Purpose: To report a case of temporary bilateral corneal denting in a patient who underwent cardiovascular surgery under general anesthesia. Observations: A 71-year-old male with no history of ophthalmological disease experienced bilateral corneal denting immediately after undergoing surgery for aneurysm of the thoracic aorta under general anesthesia. Anesthesia was induced with propofol and maintained with rocuronium bromide and remifentanil hydrochloride. The initial examination revealed significant denting on the surface of both the corneas and ocular hypotension...

During neuromuscular monitoring, repeated electrical stimulation evokes muscle responses of increasing magnitude ('staircase phenomenon', SP). We aimed to evaluate whether SP affects time course and twitches' values of an acceleromyographic assessed neuromuscular block with or without previous tetanic stimulation. Fifty adult patients were randomized to receive a 50 Hz tetanic stimulus (S group) or not (C group) before monitor calibration. After 20 min of TOF ratio (TOFr) stimulation rocuronium was administered...

BACKGROUND: The duration of rocuronium in patients with BMI more than 30 kg m is prolonged. Whether the reverse is true when BMI is less than 18.5 kg m is unclear. OBJECTIVE: The objective of this study was to investigate whether a BMI less than 25 kg m affects the duration of rocuronium in doses adjusted for actual body weight. DESIGN: A prospective, observational, single-centre study. SETTING: The operating room of a teaching hospital from 1 June 2008 to 30 June 2015...

STUDY OBJECTIVE: Although both succinylcholine and rocuronium are used to facilitate emergency department (ED) rapid sequence intubation, the difference in intubation success rate between them is unknown. We compare first-pass intubation success between ED rapid sequence intubation facilitated by succinylcholine versus rocuronium. METHODS: We analyzed prospectively collected data from the National Emergency Airway Registry, a multicenter registry collecting data on all intubations performed in 22 EDs...

Tracheal intubation without neuromuscular blockade may be associated with worse intubating conditions and increased laryngeal morbidity. We hypothesised that tracheal intubation using the McGRATH™ MAC videolaryngoscope would not increase postoperative hoarseness, even without neuromuscular blockade. In this prospective, randomised, parallel-group, double-blind, non-inferiority trial, 248 patients were randomly assigned to tracheal intubation with or without neuromuscular blockade using rocuronium. Hoarseness and sore throat were evaluated at 24 h and 48 h postoperatively...

Objective This study was performed to determine the effect of the remifentanil dose on the onset time of rocuronium with electromyography. Methods This retrospective comparative study included 75 patients undergoing general anesthesia for elective surgery. Patients received lidocaine (40 mg) and propofol (2 mg/kg) followed by rocuronium (0.6 mg/kg) with either saline infusion (Group S), remifentanil at 0.5 µg/kg/minute (Group R 0.5), or remifentanil at 1.0 µg/kg/minute (Group R 1.0). Neuromuscular block was monitored by train-of-four (TOF) electromyography, and the times taken to reach TOF 0 and TOF ratio (TOFR) 25% were recorded...

Background: Non-intubated thoracoscopic surgery can be performed under sedation using adjuvant regional anesthesia, however, the benefits of non-intubated thoracoscopic surgery under sedation have not yet been completely verified. In this study, we compare the perioperative safety and pain complaints of sedation without intubation in thoracoscopic bullectomy with that of conventional general anesthesia with double-lumen intubation and mechanical ventilation. Methods: Forty-one patients with primary spontaneous pneumothorax who were scheduled for thoracoscopic bullectomy were enrolled in this study...

INTRODUCTION: Minimally invasive cardiac surgery (MICS), via minithoracotomy, is thought to be a fast track to extubation and recovery after surgery. Chronic pain, due to intercostal nerve injury, develops in up to 50% of postthoracotomy patients.A number of regional anaesthesia and analgesia techniques may be employed, and the anaesthesiologists play a key role in facilitating optimal outcomes after surgery. METHODS: We report a case of postoperative pain management with a local anesthetic infiltration for MICS...

Congenital fibre type disproportion (CFTD) is a rare type of myopathy that is characterised by muscle weakness and hypotonia during childhood. Clinical features include motor delay, feeding difficulties, limb weakness, joint contractures, and scoliosis. A report is presented of the anaesthetic management of a 3-year-old girl with CFTD myopathy associated with a mutation of the TPM3 gene, scheduled for adenotonsillectomy because of obstructive sleep apnoea hypopnoea syndrome (OSAHS). The main concerns were the possible susceptibility to malignant hyperthermia, the risk of anaesthesia-induced rhabdomyolysis, a greater sensitivity to non-depolarising muscle relaxants, and the presence of OSAHS...

Background: Several types of receptors are found at neuromuscular presynaptic membranes. Presynaptic inhibitory A1 and facilitatory A2A receptors mediate different modulatory functions on acetylcholine release. This study investigated whether adenosine A1 receptor agonist contributes to the first twitch tension (T1) of train-of-four (TOF) stimulation depression and TOF fade during rocuronium-induced neuromuscular blockade, and sugammadex-induced recovery. Methods: Phrenic nerve-diaphragm tissues were obtained from 30 adult Sprague-Dawley rats...

Background: Neuromuscular blocking agents (NMBAs) are a leading cause of perioperative anaphylaxis. However, the performance of systematic screening skin tests to detect reactions for NMBAs prior to general anesthesia is not recommended. We retrospectively examined intradermal tests (IDTs) for rocuronium and cisatracurium in patients with a history of allergy. Methods: We reviewed the records of patients who underwent IDTs for NMBAs between January 1 and December 31, 2016...

Muscle ischaemia is frequently induced intraoperatively by i.e. a surgical tourniquet or during the re-grafting phase of a free muscle transplant. The resulting muscle cell damage may impact on postoperative recovery. Neuromuscular paralysis may mitigate the effects of ischaemia. After ethics approval, 25 male Sprague-Dawley rats were anaesthetized and randomly assigned to 1 of 4 groups: Sham operation, treatment with normal saline, treatment with rocuronium (muscle relaxant) 0.6 or 1 mg kg-1 , respectively...

Background: The onset time of neuromuscular blockade is a crucial time associated with the risk of hypoxia and pulmonary aspiration. Various strategies have been undertaken to shorten this onset time. Therefore, we investigated the effects of bolus of 20 ml saline followed by limb elevation after administration of rocuronium in a dose of 0.6 mg/kg to study the onset time. Methodology: Thirty patients were randomly allocated to the bolus saline group or control group...

BACKGROUND: The concept of the effect-site concentration of anesthetic agents is important. The effect compartment model can be explained using the concepts of effect-site concentration and effect-site equilibration rate constant ( k e0 ). This study confirms that the time-to-peak effect ( tpe ) can be measured easily in clinical practice by applying a priming dose and train-of-four (TOF) during general anesthesia induction, and k e0 can be calculated from the tpe of the four muscle relaxants that are commonly used in general anesthesia...

Background: Duchenne muscular dystrophy (DMD) is an X-linked recessive skeletal muscle myopathy which is caused by mutations in the dystrophin gene. Lack of dystrophin also results to cardiomyopathy, which raises significantly the stroke risk in DMD-patients. However, data about therapeutic opportunities in the acute setting are scarce in literature. So far, only two cases receiving IV thrombolysis are described, one of them with fatal outcome. Method: Case report of a case of successful mechanical thrombectomy (MTE) in an acute ischemic stroke (AIS) patient with DMD and associated dilatative cardiomyopathy...
