Safety of Norepinephrine Administered Through Peripheral Venous Catheter

• Association between comorbidity, placement of catheter, duration of infusion and increased proportion of complications[ Time Frame: 0-72 hours ]
  Odds ratio of Treatment-Emergent Adverse Events in risk groups (ASA>2, placement of catheter distal to the antecubital or popliteal fossae, duration of infusion> 4 hours)

Norepinephrine is a drug that elevates the blood pressure. It is routinely administered through peripheral catheters during surgery. There is a risk of tissue damage in case of leakage of Norepinephrine from the catheter to the surrounding tissue. Another risk is irregular administration of Norepinephrine due to kinking of the peripheral catheter. This could lead to fluctuations in blood pressure. The primary aim of the study is to investigate complications from Norepinephrine administered in peripheral venous catheters. The secondary aim is to investigate if comorbidity, placement of the peripheral catheter or the duration of the infusion are associated with a higher rate of complications. 1000 patients will be included. Inclusion criteria: Patients who will undergo surgery with need for vasopressor support. Exclusion criteria: The patient has a central venous catheter, a peripherally inserted central venous catheter or lack of informed consent.
