Randomized Controlled Trial Comparative Study[Study of comparing dexmedetomidine and remifentanil for conscious sedation during radiofrequency ablation of hepatocellular carcinoma].
Objective: This study aimed to compare dexmedetomidine with remifentanil for conscious sedation in patients undergoing radiofrequency ablation of hepatocellular carcinoma. Methods: Sixty patients, who were aged 41 to 73 years with American Society of Anesthesiologists (ASA) physical status Ⅰ-Ⅱ, and scheduled for elective radiofrequency ablation of hepatocellular carcinoma under conscious sedation in National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, from January 2014 to June 2016, were allocated randomly to receive dexmedetomidine maintenance regimen(group D, n=30)or remifentanil maintenance regimen(group R, n=30)by random digital table. Subjects in group D received dexmedetomidine at a loading dose of 0.5 μg/kg over 10 min followed by 0.2-1.0 μg·kg(-1)·h(-1) infusion until Ramsay sedation scale reached 3-4. ⋯ Compared with group R, the incidence of intraoperative respiratory depression was significantly lower (23.3% vs 56.7%)and the incidence of inadequate anesthesia(20% vs 0) was significantly higher in group D(χ(2)=5.625, 4.630, both P<0.05). Conclusion: Both dexmedetomidine and remifentanil can be successfully used for conscious sedation in patients undergoing radiofrequency ablation of hepatocellular carcinoma. Remifentanil maintenance regimen provides better intraoperative analgesia and operative condition, while dexmedetomidine is superior to remifentanil in reducing intraoperative respiratory depression and postoperative pain.

Randomized Controlled Trial[Effects and safety of quadratus lumborum block in analgesia after hip arthroplasty].
Objective: To evaluate the efficacy of ultrasound guided quadratus lumborum block combined with non-steroidal anti-inflammatory drugs for postoperative analgesia in patients undergoing total hip arthroplasty. Methods: From January to June 2017, sixty American Society of Anesthesiologists (ASA) physical status Ⅰ to Ⅲ patients, aged 55-75 yr, scheduled for total hip arthroplasty, were randomly divided into control group(group N) and quadratus lumborum block (group R). Ultrasound guided quadratus lumborum block was implemented on the affected side at the end of operation. ⋯ The incidences of nausea and vomiting, pruritus in group R were lower than those in group N (χ(2)=5.192, 4.875, all P<0.01). The overall satisfaction scores in group R (3.7 ± 1.0 ) were higher than those (1.9±0.7) in the group N(t=7.841, P<0.01). Conclusion: The quadratus lumborum block combined with parecoxib sodium for multimodal analgesia after total hip arthroplasty is effective and provides satisfactory analgesia.

Randomized Controlled Trial[Application of continuous serratus plane block with patient-controlled analgesia on postoperation analgesia after thoracoscopic surgery].
Objective: To investigate the application of ultrasound-guided continuous serratus plane block with patient-controlled analgesia on postoperation analgesia after thoracoscopic surgery, and influence on postoperative rehabilitation. Methods: Sixty patients scheduled for thoracoscopic surgery were randomly divided into two groups. PCNA group (n=30) received ultrasound guided continuous serratus plane block with patient-controlled nerve analgesia, with continuous infusion of 0.2% ropivacaine and 30 ml of 0.3% ropivacaine for the first does. ⋯ And the time of out-of-bed activity, passage of gas by anus of the PCNA group were (20.0± 6.9)h, ( 16.0± 8.0)h, which was advanced more than PCIA group [(23.9± 7.1)h, (34.3± 13.2)h, t=-2.20, -6.47, all P<0.05]. Furthermore, PCNA group had better sleep quality from the 2nd night to the 4th night , and with lower adverse reactions (all P<0.05). Conclusion: The application of ultrasound-guided continuous serratus plane block after thoracoscopic surgery can reduce postoperative pain and enhance recovery after surgery.

[Surgical treatment of intractable odontoid fracture with atlantoaxial dislocation in children with spinal cord injury].
Objective: To discuss the surgical treatment and its effectiveness of odontoid fracture complicated with atlantoaxial dislocation in children with spinal cord injury. Methods: From January 2010 to December 2014, 10 cases of children under 14 years old, with intractable odontoid fracture with atlantoaxial dislocation were enrolled. The mean duration between injury and admission was 8.5 d (range 1-30 d). ⋯ At the last follow-up, out of 2 cases with Frankel C improved to D, and the other 8 cases were back to normal. Conclusions: Diagnosis of odontoid fracture complicated with atlantoaxial dislocation is usually delayed in children. One-stage posterior reduction and internal fixation or anterior release combined with posterior fixation is an effective and safe surgical procedure for such cases.

[Predictive value of GRACE discharge score for long-term out-of-hospital death in acute coronary syndrome after percutaneous coronary intervention].
Objective: To evaluate the prognostic value of Global Registry of Acute Coronary Events(GRACE) discharge score for long-term out-of-hospital death in acute coronary syndrome (ACS) after drug-eluting stents (DES) and with Dual-antiplatelet Therapy (DAPT). Methods: Our study was a prospective, observational, single center (Fuwai Hospital of China) study. A total of 6 431consecutive ACS patients underwent percutaneous coronary intervention(PCI)between January 2013 and December 2013 were involved. ⋯ The GRACE score showed predictive value in ACS patients after DESand with DAPT (area under the receiver operating characteristic curve (AUROC)=0.661; 95%CI 0.586-0.736, P<0.001). In subgroup analysis, GRACE score also showed predictive value both in unstable angina pectoris (UAP)(AUROC=0.660, 95%CI 0.576-0.744; P<0.001) and acute myocardial infarction(AMI)subgroup (AUROC=0.748, 95%CI 0.631-0.864; P=0.001). Conclusion: GRACE discharge score shows prognostic value for long-term out-of-hospital death in ACS patients undergoing PCI with DES and DAPT, and demonstrates good risk stratification of high and low-risk of death.
