    Objective: Open heart surgery (OHS) is frequently performed on elderly patients. We aimed to investigate the risk factors associated with prolonged intensive care unit (ICU) stay in elderly patients undergoing open heart surgery. Materials and Methods: Medical records of all patients > 75 years who underwent OHS (coronary artery bypass grafting (CABG) and/or heart valve surgery) between June 1, 2013, and December 31, 2020, were retrospectively analyzed. Those staying in the ICU longer than five days were determined as prolonged ICU stay. Patients were divided into two groups, according to ICU stay <5 days and >5 days. Results: Out of the 198 patients included in the study, 130 (65.7%) were male. Seventy patients (35.4%) had prolonged ICU stay. The mean age was higher in patients within the prolonged ICU stay group when compared to the other group (79.9 +/- 3.5 years vs.78.1 +/- 2.7 years, p<0.001). The patients who used statins and angiotensin-converting enzyme inhibitors (ACEi)/angiotensin receptor blockers (ARBs) in the preoperative period had a shorter ICU stay compared to those who did not (45% vs 31.4%, p=0.04; 57% vs 42.9%, p=0.03). The history of previous thoracic surgery (2.3% vs 10% p=0.03), emergency surgery (12.5% vs 24.5% p=0.04), and preoperative pacemaker usage (0.8% vs 7%, 1 p=0.01) were higher in the group of patients with prolonged ICU stay compared to the other group. Preoperative ejection fraction (EF)% (47.7 +/- 11.3 vs 51.1 +/- 8.8, p<0.001) and hemoglobin level (11.8 +/- 1.9 mg/dL vs 12.9 +/- 1.6, p<0.001) were lower in the group with prolonged ICU stay compared to the other group. Incidence of cardiac arrest (3.9% vs 15.7% p=0.006), presence of arrhythmia (16.4% vs 41.6%,p<0.001), frequency of pacemaker and intra-aortic balloon pump (IABP) usage (0 vs 10% p=0.002; 1.6% vs 8.6% p=0.02), and need for renal replacement therapy (3.1% vs 12.9%,p=0.02) were higher in the group with prolonged ICU stay compared to the other group. According to the logistic regression analysis; higher age (OR: 1.225, 95%CI 1.104-1.360, p<0.001), preoperative pacemaker usage (OR: 0.100, 95%CI 0.01-0.969, p<0.04), preoperative statin non-use (OR: 2.056, 95%CI 1.040-4.066, p<0.03) and preoperative low EF (OR: 0.947, 95%CI 0.915-0.981, p=0.002) were determined as independent risk factors for prolonged ICU stay. Conclusion: The incidence of prolonged ICU stay after OHS among patients >75 years was 35.4% in our cohort. Higher age, preoperative pacemaker usage, preoperative statin non-use, and low preoperative EF were associated with prolonged ICU stay.

    Hemolysis, Elevated Liver Enzymes and Low Platelet Syndrome: Outcomes for Patients Admitted to Intensive Care at A Tertiary Referral Hospital
    (2017) Gedik, Ender; Yucel, Neslihan; Sahin, Taylan; Koca, Erdinc; Colak, Yusuf Ziya; Togal, Turkan; https://orcid.org/0000-0002-7175-207X; https://orcid.org/0000-0001-5845-2614; 27599183; ABI-2971-2020; ABI-3412-2020
    Purpose: The aim was to assess outcomes for pregnancies in which hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome develops and the patient requires transfer for critical care. Materials and Methods: The cases of women with HELLP syndrome who delivered at our tertiary center or surrounding hospitals and were admitted to the intensive care between January 2007 and July 2012 were retrospectively analyzed. Results were compared for the surviving and non-surviving patients. Results: Among the 77 women with HELLP syndrome, maternal mortality rate was 14% and 24 (30%) of 81 fetuses and newborns died in the perinatal period. The most common maternal complications were disseminated intravascular coagulation (DIC) (n = 22; 29%), acute renal failure (n = 19; 25%), and postpartum hemorrhage (n = 16; 21%). Compared with surviving women, the non-surviving women had higher mean international normalized ratio (INR) (p < 0.0001); higher mean serum levels of aspartate aminotransferase (AST) (p < 0.0001); higher alanine aminotransferase (ALT) (p < 0.0001); higher lactate dehydrogenase (LDH) (p < 0.0001), and higher bilirubin (p = 0.040) levels; and lower platelet count (p = 0.005). Conclusion: DIC is a major risk factor for maternal outcome among patients with HELLP syndrome who require intensive care. Low platelet count; high AST, ALT, LDH, INR; and total bilirubin are associated with high mortality risk in this patient group. In addition, low platelet count; low fibrinogen level; prolonged activated thromboplastin time; high INR; and high total bilirubin, LDH, blood urea nitrogen, and creatinine are associated with high risk for complications in this patient group.

