Study summary

Prospective, randomized, double-blinded, trial regarding the effect of local wound infiltration at the end of spine surgery; randomizing 1:1:1 between NaCl, Ropivacain, Levobupivacaine combined with Tramadol

Read the detailed description

Subcutaneous local wound injections with NaCl, Ropivacain or Levobupivacaine combined with Tramadol will be performed in a randomized, double-blinded manner at the end of spine surgery. Pain control, dosage of analgesics used, analgesics reduction compared to preoperative, wound healing problems and clinical outcome socres will be assessed up to 6 weeks after surgery
