“…Table 4 provides an overview of selected studies, which further validate the measuring accuracy of the ClearSight ® in different cohorts. Our observations that the deviation of systolic blood pressure measurements by ClearSight ® are outside the AAMI limits confirm the results of the study by Tani et al, Rogge et al and Schumann et al [ 14 , 20 , 21 ]. The largest cohort was studied by Schumann et al ( n = 90) and Rogge et al, with the most data points of almost 100,000 [ 14 , 21 ].…”

The close monitoring of blood pressure during a caesarean section performed under central neuraxial anaesthesia should be the standard of safe anaesthesia. As classical oscillometric and invasive blood pressure measuring have intrinsic disadvantages, we investigated a novel, non-invasive technique for continuous blood pressure measuring. Methods: In this monocentric, retrospective data analysis, the reliability of continuous non-invasive blood pressure measuring using ClearSight® (Edwards Lifesciences Corporation) is validated in 31 women undergoing central neuraxial anaesthesia for caesarean section. In addition, patients and professionals evaluated ClearSight® through questioning. Results: 139 measurements from 11 patients were included in the final analysis. Employing Bland–Altman analyses, we identified a bias of −10.8 mmHg for systolic, of −0.45 mmHg for diastolic and of +0.68 mmHg for mean arterial blood pressure measurements. Pooling all paired measurements resulted in a Pearson correlation coefficient of 0.7 for systolic, of 0.67 for diastolic and of 0.75 for mean arterial blood pressure. Compensating the interindividual differences in linear regressions of the paired measurements provided improved correlation coefficients of 0.73 for systolic, of 0.9 for diastolic and of 0.89 for mean arterial blood pressure measurements. Discussion: Diastolic and mean arterial blood pressure are within an acceptable range of deviation from the reference method, according to the Association for the Advancement of Medical Instrumentation (AAMI) in the patient collective under study. Both patients and professionals prefer ClearSight® to oscillometric blood pressure measurement in regard of comfort and handling.

Background: acute kidney injury is a common complication in critically ill patients and it is commonly associated with high mortality and morbidity with adverse short and long term outcome. bjectives: The main objective of this study was to determine the frequency of acute kidney injury in ICU patients in Omdurman teaching hospital. And to assess the risk factors associated with the development of acute kidney injury (AKI) in a critically ill patient. We also intended to correlate acute kidney injury with the primary disease required admitting to ICU and find out the impact of acute kidney injury in ICU outcomes. Methods: In this descriptive prospective, cohort hospital-based study, 211 patients were studied and followed up during admission in ICU using standardized questionnaire to collect clinical data and investigation Results: a total of 61 patients has been included in the study developed renal impairment during their stay in ICU 39 (64%) patients were males and 22 ( 36%) were female mean age was 41 ± 5 renal impairment developed after mean of 5 days of admission and the most common cause was decreased level of consciousness and severe hypotension. sepsis accounting for 40% of the admission. The outcome in ICU showed that the mortality rate was high up to 41% in kidney injury patients Sepsis account for over 96 % (24 patients) who have passed away. Conclusions: development of AKI in ICU is an important risk factor for poor outcomes in critically setting. Prevention is the best method for avoiding AKI, with the early identification and recognition of high-risk patients.

Since blood pressure tends to be unstable during surgery, an arterial catheter is often inserted to monitor arterial pressure continuously during general anesthesia. However, there are some situations wherein arterial cannulation is not allowed. ClearSight System enables noninvasive continuous monitoring of arterial pressure and derives variables via a single finger cuff without arterial cannulation. We describe two cases of end-stage renal disease patients who were hemodynamically unstable during surgery. In these cases, rapid and appropriate management was possible using the ClearSight System in a situation where the arterial puncture was difficult.
