patient following arthroscopic shoulder surgery under interscalene block is described. Ultrasound-guided technique is considered to be the safest for interscalene block. Reducing the volume of anaesthetic used reduces its spread to the phrenic nerve and thus reduces the incidence of hemidiaphragmatic paralysis. Furthermore, a reduction in anaesthetic volume has equivalent analgesic efficacy...

PURPOSE: Analgesic efficacy of ultrasound-guided transverse abdominis plane block, administered a little more medially, just close to theorigin of the transverse abdominis muscle has not yet been investigated in patients undergoing unilateral inguinal hernia repair. We hypothesised that medial transverse abdominis plane block would provide comparable postoperative analgesia to ilioinguinal-iliohypogastric nerve block in inguinal hernia repair patients. METHODS: This prospective, randomised trial was conducted in 50 ASA I and II male patients ≥ 18 years of age...

Postoperative analgesia is imperative in the youngest patients. Pain, especially if experienced during childhood, has numerous adverse effects-from psychological, through complications of the underlying disease (prolonged treatment, hospital stay, and increased costs of the treatment) to an increase in the incidence of death due to the onset of the systemic inflammatory response. Peripheral blocks provide analgesia for 12-16 h, and are safer due to rare side effects that are easier to treat. The continuous peripheral block (CPNB) has been increasingly used in recent years for complete and prolonged analgesia of pediatric patients, as well as a part of multidisciplinary treatment of complex regional pain syndrome...

Here we present two cases of gastrostomy insertion via laparotomy in patients with malignant esophageal disease. Patients were ASA (American Society of Anesthesiologists) physical status III and IV. The patients presented as very high risk for general anesthesia, so we decided to use unilateral left sided paravertebral block (PVB) on four thoracic levels along with contralateral local infiltration at the gastrostomy insertion site. We present two cases, one of them a 57-year-old male ASA III patient scheduled for a gastrostomy procedure due to esophageal cancer with infiltration of the trachea...
