A Comparison of Intrathecal Dexmedetomidine and Fentanyl as Adjuvants to 0.5% Hyperbaric Levobupivacaine for Lower Abdominal Surgeries: A Prospective, Double-Blinded, Randomized Controlled Trial.

Background Due to its affordability and ease of application, the subarachnoid block is the most frequently used method for lower abdominal procedures. Levobupivacaine has an onset of sensory and motor blockade comparable to that of bupivacaine and prolongs the duration of analgesia while facilitating quick recovery from motor block. Fentanyl and dexmedetomidine, when used as additives to intrathecal local anesthetic, can extend the duration of sensory and motor blockade and enhance postoperative analgesia.

Curr Pain Headache Rep
January 2025
Department of Anesthesiology, Perioperative, and Pain Medicine, Harvard Medical School, Brigham and Women's Hospital, Boston, MA, USA.
Purpose Of Review: The rhomboid intercostal and subserratus plane (RISS) block is an effective, safer alternative for managing postoperative acute pain following abdominal surgeries. The RISS block offers several advantages over traditional approaches, including reduced incidence of puncture-related complications, lower rates of systemic opioid consumption, and more consistent analgesic coverage of lower thoracic dermatomes.
Recent Findings: Despite a favorable safety profile, the RISS block carries potential risks, such as pneumothorax and local anesthetic systemic toxicity, particularly when long-acting anesthetics such as bupivacaine or ropivacaine are used.
Novel Ultrasound-Guided Sub-Piriformis Injection (SPI) May Produce Effective Analgesia for Both Open and Arthroscopic Hamstring Repair: A Case Report.
Cureus
November 2024
Education, Twin Oaks Anesthesia Services, Wesley Chapel, USA.
Open or arthroscopic repair of hamstring tear requires both hard and soft, posterior and proximal thigh analgesia. Regional injections to completely relieve this unique pain are not available to the best of our knowledge. We present a novel, single injection, performed under ultrasound guidance, that utilizes the deep piriformis space.

Cureus
November 2024
Department of Anaesthesiology, Uttar Pradesh University of Medical Sciences, Etawah, IND.
Background: The subarachnoid block is the predominant and relatively safe approach during lower limb orthopaedic operations. When used as an additive to intrathecal local anaesthetic, both fentanyl and dexmedetomidine can extend the duration of sensory and motor blockade and improve postoperative analgesia.
Objectives: The objective of this study is to assess and compare the efficacy of sequential administration of fentanyl and dexmedetomidine alongside 0.
Pre-Clinical Assessment of Bupivacaine-Loaded Poly(ester urea) Thin Films for Controlled Drug Release and Effective Pain Management After Surgery.
Adv Healthc Mater

Department of Chemistry, Duke University, Durham, NC, 27708, USA.
Safe, effective pain management remains one of the biggest challenges following surgical procedures. Despite widespread recognition of this problem and advances in the mechanistic understanding of pain signaling, post-surgical pain is often undermanaged, with opioid use remaining the clinical standard. As an alternative to current oral, systemic treatments, a degradable bupivacaine-loaded poly(ester urea) (PEU) thin film has been developed to deliver bupivacaine directly to the site of injury over an extended duration.
