Purpose: Patients with hematologic malignancy (HM) typically have a high mortality rate when their condition deteriorates. The chronic progressive course of the disease makes it difficult to assess the effect of intervention on acute events. We investigated the effectiveness of a rapid response team (RRT) on in-hospital mortality in patients with HM. Methods: We retrospectively analyzed the data of patients with HM who admitted to the medical intensive care unit between 2006 and 2015. Clinical outcomes before and after RRT implementation were evaluated. Results: A total of 228 patients in the pre-RRT period and 781 patients in the post-RRT period were included. The overall in-hospital mortality was 55.4%. Patients in the post-RRT period had improved survival; however, they required more vasopressor therapy, continuous renal replacement therapy, and extracorporeal membrane oxygenation. Multivariate analysis revealed that in-hospital mortality was associated with RRT activation (hazard ratio [HR], 0.634; 95% confidence interval [CI], 0.498-0.807; p < .001), neurological disease (HR, 2.007; 95% CI, 1.439-2.800; p < .001), sequential organ failure assessment score (HR, 1.085; 95% CI, 1.057-1.112; p < .001), need for continuous renal replacement therapy (HR, 1.608; 95% CI, 1.206-1.895; p< .001), mechanical ventilation (HR, 1.512; 95% CI, 1.206-1.895; p< .001), vasopressor (HR, 1.598; 95% CI, 1.105-2.311; p = .013), and extracorporeal membrane oxygenation (HR, 1.728; 95% CI, 1.105-2.311; p = .030). Conclusion: RRT activation may be associated with improved survival in patients with HM.
Background: This study investigated mortality and morbidity in patients requiring postcardiotomy extracorporeal membrane oxygenation (ECMO) support after operations for congenital heart disease (CHD). Methods: CHD patients requiring postoperative ECMO support between May 2011 and May 2021 were retrospectively reviewed. Patients were divided into non-survivors and survivors to hospital discharge. Survival outcomes and associations of various factors with in-hospital death were analyzed. Results: Fifty patients required postoperative ECMO support. Patients' median age and weight at the time of ECMO insertion were 1.85 months (interquartile range [IQR], 0.23-14.5 months) and 3.84 kg (IQR, 3.08-7.88 kg), respectively. Twenty-nine patients (58%) were male. The median duration of ECMO support was 6 days (IQR, 3-12 days). Twenty-nine patients (58%) died on ECMO support or after ECMO weaning, and 21 (42%) survived to hospital discharge. Postoperative complications included renal failure (n=33, 66%), bleeding (n=11, 22%), and sepsis (n=15, 30%). Prolonged ECMO support (p=0.017), renal failure (p=0.005), continuous renal replacement therapy (CRRT) application (p=0.001), sepsis (p=0.012), bleeding (p=0.032), and high serum lactate (p=0.002) and total bilirubin (p=0.017) levels during ECMO support were associated with higher mortality risk in a univariate analysis. A multivariable analysis identified CRRT application (p=0.013) and a high serum total bilirubin level (p=0.001) as independent risk factors for death. Conclusion: Postcardiotomy ECMO should be considered as an important therapeutic modality for patients unresponsive to conventional management. ECMO implementation strategies and management in appropriate patients without severe complications, particularly renal failure and/or liver failure, are crucial for achieving positive outcomes.
Purpose: This study aimed to investigate the clinical alarm occurrence and management of nurses toward clinical alarms in the intensive care unit (ICU). Methods: This observational study was conducted with 40 patients and nurses cases in two ICUs of a university hospital. This study divided 24 hours into the unit of an hour and conducted two times of direct observation per unit hour for 48 hours targeting the medical devices applied to 40 patients. Data were analyzed using IBM SPSS Statistics 23. Results: On average, 3.8 units of medical devices were applied for each patient and the ranges of alarm settings were wide. During 48 hours, 184 cases of clinical alarm were occurred by four types of medical devices including physiological monitors, mechanical ventilators, infusion pumps, and continuous renal replacement therapy. Among them, false alarm was 110 cases (59.8%). As for the alarm management by ICU nurses, two-minute alarm mute took up most at 38.0% (70 cases), and no response was second most at 32.6% (60 cases). When valid alarm sounded, nurses showed no response at 43.2%. Conclusion: The findings suggest that a standard protocol for alarm management should be developed for Korean ICU settings. Based on the protocol, continuous training and education should be provided to nurses for appropriate alarm management.
