  • Application of ultrasound in obstetric neuraxial anesthesia

    The traditional obstetric neuraxial anesthesia has no visual technical support. The success rate is closely related to the experience of the anesthesiologist, so there is a certain failure rate. With the widespread use of high-resolution portable ultrasound machines in recent years, a large number of clinical studies have upheld the feasibility and effectiveness of ultrasound in neuraxial anesthesia. The application of ultrasound in obstetric neuraxial anesthesia has obvious advantages compared with traditional methods of puncture. Ultrasound can accurately locate the intervertebral space, reduce the number of punctures, enhance the success rate of puncture, enhance the quality of obstetric anesthesia, and increase patients' satisfaction and comfort. This review shows the advantages and limitations of ultrasound in obstetric neuraxial anesthesia.

  • Comparison of inguinal approach versus classical pubic approach for obturator nerve block in transurethral resection of bladder tumors: a meta-analysis

    ObjectiveTo evaluate the clinical efficacy and safety of the inguinal approach versus classical pubic approach for obturator nerve block (ONB) in transurethral resection of bladder tumors (TUR-BT).MethodsDatabases including PubMed, The Cochrane Library, EMbase, Web of Science, WanFang Data, CNKI and VIP databases were electronically searched to identify randomized controlled trials using ONB in TUR-BT from inception to May 2020. Two reviewers independently screened literature, extracted data, and assessed risk bias of included studies. Meta-analysis was performed by using Stata 14.2 software.ResultsA total of 7 studies involving 474 patients were included. The meta-analysis results showed that there was no significant difference between inguinal approach and pubic approach in terms of the ONB success rate (RR=1.06, 95%CI 0.96 to 1.17, P=0.23), while the one-time success rate of puncture of inguinal approach was higher than that of pubic approach (RR=1.47, 95%CI 1.01 to 2.15, P=0.04). Compared with the pubic approach, the overall complications of inguinal approach were lower (RR=0.24, 95%CI 0.08 to 0.71, P=0.01). However, no significant difference was found between the two groups in terms of subcutaneous hematoma (RR=0.46, 95%CI 0.08 to 2.66, P=0.38).ConclusionsThe current evidence indicates that the success rate of one puncture of inguinal approach is higher than that of pubic approach, and the overall complications of the inguinal approach are much lower than that of the pubic approach. However, the above conclusions are still required to be verified through more high-quality studies due to the limited quantity and quality of included studies.
