Intubación con mascarilla laríngea Total Video Track en pacientes súper obesos - serie de casos. Total Track video intubating laryngeal mask in super-obese patients - series of cases. Gaszynski T. Ther Clin Risk Manag. 2016 Mar 2;12:335-8. doi: 10.2147/TCRM.S95695. eCollection 2016. Abstract BACKGROUND: Super-obese patients are at increased risk of difficult mask ventilation and difficult intubation. Therefore, devices that allow for simultaneous ventilation/oxygenation during attempts to visualize the entrance to the larynx, increase patient safety. TotalTrack video intubatinglaryngeal mask is a new device that allows for ventilation during intubation efforts. PATIENTS AND METHODS: Twenty-four super-obese patients (body mass index >50 kg/m(2)) were divided into two subgroups: intubation efforts using 1) TotalTrack and 2) Macintosh blade standard laryngoscope in induction of general anesthesia. Visualization and successful intubation was evaluated for both groups with ventilation and post-mask complications additionally evaluated for TotalTrack. RESULTS: In all cases in the TotalTrack group, the Cormack-Lehane score was 1, ventilation and intubation was successful in 11/12 patients. No hypoxia during intubation efforts was recorded. No serious complications of use of TotalTrack were observed. In the Macintosh blade laryngoscope group, all patients were intubated, but the Cormack-Lehane score was 2 in four cases, and 3 in three cases. CONCLUSION: TotalTrack video intubating laryngeal mask is a device that allows for better visualization of the larynx compared to the standard Macintosh blade laryngoscope, it provides effective ventilation/oxygenation and intubation in super-obese patients.

Prior to the commencement of this study, there was no published literature on the performance of the TotalTrack®. Methods: The device was evaluated in sixty patients without predictors for difficult airway under general anaesthesia with neuromuscular blockade. Primary outcomes were laryngeal mask seal pressures and success of tracheal intubation through the device. Results: Insertion and ventilation was successful in 98.3% of cases. Median static leak and maximal inflation pressures of the laryngeal mask component were 32 and 40 cmH2O respectively. Tracheal intubation through the device was successful in 95% of cases, with a mean intubation time of 9.5 s. No gastric insufflation occurred. Haemodynamic variability was found to be clinically insignificant. No significant side-effects were reported. Conclusions: In this initial study, the TotalTrack® VLM was found to be effective as a laryngeal mask airway, exhibiting good sealing pressures. It facilitated predictable, easy intubating conditions under video guidance, with minimal interruption of ventilation.

Transfusión sanguínea / Blood transfusion

Mayo 2, 2016. No. 2314

Impacto de la edad de la sangre de banco sobre la mortalidad del traumatizado. Revisión sistemática Impact of the age of stored blood on trauma patient mortality: a systematic review. Sowers N1, Froese PC1, Erdogan M1, Green RS1. Can J Surg. 2015 Oct;58(5):335-42. Abstract BACKGROUND: The impact of the age of stored red blood cells on mortality in patients sustaining traumatic injuries requiring transfusion of bloodproducts is unknown. The objective of this systematic review was to identify and describe the available literature on the use of older versus newerblood in trauma patient populations. METHODS: We searched PubMed, Embase, Lilac and the Cochrane Database for published studies comparing the transfusion of newer versus older red blood cells in adult patients sustaining traumatic injuries. Studies included for review reported on trauma patients receiving transfusions of packed red blood cells, identified the age of stored blood that was transfused and reported patient mortality as an end point. We extracted data using a standardized form and assessed study quality using the Newcastle-Ottawa Scale. RESULTS: Seven studies were identified (6780 patients) from 3936 initial search results. Four studies reported that transfusion of older blood was independently associated with increased mortality in trauma patients, while 3 studies did not observe any increase in patient mortality with the use of older versus newer blood. Three studies associated the transfusion of older blood with adverse patient outcomes, including longer stay in the intensive care unit, complicated sepsis, pneumonia and renal dysfunction. Studies varied considerably in design, volumes of blood transfused and definitions applied for old and new blood. CONCLUSION: The impact of the age of stored packed red blood cells on mortality in trauma patients is inconclusive. Future investigations are warranted. PDF   Transfusión perioperatoria de sangre. Lo que no conocemos Perioperative Red Blood Cell Transfusion: What We Do Not Know. Lei C, Xiong LZ1. Chin Med J (Engl). 2015 Sep 5;128(17):2383-6. doi: 10.4103/0366-6999.163384. Abstract OBJECTIVE: Blood transfusion saves lives but may also increase the risk of injury. The objective of this review was to evaluate the possible adverse effects related to transfusion of red blood cell (RBC) concentrates stored for prolonged periods. DATA SOURCES: The data used in this review were mainly from PubMed articles published in English up to February 2015. STUDY SELECTION: Clinical and basic research articles were selected according to their relevance to this topic. RESULTS: The ex vivo changes to RBC that occur during storage are collectively called storage lesion. It is still inconclusive if transfusion of RBC with storage lesion has clinical relevance. Multiple ongoing prospective randomized controlled trials are aimed to clarify this clinical issue. It was observed that the adverse events related to stored RBC transfusion were prominent in certain patient populations, including trauma, critical care, pediatric, and cardiac surgery patients, which leads to the investigation of underlying mechanisms. It is demonstrated that free hemoglobin toxicity, decreasing of nitric oxide bioavailability, and free iron-induced increasing of inflammation may play an important role in this process. CONCLUSION: It is still unclear whether transfusion of older RBC has adverse effects, and if so, which factors determine such clinical effects. However, considering the magnitude of transfusion and the widespread medical significance, potential preventive strategies should be considered, especially for the susceptible recipients.

Sepsis

Diseño de ensayos fase 3 en sepsis: aplicación de las experiencias adquiridas a partir de ensayos de cuidados críticos en la insuficiencia cardíaca aguda. Designing phase 3 sepsis trials: application of learned experiences from critical care trials in acute heart failure. Mebazaa A1, Laterre PF2, Russell JA3, Bergmann A4, Gattinoni L5, Gayat E6, Harhay MO7, Hartmann O4, Hein F4, Kjolbye AL8, Legrand M9, Lewis RJ10,Marshall JC11, Marx G12, Radermacher P13, Schroedter M4, Scigalla P4, Stough WG14, Struck J4, Van den Berghe G15, Yilmaz MB16, Angus DC17. J Intensive Care. 2016 Mar 31;4:24. doi: 10.1186/s40560-016-0151-6. eCollection 2016. Abstract Substantial attention and resources have been directed to improving outcomes of patients with critical illnesses, in particular sepsis, but all recent clinical trials testing various interventions or strategies have failed to detect a robust benefit on mortality. Acute heart failure is also a critical illness, and although the underlying etiologies differ, acute heart failure and sepsis are critical care illnesses that have a high mortality in which clinical trials have been difficult to conduct and have not yielded effective treatments. Both conditions represent a syndrome that is often difficult to define with a wide variation in patient characteristics, presentation, and standard management across institutions. Referring to past experiences and lessons learned in acute heart failure may be informative and help frame research in the area of sepsis. Academic heart failure investigators and industry have worked closely with regulators for many years to transition acute heart failure trials away from relying on dyspnea assessments and all-cause mortality as the primary measures of efficacy, and recent trials have been designed to assess novel clinical composite endpoints assessing organ dysfunction and mortality while still assessing all-cause mortality as a separate measure of safety. Applying the lessons learned in acute heart failure trials to severe sepsis and septic shock trials might be useful to advance the field. Novel endpoints beyond all-cause mortality should be considered for future sepsis trials.
