Utility of Coronary Artery Calcium Score for Coronary Artery Disease Screening among Severely Ill Liver Transplant Candidates: Case Series

Noninvasive cardiac stress testing is essential to screen liver transplant (LT) candidates for the presence of coronary artery disease (CAD). However, cardiac stress testing may not be clinically feasible in some patients, especially among those who require intensive care for an extended period of time, before being listed for LT. The utility of coronary artery calcium (CAC) score as a potential noninvasive screening test for CAD in place of cardiac stress testing among critically ill intensive care unit (ICU)-bound LT recipients has not been well studied. We report 4 LT recipients who were screened for CAD only with CAC score before listing for LT. Our results suggest that CAC score may be a useful test to screen for CAD in severely ill ICU-bound LT recipients with low risk for coronary heart disease, who are not candidates for cardiac stress testing. Such recipients requiring intensive care, with CAC score of 0A may safely forgo cardiac stress testing prior to LT. Future prospective studies with a bigger sample size and longer follow-up would be helpful to validate our findings.

The Long and Winding Road to Personalized Glycemic Control in the Intensive Care Unit.

In the critically ill adult, dysglycemia is a marker of disease severity and is associated with worse clinical outcomes. Close monitoring of glucose and use of insulin in critically ill patients have been done for more than 2 decades, but the appropriate target glycemic range in critically ill patients remains controversial. Physiological stress response, levels of inflammatory cytokines, nutritional intake, and level of mobility affect glycemic control, and a more personalized approach to patients with dysglycemia is warranted in critically ill intensive care unit (ICU) patients. We discuss the pathophysiology and downstream effects of altered glycemic response in critical illness, management of glycemic control in the ICU, and future strategies toward personalization of critical care glycemic management.

Outcome of Patients Admitted with Exertional Heat Related Illness in Intensive Care Unit of Tertiary Care Hospital

Introduction: Exertional heat related illness particularly heat stroke is very common life threatening condition that frequently occur in young military trainee due to high ambient temperature and humidity.
 Objective: The study was undertaken to identify its outcome in recruits admitted in intensive care units of military tertiary care hospital.
 Methods: An observational cross-sectional descriptive study was done among those recruits admitted in Intensive Care Unit of military tertiary care hospital with diagnosis of heat related illness from June 2016 to August 2017 A.D. Data based on hospital case records were collected and analyzed using SPSS version 22. Primary outcome studied was mortality. Secondary outcomes studied were length of stay in ICU, hospital and on ventilator.
 Results: Out of 17 recruits, 12 were diagnosed as heat exhaustion and 5 were diagnosed as heat stroke. SOFA score for heat stroke and heat exhaustion patients ranged from 2-16 and 0- 2 with respective mortality rate 7-95% and 0-7%. APACHE II score for heat stroke and heat exhaustion patients ranged from 5-33 and 0-5 with respective mortality rate 5.80-73% and 0-5.80%. There was no mortality among 12 heat exhaustion patients. Out of 5 heat stroke patients, 3 died with 60% mortality rate. Heat stroke patients had maximum stay of 4 days in ICU, hospital for 5 days and ventilator for 4 days.
 Conclusion: Exertional heat related illness is common in young military trainee with heat exhaustion and heat stroke being common causes for ICU admission. Heat stroke has higher mortality rate due to multiple organ dysfunction.

Correlation between the invasive fungal infection among and their blood glucose levels

AbstractThe purpose of this study was to study the association of deep fungal infection with glucose levels in critically ill intensive care unit (ICU) patients. Fasting blood glucose level was measured for 108 critically ill ICU patients in the morning. After analyzed according to the Spearman method found deep fungal infections in patients with the rise in blood glucose levels and the ratio increases, a positive correlation between the two. Deep infection in critically ill ICU patients and their blood glucose levels was closely related, and therefore, there should a focus on controlling blood sugar levels in patients.

