Assessment of Patient Anxiety, Sedation Requirements, and Intraoperative Stability during Ophthalmic Surgery under Local Anesthesia: A Prospective Cohort Study at S. M. College
Background: Preoperative anxiety could affect the need for sedation and intraoperative stability during ophthalmic surgery under local anesthesia.
Objectives:To evaluate anxiety, sedation need and intraoperative stability in patients undergoing ophthalmic surgery under local anesthesia.
Methods: It was a prospective cohort study of 120 adult patients undergoing elective ophthalmic surgery under local anesthesia at S. M. College and Hospital, Uttar Pradesh, from 2008 to 2009. Anxiety grade, sedation use, vital parameters, patient cooperation and adverse events were documented.
Results: Sixty-nine patients (57.5%) had clinically significant anxiety. Fifty-four patients (45.0%) required sedation, which rose with the severity of the anxiety (17.4% in mild, 55.8% in moderate, and 94.1% in severe anxiety, p<0.001). Moderate/severe anxiety group had higher HR and SBP during surgery, but similar oxygen saturation. Good cooperation was seen in 85 patients (70.8%) and intraoperative stability was maintained in 92 patients (76.7%). Forty-seven patients (87.0%) required only sedation.
Conclusions: Preoperative anxiety was common and associated with sedation needs and less favourable cardiovascular trends. Anxiety assessment and selective sedation may enhance peri-operative care.
