Percutaneous tracheostomy: Comparison of three different methods with respect to tracheal cartilage injury in cadavers-Randomized controlled study.

Background: Performing tracheostomy improves patient comfort and success rate of weaning from prolonged invasive mechanical ventilation. Data suggest that patients have more benefit of percutaneous technique than the surgical procedure, however, there is no consensus on the percutaneous method of choice regarding severe complications such as late tracheal stenosis. Aim of this study was comparing incidences of cartilage injury caused by different percutaneous dilatation techniques (PDT), including Single Dilator, Griggs' and modified (bidirectional) Griggs' method. Materials and methods: Randomized observational study was conducted on 150 cadavers underwent post-mortem percutaneous tracheostomy. Data of cadavers including age, gender and time elapsed from death until the intervention (more or less than 72 h) were collected and recorded. Primary and secondary outcomes were: rate of cartilage injury and cannula malposition respectively. Results: Statistical analysis revealed that method of intervention was significantly associated with occurrence of cartilage injury, as comparing either standard Griggs' with Single Dilator (p = 0.002; OR: 4.903; 95% CI: 1.834-13.105) or modified Griggs' with Single Dilator (p < 0.001; OR: 6.559; 95% CI: 2.472-17.404), however, no statistical difference was observed between standard and modified Griggs' techniques (p = 0.583; OR: 0.748; 95% CI: 0.347-1.610). We found no statistical difference in the occurrence of cartilage injury between the early- and late post-mortem group (p = 0.630). Neither gender (p = 0.913), nor age (p = 0.529) influenced the rate of cartilage fracture. There was no statistical difference between the applied PDT techniques regarding the cannula misplacement/malposition. Conclusion: In this cadaver study both standard and modified Griggs' forceps dilatational methods were safer than Single dilator in respect of cartilage injury.

[Role of anthropometric parameters in percutaneous tracheostomies performed on cadavers]. / Az antropometriai paraméterek szerepe a cadaveren végzett percutan tracheostomás módszerekben.

INTRODUCTION AND OBJECTIVE: For patients requiring prolonged mechanical ventilation, tracheostomy becomes necessary, which may be performed through surgical or percutaneous methods. In this study, we used three different methods of percutaneous dilatational tracheostomy. Our goal was to identify anthropometric parameters relevant for the correct position of the tracheostomy tube. MATERIAL AND METHODS: Randomized, controlled observational study was performed on 118 cadavers. Three different tracheostomy methods were used: the Griggs (n = 37), the Griggs modified by Élo (n = 45), and the Ciaglia's Blue Rhino (n = 36). The neck circumference, jugulomental distance, and mid-upper arm circumference were measured on each cadaver. We assessed whether the aforementioned parameters related with the appropriate positioning of the tracheostomy tube Results: Significant correlation was found (p = 0.0287) between mid-upper arm circumference and incorrect tracheostomy tube position (below the fourth tracheal cartilage ring). We identified the value of 30 cm of mid-upper arm circumference as the ideal cut-off for predicting tube malposition (sensitivity: 63.63%, specificity: 60.22%). CONCLUSION: When planning percutaneous tracheostomy, it is important to measure the anthropometric parameters. If mid-upper arm circumference is 30 cm or higher we recommend other tests and/or ENT (ear, nose, and throat) consultation. Orv Hetil. 2023; 164(16): 630-635.

Global Comparison of Communication of End-of-Life Decisions in the ICU.

