Publication Open Access Reduction of nosocomial infections in the intensive care unit using an electronic hand hygiene compliance monitoring system(2021-12-01) GÜL, FETHİ; YAKUT, NURHAYAT; BİLGİLİ, BELİZ; KASAPOĞLU, UMUT SABRİ; ARSLANTAŞ, MUSTAFA KEMAL; KEPENEKLİ KADAYİFCİ, EDA; Akkoc G., Soysal A., GÜL F., KEPENEKLİ KADAYİFCİ E., Arslantas M. K., Yakut N., BİLGİLİ B., Demir S. O., Haliloglu M., Kasapoglu U. S., et al.Introduction: Healthcare-associated infection is an important cause of mortality and morbidity worldwide. Well-regulated infection control and hand hygiene are the most effective methods for preventing healthcare-associated infections. This study evaluated and compared conventional hand hygiene observation and an electronic hand-hygiene recording and reminder system for preventing healthcare-associated infections. Methodology: This pre-and post-intervention study, employed an electronic hand-hygiene recording and reminder system for preventing healthcare-associated infections at a tertiary referral center. Healthcare-associated infection surveillance was recorded in an anesthesia and reanimation intensive care unit from April 2016 to August 2016. Hand-hygiene compliance was observed by conventional observation and an electronic recording and reminder system in two consecutive 2-month periods. healthcare-associated infections were calculated as incidence rate ratios. Results: The rate of healthcare-associated infections in the electronic hand-hygiene recording and reminder system period was significantly decreased compared with that in the conventional hand-hygiene observation period (incidence rate ratio = 0.58; 95% confident interval = 0.33-0.98). Additionally, the rate of central line-associated bloodstream infections and the rate of ventilator-associated pneumonia were lower during the electronic hand hygiene recording and reminder system period (incidence rate ratio= 0.41; 95% confident interval = 0.11-1.30 and incidence rate ratio = 0.67; 95% confident interval = 0.30-1.45, respectively). Conclusions: After implementing the electronic hand hygiene recording and reminder system, we observed a significant decrease in healthcare-associated infections and invasive device-associated infections. These results were encouraging and suggested that electronic hand hygiene reminder and recording systems may reduce some types of healthcare-associated infections in healthcare settings.Publication Open Access Abdominal perfusion pressure is superior from intra-abdominal pressure to detect deterioration of renal perfusion in critically Ill patients(TURKISH ASSOC TRAUMA EMERGENCY SURGERY, 2019) GÜL, FETHİ; Gul, Fethi; Sayan, Ismet; Kasapoglu, Umut Sabri; Erol, Derya Ozer; Arslantas, Mustafa Kemal; Cinel, Ismail; Aykac, ZuhalBACKGROUND: Intra-abdominal hypertension (IAH) is a frequent cause of acute kidney injury (AKI) among critically ill patients who have risk factors. This study aimed to determine the relation between Abdominal Perfusion Pressure (APP) and AKI showed by the Doppler-based renal resistive index (RRI). METHODS: In this study, 38 patients older than 18 years old who received mechanical ventilation and had risk factors for the development of IAH were prospectively studied. All measurements and parameters were divided into two groups according to renal dysfunction (Group I: RRI <0.72 vs Group II: RRI >0.72). RESULTS: The mean IAPs were not significant between the groups, 11.5 +/- 6.9 mm Hg in Group I (n=35) and 13.5 +/- 5.8 in Group II (n=33), respectively. APPs were statistically higher in Group I (81.2 +/- 13.6) than Group II (66.4 +/- 9.5) (p<0.001). The AUC for the association between APP at RRI >0.72 was 0.802 (p<0.001), with the APP <= 72 mmHg having a sensitivity of the 76% (95% CI 58-89%) and a specificity of 71% (95% CI 54-85%). CONCLUSION: Our findings suggest that an APP with a threshold of <= 72 mmHg is associated with a significant increase in renal RRI, which may be predictive of worsening of renal perfusion.Publication Open Access EPIDURALS, INTRAOPERATIVE FLUID ADMINISTRATION, AND HYPOTENSION Reply(MOSBY-ELSEVIER, 2015-07) KARARMAZ, ALPER; Arslantas, Mustafa Kemal; Kararmaz, Alper; Batirel, Hasan FevziPublication Open Access Renal Resistive Index is Unsusceptible to Systemic Hemodynamics in Fluid Responsive Critically III Patients(GALENOS YAYINCILIK, 2019-11-12) BİLGİLİ, BELİZ; Gul, Fethi; Bilgili, Beliz; Arslantas, Mustafa Kemal; Ayhan, Secil Ozcan; Cinel, IsmailObjective: