    (2023) Doganci, Melek; Zeyneloglu, Pinar; Kayhan, Zeynep; Ayhan, Ali; 37575800; IVV-1127-2023; C-3736-2018; AAJ-4623-2021
    BackgroundPostoperative acute kidney injury (AKI) is an important cause of mortality and morbidity among surgical patients. There is little information on the occurrence of AKI after operations for gynecologic malignancies. This study aimed to determine the incidence of AKI in patients who underwent surgery for gynecological malignancies and determine the risk factors in those who developed postoperative AKI. MethodologyA total of 1,000 patients were enrolled retrospectively from January 2007 to March 2013. AKI was defined according to the Kidney Disease Improving Global Outcomes 2012 Clinical Practice Guideline for Acute Kidney Injury. Perioperative variables of patients were collected from medical charts.ResultsThe incidence of postoperative AKI was 8.8%, with stage 1 occurring in 5.9%, stage 2 in 2.4%, and stage 3 in 0.5% of the patients. Patients who had AKI were significantly older, had higher body mass index (BMI) higher preoperative C-reactive protein (CRP) levels, and more frequently had a history of distant organ metastasis when compared with those who did not have AKI. When compared with patients who did not develop AKI postoperatively, longer operation times and intraoperative usage of higher amounts of erythrocyte suspension and fresh frozen plasma were seen in those who developed AKI. ConclusionsPatients who had AKI were older, had higher BMI with higher preoperative CRP levels, more frequent distant organ metastasis, longer operation times, and higher amounts of blood transfused intraoperatively. Defining preoperative, intraoperative, and postoperative risk factors for postoperative AKI and taking necessary precautions are important for the early detection and intervention of AKI.

    (2023) Atar, Funda; Sahinturk, Helin; Zeyneloglu, Pinar; Ozdemirkan, Aycan; 0000-0003-0159-4771; AAJ-1419-2021
    Objective: Left ventricular assist device surgery (LVAD) associated acute kidney injury (AKI) is a severe complication of cardiac surgery with 15-45% incidence. The study evaluated AKI in the early postoperative period after LVAD surgery using the Kidney Disease: Improving Global Outcomes (KDIGO) criteria and compare patients with and without AKI to determine the incidence, risk factors, and clinical outcomes. Materials and Methods: In this retrospective cohort study, the medical records of all patients aged between 18 and 75 years who underwent LVAD implantation from January 2011 to December 2016 were reviewed. Patients were divided into two groups based on the development of AKI to analyze demographic features and perioperative variables. AKI was defined according to the KDIGO criteria. Results: Out of 57 patients, 10 (18%) were female, and the cohort's mean age was 44.6 +/- 16.1 years. Thirty-six patients (63%) developed AKI following LVAD implantation. Logistic regression analysis revealed the duration of cardiopulmonary bypass (CPB), mean arterial pressure, and cumulative fluid balance on the first postoperative day as independent risk factors for AKI [odds ratio (OR): 1.013, confidence interval (CI) 95% 1.000-1.025, p=0.05; OR: 0.929, CI 95% 0.873-0.989, p=0.02; OR: 1.001, CI 95% 1.000-1.001, p=0.04 respectively]. Hospital mortality (58% vs. 24%, p=0.01) and 30-day mortality (39% vs. 5%, p=0.01) were significantly higher in patients who had AKI. Conclusion: Risk factors for the occurrence of AKI include a longer duration of CPB, lower mean arterial pressures, and higher cumulative fluid balance on the first postoperative day. Therefore, AKI is one of the most important causes of morbidity and mortality after LVAD.

    (2022) Yesiler, Fatma Irem; Akmatov, Nursultan; Nurumbetova, Oktom; Beyazpinar, Deniz Sarp; Sahinturk, Helin; Gedik, Ender; Zeyneloglu, Pinar; 0000-0003-0159-4771; 36540477; AAJ-1419-2021
    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.

    (2022) Yesiler, Fatma Irem; Yazar, Cagla; Ordu, Irem Ulutas; Sahinturk, Helin; Yalcin, Tugba Yanik; Zeyneloglu, Pinar; 0000-0003-0159-4771; 0000-0002-0612-8481; AAJ-1419-2021; AAJ-4212-2021
    Objective: Sepsis due to the drug resistant infections is associated with the higher mortality rates in an intensive care unit (ICU). The aim of this study was to determine the demographic characteristics of the deceased critically ill patients, prevalence of the sepsis, and extensively drug resistant infectious-related (XDR) deaths within a year in the ICU. Materials and Methods: The data of patients who died in the ICU between January 1, 2019 and 2020 was retrospectively analyzed. Results: Out of 525 patients admitted to the ICU, 269 of them died. One hundred fifty-one of those deceased patients (56.1%) were in medical and 118 (43.9%) in the surgical ICU. Their mean age was 70.5 +/- 15 years and 126 (46.8%) of them were female. The mean Acute Physiology and Chronic Health Evaluation-II, Glasgow coma score, Sequential Organ Failure Assessment scores at ICU admission were 23.4 +/- 20.9, 9.8 +/- 4.4, and 8.2 +/- 3.6, respectively. A few reasons for the ICU admission were: respiratory failure (34.9%), neurologic dysfunction (19%), sepsis (17.8%), and cardiovascular failure (16%). Infection occurred in the 231 (85.9%) patients. Of the 109 (40.5%) deceased patients with the diagnosis of sepsis, 48 (40%) of them were admitted in the ICU with sepsis. The most common site of infection was the respiratory system (34.6%). Septic shock was seen in 170 patients (63.2%) and renal replacement therapy was needed in 61 (22.7%) of them. XDR developed in 34.6% of the deceased patients and was more frequent among those with an antibiotic usage before the ICU admission (p=0.02). The mean length of stay at hospital before the ICU admission and length of the ICU stay were 22 +/- 25.8 and 10.1 +/- 12.7 days, respectively. The number of the deceased medical patients were significantly higher than the surgical patients (p=0.018). Conclusion: The deceased critically ill medical patients were higher than the surgical patients. A total of 40% of the deceased critically ill patients were diagnosed with a sepsis, and one third of them had XDR infection. XDR infections were more frequent among the patients with an antibiotic usage before the ICU admission.

