Brief Summary
Surgery of large cerebellopontine angle (CPA) tumors (\>2 x 2 cm diameter), with compression of the pons exposes the patient to inadvertent parasympathetic nerve stimulation (IPNS) leading to bradycardia and asystole. The analgesia nociception index (ANI) monitor assesses the balance between analgesia and nociception through the detection of parasympathetic tone. ANI \>80 generally denotes excessive analgesia (EA). The main objective of this study was to determine whether ANI values for IPNS are different or the same as ANI values for EA. This study also aims at calculating the number of patients with IPNS and EA during surgery of large CPA tumours.

Outcome Measures
Primary Outcomes (2)
Differences in instantaneous ANI (ANIi) values during bradycardia versus ANIi values when Remifentanil effect size concentration >6ng/mL
ANI, HR and Remifentanil effect site concentration were continuously recorded with event markers on the ANI monitor at the onset of bradycardia (HR\<45 bpm) or Remifentanil effect site concentration\>6ng/mL
ANIi values recorded at Day 1 only during surgery (duration: 4-6 hours)
Differences in the area under the ROC curves between ANI values for IPNS and EA analgesia
ROC curves were built at different ANIi for IPNS or EA
ANIi values recorded at Day 1 only during surgery (duration: 4-6 hours)
Secondary Outcomes (1)
Percentages of IPNS and EA cases
Cases observed at Day 1 only during surgery (duration: 4-6 hours)
Study Arms (1)
Patients with large CPA tumors
Patients with large cerebellopontine angle tumors (\>2 x 2cm) undergoing elective surgery
Interventions
ANI profiles during IPNS (bradycardia/asystole) or excessive analgesia. During surgery continuous monitoring of ANI, HR and Remifentanil effect site concentration was done and recorded. Event markers were placed at the onset of bradycardia, asystole and the coincidence of ANI\>80 + Remifentanil \>6ng/mL). ANI values of 1 min before and 1 min after the event were used for analysis.
Eligibility Criteria

You may qualify if:
- patients undergoing elective surgery of large cerebellopontine angle tumors
You may not qualify if:
- age below 18yr