Children's and young people's experiences of a parent's critical illness and admission to the intensive care unit: A qualitative meta-synthesis.

Little is known about how children and young people experience and manage the critical illness of a parent and a parent's admission to the intensive care unit (ICU). The aim of this study was to search and interpret the existing literature describing children's and young people's experiences of a parent's illness trajectory in the ICU. A qualitative meta-synthesis was conducted based on a systematic literature search of online databases. Four main themes were identified and synthesised to describe the integrated experiences of children and young people: (a) the parent-child bond, (b) the unfamiliar environment, (c) the impact of the illness and (d) the experience of being overseen as close family members. Experiencing a parent's critical illness and admittance to the ICU is overwhelming. The bond between the parent and child is exposed by the separation from the ill parent. To comprehend and manage the experience, children and young people seek information depending on their individual capacities. They express a need to be close to their ill parent and to be seen and approached as close members of the family. However, children experience being overseen in their needs for support during their parent's ICU illness with the risk of being left in loneliness, sadness and lack of understanding of the parent's illness. Children and young people as relatives need to be acknowledged as close members of the family, when facing the illness trajectory of a parent, who is admitted to the ICU. They need to be seen as close family members and to be approached in their needs for support in order to promote their well-being during a family illness crisis. Early supportive interventions tailored to include children of the intensive care patient are recommended.

Determination of vancomycin pharmacokinetics in critically ill intensive care unit patients in Malaysia: A population pharmacokinetic analysis with a nonparametric approach

Background: The pharmacokinetics (PK) of vancomycin in critically ill intensive care unit (ICU) patients is difficult to predict due to the scarcity of data and the variable physiology of the patient cohort. Aims and Objectives: Since there are limited studies worldwide, this study is, therefore, intended to explore vancomycin population PK parameters in critically ill ICU patients in Hospital Raja Perempuan Zainab II, Kelantan, Malaysia. Materials and Methods: Vancomycin population PK in ICU patients was modeled with Pmetrics. A total of 92 samples from 45 ICU patients were included in the model building and validation. The median observations per patient were three with a range of one to four observations. The median parameters estimates obtained from the final model were used to predict individual vancomycin clearance (CL) in the validation dataset. Results: The PK of vancomycin was adequately described with a two-compartment model. Parameters included CL of 1.64 L/h, volume of distribution in central compartment of 20.0 L, rate of constant from central out to the peripheral compartment of 2.92/h, and the rate constant back from the peripheral to central compartment of 7.17/h. The developed model adequately estimated CL in the validation dataset. Conclusion: A model to describe the PK of vancomycin was developed which adequately describes vancomycin population PK in critically ill ICU patients in Kelantan. The model might be used in initiating a vancomycin dosage regimen in the type of patients similar to the present study.

Muscle-specific differences in expression and phosphorylation of the Janus kinase 2/Signal Transducer and Activator of Transcription 3 following long-term mechanical ventilation and immobilization in rats.

Muscle wasting is one of the factors most strongly predicting mortality and morbidity in critically ill intensive care unit (ICU). This muscle wasting affects both limb and respiratory muscles, but the understanding of underlying mechanisms and muscle-specific differences remains incomplete. This study aimed at investigating the temporal expression and phosphorylation of the Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway in muscle wasting associated with the ICU condition to characterize the JAK/STAT proteins and the related changes leading or responding to their activation during exposure to the ICU condition. A novel experimental ICU model allowing long-term exposure to the ICU condition, immobilization and mechanical ventilation, was used in this study. Rats were pharmacologically paralysed by post-synaptic neuromuscular blockade and mechanically ventilated for durations varying between 6hours and 14days to study muscle-specific differences in the temporal activation of the JAK/STAT pathway in plantaris, intercostal and diaphragm muscles. The JAK2/STAT3 pathway was significantly activated irrespective of muscle, but muscle-specific differences were observed in the temporal activation pattern between plantaris, intercostal and diaphragm muscles. The JAK2/STAT3 pathway was differentially activated in plantaris, intercostal and diaphragm muscles in response to the ICU condition. Thus, JAK2/STAT3 inhibitors may provide an attractive pharmacological intervention strategy in immobilized ICU patients, but further experimental studies are required in the study of muscle-specific effects on muscle mass and function in response to both short- and long-term exposure to the ICU condition prior to the translation into clinical research and practice.

