Background
Pressure ulcers are common in acute and long-term care. However, critically ill patients usually have multiple risk factors for pressure ulcers.Objectives
The study was conducted to assess pressure ulcer incidence in intensive care patients, the factors related to pressure ulcer incidence and the course of pressure ulcers after the admission to an intensive care unit.Design
A longitudinal design.Setting
This study was carried out in cardiological and surgical intensive care of a general hospital and in a nephrological intensive care of a university hospital.Participants
All patients admitted to intensive care wards during the period from April until October 2006 were invited to take a part in the study. One hundred and twenty-one patients were involved in the study. The inclusion criteria were adult intensive care patients, males and females, all diagnosis were included. The exclusion criterion was patients whose age less than 18 years.Method
Each patient was assessed twice; first, upon admission and second upon discharge or death, or after 2 weeks if the patient was still in intensive care. The assessed data included pressure ulcer preventive measures, risk factors using Braden score, pressure ulcer characteristics and treatment. Additionally, incontinence supplies (urine/bowel) if used and the severity of illness using Acute Physiology and Chronic Health Evaluation (APACHE II score) were assessd.Results
This study revealed a total incidence of 3.3% (4.5% in nephrological patients and 2.9% in surgical patients). Sixteen patients with a total of 21 pressure ulcers were admitted to the intensive care units. During the patients’ stay at the intensive care units six pressure ulcers developed newly and five pressure ulcers healed. The mean of the APACHE II score of patients with new pressure ulcers (16.6) were higher than in patients without new pressure ulcers (11.5).Conclusion
Pressure ulcer incidence is low in this study compared to other studies. Pressure ulcers can be healed in intensive care patients. Using some preventive measures such as foam and alternating air pressure mattresses may help to decrease pressure ulcer development. Hydrocolloid dressing may help to increase the healing rate of pressure ulcers. 相似文献8.
Aims and objectives: The study aimed to evaluate the predictive validity and accuracy of a new pressure ulcer risk assessment scale in two Indonesia intensive care units (ICUs). Background: Several risk assessment scales have been designed to identify patients at risk of developing pressure ulcers in ICU. However, the relative weight of each variable that contributes to pressure ulcer development in these scales is not described to enable designing of a risk assessment scale. Currently, the risk factors contributing to pressure ulcer development include interface pressure, body temperature and cigarette smoking. Design: A prospective cohort study was conducted in two ICUs in Pontianak, Indonesia. Methods: A total of 253 patients were recruited to the study from both hospitals. Data collection included new risk assessment scale [i.e. the Suriadi and Sanada (S.S.) scale] scoring, demographic, pressure ulcer severity scores (based on the National Pressure Ulcer Advisory Panel) and skin condition measures. Using the S.S. scale, trained data collectors scored patients once and assessed the body temperature daily until patients were discharged. Additionally, daily data were also collected in relation to the patient‘s skin condition and stage of pressure ulcer. Results: Out of the 253 patients, 72 (28·4%) developed pressure ulcers. In ICU A, the incidence was 27%; pressure ulcers developed into stage I (41·7%), stage II (45·8%), stage III (10·4%) and stage IV (2·1%). In ICU B, the incidence was 31·6%; the development of pressure ulcers was 48% in stage I and 52% in stage II. Using the predictive validity test, the S.S. scale balanced sensitivity (81%) and specificity (83%) at a cut‐off score of 4. The area under the receiver‐operating characteristic curve was 0·888 (confidence interval: 0·84–0·93). Conclusion: The S.S. scale was found to be a valid risk assessment tool to identify the patients at risk of developing pressure ulcers in Indonesia ICU. 相似文献

BACKGROUND: Critically ill patients are at increased risk for pressure ulcers, which increase patients' morbidity and mortality. Quality improvement projects decrease the frequency of pressure ulcers. OBJECTIVES: To improve patients' outcomes by reducing the prevalence of pressure ulcers, identifying areas for improvement in prevention of pressure ulcers, and increasing the adoption of preventive strategies in an intensive care unit. METHOD: Quasi-experimental methods were used for this quality improvement project in which 563 surveys of patients' skin were performed during 22 audits conducted during a 26-month period. One-on-one clinical instruction was provided to bedside nurses during the surveys, and pressure ulcer data were displayed in the clinical area. RESULTS: The frequency of pressure ulcers of all stages showed an overall downward trend, and the prevalence decreased from 50% to 8%. The appropriate allocation of pressure-relieving devices increased from 75% up to 95% to 100%. The likely origin of the ulcer (ie, whether it was hospital or community acquired) and the anatomical site of the pressure ulcers did not change during the study period. CONCLUSIONS: This program was successful in reducing the prevalence of pressure ulcers among vulnerable intensive care patients and indicates that quality improvement is a highly effective formula for improving patients' outcomes that is easily implemented by using clinical expertise and existing resources. 相似文献

