Meta-Analysis
BACKGROUND
Neonates born through meconium-stained amniotic fluid (MSAF) are at risk of developing meconium aspiration syndrome (MAS). Neonates who are non-vigorous due to intrapartum asphyxia are at higher risk of developing MAS. Clearance of meconium from the airways below the vocal cords by tracheal suction before initiating other steps of resuscitation may reduce the risk of development of MAS. However, conducting tracheal suction may not only be ineffective, it may also delay effective resuscitation, thus prolonging and worsening the hypoxic-ischaemic insult. OBJECTIVES: To evaluate the efficacy of tracheal suctioning at birth in preventing meconium aspiration syndrome and other complications among non-vigorous neonates born through meconium-stained amniotic fluid.
SEARCH METHODS
We used the standard search strategy of Cochrane Neonatal to search Cochrane Central Register of Controlled Trials (CENTRAL 2020, Issue 11) in the Cochrane Library; Ovid MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Daily and Versions(R) (1946 to 25 November 2020) for randomised controlled trials (RCTs) and quasi-randomised trials. We also searched clinical trials databases and the reference lists of retrieved articles for RCTs and quasi-randomised trials (up to November 2020).
SELECTION CRITERIA
We included studies enrolling non-vigorous neonates born through MSAF, if the intervention being tested included tracheal suction at the time of birth with an intent to clear the trachea of meconium before regular breathing efforts began. Tracheal suction could be performed with an endotracheal tube or a wide-gauge suction catheter. Neonates in the control group should have been resuscitated at birth with no effort made to clear the trachea of meconium.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trial quality and extracted data, consulting with a third review author about any disagreements. We used standard Cochrane methodological procedures, including assessment of risk of bias for all studies. Our primary outcomes were: MAS; all-cause neonatal mortality; and incidence of hypoxic-ischaemic encephalopathy (HIE). Secondary outcomes included: need for mechanical ventilation; incidence of pulmonary air leaks; culture-positive sepsis; and persistent pulmonary hypertension. We used the GRADE approach to assess the certainty of evidence.
MAIN RESULTS
We included four studies (enrolling 581 neonates) in the review. All four studies were conducted in tertiary care hospitals in India. Three of the four studies included neonates born at and beyond term gestation, whereas one included neonates born at and beyond 34 weeks of gestation. Due to the nature of the intervention, it was not possible to blind the healthcare personnel conducting the intervention. Tracheal suction compared to no suction in non-vigorous neonates born through MSAF In non-vigorous infants, no differences were noted in the risks of MAS (RR 1.00, 95% CI 0.80 to 1.25; RD 0.00, 95% CI -0.07 to 0.08; 4 studies, 581 neonates) or all-cause neonatal mortality (RR 1.24, 95% CI 0.76 to 2.02; RD 0.02, 95% CI -0.03 to 0.07; 4 studies, 575 neonates) with or without tracheal suctioning. No differences were reported in the risk of any severity HIE (RR 1.05, 95% CI 0.68 to 1.63; 1 study, 175 neonates) or moderate to severe HIE (RR 0.68, 95% CI 0.43 to 1.09; 1 study, 152 neonates) among non-vigorous neonates born through MSAF. We are also uncertain as to the effect of tracheal suction on other outcomes such as incidence of mechanical ventilation (RR 0.99, 95% CI 0.68 to 1.44; RD 0.00, 95% CI -0.06 to 0.06; 4 studies, 581 neonates), pulmonary air leaks (RR 1.22, 95% CI 0.38 to 3.93; RD 0.00, 95% CI -0.02 to 0.03; 3 studies, 449 neonates), persistent pulmonary hypertension (RR 1.29, 95% CI 0.60 to 2.77; RD 0.02, 95% CI -0.03 to 0.06; 3 studies, 406 neonates) and culture-positive sepsis (RR 1.32, 95% CI 0.48 to 3.57; RD 0.01, 95% CI -0.03 to 0.05; 3 studies, 406 neonates). All reported outcomes were judged as providing very low certainty evidence.
