Improvement of quality of life (QOL) between 1 and 3-4 years after traumatic brain injury (TBI) in ICU patients.

BACKGROUND: Evaluation of changes in quality of life (QOL) in ICU patients several years after traumatic brain injury (TBI) is not well documented. METHODS: A prospective cohort study was conducted in all patients with TBI admitted between 2004 and 2008 to the ICU of Regional Hospital of Malaga (Spain). Functional status was evaluated by Glasgow Outcome Scale (GOS) and QOL by PAECC (Project for the Epidemiologic Analysis of Critical Care patients) questionnaire between 0 (normal QOL) to 29 points (worst QOL). RESULTS: A total of 531 patients. Median(Quartile1,Quartile 3) age: 35 (22, 56) years. After 3-4 years, 175 died (33%). Survivor QOL was deteriorated (median total PAECC score: 5 (0, 11) points) although 75.76% of patients who survived showed good functional situation (GOS normal or mild dysfunction). An improvement in QOL scores between 1 and 3-4 years was observed (median PAECC score differences between 3-4 years and 1 year: - 1(- 4, 0) points). QOL score improved during this interval of time: 62.6% of patients. Change in QOL was related by multivariate analysis to admission cranial-computed tomography scan (Marshall's classification), age, and Injury Severity Score (ISS), with the biggest improvement seen in younger patients and with more severe ISS. Basic physiological activities were maintained in the majority of patients. Subjective aspects and working activities improved between 1 and 3-4 years but with a high proportion still impaired in these items after 3-4 years. CONCLUSIONS: ICU patients with TBI after 1 year show improvement in QOL between 1 and 3-4 years, with the biggest improvement in QOL seen in younger patients and in those with more severe ISS.

Validation of the ICH score in patients with spontaneous intracerebral haemorrhage admitted to the intensive care unit in Southern Spain.

OBJECTIVE: Validation of the intracerebral haemorrhage (ICH) score in patients with a diagnosis of spontaneous ICH admitted to the intensive care unit (ICU). METHODS: A multicentre cohort study was conducted in all consecutive patients with ICH admitted to the ICUs of three hospitals with a neurosurgery department between 2009 and 2012 in Andalusia, Spain. Data collected included ICH, Glasgow Coma Scale (GCS) and Acute Physiology and Chronic Health Evaluation II (APACHE-II) scores. Demographic data, location and volume of haematoma and 30-day mortality rate were also collated. RESULTS: A total of 336 patients were included. 105 of whom underwent surgery. Median (IQR) age: 62 (50-70) years. APACHE-II: 21(15-26) points, GCS: 7 (4-11) points, ICH score: 2 (2-3) points. 11.1% presented with bilateral mydriasis on admission (mortality rate=100%). Intraventricular haemorrhage was observed in 58.9% of patients. In-hospital mortality was 54.17% while the APACHE-II predicted mortality was 57.22% with a standardised mortality ratio (SMR) of 0.95 (95% CI 0.81 to 1.09) and a Hosmer-Lemenshow test value (H) of 3.62 (no significant statistical difference, n.s.). 30-day mortality was 52.38% compared with the ICH score predicted mortality of 48.79%, SMR: 1.07 (95% CI 0.91 to 1.23), n.s. Mortality was higher than predicted at the lowest scores and lower than predicted in the more severe patients, (H=55.89, p<0.001), Gruppo Italiano per la Valutazione degli Interventi in Terapia Intensiva calibration belt (p<0.001). The area under a receiver operating characteristic (ROC) curve was 0.74 (95% CI 0.69 to 0.79). CONCLUSIONS: ICH score shows an acceptable discrimination as a tool to predict mortality rates in patients with spontaneous ICH admitted to the ICU, but its calibration is suboptimal.

Patients Admitted to Three Spanish Intensive Care Units for Poisoning: Type of Poisoning, Mortality, and Functioning of Prognostic Scores Commonly Used.

Objectives. To evaluate the gravity and mortality of those patients admitted to the intensive care unit for poisoning. Also, the applicability and predicted capacity of prognostic scales most frequently used in ICU must be evaluated. Methods. Multicentre study between 2008 and 2013 on all patients admitted for poisoning. Results. The results are from 119 patients. The causes of poisoning were medication, 92 patients (77.3%), caustics, 11 (9.2%), and alcohol, 20 (16,8%). 78.3% attempted suicides. Mean age was 44.42 ± 13.85 years. 72.5% had a Glasgow Coma Scale (GCS) ≤8 points. The ICU mortality was 5.9% and the hospital mortality was 6.7%. The mortality from caustic poisoning was 54.5%, and it was 1.9% for noncaustic poisoning (p < 0.001). After adjusting for SAPS-3 (OR: 1.19 (1.02-1.39)) the mortality of patients who had ingested caustics was far higher than the rest (OR: 560.34 (11.64-26973.83)). There was considerable discrepancy between mortality predicted by SAPS-3 (26.8%) and observed (6.7%) (Hosmer-Lemeshow test: H = 35.10; p < 0.001). The APACHE-II (7,57%) and APACHE-III (8,15%) were no discrepancies. Conclusions. Admission to ICU for poisoning is rare in our country. Medication is the most frequent cause, but mortality of caustic poisoning is higher. APACHE-II and APACHE-III provide adequate predictions about mortality, while SAPS-3 tends to overestimate.

