Filter by:Coughing during tracheal extubation can be associated to adverse effects like tachycardia, arterial hypertension (AHT), increase of intracranial pressure (ICP) and intraocular pressure (IOP), and the dehiscence of surgical wounds. In ophthalmic, head and neck, and abdominal surgery, and in several other neurosurgical interventions it is vital to prevent these effects. The incidence of laryngeal irritation due to orotracheal intubation hinders patient comfort in the immediate postoperative (POP) period and no pharmacological intervention has been yet proven to prevent it. At the end of the surgical procedure, the depth of the anesthetic plane decreases with the concomitant suspension of the anesthetic agents. However, the patient still requires ventilatory support through the endotracheal tube (EDT). The physical stimulation of the trachea created by this foreign body leads to the activation of the sympathetic nervous system, expressed in AHT, tachycardia, and ICP. To tolerate the EDT and prevent these effects, different maneuvers have been tested such as extubating the patient in a deep anesthetic plane or administering intravenous (IV) narcotics with the entailed complications: airway (AW) obstruction and hypercapnia, and the aspiration of an unprotected AW. Progress has been made with the introduction of ultrashort acting opioids, with significant statistical results. Moreover, beta-blockers, calcium channel blockers, angiotensin converting enzyme inhibitors and dexmedetomidine have been used to decrease the hemodynamic impact associated to tracheal extubation. The use of both IV and intratracheal lidocaine in doses ranging from 1 mg/kg to 3 mg/kg, has been studied with controversial results. In view of the above, and as lidocaine is the most commonly used low-cost drug in all operating rooms with a good safety profile when used at low doses, the purpose of this study is twofold: to assess its effects at reducing coughing and to evaluate its hemodynamic impact when administering IV 1 mg/kg prior to extubation. Then, the efficiency of reducing the incidence of sore throats after the immediate POP shall be investigated.
This study seeks to investigate lidocaine infusion to reduce occurrence of chronic postoperative pain at 3-month after inguinal herniotomy
This study seeks to investigate lidocaine infusion to reduce postthoractomy pain syndrome after thoracic Surgery
The aim of this project is to study the role of transient receptor potential (TRP-) channel V1 (TRPV1+) fibers in the development of cutaneous inflammation induced by epidermal Ultraviolet-B damage. Moreover, in this project the investigators want to evaluate if the capsaicin-desensitization action can still be induced in a skin area pretreated with topical, local anesthetic lidocaine.
In elective gynecology and general surgery patients age 18 and over requiring endotracheal tube (ETT) intubation, what is the efficacy of ropivacaine 0.5% vs. lidocaine 2% as the medium to inflate the ETT cuff, compared to the standard of air, in reducing the incidence and severity of POST on post-op day one?
This study is to determine if there is a clinically meaningful difference in pain perception for women during in-office diagnostic flexible cystoscopy when using lidocaine gel vs plain lubricant. This will be a double blinded randomized control trial.
The aim of our study is to compare the analgesic effect of topical application of lidocaine-prilocaine cream and lidocaine infiltration during insertion of birth control implants
The objective of this trial is to determine whether an opioid-free general anesthetic (OFA) technique utilizing ketamine, dexmedetomidine, lidocaine, and gabapentin can help reduce postoperative respiratory depression in the post-anesthesia care unit and ward in children with sleep-disordered breathing undergoing tonsillectomy when compared with traditional opioid-containing techniques. It is expected that this OFA regimen will have a measurable reduction on postoperative respiratory depression in children with sleep-disordered breathing.
The purpose of the study is to determined whether the administration of alkalized 4% lidocaine (160 mg) in the endotracheal tube cuff is effective in diminishing the incidence of coughing at extubation in surgeries lasting more than 2 hours without the use of nitrous oxide as an anesthetic agent.
The aim of the present study is to compare the antiarrhythmic and myocardial protective effect between lidocaine, dexmedetomidine, and their combined infusion in subjects undergoing coronary artery bypass graft.
