Heart Rate Variability and Anxiety as Predictors of Emergence Agitation After Septorhinoplasty

Condition(s) studied

Study summary

This prospective observational study aims to evaluate whether preoperative heart rate variability (HRV) and anxiety are associated with, and can help predict, emergence agitation in adult patients undergoing elective septorhinoplasty under general anesthesia. Preoperative anxiety will be assessed using a visual analog scale (VAS) and the State-Trait Anxiety Inventory (STAI-1). Resting HRV will be recorded preoperatively using a chest-strap heart rate monitor and HRV metrics (e.g., SDNN, RMSSD, LF/HF) will be derived. Emergence agitation will be assessed in the post-anesthesia care unit (PACU) using the Richmond Agitation-Sedation Scale (RASS) during the early recovery period. Secondary observations will include early postoperative events such as postoperative nausea and vomiting (PONV) and laryngospasm. The study is planned to enroll approximately 100 participants.

Eligibility

Primary outcome measure(s)

• Incidence of Emergence Agitation — First 30 minutes after arrival to the PACU
  Emergence agitation will be assessed in the post-anesthesia care unit (PACU) using the Richmond Agitation-Sedation Scale (RASS). EA will be defined as a RASS score ≥ +1 at any assessment during the observation period.
