Abstract
PURPOSE The relationship between multifetal cesarean delivery and surgical-site infection (SSI) is unclear. If SSI is more common in multifetal cesareans, adjustment of practices such as antibiotic dosing could be warranted. The purpose of this study was to determine whether patients undergoing multifetal cesarean delivery are more likely to experience SSI than those undergoing singleton cesarean delivery. METHODS This was a retrospective cohort study including all cesarean deliveries at a tertiary hospital from 10/1/2009 to 12/28/2018. The primary outcome was rate of SSI in women after multifetal cesarean delivery as compared to those who underwent singleton cesarean delivery. Univariable analysis and multivariable logistic regression were used to assess independent clinical factors associated with SSI in multifetal cesarean deliveries. RESULTS 34,340 women underwent cesarean delivery during this period. 33,211 were singletons (96.7%), and 1,129 were multifetal (3.3%). There was no difference in the rate of SSI in multifetal gestations (15/1,129, 1.3%) as compared to singletons (493/33,211, 1.5%) (p = 0.670, OR 0.89 [95% CI 0.53, 1.50], aOR 1.06 [95% CI 0.61, 1.84]). Limiting analysis to multifetal deliveries, prolonged rupture of membranes (p < 0.004, OR 5.43 [95% CI 1.49, 19.88]), labor augmentation (p < 0.001, OR 15.84 [1.74, 144.53]), and chorioamnionitis (p < 0.001, OR 15.43 [95% CI 3.11, 76.62]) were more common in women with SSI. DISCUSSION SSI is not increased in multifetal cesarean delivery as compared to singleton cesarean delivery. In multifetal cesareans, chorioamnionitis, prolonged rupture of membranes, and labor augmentation were associated with increased odds of SSI.

Am J Obstet Gynecol MFM 2024; 6:101354. [PMID: 38494155 DOI: 10.1016/j.ajogmf.2024.101354] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Revised: 02/27/2024] [Accepted: 03/07/2024] [Indexed: 03/19/2024]
Abstract
OBJECTIVE This study aimed to identify evidence-based peripartum interventions for people with a body mass index ≥40 kg/m2. DATA SOURCES PubMed, MEDLINE, EMBASE, Cochrane, CINAHL, and ClinicalTrials.gov were searched from inception to 2022 without date, publication type, or language restrictions. STUDY ELIGIBILITY CRITERIA Cohort and randomized controlled trials that implemented an intervention and evaluated peripartum outcomes of people with a body mass index ≥40 kg/m2 were included. The primary outcome depended on the intervention but was commonly related to wound morbidity after cesarean delivery (ie, infection, separation, hematoma). METHODS Meta-analysis was completed for interventions with at least 2 studies. Pooled risk ratios with 95% confidence intervals and heterogeneity (I2 statistics) were reported. RESULTS Of 20,301 studies screened, 30 studies (17 cohort and 13 randomized controlled trials) encompassing 10 types of interventions were included. The interventions included delivery planning (induction of labor, planned cesarean delivery), antibiotics during labor induction or for surgical prophylaxis, 6 types of cesarean delivery techniques, and anticoagulation dosing after a cesarean delivery. Planned cesarean delivery compared with planned vaginal delivery did not improve outcomes according to 3 cohort studies. One cohort study compared 3 g with 2 g of cephazolin prophylaxis for cesarean delivery and found no differences in surgical site infections. According to 3 cohort studies and 2 randomized controlled trials, there was no improvement in outcomes with a non-low transverse skin incision. Ten studies (4 cohort and 6 randomized controlled trials) met the inclusion criteria for the meta-analysis. Two randomized controlled trials compared subcuticular closure with suture vs staples after cesarean delivery and found no differences in wound morbidity within 6 weeks of cesarean delivery (n=422; risk ratio, 1.09; 95% confidence interval, 0.75-1.59; I2=9%). Prophylactic negative-pressure wound therapy was compared with standard dressing in 4 cohort and 4 randomized controlled trials, which found no differences in wound morbidity (cohort n=2200; risk ratio, 1.19; 95% confidence interval, 0.88-1.63; I2=66.1%) or surgical site infections (randomized controlled trial n=1262; risk ratio, 0.90; 95% confidence interval, 0.63-1.29; I2=0). CONCLUSION Few studies address interventions in people with a body mass index ≥40 kg/m2, and most studies did not demonstrate a benefit. Either staples or suture are recommended for subcuticular closure, but available data do not support prophylactic negative-pressure wound therapy after cesarean delivery for people with a body mass index ≥40 kg/m2.