AUTHORS' CONCLUSIONS
We are uncertain about the effect of tracheal suction on the incidence of MAS and its complications among non-vigorous neonates born through MSAF. One study awaits classification and could not be included in the review. More research from well-conducted large trials is needed to conclusively answer the review question.

BACKGROUND
Previous biomechanical studies have identified capsular closure, labral repair or reconstruction, and osteochondroplasty as important surgical interventions to improve hip stability.
PURPOSE
To investigate the outcome metrics used to quantify hip stability and assess and measure the relative contributions of the labrum, capsule, and bone to hip stability through a quantitative analysis.
STUDY DESIGN
Systematic review and meta-analysis; Level of evidence, 4.
METHODS
PubMed and Embase databases were searched using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Included studies evaluated cadaveric hip biomechanics related to capsular, labral, and bony management during hip arthroscopy. Studies were assessed for distraction force and distance, fluid measures, and contact forces used to quantify the suction seal. Exclusion criteria included open surgery, arthroplasty, reorientation osteotomy, or traumatic dislocation.
RESULTS
A total of 33 biomechanical studies comprising 322 hips that evaluated 1 or more of the following were included: distraction force or distance (24 studies), fluid measures (10 studies), and contact forces (6 studies). Compared with a capsulotomy or capsulectomy, capsular repair or reconstruction demonstrated greater resistance to distraction (standardized mean difference [SMD], 1.13; 95% CI, 0.46-1.80; = .0009). Compared with a labral tear, a labral repair or reconstruction demonstrated less resistance to distraction (SMD, -0.67; 95% CI, -1.25 to -0.09; = .02). Compared with a labral debridement, repair or reconstruction demonstrated greater resistance to distraction (SMD, 1.74; 95% CI, 1.23 to 2.26; < .00001). No quantitative analysis was feasible from studies evaluating the effect of osseous resection due to the heterogeneity in methodology and outcome metrics assessed.
CONCLUSION
Most biomechanical evidence supports capsulotomy repair or reconstruction to improve hip distractive stability at the end of hip arthroscopic surgery. While the repair of a torn labrum does not improve distractive resistance, it is superior to labral debridement in most biomechanical studies.

Meta-Analysis
The diagnosis of Hirschsprung disease (HD) depends on the histopathological analysis of rectal biopsies. This review aims to define the best rectal biopsy technique. A systematic literature review and proportional meta-analysis of the available case series studies of rectal biopsies were performed in this study. All case series with more than five rectal biopsies in children younger than 18 years of age suspected of HD that described at least one type of rectal biopsy were included. The studies that did not specify the rate of conclusive results and the rate of complications of the biopsy procedures were excluded. According to the literature review, there were four different techniques of rectal biopsy: open, suction, punch, and endoscopic. In the title and abstract screening process, we assessed 496 articles, 159 fulfilled the eligibility criteria, and 71 studies reported our outcomes of interest and were included in the meta-analysis. The pooled proportion of conclusive results was 94% in open biopsies (95% CI 0.89-0.98), 95% in punch (95% CI 0.90-0.98), and 88% in suction group (95% CI 0.85-0.92). The pooled proportion of complication rates was 2% in open biopsies (95% CI 0.00031-0.04), 0.039% in suction (95% CI 0.00023-0.0006), and 2% in punch biopsies (95% CI 0.00075-0.04). Suction, punch, and open techniques presented comparable rates of conclusive results. In the suction group, the association between different methods of histopathological analysis increased conclusive results rates; however, the punch biopsy was associated with significantly higher complication rates than the suction technique.

Review
BACKGROUND
Negative pressure wound therapy (NPWT) has been described as an effective treatment for wounds of various etiologies, however it is expensive. Various authors have investigated low-cost alternatives to commercial NPWT devices. A systematic review summarizing their findings is needed for clinicians operating in resource-limited locations and for those interested in potential cost savings.
