First Objective

The results obtained of the first objective by the correlation show how similar the nociception monitors are between them are:

The Algiscan and Conox monitors demonstrated the highest capability in predicting nociception for Tetanus stimuli. On the other hand, some indices of ANI monitors show more correlation with the qCO index.

Second Objective

The conclusions for the second objective that Irene found was:

In the Tetanus statistical analysis, Algiscan and the Conox were the monitors with best capability.

But the Laringeal mask airway statistical analysis was so different from Tetanus one. The best monitor was qCO.

These changes can be explained for the following reasons.

The LMA stimulus is quite different from the rest of surgical stimuli and the Tetanus one.

Secondly, the introduction of the LMA in the patient leads to a change in the oxygen concentration in blood. That could be affecting the data (ECG and EEG) used to calculate the nociception.

Third Objective

The last analysis was performed in order to identify the indices that negatively affect the nociception prediction. Many parameters were studied, but most of them were not significant.

But she found that the age of the patient and the Burst Suppression could be affecting the nociception indices based on EEG signals in a negative way.

So, in order to confirm the findings of this study with more statistical significance, the number of surgeries with all the monitors need to be increased.

On the other hand, analyzing the patient before surgery, to obtain more information, might improve the performances of the nociception index.