Abstract
OBJECTIVE The aim of this study was to examine whether vertical versus transverse skin incision is associated with increased wound complications in superobese women undergoing cesarean. STUDY DESIGN This is a secondary analysis of a retrospective cohort study that included women with a body mass index (BMI) ≥ 50 kg/m2 and a cesarean birth with documented skin incision type from 1/1/2008 to 12/31/2015 at a single academic medical center. The primary outcome was a composite of wound complications: infection requiring antibiotics including superficial cellulitis, deep and organ space infections requiring packing, vacuum placement or exploration and debridement in the operating room. Secondary outcomes included estimated blood loss (EBL), time from skin incision to delivery, need for classical or T-hysterotomy, prolonged hospital admission (>4 days), and a composite of adverse neonatal outcomes. The primary exposure was skin incision type, transverse or vertical. Modified Poisson regression variance was used to adjust for differences in baseline characteristics. RESULTS During the study period, 298 women underwent a cesarean with a known skin incision type. Vertical skin incision occurred in 25.8%. Women with a vertical skin incision were younger, had a higher BMI at delivery, had less weight gain in pregnancy, and were less likely to have labored prior to cesarean. Wound complications were not significantly more common in women with a vertical skin incision after adjusting for covariates (vertical 48.1 vs. transverse 29.4%, adjusted relative risk (aRR): 1.31, 95% confidence interval [CI]: 0.92-1.86). Compared with a transverse skin incision, vertical skin incision was associated with an increased risk for classical hysterotomy (67 vs. 17%, aRR: 2.96, 95% CI: 2.12-4.14), higher EBL, prolonged hospital stay, and composite neonatal morbidity. There were no statistically significant differences in the time from skin incision to delivery. CONCLUSION In superobese women, vertical skin incision was not associated with increased wound complications, but was associated with increased risk for classical hysterotomy. KEY POINTS · Vertical skin incision was not associated with a higher risk for composite wound morbidity after adjusting for covariates.. · Vertical skin incision was significantly associated with classical hysterotomy without associated decrease in incision to delivery time or neonatal morbidity.. · When selecting a skin incision approach in superobese women, clinicians should consider whether potential benefits outweigh known risks..

Abstract
Appropriate surgical antimicrobial prophylaxis (SAP) is an important measure in preventing surgical site infections (SSIs). Although antimicrobial pharmacokinetics-pharmacodynamics (PKPD) is integral to optimizing antibiotic dosing for the treatment of infections, there is less research on preventing infections postsurgery. Whereas clinical studies of SAP dose, preincision timing, and redosing are informative, it is difficult to isolate their effect on SSI outcomes. Antimicrobial PKPD aims to explain the complex relationship between antibiotic exposure during surgery and the subsequent development of SSI. It accounts for the many factors that influence the PKs and antibiotic concentrations in patients and considers the susceptibilities of bacteria most likely to contaminate the surgical site. This narrative review examines the relevance and role of PKPD in providing effective SAP. The dose-response relationship i.e., association between lower dose and SSI in cefazolin prophylaxis is discussed. A comprehensive review of the evidence for an antibiotic concentration-response (SSI) relationship in SAP is also presented. Finally, PKPD considerations for improving SAP are explored with a focus on cefazolin prophylaxis in adults and outstanding questions regarding its dose, preincision timing, and redosing during surgery.

Abstract
Obesity is a major determinant of health outcomes and is on the increase in women worldwide. It predisposes to surgical site infection (SSI). Risk factors for the SSI include extremes of age, smoking, comorbidities such as hypertension and diabetes, inappropriate vertical abdominal and or uterine wall incisions, increased operating time, subcutaneous layer of 3 cm or more, and unnecessary use of subcutaneous drain. Most bacteria that cause SSIs are human commensals. Common organisms responsible for SSI include Staphylococcus aureus and coliforms such as Proteus mirabilis, and Escherichia coli. A surgeon's gloves post caesarean section in the obese has a preponderance of Firmicutes and Bacteroidetes, which increases SSI risk. The interaction of skin commensals and vaginal microbiome at the surgical incision site increases the risk of SSI in the obese compared to non-obese. Minimizing the risk of SSI involves modification of risk factors, timely treatment of SSI to prevent sepsis and compliance with the recommended care bundles.