METHODS
A systematic review was performed evaluating articles from Cochrane, PubMed and EMBASE. The studies included randomized controlled trials (RCTs) and controlled clinical trials (CCTs) that compared commercially available Vacuum-Assisted Closure (VAC) devices with non-commercial NPWT modalities in human subjects.
RESULTS
Seven hundred and ninety-six articles were retrieved, of which six met inclusion criteria. All six studies were RCTs and had in total 409 participants with wounds of various etiologies, including acute, chronic, and traumatic wounds. All studies compared VAC to a non-commercial NPWT device. Five studies were found to have low risk of bias, and one study had high risk of bias. There were three types of non-commercial NPWT devices used: wall suction applied to a sealed gauze dressing (GSUC), AquaVac, and Redon drains. The following outcomes were assessed: granulation tissue formation, effect on wound size area, skin graft take, pain/time associated with dressing changes and cost. In trials that compared GSUC vs VAC, there was no significant difference between the two groups for the following outcomes: granulation tissue formation, effect on wound size and skin graft take. GSUC dressings were significantly less painful and less time-consuming than VAC dressings. In the trial that compared AquaVac vs VAC, there was no significant difference between the two groups for the following outcomes: granulation tissue formation, effect on wound size, and the time or pain associated with dressing changes. In the trial that compared Redon drains vs VAC, there was significantly more granulation tissue formed in the VAC group. All non-commercial NPWT devices were found to be less costly than VAC.
CONCLUSION
The data from the trials evaluated in this review indicate that GSUC and AquaVac are two non-commercial NPWT devices that are non-inferior to VAC for various outcomes while also being less costly. GSUC was less painful and less time-consuming than VAC. Of the non-commercial NPWT devices evaluated in this review, GSUC had the most evidence to support its future use. Prospective, multi-institutional RCTs with a large sample size are needed to confirm the findings presented here.

Review
Operative hysteroscopy in the minimally invasive management of interstitial pregnancy and interstitially retained products of conception: A case report and systematic literature review.
OBJECTIVE
An interstitial pregnancy is a rare form of ectopic pregnancy. Diagnosis and management can be challenging. Treatment often involves invasive uterine surgery. Conservative options such as methotrexate are important alternatives nowadays. The aim of this review is to investigate the role of operative hysteroscopy in the organ and fertility preserving management of interstitial pregnancy and interstitially retained products of conception (RPOC).
METHODS
A case is presented in which interstitially RPOC were removed using hysteroscopic morcellation under laparoscopic guidance. Consequently, a systematic literature review was performed.Medline, Embase and The Cochrane Library were used as literature resources.
RESULTS
In the literature review, 14 case reports in which operative hysteroscopy was part of the minimally invasive treatment of interstitial pregnancy and interstitially RPOC of which 11 were studied. Of these 14 cases, 11 were reported as being successful. Different techniques such as laparoscopy and suction curettage were associated. Various hysteroscopic instruments were used, hysteroscopic graspers most commonly. Reported complications were uterine perforation during suction curettage and incomplete hysteroscopic resection. Analysis of the cases did not demonstrate a clear difference between different approaches concerning safety, efficacy or subsequent fertility and pregnancy outcomes.
CONCLUSION
With the growing experience in hysteroscopy and the development of novel techniques and devices, such as hysteroscopic morcellation, operative hysteroscopy has a promising role in the minimally invasive management of interstitial pregnancy and interstitially RPOC. (Laparoscopically guided) operative hysteroscopy might be a convenient approach to avoid blind curettage and related complications such as uterine perforation.

Review
OBJECTIVE
Postpartum hemorrhage is a leading cause of maternal mortality and morbidity around the globe. The novel low-suction vacuum hemorrhage device (VHD) provides an alternative treatment option for cases of postpartum hemorrhage when first-line uterotonic agents fail. This systematic review aims to review current data evaluating the overall efficacy and safety of VHDs in treating postpartum hemorrhage.
