Brief Summary:
In order to improve the postoperative period (namely pain control), several drugs can be used. For instance, ketamine is a general anesthetic that holds strong analgesic properties, yet also owns undesirable effects, in which hallucination phenomena is one the most common indicator. However, slight information is available about the real implication in the quality of the recovery on the use of ketamine for postoperative pain treatment. The quality of the recovery includes several health conditions, such as pain, physical comfort, physical independence, psychological support and emotional state. In recent years, investigations in this field has been attracted the attention by the health professionals, since is an indicator of the quality of post-operative care. To evaluate these parameters, questionnaires have been developed, in which the Portuguese version of Quality of Recovery 15 (QoR-15) is include. This questionnaire evaluates five psychometric dimensions. Therefore, the present study has the main goal, the evaluation of the effect of using ketamine in laparoscopic surgery and the quality of the recovery using the QoR-15 questionnaire.
