Background A recently released dopamine-1 receptor agonist, fenoldopam, increases intraocular pressure (IOP) in both healthy volunteers and patients with chronic ocular hypertension. Dopamine, a potent agonist at both dopamine-1 and -2 receptors, is frequently infused in critically ill patients for its inotropic, renal vasodilatory, and natriuretic effects. The authors hypothesized that low doses of dopamine would significantly increase IOP. Methods Patients in the intensive care unit who were currently receiving dopamine infusions of less than 5 microg x kg(-1) x min(-1) were studied After local ocular anesthesia was obtained, baseline IOP was measured in each eye with a hand-held tonometer. IOP was then determined after dopamine was discontinued. Results Twenty-three patients received a mean dopamine infusion of 2.6 +/- 0.2 microg x kg(-1) x min(-1). Twelve of the 23 patients were receiving mechanical ventilation during the study. Mean IOPs in nonventilated patients (n = 11) off dopamine were 13.1 +/- 0.9 mmHg (left eye) and 12.6 +/- 0.9 mmHg (right eye). Mean IOPs for the same patients receiving dopamine were significantly higher at 16.1 +/- 0.9 mmHg (left eye) and 15.9 +/- 1.1 mmHg (right eye). Mean IOPs in intubated patients (n = 12) off dopamine were 12.3 +/- 0.7 mmHg (left eye) and 12.5 +/- 1.2 mmHg (right eye). Mean IOPs for the same patients while receiving dopamine were significantly higher in intubated patients at 17.8 +/- 1.3 mmHg (left eye) and 17.3 +/- 1.3 mmHg (right eye). The average mean elevation in IOP in patients while receiving dopamine was significantly higher in intubated patients as compared with nonintubated patients (5.2 +/- 0.9 mmHg vs. 3.1 +/- 0.6 mmHg). Conclusions Commonly used doses of dopamine are associated with increased IOP in critically ill patients. Although normal patients should be able to tolerate this elevation safely for several weeks, there may be a potential risk in patients with preexisting glaucomatous nerve damage or ocular hypertension, especially if they are sedated and mechanically ventilated.

Critically ill patients often require multiple organ supports; respiratory support in terms of mechanical ventilation (MV) is one of the commonest. But, only providing an organ support contributes less to the complete well being of the patients. Moreover, MV itself can affect various physiological systems, metabolic response, and cause side effects. A very close temporal relationship exists between patients, monitoring and management decision too, and therefore, appropriate information from monitoring can lead to better outcomes. The present review is intended to briefly highlight the current opinions and strategies for non cardio-respiratory monitoring in such critically ill patients.Abbreviations: AKI-Acute Kidney Injury; APACHE-Acute Physiology and Chronic Health Evaluation; BPS-Behavioral Pain Scale; CAM-ICU-Confusion Assessment Method for the Intensive Care Unit; CPOT–Critical Care Pain Observation Tool; EVLWI-Extra vascular lung water index; FDA-Food and Drug Administration; ISO-International Organization for Standardization; ICU-Intensive Care Unit; LOS-Length of stay; MODS-Multiple Organ Dysfunction Score; MV-Mechanical Ventilation; PaO2-Partial pressure of arterial oxygen; FiO2-Fraction of inspired oxygen; SAPS-Simplified Acute Physiologic Score; RASS-Richmond Agitation Sedation Scale; SOFA-Sequential Organ Failure Assessment; SAS-Sedation Agitation Scale; UO-Urine outputCitation: Panda CK, Karim HMR, Singha SK.