The primary goal of fluid resuscitation in critically ill patients is to improve oxygen delivery to ensure adequate organ perfusion. Little evidence is known about renal response to fluids in the acute phase, so renal monitoring after the fluid challenge is fundamental during critical care stay. This study aimed to evaluate changes in the renal resistive index (RRI) and to compare these changes with hemodynamic parameters after fluid challenge in fluid responsive critically ill patients. Materials and Methods: Thirty patients older than 18 years who underwent sedation and received mechanical ventilation were prospectively studied. Twenty patients were fluid responsive and were included in the study. An increase of cardiac output (CO) by 10% or more after PLR measured by ultrasonic CO monitor suspected fluid responsiveness. 500 mL of isotonic solution was administered intravenously for 30 minutes. CO measurements were performed at 0, 1 and 30 minutes. RRI and mean arterial pressure (MAP) were measured by Doppler ultrasonography at 0 and 30 minutes. Repeated measures ANOVA method was used for statistical analysis and p<0.05 was considered significant. Results: CO increased significantly after fluid challenge when compared to baseline (from 3.48 +/- 1.14 to 4.34 +/- 1.43 L/min, p<0.001). MAP increased significantly after fluid administration when compared to baseline (80 +/- 19 to 86 +/- 17, p=0.002). RRI did not significantly differ from baseline after fluid challenge (62 +/- 9 to 60 +/- 10, p=0.11). There was a negative correlation between RRI and MAP at baseline and after fluid challenge. Conclusion: The effect of hemodynamic changes on renal perfusion after fluid challenge is controversial. In our study, 500 mL of crystalloid treatment for 30 minutes increased MAP and CO, but did not contribute to the improvement of RRI in patients who were fluid responsive. We found that fluid challenge did not improve RRI in the early phase of the fluid resuscitation in fluid responsive critically ill patients and RRI is unsusceptible to systemic hemodynamic changes during this period.Publication Open Access Sequential Measurements of Pentraxin 3 Serum Levels in Patients with Ventilator-Associated Pneumonia: A Nested Case-Control Study(HINDAWI LTD, 2018) BİLGİLİ, BELİZ; Bilgin, Huseyin; Haliloglu, Murat; Yaman, Ali; Ay, Pinar; Bilgili, Beliz; Arslantas, Mustafa Kemal; Ozdemir, Filiz Ture; Haklar, Goncagul; Cinel, Ismail; Mulazimoglu, LutfiyePurpose. The main purpose of this study was to investigate the dynamics of pentraxin 3 (PTX3) compared with procalcitonin (PCT) and C-reactive protein (CRP) in patients with suspicion of ventilator-associated pneumonia (VAP). Materials and Methods. We designed a nested case-control study. This study was performed in the Surgical Intensive Care Unit of a tertiary care academic university and teaching hospital. Ninety-one adults who were mechanically ventilated for >48 hours were enrolled in the study. VAP diagnosis was established among 28 patients following the 2005 ATS/IDSA guidelines. Results. The median PTX3 plasma level was 2.66 ng/mL in VAP adults compared to 0.25 ng/mL in non-VAP adults (p < 0.05). Procalcitonin and CRP levels did not significantly differ. Pentraxin 3, with a 2.56 ng/mL breakpoint, had 85% sensitivity, 86% specificity, 75% positive predictive value, and 92.9% negative predictive value for VAP diagnosis (AUC = 0.78). Conclusions. With the suspicion of VAP, a pentraxin 3 plasma breakpoint of 2.56 ng/mL could contribute to the decision of whether to start antibiotics.Publication Metadata only Renal Resistive Index Measurement by Transesophageal Echocardiography: Comparison With Trans lumbar Ultrasonography and Relation to Acute Kidney Injury(W B SAUNDERS CO-ELSEVIER INC, 2015) KARARMAZ, ALPER; Kararmaz, Alper; Arslantas, Mustafa Kemal; Cinel, IsmailObjectives: The aim of this study was to evaluate the relationship between transesophageal ultrasonography-derived renal resistive index values (RRITEE) and a standard translumbar renal ultrasound-derived RRI (RRITLUSG). The effectiveness of each method to predict acute kidney injury (AKI) after cardiac surgery also was compared. Design: A prospective observational study. Setting: A teaching university hospital. Participants: Sixty patients undergoing cardiac surgery. Interventions: First, RRI was measured with both methods after anesthesia induction. Second, another measurement was performed with