This study aimed to investigate the clinical viability of utilizing the flexor hallucis brevis as an alternative site for neuromuscular monitoring compared to the conventional adductor pollicis. Patients were recruited from three medical centers. Cis-atracurium was administered, and two monitors were employed independently to assess neuromuscular blockade of the adductor pollicis and the ipsilateral flexor hallucis brevis, following a train of four (TOF) pattern until TOF ratios exceeded 0.9 or until the conclusion of surgery...

Benzylisoquinolinium neuromuscular blocking agents can precipitate bronchospasm either through allergy/anaphylaxis or isolated stimulation of mast cell histamine release. This report presents a 75-year-old female who attended the day surgery unit for a rigid cystoscopy under general anaesthesia. She had a hyper-reactive airway history of mild historic asthma and sensitivity to aerosols. After administration of atracurium at induction of anaesthesia, ventilation became challenging with no chest rise and a flat CO2 trace...

INTRODUCTION: Strabismus surgery under general anesthesia is a common procedure with rare complications in the form of hemorrhage, infection, slipped muscle, lost muscle, scleral perforation, and anterior segment ischemia. We report a unique case of bilateral optic neuritis following squint surgery under general anesthesia in a 15-year-old girl. METHODS: A 15-year-old girl presented with accommodative esotropia with V pattern. She underwent uneventful bilateral inferior oblique recession surgery under general anesthesia with Propofol 60 mg, Atracurium 30 mg, and Fentanyl 70 mcg...

OBJECTIVE: The aim of this study was to describe the onset and duration of action of escalating doses of atracurium in healthy, anesthetized goats. STUDY DESIGN: Randomized, blinded, triple crossover study. Animals A total of eight (five males and three females) healthy goats weighing 42.7-123.5 kg and aged from 11 months to 8 years. METHODS: Goats were anesthetized three times with propofol and anesthesia was maintained with isoflurane. One of three doses of atracurium was administered intravenously 30 minutes after induction: 0...

The phenomena of residual curarisation and recurarisation after the use of long-acting non-depolarising neuromuscular blocking drugs such as tubocurarine and pancuronium were well recognised 60 years ago. But the incidence seemed to decline with the introduction of atracurium and vecuronium. However, recently there have been an increasing number of reports of residual and recurrent neuromuscular block. Some of these reports are a result of inappropriate doses of rocuronium, sugammadex or both, together with inadequate neuromuscular monitoring...

PURPOSE: This study was performed to evaluate the effects of intraoperative intravenous lidocaine on postoperative delirium in elderly patients with hip fracture. PATIENTS AND METHODS: In total, 100 elderly patients undergoing hip fracture surgery were randomized to the lidocaine group (Group L) or saline (control) group (Group C). Before anesthetic induction, Group L received lidocaine at 1 mg/kg for more than 10 minutes followed by continuous infusion at 1.5 mg/kg/h until the end of surgery...

Generalized tetanus is still a global concern with a mortality rate of up to 50%, especially in low and middle-income countries. We reported a 23-year-old man from Afghanistan admitted to emergency department, with the chief complaint of generalized severe spasms and lockjaw. The patient had skin lesions and had never been vaccinated against tetanus. He intubated and admitted to the intensive care unit (ICU) with diagnose of severe generalized tetanus. After receiving tetanus immunoglobulin and intravenous metronidazole, a combination therapy of midazolam, propofol, atracurium, and morphine was administered...

BACKGROUND: Sugammadex reverses the neuromuscular blockade induced by rocuronium and vecuronium and is approved by the U.S. Food and Drug Administration for use in patients aged over 2 years. There is, however, a paucity of data regarding its dosing profile in infants and children younger than 2 years. AIMS: The aim of this study was to assess the risk of recurarization, or re-paralysis, in children under 2 years of age to increase awareness on the importance of appropriate neuromuscular blocked monitoring and reversal...

Background: Neuromuscular blocking agents are one of the few medication classes that have demonstrated a clinical benefit in patients with severe acute respiratory distress syndrome (ARDS). However, most literature utilized cisatracurium, and utilization of atracurium is limited to 1 small study. Objective: The purpose of this study was to provide further evidence comparing the safety and efficacy of atracurium versus cisatracurium for the treatment of ARDS. Methods: This multicenter, retrospective, observational cohort noninferiority study was conducted at 3 hospitals within a tertiary health care system...

OBJECTIVES: This study aimed to reduce the intensity of myoclonus movements by comparing the effectiveness of granisetron and sufentanil in reducing the intensity of etomidate-induced myoclonic movements. Etomidate-induced myoclonus occurs in up to 85% of patients under general anaesthesia. This type of myoclonus can induce significant clinical and economic problems in patients with special conditions. METHODS: This double-blind randomised clinical trial study consisted of 96 adult patients recruited between January and July 2021 from Mashhad University of Medical Sciences, Mashhad, Iran...