BACKGROUND: Prolonging life in the ICU increasingly is possible, so decisions to limit life-sustaining therapies frequently are made and communicated to patients and families or surrogates. Little is known about worldwide communication practices and influencing factors. RESEARCH QUESTION: Are there regional differences in end-of-life communication practices in ICUs worldwide? STUDY DESIGN AND METHODS: This analysis of data from a prospective, international study specifically addressed end-of-life communications in consecutive patients who died or had limitation of life-sustaining therapy over 6 months in 199 ICUs in 36 countries, grouped regionally. End-of-life decisions were recorded for each patient and ethical practice was assessed retrospectively for each ICU using a 12-point questionnaire developed previously. RESULTS: Of 87,951 patients admitted, 12,850 died or experienced a limitation of therapy (14.6%). Of these, 1,199 patients (9.3%) were known to have an advance directive, and wishes were elicited from 6,456 patients (50.2%). Limitations of life-sustaining therapy were implemented for 10,401 patients (80.9%), 1,970 (19.1%) of whom had mental capacity at the time, and were discussed with 1,507 patients (14.5%) and 8,461 families (81.3%). Where no discussions with patients occurred (n = 8,710), this primarily was because of a lack of mental capacity in 8,114 patients (93.2%), and where none occurred with families (n = 1,622), this primarily was because of unavailability (n = 720 [44.4%]). Regional variation was noted for all end points. In generalized estimating equation (GEE) analyses, the odds for discussions with the patient or family increased by 30% (OR, 1.30; 95% CI, 1.18-1.44; P < .001) for every one-point increase in the Ethical Practice Score and by 92% (OR, 1.92; 95% CI, 1.28-2.89; P = .002) in the presence of an advance directive. INTERPRETATION: End-of-life communication with patients and families or surrogates varies markedly in different global regions. GEE analysis supports the hypothesis that communication may increase with ethical practice and an advance directive. Greater effort is needed to align treatment with patients' wishes.

Role of faith in strategies of healthcare professionals in intensive care units in end-of-life decision making / A vallásosság szerepe az intenzív osztályon dolgozó orvosok és ápolók véleményének kialakításában az életvégi döntések meghozatalakor.

Összefoglaló. Bevezetés: A haldoklást minden korban kulturális és vallási szabályok vették körül, melyek a mai napig hatnak a társadalomban. A 21. században számos beteg a kórházban, az intenzív osztályon fejezi be életét, ahol nem ritkán kerülhet sor életvégi döntés meghozatalára. Célkituzés: Vizsgálatunk célja annak feltárása volt, milyen hatással van az orvosok és ápolók vallásossága a kezeléskorlátozással kapcsolatos döntésekre az intenzív osztályon. Módszer: Magyarországi intenzív osztályokon dolgozó orvosok és szakdolgozók körében végeztünk kérdoíves felmérést a vallás életvégi döntésekre gyakorolt hatásáról. 189 orvos és 105 ápoló által anonim módon kitöltött kérdoívet elemeztünk. Eredmények: Az intenzív osztályra történo betegfelvételre nem volt hatással a vallásosság, azonban a szabad ágyak száma a vallásos orvosokat erosebben befolyásolta, mint az ateista és választ nem adó orvosokat (<0,0001). A vallásukat gyakorló orvosok szignifikánsan jobban figyelembe vették a hozzátartozó kérését, mint az ateisták (p = 0,0002). A vallásos ápolók gyakrabban folytatnák a beteg kezelését a hozzátartozó kérése ellenére is, ha még látnának esélyt a gyógyulásra, mint a nem vallásosak. Következtetés: Vizsgálatunk alátámasztotta, hogy a világnézet befolyásolja az orvosokat és ápolókat az élet végérol hozott döntésekben. A kezeléskorlátozásról hozott döntés összetett, elengedhetetlen megismerni hozzá a beteg és családjának haldoklással kapcsolatos vallási szokásait, mivel jó életvégi döntés a világnézeti szempontok figyelembevétele nélkül nem hozható. Orv Hetil. 2021; 162(51): 2047-2054. INTRODUCTION: Death has always been surrounded by habits in all ages, influenced by cultural and religious differences. Many patients finish their lives at intensive care units where end-of-life decisions are the part of everyday practice in the 21th century. OBJECTIVE: The goal of our study was to assess how the religious beliefs of physicians and nurses affect their decision on therapy restriction. METHOD: We have performed questionnaire-based enquiries among physicians and nurses working at intensive care units on how religion affects end-of-life decisions. We have analyzed the anonymous questionnaires filled out by 189 physicians and 105 nurses. RESULTS: Our results have confirmed the hypothesis that religion affects decision making about therapy restriction. Patients' admissions were not affected by religious beliefs, but the number of available patient beds influenced the religious physicians more than the atheists ones or the non-responders (<0.0001). Actively religious physicians complied significantly better with the relatives than atheists (p = 0.0002). Religious nurses would continue patient treatment even against the will of relatives more often than atheists if they see a chance for recovery. CONCLUSION: The study supports that religion influences physicians and nurses in their end-of-life decisions. Decisions on therapy restriction are complex; it is important to find out religious beliefs and perception of death among patients and families because good end-of-life decision cannot be made disregarding religious considerations.

