Postoperativ halssmärta (POST) är en mycket vanlig komplikation hos patienter som genomgått generell anestesi med intubation.  POST anses av anestesipersonal vara en relativt lindrig komplikation. Patienter upplever det dock som ett stort problem och därför bör det undvikas. Syftet med denna litteraturstudie var att undersöka vad anestesisjuksköterskor kan göra för att förebygga POST som komplikation hos patienter som genomgått generell anestesi med intubation. Examensarbetet är en integrativ litteraturstudie som innefattar tolv globala studier. Litteraturstudiens resultat visar att det finns flera farmakologiska och icke farmakologiska metoder som kan förebygga POST. Lokal behandling med kortikosteroider och NSAID-preparat har förebyggande effekt på POST. Icke farmakologiska interventioner som konformad kuff, substanser som lakritslösning, magnesium och zink lindrar. Vissa studier finner att kortikosteroider och lidokain kan öka förekomsten av POST. I nuläget kan resultatet inte tillämpas av anestesisjuksköterskor då resultaten är tvetydiga och inte kan utföras utan ordination av anestesiolog. Vidare forskning inom området med inriktning på omvårdnad är av yttersta vikt.

Background: Laryngospasm is a common and often serious adverse respiratory event encountered during anesthetic care of children. We examined, in a case control design, the risk factors for laryngospasm in children. Material and Methods: The records of 130 children identified as having experienced laryngospasm under general anesthesia were examined. Cases were identified from those prospectively entered into the Mayo Clinic performance improvement database between January 1, 1996 and December 31, 2005. Potential demographic, patient, surgical and anesthetic related risk factors were determined in a 1 : 2 case-control study. Results: No individual demographic factors were found to be significantly associated with risk for laryngospasm. However, multivariate analysis demonstrated significant associations between laryngospasm and intercurrent upper respiratory infection (OR 2.03 P = 0.022) and the presence of an airway anomaly (OR = 3.35, P = 0.030). Among those experiencing laryngospasm during maintenance or emergence, the use of a laryngeal mask airway was strongly associated even when adjusted for the presence of upper respiratory infection and airway anomaly (P = 0.019). Ten patients experienced postoperatively one or more complications whereas only three complications were observed among controls (P = 0.008). No child required cardiopulmonary resuscitation and there were no deaths in either study cohort. Conclusions: In our pediatric population, the risk of laryngospasm was increased in children with upper respiratory tract infection or an airway anomaly. The use of laryngeal mask airway was found to be associated with laryngospasm even when adjusted for the presence of upper respiratory tract infection and airway anomaly.

Introduction: Adequate post-intubation sedation and analgesia (PISA) practices are important in the pre-hospital setting where vibration and noise of the transport vehicle may contribute to anxiety and pain in the patient. Inadequate post-intubation practices may lead to long-term detrimental effects in patients. Despite this, these practices are poorly described in the prehospital setting. This study aims to describe the current pre-hospital PISA practices in a private South African emergency medical service. Methodology: Patient report forms (PRF) of intubated patients between 1 Jan 2017 and 31 Dec 2017 from a single private ambulance service were reviewed. Data was analysed descriptively. Correlations were calculated with Spearman's Rank correlations and group differences were calculated with Independent T tests and Mann-Whitney U tests. Significant correlations were entered into a binomial regression model to determine predictive value of receiving PISA. Results: The number of PRFs included for analysis was 437. Of these, 69% of patients received some type of PISA. The estimated time from intubation to 1st PISA ranged from 9 to 12 minutes. There were statistically significantly more PISA interventions in patients who had received Rocuronium (p< 0.01). There was weak but significant correlation between the number of interventions and the mean arterial pressure, (rs = 0.17, p< 0.01) and Glasgow Coma Scale (rs = -0.15, p< 0.01) prior to intubation, along with the transport time to hospital (rs = 0.23, p< 0.01). Conclusion: The PISA practices in the South African pre-hospital setting is comparable to international pre-hospital settings. The time to 1st PISA appears to be shorter in the SA setting. There is an increased number of interventions in the patients who received Rocuronium, which may indicate practitioners being mindful of wakeful paralysis. Practitioners also take the level of consciousness and blood pressure prior to intubation into account when administering PISA. Longer transport times attribute to patients receiving more PISA interventions.

