Abstract
Over the last few years, there has been increased emphasis on early discharge of patients following carotid endarterectomy in the United States. Recent studies have shown that short-stay hospitalization for carotid endarterectomy may be safe and cost-effective. However, this is not always possible because of reasons that are not clearly delineated. In order to optimize the early discharge of patients following carotid endarterectomy, an analysis of the causes of delayed discharges was performed in the present series. Since hemodynamic instability has been shown to be the most frequent complication following carotid endarterectomy, the authors investigated whether it was an important factor preventing early postoperative discharge. This study reviewed the data of 100 consecutive patients admitted for elective carotid endarterectomy. The incidence of post-carotid endarterectomy hemodynamic instability was 37% (n = 37), with hypertension occurring in 25 patients (68%) and hypotension occurring in 12 patients (32%). Hemodynamic instability tended to occur with the use of general anesthesia as compared with regional anesthesia. Hemodynamic instability did not correlate with pre-existent history of hypertension, nor with the type of drug used when general anesthesia was applied. All the patients were successfully treated either in the recovery room or in a monitored area. The average total length of stay was 1.65 days with 79% of the patients being discharged on the first postoperative day and 21% having delayed discharge ranging from 2 to 15 days (mean 4 days). The main reasons for delayed discharges were cardiac and urinary tract complications. Blood pressure instability accounted for only 2% of cases. Thus, these data show that hemodynamic instability does not significantly affect early discharge.