Abstract
OBJECTIVE Despite the growing prevalence of obesity among reproductive aged persons in the USA, evidence-based guidelines for peripartum care are lacking. The objective of this scoping review is to identify obesity-related recommendations for peripartum care, evaluate grades of evidence for each recommendation, and identify practical tools (eg, checklists, toolkits, care pathways and bundles) to support their implementation in clinical practice. DATA SOURCES We searched MEDLINE, EMBASE, CINAHL, the Cochrane Central Register of Controlled Trials and ClinicalTrials.gov from inception to December 2020 for eligible studies addressing peripartum care in persons with obesity. STUDY ELIGIBILITY CRITERIA Inclusion criteria were published evidence-rated recommendations and practical tools for peripartum care of persons with obesity. STUDY APPRAISAL AND SYNTHESIS METHODS Pairs of independent reviewers extracted data (source, publication year, content and number of recommendations, level and grade of evidence, description of tool) and identified similarities and differences among the articles. RESULTS Of 18 315 screened articles, 18 were included including 7 articles with evidence-rated recommendations and 11 practical tools (3 checklists, 3 guidelines, 1 care bundle, 1 flowchart, 1 care pathway, 1 care map and 1 protocol). Thirteen of 39 evidence-rated recommendations were based on expert opinion. Recommendations related to surgical antibiotic prophylaxis and subcutaneous tissue closure at caesarean delivery received the highest grade of evidence. Some of the practical tools included a checklist from the USA regarding anticoagulation after caesarean delivery (evidence-supported recommendation), a bundle for surgical site infections after caesarean delivery in Australia (evidence did not support recommendation) and a checklist with content for several aspects of peripartum care from Canada (evidence supported seven of nine definitive recommendations). CONCLUSION The recommendations for peripartum care for persons with obesity are based on limited evidence and few practical tools for implementation exist. Future work should focus on developing practical tools based on high-quality studies.

Abstract
Currently, there is no consensus on whether a standard 2-g prophylactic cefazolin dose provides sufficient antimicrobial coverage in obese surgical patients. This systematic review analysed both outcome and pharmacokinetic studies, aiming to determine the appropriate cefazolin dose. A systematic search was conducted using 4 databases. In total, 3 outcome and 15 pharmacokinetic studies met the inclusion criteria. All 3 outcome studies concluded that there is no need for increased dose. Also, 9 pharmacokinetic studies reached this conclusion; however, 6 pharmacokinetic studies recommended that 2-g dose is insufficient to achieve adequate plasma or tissue concentrations. The stronger body of evidence supports that 2-g dose of cefazolin is sufficient for surgery lasting up to 4 h; however, large-scale outcome studies are needed to confirm this evidence.

Abstract
Pregnant women with obesity are at increased risk of a multitude of complications of pregnancy and adverse perinatal outcomes. The risk of some of these complications, such as neural tube defects or preeclampsia, may be mitigated by some medications. Other complications, such as diabetes, venous thromboembolism, and infections, require treatment with medications. Given the changes in pharmacokinetics and pharmacodynamics during pregnancy, which is further enhanced by obesity, the optimal medication and its dose is often researched. This chapter further explores the different complications and common medications that women with obesity are likely to require.

