Local anaesthesia adjuvant

BACKGROUND: Sinonasal Mucosal Melanoma (SNMM) is a rare but aggressive disease. Surgery with free margins, when feasible, is the treatment of choice. In the last three decades, electrochemotherapy (ECT) has emerged as a local ablative procedure, performed with the Cliniporator, for cutaneous and mucosal tumours of different histology. We present a case report of an ECT treatment performed by means of a new endoscopic electrode, on an elderly patient affected by primary SNMM. METHODS: An 88-year-old man with a diagnosis of SNMM (cT4aN0M0)-Stage IV, of the left nasal fossa presented at our institution...

Sickle cell disease is characterised by episodes of vaso-occlusive crisis, a painful complication. Regional anaesthesia has shown promising results in reducing opioid consumption and pain scores. Patients with vaso-occlusive crises who underwent regional anaesthesia in the paediatric intensive care unit were studied. Data regarding pain location, regional analgesia technique, the local anaesthetic used and dose, daily opioid consumption, daily pain scores, use of adjuvants and complications were recorded. The primary outcome was to evaluate the effect of regional anaesthesia on opioid consumption...

BACKGROUND: Failed spinal anaesthesia causes prolonging of operation time, insufficient analgesia for surgery and needs repeating spinal anaesthesia which in turn causes local anaesthesia toxicity, high spinal and total spinal, and conversion to general anaesthesia. However, the problem remains unexplored in Amhara regional state comprehensive specialized hospitals. OBJECTIVE: To determine incidence and factors associated with failed spinal anaesthesia among patients undergoing surgery in selected Amhara National Regional State comprehensive specialized hospitals, Northwest Ethiopia, 2023...

BACKGROUND: The mechanisms for spinal cord stimulation (SCS) to alleviate chronic pain are only partially known. We aimed to elucidate the roles of adenosine A1 and A3 receptors (A1R, A3R) in the inhibition of spinal nociceptive transmission by SCS, and further explored whether 2'-deoxycoformycin (dCF), an inhibitor of adenosine deaminase, can potentiate SCS-induced analgesia. METHODS: We used RNAscope and immunoblotting to examine the distributions of adora1 and adora3 expression, and levels of A1R and A3R proteins in the spinal cord of rats after tibial-spared nerve injury (SNI-t)...

BACKGROUND: Superiority of perineural over intravenous dexamethasone at extending nerve block analgesia has been suggested but without considering the dose-response relationships for each route of administration. METHODS: Randomised control studies that evaluated intravenous or perineural dexamethasone as an adjuvant to unilateral peripheral nerve blocks in adults were searched up to October 2023 in MEDLINE, Central, Google Scholar, and reference lists of previous systematic reviews...

BACKGROUND: Despite being a commonly performed surgical procedure, pain management for appendicectomy is often neglected because of insufficient evidence on the most effective treatment options. OBJECTIVE: To provide evidence-based recommendations by assessing the available literature for optimal pain management after appendicectomy. DESIGN AND DATA SOURCES: This systematic review-based guideline was conducted according to the PROSPECT methodology...

Throughout the course of oncological disease, the majority of patients require surgical, anaesthetic and analgesic intervention. However, during the perioperative period, anaesthetic agents and techniques, surgical tissue trauma, adjuvant drugs for local pain and inflammation and other non-pharmacological factors, such as blood transfusions, hydration, temperature and nutrition, may influence the prognosis of the disease. These factors significantly impact the oncologic patient's immune response, which is the primary barrier to tumour progress, promoting a window of vulnerability for its dissemination and recurrence...

Regional anaesthesia (RA) has an important and ever-expanding role in ambulatory surgery. Specific practices vary depending on the preferences and resources of the anaesthesia team and hospital setting. It is used for various purposes, including as primary anaesthetic technique for surgery but also as postoperative analgesic modality. The limited duration of action of currently available local anaesthetics limits their application in postoperative pain control and enhanced recovery. The search for the holy grail of regional anaesthetics continues...

The superficial cervical plexus nerve block [SCPNB] procedure is frequently used throughout head and neck surgery because it is simple to learn and has a low rate of complications. The investigation of this method might produce superior outcomes in treating frequent maxillofacial disorders including mandibular fractures and infections of the odontogenic region. The SCPNB is known to play a part in the medical evacuation of head and neck abscesses, the excision of superficial diseases in the perimandibular region, and the therapy of mandibular fracture, despite the dearth of research in this area...

INTRODUCTION: Spinal anaesthesia consists of administering a local anaesthetic in the subarachnoid space, thus causing sensory, motor, and autonomic nerve conduction block. Currently, recovery from spinal anaesthesia is evaluated by the return of motor function, without considering the autonomic blockade, which is responsible for most complications of the technique. Heart rate variability (HRV) is an indirect method to measure the autonomic nervous system and may be useful in assessing autonomic recovery after spinal anaesthesia...

