OBJECTIVE: In our study, we aimed to compare the effect of standard rapid sequence intubation protocol and the application of rocuronium priming technique on the procedure time and hemodynamic profile. METHODS: Patients who applied to the emergency department and needed rapid sequence intubation were included in our study, which we conducted with a randomized controlled design. Randomization in the study was made according to the order of arrival of the cases. Rapid sequence intubation was performed in the standard group...

Introduction Magnesium is recognized for its ability to reduce the onset time of rocuronium while simultaneously extending its duration of action. This study aims to assess the efficacy of magnesium pre-treatment in decreasing the onset time with two different doses of rocuronium in patients undergoing rapid sequence intubation. Materials and methods This randomized prospective double-blind clinical study involved 50 patients classified as American Society Of Anesthesiologists (ASA) I/II, with no preoperative indications of difficult intubation, undergoing elective surgery under general anesthesia...

We present a case in which intramuscular rocuronium was used successfully to treat laryngospasm in a pediatric patient. An 11-month-old infant weighing 9.7 kg was scheduled for an elective laparoscopic inguinal hernia repair surgery. Anesthesia was induced with oxygen, nitrous oxide, and sevoflurane. After loss of consciousness, mask ventilation became impossible, and laryngospasm was suspected. Intravenous access was attempted without success; as there was no immediate access to succinylcholine, rocuronium 10 mg (1...

PURPOSE: Postoperative shoulder pain is a common problem after laparoscopic surgery. This study aimed to investigate the association between operative side and postoperative shoulder pain following urologic laparoscopic surgery performed in the lateral recumbent position. METHODS: This was a retrospective cohort study conducted at a single tertiary care center. A total of 506 patients who underwent urologic laparoscopic surgery (including adrenalectomy, radical nephrectomy, partial nephrectomy, and pyeloplasty) between January 2010 and December 2019 were included...

BACKGROUND: The incidence of arterial hypotension during induction of general anesthesia is influenced by the method of propofol administration, but there is a dearth of randomized clinical trials comparing bolus injection and target-controlled infusion in relation to arterial hypotension. This study seeks to compare the incidence of arterial hypotension between these two methods of propofol administration. METHODS: This prospective, randomized, single-center, non-blinded study included 60 patients (aged 35 to 55-years), classified as ASA physical status I or II, who were undergoing non-cardiac surgeries...

Introduction Residual neuromuscular block, defined as a quantitatively measured train-of-four ratio (TOFr) <0.9, is common postoperatively. Using a pragmatic trial design, we hypothesized that qualitative and/or clinical assessment of neuromuscular block would inadequately detect residual block following antagonism with neostigmine or sugammadex. Method After IRB approval and written informed consent, 74 children (aged 2-17 years), undergoing elective surgery and receiving rocuronium, were prospectively enrolled in the study at Children's Hospital Colorado and Children's Healthcare of Atlanta...

AIMS: Residual neuromuscular blockade has been linked to pulmonary complications in the postoperative period. This study aimed to determine whether sugammadex was associated with a lower risk of postoperative pulmonary complications (PPCs) compared with neostigmine. METHODS: This retrospective cohort study was conducted in a tertiary academic medical center. Patients ≥18 year of age undergoing noncardiac surgical procedures with general anesthesia and mechanical ventilation were enrolled between January 2019 and September 2021...

BACKGROUND: Adolescent Idiopathic Scoliosis (AIS) affects 2%-4% of the general pediatric population. While surgical correction remains one of the most common orthopedic procedures performed in pediatrics, limited consensus exists on the perioperative anesthetic management. AIMS: To examine the current state of anesthetic management of typical AIS spine fusions at institutions which have a dedicated pediatric orthopedic spine surgeon. METHODS: A web-based survey was sent to all members of the North American Pediatric Spine Anesthesiologists (NAPSA) Collaborative...

OBJECTIVE: The aim of this study was to document ophthalmic examination findings and provide reference values for ocular examinations and diagnostics in clinically normal Western tiger salamanders (Ambystoma mavortium) and to evaluate the mydriatic effect of a topical rocuronium bromide and identify any adverse effects. ANIMALS STUDIED: Sixteen Western tiger salamanders. PROCEDURE: A complete ophthalmic examination, including intraocular pressure via rebound tonometry [iCare® TonoVet (dog-setting) or iCare® TonoVet Plus (dog-setting)], and fluorescein and Rose Bengal stains, was performed...

The development of artificial receptors that combine ultrahigh-affinity binding and controllable release for active guests holds significant importance in biomedical applications. On one hand, a complex with an exceedingly high binding affinity can resist unwanted dissociation induced by dilution effect and complex interferents within physiological environments. On the other hand, stimulus-responsive release of the guest is essential for precisely activating its function. In this context, we expanded hydrophobic cavity surface of a hypoxia-responsive azocalix[4]arene, affording Naph-SAC4A...