Impact of perceived inappropiate cardiopulmonary resuscitation on emergency clinicians' intention to leave the job: Results from a cross-sectional survey in 288 centres across 24 countries.

INTRODUCTION: Cardiopulmonary resuscitation (CPR) in patients with a poor prognosis increases the risk of perception of inappropriate care leading to moral distress in clinicians. We evaluated whether perception of inappropriate CPR is associated with intention to leave the job among emergency clinicians. METHODS: A cross-sectional multi-centre survey was conducted in 24 countries. Factors associated with intention to leave the job were analysed by conditional logistic regression models. Results are expressed as odds ratios with 95% confidence intervals. RESULTS: Of 5099 surveyed emergency clinicians, 1836 (36.0%) were physicians, 1313 (25.7%) nurses, 1950 (38.2%) emergency medical technicians. Intention to leave the job was expressed by 1721 (33.8%) clinicians, 3403 (66.7%) often wondered about the appropriateness of a resuscitation attempt, 2955 (58.0%) reported moral distress caused by inappropriate CPR. After adjustment for other covariates, the risk of intention to leave the job was higher in clinicians often wondering about the appropriateness of a resuscitation attempt (1.43 [1.23-1.67]), experiencing associated moral distress (1.44 [1.24-1.66]) and who were between 30-44 years old (1.53 [1.21-1.92] compared to <30 years). The risk was lower when the clinician felt valued by the team (0.53 [0.42-0.66]), when the team leader acknowledged the efforts delivered by the team (0.61 [0.49-0.75]) and in teams that took time for debriefing (0.70 [0.60-0.80]). CONCLUSION: Resuscitation attempts perceived as inappropriate by clinicians, and the accompanying moral distress, were associated with an increased likelihood of intention to leave the job. Interprofessional collaboration, teamwork, and regular interdisciplinary debriefing were associated with a lower risk of intention to leave the job. ClinicalTrials.gov; No.: NCT02356029.

Cardiopulmonary Resuscitation in Adults Over 80: Outcome and the Perception of Appropriateness by Clinicians.

OBJECTIVES: To determine the prevalence of clinician perception of inappropriate cardiopulmonary resuscitation (CPR) regarding the last out-of-hospital cardiac arrest (OHCA) encountered in an adult 80 years or older and its relationship to patient outcome. DESIGN: Subanalysis of an international multicenter cross-sectional survey (REAPPROPRIATE). SETTING: Out-of-hospital CPR attempts registered in Europe, Israel, Japan, and the United States in adults 80 years or older. PARTICIPANTS: A total of 611 clinicians of whom 176 (28.8%) were doctors, 123 (20.1%) were nurses, and 312 (51.1%) were emergency medical technicians/paramedics. RESULTS AND MEASUREMENTS: The last CPR attempt among patients 80 years or older was perceived as appropriate by 320 (52.4%) of the clinicians; 178 (29.1%) were uncertain about the appropriateness, and 113 (18.5%) perceived the CPR attempt as inappropriate. The survival to hospital discharge for the "appropriate" subgroup was 8 of 265 (3.0%), 1 of 164 (.6%) in the "uncertain" subgroup, and 2 of 107 (1.9%) in the "inappropriate" subgroup (P = .23); 503 of 564 (89.2%) CPR attempts involved non-shockable rhythms. CPR attempts in nursing homes accounted for 124 of 590 (21.0%) of the patients and were perceived as appropriate by 44 (35.5%) of the clinicians; 45 (36.3%) were uncertain about the appropriateness; and 35 (28.2%) perceived the CPR attempt as inappropriate. The survival to hospital discharge for the nursing home patients was 0 of 107 (0%); 104 of 111 (93.7%) CPR attempts involved non-shockable rhythms. Overall, 36 of 543 (6.6%) CPR attempts were undertaken despite a known written do not attempt resuscitation decision; 14 of 36 (38.9%) clinicians considered this appropriate, 9 of 36 (25.0%) were uncertain about its appropriateness, and 13 of 36 (36.1%) considered this inappropriate. CONCLUSION: Our findings show that despite generally poor outcomes for older patients undergoing CPR, many emergency clinicians do not consider these attempts at resuscitation to be inappropriate. A professional and societal debate is urgently needed to ensure that first we do not harm older patients by futile CPR attempts. J Am Geriatr Soc 68:39-45, 2019.

