Analgesic comparison of TAP block with bupivacaine and dexmedetomidine, versus tramadol and metamizole in OVH.

Abstract

Introduction. Currently, echo-guided nerve blocks are performed for multimodal pain management; this is a regional anesthesia tool that is of utmost importance in clinical and surgical practice. What is sought is to desensitize certain sections of the animal organism, the use of local anesthetics provides analgesia and reduces the anesthetic demand of patients. Therefore, what we seek is to avoid any type of suffering as a result of pain and as professionals we must guarantee that Our patients do not experience this sensation. Objective. The objective of the present investigation was to determine the analgesic effect of TAP blockade with bupivacaine and dexmedetomidine, compared to tramadol and metamizole in OVH. Methodology. In this research work we evaluate whether the transversus abdominis block (TAP) with bupivacaine and dexmedetomidine is more efficient when controlling pain, compared to the administration of metamizole sodium and intravenous tramadol. The patients were previously selected and it was taken into account that they weigh between 5-10 kg, the patients were listed in two groups and the treatments were assigned randomly. The TAP block was performed bilaterally using the 2019 Chinese-made Chison ECO6 Color Doppler Ultrasound, for which a Chinese-made 10 MHz Chison linear transducer was used. To deposit bupivacaine (2.5 mg/kg) combined with dexmedetomidine (100 ug/kg), German-made Stimuplex® echogenic needles from B-Braun were used. The group of individuals who did not undergo the block were medicated for postoperative pain intravenously with tramadol (6mg/kg) plus metamizole sodium (40mg/kg). The degree of pain was evaluated using the Glasgow Pain Scale during a 12-hour period in patients undergoing olivaryhysterectomy. Results. The perception of pain of the two experimental groups at 12 hours after surgery showed that there were no significant statistical differences (p>0.005) between the analgesia provided by the IV route, compared to performing the nerve block of the TAP branch. Therefore, the proposed hypothesis is null. Conclusion. It is concluded that there were no significant statistical differences in the perception of pain in the two experimental groups, therefore performing peripheral nerve branch blocks is safe and feasible, since it helps in the multimodal management of pain and in this way we improve the well-being of our patients, it should be noted that it is a widely used technique in human medicine and today the implementation of this technique in veterinary medicine is feasible and shows great results.
