Efficacy and Safety of Using High-Flow Nasal Oxygenation in Patients Undergoing Rapid Sequence Intubation
2017
Objective To assess the efficacy and safety of high-flow nasal oxygen (HFNO) therapy in patients undergoing rapid sequence intubation (RSI) for emergency abdominal surgery. Methods HFNO of 60 L.min-1 at an inspiratory oxygen fraction of 1 was delivered 4 min before laryngoscopy and maintained until the patient was intubated, and correct intubation was verified by the appearance of the end-tidal CO2 (EtCO2) waveform. Transcutaneous oxygenation (SpO2), heart rate and non-invasive mean arterial pressure were monitored at baseline (T0), after 4 min on HFNO (T1) and at the time of laryngoscopy (T2) and endotracheal intubation (ETI) (T3). An SpO2 of <3% from baseline was recorded at any sampled t…
Intubationsbedingungen nach Rocuronium und Succinylcholin
1996
OBJECTIVE Rocuronium is a new non-depolarising steroidal muscle relaxant with a short onset time. The present study was undertaken to compare intubating conditions as well as onset and clinical duration of a single dose of 0.6 mg/kg (2 x ED95) with a single dose of 1 mg/kg suxamethonium (3 x ED95). METHODS After obtaining informed consent and approval of the Ethics Committee, 40 adult patients (ASA I-III) participated in this study. After premedication with oxazepam, anaesthesia was induced with fentanyl and propofol and maintained with propofol, N2O and supplements of fentanyl as needed. Muscular relaxation was assessed by EMG recording of adductor pollicis muscle after supramaximal single…
Effect of depth of neuromuscular blockade on the abdominal space during pneumoperitoneum establishment in laparoscopic surgery.
2015
To evaluate the effect of neuromuscular blockade (NMB) upon the abdominal space during pneumoperitoneum establishment in laparoscopic surgery, comparing moderate NMB and deep NMB.Prospective, randomized, crossover clinical trial.Operating room.Seventy-six American Society of Anesthesiologists 1 to 2 patients scheduled for elective laparoscopic surgery.Two independent evaluations were performed at the establishment of pneumoperitoneum for a preset intraabdominal pressures (IAPs) of 8 and 12 mm Hg, both during moderate NMB (train-of-four count, 1-3) and deep NMB (posttetanic count,5). Rocuronium was used to induce NMB, and sugammadex was used for reversal.We evaluated (i) the volume of CO2 in…
Beeinflussung der Pharmakodynamik von Rocuronium durch Cimetidin
1996
Nach Gabe von Cimetidin kann die Wirkungszeit nichtdepolarisierender Muskelrelaxanzien verlangert sein. Wir untersuchten diesen Zusammenhang fur Rocuronium nach einer Einzeldosis von 400 mg Cimetidin intravenos im Vergleich mit einer Kontrollgruppe. Die Antwort des M. adductor pollicis nach Stimulation des N. ulnaris wurde elektromyographisch registriert. Die Anschlags- und Erholungszeiten sind in beiden Gruppen vergleichbar. Der fehlende Einflus von Cimetidin auf die neuromuskulare Blockade von Rocuronium konnte darauf hindeuten, das die Elimination von Rocuronium nicht nur in der Leber stattfindet. Eine mogliche direkte Beeinflussung der neuromuskularen Endplatte durch Cimetidin, wie sie …
Die Wirkung des Alters auf Anschlagszeit und Erholung nach Atracurium, Rocuronium und Vecuronium
1996
Bei alten Patienten kann die Wirkung von Muskelrelaxanzien verandert sein. Wir untersuchten diesen Zusammenhang an 108 Patienten dreier Altersgruppen, die randomisiert klinisch ubliche Intubationsdosen von Atracurium, Rocuronium und Vecuronium erhielten. Anschlagszeit und Erholung von der neuromuskularen Blockade wurden mit dem evozierten EMG des M. adductor pollicis nach Stimulation des N. ulnaris (Einzelreizung, 0,1 Hz) ermittelt. Die Anschlagszeiten sind in allen drei Altersgruppen vergleichbar, die Erholungszeiten bei den alten Patienten nach allen drei Relaxanzien verlangert. Die verlangerte Erholungszeit fur Rocuronium korreliert mit erhohten Werten der berechneten Kreatinin-Clearance…