Background and aim Equipotent dose of atracurium and cis-atracurium has failed to show clinically equi-effective muscle relaxation actions required for laryngoscopy and endotracheal intubation (LETI) in adults. There needs to be more data on children. We aimed to compare the efficacy of equipotent atracurium and cis-atracurium for producing optimal LETI. We also compared the hemodynamic stability and side effects. Methods With approvals and informed consent, 104 children between three and 12 years were enrolled in the present randomized, double-blind, parallel-arm study...

Very little is known about the physiological role of nicotinic receptors in canine bladders, although functional nicotinic receptors have been reported in bladders of many species. Utilizing in vitro methods, we evaluated nicotinic receptors mediating bladder function in dogs: Control (9 female and 11 male normal controls, 5 sham-operated), Decentralized (9 females, decentralized 6-21 mo), and obturator-to-pelvic nerve transfer reinnervated (ObNT-Reinn; 9 females; decentralized 9-13 mo, then reinnervated with 8-12 mo recovery)...

A 4-year-old, entire, male, domestic long-haired cat was presented with an acute history of stranguria and dysuria and diagnosed with urolithiasis causing urethral obstruction. The patient was induced to general anaesthesia and several unsuccessful attempts to flush the uroliths retrogradely towards the bladder were made. An intraurethral administration of the neuromuscular blocking agent atracurium was performed as it has been reported to facilitate urethral catheterisation without any side effects. Respiratory arrest developed after 15 minutes from atracurium administration, which was promptly recognized and treated with mechanical ventilation...

BACKGROUND AND AIMS: Stagnara wake-up test is a simple reproducible neuromonitoring method during spinal surgery which replaces the evoked potential monitoring in the absence of neuromonitoring facilities. Dexmedetomidine (DEX) effect on the intraoperative wake-up test is still unclear. The present study was conducted to evaluate the effectiveness of DEX on the quality of wake-up test during spinal correction surgery. METHODS: A randomized controlled study was carried out over 62 patients randomized into two equal groups planned for elective minimally invasive corrective spine surgery...

BACKGROUND: General anesthesia leads to different effects depending on the drugs used (hypnosis, analgesia, muscle relaxation). While there are validated methods for clinical monitoring and control of hypnosis and muscle relaxation in routine anesthesia, the assessment of analgesia is still mainly based on the interpretation of clinical vital parameters, such as heart rate, blood pressure, perspiration or intraoperative movements of the patient. The present clinical study investigated whether the use of a so-called nociception monitor to record the intraoperative need for analgesics is superior to the previous analysis of vital parameters...

Nondepolarizing neuromuscular blocking agents are used frequently during ophthalmic surgery of dogs and cats. Residual neuromuscular block (NMB)-impaired neuromuscular function at recovery from anesthesia-is a main concern when these agents are used in small animals. In humans, residual NMB reduces the ability to protect the airway (swallow and cough) and increases the incidence of hypoxia and upper airway collapse after recovery from anesthesia. In dogs, impaired neuromuscular function of the larynx can be detected even after common indicators of neuromuscular function suggest that recovery from NMB is complete...

OBJECTIVE: To compare the effect of intra-cuff lidocaine versus alkalinized lidocaine in the prevention of post-operative sore throat. METHODS: The cross-sectional study was conducted from June 15 to July 15, 2019, at the Department of Anaesthesiology, Liaquat National Hospital and Medical College, Karachi, and comprised patients of either gender aged 15-50 years classified as American Society of Anaesthesiologist class 1-2 and undergoing general anaesthesia with endotracheal intubation expected to last more than one hour...

MRGPRX2, a G-protein-coupled-seven transmembrane domain receptor, is mainly expressed in mast cells and neurons and is involved in skin immunity and pain. It is implicated in the pathophysiology of non-IgE-mediated immediate hypersensitivity and has been related to adverse drug reactions. Moreover, a role has been proposed in asthma, atopic dermatitis, contact dermatitis, and chronic spontaneous urticaria. Although it has a prominent role in disease, its signaling transduction is poorly understood. This study shows that MRGPRX2 activation with substance P increased Lysyl t-RNA synthetase (LysRS) translocation to the nucleus...

Background Baska Mask (BM) is a third-generation supraglottic airway device with a self-inflating cuff. This study aimed to evaluate the efficacy of the BM compared to ProSeal laryngeal mask airway (PLMA) regarding insertion time, ease of insertion, and oropharyngeal seal pressure in patients undergoing elective surgeries under general anesthesia for less than two hours. Methods This prospective, randomized, double-blind comparative study was done on 64 patients randomly divided into two groups, with 32 patients in the PLMA group (Group A) and 32 in the BM group (Group B)...

BACKGROUND AND AIMS: Endotracheal intubation (ET) in infants is considered a challenging task over the decades. Infants have short safe apnoea time, and this difficulty has been vanquished to some extent by using the videolaryngoscopes (VLs), but there exists a dearth of research particularly in this vulnerable subset. Therefore, this trial was conducted to evaluate intubation times obtained with C-MAC VL and conventional Miller laryngoscopes in infants. METHODS: A total of 80 infants aged between 1 month and 1 year with American Society of Anesthesiologists physical status I-II requiring ET were randomised in two groups; the C-MAC VL or Miller laryngoscope ML...