Abstract
(1) Background: Caesarean sections in obese patients are associated with an increased risk of surgical wound complications, including hematomas, seromas, abscesses, dehiscence, and surgical site infections. The aim of the present study is to perform a meta-analysis and systematic review of the current literature focusing on the strategies available to decrease wound complications in this population. (2) Methods: We reviewed the data available from the PubMed and the Science Direct databases concerning wound complications after caesarean sections in obese women. The following key words were used: “caesarean section”, “cesarean section”, “wound complication”, “wound morbidity”, and “wound infection”. A total of 540 papers were retrieved, 40 of which were selected for the final systematic review and whereas 21 articles provided data for meta-analysis. (3) Results: The conducted meta-analyses revealed that the use of prophylactic drainage does not increase the risk of wound complications in obese women after a caesarean sections (pooled OR = 1.32; 95% CI 0.64–2.70, p = 0.45) and that vertical skin incisions increase wound complications (pooled OR = 2.48; 95% CI 1.85–3.32, p < 0.01) in obese women, including extremely obese women. (4) Conclusions: Subcutaneous drainage does not reduce the risk of a wound complications, wound infections, and fever in obese women after caesarean sections. Negative prophylactic pressure wound therapy (NPWT) may reduce the risk of surgical site infections. The evidence of using a prophylactic dose of an antibiotic before the caesarean section is still lacking.

Abstract
Background: In 2006, the Surgical Infection Society (SIS) utilized a modified Delphi approach to define 15 specific priority research questions that remained unanswered in the field of surgical infections. The aim of the current study was to evaluate the scientific progress achieved during the ensuing period in answering each of the 15 research questions and to determine if additional research in these fields is warranted. Methods: For each of the questions, a literature search using the National Center for Biotechnology Information (NCBI) was performed by the Scientific Studies Committee of the SIS to identify studies that attempted to address each of the defined questions. This literature was analyzed and summarized. The data on each question were evaluated by a surgical infections expert to determine if the question was answered definitively or remains unanswered. Results: All 15 priority research questions were studied in the last 14 years; six questions (40%) were definitively answered and 9 questions (60%) remain unanswered in whole or in part, mainly because of the low quality of the studies available on this topic. Several of the 9 unanswered questions were deemed to remain research priorities in 2020 and warrant further investigation. These included, for example, the role of empiric antimicrobial agents in nosocomial infections, the use of inotropes/vasopressors versus volume loading to raise the mean arterial pressure, and the role of increased antimicrobial dosing and frequency in the obese patient. Conclusions: Several surgical infection-related research questions prioritized in 2006 remain unanswered. Further high-quality research is required to provide a definitive answer to many of these priority knowledge gaps. An updated research agenda by the SIS is warranted at this time to define research priorities for the future.

Abstract
OBJECTIVE To determine the risk of wound complications by skin incision type in obese women undergoing cesarean delivery.Data sources: Electronic databases (MEDLINE, Scopus, and Ovid) were searched from their inception through August 2018.Methods of study selection: We included all randomized controlled trials and cohort studies reporting the placement of skin incision during cesarean section in obese women, defined as those with BMI ≥30 kg/m2. Studies were included if they compared one placement of skin incision with a different one as comparison group. The primary outcome was incidence of wound complications, while secondary outcomes included wound infection, hematoma, seroma, postpartum hemorrhage, and endometritis. Demographics and outcomes for each individual study identified were reported as part of the review. Meta-analysis was performed using the random effects model of DerSimonian and Laird, to produce summary treatment effects in terms of mean difference (MD) or relative risk (RR) with 95% confidence interval (CI). Sub-group analyses (vertical versus Pfannenstiel) were also reported.Tabulation, integration and results: Seventeen studies (including 3 RCTs; 8960 participants among the 15 non-overlapping studies) were included in the systematic review. Vertical incisions were associated with a relative risk of 2.07 (95% CI1.61-2.67) for wound complications compared to transverse incisions, however significant possible confounders were present. Studies were mildly-moderately heterogeneous (I2 44.81%, 95% CI 0.00-71.85%) with varying definitions of obesity and wound complications. High transverse incisions (3 studies, 218 participants) trend toward a lower risk of wound complications compared to low transverse incisions (RR 0.338, 95% CI 0.114-1.004). CONCLUSIONS Vertical incisions may be associated with an increased risk for wound complications compared to transverse incisions for cesarean delivery in obese women. Randomized controlled trials are needed to evaluate optimal cesarean skin incisions for these women.

Abstract
Cesarean delivery (CD) wound complications disrupt the time a mother spends with her newborn. Surgical site infections (SSI) may result in unplanned office visits, emergency room visits, and hospital readmissions. Despite increasing attention to preoperative preparation, the CD SSI rate remains high. Local practices must be evaluated, and new methods to reduce CD SSI must be used.

