Study objective The erector spinae plane block (ESPB) is a newly defined regional anesthesia technique first introduced in 2016. The aim of this study is to determine its analgesic efficacy compared with non-block care and thoracic paravertebral block (TPVB). Design We systematically searched PubMed, Web of Science citation index, Embase, the Cochrane Library, Google Scholar, and ClinicalTrials.gov register searched up to March 2020. We conducted a meta-analysis of randomized controlled trials (RCTs) that compared an ESPB to non-block care or TPVB for postoperative analgesia in breast and thoracic surgery patients. Primary outcome was 24-hour postoperative opioid consumption. Risk of bias was assessed using Cochrane methodology. Results 14 RCTs that comprised 1018 patients were included. Seven trials involved thoracic surgery patients and seven included breast surgery patients. Meta-analysis revealed that ESPB significantly reduced 24-hour opioid consumption compared with the non-block groups (-10.5 mg; 95% CI -16.49 to -3.81; p = 0.002; I2 = 99%). Similarly, the finding was consistent in subgroup analysis between the breast surgery (-7.75 mg; 95%CI -13.98 to -1.51; p = 0.01; I2 = 97%) and thoracic surgery (-14.81 mg; 95%CI -21.18 to -8.44; p less then 0.001; I2 = 96%) subgroups. The ESPB significantly reduced pain scores at rest or movement at various time points postoperatively compared with non-block group, and reduced the rate of postoperative nausea and vomiting (OR 0.48; 95%CI 0.27 to 0.86; p = 0.01; I2 = 0%). In contrast, there were no significative differences reported in any of the outcomes for ESPB versus TPVB strata. Conclusions ESPB improved analgesic efficacy in breast and thoracic surgery patients compared with non-block care. Furthermore, current literature supported the ESPB offered comparable analgesic efficacy to a TPVB.Study objective Comparison of ultrasound-guided lumbar plexus block (LPB) and suprainguinal fascia iliaca block (SIFIB) in patients undergoing total hip arthroplasty (THA). Design Randomized equivalence trial. Setting University Hospital. Patients Sixty patients undergoing primary THA. Interventions Patients were randomly allocated to receive ultrasound-guided LPB (n = 30) or SIFIB (n = 30). The local anesthetic agent (40 mL of levobupivacaine 0.25% with epinephrine 5 μg/mL) and block adjuvant (4 mg of intravenous dexamethasone) were identical in all subjects. Postoperatively, all patients received patient-controlled intravenous analgesia (morphine) as well as acetaminophen and ketoprofen during 48 h. Measurements A blinded investigator recorded morphine consumption at 24 and 48 h as well as time to first morphine request, pain scores at 3, 6, 12, 24 and 48 h, incidence of adverse events, time to readiness for discharge, and length of hospital stay. The blinded investigator also carried out sensorimotor blockfor discharge as well as decreased hospital stay.Objective To investigate the effect of copper impregnated wound dressings on the surgical site infection (SSI) rate following caesarean section (CS). Design Single centre double blind randomised controlled trial. Participants Women aged 18 years or over who had a CS. Interventions All women were randomised to receive either a copper-oxide impregnated wound dressing (study group) or a non-copper wound dressing (control group). Main outcome measures The primary study outcome was the incidence of SSI within a 30-day period from CS, assessed via a telephone questionnaire. Secondary outcomes were length of hospital stay, and readmission rate. Results 324 women were enrolled in the study of whom 159 were randomised to the study group and 165 to the control group. The follow up rate was 97.5%. selleck chemicals llc A total of 78 women (24.1%) developed an SSI within 30 days following CS; 29 (18.2%) in the study group and 49 (29.7%) controls (P = 0.037, relative risk reduction (RRR) of 38.7%). The incidence of superficial/deep SSI was not significantly different (24.2% vs. 17.6%, P = 0.257), however a significant relative risk reduction of 80.3% for Organ/Space SSI was observed in the study group (12.7% vs. 2.5%, P = 0.002). Length of hospital stay, and readmission rate did not vary significantly between groups. Conclusions This is the first study to demonstrate a significant reduction in SSI rates following CS with the use of copper impregnated wound dressings. The high SSI rate confirms the importance of new strategies to reduce the infection rate. Copper is a natural remedy which could potentially reduce hospital acquired infections without the use of antibiotics and its associated risks of antibiotic resistance.Aim To develop gestational age-based reference ranges for the modified Doppler myocardial performance index (Mod MPI) and to examine the maternal characteristics that affect this measurement. Methods This was a cross-sectional study, comprised of 1021 healthy pregnancies between 20+0 to 35+6 weeks' gestation. They were all undergoing ultrasound examination in Cairo Fetal Medicine Unit (CAIFM) in Cairo University, Egypt from 1st April 2017 till 1st April 2019. Mod MPI was obtained used method described by Friedman et al. (2003). Median and SD models were fitted between Mod MPI and gestational age. The distributions of Mod MPI Z-scores were examined in relation to maternal characteristics RESULTS The normal Mod MPI in second and third trimester (20 + 1 to 35 + 6 weeks' gestation) was 0.408 ± 0.08. Mod MPI was not affected by maternal age, body mass index (BMI) or parity (p value 0.5, 0.6 and 0.2 respectively). Conclusion This study established normal reference ranges for Mod MPI according to gestational age and generated a graph with 5th,10th, 90th and 95th centiles. Maternal characteristics as age, BMI or parity do not affect value of Mod MPI.Objective To identify factors predictive of high discordance (>20 mm) between lesion sizes measured by magnetic resonance imaging (MRI) and histology for invasive lobular breast cancer. Materials and methods Data for all women with invasive lobular breast cancer (pure or associated with a component of invasive ductal carcinoma) between 1st January 2007 and 31st December 2016 were included in this study. Logistic regression analysis was performed to determine factors predictive of high discordance (underestimation/overestimation by >20 mm) between tumour sizes measured by MRI and histology for invasive lobular breast cancer. Results For overestimation, significant factors on univariate analysis were menopausal status [odds ratio (OR) 0.27, 95 % confidence interval (CI) 0.10-0.71]; p = 0.01], hormone receptor (HR) status (HR negative, OR 1.64, 95 % CI 0.27-9.89; HR positive, OR 0.64, 95 % CI 0.21-1.88; p = 0.09) and neoadjuvant chemotherapy (OR 10.33, 95 % CI 3.58-29.8; p less then 0.001). On multivariate analysis, menopausal status and neoadjuvant chemotherapy were found to be independent predictive factors of overestimation.
