Abstract:
Objective To observe the effect of subarachnoid block with 0.5% bupivacaine at different temperatures during cesarean section.Methods 100 cases of elective cesarean section were randomly divided into room temperature group and heating group,50 cases in each group.Room temperature group: bupivacaine hydrochloride injection and glucose injection equilibrated group in a constant temperature thermostatic bath of 24 degrees thermostatic bath heating for above 30 min.Heating group: bupivacaine hydrochloride injection and glucose injection heated in the constant temperature thermostatic bath of 37 degrees thermostatic bath heatingfor above 30 min.Anesthesia was injected into the subarachnoid space at different temperatures to observe the anesthetic effect.Results The anesthesia increased rapidly, and the analgesia and muscle relaxation effects were better in the heating group than room temperature group, but the heating group had hypotension rate was higher than the room temperature group (36.0% vs.16.0%).There was no obvious difference between the incidence of adverse reactions such as nausea and vomiting in both groups.Conclusion Different temperatures of bupivacaine can be used safely for section anesthesia.The anesthesia effect of the heateding bupivacaine is faster, the anesthesia level is higher, the anesthesic and muscle relaxant effect is better.Bupivacaine at room temperature has relatively small effect on hemodynamics.
