Clinical Trial Summary

The aim of this randomized trial is to assess the efficacy of analgesia for lumbar discectomy and compare Numerical Rating Scale (NRS) with Surgical Pleth Index (SPI) for monitoring pain perception postoperatively.

Patients received either preemptive local tissue infiltration at surgical site using either 0,2% ropivacaine with fentanyl or 0,2% bupivacaine with fenthanyl or preemptive intravenous infusion using metamizole and tramadol.

Description:

Monitoring depth of anaesthesia using spectral entropy (SE) and quality of neuromuscular block are routine in modern anaesthesia, whereas monitoring of analgesia still requires further studies. Recently, the Surgical Pleth Index (SPI) was added as a surrogate variable showing the nociception-antinociception balance into abovementioned parametres constituting a novel approach in monitoring patients intraoperatively, known as adequacy of anaesthesia (AoA) or tailor-made anaesthesia. This study aims at evaluating utility of SPI-directed analgesia in patients undergoing general anaesthesia (GA) where analgesia intraoperatively will be achieved either with regional preemptive wound infiltration using 0,2 % ropivacaine with fentanyl or 0,2 % bupivacaine with fentanyl or intravenous analgesia using continuous infusion of metamizole with tramadol for lumbar discectomy. Intraoperatively, SPI value will be recorded with sampling frequency of 1 minute. When SPI value reaches a level higher than 15 SPI points above basic level, a rescue dose of 1mg/kg body weight of fentanyl will be administered intravenously every 5 minutes until SPI value decreases to basic level calculated previously before operation started.

Additionally, the investigators will compare Numerical Rating Scale (NRS) with Surgical Pleth Index (SPI) values for monitoring the efficacy of analgesia postoperatively. After emergence from GA patients will be questioned in terms of their pain intensity in a scale 0-10. In the case of pain perception above 3, a bolus of 2mg of morphine will be administered intravenously every 10 minutes until pain perception will be lower than 4. SPI values will be recorded every 1 minute and analysed for aute pain (NRS 7-10), average (4-6) and mild pain perception intervals to assess if there exists a correlation between NRS and SPI.

In addition, some patients develop Failed Back Surgery Syndrome (FBSS) following lumbar surgeries so the investigators will aim to analyze if SPI-directed analgesia intra- and post-operatively reduces rate of FBSS. After 5 months after operation patient will be surveyed using melzack protocol to assess the rate of FBSS as well as symptoms of chronic pain.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	postoperative persistent pain	The investigators will compare the efficacy of analgesia postoperatively according to technique of analgesia used preoperatively: either local woung inflitration or intravenous infusion. The investigators will use melzack to assess the rate of the post-operative persistent pain. Patients will be invited to pay a control visit in the clinic and asked to describe their pain intensity and specify its characteristic using a set of adjectives characterizing their pain perception. Afterwards, pain perception of patients will be analyzed using specified scale when each adjective is attributed points and sum of points gathered in the questionaire indicates probability of presence of postoperative perception pain using melzack questionnaire.	up to 6 months
Other	postoperative FBSS	The investigators will compare the efficacy of analgesia postoperatively according to technique of analgesia used preoperatively: either local woung inflitration or intravenous infusion. The investigators will use FBSS scale to assess the presence of FBSS. Patients will be invited to pay a control visit in the clinic to be diagnosed for symptoms of FBSS: pain intensity, disability, depression scores, temperament and character profile determined by the visual analogue scale (VAS), Roland Morris Disability Index, Beck Depression Inventory, and Temperament and Character Inventory.	up to 6 months
Primary	pain perception intraoperatively	The investigators will compare the efficacy of analgesia intraoperatively according to technique of analgesia used preoperatively: either local woung inflitration or intravenous infusion. The investigators will administer a resuce dose of fentanyl intravenously in a dose of 1 mcg per kg of body weight in the case when SPI value increases over 15 points in SPI scale every 5 minutes untill SPI value decreases back to baseline value	on-line based on SPI values
Secondary	pain perception postoperatively	The investigators will compare the efficacy of analgesia postoperatively according to technique of analgesia used preoperatively: either local woung inflitration or intravenous infusion. The investigators use NRS and compare it with SPI values. Additionally, The investigators will observe SPI variations as a reaction to morphine administration intravenously in the case of acute or moderate pain.	2 hours after discharge to postoperative unit.
