Propofol and Sevoflurane Anesthesia in Colorectal Cancer Surgery: Incidence of Acute Kidney Injury

Propofol and Sevoflurane Anesthesia in Colorectal Cancer Surgery: Incidence of Acute Kidney Injury

The goal of this observational study is to compare anesthetic modalities (intravenous propofol anesthesia with sevoflurane gas anesthesia) in patients who underwent colorectal cancer resection surgery regarding the outcome of acute kidney injury.

The main questions it aims to answer are:

• is there a difference in acute kidney injury incidence in the two anesthetic modalities?
• is there a difference in plasma creatinine between the two anesthetic modalities?
• are there any patient characteristics or intraoperative factors that effect the incidence of acute kidney injury in either anesthetic modality?

The study will analyze data from the CAN clinical trial database. (Cancer and Anesthesia: Survival After Radical Surgery - a Comparison Between Propofol or Sevoflurane Anesthesia, NCT01975064)

Inclusion Criteria:

• colorectal surgery and participant in the CAN trial

Exclusion Criteria:

• missing blood samples
