The study, published in the Dec. 2011 issue of The Spine Journal, looked at 2,494 charts detailing ambulatory spine procedures to determine the rate of adverse events when using conscious sedation in the ambulatory interventional spine setting. The rate and type of adverse events were compared for patients receiving local anesthesia alone or local anesthesia with conscious sedation.
The researchers found that immediate adverse events were seen in 5.12 percent of procedures with conscious sedation and 4.82 percent of procedures with only local anesthesia. The low rate of adverse events was maintained with both approaches when established protocols were followed, according to the report.
