Anestesisjuksköterskans upplevelse av att använda endotrachealtub och larynxmask vid plötsligt hjärtstopp / The Nurse anesthesia’s experience of using endotracheal tube and laryngeal mask in case of sudden cardiac arrest

Mases, Johanna, Ahlskog, Oskar January 2022 (has links)
Introduktion: Anestesisjuksköterskor arbetar inom flera olika delar av sjukvården. Tack vare deras kunskaper om luftvägar och omhändertagande av kritiskt sjuka patienter så anställs anestesisjuksköterskor inom olika prehospitala verksamheter så som exempelvis resursenheter. Vid plötsliga hjärtstopp är upprättandet av en fri luftväg kritiskt. Detta görs vanligen genom användandet av olika medicintekniska hjälpmedel som larynxmask eller endotrachealtub. De respektive hjälpmedlen har olika styrkor och svagheter som är väl studerade, men upplevelser av att använda dessa metoder finns det lite forskning om. Syfte: Syftet med studien var att studera anestesisjuksköterskans upplevelser av att använda larynxmask och endotrachealtub vid plötsliga hjärtstopp utanför sjukhuset. Metod: En kvalitativ induktiv enkätstudie med öppna semistrukturerade frågor genomfördes för att fånga användarnas upplevelser av skillnader mellan dessa metoder av luftvägshantering. 14 anestesisjuksköterskor med minst två års erfarenhet samt erfarenhet av att arbeta prehospitalt deltog i studien. Deltagarna arbetar i tre regioner vilka har stora skillnader i resurser och arbetsrutiner. Resultat: Larynxmask var mest använt, trots att nästan alla deltagare föredrog att ha patienten intuberad. Orsaken till att laynxmasken användes trots att deltagarna föredrog att patienten skulle ha en endotrachealtub varierade något men hade flera gemensamma faktorer så som tidsåtgång och enkel användning. / Introduction: Nurse anesthesias work in different parts of healthcare. In various prehospital activities and different resource units these specialist nurses are often hired for their knowledge of the airways and critical patients. In case of sudden cardiac arrest, the establishment of a free airway is critical. This is usually done using various medical aids such as a laryngeal mask or endotracheal tube. These have their different strengths and weaknesses that are well studied, but there is little research on experiences of using these methods. Aim: The aim of the study was to study anesthesia nurses' experiences of using a laryngeal mask and endotracheal tube in sudden cardiac arrest outside the hospital. Method: A qualitative inductive survey with open semistructural questions, was done to capture the users’ experiences of the differences between these methods of airway management. This study included 14 nurse anesthetists, with at least 2 years of experience and experience of working in a prehospital setting. Participants from three regions participated, those regions differ in resources and ways of working routines. Result: The laryngeal mask is most commonly used, even though almost all participants prefer to have an intubated patient. The reasons for that varies between the participants but have several common factors such as time of application and ease of use.

A comparison of airway devices for the simulated entrapped patient

Pap, Robin January 2012 (has links)
A research report submitted in partial fulfilment of the requirements for the degree Master of Science in Medicine in the Field of Emergency Medicine in the Division of Emergency Medicine, University of the Witwatersrand / Introduction: Control over the patient bears time-critical importance in emergency medicine. In the entrapment situation after a Motor Vehicle Collision (MVC), emergency care including airway management may need to be initiated before extrication and thus with restricted access. Objective: This manikin study aimed at answering the question of which advanced airway device can be inserted the fastest and most reliably by paramedics in the simulated entrapped patient. Methods: Paramedics were asked to insert four airway devices (endotracheal tube with the Macintosh laryngoscope, endotracheal tube with the Airtraq® optical laryngoscope, Laryngeal Mask Airway - SupremeTM, and Laryngeal Tube Suction - DisposableTM) in randomised order into a manikin seated in the driver seat of a light motor vehicle. Time to first successful ventilation and number of attempts required for successful insertion were measured. Following each insertion, participants were asked by means of a questionnaire to rate the degree of insertion difficulty (scale 1 – 10) and provide reasons for this rating. Finally, participants were asked which device they preferred and why. Results: Prospectively collected data from 26 paramedics were analysed. The LMA-SupremeTM had the shortest mean time to first successful ventilation (16.7 seconds (CI [0.95]; 14.9 - 18.6)), followed by the LTS-DTM (19.4 seconds (CI [0.95]; 18.0 - 20.8)), ETI using the Macintosh laryngoscope (37.7 seconds (CI [0.95]; 31.8 - 43.5)) and ETI using the Airtraq® (41.2 seconds (CI [0.95]; 36.7 - 45.6)). Both face-to-face ETI with the Macintosh laryngoscope and the insertion of the LMA-SupremeTM had 100% first-attempt success. Five participants required a second attempt to successfully intubate the manikin using the Airtraq® and one participant had to re-insert the LTS-DTM for correct placement. In terms of insertion difficulty, the LMA-SupremeTM received the lowest mean score (1.7/10 (CI [0.95]; 1.2 - 2.1)) followed by the LTS-DTM (2.5/10 (CI [0.95]; 1.8 – 3.2)), face-to-face ETI using the Macintosh laryngoscope (3.7/10 (CI [0.95]; 2.9 - 4.5)), and ETI with the Airtraq® (4.5/10 (CI [0.95]; 3.7 - 5.3)). Most participants chose the Macintosh laryngoscope for ETI as their preferred device (10/26; 38%) followed closely by the LMA-SupremeTM (9/26; 35%). These participants stated clinical experience and ease of insertion respectively as the primary reasons for their preference. Conclusion: Besides ETI, Supraglottic Airway Devices are beneficial alternative airway devices to be considered by paramedics in the entrapped patient after a MVC. The LMA-SupremeTM was the fastest and least difficult airway device to insert. Face-to-face endotracheal intubation with the Macintosh laryngoscope remains an important definitive airway that was shown to be performed competently by participating paramedics. The Airtraq® can be used for face-to-face ETI and enables improved laryngoscopy.