Purpose: This study was designed to investigate whether nutritional supply influences biochemical markers and clinical outcomes in patients who received continuous renal replacement therapy (CRRT) by evaluating adequacy of nutritional supply for patients. Methods: From January 2012 to December 2013, 239 adult patients who received CRRT in the intensive care unit for more than 3 days were included. General information from electronic medical records and nutritional status related biochemical data and clinical outcomes on the first day of CRRT and 2 weeks after CRRT were collected. Results: The rate of delivered energy and protein was 68.06% and 43.13% which was much lower than energy and protein supply based on their requirement. When the patients were divided into two groups according to 70% of energy received rate and 50% of protein received rate, the group with more than 70% of energy received rate showed significant decrease of length of hospital stay (p = 0.007), length of stay in intensive care unit (ICU) (p = 0.008), duration of CRRT (p < 0.001), and APACHE II score (p < 0.001) compared to less than 70% of energy received rate after adjusting for age. In addition, the group with more than 50% of protein received rate showed decreased mortality (p = 0.031), length of hospital stay (p = 0.008), length of ICU stay (p = 0.035), duration of CRRT (p < 0.001), and APACHE II score (p < 0.001) after adjusting for age. We found that the level of hematocrit (p = 0.006) was significantly improved in the group with more than 70% of energy received rate, and the level of TLC (p = 0.049), hematocrit (p = 0.041) was significantly improved in the group with more than 50% of protein received rate. We also found that energy delivery was negatively correlated with length of stay in ICU (p = 0.049) and positively correlated with level of calcium (p = 0.037). In addition, protein delivery was correlated with the levels of serum total protein (p = 0.021), serum albumin (p = 0.048), hematocrit (p = 0.009), and total cholesterol (p = 0.021) when dead patients were included, but was correlated with the levels of hematocrit (p = 0.034) and calcium (p = 0.024) when dead patients were excluded. Conclusion: Proper nutritional delivery may help patients' clinical outcomes for patients receiving CRRT. However, their actual intakes of energy and protein were not adequate for their requirements. Identification of patients with malnutrition is necessary and a multidisciplinary approach for systemic management is also required.
Purpose : Regional anticoagulation with trisodium citrate for continuous renal replacement therapy(CRRT) is an effective and safe method, with lower bleeding risk. However it is not widely used because of complex current protocols used to prevent anticipated metabolic derangements. We evaluated simplified regional anticoagulation protocols with ACD-A(R) solution and commercially available calcium-containing dialysis solution. Methods : The medical records of twenty-eight patients who underwent CRRT were reviewed. Hemofilter life span according to the anticoagulation method used was compared, and laboratory findings at Pre- and 48 hours post-CRRT initiation were compared in the citrate-based CRRT group. Results : Of the twenty-eight Patients, five patients underwent citrate-based CRRT Hemofilter life span was 1.60 $\pm$ 0.72 days, showing no significant differences with the hemofilter life span in the heparin based and LMWH based CRRT group. No patients experienced hemorrhagic complications. PT, aPTT, sodium, t$CO_{2}$, iCa levels showed no difference in pre- and post-CRRT. Total calcium levels were increased. At the recommended postfilter iCa level, j.e., 0.25-0.39 mmol/L, all five patients needed increased amount of citrate infusion, and Ca infusion requirement was decreased. Conclusion : Simplified regional citrate anticoagulation with calcium-containing dialysate is an effective and safe method, and is not associated with increased hemofilter clotting. However, increased postfilter iCa level is recommended.
Purpose: The time lag between the decision to initiate continuous renal replacement therapy (CRRT) and its actual initiation remains a major barrier in our intensive care units. We developed a CRRT pop-up chart on EMR for managing CRRT machines. Methods: This study measured time interval between the decision to prepare the CRRT machine and the actual use of the machine before and after using a CRRT pop-up chart. This study conducted a questionnaire of the medical staff to assess the changes in the quality of CRRT preparation. Results: A total of 95 patients on CRRT is analyzed. The time to find an available CRRT machine is decreased by 24.6%. The time to move a CRRT machine to the patient's bedside is decreased by 55.8%. Medical surveys of 44 nurses gave the following results. 1) The time to apprehend machines for 1 to 3 minutes is improved from 29.5% to 81.8%, and the time to apprehend machines over 3 minutes is decreased from 70.5% to 18.2%. 2) The number (6-all) of known machine locations is improved from 22.7% to 63.4%. 3) Interruption of a nurse's work due to telephone calls asking for the possession of movable CRRT equipment also is improved. Scores of 1-4 are improved from 15.9% to 41%. Scores of 5-7 are reduced from 52% to 15.9%. Conclusions: CRRT pop-up chart is shortened the time lag of CRRT machine preparation, reduced the nurse's phone workload and helped to improve the quality of CRRT care.
