Introduction: Topical anesthetics are frequently used to decrease the pain associated with a variety of procedures including cutaneous surgery, cosmetic treatments and laser surgery. They are also routinely used in children prior to invasive procedures, such as venipuncture. The ideal topical anesthetic should safely increase patient comfort associated with these procedures with minimal potential for adverse effects.
Areas Covered: Topical anesthetic formulations have evolved over the past several decades to include formulations with improved efficacy and side effect profiles. However, significant adverse events are still possible.
Expert Opinion: Medical practitioners can mitigate the risk of side effects and toxicity with careful selection of anesthetic type, concentration, body location and dermatologic procedure. Compounded formulations should be used with caution in medical settings only on limited body surface areas without occlusion. This review presents a detailed analysis of products available, reported complications and an outline for appropriate use of topical anesthetics in combination with dermatologic procedures.

Pharmacological Postoperative Pain Management for Paediatric Dental Extractions Under General Anaesthesia: A Systematic Review.
Pain Res Manag

Australian Research Centre for Population Oral Health, Adelaide Dental School, Faculty of Health and Medical Sciences, University of Adelaide, Adelaide, South Australia, Australia.
General anaesthesia (GA) as a pharmacological behaviour management strategy may be indicated for dental extractions in children unable to cooperate in the dental chair. Pain is the most common postoperative complication in children following dental GA. There is conflicting evidence available on the efficacy of local anaesthetic (LA) agents for postoperative pain management following dental extraction.

Postoperative pain in children leads to an immense stress response than adults, leading to an increased hospital stay and "pain memory." Caudal epidural anesthesia is one of the most reliable, popular, and safe techniques that provide proper analgesia for infra-umbilical surgeries. A combination of local anesthetics and opioids reduces the dose-related adverse effects of each drug independently.

Background: We systematically reviewed the evidence on the effect of anesthetic methods and drugs on the incidence of postoperative cognitive dysfunction (POCD) after cataract surgery.
Methods: The Web of Science, PubMed, and Scopus databases were searched for relevant English reports published from 2000 to August 2024. After full-text screening and checking the quality assessment of each article using the JBI checklist, 9 relevant articles were included in this study.
"Mechanical Integrity Assessment of Polymethylmethacrylate Bone Cement Incorporating Local Anesthetics: Implications for Joint Arthroplasty".

Hospital Clínic Barcelona, Department of Orthopaedic Surgery and Traumatology. Villarroel, 170. 08036 Barcelona, Spain.
Background: Effective management of postsurgical pain following arthroplasty remains a challenge, lacking a definitive gold standard. As most knee and hip arthroplasties are cemented or hybrid, we used the property of bone cement as a drug carrier and added powdered local anesthetics (lidocaine hydrochloride and bupivacaine hydrochloride) to the polymethylmethacrylate (PMMA) as analgesics. However, the addition of drugs to bone cement may compromise its mechanical properties, necessitating a thorough analysis.

Background: Total knee arthroplasty (TKA) is associated with moderate to severe postoperative pain. Pain control is crucial for rapid mobilisation and reduces side effects as well as the length of hospital stay. In this context, a variety of multimodal pain control regimes show good pain relief, including several nerve blocks, iPACK and local infiltration analgesia (LIA).