A Two-Biomarker Model Predicts Mortality in the Critically Ill with Sepsis.

Improving the prospective identification of patients with systemic inflammatory response syndrome (SIRS) and sepsis at low risk for organ dysfunction and death is a major clinical challenge. To develop and validate a multibiomarker-based prediction model for 28-day mortality in critically ill patients with SIRS and sepsis. A derivation cohort (n = 888) and internal test cohort (n = 278) were taken from a prospective study of critically ill intensive care unit (ICU) patients meeting two of four SIRS criteria at an academic medical center for whom plasma was obtained within 24 hours. The validation cohort (n = 759) was taken from a prospective cohort enrolled at another academic medical center ICU for whom plasma was obtained within 48 hours. We measured concentrations of angiopoietin-1, angiopoietin-2, IL-6, IL-8, soluble tumor necrosis factor receptor-1, soluble vascular cell adhesion molecule-1, granulocyte colony-stimulating factor, and soluble Fas. We identified a two-biomarker model in the derivation cohort that predicted mortality (area under the receiver operator characteristic curve [AUC], 0.79; 95% confidence interval [CI], 0.74-0.83). It performed well in the internal test cohort (AUC, 0.75; 95% CI, 0.65-0.85) and the external validation cohort (AUC, 0.77; 95% CI, 0.72-0.83). We determined a model score threshold demonstrating high negative predictive value (0.95) for death. In addition to a low risk of death, patients below this threshold had shorter ICU length of stay, lower incidence of acute kidney injury, acute respiratory distress syndrome, and need for vasopressors. We have developed a simple, robust biomarker-based model that identifies patients with SIRS/sepsis at low risk for death and organ dysfunction.

Baseline serum bicarbonate levels independently predict short-term mortality in critically ill patients with ischaemic cardiogenic shock.

Cardiogenic shock is a feared complication of acute myocardial infarction with high mortality rates. Data on the predictive role of acid base dysregulation in this clinical setting are sparse. We therefore embarked on investigating the predictive role of serum bicarbonate in critically ill intensive care unit (ICU) patients with cardiogenic shock. A total of 165 ischaemic cardiogenic shock patients (118 men, aged 68.4 years (interquartile range 59.0-77.4), APACHE II score 26.0 (interquartile range 21.0-29.0), after percutaneous coronary intervention were included in a single-centre analysis. Percutaneous coronary intervention-related data such as left ventricular ejection fraction and laboratory indices were recorded and routine clinical follow-up was obtained at hospital discharge and at one year. All-cause mortality was assessed and data were analysed using univariate and multivariate models. All-cause mortality was highest (17%) during the first 48 hours following ICU admission (28-day mortality rate 43%). In a multiple regression model, age (hazard ratio (HR) 1.035, 95% confidence interval (CI) 1.011-1.059, P=0.004), APACHE II score (HR 1.036, 95% CI 1.002-1.072, P=0.037) and baseline serum bicarbonate levels (HR 0.93, 95% CI 0.866-0.998, P=0.046) independently predicted 28-day mortality (overall model fit χ2 22.9, P<0.0001). The HR for patients in the lowest baseline serum bicarbonate tertile for 365-day mortality was HR 2.06 (95% CI 1.20-3.53). In a large cohort of consecutive cardiogenic shock patients hospitalised in the ICU, low serum bicarbonate levels at admission independently predicted mortality. Given the widespread availability of blood gas analysers in ICUs, we propose baseline serum bicarbonate levels as an additional biomarker for identification and stratification of cardiogenic shock patients at risk.

