Applicazione delle nuove linee guida AARC per l'aspirazione endotracheale : impatto sui parametri vitali in pazienti sottoposti a rivascolarizzazione miocardica (BPAC)

RIASSUNTOIntroduzione : La manovra di bronco aspirazione è una procedura che espone il paziente critico a modificazioni dei parametri vitali. Le nuove linee guida AARC hanno enfatizzato sia l'importanza dell'identificazione corretta del momento in cui eseguire la procedura, sia l'utilizzo routinario del sistema chiuso. Obiettivo : Applicare le nuove linee guida AARC utilizzando un rilevatore sonoro per l'identificazione della presenza di secrezioni (TBA care©) e l'aspirazione a circuito chiuso ed analizzare l'andamento dei parametri vitali in una popolazione di pazienti cardiochirurgici. Materiali e metrodi: Lo studio è di tipo osservazionale. Sono stati investigati 15 pazienti sottoposti a BPAC, ricoverati in terapia intensiva cardiochirurgia. Sono stati registrati in continuo i seguenti parametri vitali HR, PAS, PAS*HR, ST varie derivazioni, SpO2, PEEP, RRv, TVc in quattro finestre temporali, 5 minuti prima della manovra di Broncoaspirazione, al momento della manovra (momento 0), a 5 minuti dalla stessa e 10 minuti dopo. Risultati : I parametri vitali rimangono sostanzialmente stabili nei quattro step investigati, con minime variazioni (Variazione percentuale durante la manovra rispetto al basale : HR +2,93%, PAS + 5,66%, SpO2 – 0,13%) . Non si sono registrate modificazioni del tratto ST. Si registra un aumento dell'indice di lavoro cardiaco, che però rientra a 5 minuti dall'esecuzione della manovra. Non si sono verificate desaturazioni arteriose. Conclusioni : Le alterazioni dei parametri vitali osservate, seppur minime, suggeriscono di mantenere il massimo monitoraggio emodinamico e respiratorio. Nella popolazione osservata, l'utilizzo di tecnologie per la diagnosi associate al sistema chiuso di broncoaspirazione ha evitato l'insorgenza di complicanze legate alla manovra.Parole chiave: aspirazione endotracheale, identificazione delle secrezioni, sistema chiuso, ventilazione meccanica, gestione delle secrezioniABSTRACT Introduction: Endotracheal suctioning is a procedure that exposes the patient to critical changes in vital signs. New AARC guidelines have emphasized both the importance of correct identification when to perform the procedure, and the routine use of closed system. Objective: To implement the new guidelines AARC using a sound detector for identifying the presence of secretions (TBA care ©) , closed suctioning circuit and analyze the performance of vital signs in a population of cardiac patients. Methods : The study is observational. Were investigated 15 patients undergoing CABG, cardiac surgery ICU. Were continuously recorded the following vital signs HR, SBP, SBP * HR, ST various leads, SpO2, PEEP, RRV, TVC in four time windows, 5 minutes before the suctioning maneuver at the time of operation (time 0), 5 minutes from the same and 10 minutes later. Results: Vital signs remain stable in the four steps investigated, with minor variations (percent change from baseline during the maneuver: HR +2.93% 5.66% PAS +, SpO2 - 0.13%). There were no ST segment changes. There is an increase in the cardiac work, but within 5 minutes from the execution of the maneuver. There were no arterial desaturation. Conclusions: The observed changes in vital signs, albeit small, suggest to keep the maximum hemodynamic and respiratory monitoring. The use of technologies for the diagnosis associated with the closed system of broncoaspiration has prevented the onset of complications related to the maneuver.Keywords: endotracheal suctioning, secretion detector, closed system, mechanical ventilation, secretion managemen

Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI

Search for stop and higgsino production using diphoton Higgs boson decays

Results are presented of a search for a "natural" supersymmetry scenario with gauge mediated symmetry breaking. It is assumed that only the supersymmetric partners of the top-quark (stop) and the Higgs boson (higgsino) are accessible. Events are examined in which there are two photons forming a Higgs boson candidate, and at least two b-quark jets. In 19.7 inverse femtobarns of proton-proton collision data at sqrt(s) = 8 TeV, recorded in the CMS experiment, no evidence of a signal is found and lower limits at the 95% confidence level are set, excluding the stop mass below 360 to 410 GeV, depending on the higgsino mass

Severe early onset preeclampsia: short and long term clinical, psychosocial and biochemical aspects

Preeclampsia is a pregnancy specific disorder commonly defined as de novo hypertension and proteinuria after 20 weeks gestational age. It occurs in approximately 3-5% of pregnancies and it is still a major cause of both foetal and maternal morbidity and mortality worldwide1. As extensive research has not yet elucidated the aetiology of preeclampsia, there are no rational preventive or therapeutic interventions available. The only rational treatment is delivery, which benefits the mother but is not in the interest of the foetus, if remote from term. Early onset preeclampsia (<32 weeks’ gestational age) occurs in less than 1% of pregnancies. It is, however often associated with maternal morbidity as the risk of progression to severe maternal disease is inversely related with gestational age at onset2. Resulting prematurity is therefore the main cause of neonatal mortality and morbidity in patients with severe preeclampsia3. Although the discussion is ongoing, perinatal survival is suggested to be increased in patients with preterm preeclampsia by expectant, non-interventional management. This temporising treatment option to lengthen pregnancy includes the use of antihypertensive medication to control hypertension, magnesium sulphate to prevent eclampsia and corticosteroids to enhance foetal lung maturity4. With optimal maternal haemodynamic status and reassuring foetal condition this results on average in an extension of 2 weeks. Prolongation of these pregnancies is a great challenge for clinicians to balance between potential maternal risks on one the eve hand and possible foetal benefits on the other. Clinical controversies regarding prolongation of preterm preeclamptic pregnancies still exist – also taking into account that preeclampsia is the leading cause of maternal mortality in the Netherlands5 - a debate which is even more pronounced in very preterm pregnancies with questionable foetal viability6-9. Do maternal risks of prolongation of these very early pregnancies outweigh the chances of neonatal survival? Counselling of women with very early onset preeclampsia not only comprises of knowledge of the outcome of those particular pregnancies, but also knowledge of outcomes of future pregnancies of these women is of major clinical importance. This thesis opens with a review of the literature on identifiable risk factors of preeclampsia