Prevalence of Disagreement About Appropriateness of Treatment Between ICU Patients/Surrogates and Clinicians.

BACKGROUND: ICU patients/surrogates may experience adverse outcomes related to perceived inappropriate treatment. The objective was to determine the prevalence of patient/surrogate-reported perceived inappropriate treatment, its impact on adverse outcomes, and discordance with clinicians. METHODS: We conducted a multicenter, prospective, observational study of adult ICU patients. RESULTS: For 151 patients, 1,332 patient, surrogate, nurse, and physician surveys were collected. Disagreement between patients/surrogates and clinicians regarding "too much" treatment being administered occurred in 26% of patients. Disagreement regarding "too little" treatment occurred in 10% of patients. Disagreement about perceived inappropriate treatment was associated with prognostic discordance (P = .02) and lower patient/surrogate satisfaction (Likert scale 1-5 of 4 vs 5; P = .02). Patient/surrogate respondents reported "too much" treatment in 8% of patients and "too little" treatment in 6% of patients. Perceived inappropriate treatment was associated with moderate or high respondent distress for 55% of patient/surrogate respondents and 35% of physician/nurse respondents (P = .30). Patient/surrogate perception of inappropriate treatment was associated with lower satisfaction (Family Satisfaction in the ICU Questionnaire-24, 69.9 vs 86.6; P = .002) and lower trust in the clinical team (Likert scale 1-5 of 4 vs 5; P = .007), but no statistically significant differences in depression (Patient Health Questionnaire-2 of 2 vs 1; P = .06) or anxiety (Generalized Anxiety Disorder-7 Scale of 7 vs 4; P = .18). CONCLUSIONS: For approximately one-third of ICU patients, there is disagreement between clinicians and patients/surrogates about the appropriateness of treatment. Disagreement about appropriateness of treatment was associated with prognostic discordance and lower patient/surrogate satisfaction. Patients/surrogates who reported inappropriate treatment also reported lower satisfaction and trust in the ICU team.

Perception of inappropriate cardiopulmonary resuscitation by clinicians working in emergency departments and ambulance services: The REAPPROPRIATE international, multi-centre, cross sectional survey.

INTRODUCTION: Cardiopulmonary resuscitation (CPR) is often started irrespective of comorbidity or cause of arrest. We aimed to determine the prevalence of perception of inappropriate CPR of the last cardiac arrest encountered by clinicians working in emergency departments and out-of-hospital, factors associated with perception, and its relation to patient outcome. METHODS: A cross-sectional survey was conducted in 288 centres in 24 countries. Factors associated with perception of CPR and outcome were analyzed by Cochran-Mantel-Haenszel tests and conditional logistic models. RESULTS: Of the 4018 participating clinicians, 3150 (78.4%) perceived their last CPR attempt as appropriate, 548 (13.6%) were uncertain about its appropriateness and 320 (8.0%) perceived inappropriateness; survival to hospital discharge was 370/2412 (15.3%), 8/481 (1.7%) and 8/294 (2.7%) respectively. After adjusting for country, team and clinician's characteristics, the prevalence of perception of inappropriate CPR was higher for a non-shockable initial rhythm (OR 3.76 [2.13-6.64]; P < .0001), a non-witnessed arrest (2.68 [1.89-3.79]; P < .0001), in older patients (2.94 [2.18-3.96]; P < .0001, for patients >79 years) and in case of a "poor" first physical impression of the patient (3.45 [2.36-5.05]; P < .0001). In accordance, non-shockable and non-witnessed arrests were both associated with lower survival to hospital discharge (0.33 [0.26-0.41]; P < 0.0001 and 0.25 [0.15-0.41]; P < 0.0001, respectively), as were older patient age (0.25 [0.14-0.44]; P < 0.0001 for patients >79 years) and a "poor" first physical impression (0.26 [0.19-0.35]; P < 0.0001). CONCLUSIONS: The perception of inappropriate CPR increased when objective indicators of poor prognosis were present and was associated with a low survival to hospital discharge. Factoring clinical judgment into the decision to (not) attempt CPR may reduce harm inflicted by excessive resuscitation attempts.

Prevention of tracheal cartilage injury with modified Griggs technique during percutaneous tracheostomy - Randomized controlled cadaver study.

