CRNA : the clinical forum for nurse anesthetists
-
The purpose of this study was to determine the correlation between patient controlled analgesia and continuous epidural analgesia after total knee or total hip replacement on the length of hospital stay. Stress responses to postoperative pain, including decreased mobility, compromised respiratory function, increased catecholamine release, and hypercoagulation, may adversely affect patient recovery, thus lengthening hospital stay. A retrospective chart review of 127 adult, American Society of Anesthesiology (ASA) I, II, or III, patients who had undergone total knee arthroplasty (TKA) or total hip replacement (THR) was obtained. ⋯ These findings were not statistically significant at P = 0.054. LOS did not correlate with age, weight, height, type or surgery, or the ASA classification. Further research into the effectiveness of continuous infusion of epidural bupivacaine and epidural morphine and their impact on LOS may be warranted.
