Endocrine abnormalities in critical care patients with moderate-to-severe head trauma: incidence, pattern and predisposing factors.

OBJECTIVE: To investigate the incidence and type of endocrine abnormalities in critical care patients with traumatic brain injury (TBI) and to examine their relationships to possible predisposing factors. DESIGN: Prospective study. SETTING: General intensive care unit in a university hospital. PATIENTS AND PARTICIPANTS: Thirty-four TBI patients (27 men, 7 women), having a mean age of 37+/-16 years, were studied after weaning from mechanical ventilation. INTERVENTIONS: Baseline endocrine assessment was carried out by measuring cortisol, corticotropin, dehydroepiandrosterone sulfate, free thyroxine, thyrotropin (TSH), testosterone, oestradiol, follicle stimulating hormone (FSH), luteinizing hormone, prolactin, growth hormone and insulin-like growth factor I. Dynamic evaluation was performed by human corticotropin releasing hormone and growth hormone releasing hormone in all patients. Male patients underwent additional investigation with gonadotropin-releasing hormone. Severity of neurological derangement was graded according to Glasgow Coma Scale (GCS), Marshall Computerized Tomographic Classification and intracranial pressure (ICP) levels. MEASUREMENTS AND RESULTS: Eighteen of the 34 patients (53%) had an abnormal result in at least one hormonal axis tested, with cortisol hyporesponsiveness and gonadal dysfunction being equally common, affecting 24% of patients. Endocrine abnormalities were associated with a higher brain CT-scan classification score ( p=0.02). The GCS on admission correlated positively with baseline FSH (r=0.37, p=0.03), peak FSH (r=0.41, p=0.03), testosterone (r=0.44, p=0.02) and TSH (r=0.39, p=0.03). There were no relations between ICP(max) and any baseline or dynamic hormone measurements. CONCLUSIONS: Patients with TBI receiving critical care show changes in their neuroendocrine responses, which depend upon clinical and radiological measures of head injury severity. Most common abnormalities include cortisol hyporesponsiveness and hypogonadism.

Health-related quality of life and disability in survivors of multiple trauma one year after intensive care unit discharge.

OBJECTIVE: To evaluate health-related quality of life and disability in multiple-trauma patients requiring intensive care unit management. DESIGN: A 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. RESULTS: A 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. CONCLUSIONS: The 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.

Hemorrhagic cardiac tamponade in critically ill patients with acute renal failure.

PURPOSE: The purpose of this study was to report the development, management, and follow up of tamponading uremic pericardial effusion in critically ill patients with acute renal failure. SETTING: The setting for this study was an adult, 24-bed tertiary multidisciplinary intensive care unit (ICU) of a university hospital. PATIENTS: The subjects were 5 critically ill patients with multiple organ failure including acute renal failure (ARF) that was slow to resolve. RESULTS: Renal involvement was attributed to renal hypoperfusion, sepsis and myoglobinuria. Continuous veno-venous hemofiltration (CVVH) was instituted early during hospitalization in 4 cases and lasted for 35 to 48 days; renal replacement therapy was not used in 1 case. Tamponade developed late in the course of ARF, after CVVH was discontinued in the 4 cases and was effectively managed with percutaneous pericardiocentesis under echocardiography and continuous catheter drainage of the pericardial sac for 48 to 72 hours. Hemorrhagic fluid (Hb 2.2-5.9 g/dL) with lymphocyte predominance was detected. Transient constrictive-like pericarditis findings were present in all patients after the procedure. All patients were discharged from the hospital in a good condition with normal serum and creatinine levels; 1-year follow up showed a normal echocardiogram. CONCLUSION: Awareness for the possibility of hemorrhagic pericarditis and cardiac tamponade is needed in ICU patients with ARF slow to resolve. Transient constrictive-like pericarditis may present after pericardiocentesis.
