BACKGROUND: Dexmedetomidine has been proposed as a perineural local anaesthetic (LA) adjunct to prolong peripheral nerve block duration; however, results from our previous meta-analysis in the setting of brachial plexus block (BPB) did not support its use. Many additional randomized trials have since been published. We thus conducted an updated meta-analysis. METHODS: Randomized trials investigating the addition of dexmedetomidine to LA compared with LA alone (Control) in BPB for upper extremity surgery were sought...

BACKGROUND AND AIMS: The cost effectiveness of ultrasound-guided regional anesthesia is an issue which requires discussion. Based on our experience, we hypothesized that this is an economically viable option. MATERIAL AND METHODS: In this retrospective study, we included 90 patients who underwent upper extremity surgeries in our institute solely under ultrasound (USG)-guided brachial plexus blocks in a year. The cost of the block was derived by adding the cost of the material and drugs used for the block...

A meta-analysis was performed to evaluate the efficacy of local anesthesia in alleviating pain during prostate biopsy. We searched relevant articles in PubMed and Embase. The included studies should be randomized controlled trials (RCT) using local anesthesia to alleviate pain during biopsy, which was recorded by a pain scale. Analgesic efficacy of different local anesthesia techniques were analyzed, including intrarectal local anesthesia (IRLA), periprostatic nerve block (PNB), pelvic plexus block (PPB) and intraprostatic local anesthesia (IPLA)...

Adrenaline is known to prolong the duration of local anesthesia but its effects on the pharmacokinetic processes of local anesthetic drugs are not fully understood. Our objective was to develop a compartmental model for quantification of adrenaline's impact on the pharmacokinetics of perineurally-injected lidocaine in the dog. Dogs were subjected to paravertebral brachial plexus block using lidocaine alone or adrenalinated lidocaine. Data was collected through a prospective, randomised, blinded crossover protocol performed over three periods...

Neurogenic bowel dysfunction occurs in a large percentage of adult patients with spina bifida (SB) and spinal cord injury (SCI), significantly affecting their quality of life. Although bowel motility is autonomously regulated by the enteric nervous system (ENS), disruption of the modulation of the ENS by extrinsic innervation as present in many patients with SB and SCI might lead to motility disorders. In order to gain insight in the pathophysiology, we studied histological changes of the neuromuscular structures in the colon of SB and SCI patients...

BACKGROUND: Although intravenous dexamethasone prolongs the analgesic duration of interscalene brachial plexus block, it is uncertain whether this effect can be observed using lower doses of dexamethasone. This study evaluated the impact of intravenous dexamethasone (4 mg and 10 mg) on the analgesic duration of single-shot interscalene block after arthroscopic shoulder surgery. We hypothesized that both doses would prolong the analgesic duration compared with placebo. METHODS: This was a prospective double-blind randomized placebo-controlled study in patients undergoing elective arthroscopic shoulder surgery under regional anesthesia with a single-shot interscalene block (0...

Quadratus lumborum (QL) block was first described several years ago, but few articles have been published regarding this technique, for the most part case series involving abdominal surgery. We report 2 cases of prolonged, extensive block of thoracic and lumbar dermatomes after QL block in patients undergoing different hip surgery procedures for whom QL block was used in place of lumbar plexus block. Further prospective studies comparing these 2 techniques are necessary to better characterize the role of QL block in hip surgery...

CONTEXT: Celiac plexus block (CPB) (is an effective way to reduce cancer-associated pain in upper abdominal malignancies. AIMS: To evaluate the efficacy and safety of different volumes of 70% alcohol in CPB. SETTINGS AND DESIGN: Prospective, randomized, controlled clinical study. SUBJECTS AND METHODS: Thirty patients of carcinoma gall bladder were randomly divided into three groups (n = 10) to receive 20, 30, and 40 ml of 70% alcohol in CPB...

Background: Carotid endarterectomy (CEA) is the standard treatment modality for the prevention of stroke in patients with carotid stenosis. This study reports our experiences during CEA with routine awake tests under regional anesthesia (RA) combined with light sedation by dexmedetomidine infusion. Materials and Methods: We retrospectively reviewed 23 patients who had undergone CEA between April 2013 and June 2015. All patients underwent the awake test during CEA with cervical plexus block and light sedation by continuous dexmedetomidine infusion...

INTRODUCTION: Regional anaesthesia is commonly preferred for arteriovenous fistula (AVF) creation. Previous studies suggest a shorter block duration in patients with chronic renal failure, maybe because of the changes in regional blood flow. The aim of our study was to evaluate the duration of the axillary block with 1.5% mepivacaine in patients with chronic renal failure scheduled for AVF compared with healthy controls. METHODS: Patients scheduled for AVF creation for the first time (GIRC) were included...

There is evidence that R-type Ca(2+) channels contribute to synaptic transmission in the myenteric plexus. It is unknown if R-type Ca(2+) channels contribute to neuromuscular transmission. We measured the effects of the nitric oxide synthase (NOS) inhibitor, nitro L-arginine (NLA), Ca(2+) channel blockers and apamin (SK channel blocker) on neurogenic relaxations and contractions of the guinea pig ileum longitudinal muscle-myenteric plexus (LMMP) in vitro. We used intracellular recordings to measure inhibitory junction potentials (IJPs)...

BACKGROUND AND AIMS: Hypotensive anaesthesia reduces intra-articular bleed and promotes visualisation during arthroscopy. The haemodynamic effects of inhalational agents isoflurane and sevoflurane were studied extensively, and both were found to reduce mean arterial pressures (MBP) to an equivalent magnitude. We investigated the relative ability of isoflurane vis-a-vis sevoflurane to maintain the target systolic blood pressure (SBP) in patients undergoing shoulder arthroscopic procedures...

BACKGROUND: Parotidectomy is usually performed while the patient is under general anesthesia, however, sedation with locoregional anesthesia could be an alternative. METHODS: Fifteen adult patients with parotid tumors of the superficial lobe were included in this study. Anesthetic procedure consisted of sedation associated with cervical plexus and auriculotemporal nerve block. Sedation was managed based on the bispectral index. RESULTS: Superficial parotidectomies were performed in 13 patients, and combined partial resections were performed in 2 patients...

Background. Distal arm surgery is widely performed under regional anesthesia with brachial plexus block. The preponderance of evidence for the efficacy relies upon injection of local anesthetic in excess of 30 mL. We aimed to compare three different ultrasound-guided brachial plexus block techniques restricting the total volume to 20 mL. Methods. 120 patients were prospectively randomized to ultrasound-guided brachial plexus block with 20 mL ropivacaine 0.75% at either the supraclavicular, infraclavicular, or axillary level...

Shoulder surgery can result in significant postoperative pain. Interscalene brachial plexus blocks (ISBs) constitute the current criterion standard for analgesia but may be contraindicated in patients with pulmonary pathology due to the inherent risk of phrenic nerve block and symptomatic hemidiaphragmatic paralysis. Although ultrasound-guided ISB with small volumes (5 mL), dilute local anesthetic (LA) concentrations, and LA injection 4 mm lateral to the brachial plexus have been shown to reduce the risk of phrenic nerve block, no single intervention can decrease its incidence below 20%...