TEE after cardiopulmonary bypass and immediately following the surgery with translumbar ultrasound. To test the correlation between the 2 methods and to plot a Bland-Altman graph, preoperative RRI values measured by both techniques were used. Receiver operating characteristic curves also were plotted to compare the diagnostic values of RRI measured intraoperatively by TEE after cardiopulmonary bypass and by RRITLUSG after surgery. Measurements and Main Results: There was a statistically significant correlation between the 2 RRI measurement approaches (r = 0.86, p < 0.0001). The Bland-Altman plot indicated good agreement between the methods. The area under the curve (AUC) of RRITEE in predicting AKI was 0.82 (95% confidence interval (Cl] = 0.64-0.9, p = 0.001), and the AUC of RRITLUSG after surgery was 0.85 (95% Cl = 0.7-0.98, p < 0.0001). In predicting AKI, an uncertainty zone for RRITEE values between 0.68 and 0.71 was computed by the gray-zone approach. Conclusions: RRITEE showed clinically acceptable agreement with RRITLUSG. Indeed, RRI measured intraoperatively with TEE was comparable to RRITLUSG in terms of detecting postoperative AKI. (C) 2015 Elsevier Inc.

A national, multicenter, point-prevalence study was conducted to determine the prevalence, causative microorganisms, and outcome of sepsis in intensive care units (ICUs) in Turkey. Methods: A total of 132 ICUs from 94 hospitals participated. All patients (aged > 18 years) present at the participating ICUs or admitted for any duration within a 24-h period (08:00 on January 27, 2016 to 08:00 on January 28, 2016) were included. The presence of systemic inflammatory response syndrome (SIRS), severe sepsis, and septic shock were assessed and documented based on the consensus criteria of the American College of Chest Physicians and Society of Critical Care Medicine (SEPSIS-I) in infected patients. Patients with septic shock were also assessed using the SEPSIS-III definitions. Data regarding demographics, illness severity, comorbidities, microbiology, therapies, length of stay, and outcomes (dead/alive during 30 days) were recorded. Results: Of the 1499 patients included in the analysis, 237 (15.8%) had infection without SIRS, 163 (10.8%) had infection with SIRS, 260 (17.3%) had severe sepsis without shock, and 203 (13.5%) had septic shock. The mortality rates were higher in patients with severe sepsis (55.7%) and septic shock (70.4%) than those with infection alone (24.8%) and infection + SIRS (31.2%) (p < 0.001). According to SEPSIS-III, 104 (6.9%) patients had septic shock (mortality rate, 75.9%). The respiratory system (71.6%) was the most common site of infection, and Acinetobacter spp. (33.7%) were the most common isolated pathogen. Approximately, 74.9%, 39.1%, and 26.5% of Acinetobacter, Klebsiella, and Pseudomonas spp. isolates, respectively, were carbapenem-resistant, which was not associated with a higher mortality risk. Age, acute physiology and chronic health evaluation II score at ICU admission, sequential organ failure assessment score on study day, solid organ malignancy, presence of severe sepsis or shock, Candida spp. infection, renal replacement treatment, and a nurse-to-patient ratio of 1: 4 (compared with a nurse-to-patient ratio of 1:2) were independent predictors of mortality in infected patients. Conclusions: A high prevalence of sepsis and an unacceptably high mortality rate were observed in Turkish ICUs. Although the prevalence of carbapenem resistance was high in Turkish ICUs, it was not associated with a higher risk for mortality.Publication Metadata only Subcostal Transversus Abdominis Plane Block for Laparoscopic Sleeve Gastrectomy, Is It Worth the Time?(SPRINGER, 2019) CİNGİ, ASIM; Coskun, Muemin; Yardimci, Samet; Arslantas, Mustafa Kemal; Altun, Gulbin Tore; Uprak, Tevfik Kivilcim; Kara, Yalcin Burak; Cingi, AsimBackgroundObesity is a complex and multifactorial disease whose incidence has increased, making it a serious public health issue. Laparoscopic sleeve gastrectomy (LSG) is one of the most common surgical procedures that is chosen for bariatric surgery. Decreasing postoperative pain in these patients which will increase patients' compliance and quality of life will lead to better surgical results. This study aims to compare the effectiveness of trocar site infiltration versus bilateral subcostal transversus abdominis plane block (TAP) in controlling postoperative pain in patients.MethodsForty-five consecutive