Model of anesthesia care that combines anesthesiologists and registered nurses during cataract surgery
Abstract
PURPOSE: To determine the safety and practicality of a combined anesthesiologist and registered nurse model of anesthesia care in cataract surgery.
SETTING: Mayo Clinic, Rochester, Minnesota, USA.
DESIGN: Case series.
METHODS: This retrospective review comprised consecutive patients having phacoemulsification cataract surgery and peribulbar injection anesthesia combined with propofol intravenous sedation between August 1, 2004, and July 31, 2006. In all cases, anesthesiologist-supervised intravenous propofol sedation during injection anesthesia was followed by registered nurse observation for the remainder of the surgery. Outcome measures were the rate of subsequent anesthesiologist intervention, intraoperative complications, and associated risk factors. Logistic regression models were used to estimate risk for anesthesiologist intervention.
RESULTS: The study reviewed 3656 cases. There were no serious medical complications leading to postoperative hospitalization. Fifty-four cases (1.5%) required subsequent intraoperative anesthesiologist intervention. Evaluation of systolic hypertension (40 of 54 cases, 74%) was the most common reason for anesthesiologist intervention. There was no correlation between anesthesiologist intervention and patient age or sex (P=.77 and P=.41, respectively). The risk for anesthesiologist intervention increased 2.2-fold for every 1 unit increase in the American Society of Anesthesiologists Physical Status score (P=.007).
CONCLUSION: The…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
