About

Patients undergoing major surgery are exposed to extensive damage of tissues, which induces widespread activation of the inflammatory system, called 'systemic inflammatory response syndrome' (SIRS).This activation of the inflammatory system may induce instability of the heart and respiration in the postoperative period. The degree of physiologic response to postoperative SIRS as well as the degree of postoperative pain differ between patients. Therefore, patients undergoing anesthesia and major surgery are treated in a 'post anesthesia care unit' (PACU) after end of surgery.Admittance to a PACU is expensive. The time patients need to stay in a PACU after major surgery has not been extensively studied, and more appropriate tools for prediction of length of stay are needed.

The main aim of this study is to assess whether clinical observations, inflammatory biomarkers or genetic markers may aid in the prediction of physiological instability and/or pain after major surgery. Such predictors would help clinicians planning the length of PACU-stays.

Major abdominal surgery

Description:

Patients undergoing major abdominal surgery (laparotomy). Surgical procedures considered for inclusion include, but are not restricted to, procedures such as gastrectomy, pancreatic surgery, liver resection, open prostatectomy, colonic surgery, radical cystectomy with ileal conduit, open nephrectomy and vascular abdominal aortic surgery.