Delirium and neurologic impairment are extremely common in the intensive care setting, and their delayed identification is an important contributor to patient morbidity. Even in comatose patients, the clinical neurologic examination remains the most accurate and effective tool in assessing nervous system function. Rapid identification of neurologic deficits with a practical and easily reproducible neurologic examination is a core skill for effectively caring for critically ill patients. The purpose of this tutorial is to discuss techniques of neurologic examination and localization with an emphasis on comatose patients. Commonly encountered cases of encephalopathy and coma along with clinical pearls are presented. 相似文献

Background
The deleterious effects of elevated intra-abdominal pressure (IAP) have been known for more than a century. The proposed objectives were to measure changes in IAP and analyze increase-related factors and complications and whether high IAP and its persistence are related to complications and mortality in a predominantly medical intensive care unit.Methods
Over a 1-year period, we conducted a prospective cohort study in which IAP was measured using the bladder method. Hospitalization time, demographic variables, diagnosis on admission, APACHE II score, and clinical complications were recorded.Results
A total of 130 patients were studied. Overall mean IAP was 12.3 mm Hg (standard deviation [SD], 3.79; 95% confidence interval [CI], 11.7-13), and on the first day, 12.68 mm Hg (SD, 5.32; 95% CI, 11.8-13.6); maximum IAP was 16.4 mm Hg (SD, 4.6; 95% CI, 15.6-17.2). A positive correlation was found between IAP, APACHE (Acute Physiology And Chronic Health Evaluation) II, and age. Higher IAP values were independently associated with higher age, prolonged activated partial thromboplastin time, need for dialysis, and intolerance to enteral feeding. The value showing the best sensitivity and specificity in predicting mortality was persistence of IAP 20 mm Hg or greater for 4 days or more. The number of days with IAP 20 mm Hg or greater was a factor associated with a higher risk of death (odds ratio, 2.3). Patients who died showed a tendency to increased IAP.Conclusion
In this study, a threshold IAP of 20 mm Hg and its permanence over time were the best predictive factors of complications and mortality. Among other relationships, we also observed that older patients had higher IAP. High IAP was a cause of intolerance to enteral nutrition. 相似文献13.

Purpose
Although gastrointestinal motility disorders are common in critically ill patients, constipation and its implications have received very little attention. We aimed to determine the incidence of constipation to find risk factors and its implications in critically ill patientsMaterials and Methods
During a 6-month period, we enrolled all patients admitted to an intensive care unit from an universitary hospital who stayed 3 or more days. Patients submitted to bowel surgery were excluded.Results
Constipation occurred in 69.9% of the patients. There was no difference between constipated and not constipated in terms of sex, age, Acute Physiology and Chronic Health Evaluation II, type of admission (surgical, clinical, or trauma), opiate use, antibiotic therapy, and mechanical ventilation. Early (<24 hours) enteral nutrition was associated with less constipation, a finding that persisted at multivariable analysis (P < .01). Constipation was not associated with greater intensive care unit or mortality, length of stay, or days free from mechanical ventilation.Conclusions
Constipation is very common among critically ill patients. Early enteral nutrition is associated with earlier return of bowel function. 相似文献14.

OBJECTIVE: To evaluate the incidence and risks factors of atrial fibrillation (AF). DESIGN: Prospective, observational study. SETTING: A surgical intensive care unit of a university hospital. PATIENTS: All patients with new onset of AF admitted in the surgical intensive care unit during a 6-month period. INTERVENTIONS: None. MEASUREMENT AND MAIN RESULTS: Of the 460 patients included in the study, AF developed in 24 patients (5.3%). According to univariate analysis, age, preexisting cardiovascular disease, and previous treatment by calcium-channel blockers were significant predictors of AF. Patients with AF received significantly more fluids and catecholamines and experienced more sepsis, shock, and acute renal failure. Severity (Simplified Acute Physiologic Score II), intensive care unit workload (OMEGA), intensive care unit and hospital length of stay, and mortality were significantly increased in patients who developed AF. Multivariate analysis identified five independent predictors of AF: advanced age, blunt thoracic trauma, shock, pulmonary artery catheter, and previous treatment by calcium-channel blockers. CONCLUSIONS: In surgical intensive care unit patients, the incidence of AF is greater than in the general population but less than in the cardiac surgery unit. The onset of AF reflects the severity of the disease. Five independent risk factors of AF were identified in surgical intensive care unit patients. The withdrawal of a calcium-channel inhibitor was also an independent risk factor of AF, and the weaning of this treatment must be carefully evaluated. Blunt thoracic trauma increases the chances of developing AF, as does the presence of shock, especially septic shock. 相似文献