METHODS
We searched CINAHL Ultimate, Academic Search Premier, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, MEDLINE with Full Text, and PubMed and reference lists of retrieved studies for eligible studies that included outcomes of effectiveness, efficacy, or safety. Two independent reviewers used Covidence.org to screen Titles and Abstracts for 69 studies of which six were included in the analysis. Secondary outcomes measured across studies included time to bleeding control, total device deployment time, and adverse effects.
RESULTS
Six nonrandomized trials ( = 1018 participants) included studies conducted in Indonesia, the United States, Switzerland, and Canada. The VHDs were found to have 90% effectiveness in achieving bleeding control across the studies. For most patients, this was achieved in <5 min and required a total device deployment time of 3 h. Reported adverse events were not considered life-threatening, including endometritis in 11 patients and red blood cell transfusions in 38% of patients.
CONCLUSION
VHDs have the potential to be used as a rapidly effective means for mechanical intervention of postpartum hemorrhage. The efficacy and safety of VHDs must be further studied at the randomized controlled trial level to determine their clinical usage.

Methods of Quantifying Intraoperative Blood Loss in Orthopaedic Trauma Surgery: A Systematic Review.Journal of Orthopaedic Trauma Jun 2022To collect and present the recently published methods of quantifying blood loss (BL) in orthopaedic trauma.
OBJECTIVES
To collect and present the recently published methods of quantifying blood loss (BL) in orthopaedic trauma.
DATA SOURCES
A systematic review of English-language literature in PubMed, Cochrane Library, and Scopus databases was conducted according to the PRISMA guidelines on articles describing the methods of determining BL in orthopaedic trauma published since 2010.
STUDY SELECTION
English, full-text, peer-reviewed articles documenting intraoperative BL in an adult patient population undergoing orthopaedic trauma surgery were eligible for inclusion.
DATA EXTRACTION
Two authors independently extracted data from the included studies. Articles were assessed for quality and risk of bias using the Cochrane Collaboration's tool for assessing risk of bias and ROBINS-I.
DATA SYNTHESIS
The included studies proved to be heterogeneous in nature with insufficient data to make data pooling and analysis feasible.
CONCLUSIONS
Eleven methods were identified: 6 unique formulas with multiple variations, changes in hemoglobin and hematocrit levels, measured suction volume and weighed surgical gauze, transfusion quantification, cell salvage volumes, and hematoma evacuation frequency. Formulas included those of Gross, Mercuriali, Lisander, Sehat, Foss, and Stahl, with Gross being the most common (25%). All formulas used blood volume estimation, determined by equations from Nadler (94%) or Moore (6%), and measure change in preoperative and postoperative blood counts. This systematic review highlights the variability in BL estimation methods published in current orthopaedic trauma literature. Methods of quantifying BL should be taken into consideration when designing and evaluating research.

Meta-Analysis Review
BACKGROUND
Aerosols and spatter are generated in a dental clinic during aerosol-generating procedures (AGPs) that use high-speed hand pieces. Dental healthcare providers can be at increased risk of transmission of diseases such as tuberculosis, measles and severe acute respiratory syndrome (SARS) through droplets on mucosae, inhalation of aerosols or through fomites on mucosae, which harbour micro-organisms. There are ways to mitigate and contain spatter and aerosols that may, in turn, reduce any risk of disease transmission. In addition to personal protective equipment (PPE) and aerosol-reducing devices such as high-volume suction, it has been hypothesised that the use of mouth rinse by patients before dental procedures could reduce the microbial load of aerosols that are generated during dental AGPs.
OBJECTIVES
To assess the effects of preprocedural mouth rinses used in dental clinics to minimise incidence of infection in dental healthcare providers and reduce or neutralise contamination in aerosols.
SEARCH METHODS
We used standard, extensive Cochrane search methods. The latest search date was 4 February 2022.
SELECTION CRITERIA
We included randomised controlled trials and excluded laboratory-based studies. Study participants were dental patients undergoing AGPs. Studies compared any preprocedural mouth rinse used to reduce contaminated aerosols versus placebo, no mouth rinse or another mouth rinse. Our primary outcome was incidence of infection of dental healthcare providers and secondary outcomes were reduction in the level of contamination of the dental operatory environment, cost, change in mouth microbiota, adverse events, and acceptability and feasibility of the intervention.