Low circulating coenzyme Q10 during acute phase is associated with inflammation, malnutrition, and in-hospital mortality in patients admitted to the coronary care unit.

Coenzyme Q10 (CoQ10) has a potential role in the prevention and treatment of heart failure through improved cellular bioenergetics. In addition, it has antioxidant, free radical scavenging, and vasodilatory effects that may be beneficial. Although critical illness in intensive care unit is associated with decreased circulating CoQ10 levels, the clinical significance of CoQ10 levels during acute phase in the patients of cardiovascular disease remains unclear. We enrolled 257 consecutive cardiovascular patients admitted to the coronary care unit (CCU). Serum CoQ10 levels were measured after an overnight fast within 24h of admission. We examined the comparison of serum CoQ10 levels between survivors and in-hospital mortalities in patients with cardiovascular disease. Serum CoQ10 levels during the acute phase in patients admitted to the CCU had similar independent of the diagnosis. CoQ10 levels were significantly lower in patients with in-hospital mortalities than in survivors (0.43±0.19 vs. 0.55±0.35mg/L, P=0.04). In patients admitted to the CCU, CoQ10 levels were negatively associated with age and C-reactive protein levels, and positively associated with body mass index, total cholesterol, and high-density lipoprotein cholesterol levels. Low CoQ10 levels correlated with low diastolic blood pressure. Multivariate logistic regression analysis demonstrated that low CoQ10 levels were an independent predictor of in-hospital mortality. Low serum CoQ10 levels during acute phase are significantly associated with cardiovascular risk and in-hospital mortality in patients admitted to the CCU.

Usability Testing of an Electronic Patient-Reported Outcome System for Survivors of Critical Illness.

Web-based electronic patient-reported outcomes (ePRO) measures are increasingly used to facilitate patient-centered health assessments. However, it is unknown if ePRO completion is feasible for recently ill intensive care unit (ICU) survivors and their families. To develop and evaluate the usability of a novel ePRO system (ePRO to Support People and Enhance Recovery [ePROSPER]) among ICU survivors and their families within an ongoing clinical trial. Paper-based PROs were iteratively adapted to electronic forms (ePROs). Then, the usability of ePROSPER was assessed among 60 patients, their family members, and PRO and programming experts via questionnaires (eg, Systems Usability Scale), "think aloud" open-ended feedback, task completion times, and error rates. Input from patients and their families was used to incorporate user-experience modifications into ePROSPER. This feedback also led to inclusion of automated reminders for questionnaire completion and real-time alerts for staff triggered by high symptom levels. Median usability scores increased over testing cycles from 40 to 73 to 95, nearing the maximum score and showing excellent usability. All users completed ePROSPER within 20 minutes; 87% preferred it to a written version. ePROSPER was then implemented in a clinical trial without data errors. Automated ePRO systems can be successfully integrated in a post-ICU clinical trial setting. The value of integrating such systems in direct clinical care should be assessed in future studies.

Challenges in Individualizing Drug Dosage for Intensive Care Unit Patients: Is Augmented Renal Clearance What We Really Want to Know? Some Suggested Management Approaches and Clinical Software Tools.

Acutely ill intensive care unit (ICU) patients often have large apparent volumes of distribution of drugs and, because of this, their drug clearance (CL) is usually also increased. 'Augmented renal Cl' is a current issue in the management of drug therapy for acutely ill and unstable ICU patients; however, Cl, the product of volume and the rate constant for excretion, describes only a theoretical volume of drug cleared per unit of time. Information of the actual rate of movement of the drug itself is obscured. It is suggested that the most useful clinical information is given by describing drug volume and elimination rate constant separately. This also permits better understanding of the patient's separate issues of fluid balance and drug elimination, especially when dialysis, renal replacement therapy, or extracorporeal membrane oxygenation (ECMO) may be used, and facilitates management of these two important separate clinical issues. Optimal management of drug therapy also requires optimal methods embodied in clinical software to describe drug behavior in these highly unstable patients, and considerably more data than for ordinary patients. The interacting multiple model (IMM) clinical software facilitates management of both fluid balance and drug therapy in these unstable patients. Illustrative cases are discussed, and new monitoring and management strategies are suggested. Like other ICU skills, physicians need to learn optimal tools for managing drug therapy in the ICU. Further work should help evaluate these new approaches.

