E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the effect of Opioid-Free Anesthesia on the ratio arterial oxygen pressure/Fraction of inspired oxygen (PaO2/FiO2) during the first 6 postoperative hours compared to conventional anesthesia. |
Evaluar el efecto de la Anestesia Libre de Opioides en el cociente Presión arterial de oxígeno/Fracción inspirada de oxígeno (PaO2/FiO2) durante las primeras 6 horas postoperatorias en comparación con la anestesia convencional. |
|
E.2.2 | Secondary objectives of the trial |
- Assess the effects on ventilation by measuring the partial pressure of oxygen (PCO2). - Evaluate hemodynamic stability, by comparing blood pressure (BP) and basal heart rate, after intubation, after surgical stimulation and upon arrival at the post-anesthesia resuscitation unit (PACU). - Evaluate pain control and consumption of postoperative morphic. - Evaluate postoperative nausea and vomiting. - Evaluate post-surgical recovery and length of hospital stay. - Assess costs |
• Evaluar los efectos sobre la ventilación mediante la medición de la presión parcial de oxígeno (PCO2). • Evaluar la estabilidad hemodinámica, mediante la comparación entre Tensión arterial (TA) y frecuencia cardiaca basal, tras la intubación, tras el estímulo quirúrgico y a su llegada a la unidad de reanimación postanestésica (URPA). • Evaluar el control del dolor y consumo de mórfico postoperatorio. • Evaluar las nauseas y vómitos postoperatorios. • Evaluar la recuperación postquirúrgica y la duración del ingreso hospitalario. • Evaluar los costes |