Relationship between quality-of-life after 1-year follow-up and severity of traumatic brain injury assessed by computerized tomography.

PURPOSE: This paper studies the relationship between computed tomography (CT) scan on admission, according to Marshall's tomographic classification, and quality-of-life (QoL) after 1 year in patients admitted to the Intensive Care Unit (ICU) with traumatic brain injury (TBI). METHODS: This study used validated scales including the Glasgow Outcome Scale and the PAECC (Project for the Epidemiologic Analysis of Critical Care Patients) QoL questionnaire. RESULTS: We enrolled 531 patients. After 1 year, 171 patients (32.2%) had died (missing data = 6.6%). Good recovery was seen in 22.7% of the patients, while 20% presented moderate disability. The PAECC score after 1 year was 9.43 ± 8.72 points (high deterioration). Patients with diffuse injury I had a mean of 5.08 points vs 7.82 in those with diffuse injury II, 11.76 in those with diffuse injury III and 19.29 in those with diffuse injury IV (p < 0.001). Multivariate analysis found that QoL after 1 year was associated with CT Marshall classification, depth of coma, age, length of stay, spinal injury and tracheostomy. CONCLUSIONS: Patients with TBI had a high mortality rate 1 year after admission, deterioration in QoL and significant impairment of functional status, although more than 40% were normal or self-sufficient. QoL after 1 year was strongly related to cranial CT findings on admission.

Survival analysis of surgically evacuated supratentorial spontaneous intracerebral hemorrhage with intraventricular extension.

OBJECTIVE: To conduct a survival study and evaluation of surgical treatment in a cohort of patients with diagnosis of supratentorial spontaneous intracerebral hemorrhage (ICH). MATERIALS AND METHODS: The study included all consecutive patients with supratentorial ICH admitted to the Intensive Care Units of three Spanish hospitals with Neurosurgery Department between 2009 and 2012. DATA COLLECTED: age, APACHE-II, Glasgow Coma Score (GCS), and pupillary anomalies on admission, intracerebral hemorrhage (ICH) score, location/volume of hematoma, intraventricular hemorrhage (IVH), surgical evacuation alone or with additional external ventricular drain, and 30-days survival and at hospital discharge RESULTS: A total of 263 patients were included. Mean age: 59.74±14.14 years. GCS: 8±4 points, APACHE II: 20.7±7.68 points. ICH Score: 2.32+1.04 points. Pupillary anomalies were observed in 30%. The 30-day mortality: 51.3% (45.3% predicted by ICH-score), and 53.2% at hospital discharge. A significant difference (p=0.004) was observed in hospital mortality rates between surgically treated patients (39.7%, n=78) versus those conservatively managed (58.9%, n=185); specifically in those with IVH surgically treated (34.2%, n=38) versus non-operated IVH (67.2%, n=125), p<0.001. No significant difference was found between mortality rates in patients without IVH. Multiple logistic regression analysis showed an OR for surgery of 1.04 (95% CI; 0.33-3.22) in patients without IVH versus 0.19 (95% CI; 0.07-0.53) in patients with IVH (decreased mortality with surgical treatment). The propensity score analysis for IVH patients showed improved survival of operated group (OR 0.23, 95% CI; 0.07-0.75), p=0.01. CONCLUSIONS: Hospital mortality was lower in patients who underwent surgery compared to patients conservatively managed, specifically for the subgroup of patients with intraventricular hemorrhage.

Prolonged QT interval in ST-elevation myocardial infarction and mortality: new prognostic scale with QT, Killip and age.