INTRODUCTION: To evaluate chemical stability and physical compatibility when combining fentanyl, rocuronium, and atropine in a fixed ratio to support intramuscular drug delivery during fetal intervention and surgery. METHODS: A highly concentrated combination of fentanyl, rocuronium, and atropine was created based on common prescribing practices at a maternal fetal care center. Chemical stability testing was completed using liquid chromatograph mass spectrometry-mass spectrometry (LC/MS-MS) to detect and quantitate atropine, rocuronium, and fentanyl, with fentanyl-d5 being an internal standard at 6-, 12, 24-, and 36-hours following sample preparation...

Sugammadex, marketed as Bridion™, is an approved cyclodextrin (CD) based drug for the reversal of neuromuscular blockade in adults undergoing surgery. Sugammadex forms an inclusion complex with the neuromuscular blocking agent (NMBA) rocuronium, allowing rapid reversal of muscle paralysis. In silico methods have been developed for studying CD inclusion complexes, aimed at accurately predicting their structural, energetic, dynamic, and kinetic properties, as well as binding constants. Here, a computational study aimed at characterizing the sugammadex-rocuronium system from the perspective of docking calculations, free molecular dynamics (MD) simulations, and biased metadynamics simulations with potential of mean force (PMF) calculations is presented...

The binding affinity of pillar[6]MaxQ toward a panel of neuromuscular blockers and neurotransmitters was measured in phosphate buffered saline by isothermal titration calorimetry and 1 H NMR spectroscopy. In vivo efficacy studies showed that P6MQ sequesters rocuronium and vecuronium and reverses their influence on the recovery of the train-of-four (TOF) ratio.

BACKGROUND: Residual neuromuscular blockade (rNMB) remains a persistent and preventable problem, with serious risks. METHODS: Our objective was to describe and assess patterns in the use of neuromuscular blocking agents (NMBAs), neuromuscular transmission (NMT) monitoring, and factors associated with the use of sugammadex. We performed a retrospective, observational cohort study based on electronic medical records in a large teaching hospital in the Netherlands that introduced an integrated NMT monitoring module with automatic recording in 2017...

BACKGROUND: Awake craniotomy (AC) is a neurosurgical method for the resection of brain lesions located in eloquent areas to achieve maximal and safe resection. A patient's arousal quality is essential for the success of the operation. This study compared the arousal time and quality after AC achieved by 2 different drug combinations: rocuronium with sugammadex and propofol with remifentanil. METHODS: This prospective, randomized, controlled trial included 42 adult patients undergoing AC with a laryngeal mask, who were randomly assigned to either a rocuronium-sugammadex group (RS; n = 21) or a propofol-remifentanil without muscle relaxant group (nRS; n = 21)...

BACKGROUND AND OBJECTIVE: Neuromuscular blocking agents are routinely used in laparoscopic surgery to optimize operative conditions. We compared the effect of a deep and moderate neuromuscular blockade (NMB) on surgical conditions and postoperative outcomes in children undergoing major laparoscopic surgery. METHODS: Sixty children aged 2-14 years scheduled to undergo major laparoscopic surgery were randomly allocated to deep (post-tetanic count 1-2 twitches) or moderate (train-of-four 1-2 twitches) NMB groups...

OBJECTIVE: This retrospective observational study aimed to investigate the effect of different doses of sugammadex used in reversing neuromuscular blockade in electroconvulsive therapy (ECT) procedures on patient recovery and hemodynamic measurements. METHODS: Anesthesia induction was performed using propofol (1 mg/kg) and rocuronium (0.4 mg/kg). Patients were classified into group 2 (2 mg/kg) and group 3 (3 mg/kg) according to the dose of sugammadex used to reverse neuromuscular blockade...

BACKGROUND: While awake, flexible bronchoscopic intubation has long been considered the gold standard for managing anticipated difficult airways, the videolaryngoscope has emerged as a viable alternative. In addition, the decision to perform awake intubation or to proceed with airway management after induction of general anesthesia should be grounded in a comprehensive assessment of risks and benefits. CASE PRESENTATION: A 41-year old female patient was scheduled for excision of bilateral, mobile, and pedunculated masses on both aryepiglottic folds, which covered almost the entire upper part of the glottis...

BACKGROUND: Perioperative anaphylaxis is rare but is associated with significant morbidity. This complication has been well described in France by the GERAP (Groupe d'Etude des Réactions Anaphylactiques Périopératoires), a network focused on its study. The epidemiology of perioperative anaphylaxis is evolving, influenced by environmental factors and clinical practice. The aim of this study was to update the epidemiology of perioperative anaphylaxis in France. METHODS: This multicentre retrospective study was performed in 26 allergy clinics of the GERAP network in 2017-8...

BACKGROUND: Deep neuromuscular blockade (NMB) has benefits in various surgical procedures, however, precise quantitative neuromuscular monitoring is crucial for its proper maintenance and recovery. Neuromuscular blocking agent dosage relies on actual body weight (ABW), but this varies among individuals. Therefore, this study hypothesizes that there is a correlation between the rocuronium requirement for deep NMB and muscle mass ratio measured by bioelectric impedance analysis. METHODS: Ninety adult female patients undergoing laparoscopic operation were enrolled in this study...
