Background/aim: In this study, we aimed to evaluate the initial hematological findings analyzed on admission in confirmed COVID-19 patients who were transferred to the intensive care unit (ICU), to predict possible hematological indices. Materials and methods: Initial neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), monocyte to lymphocyte ratio (MLR), red cell distribution width to platelet ratio (RPR), mean platelet volume to platelet ratio, and lymphocyte multiplied by platelet count (LYM x PLT), of 695 patients with laboratory-confirmed COVID-19 were investigated and compared between the mild/moderate and severe groups. Results: The proportion of COVID-19 cases admitted to ICU was 3.9%. The median age of patients admitted to ICU was significantly higher than those who were not; (68.5 (interquartile range (IQR); 21.5) years vs. 41.0 (IQR; 15.7) years; p <0.001). Severe cases had higher NLR (6.6 vs 2.4; P <0.001), and MLR (0.40 vs 0.28; P=0.004) and lower PLR (180.0 vs 129.0; P <0.001) compared to that of mild or moderate patients. Among all of the parameters, the ROC curve of NLR gave us the best ability to distinguish serious patients at an early stage (AUC = 0. 819, 95% confidence interval 0.729-0.910; p<0.001). Conclusion: These data showed that age, initial NLR, PLR, and LYM x PLT were associated with the severity of COVID-19 disease and patients' need for the ICU. Therefore, initial hemogram parameters may be essential to predict the prognosis of COVID-19 patients.
Rationale, aims, and objectives: Pressure ulcers (PUs), which are preventable complications, increase the cost of health care and the risk of prolonged hospital stay, as well as morbidity and mortality. In this study, we aimed to describe the prevalence, clinical features, and risk factors for PUs among hospitalized patients. Method: This study was cross-sectional and conducted over a single day in all the care units. Data were recorded on a patient observation form that included demographic data, diagnosis of admission to the hospital or intensive care unit (ICU), comorbidity and chronic diseases, location, stage of PU, and Braden Scale score. Acute physiology and chronic health evaluation (APACHE) II score, Glasgow coma score (GCS), PaO 2 /FiO 2 ratio, and albumin level were recorded for ICU patients. Results: A total of 1548 adult patients participated in the study. Of these patients, 177 (11.43%) had PU. The patients with PU had more advanced age, lower body mass index (BMI), and longer duration of hospital and ICU stay (for all P = .001). Evaluation of PU in the first 24 hours after hospital admission and the last PU evaluation time also showed a significant effect (both P = .001). Braden Scale score less than or equal to 13 in the first evaluation after hospital admission increased the risk of PU. Albumin was 2.78 ± 0.57 gm/dL in ICU patients, and albumin level was significantly lower in patients with PU (P = .001). PUs were located mainly in the sacrum (47.59%) and were classified as stage II (42.76%) for all patients. Conclusions: The prevalence of PU is related to the age and severity of patient clinical status, as predicted by the Braden Scale score and APACHE II score, and length of hospital and ICU stay. Low albumin level is also related to development of PUs in ICU patients.
We examined the changes in circulating choline status in humans in response to major surgery by measuring serum free and phospholipid-bound choline concentrations before, during and 1-72 h after total abdominal hysterectomy, off-pump coronary artery graft surgery or brain tumor surgery. Preoperatively, the mean serum free and phospholipid-bound choline concentrations in patients scheduled for abdominal hysterectomy (n = 26), off-pump coronary artery grafting surgery (n = 34) or brain tumor surgery (n = 24) were 12.3 +/- 0.5, 12.1 +/- 0.4 and 11.4 +/- 0.4 micromol/l, and 2495 +/- 75, 2590 +/- 115 and 2625 +/- 80 micromol/l, respectively. Serum free choline and phospholipid-bound choline concentrations decreased from these baseline values to 8.8 +/- 0.7 (p < 0.001), 8.8 +/- 0.5 (p < 0.001) and 8.2 +/- 0.4 micromol/l (p < 0.001), and 2050 +/- 108 (p < 0.001), 2166 +/- 59 (p < 0.001) and 1884 +/- 104 micromol/l (p < 0.001) at 1 h after hysterectomy, off-pump bypass graft surgery or brain tumor surgery, respectively. They remained at these low levels for 24 h and then gradually increased towards the preoperative values at 48-72 h postoperatively. Serum cortisol increased postoperatively in all surgical patients for 24 h and its levels were inversely correlated with serum free and bound choline concentrations. These results show that circulating free and bound choline concentrations decrease for 72 h after total abdominal hysterectomy, off-pump coronary artery graft surgery or brain tumor surgery in humans.
