INTRODUCTION The Association of Anaesthetists of Great Britain and Ireland (AAGBI) guidelines Recommendations for standards of monitoring during anaesthesia and recovery state that cardiovascular monitoring for induction of general anaesthesia should include pulse oximetry and non-invasive blood pressure measurement, but recognise that young patients may not co-operate sufficiently to allow this. The aim of this study was to look at levels of compliance possible for pulse oximetry and non-invasive blood pressure measurement, in a population known to be unco-operative with therapeutic interventions. PATIENTS AND METHODS A retrospective review of 500 records of patients attending for chair dental general anaesthesia was carried out. It was recorded whether pre-operatively pulse oximetry and non-invasive blood pressure measurement had been allowed in addition to the child's age and sex. RESULTS Of the children, 52% were male and 48% were female. The age range was 2–15 years. Overall, 448 children co-operated with both pulse oximetry and non-invasive blood pressure measurement. Co-operation appeared to increase with increasing age. DISCUSSION Of the children, 90% were co-operative with pre-operative monitoring. It could easily be assumed that many of these children, who are referred for general anaesthesia because they are less co-operative than their peers, would not allow proper pre-operative cardiovascular monitoring. This does not appear to be the case. CONCLUSIONS The majority of children, including the very young, attending for chair dental general anaesthesia, will co-operate sufficiently to allow cardiovascular monitoring during induction of anaesthesia, even though the majority will not tolerate exodontia under local anaesthesia.

Induction Of Anaesthesia

Background: Continuous cardiovascular monitoring as part of management of high-risk surgical patients is widely practiced, however the role of continuous monitoring as part of routine management in low-risk surgical patients is unclear. Our aim was to investigate haemodynamic and Bispectral Index (BIS) changes in healthy patients undergoing surgery following induction of anaesthesia with propofol using a continuous non-invasive blood pressure device (LiDCO rapid™). We sought to obtain detailed monitoring of cardiovascular parameters from the pre-induction stage. Methods: This prospective, observational single-centre study was conducted at a London teaching hospital between June-November 2014. Patients aged between 18-45 years, American Society of Anesthesiologists grade I-II undergoing elective lower-limb arthroscopic procedures were included. Variables including heart rate (HR), mean arterial pressure (MAP), stroke volume (SV), cardiac output (CO), systemic vascular resistance (SVR) and BIS were recorded continuously prior to induction and up to 3-minutes after. Results: The following relative haemodynamic changes were noted between baseline and 1-minute post-induction with propofol: CO +15.2%, HR +10.1%, SVR -22.9% and MAP -10.1% (p<0.001 for each parameter). There was a mean change of: HR -10.1%, CO -14% and MAP -18.0%(p<0.001 for each parameter) between baseline and 3-minutes post-induction. Median change of BIS was -61.7% (p<0.001) between baseline and 3-minutes post-induction. Significant, positive correlations were noted between MAP and BIS at 30-seconds (r=0.60, p<0.001) and 1-minute post-induction (r=0.61, p<0.001). Conclusion: Our study shows that healthy patients undergoing continuous minimally invasive orthopaedic surgery experience significant haemodynamic and BIS changes following induction of anaesthesia. Our findings highlight the importance of baseline cardiovascular and BIS monitoring as part of routine perioperative management.

Abstract Quantitative and multiparametric blood analysis is of great clinical importance in cardiovascular disease diagnosis. Current blood analysis methods are typically restricted to invasiveness, bulky instruments and complicated clinical procedures. Wearable devices can realize on-skin assessment of several vital signals but generally exhibit very limited blood analyzing functions. Here, we report a flexible optoacoustic blood stethoscope (OBS) for multiparametric cardiovascular monitoring, bypassing the need for invasive procedures. The device features the light delivery elements for blood illumination and the piezoelectric acoustic elements capable of capturing the light-induced acoustic waves. This flexible device can adhere to the skin for continuous and non-invasive in-situ monitoring of multiple cardiovascular biomarkers, including hypoxia, drug concentration decay, and hemodynamics, which can be further visualized with the tailored 3D algorithm. Demonstrations on both in-vivo animal trials and human subjects highlight the OBS's unique potential to provide a new avenue for cardiovascular disease diagnosis and prediction.

Cardiovascular instability is one of the main reasons for admission to intensive care. Situations such as hypovolaemia, heart failure, and vasoplegia are often mixed, between them making the diagnosis more challenging. Attention to details and careful monitoring are essential at this stage. This chapter discusses cardiovascular monitoring and includes discussion on electrocardiograph monitoring, arterial pressure monitoring, insertion of central venous catheters, common problems with central venous access, pulmonary artery catheters, echocardiography, clinical applications of echocardiography in the intensive care unit, Doppler, pulse pressure algorithms, non-invasive methods, monitoring mean systemic filling pressure, and detection of volume responsiveness.
