Filter by:Transnasal Fiberoptic Laryngoscopy (TFL) is a common procedure in the otolaryngology clinic for the examination of vocal cord appearance and function, inspection and follow up of benign and malignant lesions, and investigating foreign body ingestion. There are many forms for applying preprocedural local nasal anesthesia such as atomizers, nebulizers, spray, soaked pads, or local anesthetic gel application. This study compares the effect of buffered versus plain lidocaine for local nasal anesthesia.
Introduction The posterior Quadratus Lumborum Block (pQLB) has been used in postoperative pain management after Cesarean Section (CS). However, there are no data about pQLB safety in pregnants, at increased risk of local anesthetic systemic toxicity (LAST). The purpose of the present study was to explore the efficacy and the safety of adding epinephrine to ropivacaine for bilateral pQLB vs. bilateral pQLB performed with ropivacaine alone in CS. Methods Fifty-two pregnants were consecutively allocated to one of 2 groups [e-pQLB (0.375% ropivacaine+100 mcg epinephrine) or pQLB (0.375% ropivacaine)] and the investigators evaluated if the adjunct of epinephrine to ropivacaine increases of efficacy (measured as opioid consumption during the first 24 postoperative hours, time for first request of opioid and pain values reported by patients) and the safety (measured as peak and plasmatic concentration of ropivacaine) of pQLB.
Rib fractures are one of the most common injuries in trauma patients. These fractures are associated with significant pain as well as decreased ability to inspire deeply or cough to clear secretions, which together lead to complications of the lungs and breathing which leads to risks of further injury and even death. One recent study found that the ability to move air into and out of the lungs practically doubled with the administration of a single-injection Erector Spainae Plane Block (ESPB) while pain levels nearly halved. However, a single-injection nerve block lasts less than 24 hours while a perineural local anesthetic infusion (also termed a "continuous peripheral nerve block") may be administered for multiple days. This entails inserting a tiny tube through the skin and into the area around the nerves, after which more local anesthetic may be administered prolonging the numbing effects. The possibility of extending the duration of a ESPB with local anesthetic administration via a perineural catheter has not be investigated. We therefore are conducting a randomized, triple-masked, placebo-controlled, parallel-arm study to investigate the addition of a continuous ESPB to a single-injection ESPB following traumatic rib fractures. The primary outcome of this study will be the maximum inspired volume measured by incentive spirometry on the afternoon following the nerve block procedure. We hypothesize that the maximum inspired volume will be significantly increased in the afternoon following the procedure with the addition of a continuous ESPB to a single-injection ESPB.
The purpose of this randomized double-blind study is to compare the analgesic efficacy of the bilateral Erector Spinae Plane (ESP) block versus the bilateral Thoracic Paravertebral block (TPVB), by ultrasound-guided single injection in patients who underwent sternotomy for cardiac surgery.
Regional anesthesia and analgesia may maintain immune function, reduce surgical stress, and also reduce volatile anesthetics and opioids requirements. Local anesthetic drugs used in regional anesthesia and analgesia work to have anti-proliferative and cytotoxic effects on cancer cells. Pro-inflammatory cytokines such as IL-1, IL-6, and TNF-alpha increase in levels in peripheral nerves, spinal cord, brain (brain stem, locus sereleus, thalamus, hippocampus, and prefrontal cortex) after peripheral nerves are injured. The anti-inflammatory cytokine IL-10 is decreased in levels after peripheral nerve injury. The balance between pro-inflammatory and anti-inflammatory cytokines affects the severity of pain.
Tracheal intubation and general anesthesia has been considered a safe and conventional routine methodology for thoracic surgery, include multiple rib fratcure. However,adverse effects such as sore throat, pain, hoarseness, and respiratory complications are common after that. In this study, we decide to perform surgical stabiliazation of rib fractures by paravertebral block surgical stabiliazation of rib fractures under awake or appropriate sedation without endotracheal intubation keeping spontaneous respiration to investigate its safety and feasibility.
The purpose of this study is to determine the efficacy of lidocaine 2.5%/prilocaine 2.5% cream versus lidocaine 23%/tetracaine 7% ointment for topical anesthesia prior to a nonablative laser procedure.
This is a Phase 3, randomized, placebo-controlled, double masked, parallel design study in healthy subjects performed in the US. It is designed to evaluate the safety and anesthetic efficacy of AG-920 Sterile Topical Ophthalmic Solution.
The main aim of the investigator's study is to propose combination of local anesthetics and adjuvants that provides both adequate anesthesia during surgery and prolonged post-operative analgesia.
Many patients experience pain and anxiety from traditional needle anesthesia and may avoid necessary dental treatments. The needle-free liquid jet injection(NFLJI) could solve these problems. NFLJI delivers drug solutions by creating a micro-thin pressure liquid jet to penetrate the skin and disperse in the soft tissue. It has many advantages like eliminating injection pain, needle phobia and needle disposal. However, anesthesia techniques in dentistry were all developed for needle injection, and they are not very effective for NFLJI. Moreover, clinical trials of dental anesthesia using NFLJI have shown inconsistent efficacy. In this study, we aim to compare the clinical efficacy between NFLJI and needle dental anesthesia in pilot split-mouth cross-over randomized clinical trials, assess the feasibility to conduct such trial on a larger scale. Participants will be assigned to one of the following four groups: 1. Infiltration on a maxillary lateral incisor,2. Inferior alveolar nerve block, 3.Mental nerve block, 4. Infraorbital nerve block. Each participant will receive one injection with a needle and another one with NFLJI randomly at the same appointment. A washout period of 1 hour between two procedures for participants' to forget the previous experience. Needle injection will be performed according to clinical standards. NFLJI will be performed according to a guideline developed in our research group. Participants will stay in the clinic until the anesthesia effect disappear and be followed for one week. The primary outcome is the efficacy and effect of two anesthesia interventions. The secondary outcome is the pain and anxiety visual analogue scale before and during injection, taste preference, and complications. Additionally, patients' overall feelings for two interventions as well as any barriers to conducting such a trial will be recorded.