Introduktion: Att skapa fri luftväg i samband med prehospitalt hjärtstopp är en komplicerad åtgärd i en stressande situation. Det finns flera metoder för denna åtgärd och de har olika svårighetsgrad beroende på vilken metod som ambulanssjuksköterskan behöver använda för att nå framgång. Denna åtgärd förväntas ambulanssjuksköterskan klara av trots att miljön är utmanande och tidspressen stor.   Syfte: Att beskriva ambulanssjuksköterskors upplevelser av etablering av fri luftväg i samband med hjärtstopp.   Metod: Kvalitativ intervjustudie som analyseras med latent innehållsanalys. Tolv semistrukturerade intervjuer genomfördes på tre verksamhetsställen i södra Sverige.   Resultat: Ambulanssjuksköterskorna berättade om hur luftvägshantering är en liten men viktig del av allt de ska klara av i sin yrkesroll. Det finns en otrygghet i momentet intubation som beror på bristande utbildning i kombination med hur sällan ambulanssjuksköterskan gör detta i det dagliga arbetet. Studien resulterade i tre huvudkategorier: Otrygghet i yrkesrollen, Prehospitala framgångsfaktorer och Personcentrerad vård genom samarbete med tillhörande tolv subkategorier. Det som bekymrade ambulanssjuksköterskorna mest var luftvägshantering på barn. Det som upplevs vara den största framgångsfaktorn betonades vara de enkla åtgärderna när det gäller luftvägshantering.   Slutsats: För att öka ambulanssjuksköterskans trygghet i luftvägshantering krävs ökade utbildningsinsatser. Arbetsgivaren bör ta ett ökat ansvar för utbildning genom att skapa förutsättningar och uppföljning. Vidare bör de riktlinjer som finns för luftvägshantering ses över. De enklaste metoderna är oftast de bästa prehospitalt. / Introduction: To manage an airway in a prehospital environment is a complex measure in a stressful situation. There are several methods for this measure and they have various level of severity depending on the method the ambulance nurse chooses to apply. This measure is expected to be managed by the ambulance nurse despite rough environment and lack of time.   Purpose: To describe the ambulance nurse’s experiences of airway management in a cardiac arrest situation.   Method:  Twelve semi-structured qualitative interviews was made and analyzed by content analysis. The interviews were made at three different ambulance organizations in the south of Sweden     Result: The ambulance nurses told about how small but essential task airway management is. But it’s still a task they must be able to perform in their work.  There is an insecurity in the moment of intubation which is related to lack of training and how rarely they perform the moment in their daily duties. The study resulted in three main categories: Insecurity in the profession, Prehospital success factors and Person-centered care through teamwork with twelve subcategories. What concerned the ambulance nurses the most was airway management on children. They describe the greatest success factor to be the simplest possible measures when it comes to airway management.   Conclusion: To increase the ambulance nurse’s security in airway management more education efforts is needed. Employers should take a greater responsibility for education by creating conditions and monitoring. Therefore, should the guidelines for airway management be reviewed. The simplest methods in airway management are often the most successful.

A common problem following general anesthesia is postoperative sore throat (POST) and postoperative hoarseness (PH). Symptoms directly correlated with less satisfaction according to the patients. The overall aim of this thesis was to describe patients' postoperative sore throat and hoarseness after general anesthesia with endotracheal intubation or laryngeal mask airway. As well as to investigate the risk factors that are associated with the symptoms, and to test methods that may prevent sore throat and hoarseness after a general anaesthetics. A total of 889 patients are included in the four studies. Incidence of POST varied from 21% up to 52 % depending on endotracheal tube (ETT) size in women (I-IV) and in men was the incidence 32-38% (III-IV). There were no gender difference in POST in study III and IV. The overall incidence of PH varied from 42- 59% (I-IV) in all patients, with no gender differences (III-IV). Following a laryngeal mask airway (LMA) 19% of the patients had POST and 33% of the patients reported PH. Patients with POST do seem to be able to localize their pain in the throat (IV). Different risk factors are shown to contribute to both POST and PH in men and women (II-III). To intubate with a smaller ETT size, 6.0 vs. 7.0 decreased POST in women in the early postoperative period as well as their discomfort from their POST (I). Only 6% of men who needed a laryngeal mask airway had POST compared to 26% of women. The symptoms are more discomforting after an ETT vs. an LMA up to 24 hours (IV). More patients have sore throat and hoarseness in the early postoperative period, but the symptoms can remain up to almost 5 days postoperatively (I, IV). In summary, sore throat and hoarseness following general anesthesia, affects many patients postoperatively. To intubate women with endotracheal size 6.0 decreases both sore throat and hoarseness postoperatively. Women are more likely than men to have a sore throat when a laryngeal mask airway is used.

