Venous Cannulation Pain to Guide Choice of Anesthetic Method

Abstract

The investigators have recently shown that pain associated with peripheral venous cannulation can be used to predict the risk of postoperative pain, where patients grading their pain associated with venous cannulation (VCP) above 2.0 VAS units had 3.4 times higher risk of moderate or severe postoperative pain after laparoscopic cholecystectomy and 1.7 times higher risk in a mixed group of patients and surgeries. The aim of this study is to investigate whether pain sensitivity measurements using VCP can be used to choose anesthesia treatment protocol with the aim to lower acute postoperative pain in those with high risk. In patients with low risk we aim to lower the amount of opioids given.