INTRODUCTION: Tracheal stenosis is the most common severe late complication of percutaneous tracheostomy causing significant decrease in quality of life. Applying modified Griggs technique reduced the number of late tracheal stenoses observed in our clinical study. The aim of this study was to investigate the mechanism of this relationship. MATERIALS AND METHODS: Forty-six cadavers were randomized into two groups according to the mode of intervention during 2006-2008. Traditional versus modified Griggs technique was applied in the two groups consequently. Wider incision, surgical preparation, and bidirectional forceps dilation of tracheal wall were applied in modified technique. Injured cartilages were inspected by sight and touch consequently. Age, gender, level of intervention, and number of injured tracheal cartilages were registered. RESULTS: Significantly less frequent tracheal cartilage injury was observed after modified (9%) than original (91%) Griggs technique (p < 0.001). A moderate association between cartilage injury and increasing age was observed, whereas the level of intervention (p = 0.445) and to gender (p = 0.35) was not related to injury. Risk of cartilage injury decreased significantly (OR: 0.0264, 95%, CI: 0.005-0.153) with modified Griggs technique as determined in adjusted logistic regression model. DISCUSSION: Modified Griggs technique decreased the risk of tracheal cartilage injury significantly in our cadaver study. This observation may explain the decreased number of late tracheal stenosis after application of the modified Griggs method.

[General anesthesia during double balloon enteroscopy--Hungarian experiences]. / Kettosballon-enteroszkópiás vizsgálatoknál végzett altatások során szerzett hazai tapasztalatok. Beteg-autonómia az anesztéziában.

UNLABELLED: Double balloon enteroscopy needs sufficient sedation technique, because the examination is uncomfortable and lengthy. The most prevalent sedation method is conscious sedation world-wide. AIM: To demonstrate that double balloon enteroscopy examination can also be safely performed in general anesthesia with intubation and that this method can be an option in patients with severe multiple morbidities. METHODS: A retrospective evaluation of intubation narcosis in patients undergoing double balloon enteroscopy was performed at the 1st Department of Internal Medicine, Semmelweis University. Patients were grouped based on gender, age and physical state. Anesthesia records included the duration of anesthesia, the quantities of medications used and anesthesia-related complications. RESULTS: Data obtained from 108 general anesthesia cases were analyzed. There were no permanent anesthesia-related complications in the period examined. The most frequent side effects of anesthesia were hypotension (30.55%), desaturation (21.29%), and apnea (17.59%). These complications were significantly more frequent among patients with multiple morbidities; however, their incidence was not proportional with the quantity of the medications used or the duration of anesthesia. CONCLUSION: The findings confirm that the most important advantage of general anesthesia over other methods is that it ensures stable airways, which makes it easy to counter-act frequent complications such as desaturation, apnea and aspiration. The number of complications of anesthesia was higher among patients with multiple morbidities, but these complications could be easily overcome in all patient groups. Therefore, this method is highly recommended for patients with multiple morbidities. Intubation narcosis can be also a viable option of conscious sedation for patients without co-morbidities.

[Practice of treatment restriction in Hungarian intensive care units]. / A kezeléskorlátozás gyakorlata a hazai intenzív osztályokon.

UNLABELLED: End of life decisions affect most of patients in intensive care units, thus, it is important to know both local and international practice in accordance with law and ethical principles for intensive care physicians. AIM: To search for local customs of end of life decisions (withholding or withdrawing the therapy, shortening of the dying process), and to compare the data with the international literature. METHODS: In 2007-2008 the first Hungarian survey was performed with the purpose to learn more about local practice of end of life decisions. Questionnaires were sent out electronically to 743 registered members of Hungarian Society of Anesthesiology and Intensive Care. Respecting anonymity, 103 replies were statistically evaluated (response rate was 13.8%) and compared with data from other European countries. RESULTS: As expected, it turned out from replies that the practice of domestic intensive care physicians is very paternal and this is promoted by legal regulations that share a similar character. Intensive care physicians generally make their decisions alone (3.75/5 point) without respecting the opinion of the patient (2.57/5 point) the relatives (2.14/5 point) or other medical personnel (2.37/5 point). Furthermore, they prefer not to start a therapy rather than withdraw an ongoing treatment. Nevertheless, the frequency of end of life decisions (3-9% of ICU patients) is smaller than other European countries. CONCLUSIONS: There is a need for the expansion of patients' right in our country. For end of life decisions, self determinations must be supported and a dialogue must be established between lawmakers and physicians, in order to improve the legal support of this medical practice.

