Meta AnalysisThe analgesic efficacy of quadratus lumborum block in caesarean delivery: a meta-analysis and trial sequential analysis.
Quadratus lumborum block (QLB) has recently gained popularity for postoperative analgesia after cesarean delivery (CD) as it provides both visceral and somato-sensory blockade of the abdomen. Aim of this meta-analysis was to evaluate the analgesic potential of QLB after CD. ⋯ QLB significantly reduces opioid requirements in CD and may have analgesic effects lasting 24 h.

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.

Review Meta AnalysisThe efficacy and safety of prophylactic use of levosimendan on patients undergoing coronary artery bypass graft: a systematic review and meta-analysis.
Prophylactic use of levosimendan in cardiac surgery remains controversial and no meta-analysis has been done exclusively about that in patients undergoing coronary artery bypass graft (CABG) surgery. We conducted this systematic review and meta-analysis of levosimendan in CABG using PubMed, Embase, Scopus, and Cochrane Library (till April 20, 2018). ⋯ Subgroup analyses revealed that such a benefit was mainly observed in the isolated CABG, the preoperative administration, with-bolus and on-pump subgroups. More high-quality and well-designed prospective studies are needed to confirm or disprove our findings in future.

Review Meta Analysis Comparative StudyComparison of invasive and noninvasive blood hemoglobin measurement in the operating room: a systematic review and meta-analysis.
Noninvasive hemoglobin (Hb)-monitoring devices are new inventions in pulse oximeter systems that show hemoglobin levels continuously. The aim of this systematic review and meta-analysis was to evaluate the accuracy and precision of noninvasive versus standard central laboratory Hb measurements in the operating room. We systematically searched multiple databases. ⋯ A total of 28 studies on 2000 participants were included in the meta-analysis. Meta-analysis results of mean differences between noninvasive and the central laboratory Hb measurements in overall pooled random effects were - 0.27 (95% LoA (0.44, - 0.10); P value < 0.05). According to this meta-analysis, noninvasive hemoglobin measurement has acceptable accuracy in comparison with the standard invasive method.