Abstract
Objetivo . Actualmente no existe evidencia clara que guíe la dosificación de cefazolina en pacientes obesos en profilaxis quirúrgica. El objetivo fue evaluar la efectividad de este antibiótico con una dosis estándar de 2 g en la prevención de infección de herida quirúrgica (IHQ) en pacientes obesos en comparación con no obesos. Material y métodos . Revisión retrospectiva de varones ≥100 kg con cefazolina profiláctica entre 1 enero y 30 junio de 2019 en un hospital universitario en el servicio de traumatología. Los pacientes fueron estratificados en 2 grupos: obesos (≥ 100 kg e índice masa corporal (IMC)>30 kg/m2) y no obesos. Fueron excluidos aquellos que carecían de seguimiento en los 90 días posteriores a la intervención quirúrgica (IQ), aquellos con infección activa en el momento de la IQ o tratados con inmunosupresores. Se recogieron datos demográficos, altura, peso real, tabaquismo, diabetes, uso concomitante de inmunosupresores, datos de la IQ y presencia de infección hasta el día 90. Resultados . 57 pacientes fueron sometidos a IQ traumatológica con cefazolina profiláctica, 26 no obesos y 23 obesos. Ambos grupos presentaron diferencias estadísticamente significativas en cuanto a peso, IMC y uso de cefazolina post-IQ. No se observaron diferencias significativas en el resto de variables. Dos (8,7%) obesos y dos (7,7%) pacientes no obesos desarrollaron IHQ, siendo la diferencia entre los grupos estadísticamente no significativa, tras 63 días post-IQ de media. Conclusión . Este estudio demuestra que no existe diferencia significativa en IHQ con la dosis profiláctica de 2 g de cefazolina entre obesos y no obesos.

Abstract
BACKGROUND The clinical pharmacists have a sensible role in the implementation of guidelines by ensuring proper patient selection and medication use. This study aimed to implement a hospital guideline for the rational use of prophylactic antibiotics in elective cesarean sections (ECS) by establishing compliance with international guidelines regarding prophylactic antibiotic use in ECS at Elqutainah Teaching Hospital in White Nile State, Sudan, and define the area of medication cost-saving. METHODS A quasi-experimental design without control group was used from April to June 2018. 195 participants were included, 94 participants before and 101 participants after the intervention and data were collected using a designed checklist by the researchers. The intervention is based on withdrawal metronidazole dosage forms from prophylactic antibiotics for ECS according to international guidelines in antibiotics prophylaxis toward ECS. Finally, the data were compared between pre- and post-intervention. FINDINGS Before intervention; all participants had received intravenous cefuroxime and metronidazole infusions prior ECS and oral cefuroxime or amoxicillin-clavulanic acid, and metronidazole for 7 days upon discharge. While after the intervention, all participants didn't receive any metronidazole dosage forms before and after ECS also didn't receive amoxicillin-clavulanic acid. However, the dosage regimen of cefuroxime didn't change. This intervention was meaningful in minimizing overuse of antibiotics prophylaxis in the ECS, and reducing staff workload along with medication cost. CONCLUSIONS Clinical pharmacist intervention was concisely changing the physicians' practice toward using updated guidelines of the rational use of prophylactic antibiotics for ECS.

Abstract
Health care-associated infections (HAIs) are a global problem associated with significant morbidity and mortality. Controlling the spread of antimicrobial-resistant bacteria is a major public health challenge, and antimicrobial resistance has become one of the most important global problems in current times. The antimicrobial effect of copper has been known for centuries, and ongoing research is being conducted on the use of copper-coated hard and soft surfaces for reduction of microbial contamination and, subsequently, reduction of HAIs. This review provides an overview of the historical and current evidence of the antimicrobial and wound-healing properties of copper and explores its possible utility in obstetrics and gynecology.

