Objective To observed the effect of dexmedetomidine as an adjunction with ropivacaine in supraclavicularbrachial plexus block. Methods 55 subjects with elective upper extremity operation were randomly divided into two groups: DEX group and control group. The drugs in DEX group was 30 μg dexmedetomidine (0.3 mL) + 0.5% ropivacaine, 20 mL in total. And the one in control group was normal saline (0.3 mL) +0.5% ropivacaine, 20 mL in total. After the operation of brachial plexus block, the value of sensory and motor block of brachial plexus and the onset time were evaluated and recorded according to the protocol. Vital signs and adverse events were monitored and recorded regularly during the operation.Postoperative vital signs, postoperative analgesia time, duration of brachial plexus sensationsensory and motion block, postoperative nausea and vomiting score, dosage of remedial analgesics and adverse events were assessed and recorded in 24 hours after surgery. Results In terms of sensory and motor onset time of brachial plexus, duration of sensory and motor block and postoperative analgesia, DEX group was longer than the control group, with statistical differences (P<0.05).There were no significant statistical differences between the two groups in postoperative vital signs, the amount of remedial analgesic drugs, postoperative nausea and vomiting scores, adverse events etc(P>0.05). Conclusion As an adjuvant, dexmedetomidine (30 μg) can accelerate the onset time of ropivacaine in the supraclavicular approach of brachial plexus block.It can also increase the postoperative analgesia time and sensory and motor block time of brachial plexus.With less impact on the vital signs of patients, the efficacy and clinical safety of dexmedetomidinecan be found in our study.

Objective To explore the effect of bilateral perineum nerve block anesthesia combined with comprehensive nursing in reducing the rate of perineum side cutting of primipara. Methods 110 primiparas who delivered vaginally in our hospital from July 2019 to December 2019 were selected as the research objects. According to the random number table method, they were divided into two groups, 55 in each group. The control group was given the routine nursing mode and local infiltration anesthesia. The observation group was given the comprehensive nursing mode and bilateral perineum nerve block anesthesia on the basis of the control group. The perineum side cutting status, perineum laceration, duration of labor, VAS score, Apgar score, compliance and nursing effect of the two groups were compared. Results Compared with the control group, the incidence of perineum side cutting was lower in the observation group than that in the control group (P<0.05).The first and second stages of labor were shorter in the observation group than the control group (P<0.05); compared with the control group, the VAS score, compliance and satisfaction index were better in the observation group than the control group (P<0.05), but there was no significant difference in neonatal asphyxia and postpartum hemorrhage (P>0.05). Conclusion Bilateral perineum nerve block anesthesia combined with comprehensive nursing may effectively reduce the incidence of perineum lateral incision of primipara, reduce the pain during delivery, shorten the labor process, improve the compliance and satisfaction of parturients, and has a high clinical value.
