Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.
Primary outcome(s):
1. Perioperative complications (immediate and mediated intraoperative and postoperative). Measurement time: 30 days after surgery. For this, they will be measured as: Intraoperative (Complications that arise from the beginning of the anesthetic procedures until the patient,is transferred to the ICU after the operation), Immediate postoperative (Complications that occur from the moment the patient arrives at the ICU until the first 72 hours after the surgical intervention), Postoperative mediations (Complications that occur from 72 hours after the surgery and until the patient is discharged from hospital) and Late postoperative (Complications that occur from hospital discharge up to 30 days after the surgical procedure)
2. Stay in the Intensive Care Unit (Time, measured in hours, from the entrance to the Intensive Care Unit (ICU) until the exit from the ICU). Measurement time: Upon discharge from the ICU
3. Hospital stay (Time, measured in days, from the date of entry to the ward until hospital discharge). Measurement time: at hospital discharge
Key secondary outcomes:
1. Adherence to the ERAS protocol (If when 75% (15 of 21) of the recommended actions in the study group are met). Measurement time: 72 hours after surgery.
2. Orotracheal extubation time (Time elapsed, in hours, from the end of the surgical intervention until the orotracheal extubation). Measurement time: At orotracheal extubation
3. Enteral nutrition time (Time elapsed, in hours, from the end of the surgical intervention until the oral feeding route is established). Time: at the time of establishing oral feeding.
4. Total intraoperative-BHTI and postoperative-BHTP water balance (Amount of volume, quantified in milliliters, to be administered to the patient during the intraoperative and postoperative periods). Measurement time: at the end of the intraoperative and postoperative periods
5. Time of postoperative mobilization-TMP (Time elapsed, in hours, from the end of the surgical intervention until the patient is seated). Measuring time: when the patient sits
6. Postoperative analgesia (Intensity of pain, evaluated verbally, according to visual analog scale (VAS) from zero to ten points). Measurement time: after the patient has been extubated, on an hourly basis, in the first three hours, at six hours, 12 hours, 24, 48 and 72 hours.
7. Opioid consumption (Total dose of opioids (mg) intravenously, which is needed in each patient to achieve adequate analgesia during the perioperative period). Measurement time: at the end of the perioperative period
8. Inotropic drug use (Yes, No. As required inotropic drugs to achieve hemodynamic stability). Measurement time: Upon discharge from the ICU
9. Early hospital readmission (Yes, No. As required by a re-entry of the patient after hospital discharge, for any reason). Measurement time: 30 days after surgery.
10. Level of satisfaction (High if the affirmative answers to the questions are between 90 and 100%, Quite satisfied if the affirmative answers to the questions are between 80 and 89%, Satisfied if the affirmative answers to the questions are between 70 and 79% and, not satisfied if the affirmative answers to the questions are less than 70%). Measurement time: 30 days after surgery.
