BACKGROUND: SARS-CoV2/COVID-19 emerged in China and caused a global pandemic in 2020. The mortality rate has been reported to be between 0% and 14.6% in all patients. In this study, we determined the clinical and laboratory parameters of COVID-19 related morbidity and mortality in our hospital. OBJECTIVES: Investigate the relationship between demographic, clinical, and laboratory parameters on COVID-19-related morbidity and mortality. DESIGN: Retrospective observational study. SETTINGS: Tertiary care hospital. PATIENTS AND METHODS: Patients diagnosed with COVID-19 pneumonia from March until the end of December were included in the study. MAIN OUTCOME MEASURES: The relationship between demographic, clinical, and laboratory parameters and the morbidity and mortality rates of patients diagnosed with COVID-19. SAMPLE SIZE: 124 patients RESULTS: The mortality rate was 9.6% (12/124). Coronary artery disease ( P <.0001) diabetes mellitus ( P =.04) fever (>38.3°C) at presentation ( P =.04) hypertension ( P <.0001), and positive smoking history ( P <.0001) were significantly associated with mortality. Patients who died were older, had a higher comorbid disease index, pneumonia severity index, fasting blood glucose, baseline serum creatinine, D-dimer, and had lower baseline haemoglobin, SaO 2 , percentage of lymphocyte counts and diastolic blood pressure. Patients admitted to the ICU were older, had a higher comorbidity disease index, pneumonia severity index, C-reactive protein, WBC, D-dimer, creatinine, number of antibiotics used, longer O 2 support duration, lower hemoglobin, lymphocyte (%), and baseline SaO 2 (%). CONCLUSIONS: Our results were consistent with much of the reported data. We suggest that the frequency, dosage, and duration of steroid treatment should be limited. LIMITATIONS: Low patient number, uncertain reason of mortality, no standard treatment regimen, limited treatment options, like ECMO. CONFLICT OF INTEREST: None.

Introduction The aim of this study is to evaluate the replantation success of single-dose infraclavicular brachial plexus block and continuous infraclavicular brachial plexus block (CIBPB) applied with bupivacaine and prilocaine in patients with finger amputation. Materials and Methods This prospective randomized nonblinded study was conducted between January 2012 and September 2017, and 47 patients, all male, were included. Patients were randomly separated into two groups as 23 patients CIBPB applied group (group A) and 24 patients single-dose infraclavicular block applied group (group B). In group B, after the effect of block is ceased, intravenous patient-controlled (PC) opioid analgesia and, where necessary, 1 mg/kg meperidine and 75 mg diclofenac sodium intramuscularly were alternately administered at 4 to 6 hours intervals. The average ages were 30.7 ± 10.06 and 29 ± 9.08, respectively. Replantations were applied as being two venous anastomoses to one artery, where possible. Hourly skin temperatures of fingers of the hands in which both surgeries applied and no surgery applied in both the groups were measured for 3 days with an infrared thermometer. Also, Numerical Rating Scale (NRS) evaluations in both the groups were performed in 3-hour intervals for 3 days. Results Replantations were successful in 22 patients in whom CIBPB was applied (95.6%) and in 19 patients in whom single block was applied (79.16%). Regarding the finger temperatures, no significant difference was detected between both the groups for 3 days following the operation. No significant difference was found between the length of hospital stays (4.73 ± 2.21—4.71 ± 1.53) and duration of operations (2.90 ± 0.73—2.83 ± 0.58). There was no significant difference between the temperature values of both the groups. NRS scores of group A were statistically significantly lower than those of group B. Conclusion In this prospective randomized study performed by using bupivacaine and prilocaine on 24 patients, the success rate of finger replantations with CIBPB was found to be higher. CIBPB is a very beneficial method that should be taken in consideration in hand injuries with anastomosis and high risk of vasospasm. Further studies with more number of cases would help reduce the question marks related with the success of this method.

BACKGROUND AND OBJECTIVESBrain natriuretic peptide (BNP) has a role in the regulation of body fluid volume and blood pressure (BP). BNP remains within a normal range during spinal anaesthesia (SA) in patients undergoing cesarean delivery. However, the effect of BNP on changes in BP during the perioperative period has not been evaluated. We aimed to investigate the effect of preoperative serum BNP on the risk of hypotension during cesarean delivery with SA.DESIGN AND SETTINGPatients were randomly selected among the patient group who were attending routine clinic visits for pregnancy monitoring. All had a healthy pregnancy and no other acute or chronic disease by their obstetrician. The study design was cross-sectional.PATIENTS AND METHODSPatients who had uncomplicated pregnancy process and no known medical disease were selected consecutively during their last outpatient clinical examination. Baseline BP was recorded before SA. Simultaneously, blood samples were drawn for routine biochemistry and BNP. BP, SaO2, and electrocardiography were monitored during surgery. Intraoperative hypotension (IOH) was defined as ≥25% decrease in mean arterial pressure (MAP) at the 5th minute of SA.RESULTSIn 41 term pregnant women, 18 of the 41 patients (43.9%) fulfilled the criteria for IOH, while 23 (56.1%) showed a decrease 13.1 (11.3%) and were classified as normotensive. Baseline BNP was significantly lower in patients with IOH compared with normotensive patients 45.7 (26.9) vs.70.2 (40.5); P=.05. Baseline BNP had no significant correlation MAP at any time point. Age, body mass index, hemoglobin, baseline MAP and heart rate were not different between patients with and without IOH.CONCLUSIONThose findings suggest that higher baseline BNP levels might have a protective role in development of hypotension in healthy term pregnant women during SA for cesarean delivery.
