Abstract
Objective
Unexpected intraoperative movement may be detrimental during delicate surgery. This study tested retrospectively an algorithm based on beat-by-beat circulatory variables (incorporated into a Cardiovascular depth of anesthesia index: CARDEAN©) in relationship to unexpected movement, and compared its performance to that of the electroencephalogram (EEG)-derived index: BIS®-XP 4.0.
Methods
40 ASA I or II patients presenting for knee surgery had EEG (BIS® XP 4.0), beat-by-beat (Finapres®) finger non-invasive blood pressure (BP), conventional brachial BP and electrocardiogram (EKG) monitors attached. Anesthesia was induced and maintained with propofol and remifentanil. Before incision, the propofol concentration was set to maintain BIS <60. From incision to emergence, the anesthesiologist was denied access to BIS or Finapres. Anesthesia adjustment was titrated at the discretion of the anesthesiologist according to conventional signs only: brachial BP, EKG, eyelash reflex, movement. Occurrences of movement and eye signs (divergence of eyeballs, tears, corneal reflex, eyelash reflex) were observed. The CARDEAN algorithm was written retrospectively and tested vs. BIS.
Results
11 movements occurred in 8 patients. CARDEAN >60 predicted movement in 30% of the cases, 15 to 274 s before movement (sensitivity: 100%, specificity: 95%; relative operating curve ROC = 0.98; prediction probability pk = 0.98). BIS >60 predicted movement in 19% of cases (sensitivity: 64%; specificity: 94%, ROC: 0.85, pk: 0.85).
Conclusion
Retrospectively, a cardiovascular index predicted unexpected intraoperative movements. Prospective validation is needed.

Detailed description of the CARDEAN algorithm
Beat-by-beat R–R interval and SBP time-series were digitally filtered using a low-pass filter (cut-off = 0.1 Hz). Local minimums and maximums were detected. For each SBP rise higher than a threshold comprised between 2 and 5mmHg (e.g. hatched area) the following steps were performed. (a) The SBP rise time was calculated (time interval between the 2 opened circles). (b) The SBP area under the curve (AUC) was calculated with respect to the SBP value at the onset of the SBP rise (left opened circle). The AUC under the SBP curve was calculated over a period (ΔT) equal to 1.5 times the SBP rise time, with respect to the onset of the SBP rise. (c) The RR interval rise following the SBP rise was detected. (d) The R–R interval AUC was calculated with respect to the R–R interval value at the onset of the R–R interval rise (left opened circle). The AUC under the R–R interval curve, positive or negative, was calculated over a period of identical length (ΔT) as for the corresponding SBP rise, with respect to the onset of the R–R interval rise. The R–R interval curve between the 2 opened circles was named here R–R baroreflex response. (e) The R–R interval area to SBP area ratio (Area Ratio) was calculated (parameter p1). (f) The amplitude RR− of the R–R interval fall preceding the R–R baroreflex response was calculated (parameter p2). (g) The amplitude RR+ of the RR rise during the R–R baroreflex response was calculated. The parameter p3 = RR+/RR− was derived. (h) The parameter p4 was calculated as being the difference (ΔRR) between the RR value at the onset of the R–R baroreflex response (left opened circle) and the RR value at the end of the R–R baroreflex response (right opened circle). When (a) p1 was smaller than a threshold comprised between 1 and 3 and (b) p2 was greater than a threshold comprised between 40 and 80 and (c) p3 was smaller than a threshold comprised between 0.3 and 0.75 and (d) p4 was smaller than a threshold comprised between −20 and 10, CARDEAN index was set to a value greater than 60. This signs an “occluded” baroreflex response. If at least one of criteria 1–4 was not fulfilled, CARDEAN index was set to a value smaller that 60. This signs a normal baroreflex response. The precise value of thresholds were tuned retrospectively in order to achieve an acceptable fit between the CARDEAN index and the occurrence of movement.
