Determination of meropenem in endotracheal tubes by in-tube solid phase microextraction coupled to capillary liquid chromatography with diode array d…

2017

Meropenem is a widely used antimicrobial for the treatment of infections associated with the use of invasive medical devices in intensive care unit patients. These treatments are not always effective, in fact, in-vitro studies have demonstrated the difficulty of antimicrobials to penetrate into the biofilm, however in-vivo studies of the effect of these compounds is a trend, mostly because of the complexity of pulmonary samples extracted from ETTs. Therefore, the objective of this study was to evaluate in-tube solid phase microextraction (in-tube SPME) coupled to capillary liquid chromatography (CapLC) with DAD to determine meropenem in Errs in order to estimate the penetration capability i…

Reflexionsakustische Lagebestimmung von Trachealkanülen

1997

Non-invasive acoustic airway monitoring was evaluated in an experimental study. Recording amplitude and travel time of acoustic pulse response, an area-distance function of the cross sectional dimensions of the endotracheal tube and the adjacent airway was calculated to obtain an acoustic pattern of the airway. Measurements on models and excised human cadaver lungs were performed to discover whether displacement or obstruction of the artificial airway can be detected in the acoustic equivalent. Regression analysis revealed a close correlation between displacement of tracheostomy tubes and the shifting of the acoustic area-distance function (corr. coeff. 0.97-1). Dispersion analysis confirme…

The EasyTube for Airway Management in Emergencies

2005

The EasyTube (EzT) is a new sterile, disposable airway device approved by the European Union in February 2003 and by the U.S. Food and Drug Administration in January 2005. The two-lumen design of the EzT enables it to be used as an endotracheal tube or as a supraglottic emergency airway.To report the preliminary experiences with the EzT airway device in prehospital and in-hospital emergency airway management procedures.All airway management procedures involving the EzT were recorded for a period of 18 months.The EzT was successfully used to intubate 15 patients with unanticipated airway difficulties during either anesthesia induction or prehospital airway management. In all patients, the Ez…

Zugangswege f�r die Medikamentenapplikation bei Herzkreislaufstillstand

1996

Selecting a route for drug administration during CPR requires consideration of the speed with which access can be obtained, the technical difficulties involved in performing the procedure, the associated risk of complications, delays in drug delivery to the central circulation, and the duration of effective drug levels following injection. The peripheral venous route is the safest method, and drug delivery can be enhanced by a fluid bolus after injection of the medication. The circulation time is shortest after central venous injection, but there is some risk of complications. The femoral route is associated with a high incidence of unsuccessful catherization. The endotracheal tube provides…

Making endotracheal intubation easy and successful, particularly in unexpected difficult airway.

2014

Background: Difficult intubation, most often due to poor view of the vocal cords on laryngoscopy is an intermittent and often challenging problem for clinically practicing anesthesiologists, maxillofacial surgeons, ear nose, and throat (ENT), emergency, and critical care physicians. Purpose: We present a new approach for facilitating difficult intubation and evaluate its efficacy in a retrospective observational study. Settings and Design: Operating room, emergency department, intensive care unit (ICU), retrospective observational study. Materials and Methods: A semirigid 5.6 Rusch tracheal tube introducer (bougie) with its soft tip protruding at least 6 cm (=4 digits) beyond the distal end…

Influence of different interfaces on synchrony during pressure support ventilation in a pediatric setting: a bench study

2015

BACKGROUND: In adults and children, patient-ventilator synchrony is strongly dependent on both the ventilator settings and interface used in applying positive pressure to the airway. The aim of this bench study was to determine whether different interfaces and ventilator settings may influence patient-ventilator interaction in pediatric models of normal and mixed obstructive and restrictive respiratory conditions. METHODS: A test lung, connected to a pediatric mannequin using different interfaces (endotracheal tube [ETT], face mask, and helmet), was ventilated in pressure support ventilation mode testing 2 ventilator settings (pressurization time [Timepress]50%/cycling-off flow threshold [T…

Anestesisykepleieres metoder for å kontrollere cufftrykk – en observasjonsstudie

2021

Bakgrunn: Forskning viser at pasienter i generell anestesi som har fått sine luftveier sikret med en larynxmaske eller en endotrakealtube opplever postoperative pharyngolaryngeale komplikasjoner. Et kontrollert cufftrykk har vist reduksjon i komplikasjoner.
 Hensikt: Hensikten med studien var å undersøke hvilke metoder anestesisykepleiere bruker for å kontrollere cufftrykk, og hvilke begrunnelser de har for å bruke cufftrykkmanometer.
 Metode: Totalt 45 anestesisykepleiere ble observert når de kontrollerte cufftrykket i en endotrakealtube og en larynxmaske. Anestesisykepleierne ble i tillegg spurt om hvilke begrunnelser de hadde for å bruke eller ikke bruke cufftrykkmanometer.&#x0…

Ein Mikro-Atemstromventil für spontan atmende narkotisierte Kleintiere - A Respiratory Micro-Valve for Spontaneously Breathing Anaesthetized Small An…

1994

For the accurate functional analysis of the gas exchange in the lungs or evaluation of artificial oxygen carriers in spontaneously breathing anaesthetized small animals, we developed a new respiratory micro-valve. The body of the valve is made of aluminium, and the flaps are made of silicone rubber. The maximum flow rate in a rat measured with a pneumotachograph and the micro-valve was an average of 19.9 ml/s during inspiration, and 17.8 ml/s during expiration. The pressure measured in the tracheal tube was -0.85 during inspiration, and +0.39 cm H2O during expiration; the end-expiratory pressure in the tube was zero. In two experiments with anaesthetised rats lasting 4-5 hours, ventilation,…

Usage of a semi-rigid intubation endoscope is not superior to a video laryngoscope. A prospective, randomised, controlled trial comparing the SensaSc…

2018

Abstract Introduction Numerous guidelines and techniques have been developed to manage difficult airways and to prevent problems in airway management. To achieve an optimal view of the glottis, various video laryngoscopes and video stylets have been developed and introduced in clinical anaesthesia. The aim of this study was to compare the time to place the tracheal tube (TT) with the McGrath™ Series 5 (McG; Medtronic Dublin, Ireland) and the semi-rigid intubation endoscope SensaScope™ (Sc; Acutronic Medical Systems AG, Hirzel, Switzerland) in elective surgery patients. Methods With the approval of the local ethics committee, patients were recruited for this prospective, randomised clinical …

Purpose It is generally accepted that using a video laryngoscope is associated with an improved visualization of the glottis. However, correctly placing the endotracheal tube might be challenging. Channeled video laryngoscopic blades have an endotracheal tube already pre-loaded, allowing to advance the tube once the glottis is visualized. We hypothesized that use of a channel blade with pre-loaded endotracheal tube results in a faster intubation, compared to a curved Macintosh blade video laryngoscope. Methods After ethical approval and informed consent, patients were randomized to receive endotracheal Intubation with either the King Vision® video laryngoscope with curved blade (control) or…