patients who have undergone LSG in xxx General Surgery Department have been enrolled in the study. Patients were divided into two groups according to the surgeon's choice. The first group underwent TAP block, while the second group underwent trocar site infiltration. Patients' pain was recorded via visual analogue scale (VAS) in postoperative periods.ResultsTwenty-nine female (69%) and 13 (31%) male patients were included in the study. Median age was 41 (18-58) and median BMI was 48 (41.1-68). When the VAS values were compared, in the TAPB group, 6th hour resting and coughing pain was statistically significantly less. Other VAS values measured while resting, coughing, and post-mobilization did not show significant differences. There were no significant differences between the groups' tramadol use.ConclusionsAfter LSG, TAP block and trocar site infiltration yield similar pain control. Due to the faster application and fewer side effects, we concluded that trocar site infiltration should be the intervention of choice in controlling postoperative pain in LSG.Publication Open Access The effects of pneumoperitoneum and patient position on the perfusion index and pleth variability index during laparoscopic bariatric surgery(MARMARA UNIV, FAC MEDICINE, 2020-03-31) ARSLANTAŞ, MUSTAFA KEMAL; Arslantas, Reyhan; Arslantas, Mustafa Kemal; Tore Altun, Gulbin; Corman Dincer, PelinObjective: Limited data are available on the use of the perfusion index (PI) and the pleth variability index (PVI) during laparoscopic bariatric suigery. We investigated the effects of pneumoperitoneum and the reverse Trendelenburg position on these indices. Materials and Methods: PI, PVI, heart rate (HR), blood pressure, SpO(2) and ventilation parameters were recorded before anaesthesia induction (T0), 5 min after endotracheal intubation (T1), immediately before surgery, after the patient had been in the reverse Trendelenburg position for 5 min (T2), after inflating the abdomen with CO2 in reverse Trendelenburg (T3), after the abdomen had been deflated (T4) and 5 min after extubation (T5). Results: General anaesthesia induced an increase in the PI (P<.001), and a decrease in the PVI (P=.002). The PI and PVI values were not affected during T2 or T3. Pneumoperitoneum caused an increase in mean arterial pressure (MAP) and a decrease in HR. PVI and MAP decreased during 14, but the PI and IHR remained unchanged. PVI, HR and MAP increased during T5. Conclusion: Our data suggest that the reverse Trendelenburg position and pneumoperitoneum did not affect the PI or PVI values, whereas deflation decreased the PVI in morbidly obese patients under general anaesthesia.Publication Open Access Serum vitamin D level variation in SIRS, sepsis and septic shock(MARMARA UNIV, FAC MEDICINE, 2019-10-31) BİLGİLİ, BELİZ; Gul, Fethi; Arslantas, Mustafa K.; Bilgili, Beliz; Besir, Ahmet; Kasapoglu, Umut S.; Karakurt, Sait; Cinel, IsmailObjectives: Vitamin D has potent immunomodulatory effects with the capability of acting as an autocrine and paracrine agent, and inhibits inflammatory signaling. In this study, our aim was to evaluate the relationship between vitamin D levels in systemic inflammatory response syndrome (SIRS), sepsis and, septic shock patients and outcomes. Patients and Methods: A total of 45 patients whose vitamin D levels were measured within the first 48 hours of Intensive Care Unit (ICU) admission and 20 healthy controls were studied prospectively. The patients were grouped as, SIRS (Group-I,n=10), sepsis (Group-II, n=25), septic shock (Group-III, n -10) and healthy subjects (Group-IV, n=20). Serum vitamin D levels were categorized as a deficiency (<= 15ng/mL), insufficiency (16-29ng/mL) and sufficiency (>= 30ng/mL). Demographic characteristics, Acute Physiology and Chronic Health Assessment II (APACHE-II) scores, and biochemical parameters were noted. Results: Vitamin D levels were significantly lower in all study groups compared to the control group (p<0.01), but were similar among the study groups. The hospital and ICU length of stay (LOS), and biochemical parameters were similar among the study groups. The mortality rates were 40% in Group I, 57 % in Group II, and 80 % in Group III. Conclusion: In our study patients with SIRS, sepsis and septic shock had lower serum 25-OH vitamin D levels compared to the control group. Our results are in line with the literature that supports a relationship between vitamin D deficiency and inflammation.
