Background.

Near-infrared spectroscopy is a potential tool for measuring adequacy of cerebral oxygenation during cardiac operations. The cerebral microcirculation is predominantly venous (by volume) and therefore regional cerebral oxygenation measured by near-infrared spectroscopy should reflect jugular bulb venous saturations.

Methods.

We compared simultaneous regional cerebral oxygenation and jugular bulb venous saturation measurements in 40 children (median age, 4.5 years; range, 2 weeks to 14.5 years) in the cardiac catheter laboratory (n = 29) and during cardiac operations (n = 11).

Results.

For all patients combined the correlation between regional cerebral oxygenation and jugular bulb venous saturation was 0.69 (p < 0.0001) and was similar for the two groups. For individual children undergoing cardiac operations excellent correlations were obtained (r = 0.78 to 0.96; median, 0.91). However, at low values of jugular bulb venous saturation, regional cerebral oxygenation tended to run high, whereas the converse was true for high values of jugular bulb venous saturation.

Conclusions.

These findings suggest that near-infrared spectroscopy may be a useful tool for assessing intravascular cerebral oxygenation during pediatric cardiac operations. Prospective studies of neurologic outcome will be required to establish the value of this technique for assessing the adequacy of cerebral protection.

Neuromonitoring and Neurocognitive Outcomes in Cardiac Surgery: A Narrative Review
2022, Journal of Cardiothoracic and Vascular Anesthesia
Neurocognitive dysfunction after cardiac surgery can present with diverse clinical phenotypes, which include postoperative delirium, postoperative cognitive dysfunction, and stroke, and it presents a significant healthcare burden for both patients and providers. Neurologic monitoring during cardiac surgery includes several modalities assessing cerebral perfusion and oxygenation (near-infrared spectroscopy, transcranial Doppler and jugular venous bulb saturation monitoring) and those that measure cerebral function (processed and unprocessed electroencephalogram), reflecting an absence of a single, definitive neuromonitor. This narrative review briefly describes the technologic basis of these neuromonitoring modalities, before exploring their use in clinical practice, both as tools to predict neurocognitive dysfunction, and with a bundle of interventions designed to optimize cerebral oxygen supply, with the aim of reducing postoperative delirium and cognitive dysfunction following cardiac surgery.
Clinical and Technical Limitations of Cerebral and Somatic Near-Infrared Spectroscopy as an Oxygenation Monitor
2021, Journal of Cardiothoracic and Vascular Anesthesia
Cerebral and somatic near-infrared spectroscopy monitors are commonly used to detect tissue oxygenation in various circumstances. This form of monitoring is based on tissue infrared absorption and can be influenced by several physiological and non-physiological factors that can induce error in the interpretation. This narrative review explores those clinical and technical limitations and proposes solutions and alternatives in order to avoid some of those pitfalls.
Cerebral regional oxygen saturation during cardiopulmonary resuscitation and return of spontaneous circulation: A systematic review and meta-analysis
2021, Resuscitation
Predicting the return of spontaneous circulation (ROSC) during cardiopulmonary resuscitation in victims of cardiac arrest (CA) remains challenging. Cerebral regional oxygen saturation (rSO2) measured during resuscitation is feasible, and higher initial and overall values seem associated with ROSC. However, these observations were limited to the analysis of few small single-centre studies. There is a growing number of studies evaluating the role of cerebral rSO2 in the prediction of ROSC.
We conducted an updated meta-analysis aimed at investigating the association of initial and overall values of cerebral rSO2 with ROSC after CA. We performed subgroups analyses according to the location of CA and conducted a secondary analysis according to the country where the study was conducted (resuscitation practice varies greatly for out-of-hospital CA).
We included 17 studies. Higher initial rSO2 values (11 studies, n = 2870, 16.6% achieved ROSC) were associated with ROSC: Mean Difference (MD) -11.54 [95%Confidence Interval (CI)-20.96, -2.12]; p = 0.02 (I² = 97%). The secondary analysis confirmed this finding when pooling together European and USA studies, but did not for Japanese studies (p = 0.06). One multi-centre Japanese study was an outlier with large influence on 95%CI. Higher overall rSO2 values during resuscitation (9 studies, n = 894, 33.7% achieving ROSC) were associated with ROSC: MD-10.38; [-13.73, -7.03]; p < 0.00001 (I² = 77%). All studies were conducted in Europe/USA.
This updated meta-analysis confirmed the association between higher initial and overall values of cerebral rSO2 and ROSC after CA. However, we found geographical differences, since this association was not present when Japanese studies were analysed separately.

