Subarachnoid anesthesia is systematically applied for surgical procedures of hips due to its multiple advantages. Objective: To compare the effects of isobaric Bupivacaine versus the hypobaric one in subarachnoid anesthesia for hip osteosynthesis. Method: A total of 100 patients of both sexes were studied in "Dr. Carlos J. Finlay" Hospital. Fifty patients (Group A) received Bupivacaine (0.5%-3ml), and remainder (Group B) received Bupivacaine (0.25%-4 ml). We analyzed the following variables: sensitivity level, motor blockade degree, length, and quality of analgesia. Results: In 77% of patients there was a T10 sensitivity level, with a discrete predominance of T4 level in patients of A group. In all of them there was a total motor blockade and a good surgical analgesia. Length of analgesia was of 368.4±52.8 min in B group, and 276 ±29.69 min in A group. Conclusions: Hypobaric Bupivacaine was better than the isobaric one, since its use allow us to reach a lower sensitivity level, and a greater length of analgesia.
