ABSTRACT

One of the main targets of pre-anesthetic medication is to relief anxiety of the patient who will be taken to a surgical procedure. Actually most of ophthalmic surgical procedures are done under sedation and regional or topic anesthesia. One of the drugs that provides ansiolysis is Dexmedetomidine, an alpha 2 agonist–adrenergic, which has not been well studied. in anesthesic management. Publications just include its effects to produce sedation and analgesia for no more than 24 hours on patients in the Intensive Care Unit only. On this study we take advantage of these effects as medication and maintenance anesthesic on patients who were programmed for ambulatory ophthalmic surgery (cataract) under regional anesthesia. Material and methods: We present the experience of an experimental, longitudinal, comparative, prospective, opened study of these surgeries with impregnation of dexmedetomidine to 1 µg/kg and maintenance with 0.3 µg/kg in group A and 0.5 µg/kg in group B at the Regional Hospital «General Ignacio Zaragoza», including two groups of adult patients ASA I, II, III, between 50 and 80 years old, both sex, cardiovascular changes like cardiac rate medium arterial pressure and oxygen saturation, Ramsay sedation Scale, and analogy visual scale, were analyzed during pre, trans and post anesthetic time. Statistical analyze: Chi square, and Mann-Whitney U tests were used. Results: no significative statistical differences were found by this study, except the Ramsay sedation scale that was increased in group B, showing important differences at ending of impregnation and beginning of infusion. Conclusions: This research determined the safety and efficacy of two small-dose infusions of dexmedetomidine on the surgery room as surch as a unique new alternative for ambulatory ophthalmic surgeries under regional anesthesia by evaluating sedation, analgesia, cognition, and cardio respiratory function. We found evidence that sustained our hypothesis and no adverse effects were found.