AIMS: To analyze the relation between prolonged QT interval and mortality in patients with ST-elevation myocardial infarction and complementarity with Killip, Thrombolysis in Myocardial Infarction (TIMI) and Acute Physiology and Chronic Health Evaluation-II (APACHE-II) scales. METHODS: A nested cohort case-control study was conducted in a Spanish hospital. The cohort consisted of patients with ST-elevation myocardial infarction admitted between 2008 and 2010 (n = 524). The cases were the patients who died (n = 38) and the controls (n = 81) were a random sample of those who survived (one of every six). RESULTS: The corrected QT (QTc) interval of first ECG (prehospital-or-hospital admission) was prolonged in 18 of the 35 patients who died (51.4%) and in 12 of the controls (16.7%; P < 0.001). APACHE-II, TIMI and Killip scores were higher in the patients who had died (P < 0.001). Mortality with prolonged QTc (19.3%) was 20%, and 4.5% were with normal QTc (80.7%; P < 0.001).Logistic regression showed a relation between mortality with prolonged QTc and TIMI [odds ratio (OR) 3.57(1.16-10.97)]. A second model was constructed with APACHE-II and prolonged QTc [OR 6.47(1.77-23.59)]; receiver operating characteristic (ROC) curve area [0.92(0.87-0.97)], and individually, for APACHE-II was 0.88 (0.81-0.95). A new score was constructed: QTc (not prolonged: 0 points, prolonged: 7 points), age (<65 years: 0 points, 65-74 years: 6 points, ≥75 years: 9 points), Killip (I: 0 points, II-III: 4 points, IV: 17 points). ROC area: 0.88. CONCLUSIONS: Hospital mortality was higher with prolonged QTc at prehospital-or-hospital admission, given equal Killip, TIMI and APACHE values. Discrimination of Killip, TIMI and APACHE values can be improved with prolonged QTc. Discrimination of a model including Killip, age and prolonged QTc is quite good. We have made a new simple prognostic scale with these variables.

Kidney transplantation with grafts from type III Maastricht non-beating-heart donors.

Kidney transplantation (KT) with kidneys from non-beating-heart donors (NBHD) is a growing trend in Spain. The majority of these kidneys come from type II Maastricht patients, although in recent years, organ donations from patients awaiting cardiac arrest following limitation of life-sustaining therapy has already been in practice in certain European and North American countries, involving type III Maastricht patients. We present a series of 6 KT using kidneys from NHBD as a consequence of limitation of life-sustaining therapy in three different hospitals in the sector of Malaga. After agreeing upon a protocol for evaluating the potential of a patient for organ donation after the decision for limiting life-sustaining therapy, the patients' families were given the option of organ donation. Kidneys were preserved using a Porges double balloon catheter, which was placed prior to cardiac arrest. In two cases, the limitation of life-sustaining therapy took place in the intensive care unit, and in the third case, in the operating room. The interval between limitation of life-sustaining therapy and cardiac arrest ranged between 15 minutes and 40 minutes, with an interval of circulatory arrest prior to perfusion of 5-11 minutes. Perfusion-cooling of the kidneys was initially carried out using saline solution, followed by organ preservation solution (Celsior or Belzer) and extraction of the kidney using a rapid surgical technique. True or functional hot ischaemia times were 60 minutes, 59 minutes, and 50 minutes, respectively, for each of the three donors. Kidneys were evaluated for viability using time intervals for the procedure (including hypotension prior to cardiac arrest), macroscopic appearance, and histopathology of a sample taken from each kidney. The recipients of these 6 kidneys had given their consent to receive organs from expanded-criteria donors. Cold ischaemia lasted between 9 hours and 20 hours (mean: 14.6 hours). One recipient developed haemorrhagic complications during the immediate postoperative period and required a transplantectomy. The other five currently retain functioning grafts. All had delayed graft function, necessitating haemodialysis. The range of estimated glomerular filtration rates at the most recent follow-up evaluation was 23.0-106 ml/min/1.73 m(2). In conclusion, type III Maastricht donors provide valid kidneys for transplantation, although this series showed that supported functional hot ischaemia was very important, the consequence of accumulated ischaemic damage starting in the agonal phase, circulatory arrest, and organ preservation using cold solutions. As such, to improve the quality of results obtained using kidneys from these types of donors would involve a very careful selection of optimal donors and minimisation of total functional ischaemia times.

Bladder mucosal CO2 compared with gastric mucosal CO2 as a marker for low perfusion states in septic shock.

Recent reports indicate the possible role of bladder CO(2) as a marker of low perfusion states. To test this hypothesis, shock was induced in six beagle dogs with 1 mg/kg of E. coli lipopolysaccharide, gastric CO(2) (CO(2)-G) was measured with a continuous monitor, and a pulmonary catheter was inserted in the bladder to measure CO(2) (CO(2)-B). Levels of CO(2)-B were found to be lower than those of CO(2)-G, with a mean difference of 36.8 mmHg (P < 0.001), and correlation between both measurements was poor (r(2) = 0.16). Even when the correlation between CO(2)-G and ΔCO(2)-G was narrow (r(2) = 0.86), this was not the case for the relationship between CO(2)-B and ΔCO(2)-B (r(2) = 0.29). Finally, the correlation between CO(2)-G and base deficit was good (r(2) = 0.45), which was not the case with the CO(2)-B correlation (r(2) = 0.03). In our experience, bladder CO(2) does not correlate to hemodynamic parameters and does not substitute gastric CO(2) for detection of low perfusion states.

