Dimopoulou I, Anthi A, Mastora Z, Theodorakopoulou M, Konstandinidis A, Evangelou E, Mandragos K, Roussos C: Health-related quality of life and disability in survivors of multiple trauma one year after intensive care unit discharge. Am J Phys Med Rehabil 2004;83:171–176. ObjectiveTo evaluate health-related quality of life and disability in multiple-trauma patients requiring intensive care unit management. DesignA total of 87 survivors of multiple trauma, with a median age of 31 yrs and a median Injury Severity Score of 22, were enrolled in the present study. The Nottingham Health Profile, Glasgow Outcome Scale, and Rosser Disability Scale were used to assess the functional consequences of trauma 1 yr after intensive care unit discharge. ResultsA total of 64 of 87 patients had a problem in at least one of the six domains related to subjective health status. The most prevalent complaint was related to somatic subdimensions, but emotional functioning was also affected. Nottingham Health Profile part 2 showed that 63 of the survivors experienced problems in at least one of the daily activities. Of particular importance, inability to work was reported by 47% of the patients. Fifty-nine percent experienced moderate-to-severe disability as evaluated by Glasgow Outcome Scale and Rosser Disability Scale. High aggregate injury severity score along with severe head trauma were independent predictors of poor health-related quality of life and disability. ConclusionsThe majority of survivors of major trauma exhibit considerable levels of disability and impairment in health-related quality of life. Global injury severity score and degree of brain trauma determine functional limitations. This information may help in organizing long-term rehabilitation of multiple-trauma patients.

High prevalence of decreased cortisol reserve in brain-dead potential organ donors.

ObjectiveTo investigate the adrenocortical function in brain-dead patients, potential organ donors. DesignProspective study. SettingIntensive care units in two teaching hospitals. PatientsA total of 37 patients (28 men, nine women) with severe brain injury, having a mean age of 42 ± 18 yrs, were included in the study. Group A consisted of 20 brain-injured patients who did not deteriorate to brain death. Group B included 17 brain-injured patients who were brain dead; of these, ten patients developed brain death during ICU stay and seven patients were admitted to the ICU after clinical brain death. InterventionsIn all patients (group A and group B), a morning blood sample was obtained at admission to the ICU to determine baseline plasma cortisol. Subsequently, 1 &mgr;g of corticotropin (adrenocorticotropic hormone, Synacthen) was administered intravenously, and a blood sample was taken 30 mins after the injection. In group B patients who became brain dead while being treated in the ICU (n = 10), the same procedure was repeated the morning after the confirmation of brain death. Patients having a cortisol level of at least 18 &mgr;g/dL after the administration of adrenocorticotropic hormone were defined as responders. Measurements and Main ResultsAfter the occurrence of brain death, group B patients had significantly lower values for baseline (8.5 ± 6.2 vs. 17.0 ± 6.6 &mgr;g/dL, p < .001) and stimulated (16.9 ± 6.3 vs. 23.9 ± 5.7 &mgr;g/dL, p = .001) plasma cortisol compared with group A patients. Thirteen group B patients (76%) and two group A patients (10%) were nonresponders to adrenocorticotropic hormone (p < .001). In group B patients, baseline and stimulated cortisol concentrations were significantly related (r = .71, p = .001), whereas there was no correlation between baseline cortisol and the increment in cortisol (r = −.37, p = .15). Mean hormonal data of the ten brain-dead patients studied at admission in the ICU and after the occurrence of brain death were the following: baseline plasma cortisol (23.5 ± 11.4 vs. 6.8 ± 4.2 &mgr;g/dL, p = .003) and stimulated serum cortisol (28.8 ± 9.9 vs. 16.3 ± 4.3 &mgr;g/dL, p = .008). ConclusionsAdrenal cortisol secretion after dynamic stimulation is deficient in a substantial proportion of brain-dead potential organ donors.

Functional status and quality of life in long-term survivors of cardiac arrest after cardiac surgery

ObjectiveTo assess long-term survival, functional status, and quality of life in patients who experienced cardiac arrest after cardiac surgery. DesignProspective, observational study. SettingAn 18-bed, adult cardiac surgery intensive care unit in a tertiary teaching center. PatientsTwenty-nine cardiac surgery patients who suffered an unexpected cardiac arrest in the immediate postoperative period. InterventionsThe New York Heart Association classification and a questionnaire based on the Nottingham Health Profile were used to evaluate functional status and quality of life 4 yrs after hospital discharge. Measurements and Main Results Of the 29 patients who experienced cardiac arrest during the first 24 hrs after cardiac surgery, 27 patients (93%) were successfully resuscitated and 23 patients (79%) survived to hospital discharge. Evaluation 4 yrs postdischarge showed that, of the 29 patients, 16 patients (55%) were still alive (long-term survivors). Functional status assessment of long-term survivors revealed that 12 patients (75%) were grouped in New York Heart Association class I, 3 patients (19%) in class II, and 1 patient (6%) in class III. None of them had a neurologic deficit. They all were living independently at home, without need of any nursing care. No patient reported any abnormal emotional reactions, and six patients (38%) had mild sleep disturbances, such as early awaking. Regarding activities of daily living, 20% returned to work, 94% were able to look after their home, 96% had a social life, 63% were sexually active, 81% were involved in their hobbies, and 75% had gone on holidays. ConclusionsCardiac surgery patients who experience an unexpected cardiac arrest in the immediate postoperative period have a 55% chance of being alive 4 yrs postdischarge. The majority of these long-term survivors has a good outcome with respect to functional status and quality of life.

