Overview
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.

Arms & Interventions
haemodynamic parametres-guided deep sedation
propofol will be tirtrated in a single dose of 0,5 mg/kg of body weight to disappearance of cilliary reflex; in the case of heart rate and/or arterial blood pressure increase by 20% a rescue dose of fentanyl 0,5 mcg per kilogram of body weight will be administered
Intervention: rescue fentanyl
haemodynamic parametres-guided deep sedation
propofol will be tirtrated in a single dose of 0,5 mg/kg of body weight to disappearance of cilliary reflex; in the case of heart rate and/or arterial blood pressure increase by 20% a rescue dose of fentanyl 0,5 mcg per kilogram of body weight will be administered
Intervention: rescue propofol
SE-guided propofol-fentanyl deep sedation
propofol will be tirtrated in a single dose of 0,5 mg/kg of body weight to a target SE \< 80 alongside with a rescue dose 0,5 mcg per kilogram of body weight of fentanyl in the case of heart rate and/or arterial blood pressure increase by 20%
Intervention: rescue fentanyl
SE-guided propofol-fentanyl deep sedation
propofol will be tirtrated in a single dose of 0,5 mg/kg of body weight to a target SE \< 80 alongside with a rescue dose 0,5 mcg per kilogram of body weight of fentanyl in the case of heart rate and/or arterial blood pressure increase by 20%
Intervention: rescue propofol
AoA-guided propofol-fentanyl deep sedation
propofol will be tirtrated in a single dose of 0,5 mg/kg of body weight to a target SE \< 80 alongside with a rescue dose 0,5 mcg per kilogram of body weightof fentanyl in the case of increase of SPI value \> delta 15
Intervention: rescue fentanyl
AoA-guided propofol-fentanyl deep sedation
propofol will be tirtrated in a single dose of 0,5 mg/kg of body weight to a target SE \< 80 alongside with a rescue dose 0,5 mcg per kilogram of body weightof fentanyl in the case of increase of SPI value \> delta 15
Intervention: rescue propofol
Outcomes
Primary Outcomes
intraoperative pain perception: 11 points numeric rating scale
Time Frame: after 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 scale
Time Frame: immediately 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 Outcomes
- patient's satisfaction: 4 points numeric rating scale(2 hours after emergence from sedation)
- operator's satisfaction: 4 points numeric scale(immediately after the end of the procedure)
