A Practical Approach to Cerebro-Somatic Near-Infrared Spectroscopy and Whole-Body Ultrasound

A proposed algorithm for combining transcranial Doppler ultrasound monitoring with cerebral and somatic oximetry: a case report

“…In a systemic low flow situation, both cerebral blood flow estimated from TCD velocities and NIRS would have been reduced. 12 In our experience, air emboli detected by TCD will often be observed before RV failure becomes apparent on TEE examination, as in the current case, or before the appearance of electrocardiographic changes of ischemia. 13 Preferential embolization of air in the right coronary artery can be explained by the non-dependent position of its ostium in the aortic root.…”

Transcutaneous near‐infrared spectroscopy (NIRS) for monitoring kidney and liver allograft perfusion

“…Transcutaneous near‐infrared spectroscopy (NIRS) allows for non‐invasive, real‐time, continuous monitoring of regional oxygenation of the hemoglobin (rSrO2), which is an indirect measure of the blood flow and the metabolic state, of tissue placed deeper beyond the skin. Several clinical studies have tested the use of NIRS for monitoring cerebral and somatic perfusion in intensive care units 6 and the viability of soft‐tissue flaps 7 . Recently, it has been proposed for the surveillance of allograft perfusion too 8 …”

Combined cerebral and somatic near-infrared spectroscopy oximetry monitoring during liver surgery: an observational and non-interventional study

“…Most of its use has been in pediatric cardiac surgical patients [ 21 , 47 , 48 ]. Combining cerebral and somatic NIRS is useful to discriminate if a reduction in ScO 2 results from a central or peripheral process as we previously proposed [ 29 , 49 ]. For instance, if brain and somatic desaturation are present simultaneously, the etiology is unlikely to be cerebral in nature and could be hemorrhagic shock as we observed in Fig.…”

“…In patients having sustained severe trauma, somatic NIRS value have been associated with mortality, subsequent organ dysfunction, the need for massive transfusion or emergent surgery [23][24][25][26]. We have recently reported our experience using cerebral and somatic NIRS in liver transplantation [27,28] and proposed a combined cerebral and somatic algorithm [29]. However, no studies have examined intraoperative cerebral and somatic oxygen saturation as a predictor of postoperative complications after hepatic surgery.…”
