Brief Summary

The aim of this randomized prospective trial is to assess the utility of Adequacy of Anaesthesia technique (Response Entropy and Surgical Pleth Index) for monitoring pain perception intraoperatively and its influence on postoperative pain perception, both patients' and operators' satisfaction in patients undergoing colonoscopic procedures under intravenous sedation using propofol and fentanyl.

Detailed Description

Surgical Pleth Index (SPI) is reported to properly reflect nociception-antinociception balance in patients undergoing surgical procedures, where a value of 100 corresponds to a high stress level and a value of 0 to a low stress level; values near 50 or increase in value \> delta 10 correspond to the stress level which is known to reflect requirement for rescue analgesia.

The applicability of SPI- guided deep sedation regimen in colonoscopic procedures has not been previously studied. Additionally, depth of sedation markedly influences the nociception-antinociception balance so its monitoring also proved useful in procedures performed under deep sedation.

Therefore, we aim to investigate if both SPI-guided fentanyl administration alongside with State Entropy guided propofol aministration (Adequacy of Anaesthesia monitoring) versus State Entropy guided propofol aministration alongside with fentanyl titration based on haemodynamic parametres versus fentanyl titration based on haemodynamic parametres only influence both patients' or operator's satisfaction from anaesthetic management.

Primary Outcome Measures
NameTimeMethod
intraoperative pain perception: 11 points numeric rating scaleafter 2 hours after emergence from sedation

the patient will be asked if he/she had any reminiscence of pain perception during procedure of colonoscopy using 11 points numeric rating scale (0 - no pain, 10 - maximum pain)

postoperative pain perception: 11 points numeric rating scaleimmediately after emergence form sedation

the patient will be asked if he/she had any pain perception after emergence from sedation after procedure of colonoscopy using 11 points numeric rating scale (0 - no pain, 10 - maximum pain)

Secondary Outcome Measures
NameTimeMethod
patient's satisfaction: 4 points numeric rating scale2 hours after emergence from sedation

the patient will be asked if he/she was satisfied with sedation quality for the procedure of colonoscopy using 4 points numeric scale

operator's satisfaction: 4 points numeric scaleimmediately after the end of the procedure

the operator will be asked if he/she was satisfied with sedation quality for the procedure of colonoscopy using 4 points numeric scale
