Background: There is lack of evidence regarding nutritional management among intensive care unit (ICU) patients in a population with relatively low body mass index. Therefore, we conducted an observational study to assess the nutritional management in Japanese ICUs. Also, we investigated the impact of nutritional management and rehabilitation on physical outcome. Methods: The study population comprised 389 consecutive patients who received mechanical ventilation for at least 24 h and those admitted to the ICU for > 72 h in 13 hospitals. The primary outcomes were caloric and protein intake in ICU on days 3 and 7, and at ICU discharge. The secondary outcome was the impact of nutritional management and rehabilitation on physical status at ICU discharge. We defined good physical status as more than end sitting and poor physical status as bed rest and sitting. We divided the participants into 2 groups, namely, the good physical status group (Good group) and poor physical status group (Poor group) for analysis of the secondary outcome. Data were expressed as median (interquartile range). Results: The median amount of caloric intake on days 3 and 7, and at ICU discharge via enteral and parenteral routes were 8.4 (3.1–15.6), 14.9 (7.5–22.0), and 11.2 (2.5–19.1) kcal/kg/day, respectively. The median amount of protein intake on days 3 and 7, and at ICU discharge were 0.2 (0–0.5), 0.4 (0.1–0.8), and 0.3 (0–0.7) g/kg/day, respectively. The amount of caloric intake on day 3 in the Poor group was significantly higher than that of the Good group (10.1 [5.8, 16.2] vs. 5.2 [1.9, 12.4] kcal/kg/day, p < 0.001). The proportion of patients who were received rehabilitation in ICU in the Good group was significantly higher than that of the Poor group (92 vs. 63%, p < 0.001). The multivariate analysis revealed that caloric intake on day 3 and rehabilitation in ICU were considered independent factors that affect physical status (OR 1.19; 95% CI 1.05–1.34; p = 0.005 and OR 0.07; 95% CI 0.01–0.34; p = 0.001). Conclusions: The caloric and protein intakes in Japanese ICUs were 15 kcal/kg/day and 0.4 g/kg/day, respectively. In addition, critically ill patients might benefit from low caloric intake (less than 10 kcal/kg/day) until day 3 and rehabilitation during ICU stay.
CaseWe report a lethal case of a mamushi (Gloydius blomhoffii) bite. An 84‐year‐old woman was bitten by a mamushi snake on her right elbow. She was initially treated at another hospital, however, because the swelling expanded and her renal function worsened, she was transferred to our hospital. Compartment syndrome, thrombocytopenia, respiratory arrest, and elevated creatinine kinase and lactose dehydrogenase levels were seen; renal failure progressed, and ileus and peritonitis due to colon perforation occurred.OutcomeThe patient died 35 days after the bite. An autopsy revealed widespread necrosis of the ileum, colon, and liver.ConclusionThis report supplies useful clinical information on the treatment of severe mamushi bite cases, and severe abdominal symptoms, such as ileus and melena, may be a lethal sign.
The discussion of neurocritical care management in post-cardiac arrest syndrome (PCAS) has generally focused on target values used for targeted temperature management (TTM). There has been less attention paid to target values for systemic and cerebral parameters to minimize secondary brain damage in PCAS. And the neurologic indications for TTM to produce a favorable neurologic outcome remain to be determined. Critical care management of PCAS patients is fundamental and essential for both cardiologists and general intensivists to improve neurologic outcome, because definitive therapy of PCAS includes both special management of the cause of cardiac arrest, such as coronary intervention to ischemic heart disease, and intensive management of the results of cardiac arrest, such as ventilation strategies to avoid brain ischemia. We reviewed the literature and the latest research about the following issues and propose practical care recommendations. Issues are (1) prediction of TTM candidate on admission, (2) cerebral blood flow and metabolism and target value of them, (3) seizure management using continuous electroencephalography, (4) target value of hemodynamic stabilization and its method, (5) management and analysis of respiration, (6) sedation and its monitoring, (7) shivering control and its monitoring, and (8) glucose management. We hope to establish standards of neurocritical care to optimize brain function and produce a favorable neurologic outcome.
A: The distribution of antiserum injection time. The antiserum injection is quite delayed in the severe cases. B: An ROC curve. Fourteen h is a favorable cut‐off for the antiserum injection timing that distinguishes non‐severe and severe cases. C: The relationship between the antiserum injection timing and the final grades. The final grade increased as the antiserum injection timing was delayed.
Continuous hemodiafiltration using a hemofilter made from a membrane with cytokine adsorption properties is thought to be effective to remove cytokines in septic patients. In order to enhance cytokine removal capacity by increasing adsorption area, we devised a double polymethyl methacrylate continuous hemodiafiltration method, which involves serial connection of two polymethyl methacrylate membrane hemofilters, and we report clinical efficacy with this method. Of 74 patients who underwent continuous hemodiafiltration and had interleukin-6 blood levels measured during their ICU stay between March 2010 and June 2012, 13 patients with hypercytokinemia (interleukin-6 blood level >900 pg/mL) underwent series double continuous hemodiafiltration to be treated for hypercytokinemia. Cytokine reduction rate and clinical efficacy were compared between those 13 patients and those with a similar pathological condition who underwent continuous hemodiafiltration using the single polymethyl methacrylate membrane hemofilter. Interleukin-6 blood levels 6 h after continuous hemodiafiltration initiation increased in the single continuous hemodiafiltration group from 17040 ± 33660 pg/mL to 26290 ± 66250 pg/mL; however, interleukin-6 blood level significantly decreased in the series double continuous hemodiafiltration group from 20220 ± 29120 pg/mL to 6790 ± 10820 pg/mL. Interleukin-6 reduction rate during the period between initiation and 6 h after initiation of continuous hemodiafiltration was significantly higher in the series double continuous hemodiafiltration group(63.5 ± 38.9%) compared to that of the single continuous hemodiafiltration group (-342 ± 1306%)(P = 0.039). Series double continuous hemodiafiltration using two polymethyl methacrylate hemofilters with cytokine adsorbing capacity is effective to remove cytokine in hypercytokinemic septic patients.
A 61-year-old woman was admitted to our hospital with a fever, nausea, diarrhea, and back pain. Her condition rapidly deteriorated, and she was transferred to the intensive-care unit for mechanical circulatory support and antibiotics, but she died 40 h after admission. Autopsy findings showed necrotic and suppurative myocardial changes due to group B Streptococcus (GBS). To date, only one case of bacterial myocarditis caused by GBS has been reported. We herein report a case of GBS myocarditis, the etiology of which is poorly understood due to the limited number of cases. Bacterial myocarditis should be considered in patients with sepsis and myocardial dysfunction.
Aim It remains unclear how autonomic regulation modulates pathophysiological changes of sepsis. This study aims to analyze and clarify those in patients with suspected sepsis. Methods In this single‐centered, prospective, observational study, adult patients who had an infection, a quick Sequential Organ Failure Assessment score of 2 or more at the emergency department, and underwent intensive care were screened. Heart rate variability (HRV) and serum adrenaline were measured immediately after arrival. The primary outcome was defined as vasopressor dependence during 48 h after arrival. Results A total of 63 patients were included. All the patients had SOFA score of 2 or more on admission. Vasopressor dependence, renal replacement therapy, and in‐hospital mortality were associated with higher adrenaline (which reflects sympathetic adrenergic system activity). Bacteremia was associated with lower high‐frequency components of HRV (parasympathetic nerve activity). The HRV parameter of sympathetic nerve activity had no significant association with the outcomes. In the multivariate logistic regression model adjusted for age and sex, vasopressor dependence remained associated with higher adrenaline (cut‐off 0.11 ng/mL, odds ratio 9.71, 95% confidence interval 2.55–37; P = 0.000874), and lower high‐frequency components with bacteremia (17.2 ms 2 , odds ratio 4.86, 95% confidence interval 1.36–17.4; P = 0.0152). There were no significant correlations between parameters of HRV and serum adrenaline. Conclusion Hypoperfusion, organ dysfunction, and in‐hospital mortality were associated with an increased sympathetic adrenergic activity. Bacteremia was associated with decreased parasympathetic nerve activity. The autonomic regulator may involve a multilayered and differentiated modulating process for sepsis.