Double balloon enteroscopy examinations in general anesthesia.

AIM: To demonstrate that the double balloon enteroscopy (DBE) can be safely performed in general anesthesia with intubation. METHODS: We performed a retrospective examination between August 2005 and November 2008 among patients receiving intubation narcosis due to DBE examination. The patients were grouped based on sex, age and physical status. Anesthesia records included duration of anesthesia, quantity of medication used and anesthesia-related complications. We determined the frequency of complications in the different groups and their relation with the quantity of medication used and the duration of anesthesia. RESULTS: We compiled data for 108 cases of general anesthesia with intubation. We did not observe any permanent anesthesia-related complications; the most frequent side effects of anesthesia were hypotension (30.55%), desaturation (21.29%), and apnea (17.59%). These complications were significantly more frequent among patients with multiple additional diseases [hypotension (23.1% vs 76.9%, P = 0.005), de-saturation (12.3% vs 69.2%, P < 0.001) and apnea (7.7% vs 53.8%, P = 0.001)], however, their incidence was not proportional to the quantity of medication used or the duration of anesthesia. CONCLUSION: General anesthesia with intubation is definitely a viable option among DBE methods. It is highly recommended in patients with multiple additional diseases.

[Ethical and legal problems of informed consent]. / A tájékozott beleegyezés jogi és etikai problémái.

INTRODUCTION: The previously accepted paternalistic relationship between patients and doctors has changed in last century. The expectation for patients to be involved in medical decisions is growing, but this involvement cannot be imagined without informed consent, hence it became one of the most important elements of a physician's responsibilities. Although informed consent is broadly regulated legally in Hungary, experiences show that practical realization is insufficient. This is also represented in the large number of lawsuits in connection with the inadequate or wrong use of informed consent. The aim of this study was to survey for the first time in Hungary the state of informed consent by the analysis of written consents to anaesthesia. METHODS: The authors collected and studied written consents to anesthesia from 36 hospitals and clinics in Budapest. They studied among others the presence of the following formal elements: individual consent forms for anesthesia, signatures on forms etc. They also examined whether the consents contained all of the conventional elements of informed consent. RESULTS: 61% of hospitals had individual forms for consent to anesthesia. Every consent form required a signature by the patient and almost every form (except two) by the doctor as well. 39% of forms describe the medical treatment in detail and only 25% mention its advantages and disadvantages. 28% of them specify definite risks, but only 19% mention their probability. 67% of the documents refer to the possible need to extend intervention. Patients have to declare whether they permit urgent blood transfusion in 25 institutions (69%). In only two hospitals are patients informed of their rights to revoke consent or to resign from being informed of medical treatment. CONCLUSION: Although all institutions have written consent forms that adhere to legal regulations, in terms of their format and matter they leave much to be desired. It is especially conspicuous that possible risks are named in less than a fourth of all forms, thus they have to be mentioned verbally and this obviously is a source of later arguments. The authors believe that all invasive medical procedures require templates for consent forms put together by professional panels. These forms could then be adapted to all specific medical procedures of the hospital in question.

[Ethical aspects of resuscitation]. / Az újraélesztés etikai vonatkozásai.

The former typically paternalistic physician-patient relationship has changed gradually toward an autonomy based one in the second half of the 20th century. Patient's autonomy includes the right to refuse life-saving therapy in modern constitutional states. Hungarian law assures the right to refuse life-saving treatment as well. However to our knowledge no such therapy refusal has occurred since the law coming into force likely because of the rather strict regulations. Forgoing resuscitation is basically determined by two factors: autonomy of the patient, and medical futility. The alteration of the law's form can facilitate the lawful Do Not Resuscitate (DNR)orders for the sake of patient's autonomy. Qualitative futility is characterized by quality of life, which only the patient has the right to judge. Resuscitation protocols based on results of controlled studies can significantly improve both the success rate of resuscitations and the quality of life. Education plays a prominent role in this process as it was demonstrated in our prospective comparative study. According to author's study Hungarian DNR orders are paternalistic and patient autonomy plays a secondary role. It was also established that patient's autonomy significantly improved in the subgroup trained according to international standards. Hungarian results were compared to the results of a highly educated group in the second study. The results confirmed the presumption: the education of resuscitation according to international standards improves both the representation of patient's autonomy in DNR decisions, survival rate and quality of life.