Awake or Sedated: Trends in the Evaluation and Management of Agitation in the Intensive Care Unit.

Critically ill intensive care unit (ICU) patients often require sedation to tolerate life-saving interventions such as mechanical ventilation. Pain, anxiety, and delirium all contribute to patient distress and agitation which can interfere with ICU medical care if not addressed and treated appropriately. Sedation practices to treat pain, anxiety, and delirium that deviate from established practice guidelines affect mechanical ventilation duration, ICU and hospital length of stay, functional impairment, and mortality. Historically patients were kept deeply sedated in the ICU. However, considerable research has demonstrated that minimizing sedation with the goal to achieve comfortable wakefulness is preferred in most ICU patients and is associated with improved clinical outcomes. This review will focus on changes in sedation practice in the ICU over the past three decades. With the implementation of validated sedation assessment scales, a multidisciplinary treatment model, and development of daily awakening protocols, no or minimal sedation can be achieved in the majority of ICU patients. Frequent, careful consideration of the environmental stimuli that contribute to patient discomfort and agitation and judicious use of sedative medications individualized to each patient are important in achieving this goal.

Predictive Value of Short-Term EEG Recording in Critically ill Adult Patients

ABSTRACTWe assessed the EEG patterns and their prognostic significance in critically ill adult patients with encephalopathy, by digital EEGs lasting up to 1 hour. Of the 110 patients (age: 43.8 ± 19.4 years, male:female:1.6:1) studied, 32% had hypoxic ischemic encephalopathy (HIE), 17% severe infections, and 14.5% stroke. Observed EEG patterns were diffuse slowing (41%), low-voltage cerebral activity (LVCA, 18%), nonconvulsive status epilepticus (NCSE, 13.6%), and periodic abnormalities (9.1%). LVCA, age, Glasgow Coma Score (GCS) < 8, HIE, and modified Hockaday’s EEG grades of IV and V were associated with poor outcome (p < 0.005) at hospital discharge; generalized slowing was associated with a relatively good outcome (p = 0.003). On multivariate analysis, factors independently predictive of mortality were LVCA, older age, and poor GCS. In conclusion, LVCA and generalized background slowing were common EEG patterns among critically ill intensive care unit (ICU) patients with encephalopathy of varied etiologies. While LVCA was associated with a poor outcome, generalized background slowing predicted better prognosis. Conventional short-duration, bedside EEG studies could aid in the recognition of electrographic patterns of prognostic importance in facilities where continuous EEG monitoring is lacking.

