Comparison of the effect of preoperative multimedia video information on preoperative anxiety in patients undergoing procedures under central neuraxial block: a prospective, single-blind, randomized controlled study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background and Aims: Preoperative anxiety is one of the most common perioperative complications observed in patients undergoing surgery. The use of State Trait Anxiety Inventory (STAI) and Visual Analogue Scale (VAS-A) scores for anxiety has been demonstrated to reduce the preoperative anxiety levels. We evaluated the effect of preoperative multimedia video information on preoperative anxiety and haemodynamic parameters in patients undergoing procedures under central neuraxial block (CNB). Materials and Methods: Sixty patients of either sex, aged 18-60 years undergoing elective surgeries under CNB were randomized into Group V (video) and Group NV (non-video). The primary outcomes included STAI score and VAS-A score assessed one hour prior to surgery. The secondary outcomes involved haemodynamic parameters before performing CNB and, patient's cooperation for CNB assessed by three-point scoring system. Results: Demographic parameters were comparable in both groups. The HR, SBP, DBP and MAP showed a significant increase from their baseline values before surgery in Group NV as compared to Group V (p<0.001). In Group V, STAI scores decreased significantly (p<0.001), while Group NV showed a significant increase (p<0.001). VAS-A scores for anxiety decreased in Group V and increased in Group NV before surgery (p<0.001). Group V demonstrated higher cooperation scores (score ≥2). Conclusion: Preoperative multimedia information was associated with reduced anxiety, better haemodynamic stability, and improved patient cooperation. Employing multimedia information in the form of video may prove beneficial for allaying preoperative anxiety in adults undergoing surgery under CNB.