Comparison of effects of different hand positions during cardiopulmonary resuscitation.

AIM: The technique of chest compression recommended in the recent international guidelines is different from that which was traditionally used in Hungary. While compression force, location, frequency and duty cycle are all identical, the position of the hand on the chest is different. The aim of our study was to compare these two methods concerning the area and location of the surface compressed on the chest wall. METHODS: Thirty-eight doctors were trained in both compression methods. Compressions were carried out on an AMBU Man-C manikin. The compressed surface, marked by using a carbon paper, was projected on to a standardised 10 mm x 10 mm matrix to measure the area and location. The chest surface was marked subsequently as green, yellow and red areas to identify the correct position, incorrect position and dangerous areas. All subjects did chest compressions using both techniques (I, International; H, traditional Hungarian) in a random order each for 30 s. RESULTS: The surface area compressed was significantly larger by the H method than the I method (73.46 (+/-17.11) versus 41.75 (+/-11.08), p<0.005). 8.07 (+/-1.91) cm2 of an area considered dangerous were compressed by the H method compared to 2.93 (+/-0.78) cm2 by the I method (p<0.005). CONCLUSION: Comparing the two different methods of chest compressions, the hand position recommended by the recent international guidelines seems to be more safe as it compresses a smaller area which might cause injury.

Ethical considerations behind the limitation of cardiopulmonary resuscitation in Hungary--the role of education and training.

INTRODUCTION: Although the long term success of cardiopulmonary resuscitation (CPR) is still less than hoped for, its value cannot be questioned when carried out appropriately in selected cases. Resuscitation frequently brings only short-term success, and several patients suffer severe consequences also causing an economic, medical and ethical burden to society. The issue of limitation of resuscitation, including Do Not Attempt Resuscitation (DNAR) and the termination of resuscitation has been surveyed in many European countries using a structured questionnaire. In Hungary no such comprehensive study has been conducted yet. The goal of this investigation was to recognise the ethical factors limiting resuscitation in Hungary. METHODS: We contacted 72 doctors personally during 2003, who were working actively at an intensive care unit (ICU) and asked them to answer a structured questionnaire in strict anonymity. We investigated the role of different ethical issues in beginning and suspending resuscitation efforts in conjunction with medical experience, sex, ideology, and education using a five point visual analogue scale. The answers given were categorised to autonomy, futility, obtainable quality of life, resource utilization, and to "another" category detailed later on. The questionnaire and the plan of this investigation was approved by the Semmelweis Medical University's Ethical Committee (SE-TUKEB 109/2003). RESULTS: The decision not to attempt resuscitation was mostly dictated by the opinion of the head of department and the doctor in charge of the patient (3.53 +/- 1.30), and after this the presumed obtainable quality of life (3.13 +/- 1.40), objective futility (3.11 +/- 0.94), and patient autonomy (2.02 +/- 1.63). The other objective (0.57 +/- 1.59), and subjective (1.04 +/- 1.21) factors, as well as resource utilization (0.29 +/- 0.66) played a less important role. The decision to terminate resuscitation efforts was mostly dictated by the objective futility criteria (3.39 +/- 0.88), obtainable quality of life (3.31 +/- 1.50), subjective futility (3.19 +/- 1.47), and autonomy (1.57 +/- 1.67) to a smaller extent. Among the doctors who participated in an appropriate-an internationally accredited (ERC/RC(UK)/AHA)-Advanced Life Support (ALS) training-the frequency of the appearance of the principle of modern bioethics-such as autonomy-was significantly higher and the same tendency could be observed in those who completed their studies at the medical university in the last 5 years. CONCLUSIONS: The results underline the original presumption that the Hungarian resuscitation practice is at first influenced by professional (or "thought to be professional") standpoints. The quality of life, and patient autonomy plays an important role in the decision making about limitation of resuscitation efforts. Current CPR education emphasizes the importance of ethical considerations, and this could be observed clearly in the answers.

Determinant role of education in the ethical aspects of resuscitation: a German/Hungarian comparison.

