Analgesia postoperatoria en cirugía mayor: ¿es hora de cambiar nuestros protocolos?

Evaluation of the risk/benefit ratio for the selection of the proper postoperative analgesia technique depends on the severity of dynamic pain and the potential adverse effects of analgesic drugs and techniques. Demonstrating the impact of postoperative analgesia on major outcomes such as surgical mortality, morbidity, or length of stay, can be difficult as these outcomes depend on multiple and heterogeneous factors. The effect of a specific type of analgesia on the entire surgical process should be investigated on the basis of patient-oriented outcomes, such as the quality of analgesia, adverse effects and postoperative comfort. Other areas in which postoperative analgesia could have a postoperative impact are those related to oncological recurrence and chronic postoperative pain.