INTRODUCTION AND IMPORTANCE: Acinic cell carcinoma (AciCC) is a rare entity in which high-grade transformation (HGT), formerly dedifferentiation, is uncommon. This case report presents a rare case of AciCC, with rapid transformation to metastatic high-grade dedifferentiated pathology after initial curative treatment. CASE PRESENTATION: A 58-year-old woman presented in the medical oncology clinic with a progressive swelling on the right side of her face. Magnetic resonance imaging revealed a 5 × 5 cm lobulated parotid gland lesion, and fine needle aspiration biopsy was consistent with carcinoma...

BACKGROUND: Nalbuphine and clonidine are used as adjuvants to intrathecal local anesthetics, but studies on their comparative efficacy have shown inconsistent results. This study aimed to compare nalbuphine, clonidine, or normal saline as adjuvants to intrathecal hyperbaric bupivacaine in orthopedic lower limb surgeries.  Method: Sixty-three American Society of Anesthesiologists (ASA) I/II patients between 18 and 60 years old with lower limb fractures were randomized into three groups (n=21 each)...

BACKGROUND: Lentigo maligna melanoma is mainly localised in the head and neck region in elderly patients. Due to its slow horizontal growth, it has a good prognosis compared to other melanoma subtypes, but specific data are rare. OBJECTIVES: The aim of this study was to investigate sentinel lymph node biopsy in lentigo maligna melanoma under local anaesthesia and to discuss the benefit. METHODS: Investigation of patients with lentigo maligna melanoma and tumour thickness ≥1 mm treated at the Department of Dermatology, University Medical Centre Tuebingen, between January 2008 and October 2019...

BACKGROUND: Spinal anaesthesia is the most commonly used technique for lower limb orthopaedic surgeries as it is economical and easy to administer. Opioids as adjuvants to local anaesthetics during spinal anaesthesia have played a vital role in reducing post-operative pain qualitatively and effectively. METHODS: This prospective randomised study was conducted on 100 patients divided into two groups scheduled for lower limb orthopaedic surgeries. Group bupivacaine fentanyl (BF) received 25 mcg of fentanyl with 15 mg of bupivacaine and Group bupivacaine nalbuphine (BN) received 1 mg of nalbuphine and 15 mg of 0...

BACKGROUND: Pain after craniotomy can be intense and its management is often suboptimal.

DESIGN: A systematic review using procedure-specific postoperative pain management (PROSPECT) methodology was undertaken. DATA SOURCES: Randomised controlled trials and systematic reviews published in English from 1 January 2010 to 30 June 2021 assessing pain after craniotomy using analgesic, anaesthetic or surgical interventions were identified from MEDLINE, Embase and Cochrane Databases...

BACKGROUND: Peripheral regional anaesthesia is frequently used for upper extremity surgery. To prolong the duration of analgesia, adjuvants can be added to single-injection local anaesthetics. Despite attempts to compare several adjuvants in pairwise meta-analyses, a comprehensive comparison is still missing. OBJECTIVE: The objective of this network meta-analysis was to determine the effectiveness of adjuvants in upper extremity peripheral nerve blocks. DESIGN: A systematic review of randomised controlled trials with network meta-analyses...

Spinal anaesthesia is an established and frequently used anaesthetic technique in adults. However, this versatile regional anaesthetic technique is less frequently used in paediatric anaesthesia even though it can be used for minor (e.g. inguinal hernia repair) and major (e.g. cardiac surgery) surgical procedures. The aim of this narrative review was to summarize the current literature with regard to technical aspects, surgical context, choice of drugs, potential complications, as well as the effects of the neuroendocrine surgical stress response and potential long-term effects of anaesthesia during infancy...

METHODS: This single centered randomized, double blind trial was held in 2021 after approval of ethical committee at the Eye Hospital, Riyadh, Saudi Arabia. Cataract patients to be operated using local anesthesia were randomly assigned to two groups; Group magnesium sulfate (MS) received 50 mg/0.5 ml of magnesium sulfate and Group normal saline (NS) received 0...

The combination of drugs and routes of administration produces a synergistic effect, and one of the most important components of multimodal analgesic strategies are, therefore, nerve blocks for pain management. The effect of a local anaesthetic can be prolonged by administering an adjuvant. In this systematic review, we included studies on adjuvants associated with local anaesthetics in peripheral nerve blocks published in the last 5 years in order to evaluate their effectiveness. The results were reported according to the PRISMA guidelines...
