Oxygen delivery as a factor in the development of fatal postoperative complications after oesophagectomy.

BACKGROUND: This study was designed to assess the impact of oxygen transport variables on outcome in 115 patients undergoing elective surgery for oesophageal carcinoma. METHODS: Haemodynamic parameters were determined using a Swan-Ganz catheter in all patients on the day before operation, 6 h after operation, and daily for the first 4 days after operation. RESULTS: Oxygen delivery and consumption at 6 h were significantly higher in survivors than in non-survivors. However, oxygen delivery and consumption in both groups did not differ significantly after postoperative day 1. Of 17 patients with oxygen delivery levels lower than 445 ml min-1 m-2 at 6 h, eight died in hospital. Oxygen delivery in patients who developed either an anastomotic leak or severe pneumonia was significantly lower 6 h after surgery. Lower levels of oxygen delivery preceded postoperative complications. CONCLUSION: Oxygen delivery 6 h after oesophagectomy correlates with postoperative complications and may be a determinant of hospital mortality.[1]