DATA COLLECTION AND ANALYSIS
Two review authors screened search results, extracted data from included studies, assessed the risk of bias in the studies and judged the certainty of the available evidence. We used mean differences (MDs) and 95% confidence intervals (CIs) as the effect estimate for continuous outcomes, and random-effects meta-analysis to combine data MAIN RESULTS: We included 17 studies with 830 participants aged 18 to 70 years. We judged three trials at high risk of bias, two at low risk and 12 at unclear risk of bias. None of the studies measured our primary outcome of the incidence of infection in dental healthcare providers. The primary outcome in the studies was reduction in the level of bacterial contamination measured in colony-forming units (CFUs) at distances of less than 2 m (intended to capture larger droplets) and 2 m or more (to capture droplet nuclei from aerosols arising from the participant's oral cavity). It is unclear what size of CFU reduction represents a clinically significant amount. There is low- to very low-certainty evidence that chlorhexidine (CHX) may reduce bacterial contamination, as measured by CFUs, compared with no rinsing or rinsing with water. There were similar results when comparing cetylpyridinium chloride (CPC) with no rinsing and when comparing CPC, essential oils/herbal mouthwashes or boric acid with water. There is very low-certainty evidence that tempered mouth rinses may provide a greater reduction in CFUs than cold mouth rinses. There is low-certainty evidence that CHX may reduce CFUs more than essential oils/herbal mouthwashes. The evidence for other head-to-head comparisons was limited and inconsistent. The studies did not provide any information on costs, change in micro-organisms in the patient's mouth or adverse events such as temporary discolouration, altered taste, allergic reaction or hypersensitivity. The studies did not assess acceptability of the intervention to patients or feasibility of implementation for dentists. AUTHORS' CONCLUSIONS: None of the included studies measured the incidence of infection among dental healthcare providers. The studies measured only reduction in level of bacterial contamination in aerosols. None of the studies evaluated viral or fungal contamination. We have only low to very low certainty for all findings. We are unable to draw conclusions regarding whether there is a role for preprocedural mouth rinses in reducing infection risk or the possible superiority of one preprocedural rinse over another. Studies are needed that measure the effect of rinses on infectious disease risk among dental healthcare providers and on contaminated aerosols at larger distances with standardised outcome measurement.

Meta-Analysis
BACKGROUND
Compromised wound healing following stoma reversal is a frequent problem. The use of negative suction drainage for reduction of complications remains controversial.
METHODS
The patient database of our center was reviewed for patients with ileostomy reversal between 2007 and 2017. Risk factors for wound complications were analyzed using multivariate regression analysis. Systematic review and meta-analysis was performed. Ultimately, results of this study were integrated into meta-analysis to assess the effect of drainage placement on wound healing.
RESULTS
In our institutional analysis, a total of 406 patients with ileostomy reversal were included (n = 240 (59.1%) with drainage vs. n = 166 (40.8%) without drainage). In multivariate analysis, body mass index (BMI) was a risk factor for wound complications (odds ratio (95% CI) 1.06 (1.02-1.12)). Patients with drainage needed significantly fewer interventions than those without drainage (17.1% vs. 28.9%, p = 0.005). Placement of drainage significantly reduced the risk of wound complications even in the group with elevated BMI (odds ratio (95% CI) 0.462 (0.28-0.76), p = 0.003). Meta-analysis identified 6 studies with a total of 1180 patients eligible for further analysis (2 prospectively randomized trials; 4 retrospective cohort studies). Overall analysis revealed a significantly beneficial effect of wound drainage following ileostomy reversal (RR (95% CI) 0.47 (0.34, 0.66); p < 0.0001).
CONCLUSION
In our institutional analysis as well as meta-analysis, the use of subcutaneous suction drains was beneficial for prevention of wound healing complications following ostomy reversal. Drainage placement is especially valuable in high-risk situations such as in obese patients.
