INTRODUCTION: Airway management is a critical component of out-of-hospital cardiac arrest (OHCA) resuscitation. The primary aim of this study was to describe pre-hospital airway management in adult patients post-OHCA. Secondary aims were to investigate whether tracheal intubation (TI) versus use of supraglottic airway device (SGA) was associated with patients' outcomes, including ventilator-free days within 26 days of randomization, 6 months neurological outcome and mortality. METHODS: Secondary analysis of the Target Temperature Management-2 (TTM2) trial conducted in 13 countries, including adult patients with OHCA and return of spontaneous circulation, with data available on pre-hospital airway management. A multivariate logistic regression model with backward stepwise selection was employed to assess whether TI versus SGA was associated with outcomes. RESULTS: Of the 1900 TTM2 trial patients, 1702 patients (89.5%) were included, with a mean age of 64 years (Standard Deviation, SD = 13.53); 79.1% were males. Pre-hospital airway management was SGA in 484 (28.4%), and TI in 1218 (71.6%) patients. At hospital admission, 87.8% of patients with SGA and 98.5% with TI were mechanically ventilated (p < 0.001). In the multivariate analysis, TI in comparison with SGA was not independently associated with an increase in ventilator-free days within 26 days of randomization, improved neurological outcomes, or decreased mortality. The hazard ratio for mortality with TI vs. SGA was 1.06, 95%Confidence Interval (CI) 0.88-1.28, p = 0.54. CONCLUSIONS: In the multicentre randomized TTM2-trial including patients with OHCA, most patients received prehospital endotracheal intubation to manage their airway. The choice of pre-hospital airway device was not independently associated with patient clinical outcomes. TRIAL REGISTRATION NUMBER: NCT02908308.

BACKGROUND: The i-gel® Plus is a modified version of the i-gel® supraglottic airway device. It contains a wider drainage port; a longer tip; ramps inside the breathing channel; and an additional port for oxygen delivery. There has been no prospective evaluation of this device in clinical practice. METHODS: This international, multicentre, prospective cohort study aimed to evaluate the performance of the i-gel Plus in adult patients undergoing elective procedures under general anaesthesia. The primary outcome was overall insertion success rate, defined as the ability to provide effective airway management through the device from insertion until the end of the surgical procedure. Secondary outcomes included device performance and incidence of postoperative adverse events. Data from the first 1000 patients are reported. RESULTS: In total, 1012 patients were enrolled; 12 forms were excluded from the final analysis due to incomplete data leaving 1000 included patients (545 female). Overall insertion success rate was 98.6%, with a first-attempt success rate of insertion of 88.2%. A significant difference between females and males was seen for the overall success rate (97.4% vs. 99.6% respectively) but not for first-attempt successful insertion. Mean (SD) oropharyngeal seal pressure was 32 (7) cmH2O. The only independent factor that increased the risk of first-attempt failure was low operator experience. Complications included desaturation < 85% in 0.6%; traces of blood on the device in 7.4%; laryngospasm in 0.5%; and gastric contents inside the bowl in 0.2% of patients. CONCLUSIONS: The i-gel Plus appears to be an effective supraglottic airway device that is associated with a high insertion success rate and a reasonably low incidence of complications.

OBJECTIVES: Airway management during cardiopulmonary resuscitation is particularly important for patients with out-of-hospital cardiac arrest (OHCA). This study was performed to compare the efficacy of the most commonly used out-of-hospital airway management methods in increasing the survival to discharge in patients with OHCA. METHODS: We screened all relevant literature from database inception to 21st January 2019 in PubMed, Web of Science, Embase, and the Cochrane Library. We included all randomized controlled trials (RCTs) of airway management for OHCA in adults (≥16 years of age) with no limitations on publication status, publication date, or language. The primary outcome was survival to discharge. The secondary outcomes were the overall airway technique success rate, return of spontaneous circulation, and survival to hospital admission. RESULTS: Overall, from 1986 to 2018, 9 RCTs involving 13,949 patients were included in the network meta-analysis, and the efficacy of six airway management methods for patients with OHCA were compared. However, none of the results were statistically significant. CONCLUSIONS: As the gold standard of airway management for patients with out-of-hospital cardiac arrest in most countries, endotracheal intubation (ETI) has been widely used for many years. However, our systematic review and network meta-analysis showed that ETI is no better than other methods in increasing the survival to discharge. This is not directly proportional to the various preparations required before ETI. Additional randomized controlled trials are needed to identify more effective methods and improve patients' outcome.