Adrenal Insufficiency In Critically Ill Patients

Adrenal insufficiency means hypo function of the adrenal cortex, usually resulting in low glucocorticoid level and it may be associated with low mineralocorticoid, rarely low adrenal androgen level. It can be categorized into two types: primary and secondary. Primary adrenal insufficiency or Addison's disease is associated with low cortisol and high ACTH level. Secondary/tertiary adrenal insufficiency is due to pituitary or hypothalamic disorders and is associated with both low cortisol and ACTH level. Among critically ill patients (CIP) adrenal insufficiency is not uncommon. The reported incidence of adrenal insufficiency varies greatly depending on the population of critically ill patients studied, the type of test, cut off levels used, and the severity of illness. Several studies have shown increased mortality in patients with very low or very high baseline cortisol levels. Manifestations of adrenal insufficiency in the critically ill patient are numerous and nonspecific, so clinicians are urged to have a high index of suspicion while taking history and doing physical examination and be alert to important diagnostic clues, such as hyponatremia, hyperkalemia, and hypotension, that are refractory to fluids and vasopressor without any clear causation. In current literature there is no consensus level of cortisol (basal/random/stimulated) in critically ill subjects. But it is shown that both high and low cortisol level is associated with increased mortality. In one study Basal Serum Cortisol &lt;414 nmol/L and &gt; 696 nmol/L is shown as indicative of higher risk among critically ill patients. Even with Septicemia or ARDS all subjects don’t suffer from adrenal insufficiency often termed relative adrenal insufficiency or critical illness associated adrenal insufficiency. It has been observed that short term low dose IV hydrocortisone may be beneficial in selective group of patients in intensive care unit (ICU) with critical illness. Diagnosis of adrenal insufficiency associated with critical illness is still challenging for physicians working in ICU. Treatment should be started without delay in emergency situation with Injection Hydrocortisone intravenously or even intramuscularly. Since the condition appears to be common in patients with septic shock, clinicians should have a high index of suspicion for its occurrence in critically ill patients with persistent hypotension despite adequate fluid resuscitation and/or poor hemodynamic response to vasopressor. Adrenal insufficiency associated with other illnesses in ICU are attributed to previous primary or secondary adrenal insufficiency. Treatment with physiologic doses of corticosteroids should be started as soon as possible since short-term treatment carries very few risks and has been shown to decrease both morbidity and mortality. Only suspected cases should be evaluated and could be treated with 100-200 mg Hydrocortisone in divided doses for 5-7 days. Glucocorticoid cannot be recommended as a routine adjuvant therapy in all cases of septic shock or ARDS. But glucocorticoid earned its position among other rescue strategies in subgroups of ICU patients with the highest mortality risk. Steroid use is an art and needs to be used by experienced physician. Otherwise it may do more harm than benefit.Bangladesh Crit Care J March 2015; 3 (1): 27-30

Patients' experiences of technology and care in adult intensive care.

To investigate patients' experiences of technology in an adult intensive care unit. Technology is fundamental to support physical recovery from critical illness in Intensive Care Units. As well as physical corollaries, psychological disturbances are reported in critically ill patients at all stages of their illness and recovery. Nurses play a key role in the physical and psychological care of patients;, however, there is a suggestion in the literature that the presence of technology may dehumanise patient care and distract the nurse from attending to patients psychosocial needs. Little attention has been paid to patients' perceptions of receiving care in a technological environment. This study was informed by Heideggerian phenomenology. The research took place in 2009-2011 in a university hospital in England. Nineteen participants who had been patients in ICU were interviewed guided by an interview topic prompt list. Interviews were transcribed verbatim and analysed using Van Manen's framework. Participants described technology and care as inseparable and presented their experiences as a unified encounter. The theme 'Getting on with it' described how participants endured technology by 'Being Good' and 'Being Invisible'. 'Getting over it' described why participants endured technology by 'Bowing to Authority' and viewing invasive technologies as a 'Necessary Evil'. Patients experienced technology and care as a series of paradoxical relationships: alienating yet reassuring, uncomfortable yet comforting, impersonal yet personal. By maintaining a close and supportive presence and providing personal comfort and care nurses may minimize the invasive and isolating potential of technology.

Neuromuscular blockade improves first-attempt success for intubation in the intensive care unit. A propensity matched analysis.

