Television decreases intra-operative hypertensive events in cataract surgery: a randomized clinical trial
摘要
To compare the effects of television (TV) vs. music vs. control on hypertensive events and anxiety in cataract surgery.
MethodsA prospective, single-masked, randomized controlled trial of 476 adult cataract surgery patients at a surgical center in New York. Patients were randomized to either listen to classical music, view a home design and renovation program, or a control group. Blood pressure, heart rate, and anxiety levels (VAS-A) were measured before and 20 minutes post-intervention. Intra-operative hypertensive events (IOEs) were recorded.
ResultsOf 650 enrolled patients, 476 (27% exclusion) completed the study and a per-protocol analysis was used. In first-time cataract surgeries, the TV group had significantly fewer IOEs than controls (0 (0%) vs. 9 (10.3%), difference 10.3%; 95% CI, 3.9% to 16.7%; p = 0.003). Music did not show a significant IOE reduction vs. control (6 (6.4%) vs. 9 (10.3%), difference − 4.0%; 95% CI, -12.0% to 4.1%; p = 0.334). TV trended toward fewer IOEs than music but did not reach significance (0 (6.4%) vs. 6 (0.0%), difference 6.4%; 95% CI, 1.4% to 11.3%; p = 0.030, adjusted p = 0.025). Decreased VAS-A was reported between music vs. control (0.88 vs. 0.17, difference 0.71; 95% CI, 0.39 to 1.03), TV vs. control (0.84 vs. 0.17, difference 0.67; 95% CI, 0.35 to 1.02), music vs. TV (0.88 vs. 0.84, difference 0.04; 95% CI, -0.32 to 0.37).
ConclusionsViewing TV before surgery was associated with fewer IOEs in first-time cataract surgery patients. Music and TV were associated with lower pre-operative anxiety and might contribute to decreased IOEs that can be explored in future studies.
