   Objective To explore the application advantages of low-concentration ropivacaine for ultrasound-guided pericapsular nerve group（PENG）block combined with spinal-epidural anesthesia in hip joint surgery for frail patients．Methods Seventy-six frail patients undergoing hip surgery were randomly divided into two groups：Group A（38 cases）received PENG block combined with intraspinal anesthesia，while Group C（38 cases）received only intraspinal anesthesia．The numerical rating scale（NRS）pain scores of resting and active states were compared between the two groups at the time of entering the room（T0），placing the position（T1），6 hours after surgery（T2），12 hours after surgery（T3），and 24 hours after surgery（T4）．Postoperative non-steroidal drugs and opioids remedy times，muscle strength grading（MMT）of quadriceps femoris at 6 hours and 24 hours after operation，and the first time out of bed activity time，hospitalization time were also compared．Results The resting NRS pain scores at T1-T4 in Group A were 2（1，3），1（1，2），2（1，2）and 3（2，4），respectively，which were lower than 5（4，7），4（3，5），5（3，6）and 4（2，6）in Group C，and the difference was statistically significant（all P＜0.001）．The NRS pain scores at T1-T4 in Group A were 5（4，7），3（2，4），4（3，5）and 6（4，7），respectively，which were lower than 10（9，10），8（6，9），8（7，9）and 9（8，10）in Group C，and the difference was statistically significant（all P＜0.001）．The resting NRS pain score of Group A at T1-T4 was lower than that at T0（all P＜0.01）；the resting NRS pain score of Group C at T1-T4 was lower than that at T0（all P＜0.05）．The NRS pain scores at T1-T4 in Group A were lower than those at T0（all P＜0.001）；the NRS pain scores at T1 and T2 in Group C were lower than those at T0（all P＜0.01）．The number of postoperative non-steroidal drugs and additional opioids in group A（4［0，8］，2［0，3］）was lower than that in Group C（15［7，19］，5［3，7］），and the difference was statistically significant（all P＞0.001）．There was no significant difference in the MMT grade of the affected quadriceps femoris at 6 h and 24 h after operation，the first time of getting out of bed and the number of days of hospitalization between the two groups（P＞0.05）．Conclusions Low concentration ropivacaine PENG block can effectively reduce the postoperative pain of hip joint surgery in frail patients without affecting the postoperative lower extremity muscle strength．

Objective To evaluate the efficiency of postoperative analgesia with ropivacaine block after thoracoscopic-lapacoscopic esophagectomy (TLE). Methods Totally 60 patients with esophageal cancer underwent TLE were divided into two groups: observation group(n=30)with 0.25% ropivacaine hydrochloride solution 10 mL injection around incision before end of the operation; control group(n=30)without the treatment. The VAS and the plasma Cortisol concentration at 2 h、6 h、12 h、24 h、48 h after surgery were recorded. Results The VAS at 2 h、6 h、12 h after surgery in observation group was higher than that of the control group,but not at 24 h、48 h after surgery. The plasma Cortisol concentration in the observation group was higher than that of in the control at 12 hours postoperatively. Conclusion Ropivacaine block of incision is helpful to have analgesic effect within 12 hours after TLE.

Objective To compare the clinical effects of different concentrations of ropivacaine for postoperative analgesia after cesarean section. Methods 300 cases of pregnant women undergoing cesarean section in our hospital from March 2015 to March 2016 were selected and were randomly divided into group A, group B and group C with 100 cases in each group. The patients in group A were given 0.15% ropivacaine 1.5 mg/kg, 0.20% ropivacaine 1.5 mg/kg in group B and 0.25% ropivacaine 1.5 mg/kg in group C, and at the same time all the pregnant women were given analgesic pump assisting analgesia. The pain visual analogue scales (VAS) of the pregnant women were recorded at 6 hours, 12 hours, 24 hours and 36 hours after cesarean section and the number of times of analgesia pressing pump were also recorded. The satisfaction degree of analgesic effect and the TAP occurrence of adverse reactions of the patients were also recorded. Results The VAS scores of group B and group C were lower than that of group A(P<0.05). 24 hours after cesarean section, the VAS score of group C was lower than that of group B (P<0.05). Compared with group B and C, the number of times of analgesia pressing pump in group A were more but the analgesic effect of satisfaction was lower (P<0.05), and at the same time the number of times of analgesia pressing pump in group B were more than those in group C (P<0.05). No adverse reactions were found in the three groups. Conclusion The treatment of using of 0.25% of ropivacaine for muscle block for postoperative analgesia after cesarean section is effective and safe, which may be widely used in clinical practice.

Objective To observe the effectiveness and safety of ultrasound-guided subcostal transverses abdominis plane block with dexmedetomidine and low-concentration ropivacaine in elder vaginal hysterectomy. Methods Forty scheduled for vaginal hysterectomy (ASAⅠ～Ⅱ)were randomly assigned to 2 groups. All patients received spinal anesthesia, and ultrasound-guided subcostal transverses abdominis plane block then, Group Ⅰ: 0.5 μg/kg dexmedetomidine and 0.2% ropivacaine 20 mL for each side, and saline was used for Group Ⅱ. HR、MAP SpO₂ and NTI scale were recorded at the time points of pre-anesthesia(T₀), confirmation of anesthesia plane (T₁), beginning of surgery (T₂), pulling uterus (T₃), surgery end(T₄). Effect of dragging reaction, POCD and delirious and degree of comfort and degree of satisfaction of patients were valuated. Results The general condition did not differ between the two groups(P>0.05). Compared to Group Ⅰ, HR of Group Ⅱ at the time point of T3 was significant lower(P<0.05), number of patients with excellent dragging reaction of Group Ⅰ was significant higher (P<0.05)and patients of Group Ⅰ were more comfortable and satisfied than patinents of Group Ⅱ(P<0.05).

目的 对比观察罗哌卡因及布比卡因应用于患有妊娠期高血压的产妇行剖宫产时腰麻联合硬膜外麻醉的临床效果。方法 将103例择期行剖宫产手术的妊娠期高血压患者随机分为罗哌卡因组51例及布比卡因组52例分别采用对应药物进行麻醉,研究两组阻滞效果、心血管系统变化情况及不良反应发生情况。结果 两组间麻醉镇痛效果及优良率比较,差异没有统计学意义(P>0.05)。罗哌卡因组感觉及运动阻滞起效时间较布比卡因组长,运动阻滞恢复时间较布比卡因组短(P<0.05)。心血管系统变化情况比较,麻醉5min、10min时两组收缩压及平均动脉压均降低,但布比卡因组波动更大,两组间比较差异显著(P<0.05),心率及血氧饱和度比较无差异(P>0.05)。罗哌卡因组不良反应出现时间较布比卡因组晚,同时其不良反应发生率较布比卡因组低(χ²=4.1599,P<0.05)。结论 罗哌卡因及布比卡因在阻滞时间上略有差异,麻醉镇痛效果相当,但鉴于妊高症产妇本身心血管系统存在基础问题,运用罗哌卡因对心血管系统的影响较小,安全性更高,更值得推荐使用。