UNLABELLED: Introduction, objectives: Bioethical principles concerning Do Not Attempt Resuscitation (DNAR) orders are connected significantly with education according to our previous investigation. In order to confirm the hypothesis, Hungarian results were compared with the data gained from a highly qualified homogeneous group of German doctors, showing similar cultural traditions. METHODS: The questionnaire investigated the factors influencing DNAR orders as functions of intensive medical experience, ideological view and professional education, using a 5-point visual analogue scale. Answers were assigned to categories of autonomy, futility, obtainable quality of life, resource utilization and a category of other factors detailed later. RESULTS: The DNAR decision and termination of resuscitation are to almost the same extent determined by futility (3.29+-0.75; 3.49+-0.71) and obtainable quality of life (3.13+-1.31; 3.47+-1.34). The opinion of head of department was also important (3.24+-1.35; 3.23+-1.36). Patient's autonomy played an important role (3.15+-0.85; 2.36+-1.48) in decision making. In comparison with the Hungarian results, the only significant difference was found in the field of patient's autonomy in both not starting (p<0.0002) and terminating resuscitation (p<0.02) in favour of German doctors respecting it. DISCUSSION: The results support the original hypothesis that consideration of modern bioethical principles, and especially the patient's autonomy are related to the level of the doctor's education. Comparing to Hungarian data there is only a minimal difference in other bioethical points, while the population of German doctors interviewed appreciated the patient's autonomy significantly higher. There should be greater discussion of ethical considerations in cardiopulmonary resuscitation education.

[Ethics and law in intensive therapy]. / Etika és jog az intenzív terápiában.

INTRODUCTION: Intensive therapy is one of the newest areas of medicine. The patient who was thought to be hopeless yesterday is given a chance to survive. As in other fields of medicine parallel with their development, several ethical and legal problems arise and wait for solutions. AIMS: Two areas need urgent solutions especially at first ethical then at legal levels. These are the questions of life and death: where is the boundary of euthanasia and can the so called DNR ("Do Not Resuscitate") strategy be applied, which partial therapy withdrawal can be done compatibly with the basic ethical and legal requirement of protection of life. Important question as well, is that where lies the boundary of free self determination. How can be living wills be given when is it necessary to ask for the patient's consent, how much information is to be given to the patient. METHODS: Based on increasing experiences form Europe and the USA, some of the important fundamental principles of therapy withdrawal of intensive care therapy is outlined. Besides the above described questions, a short description of the Hungarian conditions will be given. RESULTS: Although the number of declarations given by professional corporations increase decisions of the jury help the medical practitioner in making his difficult decisions, but making the individual decision personal communication of the medical staff with the patient or his foster play an important role. Everything is the patient's right of free self determination based on the patient being properly informed. The ethical and even the legal attitude does not consider withdrawal of a widening circle of therapy to a form of euthanasia. CONCLUSIONS: In the mirror of international experiences concordance is reached in many aspects of therapy withdrawal in intensive care. In the mean time national regulations are not yet available, this is the reason, why based on the international declarations, keeping an eye on the Hungarian practice these regulations should be worked out in the near future.

[Role of percutaneous tracheostomy in intensive care: a review]. / A percutan tracheostomia helye az intenzív terápiában: áttekintés.

INTRODUCTION: Performing early tracheostomy is a possible solution during prolonged ventilation in order to decrease late complications. Considering the duration of procedure and the hazards concerning the patient transport the risk of operation is high in the critically ill patients. Therefore bedside percutaneous tracheostomy (PCT) plays an increasing role in intensive therapy. AIMS: For emphasizing the widening role of PCT in intensive care the procedures were analysed in the mirror of international experiences. After introducing short history of the procedure the improvement of techniques is presented. METHODS: A description of the experiences with the three main techniques is presented based on early original publications. Analyzing the results of comparative studies the risks and benefits of different methods were investigated in focus of the early and late complications. RESULTS: Comparing the percutaneous and surgical techniques significantly lower number of late complications were observed in PCT groups by several studies but there is a debate concerning the early hemorrhagic complications. Among the percutaneous techniques there was no significant difference between the occurrence of complications. The greatest experience has been gathered with the sequential dilatation technique. The duration of procedure was the only significant difference between the sequential and forceps dilatational technique. CONCLUSIONS: According to the international literature the percutaneous tracheostomy is the procedure of choice for prolonged airway management for high-risk intensive care patients. Concerning the elevated risk of operation the percutaneous techniques have significantly shorter duration and lower rate of late complications. Among the different percutaneous techniques the only significant difference was the duration of the procedure. The shortest procedure was the forceps dilatational technique.
