While dexmedetomidine may help facilitate earlier recovery, its impact on secondary outcomes remains suggestive rather than definitive due to low evidence certainty. Future large\u2010scale, multicenter randomized trials are required to confirm if these potential benefits translate into consistent clinical improvements.<\/jats:p>\n