Objective: The objective of this study was to compare the quality of life (QOL) of patients with end-stage renal disease (ESRD) between patients receiving hemodialysis (HD) and patients receiving continuous ambulatory peritoneal dialysis (CAPD) and to compare personal characteristic factors relating to the quality of life in patients with ESRD. Method: This study used a descriptive research design. The sample was recruited using purposive sampling that included 76 ESRD patients receiving either HD or CAPD at a dialysis clinic in Phraphutthabat Hospital, Saraburi Province, Thailand. Data was collected using the Quality of Life Questionnaire for Chronic Kidney Disease ($KDQOL-SF^{TM}$) version 1.3. Independent t-test and ANOVA procedures were used to analyze study data. Results: The results revealed that the HD patients had a moderate level of QOL. The highest scoring dimension of QOL was the encouragement of staff at the dialysis unit and patient satisfaction with the treatment (${\bar{X}}=100$, SD=.00), followed by social support (${\bar{X}}=89.29$, SD =16.88) and cognitive function (${\bar{X}}=88.57$, SD=11.82). On the other hand, the lowest scoring QOL dimension was physical problems (${\bar{X}}=50$, SD=51.89), and pain (${\bar{X}}=50$, SD=39.03), followed by work status (${\bar{X}}=53.57$, SD=45.84) and burden from kidney disease (${\bar{X}}=58.48$, SD=31.07). The CAPD patients also had a moderate QOL. The highest scoring QOL dimension was the encouragement of staff in the renal unit and patient satisfaction with the treatment (${\bar{X}}=100$, SD=.00), followed by social support (${\bar{X}}=95.61$, SD=14.20) and cognitive function (${\bar{X}}=88.83$, SD=13.52). The worst scoring QOL dimensions were work status (${\bar{X}}=44.44$, SD=42.72), general health (${\bar{X}}=53.61$, SD=39.05), and pain (${\bar{X}}=62.70$, SD=41.14). The difference overall and in each dimension of QOL in ESRD patients who were treated with HD and CAPD was not statistically significantly different. The QOL was not significantly different among patients with different personal characteristics except for income and duration of treatment; in those cases, the difference in QOL was statistically significant (p=.05). Conclusion: The overall QOL and life expectancy of patients with ESRD treated with HD and CAPD are not affected by gender, age, marital status, education, occupation, or type of health coverage. QOL was not significantly different, except for patients with different incomes and duration of renal replacement therapy, whose QOL was significantly different. The QOL of patients receiving dialysis should be studied to develop a QOL program for patients with chronic kidney disease who receive dialysis.
Purpose: This study was conducted to identify changes in limb circumferences among patients admitted to the intensive care unit (ICU) and related factors. Methods: We conducted a prospective observational study with 27 patients from 3 ICUs at a university hospital located in B city of Korea, from September 1 to October 30, 2015. The circumferences of the left and right upper arms, thighs, and lower legs were measured on the first, third, fifth, and seventh days of ICU admission. Information on the related factors was collected from the medical records. The data were analyzed using a linear mixed model method. Results: The limbs circumferences significantly reduced from day 3, and the changes continued till day 7. These changes were related to the gender of the subjects, restraints application, use of steroids, and continuous renal replacement therapy. Conclusions: Based on the above results, it can be concluded that ICU-acquired weakness begins before the third day of admission. Thus, early mobilization protocols for ICU patients need to be developed and implemented in order to improve long-term outcomes.
A 61-year-old female patient was diagnosed with dilated cardiomyopathy with severe left ventricle dysfunction. Two days after admission, continuous renal replacement therapy was performed due to oliguria and lactic acidosis. On the fifth day, an intra-aortic balloon pump was inserted due to low cardiac output syndrome. Beginning 4 days after admission, she was supported for 15 days thereafter with an extracorporeal left ventricular assist device (LVAD) because of heart failure with multi-organ failure. A heart transplant was performed while the patient was stabilized with the LVAD. She developed several complications after the surgery, such as cytomegalovirus pneumonia, pulmonary tuberculosis, wound dehiscence, and H1N1 infection. On postoperative day 19, she was discharged from the hospital with close follow-up and treatment for infection. She received follow-up care for 10 months without any immune rejection reaction.

Drug abuse and its related problems are increasing continuously in Korea. One of the most frequently abused drugs is methamphetamine, but there are few medical report in Korea. This is the first report of the identification of methamphetamine in the blood of a patient who had a return of spontaneous circulation after cardiac arrest and survived discharge. A 33-year-old male arrived at the emergency department presenting with chest pain and dyspnea. He had ingested methamphetamine and alcohol approximately 7 hours before arrival. One hour after arrival, he had seizure followed by cardiac arrest. Spontaneous circulation was recovered after 4 minutes of CPR. An analysis of the National Forensic Service identified plasma methamphetamine with an estimated average concentration of plasma methamphetamine at the time of arrival of 0.6 mg/L, a lethal dose. He had rhabdomyolysis and acute kidney injury but survived after continuous renal replacement therapy. Since then, he has suffered chronic kidney disease, and he is being followed up at the out-patient department. In Korea, although drug abuse is still uncommon, it is on the increase. Therefore, emergency physicians should be aware of the clinical characteristics of methamphetamine poisoning.