The Association of Cerebral Desaturation During One-Lung Ventilation and Postoperative Recovery: A Prospective Observational Cohort Study
2021, Journal of Cardiothoracic and Vascular Anesthesia
This study was designed to investigate whether cerebral oxygen desaturations during thoracic surgery are predictive of patients’ quality of recovery. As a secondary aim, the authors investigated the relationship among cerebral desaturations and postoperative delirium and hospital length of stay.
This study was a prospective observational cohort study.
A single tertiary-care medical center from September 2012 through March 2014.
Adult patients scheduled for elective pulmonary surgery requiring one-lung ventilation.
All patients were monitored with the ForeSight cerebral oximeter.
The primary assessment tool was the Postoperative Quality of Recovery Scale. Delirium was assessed using the Confusion Assessment Method. Of the 117 patients analyzed in the study, 60 of the patients desaturated below a cerebral oximetry level of 65% for a minimum of 3 minutes (51.3%). Patients who desaturated were significantly less likely to have cognitive recovery in the immediate postoperative period (p = 0.012), which did not persist in the postoperative period beyond day 0. Patients who desaturated also were more likely to have delirium (p = 0.048, odds ratio 2.81 [95% CI 1.01-7.79]) and longer length of stay (relative duration 1.35, 95% CI 1.05-1.73; p = 0.020).
Intraoperative cerebral oxygen desaturations, frequent during one-lung ventilation, are associated significantly with worse early cognitive recovery, high risk of postoperative delirium, and prolonged length of stay. Large interventional studies on cerebral oximetry in the thoracic operating room are warranted.
Near-Infrared Spectroscopy in Pediatric Congenital Heart Disease
2020, Journal of Cardiothoracic and Vascular Anesthesia
Near-infrared spectroscopy (NIRS) is widely used to monitor tissue oxygenation in the pediatric cardiac surgical population. Clinicians who use NIRS must understand the underlying measurement principles in order to interpret and use this monitoring modality appropriately. The aims of this narrative review are to provide a brief overview of NIRS technology, discuss the normative and critical values of cerebral and somatic tissue oxygen saturation and the interpretation of these values, present the clinical studies (and their limitations) of NIRS as a perioperative monitoring modality in the pediatric congenital heart disease population, and introduce the emerging and future applications of NIRS.
Cardiopulmonary Bypass and Management
2019, A Practice of Anesthesia for Infants and Children
Cardiopulmonary bypass (CPB) is an imminent element of today's cardiac surgery. Major differences not only exist in setup and materials, but also in management strategies. The phases of CPB are similar to the adult, but the effects on the body and the physiological disturbances are far more pertinent. Hemodilution is the major hematologic disturbance that leads to coagulation deficiencies and challenges the oxygen transport capacities of the body. Hemodilution and the membrane oxygenator itself change the pharmacokinetics and pharmacodynamics of most anesthetics in use. Physiological limits are permanently reached during pediatric cardiac surgery and are most obvious during the care of Jehova's Witness patients. Lower body temperatures than in adults are routinely used which influences acid base management. Special techniques applied are deep hypothermic circulatory arrest and selective cerebral perfusion which enable a broad spectrum of today's congenital cardiac surgery. Despite technical advances widespread effects on the body systems remain and these changes can prolong the postoperative course and endanger a primarily successful repair.
