No results posted yet for this study

Summary

It is unknown whether different end-tidal carbon dioxide pressure levels have a clinically significant effect on bleeding and surgical field quality in septorhinoplasty, especially during controlled hypotension. Therefore, it was aimed to investigate the effect of ventilation strategy with controlled hypocapnia on intraoperative bleeding and surgical field quality for commonly practiced in septorhinoplasty.

Conditions

  • Anesthesia
  • Carbon Dioxide
  • Surgical Blood Loss

Interventions

DIAGNOSTIC_TEST

The amount of intraoperative bleeding

Total amount of intraoperative bleeding will be calculated in milliliters after the end of surgery.

DIAGNOSTIC_TEST

Quality of the intraoperative surgical field

Quality of the intraoperative surgical field will be measured on a grade of 0-10 (0-1. no bleeding, 2-3. mild bleeding, 4-5. Mild to moderate bleeding, 6-7. moderate bleeding, 8-9. moderate to severe bleeding, 10. Severe bleeding)

DIAGNOSTIC_TEST

Surgeon Satisfaction

Surgeon Satisfaction will be measured on a grade of 0-5 (1= very bad, 2= bad, 3= moderate, 4= good, 5= very good).

DIAGNOSTIC_TEST

Heart rate

From beginning of Anesthesia induction to the end of anesthesia (during perioperative period)

DIAGNOSTIC_TEST

Mean arterial pressure

From beginning of Anesthesia induction to the end of anesthesia (during perioperative period)

DIAGNOSTIC_TEST

Peripheral oxygen saturation

From beginning of Anesthesia induction to the end of anesthesia (during perioperative period)
