An analysis is made of the controversial application of the theory of disproportionate damage in the anaesthetic act, due to the high inherent risk, and regardless of the seriousness and importance of the surgery being performed. The existence of a disproportionate damage, that is, damage not foreseen nor accountable within the framework of the professional performance of the anaesthetist, does not by itself determine the existence of liability on the part of the anaesthetist, but the demand from the professionals themselves for a coherent explanation of the serious disagreement between the initial risk implied by their actions and the final consequence produced. 相似文献

ObjectiveThe objective of our study was to determine the seizure control rate of cerebral hemispherectomies in adult patients with drug-resistant epilepsy.Materials and methodsA systematic review and individual patient data meta-analysis was carried out. Seven international databases and scientific meeting proceedings were reviewed. Individual patient data were analysed to establish potential factors associated with postoperative seizure control.ResultsEight articles that satisfied the pre-established selection criteria were identified.After a median follow-up of 70 months (interquartile range, 29-175.5), 79.4% of patients remained seizure-free. There were no statistically significant differences in age at onset of epilepsy, duration of epilepsy, age at surgery, time of follow-up, gender, surgical-laterality, aetiology and ictal EEG abnormalities between seizure-free patients and those with recurrences.ConclusionsCerebral hemispherectomy has a high seizure control rate in adult patients with drug-resistant epilepsy. None of the variables analysed in the present study were associated with surgical success. 相似文献

Background and objectivesPatients older than 75 years with ST-segment elevation myocardial infarction undergoing primary angioplasty in cardiogenic shock have high mortality. Identification of preprocedural predictors of short- and long-term mortality could be useful to guide decision-making and further interventions.MethodsWe analyzed a nationwide registry of primary angioplasty in the elderly (ESTROFA MI + 75) comprising 3576 patients. The characteristics and outcomes of the subgroup of patients in cardiogenic shock were analyzed to identify associated factors and prognostic predictors in order to derive a baseline risk prediction score for 1-year mortality. The score was validated in an independent cohort.ResultsA total of 332 patients were included. Baseline independent predictors of mortality were anterior myocardial infarction (HR 2.8, 95%CI, 1.4-6.0; P = .005), ejection fraction < 40% (HR 2.3, 95%CI, 1.14-4.50; P = .018), and time from symptom onset to angioplasty > 6 hours (HR 3.2, 95%CI, 1.6-7.5; P = .001). A score was designed that included these predictive factors (score “6-ANT-40”). Survival at 1 year was 54.5% for patients with score 0, 32.3% for score 1, 27.4% for score 2 and 17% for score 3 (P = .004, c-statistic 0.70). The score was validated in an independent cohort of 124 patients, showing 1-year survival rates of 64.5%, 40.0%, 28.9%, and 22.2%, respectively (P = .008, c-statistic 0.68).ConclusionsA preprocedural score based on 3 simple clinical variables (anterior location, ejection fraction < 40%, and delay time > 6 hours) may be used to estimate survival after primary angioplasty in elderly patients with cardiogenic shock and to guide preinterventional decision-making. 相似文献
