Evaluation of continuous flash glucose monitoring in a pediatric ICU setting.
Glucose monitoring is of great importance among patients in intensive care units (ICU). The purpose of this study is to assess the performance of a new flash glucose monitoring (FGM) system in a pediatric ICU setting. Sixteen consecutive patients admitted in pediatric ICU aged > 4 years, expected length stay > 2 days and with no medication or existing diagnosis affecting glucose metabolism were enrolled. ⋯ Significant linear correlations between age and MARD values were observed. Surveillance error grid (SEG) analysis showed 92.04%, 94.67% and 95.52% of the readings in the none or slight risk zone respectively. FreeStyle Libre is well tolerated although not adequately accurate with a tendency to underestimate glucose levels in critically ill pediatric patients.

ReviewDoes nociception monitor-guided anesthesia affect opioid consumption? A systematic review of randomized controlled trials.
Monitors that estimate nociception during anesthesia may be used to guide opioid and other analgesics administration to optimize anesthesia care and possibly outcome. We reviewed the literature to evaluate current evidence of the effect of nociception-guided management over standard anesthesia practice during surgery. A systematic review of the literature on the effect of nociception monitoring on anesthesia practice was conducted. ⋯ On secondary outcomes, no consistent effect of nociception-guided anesthesia could be established. Although some nociception monitors show promising results, no definitive conclusions regarding the effect of nociception monitoring on intraoperative opioid consumption or other anesthesia related outcome can be drawn. Clinical trial number PROSPERO ID 102913.

Comparative StudyCardiac output estimation by multi-beat analysis of the radial arterial blood pressure waveform versus intermittent pulmonary artery thermodilution: a method comparison study in patients treated in the intensive care unit after off-pump coronary artery bypass surgery.
Cardiac output (CO) is a key hemodynamic variable that can be minimally invasively estimated by pulse wave analysis. Multi-beat analysis is a novel pulse wave analysis method. In this prospective observational clinical method comparison study, we compared CO estimations by multi-beat analysis with CO measured by intermittent pulmonary artery thermodilution (PATD) in adult patients treated in the intensive care unit (ICU) after off-pump coronary artery bypass surgery (OPCAB). ⋯ The percentage error was 40.7%. The four-quadrant plot-derived concordance rate was 88%. CO estimation by multi-beat analysis of the radial arterial blood pressure waveform (Argos monitor) shows reasonable agreement compared with CO measured by intermittent PATD in adult patients treated in the ICU after OPCAB.

Comparative StudyCardiac output estimation using multi-beat analysis of the radial arterial blood pressure waveform: a method comparison study in patients having off-pump coronary artery bypass surgery using intermittent pulmonary artery thermodilution as the reference method.
Pulse wave analysis enables stroke volume to be estimated from an arterial blood pressure waveform. Multi-beat analysis is a novel pulse wave analysis method. We aimed to investigate cardiac output (CO) estimations using multi-beat analysis of the radial arterial blood pressure waveform in patients undergoing off-pump coronary artery bypass surgery (OPCAB) using intermittent pulmonary artery thermodilution (PATD) as the reference method. ⋯ The mean of the differences between PATD-CO and MBA-CO was - 0.20 L/min with a standard deviation of ± 1.14 L/min and 95% limits of agreement of - 2.48 to + 2.08 L/min. The concordance rate for CO changes between PATD-CO and MBA-CO was 89%. CO estimations using multi-beat analysis (Argos monitor) show reasonable agreement and trending ability compared with PATD-CO as the reference method in adult patients during OPCAB.

Randomized Controlled Trial Comparative StudyComparison between two mathematical methods to estimate arterial occlusion pressure and tourniquet effectiveness in lower limb surgery: a prospective, randomized, double blind, comparative study.
The effectiveness of two different methods for calculating the arterial occlusion pressure (AOP) to set tourniquet inflation pressures were assessed in patients underwent knee arthroscopy. Eighty patients were included in this study. Tourniquet inflation pressure was set by adding 20 mmHg of safety margin above the AOP value which was calculated by either the Tuncali et al. formula or Hong-yun Liu et al. formula. ⋯ Also, there was no significant difference in surgeon rating of the bloodlessness of the surgical field, at the start, middle and end of surgery. Hong-yun Liu et al. mathematical formula was found to be less effective than Tuncali et al. formula to estimate the least effective tourniquet pressure in lower limb surgery and we might consider it invalid to be used in the lower limb.
