Comparative, Randomized Trial of SPI-directed Intravenous Analgesia Using Metamizole With Tramadol Versus Preemptive Wound Infiltration Using 0,2 % Ropivacaine With Fentanyl or 0,2 % Bupivacaine With Fentanyl for Lumbar Discectomy

NCT02971540 NA COMPLETED

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.

Conditions

• Lumbar Disc Disease

Interventions

• Metamizol
• Tramadol
• Bupivacaine
• Ropivacaine
• control group

Primary outcomes

• pain perception intraoperatively — on-line based on SPI values
  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