The Impact

Abstract Background SARS-CoV2 is a grave illness and few therapeutic agents have yielded benefit or reduced mortality. Administration of convalescent plasma (CP) in viral illnesses in the past, including SARS, before day 14, has been associated with a shorter hospital course. In the present study, we are interested in determining the benefit of administering CP to critically ill patients in the intensive care unit, and the impact on mortality and other clinical markers. Methods 5 critically ill patients with confirmed SARS-CoV2 infection were observed in the uncontrolled case series study. Mechanically ventilated patients with severe ARDS (PaO2/FiO2 < 100) were eligible to receive CP transfusion. We reviewed daily vital signs, inflammatory markers, PaO2/FiO2 ratio and SOFA scores before and after CP transfusions. SARS-CoV2 PCR viral load testing was completed on day 0 of transfusion and repeated on day 3 and 6. Complications during the hospitalization and 30-day mortality were assessed. Results All 5 patients were mechanically ventilated at the time of transfusion and between day 7 to 31 of their illness. Following plasma transfusion, body temperature and inflammatory markers remained elevated in four patients (figure 1). SOFA score and PaO2/FiO2 ratios continued to worsen in three and four patients respectively (figure 2). SARS-CoV2 PCR remained positive in 4 patients. 4 of the 5 patients had died at the end of the follow up period. One patient was successfully extubated on day 29 (table 1) and discharged after a long hospital course. Fever curve and trends of inflammatory markers Trends of SOFA socre and PaO2:FiO2 ratio Patient characteristics Conclusion In our patient cohort, the administration of CP did not improve laboratory markers or clinical outcomes. Some notable limitations of this study are the small sample size, and that the patients received CP late in their disease course. Further investigation is necessary to draw definitive conclusions about the utility of CP in the treatment of SARS-CoV2. Disclosures All Authors: No reported disclosures

Abstract Background Abolished circadian rhythm is associated with altered cognitive function, delirium, and as a result increased mortality in critically ill patients, especially in those who are mechanically ventilated. The causes are multifactorial, of which changes in circadian rhythmicity may play a role. Melatonin plays a crucial role as part of the circadian and sleep/wake cycle. Whether sedation effects circadian regulation is unknown. Hence, the objective of this study was to evaluate the melatonin concentration in critically ill patients randomized to sedation or non-sedation and to investigate the correlation with delirium. Methods All patients were included and randomized at the intensive care unit at the hospital of southwest Jutland, Denmark. Seventy-nine patients completed the study (41 sedated and 38 non-sedated). S-melatonin was measured 3 times per day, (03.00, 14.00, and 22.00), for 4 consecutive days in total, starting on the second day upon randomization/intubation. The study was conducted as a sub-study to the NON-SEDA study in which one hundred consecutive patients were randomized to sedation or non-sedation with a daily wake-up call (50 in each arm). Primary outcome: melatonin concentration in sedated vs. non-sedated patients (analyzed using linear regression). Secondary outcome: risk of developing delirium or non-medically induced (NMI) coma in sedated vs. non-sedated patients, assessed by CAM-ICU (Confusion Assessment Method for the Intensive Care Unit) analyzed using logistic regression. Results Melatonin concentration was suppressed in sedated patients compared to the non-sedated. All patients experienced an elevated peak melatonin level early on in the course of their critical illness (p = 0.01). The risk of delirium or coma (NMI) was significantly lower in the non-sedated group (OR 0.42 CI 0.27; 0.66 p < 0.0001). No significant relationship between delirium development and suppressed melatonin concentration was established in this study (OR 1.004 p = 0.29 95% CI 0.997; 1.010). Conclusion Melatonin concentration was suppressed in sedated, critically ill patients, when compared to non-sedated controls and the frequency of delirium was elevated in sedated patients.

*** Evaluation of pain levels of critically ill intensive care unit patients, before, during and after a session of chest physical therapy: a pilot study ***AIMS: To evaluate pain levels of critically ill patients before, during, and after a chest physical therapy intervention.METHODS: Pilot study conducted at the intensive care unit (ICU) of a teaching hospital. Sedated and mechanically ventilated adult patients aged 18 to 60 years were selected. Sociodemographic, clinical, and hemodynamic data were analyzed, and the Behavioral Pain Scale (BPS) scale was used to assess pain in patients unable to be evaluated by self-report questionnaires.The physical therapy protocol consisted of  manual vibrocompression maneuvers in both hemithoraces and of intratracheal aspiration. The hemodynamic variables and the BPS were analyzed in three periods: immediately before, in the fifth minute of intervention, and immediately after physical therapy. The Shapiro-Wilk test and ANOVA were used for the statistical analyses. The level of significance was p ≤0.05.RESULTS: The sample consisted of 22 patients, most of them male, aged 55±23.8 years. Nosocomial pneumonia the most prevalent pathology. There were no significant differences in hemodynamic variables and in pain assessment (p = 0.78) of the critically ill patients in any of the evaluated periods.CONCLUSIONS: In this sample of critically ill and mechanically ventilated ICU patients , no alterations in pain levels were detected during or after chest physical therapy.
