Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine whether the use of oral pregabalin 150 mg as premedication reduces the amount and degree of postoperative pain.

Furthermore the purpose of this study is to determine whether the use of oral pregabalin 150 mg as premedication reduces anxiety prior to anaesthesia in these patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The mechanism of development of postoperative pain is complex. Central and peripheral sensitization are playing an important role and this can lead to postoperative hypersensitization. Several studies have shown, that gabapentin can be effective to reduce sensitization and postoperative pain. Pregabalin (S-aminomethyl-5-methylhexaninacid) is a further development of gabapentin. Pregabalin has a fewer side-effects compared with gabapentin.

The purpose of this study is to compare the analgetic and anxiolytic effect of pregabalin and placebo used as premedication.

The hypothesis is that a single-dose pregabalin (150 mg postoperatively (p.o.)) gives significant better anxiolysis and analgesia than placebo.

The study is including patients undergoing surgery of the vertebral columna.