Background:The importance of the characteristics of anesthesia and postoperative residual curarization (PORC) in the elderly population should be a growing concern in this century. Aims: To investigate the effect of sugammadex on the duration of the recovery from neuromuscular blocking agents and postoperative residual curarization in the young elderly and middle-aged elderly patients who underwent elective laparoscopic cholecystectomy, followed by a train of four (TOF) watch monitorization. Study Design: Prospective clinical trial study. Methods: Sixty patients over the age of 65 with American Society of Anesthesiologists I-III were divided into two groups according to their age (65-74 years old and ≥75 years old). Patients received sugammadex (2.0 mg/ kg iv) at the reappearance of the second twitch of the TOF as an agent for reversal of neuromuscular blockage at the end of surgery. Patients were extubated at the time of TOF ≥0.9. The patients' TOF responses were evaluated with regards to PORC in at the 5th minute and were followed up for one hour in the recovery room. Reintubation was applied for those patients who developed PORC and had peripheric oxygen saturation <90% despite being given 6 L oxygen per min with a face mask. Results: The onset time of neuromuscular blocking agent and time from T 2 to achieve TOF ratio 90% (the duration of sugammadex effect) or over were found to be longer in the middle-aged elderly group than in the young elderly group. A statistically significant relationship was found between age and the duration of TOF ratio to reach 0.9 in the same direction. The PORC incidence and rate of reintubation were found to be 1.7% in all patients. Conclusion: In our opinion, it is necessary to remember that the duration of sugammadex effect on the recovery period is prolonged for patients who are aged ≥75 years compared to patients aged between 65-74 years. (ClinicalTrials.gov Identifier: ACTRN12615000758505) Keywords: Elderly, postoperative residual curarization, reintubation, sugammadex Young elderly people, middle-aged elderly people, and old elderly people have been classified, respectively, between 65-74 years of age, between 75-84 years of age, and over age 84 by gerontologists (1). A number of studies have indicated that the prevalance of postoperative residual curarization (PORC) increases with age (2,3).The principle of train of four (TOF) Watch was to indicate a pattern of stimulation that did not require the comparison of evoked responses to a control response obtained before administration of a neuromuscular blocking agent (NMBA). As well as enabling the observer to compare T 1 (first twitch of the TOF) to T 0 (control), it also enables comparison of T 4 (fourth
Objective We investigated the frequency of apnea tests, and the use of ancillary tests in the diagnosis of brain death in our hospital, as well as the reasons for not being able to perform apnea testing and the reasons for using ancillary tests. Methods In this retrospective study, the files of patients diagnosed with brain death between 2012 - 2018 were examined. The preferred test was determined if an ancillary test was performed in the diagnosis of brain death. The rate and frequency of use of these tests were analyzed. Results During the diagnosis of brain death, an apnea test was performed on 104 (61.5%) patients and was not or could not be performed on 65 (38.5%) patients. Ancillary tests were performed on 139 (82.8%) of the patients. The most common ancillary test was computed tomography angiography (79 patients, 46.7%). Approval for organ donation was received in the meetings with the family following the diagnosis of brain death for 55 (32.5%) of the 169 patients. Conclusion We found an increase in the rate of incomplete apnea tests and concordantly, an increase in the use of ancillary tests in recent years. Ancillary tests should be performed on patients when there is difficulty in reaching a decision of brain death, but it should not be forgotten that there is no worldwide consensus on the use of ancillary tests.
Objective: In this study, it was aimed to compare various parameters during surgery and postoperative cognitive functions in patients undergoing coronary artery bypass graft (CABG) surgery using different levels of perioperative oxygen.Methods: One hundred patients scheduled for elective CABG surgery were included in the study. The patients were divided into two groups according to arterial oxygen levels during surgery. In the normoxia group (NG) (n = 50), partial arterial oxygen pressure (PaO 2 ) was between ≥100 and <180 mmHg with at least 40% fraction of inspired oxygen (FiO 2 ) mechanical ventilation (MV), and in the hyperoxia group (HG) (n = 50), PaO 2 was ≥180 mmHg with 100% FiO 2 MV. Hemodynamic parameters, peripheral oxygen saturation (SpO 2 ), regional cerebral oxygen saturation (rSO 2 ) measured from bilateral sensors, and blood gas values were recorded at the planned measurement times. Postoperative features (mortality and infection rates, length of stay in the hospital, and intensive care unit) and complications of the patients have been recorded (low cardiac output syndrome, renal failure, delirium). Mini-Mental State Examination (MMSE) test was applied to the patients before and at the 12th, 24th hours; on the first, third, sixth months after surgery.Results: Extubation time was found to be shorter in NG (p < .05). Between the groups, rSO 2 and mean arterial pressure were found to be significantly lower in HG at the time of T4 measurement (p = .042, p = .038, respectively). MMSE values of the groups at the first, third, and sixth months were found to be significantly higher in NG (p = .017, p = .014, p = .002, respectively). Conclusion:Hyperoxemia application during CABG may be associated with worse postoperative late-term cognitive functions.
The purpose of our study it was aimed to determine the effectiveness of two different Lung ultrasonography (LUS) methods that can be used in the diagnosis of COVID-19 and to investigate its correlation with computed tomography (CT). Methods:In this prospective ,randomized and single blind study 60 patients with COVID-19 were included the study.Patients were randomized to either Group 12 zone LUS (n:30) or Group 14 zone LUS (n:30) .The evaluation parameters were to determine the correlation between LUS and Thorax-CT scores. The secondary outcome measure examined the characteristic features of the findings in Thorax-CT and LUS. Results:The study was completed with a total of 59 patients .A moderate and high degree correlation was found between the CT and LUS scores calculated according to the total score in the 12-zone and 14-zone study groups. There was no statistically significant difference between the groups in terms of lesion types detected in patients on LUS and CT (p<0.05).Left lung lower lobe CT scores in the 14-zone study group were statistically significantly lower than the 12-zone group (p= 0.019).Left lower lobe CT LUS score correlation was highly correlated in 14 regions examined group (p <0.001/r: 0.954). Conclusions:The results of our study indicated that the two different LUS examination methods performed on the different patients had similar findings in terms of diagnosis and their correlation with the results of the CT.
