This report delineates the efficacy of local anesthesia in the performance of arthroscopic surgery of the knee. A retrospective review of 500 cases revealed that only three required administration of general anesthesia to successfully complete the procedure. A prospective study comparing fentanyl, midazolam, and fentanyl/midazolam combinations as intravenous supplements was performed. Meticulous surgical technique combined with local anesthesia and some form of intravenous sedation in minimal therapeutic dosage will provide satisfactory conditions to perform surgical arthroscopy of the knee.

Preoperative halo-pelvic traction leading to near-complete airway obstruction in a child with severe thoracic lordosis and scoliosis: a case report.

Background: Halo-pelvic traction is a relatively safe treatment for preoperative spinal deformity correction in patients with severe scoliosis. Common device-related complications include local infection, back discomfort, and nerve compression symptoms. However, there are potential risks of mechanical compression of bronchial structures, especially in patients with severe thoracic lordosis and scoliosis, which can lead to life-threatening airway obstruction.

Early repair of flexor tendon injuries is ideal, but delays are common. We studied the outcomes of flexor tendon repairs delayed from 5 days to 6 months and carried out under wide-awake local anaesthesia with no tourniquet (WALANT). Twenty-four patients (29 fingers) who underwent primary flexor tendon repair on zone II using a four- to six-strand core suture technique, followed by controlled early active motion therapy.

Sotos syndrome is a genetic disorder characterized by distinct facial features, intellectual disability, and overgrowth. In this case, a patient with Sotos syndrome presented with severe intellectual disability, for which general anesthesia was initially considered. However, at the request of the patient's guardian, the treatment was performed under intravenous sedation.

Peribulbar anesthesia is mainly used for cataract surgery. Many studies had used atracurium and rocuronium as an additive to the local anesthetic (LA) drugs in eye surgery. The aim of this study is to evaluate the efficacy of adding atracurium versus rocuronium to a local anesthetic mixture, in providing an early onset of orbital akinesia and corneal anesthesia during cataract surgery.

Introduction: This study aimed to compare the effectiveness of mental nerve block (MINB) and conventional inferior alveolar nerve block (IANB) anesthesia during endodontic treatment of mandibular first and second premolars with symptomatic irreversible pulpitis (SIP).
Methods: In this randomized, double-blind, clinical trial, 120 patients undergoing endodontic treatment of mandibular premolars were randomly assigned to IANB (n=60) or MINB (n=60) using 4% articaine with 1:100,000 epinephrine hydrochloride. Pain levels were evaluated preoperatively and during cold tests, cavity preparation, and pulp extirpation using the Numerical Rating Scale (NRS).