    Comparison Of Confirmed And Probable COVID-19 Patients In The Intensive Care Unit During The Normalization Period
    (2022) Yesiler, Fatma Irem; Capras, Mesher; Kandemir, Emre; Sahinturk, Helin; Gedik, Ender; Zeyneloglu, Pinar; https://orcid.org/0000-0002-0612-8481; https://orcid.org/0000-0003-0159-4771; 34812130; AAJ-4212-2021; AAJ-1419-2021
    The decrease in social distance together with the normalization period as of June 1, 2020, in our country caused an increase in the number of coronavirus disease 2019 (COVID-19) patients. Our aim was to compare the demographic features, clinical courses, and outcomes of confirmed and probable COVID-19 patients admitted to our intensive care unit (ICU) during the normalization period. Critically ill 128 COVID-19 patients between June 1, 2020, and December 2, 2020, were analyzed retrospectively. The mean age was 69.7 +/- 15.5 y (61.7% male). Sixty-one patients (47.7%) were confirmed. Dyspnea (75.0%) was the most common symptom and hypertension (71.1%) was the most common comorbidity. The mean Acute Physiology and Chronic Health Evaluation System (APACHE II) score; Glasgow Coma Score; Sequential Organ Failure Assessment scores on ICU admission were 17.4 +/- 8.2,12.3 +/- 3.9, and 5.9 +/- 3.4, respectively. One hundred and one patients (78.1%) received low-flow oxygen, 48 had high-flow oxygen therapy (37.5%), and 59 (46.1%) had invasive mechanical ventilation. Fifty-three patients (41.496) had vasopressor therapy and 30 (23.4%) patients had renal replacement therapy due to acute kidney injury (AKI). Confirmed patients were more tachypneic (p= 0.005) and more hypoxemic than probable patients (p < 0.001). Acute respiratory distress syndrome and AKI were more common in confirmed patients than probable (both p < 0.001). Confirmed patients had higher values of hemoglobin, C- reactive protein, fibrinogen, and D-dimer than probables (respectively, p = 0.028. 0.006, 0.000. and 0.019). The overall mortality was higher in confirmed patients (p = 0.209, 52.6% vs. 47.4%). Complications are more common among confirmed COVID-19 patients admitted to ICU. The mortality rate of confirmed COVID-19 patients admitted to the ICU was found to be higher than probable patients. Mortality of confirmed cases was higher than prediction of APACHE-II scoring system.

    A Pregnant Woman with Jaundice in the Intensive Care Unit
    (A Pregnant Woman with Jaundice in the Intensive Care Unit, 2020) Yesiler, Fatma Irem; Sahinturk, Helin; Gunakan, Emre; Gedik, Ender; Zeyneloglu, Pinar; 0000-0003-0159-4771; 0000-0001-8854-8190; AAJ-1419-2021
    Acute fatty liver of pregnancy (AFLP) is a life-threatening disorder characterized by maternal liver failure, and it occurs in the third trimester of pregnancy or postpartum period. The resultant effects include coagulopathy, electrolyte abnormalities, and the multiple organ dysfunction syndrome (MODS), which may require liver transplantation. Therefore, pregnant women having MODS should be managed in an intensive care unit (ICU) with multidisciplinary inputs to facilitate the appropriate supportive care. We present a successful case report of a pregnant women admitted to the ICU with jaundice and MODS without the need for liver transplantation and organ support therapies. A 20-year-old patient in her first pregnancy at 31 weeks gestation who presented with nausea, vomiting, and jaundice was admitted to our hospital. She was referred from a rural medical center (a center 608 kilometers away) to the ICU due to the possible diagnosis of acute liver failure requiring liver transplantation. Acute physiology and chronic health assessment score was 12, sepsis related organ failure score was 8, and Glasgow coma scale was 15 on ICU admission. AFLP was considered in the patient and an emergency delivery was performed by caesarean section. She recovered with intensive care support after pregnancy delivery without the need for liver transplantation. The patient was discharged from the ICU and hospital after 6 and 10 days, respectively. AFLP should be suspected in the differential diagnosis of a pregnant woman with jaundice and hyperbilirubinemia who is admitted to the ICU in the third trimester of pregnancy or postpartum period. Intensivist should not delay in the diagnosis of AFLP due to its morbid complications and high mortality. Early diagnosis, prompt pregnancy delivery, and intensive care support in the peripartum and postpartum periods may improve maternal and fetal outcomes