INTRODUCTION: Supraglottic airway devices represent a less invasive method of airway management than tracheal intubation during general anaesthesia. Their continued development is focused mainly on improvements in the insertion success rate and minimalisation of perioperative and postoperative complications. The i-gel Plus is a novel, anatomically preshaped supraglottic airway device which achieves a perilaryngeal seal due to a non-inflatable cuff made of a soft thermoplastic elastomer. The purpose of this cohort study is to assess the success rate of the i-gel Plus use during elective procedures under general anaesthesia, its intraoperative performance, and the degree of postoperative complications. METHODS AND ANALYSIS: This is a multicentre, prospective, interventional cohort study. The enrolment will take place in seven centres in four European countries. We plan to enrol 2000 adult patients in total, who are scheduled for elective surgery under general anaesthesia, and with an indication for use of a supraglottic airway device for management of their airway. The study is projected to run over a period of 18 months. The primary outcome of the study is the total success rate of the i-gel Plus insertion in terms of successful ventilation and oxygenation through the device. Secondary outcomes include perioperative parameters, such as insertion time, seal/leak pressures, number of insertion attempts and postoperative adverse events and complications. Postoperative follow-up will be performed at 1 hour, 24 hours in all patients, and for selected patients at 3 and 6 months. ETHICS AND DISSEMINATION: The cohort study has received the following ethical approvals: General University Hospital Prague, University Hospital Olomouc, University Military Hospital Prague, University Hospital Barcelona, University Hospital Lodz, Antrim Area Hospital, Craigavon Area Hospital, Office for Research Ethics Committees Northern Ireland. The results will be published in peer-reviewed journals and presented at relevant anaesthesia conferences. TRIAL REGISTRATION NUMBER: ISRCTN86233693;Pre-results.

Adekvátní zajištění oxygenace a průchodných dýchacích cest je jedním z klíčových faktorů pro přežití pacienta v přednemocniční péči. Hlavním rozdílem proti operačnímu sálu je prostředí zásahu a zkušenost i kvalifikace zdravotníka. Základní techniky zahrnují použití manuálních manévrů ke zprůchodnění dýchacích cest, ventilaci obličejovou maskou i zavedení ústních nebo nosních vzduchovodů. K pokročilým technikám patří zavedení supraglotické pomůcky a tracheální intubace. U malého množství pacientů a ve válečné medicíně je nutné použít chirurgickou techniku zajištění dýchacích cest, koniotomii. Tracheální intubace stále zůstává metodou volby v rukou zkušeného zdravotníka pro stavy se závažnou poruchou vědomí a pro resuscitaci při zástavě oběhu. Pro zvýšení úspěšnosti tracheální intubace v terénu jsou používány další pomůcky, bužie nebo videolaryngoskopy. Supraglotické pomůcky zaváděné v přednemocniční péči zahrnují laryngeální masky, i gel a laryngeální tubus.
Adequate oxygenation and maintaining the patent airway are one of the key factors for patient survival in prehospital care. The main difference against the operating room is the environment of the accident and experience with the qualification of the provider. Basic techniques include the use of manual maneuvers for opening the airway, bag-mask ventilation, and insertion of the oropharyngeal or nasopharyngeal airways. Advanced techniques involve the insertion of a supraglottic airway device and tracheal intubation. Surgical cricothyrotomy is indicated only in a small number of patients and in the battlefield medicine. Tracheal intubation still remains a method of choice when performed by experience provider, for the unconscious victims and resuscitation in out-of-hospital cardiac arrest. Special tools such as gum elastic bougie or videolaryngoscopes are employed to increase the success rate of out of hospital tracheal intubation. Supraglottic airway devices inserted in prehospital care include laryngeal mask airways, i-gel, and laryngeal tube.