Treatment with bosentan in a patient with thalassemia intermedia and pulmonary arterial hypertension

To the editor: Pulmonary hypertension (PH) is a frequent complication and one of the leading causes of mortality in patients with hemolytic disorders.[1][1][⇓][2][⇓][3]–[4][4] The pathophysiology of PH in hemoglobinopathies is multifactorial including chronic tissue hypoxia, high cardiac

Prediction of prolonged ventilatory support in blunt thoracic trauma patients

ObjectiveTo identify predictors of prolonged (>7 days) mechanical ventilation (MV) in patients with blunt thoracic trauma.DesignProspective analysis of consecutive patients.SettingAdult intensive care unit (ICU) in a teaching, tertiary-care hospital.Patients and participantsSixty-nine patients (53 men, 16 women) with thoracic trauma having a median age of 35 (range 17–85) years and a median injury severity score (ISS) of 29 (range 14–41) were enrolled in the present study. Associated injuries included head–neck (77%), extremities (72%), external (67%), abdomen–pelvis (67%), and face (55%).InterventionsPatient surveillance and data collection.Measurements and resultsThirty-three (48%) of the 69 patients required prolonged ventilatory support, ranging in duration from 8 to 38 (median 18) days. Logistic regression analysis revealed that advancing age (odds ratio=1.04, p=0.04), severity of head injury (odds ratio=1.92, p=0.008), and bilateral thoracic injuries (odds ratio=12.80, p<0.0001) were significant and independent predictors of long-lasting MV. In contrast, gender, injuries affecting the other body regions (face, abdomen–pelvis, extremities, and external), laparotomy in patients with abdominal injury, or PaO2/FIO2 on admission in the ICU, were unrelated to prolonged MV.ConclusionsIn thoracic trauma patients admitted in the ICU, prolonged mechanical ventilation was primarily determined by presence of bilateral chest injuries, age, and degree of neurotrauma. This information may help in planning the long-term care of such patients.

Pulmonary hypertension in β thalassaemia

Pulmonary hypertension is one of the leading causes of morbidity and mortality in patients with haemolytic disorders and is a frequent finding in echocardiographic screening of patients with β thalassaemia. Substantial progress has been made in understanding of the multifactorial pathophysiology of pulmonary hypertension in β thalassaemia. Haemolysis, reduced nitric oxide bioavailability, iron overload, and hypercoagulopathy are among the main pathogenetic mechanisms. Various disease-directed therapeutic methods, such as transfusion, chelation, and splenectomy, have important roles in the development of pulmonary hypertension in β thalassaemia. Studies investigating the prevalence of pulmonary hypertension in β thalassaemia are mostly based on echocardiographic findings, and are thus limited by the scarcity of information derived from right heart catheterisation. Invasive pulmonary haemodynamic data are needed to clarify the true prevalence of pulmonary hypertension in β thalassaemia, to better understand the underlying pathophysiology and risk factors, and to define the optimum therapy for this devastating complication.

Pulmonary Hypertension in Parenchymal Lung Disease

Idiopathic pulmonary arterial hypertension (IPAH) has been extensively investigated, although it represents a less common form of the pulmonary hypertension (PH) family, as shown by international registries. Interestingly, in types of PH that are encountered in parenchymal lung diseases such as interstitial lung diseases (ILDs), chronic obstructive pulmonary disease (COPD), and many other diffuse parenchymal lung diseases, some of which are very common, the available data is limited. In this paper, we try to browse in the latest available data regarding the occurrence, pathogenesis, and treatment of PH in chronic parenchymal lung diseases.

Massive Rupture of a Hepatic Hydatid Cyst Associated with Mechanical Ventilation

UNLABELLED An 80-yr-old woman with a complicated Echinococcus cyst of the liver underwent endotracheal intubation with a simple endotracheal tube and conventional mechanical ventilation that led to massive rupture of the cyst into the bronchi followed by fatal anaphylactic shock. We believe that the currently recommended use of a double-lumen endotracheal tube during surgery in the pulmonary hydatid cysts should be extended to hydatid cysts of the liver with thoracic involvement. IMPLICATIONS We present a case of massive rupture of hepatic Echinococcus cyst associated with mechanical ventilation. We believe that the use of a double-lumen endotracheal tube could be crucial in the management of the hydatid cysts of the liver with thoracic involvement.

Chronic thromboembolic pulmonary hypertension (CTEPH) and coagulation defects: Before and after treatment

Background: Although CTEPH is a thromboembolic disorder, the effect of the coagulation process in the pathogenesis and progression of the disease has not been fully elucidated. Aims: To assess coagulation in CTEPH and to evaluate differences after the initiation of PH-specific treatment. Methods: We studied 20 CTEPH patients (not on anticoagulation therapy at the time of tests) and 20 controls. CTEPH patients were reevaluated 1 year after therapy initiation. We performed Platelet- Function Analyzer/PFA-100 testing, ADP and epinephrine/EPI induced Light Transmission Aggregometry/LTA, Thrombelastometry/ROTEM (na-TEM) and Endogenous Thrombin Potential/ETP essay. Results: Before treatment and when compared to controls, CTEPH patients presented prolonged PFA-100 closure times (174.8sec±27.3, p=0.003), lower EPI and ADP-LTA (43.9%±11.2, p Conclusions: Our data suggest that the observed coagulation defects in CTEPH persist even after PH treatment initiation. EPI-LTA was the only index displaying significant increase after treatment.