Oral care intervention to reduce incidence of ventilator-associated pneumonia in the neurologic intensive care unit 总被引:1,自引:0,他引:1
Lorraine B Fields 《The Journal of neuroscience nursing》2008,40(5):291-298
Ventilator-associated pneumonia (VAP) is a preventable secondary consequence of intubation and mechanical ventilation. VAP is pneumonia that develops in an intubated patient after 48 hours or more of mechanical ventilator support. Mechanically ventilated patients in neurologic and other intensive care units (ICUs) are at an increased risk of VAP due to factors such as decreased level of consciousness; dry, open mouth; and microaspiration of secretions. VAP can be prevented by initiating interventions from the Institute of Healthcare Improvement's VAP bundle, including (a) elevating the head of the bed of ventilated patients to 30 degrees, (b) preventing venous thromboembolism through use of sequential compression devices or anticoagulation, (c) administering gastric acid histamine2 blockers, (d) practicing good hand hygiene, (e) initiating early mobilization, and (f) performing daily sedation interruption at 10 am to evaluate neurologic status. The one intervention not included in the IHI bundle is oral hygiene. The purpose of this project is to support the premise that oral care, including timed toothbrushing, combined with the VAP bundle can mitigate and prevent the occurrence of VAP. Our project specifically addressed timed oral care of mechanically ventilated patients on a 24-bed stroke, neurologic, and medical ICU. Patients were randomized into a control group that performed usual oral care or an intervention group that brushed teeth every 8 hours. The results were immediate and startling, as the VAP rate dropped to zero within a week of beginning the every-8-hours toothbrushing regimen in the intervention group. The study was so successful that the control group was dropped after 6 months, and all intubated patients' teeth were brushed every 8 hours, maintaining the zero rate until the end of the study. 相似文献

Treatment of fever in the neurologic intensive care unit with a catheter-based heat exchange system 总被引:12,自引:0,他引:12
Diringer MN;Neurocritical Care Fever Reduction Trial Group 《Critical care medicine》2004,32(2):559-564
CONTEXT: Elevated temperature worsens injury in experimental focal and global ischemia and brain trauma. Fever is common in patients with acute neurologic illness and independently predicts poor outcome. Conventional means of treating fever are not very effective in this population. OBJECTIVE: To study the effectiveness of a catheter-based heat exchange system in reducing elevated temperatures in critically ill neurologic and neurosurgical patients. DESIGN, INTERVENTION, SETTING, AND POPULATION: This was a prospective randomized, non-blinded trial that compared conventional treatment of fever (acetaminophen and cooling blankets) with conventional treatment plus an intravascular catheter-based heat exchange system (Alsius, Irvine, CA). Patients admitted to one of 13 neurologic intensive care units in academic medical centers were eligible if they a) suffered subarachnoid hemorrhage, intracerebral hemorrhage, ischemic infarction, or traumatic brain injury; b) had a temperature >38 degrees C on two occasions or for >4 continuous hrs; and c) required central venous access. MAIN OUTCOME MEASURE: The fever burden (area under the curve >38 degrees C) for 72 hrs was compared in an intention to treat analysis. Safety of the catheter system was monitored. RESULTS: A total of 296 patients were enrolled over 20 months. Forty-one percent had subarachnoid hemorrhage, 24% had traumatic brain injury, 23% had intracerebral hemorrhage, and 13% had ischemic stroke. The groups were matched in terms of age, body mass index, sex, and Glasgow Coma Scale score distribution. Fever burden was 7.92 vs. 2.87 degrees C-hrs in the conventional group and catheter groups, respectively (64% reduction, p <.01). There was no higher rate of infection or the use of sedatives, narcotics, or antibiotics in the catheter group. The catheter did not significantly increase risk to the patient beyond that of a central catheter. CONCLUSIONS: The addition of this catheter-based cooling system to conventional management significantly improves fever reduction in neurologic intensive care unit patients. 相似文献