Paroxysmal sympathetic hyperactivity after traumatic brain injury: clinical and prognostic implications.

A proportion of patients surviving severe traumatic brain injury (TBI) have symptoms suggestive of excessive sympathetic discharge, here termed paroxysmal sympathetic hyperactivity (PSH). The goals of this study were: (1) to describe the clinical associations and radiological findings of PSH, its incidence, and features in subjects with severe TBI in the intensive care unit (ICU); (2) to investigate the potential role of increased intracranial pressure in the pathogenesis of PSH; and (3) to determine the prognostic influence of PSH during the ICU stay, on discharge from the ICU, and at 12 months post-injury. A prospective cohort study was undertaken of all ICU admissions with severe TBI older than 14 years over an 18-month period. The PSH symptoms consisted of paroxysmal increases in blood pressure, respiratory rate, and heart rate; worsening level of consciousness; muscle rigidity; and hyperhidrosis. Subjects demonstrating PSH episodes were compared with a group of non-PSH consecutive subjects studied over the first 6 months of the study period. Data were recorded on the clinical variables associated with PSH episodes, early post-injury cerebral CT findings, and neurological status at 1 year. Of 179 severe TBI patients admitted over the study period, 18 (10.1%) experienced PSH. Injury severity-related variables (e.g., initial APACHE II score, admission coma level, and proportion with intracranial hypertension) were similar between the two groups. The PSH group had a longer ICU stay and a greater incidence of infectious complications. At 1 year post-injury, 20% of this group demonstrated ongoing PSH episodes. Over 18 months, 10.1% of admissions following severe TBI demonstrated PSH features in ICU. Subjects with PSH had a longer ICU stay and higher rate of complications, although this did not appear to compromise their long-term neurological recovery.

Prognostic influence and computed tomography findings in dysautonomic crises after traumatic brain injury.

BACKGROUND: Dysautonomic crises represent a relatively unknown complication in patients with severe traumatic brain injury (TBI). Few studies have been undertaken of their pathophysiology and prognostic repercussions. We studied the prevalence of dysautonomic crises after TBI, their radiologic substrate, influence on the clinical course in the intensive care unit (ICU), and effect on neurologic recovery. METHODS: A case-control study involving 11 patients with dysautonomic crises admitted with TBI during a span of 1 year and 26 patients admitted with TBI but no crises during the first 3 months of the same year. The initial severity was assessed from Apache II, Glasgow Coma Scale (GCS) scores, and computed tomography (CT) during the first 24 hours. Complications were assessed by the duration of ICU stay, days on mechanical ventilation, need for tracheotomy, and number of infectious complications. Neurologic recovery was assessed with the GCS at discharge from the ICU and with the Glasgow Outcome Scale 12 months later. RESULTS: Both groups were similar at admission. The prevalence of dysautonomic crises was 9.3%. Patients with dysautonomic crises had more focal lesions on cranial CT than patients without crises, a significantly longer ICU stay, and a tendency to have a worse level of consciousness at discharge from the ICU but not 12 months later. CONCLUSIONS: Almost 10% of patients with severe TBI have dysautonomic crises during their ICU stay. Patients with dysautonomia were more likely to have focal intraparenchymal lesions, and crises were associated with greater morbidity and a longer ICU stay. Dysautonomic crises determined a worse short-term neurologic recovery.

Risk factors for renal dysfunction in the postoperative course of liver transplant.

Renal dysfunction (RD) is a frequent complication after orthotopic liver transplantation (OLT), and it has an unfavorable effect on the prognosis of OLT patients. The purpose of our study was to identify possible risk factors for RD and its impact on survival. The possible relations of pre-, peri-, and postoperative variables to early-onset renal dysfunction (ED) (within the 1st 3 months), late-onset renal dysfunction (LD) (between 3 and 6 months), and chronic renal dysfunction (CRD) (beyond 6 months) was analyzed. We studied 245 liver transplants in 241 patients. RD was found in 64.1% of these patients, and 69% of the patients with RD recovered. LD was found in 16.7% of the transplant patients. In the multivariate analysis, baseline serum creatinine, perioperative volume of transfused bank-red blood cells, Acute Physiology and Chronic Health Evaluation (APACHE) II score at intensive care unit (ICU) admission, and infection were associated with the development of RD. Overall mortality was 27.8% and for the RD group, it was 33.5%. LD, but not ED, was related to lower survival (together with graft dysfunction and APACHE II score at ICU admission). In conclusion, ED is frequent alter OLT and is related to preexisting RD, the volume of transfused bank--red blood cells during surgery, higher APACHE II score at ICU admission, and infection. In general, the prognosis for ED is good, in contrast with that of LD, which is associated with diminished survival.