Bakgrund: I anestesisjuksköterskans ansvar ingår att extubera patienten på ett säkert sätt. I anestesisjuksköterskans arbete fodras ett tvärprofessionellt omhändertagande av patienten inom ett team. Det är ett varierande arbetstempo i en komplex och högteknologisk miljö. Extuberingsprocessen kan medföra många komplikationer som kan ge obehag för patienten som har varit sövd i generell anestesi med endotrachealtub. Extubation ställer därmed höga krav på anestesisjuksköterskan som skall ha fördjupande medicinska och omvårdnadskunskaper vid omhändertagandet av patient. Det saknas forskning kring extubationsprocessen ur en anestesisjuksköterskas perspektiv även om det är ett riskfyllt moment. Syfte: Syftet var att beskriva anestesisjuksköterskors upplevelser och erfarenheter av svårigheter i samband med extubation av patient. Metod: Studien innefattade semistrukturerade intervjuer med nio anestesisjuksköterskor från två sjukhus i Västra Götalandsregionen i Sverige. Datamaterialet analyserades med hjälp av en kvalitativ innehållsanalys. Resultat: Resultatet visade betydande trygghet i att ha utbildning, erfarenhet och kunskap om extubationsprocessen då arbetssättet bygger på erfarenhet. Förmåga att förhålla sig till utmaningar bygger på att anestesisjuksköterskorna upplever en stor respekt för extubationsprocessen eftersom det kan innefatta många risker. Trygghet av att se patientens individuella behov var en betydande faktor för ett komplikationsfritt omhändertagande av patienter. För att främja ett systematiskt och patientsäkert sätt kring patienten, beskrev anestesisjuksköterskorna vikten av utbildning inom extubationsprocessen. Diskussion: I diskussionen jämförs det aktuella resultatet med tidigare forskning. Vidare diskuteras kunskapsbristen och forskning kring fenomenet. Slutsats: Anestesisjuksköterskornas arbete kring extubationsprocessen kräver god kunskap och erfarenhet inom anestesisjukvård. Förmåga till kommunikation och teamarbete är viktiga faktorer för en lyckad extubation.

<p>During mechanical ventilation, patients are connected to the ventilator by an endotracheal tube.

Being a patient in intensive care can be experienced terrifying. Studies have demonstrated the link between unpleasant memories of hospitalization in the ICU and the development of posttraumatic stress disorder, depression, anxiety, and perception of quality of life in its aftermath. Placed on a ventilator, the patient is exposed to multiple invasive procedures. The aim was to describe critical care patients' experience of being intubated or tracheostomated. Method: Literature review using conventional content analysis. Searches were made in the databases Cinahl and Pubmed. Results: The study revealed four main categories: Discomfort, Vulnerability and Communication difficulties that were tied together by category Relief. It turned out that the patients experienced a discomfort caused by the endotracheal tube. Suctioning of airways remembered many of the patients in both discomfort and relief. Being dependent on a ventilator and equipment in order to survive, causing a feeling of vulnerability. Many patients lost hope when they could not communicate, make themselves understood and to be involved in their care. The medical staff has a significant impact on their experiences of intensive care. To find out the reason they were intubated / tracheostomated reduced their fear. This information helped them to bond with reality. The nurse has responsibility to act with compassion and empathy, theory and knowledge to reduce anxiety and facilitate hospital stay for patients.