    (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.

    (2022) Yazar, Cagla; Yesiler, Fatma Irem; Sahinturk, Helin; Araz, Coskun; Zeyneloglu, Pinar; 0000-0002-3887-0314; 0000-0002-0612-8481; 0000-0003-0159-4771; AAJ-4212-2021; AAJ-1419-2021
    Rib fracture due to blunt chest trauma is a painful condition with high morbidity and mortality and it is two times prevalent among the elderly compared to young people. If adequate an analgesic treatment is not administered, respiratory complications, need for mechanical ventilation, and length of stay in intensive care unit may increase. Erector spinal plane (ESP) block is a regional unaesthetic method that can provide effective analgesia in the unilateral thoracic region. In this study, we present ESP block, which is used successfully in pain management of a critically ill old patient with multiple rib fractures.

    A Comparison of Echocardiography and the Pressure Recording Analytical Method (PRAM) for Predicting Fluid Responsiveness after Passive Leg Raising
    (2021) Ozdemirkan, Aycan; Aitakhanoya, Manat; Gedik, Ender; Zeyneloglu, Pinar; Pirat, Arash; 0000-0002-7175-207X; ABI-2971-2020
    Objective: This study aims to assess the agreement between the cardiac index (CI) measured by pressure recording analytical method (PRAM) and transthoracic echocardiography (TTE) before and after the passive leg raise (PLR) maneuver. Methods: This is a prospective observational study in critically ill patients who were monitored with MostcareUp/PRAM (Vygon, Vytech, Padova, Italy). Cardiac index (CI) values and percent changes in CI values in response to PLR were recorded by TTE and PRAM. Results: Data of a total of 25 patients were collected. The median CI values that were calculated by TTE before and after PLR were 2.5 (1.2-4.7) L/min/m(2) and 2.9 (1.4-5.6) L/min/m(2), respectively. The median CI values that were calculated by PRAM before and after PLR were 2.5 (1.5-4.8) L/min/m(2) and 2.6 (1.7-5.7) L/min/m(2), respectively. There was significant correlations between the measured CI values both by TTE and PRAM before and after PLR (r=0.635, p=0.001 and r=0.610, p=0.001, respectively). The median percent changes in CI with TTE and PRAM were -0.13 (-0.7-0.4) and -0.11 (-0.5-0.5), respectively. Sixteen patients were determined as FR by TTE (64%) and 13 patients were determined as FR by PRAM (52%). The Kappa test showed moderate agreement between TTE and PRAM for predicting fluid responsiveness (k=0.595; p=0.002). The mean biases between the CI values measured by TTE and PRAM before and after PLR were 0.04 +/- 0.77 L/min/m(2) and 0.22 +/- 0.88 L/min/m(2), respectively. Conclusion: This study showed a significant correlation for CI values measured by both methods. For predicting fluid responsiveness there was agreement between the two methods after PLR.

    Post-operative Respiratory Distress Due to Laryngeal Granuloma and Subglottic Stenosis in a Patient Undergoing Open Heart Surgery
    (2021) Yazar, Cagla; Aitakhanova, Manat; Gulleroglu, Aykan; Firat, Aynur Camkiran; Zeyneloglu, Pinar; 0000-0002-3887-0314; 0000-0002-6091-9065; AAJ-4188-2021
    The cause of impairment in respiratory functions after open heart surgery is multifactorial. A 67-year-old female patient admitted to the intensive care unit (ICU) was intubated after mitral valve replacement and tricuspid annuloplasty. She was extubated on the first post-operative (post-op) day. On post-op day 5, the patient was re-admitted to the ICU due to respiratory distress and tachypnea. Non-invasive mechanical ventilation (NIMV) support and dobutamine 5 mcg/kg/min were started. Prior to diagnosis of septic shock, tazocin 3x4.5 grams was administered. The patient was intubated on the post-op day 6 because of the increase in respiratory distress. She was extubated on the post-op day 7, and NIMV commenced. On the 8th post-op day, she was consulted to the ear, nose and throat (ENT) department because of sore throat. Widespread mucosal aphthous lesions were observed in the uvula, soft and hard palate, mandible inner mucosa and alveolar process. Galactomannan was detected positive in bronchoalveolar lavage and treatment with fluconozole started. On post-op day 15, the patient was discharged. That same night, she was admitted to the ICU again due to sudden respiratory distress and was placed on NIMV support, but the patient whose respiratory distress increased and was unconscious was intubated. The next day, direct laryngoscopy was performed by the ENT department under operating room conditions, and a 3x4 cm polypoid lesion was removed from the vocal cord level. However, after 2 days, the patient was re-examined by direct laryngoscopy, necrotic crusts were removed under the cricoid cartilage posteriorly in the subglottic region. The patient recovered from post-op respiratory distress, was extubated on the 18th post-op day and his support with NIMV continued. The patient was discharged on the 33rd post-op day. Laryngeal granuloma and subglottic strictures should be considered in patients with post-op respiratory distress, no matter how short the intubation period is.
