简要总结
the proposed RCT comparing the efficacy of two different volumes of 0.75% hyperbaric ropivacaine for spinal anaesthesia in infraumbilical surgeries is innovative. the primary and secondary outcomes of the study are expected to add greatly to the understanding of the ideal drug volume of inj ropivacaine. the central hypothesis of the proposed research is that the quality of spinal anaesthesia in terms of duration oof analgesia;and onset and offset times of sensory-motor blockade will be better with 2.4cc than 2cc of 0.75% hyperbaric ropivacaine during infraumbilical surgeries under spinal anaesthesia.
