Postoperative cognitive function and controlled hypotensive anesthesia in patients undergoing septoplasty

Peer review under responsibility of Egyptian Society of Anesthesiologists.

Figures & data

igure 1 Changes of heart rate in group (A): patients with controlled hypotensive technique and group (B): patients with normotensive technique throughout the operation. preHR = preoperative heart rate, int HR = intraoperative heart rate and postHR = postoperative heart rate.

igure 2 Changes of Oxygen saturation in group (A): patients with controlled hypotensive technique and group (B): patients with normotensive technique throughout the operation. Preoxygen = preoperative oxygen saturation, intoxygen = intraoperative oxygen saturation and postoxygen = postoperative oxygen saturation.

igure 3 Changes of blood pressure in group (A): patients with controlled hypotensive technique and group (B): patients with normotensive technique throughout the operation. preBP = preoperative blood pressure, int BP = intraoperative blood pressure and postBP = postoperative blood pressure.

Table

Score	Definition
0	No bleeding
1	Mild bleeding	No need of blood aspiration
2	Mild bleeding	Occasional aspiration necessary – Clear surgical field
3	Moderate bleeding	Frequent aspiration necessary. Bleeding closes surgical field a few seconds following aspiration
4	Moderate bleeding	Frequent aspiration necessary. Bleeding closes surgical field right after aspiration
5	Excessive bleeding	Continuous aspiration necessary. Bleeding appears faster than aspiration. Surgical field is closed and surgery is not possible