The Hemodynamic Effects of Ephedrine on the Onset Time of Rocuronium in Pigs
2004
Several studies have found a correlation between the onset time of muscle relaxants, cardiac index, and muscle blood flow. Ephedrine increases these hemodynamic variables and shortens onset time of rocuronium in humans. Our aim in this animal study was to determine the effect of ephedrine on the onset time of rocuronium, cardiac index, and muscle blood flow after administration of thiopental. At predefined measuring points, mean arterial blood pressure and cardiac index were measured invasively and onset time was determined mechanomyographically. Twenty-four pigs were randomly assigned to three groups. Group I received etomidate and subsequently rocuronium (2 x 95% effective dose). Instead …
Influence of depth of neuromuscular blockade on surgical conditions during low-pressure pneumoperitoneum laparoscopic cholecystectomy: A randomized b…
2017
Abstract Study objective To evaluate the influence of neuromuscular blockade (NMB) on surgical conditions during low-pressure pneumoperitoneum (8mmHg) laparoscopic cholecystectomy (LC), while comparing moderate and deep NMB. Secondary objective was to evaluate if surgical conditions during low-pressure pneumoperitoneum LC performed with deep NMB could be comparable to those provided during standard-pressure pneumoperitoneum (12mmHg) LC. Design Prospective, randomized, blinded clinical trial. Setting Operating room. Patients Ninety ASA 1–2 patients scheduled for elective LC. Interventions Patients were allocated into 3 groups: Group 1: low-pressure pneumoperitoneum with moderate-NMB (1–3 TOF…
Review of difficult airway management in thoracic surgery
2018
The management of difficult airway (DA) in thoracic surgery is more difficult due to the need for lung separation or isolation and frequent presence of associated upper and lower airway problems. We performed an article review analysing 818 papers published with clinical evidence indexed in Pubmed that allowed us to develop an algorithm. The best airway management in predicted DA is tracheal intubation and independent bronchial blockers guided by fibroscopy maintaining spontaneous ventilation. For unpredicted DA, the use of videolaryngoscopes is recommended initially, and adequate neuromuscular relaxation (rocuronium/sugammadex), among other maneuvers. In both cases, double lumen tubes shou…
Repeated sugammadex reversal of muscle relaxation during lumbar spine surgery with intraoperative neurophysiological multimodal monitoring
2016
Intraoperative neurophysiological monitoring during spine surgery is usually acomplished avoiding muscle relaxants. A case of intraoperative sugammadex partial reversal of the neuromuscular blockade allowing adequate monitoring during spine surgery is presented. A 38 year-old man was scheduled for discectomy and vertebral arthrodesis throughout anterior and posterior approaches. Anesthesia consisted of total intravenous anesthesia plus rocuronium. Intraoperatively monitoring was needed, and the muscle relaxant reverted twice with low dose sugammadex in order to obtain adequate responses. The doses of sugammadex used were conservatively selected (0.1 mg/kg boluses increases, total dose neede…
Economic aspects of different muscle relaxant regimens.
2000
Objective At a time of cost reduction in medical care efforts to manage the ever-increasing costs of new pharmaceutical drugs become increasingly important. Costs of four different muscle relaxant regimens including the new intermediate-acting neuromuscular blocking drugs (NMBD) cisatracurium and rocuronium will be analyzed. Methods Eighty patients undergoing laparoscopic cholecystectomy were prospectively studied. All patients received standardized general anaesthesia with desflurane/fentanyl. Muscle relaxation was achieved with atracurium, cisatracurium, vecuronium, or rocuronium with 20 patients in each group. Intraoperatively muscle relaxants were added to maintain two twitches of the t…
