Objectives: Assess the efficacy of an anesthetic cream for cardiac catheterization.
Patients And Methods: Percutaneous anesthesia was studied in a series of 100 consecutive patients undergoing cardiac catheterization. The anesthesia was composed with an eutetic mixture of local anesthetics and applied precisely over the puncture area in a randomized controlled study. After admission, patients were randomized into two groups: 50 patients received lidocaine infiltration and 50 patients received associated cream and infiltration. Percutaneous anesthesia was to be applied 2 hours before entering the operating room.
Results: No complication developed with this cream combined with lidocaine infiltration. Serum concentration indicated very low levels which were very well tolerated. Patient comfort improved with the anesthetic cream-lidocaine infiltration association.
Conclusion: The use of an anesthetic cream is safe and effective, especially combined with lidocaine infiltration during cardiac catheterization. Cost is high and the association might be reserved for special indications (obesity, children).

Activity-Regulated Cytoskeleton-Associated Protein Gene Expression Is Associated With High Infiltration of Stromal Cells and Immune Cells, but With Less Cancer Cell Proliferation and Better Overall Survival in Estrogen Receptor-Positive/Human Epidermal Growth Factor Receptor 2-Negative Breast Cancers.

Background: Peritumoral lidocaine infiltration prior to excision is associated with better survival in breast cancer (BC), which led us to hypothesize that innervation to the tumor affects its biology and patient survival. Activity-regulated cytoskeleton-associated protein (ARC) gene expression is known to be regulated by neuronal activity. Therefore, we studied the clinical relevance of ARC gene expression as a surrogate of neuronal activity in BC.

Objective: To assess the efficacy and safety of subcutaneous perispinal infiltration of low dose of triamcinolone and lidocaine indicated for pain control in patients with cervical osteoarthritis (COA).
Methods: Patients with symptomatic COA resistant to conventional treatment including anti-inflammatory drugs, analgesics, and physical therapy were included. Technetium-99 m pyrophosphate (99mTc-PYP) scintigraphy and computerized tomography (CT) fusion scans images were used for diagnosis of COA and as a guide for level(s) of infiltration(s).
Background: The primary objective of this study was to compare the efficacy of lignocaine-dexamethasone and lignocaine-triamcinolone infiltration, along the spinal-epidural needle insertion pathway, to prevent backache after lower abdominal surgeries.
Methods: This prospective, double-blind randomized controlled study included a total of 150 patients, scheduled for elective lower abdominal surgery under combined spinal-epidural (CSE) anaesthesia. The patients were randomised into three groups Group L (Lignocaine, n=50), Group DL (Dexamethasone, Lignocaine, n=50), and Group TL (Triamcinolone, Lignocaine, n=50).
Evaluating Anesthesia Guidance for Rescue Analgesia in Awake Patients Undergoing Carotid Endarterectomy with Cervical Plexus Blocks: Preliminary Findings from a Randomized Controlled Trial.

Eversion carotid endarterectomy (CEA) in awake patients is performed using cervical plexus blocks (CPBs) with or without carotid artery sheath infiltration (CASI) under ultrasound guidance. Although adequacy of anesthesia (AoA) guidance monitors nociception/antinociception balance, its impact on intraoperative analgesia quality and perioperative outcomes in awake CEA remains unexplored. Existing literature lacks evidence on whether AoA-guided anesthesia enhances clinical outcomes over standard techniques.

Aims And Background: Local anesthetics play a crucial role in pain management in pediatric dentistry, where anxiety and fear are common among young patients. This study aimed to compare the anesthetic efficacy of 2% lignocaine with a 20-gauge needle in an inferior alveolar nerve block (IANB) and 4% articaine with a 24-gauge needle in a buccal nerve block (BNB) during the extraction of dentoalveolar abscesses in children aged 5-11 years.
Materials And Methods: A 12-month randomized controlled trial involving 100 healthy children was conducted following ethical standards.
