Processed EEG Monitoring During Controlled Hypotension in Patients Undergoing Rhinoplasty
Observational Evaluation of the Relationship Between Intraoperative Processed EEG Monitoring,Surgical Bleeding and Recovery Quality in Patients Undergoing Rhinoplasty Under Controlled Hypotension

Szczegółowy opis
Controlled hypotension is commonly used during rhinoplasty to improve surgical field visibility and reduce bleeding. However, the adequacy and safety of controlled hypotension should not be evaluated only by hemodynamic variables. Processed EEG monitoring may provide additional information about hypnotic depth and the probability of response to nociceptive stimulation.
In this prospective observational study, adult patients undergoing elective rhinoplasty under general anesthesia were monitored with standard ASA monitoring and processed EEG monitoring. Total intravenous anesthesia was maintained with propofol and remifentanil. Esmolol infusion was used as part of the controlled hypotension strategy. Intraoperative qCON and qNOX values, hemodynamic parameters, surgical bleeding scores, anesthetic drug consumption, extubation time, time to reach Aldrete score ≥9, and early postoperative cognitive recovery were recorded.
The primary objective is to evaluate the intraoperative course of qCON and qNOX values during controlled hypotension. Secondary objectives are to assess the relationship of processed EEG parameters with recovery quality, early postoperative cognitive status, anesthetic drug consumption, and surgical field bleeding.

|
Intraoperative qCON and qNOX values during controlled hypotension
Ramy czasowe: From baseline before anesthesia induction until the end of surgery, up to approximately 150 minutes intraoperatively.
|
qCON and qNOX values obtained by processed EEG monitoring will be recorded at predefined intraoperative time points.
qCON will be used as an index of hypnotic depth, and qNOX will be used as an index of the probability of response to nociceptive stimulation.
|
From baseline before anesthesia induction until the end of surgery, up to approximately 150 minutes intraoperatively.

Surgical field bleeding will be evaluated using the Boezaart surgical field bleeding score at predefined intraoperative time points.
|
Intraoperatively, from surgical incision until the end of surgery.

|
Extubation time
Ramy czasowe: At the end of surgery
|
Time from discontinuation of anesthetic agents to extubation will be recorded in minutes
|
At the end of surgery
|
|
Time to reach Aldrete score ≥9
Ramy czasowe: Early postoperative recovery period, immediately after extubation.
|
The time required to reach an Aldrete recovery score of 9 or higher will be recorded in minutes
|
Early postoperative recovery period, immediately after extubation.
|
|
Early postoperative delirium assessed by the Nursing Delirium Screening Scale
Ramy czasowe: At admission to the post-anesthesia care unit
|
Patients were assessed for early postoperative delirium in the post-anesthesia care unit using the Nursing Delirium Screening Scale (Nu-DESC).
The Nu-DESC ranges from 0 to 10, with higher scores indicating more severe delirium symptoms.
|
At admission to the post-anesthesia care unit
|
|
Total anesthetic drug consumption
Ramy czasowe: From anesthesia induction until the end of surgery
|
Total intraoperative consumption of propofol, remifentanil, and esmolol will be recorded
|
From anesthesia induction until the end of surgery
