The aim of the present study is to investigate the effect of intravenous anesthetics versus the administration of volatile anesthetics on stress and pain levels during autologous fat transfer for breast reconstruction in a Day Care Center.
The sample of the study will be patients who will have Autologous Fat Transfer for Breast Reconstruction.
Patients will be divided into 2 groups. The TIVA group (N = 23) will be administrated intravenous anesthesia (propofol-remifentanil), while the DES group (N = 23) volatile anesthetics (desflurane-remifentanil).
Specifically, the TIVA group will include patients over 50 years of age with high risk of nausea / vomiting and postoperative delirium, as well as suspicion of malignant hyperthermia. Patients with cardiac and respiratory problems will be included in the DES group.
The following data will be collected in the Data Sheet: Patient Demographics (Gender, Age), Body Mass Index (Body Height- Body Weight). Simultaneously, the pain levels will be evaluated by VAS Optical Analogue Scale of VAS 0-10 in PACU, preoperatively and postoperatively, and perioperative pain levels will be assessed with CPOT scale (values 0-8).
Stress levels will be evaluated with 3 NAS questions: a. How sad do you feel right now? b. How anxious do you feel right now? and c. How optimistic do you feel right now?. The 3 NAS questions will also be given preoperatively and postoperatively to the ward. The sedation levels will be assessed by RASS scale (values +4 to -5) and the Bispectral Index (BIS). The level of patient's awareness will be assessed by GCS Scale (3 (indicating deep unconsciousness) and either 14 (original scale) or 15 (more widely used modified or revised scale)).
The presence or absence of nausea / vomiting and the appearance of immediate postoperative complications will be examined. Finally, post-operative stress will be examined with stress biomarkers, salivary ACTH hormone and salivary cortisol hormone.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Total intravenous anesthesia | Experimental | The patients will recieve intravenous anesthesia (propofol-remifentanyl) Recommended dosage: Propofol: Induction dosage 1,5-2,5 mg/kg Remifentanyl: Induction dosage 0,5-1μg/min The preservation dosage will depend from patients' body weight, body height and BMI |
|
| volatile anesthesia | Experimental | The patients will recieve volatile anesthesia (desflurane-remifentanyl) Recommended dosage: Desflurane dosage 6-7 MAC Remifentanyl: Induction dosage 0,5-1μg/min The preservation dosage will depend from patients' body weight, body height and BMI |

Evaluating perioperative stress levels between the two protocols with scale, such as the self-experienced questions (range0-10, (with a score of 0 = None and 10 = Completely) ) how sad are you feeling?in two phases: a. preoperatively, b) in PACU |
| 1 day during hospitalization |
| Evaluating Patients' Sedation | Evaluation with Richmond Agitation-Sedation Scale (RASS scale, range +4 to -5, (with a score of -5 = unarousable and +4 = violent, immediate danger for the staff) ). | Perioperatively |
| Evaluating Patients' Sedation | Evaluation with Bispectral index (BIS, range 0-100). A BIS score quantifies changes in the electrophysiologic state of the brain during anesthesia. In patients who are awake, a typical BIS score is 90 to 100. Complete suppression of cortical activity results in a BIS score of 0, known as a flat line. Lower numbers indicate a higher hypnotic effect. Overall, a BIS value below 60 is associated with a low probability of response to commands. | Perioperatively |
