Randomized Controlled TrialComparison of Mill Suss™-guided radial artery catheterization with the long-axis in-plane ultrasound-guided method under general anesthesia: a randomized controlled trial.
Continuous arterial blood pressure measurement is an effective perioperative monitoring method in patients with high-risk comorbidities. Recently, ultrasound guidance has been reported to facilitate radial artery catheterization. A new device, Mill Suss™, has also been developed for visualization of the radial artery and superficial veins using near-infrared laser light. ⋯ The time required for successful radial artery catheterization was significantly shorter in Group M than in Group U. The number of attempts for successful cannulation was not statistically significantly different between the two groups. However, the results might be different among anesthesiologists well experienced in the ultrasound-guided method.

Review Randomized Controlled Trial Meta AnalysisVideolaryngoscopy for transesophageal echocardiography probe insertion: a systematic review and meta-analysis of randomized controlled trials.
Transesophageal echocardiography (TEE) is a well-established procedure, but serious complications may occur. This systematic review and meta-analysis assessed the utility of videolaryngoscopy-assisted technique in TEE probe insertion. We performed a systematic search in MEDLINE, EMBASE, CENTRAL, and ICTRP. ⋯ Videolaryngoscopy-assisted technique was also associated with smaller risk of complications (risk ratio [RR] 0.17; 95% CI 0.05, 0.62; low quality of evidence). There was no significant difference in time to probe insertion (MD - 8.57; 95% CI - 26.31, 9.16; very low quality of evidence). The use of videolaryngoscopy for TEE probe insertion is associated with a significant reduction in the number of attempts and complication rate.

Review Randomized Controlled Trial Meta AnalysisCould preprocedural ultrasound increase the first-pass success rate of neuraxial anesthesia in obstetrics? A systematic review and meta-analysis of randomized controlled trials.
Neuraxial anesthesia is a common practice in obstetrics. Evidence suggests that preprocedural ultrasound versus the conventional landmark location method accurately identifies a given intervertebral space and predicts the needle insertion depth required to reach the spinal canal. However, whether the preprocedural ultrasound examination improves the first-pass success (FPS) rate remains elusive. ⋯ There was no evidence of a reduction in failed punctures. We also noted that preprocedural ultrasound prolonged the identification time but not the procedure time. Thus, this systematic review provides evidence that preprocedural ultrasound does not improve the FPS rate of neuraxial anesthesia in patients who are easily palpated, although it increases the FPS rate in patients who are difficult to palpate.

Randomized Controlled TrialContinuous quadratus lumborum block and femoral nerve block for total hip arthroplasty: a randomized study.
Continuous femoral nerve block (FNB) has been effectively used after total hip arthroplasty (THA). Recently the anterior approach to quadratus lumborum block (QLB) has been shown to produce postoperative pain relief after THA. Continuous QLB would benefit from a catheter insertion site that is farther away from the surgical site compared with continuous FNB. In this randomized controlled study, we compared analgesic effects of the two techniques in patients undergoing THA. ⋯ Analgesic effects of continuous QLB were inferior to those of continuous FNB in patients undergoing THA under the current study condition.
