Development and evaluation of a point-of-care ultrasound curriculum for paramedics in Germany - a prospective observational study and comparison.

Background: Point-of-care ultrasound (POCUS) is steadily growing in use in prehospital emergency medicine. While currently used primarily by emergency physicians, POCUS could also be employed by paramedics to support diagnosis and decision-making. Yet to date, no paramedicine-targeted POCUS curricula exist in Germany.

[Recommendations of the new S1 guidelines on airway management].

The German guidelines for airway management aim to optimize the care of patients undergoing anesthesia or intensive care. The preanesthesia evaluation is an important component for detection of anatomical and physiological indications for difficult mask ventilation and intubation. If predictors for a difficult or impossible mask ventilation and/or endotracheal intubation are present the airway should be secured while maintaining spontaneous breathing.

German guidelines for airway management 2023.

The German airway management guidelines are intended to serve as an orientation and decision-making aid and thus contribute to the optimal care of patients undergoing anesthesiologic- and intensive medical care. As part of the pre-anesthesiologic evaluation, anatomical and physiological indications for difficult mask ventilation and intubation shall be evaluated. This includes the assessment of mouth opening, dental status, mandibular protrusion, cervical spine mobility and existing pathologies.

Study Design And Methods: An online survey was conducted among members of the German Society of Anesthesiology and Intensive Care.

Evaluation of the McGrath MAC and Macintosh laryngoscope for tracheal intubation in 2000 patients undergoing general anaesthesia: the randomised multicentre EMMA trial study protocol.

Introduction: The direct laryngoscopy technique using a Macintosh blade is the first choice globally for most anaesthetists. In case of an unanticipated difficult airway, the complication rate increases with the number of intubation attempts. Recently, McGrath MAC (McGrath) video laryngoscopy has become a widely accepted method for securing an airway by tracheal intubation because it allows the visualisation of the glottis without a direct line of sight.

Orogastric tube insertion using the new gastric tube guide: first experiences from a manikin study.

Background: Orogastric tube placement is a common procedure routinely used in clinical anesthesiology and intensive care medicine. Nevertheless high failure rates and severe complications have been reported. We conducted this study to evaluate if the usage of the new gastric tube guide would speed up the placement of orogastric tubes and ease the procedure.

Evaluation of the optimal cuff volume and cuff pressure of the revised laryngeal tube "LTS-D" in surgical patients.

Background: Recent case reports have indicated significant cuff overinflation when using the standard filling volume based on the manufacturer's recommendations in older models of laryngeal tubes. The aim of this study was to determine the minimum cuff pressure needed to perform standardized ventilation without leakage in the new, revised model of the laryngeal tube "LTS-D".

Methods: After ethical approval, LTS-D was placed for ventilation in 60 anesthetized patients.

LMA Supreme™ and Ambu® AuraGain™ in anesthetized adult patients: a prospective observational study.

Background: Second-generation laryngeal masks with gastric access are increasingly used in daily practice and expand the indications for laryngeal masks in the OR. Only limited data exist comparing different types of laryngeal masks. We investigated the second-generation laryngeal masks LMA Supreme™ and Ambu® AuraGain™ in a clinical setting.

Bonfils intubation fibrescope: use in simulation-based intubation training for medical students in comparison to MacIntosh laryngoscope.

Background: A variety of instruments are used to perform airway management by tracheal intubation. In this study, we compared the MacIntosh balde (MB) laryngoscope with the Bonfils intubation fibrescope as intubation techniques. The aim of this study was to identify the technique (MB or Bonfils) that would allow students in their last year of medical school to perform tracheal intubation faster and with a higher success probability.

[Hyperbaric therapy and diving medicine - diving medicine - present state and prospects].

The diving accident (decompression incident, DCI) occurs in the decompression phase of dives. The DCI can either be caused by an arterial gas embolism (AGE) subsequent to a pulmonary barotrauma or by the formation of inert gas bubbles subsequent to a reduction of ambient pressure during the ascent from depth. In contrast to the traditional assumption that decompression incidents only occur if decompression rules are neglected, recent data indicate that a vast amount of diving accidents occur even though divers adhered to the rules.

The novel intubating laryngeal tube (iLTS-D) is comparable to the intubating laryngeal mask (Fastrach) - a prospective randomised manikin study.

Background: Supraglottic devices are helpful for inexperienced providers who perform ventilation in emergency situations. Most supraglottic devices do not allow secondary tracheal intubation through the device. The novel intubating laryngeal tube (iLTS-D) and the intubating laryngeal mask (Fastrach) are devices that offer supraglottic ventilation and secondary tracheal intubation.
