Brief summary: This is a unicentric, prospective randomised trial that aims to evaluate the role of intra-operative monitoring of nociception through SPI (Surgical Pleth Index) in guiding analgesia and reducing opioid consumption in obese patients undergoing bariatric surgery.

We aim to enrol 40 patients having laparoscopic gastric sleeve surgery in the Cluj-Napoca County Hospital. They will be randomised into two groups, one with opioid administration during surgery guided by SPI, and the other one guided by anesthetist experience. We will monitor opioid consumption, pain scores during the first 90 minutes post-operatively, hemodinamic events during surgery and the duration between reversal of neuromuscular block and extubation.


Eligibility criteria: Inclusion Criteria:

* patients scheduled to laparoscopic gastric sleeve surgery in First Surgical Clinic, Cluj-Napoca County Hospital

Exclusion Criteria:

* drugs that affect the autonomic nervous system
* peripheral neuropathy
* altered renal/hepatic function
* chronic opioid use
* use of vaso-active drugs intra-operatively

Primary outcomes:
measure: Pain scores on the visual analog scale during the first 90 minutes post-operatively
timeFrame: during the first 90 minutes post-operatively
Secondary outcomes:
