Use of perioperative hydroxyethyl starch 6% and albumin 5% in elective joint arthroplasty and association with adverse outcomes: a retrospective population based analysis.

OBJECTIVE

To determine whether the perioperative use of hydroxyethyl starch 6% and albumin 5% in elective joint arthroplasties are associated with an increased risk for perioperative complications.

DESIGN

Retrospective cohort study of population based data between 2006 and 2013.

SETTING

Data from 510 different hospitals across the United States participating in the Premier Perspective database.

PARTICIPANTS

1,051,441 patients undergoing elective total hip and knee arthroplasties.

EXPOSURES

Perioperative fluid resuscitation with hydroxyethyl starch 6% or albumin 5%, or neither.

MAIN OUTCOME MEASURES

Acute renal failure and thromboembolic, cardiac, and pulmonary complications.

RESULTS

Compared with patients who received neither colloid, perioperative fluid resuscitation with hydroxyethyl starch 6% or albumin 5% was associated with an increased risk of acute renal failure (odds ratios 1.23 (95% confidence interval 1.13 to 1.34) and 1.56 (1.36 to 1.78), respectively) and most other complications. A recent decrease in hydroxyethyl starch 6% use was noted, whereas that of albumin 5% increased.

CONCLUSIONS

Similar to studies in critically ill patients, we showed that use of hydroxyethyl starch 6% was associated with an increased risk of acute renal failure and other complications in the elective perioperative orthopedic setting. This increased risk also applied to albumin 5%. These findings raise questions regarding the widespread use of these colloids in elective joint arthroplasty procedures.
