Brief Summary:

Intraoperative intravenous fluid management practice varies greatly between anesthesiologists. Postoperative fluid based weight gain is associated with major morbidity. Postoperative respiratory complications are associated with increased morbidity, mortality and hospital costs. The literature shows conflicting data regarding intraoperative fluid resuscitation volume. No large-scale studies have focused on intraoperative fluid management and postoperative respiratory dysfunction.


Primary - Liberal intraoperative fluid resuscitation is associated with an increased risk of 30 day mortality Secondary - Liberal intraoperative fluid resuscitation is associated with increased likelihood of postoperative respiratory failure, pulmonary edema, reintubation, atelectasis, acute kidney injury and peri-extubation oxygen desaturation.

Time Perspective: Prospective
Official Title: Effect of Volume and Type of Fluid on Postoperative Incidence of Respiratory Complications and Outcome (CRC-Study)
Study Start Date : September 2013
Actual Primary Completion Date : March 2014
Actual Study Completion Date : March 2014

Primary Outcome Measures :
  1. Mortality [ Time Frame: within 30 days after surgery ]
    Mortality within 30 days of surgery

Secondary Outcome Measures :
  1. Postoperative pulmonary complications [ Time Frame: 3 days after surgery ]
    The incidence of a diagnosis of pneumonia, respiratory failure, atelectasis or pulmonary edema within 3 days after extubation in the operating room. Cases where these diagnoses were present on the day before surgery were not counted.

  2. Acute Kidney Injury [ Time Frame: within 48 hours of surgery ]
    A Creatinine increase of >0.3mg/dl or 50% from baseline (Creatinine value closest recorded to surgery but within 30 days of surgery) to maximum value measured within 48 hours postoperatively or an ICD-9 diagnosis of AKI within 7 days of surgery but not within 30 days prior to surgery

  3. Post-extubation oxygen desaturation [ Time Frame: within the first 10 minutes after extubation ]
    One or more minutes with a blood oxygen saturation below 90% during the first ten minutes after extubation