The use of neuromuscular blocking agents (NMBAs) has been shown to be valuable in improving successful tracheal intubation in the operating room and emergency department. However, data on NMBA use in critically ill intensive care unit (ICU) patients are lacking. Furthermore, there are no data on NMBA use with video laryngoscopy. To evaluate the effect of NMBA use on first-attempt success (FAS) with tracheal intubation in the ICU. Single-center observational study of 709 consecutive patients intubated in the medical ICU of a university medical center from January 1, 2012 to June 30, 2014. Data were collected prospectively through a continuous quality improvement program on all patients intubated in the ICU over the study period. Data relating to patient demographics, intubation, and complications were analyzed. We used propensity score (propensity to use an NMBA) matching to generate 5,000 data sets of cases (failed first intubation attempts) matched to controls (successful first attempts) and conditional logistic regression to analyze the results. There were no significant differences in patient demographics, except median total difficult airway characteristics were higher in the non-NMBA group (2 vs. 1, P < 0.001). There were significant differences in the sedative used between groups and the operator level of training. More patients who were given NMBAs received etomidate (83 vs. 35%) and more patients in the non-NMBA group received ketamine (39 vs. 9%) (P < 0.001). The FAS for NMBA use was 80.9% (401/496) compared with 69.6% (117/168) for non-NMBA use (P = 0.003). The summary odds ratio for FAS when an NMBA was used from the propensity matched analyses was 2.37 (95% confidence interval, 1.36-4.88). In the subgroup of patients intubated with a video laryngoscope, propensity-adjusted odds of FAS with the use of an NMBA was 2.50 (1.43-4.37; P < 0.001). There were no differences in procedurally related complications between groups. After controlling for potential confounders, this propensity-adjusted analysis demonstrates improved odds of FAS at intubation in the ICU with the use of an NMBA. This improvement in FAS is seen even with the use of a video laryngoscope.

Assessment of the Safety and Efficacy of Bedside Ultrasound Guidance for Inferior Vena Cava Filter Placement in Critically Ill Intensive Care Unit Patients

Inferior vena cava filters (IVCFs) have been used clinically for approximately 45 y, but only a few studies of these devices have involved intensive care unit (ICU) patients who were critically ill and had multiple-organ dysfunction or were otherwise too unstable for transport. The purpose of this research was to assess the tolerability and efficacy of bedside ultrasound-guided IVCF placement in ICU patients. A retrospective analysis of both bedside ultrasound-guided and X-ray-guided ICVF placement was performed from November of 2011 to August of 2013. The total success rate for ultrasound-guided IVCF placement was 93.4%, which included a 96.0% success rate in 25 ICU patients with an average age of 69.46 y. Six-month follow-up studies revealed no significant differences in long-term complications between the ultrasound- and X-ray-guided groups. IVCFs may be safely implanted under ultrasound guidance in a monitored ICU environment. Our conclusion is that patients should be fasting and should receive an enema and that pre-operative surface marking and dynamic monitoring should be employed. Further research is needed to develop specific ultrasound guidelines.

The Ventilated Patient's Experience.

Critically ill intensive care unit (ICU) patients often experience pain, anxiety, panic, fear, dyspnea, and distress related to mechanical ventilation. Patients' recollections vary from having little or no memory of actual events to having total recall. Few studies have examined family members' memories and congruence with patients' symptom report and nurse observation. To describe the experience of the mechanically ventilated ICU patient. (1) to explore patient and family memories of pain, anxiety, distress, and dyspnea following mechanical ventilation; (2) to determine if there is a correlation among nurse-documented pain assessment and patient- and family-reported pain intensity; and (3) to determine the level of patient and family satisfaction with care while on the ventilator. This was a descriptive study design. A convenience sample of ICU patients (n = 84) and family members (n = 77) was interviewed. Medical record data abstraction included patient demographics, medication administration, and nurse assessment of pain and sedation. Most patient and family members reported memories of pain, anxiety/panic, nightmares or distress, and trouble breathing. Patients' perception of anxiety, nightmares, and dyspnea were moderately correlated with their pain perception (P = .000). Family members' memories of pain were correlated with nurse pain assessment behavioral scale ratings, but patients' memories of pain were not. Patients and family reported high satisfaction scores. Further inquiry of the patient's experience with mechanical ventilation, the use of a ventilation sedation management protocol, and the evaluation of effective communication tools such as the use of bedside reporting or patient communication boards is warranted.