Abstract
Importance Surgical site infection (SSI) is a common complication of cesarean delivery. Seen in up to 12% of cesarean deliveries, it is a major cause of prolonged hospital stay and a burden to the healthcare system. Interventions and techniques must be identified to decrease the risk of cesarean delivery SSIs. Objective We review the categories of SSI, current studies that have focused on various interventions to decrease SSI, and preoperative, intraoperative, and postoperative recommendations for cesarean delivery SSI prevention. Evidence Acquisition A thorough search of PubMed for all current literature was performed. Various surgical interventions and techniques were reviewed. We included studies that looked at preoperative, intraoperative, and postoperative interventions for SSI prevention. Results We have summarized several surgical interventions and techniques as well as current consensus statements to aid the practitioner in preventing SSIs after cesarean delivery. Conclusions and Relevance Upon analysis of current data and consensus statements pertaining to cesarean deliveries, there are certain preoperative, intraoperative, and postoperative interventions and techniques that can be recommended to decrease the risk of cesarean delivery SSI.

Does the human placenta delivered at term have a microbiota? Results of cultivation, quantitative real-time PCR, 16S rRNA gene sequencing, and metagenomics. Am J Obstet Gynecol 2019; 220:267.e1-267.e39.

Abstract
BACKGROUND The human placenta has been traditionally viewed as sterile, and microbial invasion of this organ has been associated with adverse pregnancy outcomes. Yet, recent studies that utilized sequencing techniques reported that the human placenta at term contains a unique microbiota. These conclusions are largely based on the results derived from the sequencing of placental samples. However, such an approach carries the risk of capturing background-contaminating DNA (from DNA extraction kits, polymerase chain reaction reagents, and laboratory environments) when low microbial biomass samples are studied. OBJECTIVE To determine whether the human placenta delivered at term in patients without labor who undergo cesarean delivery harbors a resident microbiota ("the assemblage of microorganisms present in a defined niche or environment"). STUDY DESIGN This cross-sectional study included placentas from 29 women who had a cesarean delivery without labor at term. The study also included technical controls to account for potential background-contaminating DNA, inclusive in DNA extraction kits, polymerase chain reaction reagents, and laboratory environments. Bacterial profiles of placental tissues and background technical controls were characterized and compared with the use of bacterial culture, quantitative real-time polymerase chain reaction, 16S ribosomal RNA gene sequencing, and metagenomic surveys. RESULTS (1) Twenty-eight of 29 placental tissues had a negative culture for microorganisms. The microorganisms retrieved by culture from the remaining sample were likely contaminants because corresponding 16S ribosomal RNA genes were not detected in the same sample. (2) Quantitative real-time polymerase chain reaction did not indicate greater abundances of bacterial 16S ribosomal RNA genes in placental tissues than in technical controls. Therefore, there was no evidence of the presence of microorganisms above background contamination from reagents in the placentas. (3) 16S ribosomal RNA gene sequencing did not reveal consistent differences in the composition or structure of bacterial profiles between placental samples and background technical controls. (4) Most of the bacterial sequences obtained from metagenomic surveys of placental tissues were from cyanobacteria, aquatic bacteria, or plant pathogens, which are microbes unlikely to populate the human placenta. Coprobacillus, which constituted 30.5% of the bacterial sequences obtained through metagenomic sequencing of placental samples, was not identified in any of the 16S ribosomal RNA gene surveys of these samples. These observations cast doubt as to whether this organism is really present in the placenta of patients at term not in labor. CONCLUSION With the use of multiple modes of microbiologic inquiry, a resident microbiota could not be identified in human placentas delivered at term from women without labor. A consistently significant difference in the abundance and/or presence of a microbiota between placental tissue and background technical controls could not be found. All cultures of placental tissue, except 1, did not yield bacteria. Incorporating technical controls for potential sources of background-contaminating DNA for studies of low microbial biomass samples, such as the placenta, is necessary to derive reliable conclusions.

Abstract
The Enhanced Recovery After Surgery Society guideline for intraoperative care in cesarean delivery will provide best practice, evidenced-based, recommendations for intraoperative care, with primarily a maternal focus. The "focused" pathway process for scheduled and unscheduled cesarean delivery for this Enhanced Recovery After Surgery cesarean delivery guideline will consider procedure from the decision to operate (starting with the 30-60 minutes before skin incision) through the surgery. The literature search (1966-2017) used Embase and PubMed to search medical subject headings including "cesarean section," "cesarean section," "cesarean section delivery," and all pre- and intraoperative Enhanced Recovery After Surgery items. Study selection allowed titles and abstracts to be screened by individual reviewers to identify potentially relevant articles. Metaanalyses, systematic reviews, randomized controlled studies, nonrandomized controlled studies, reviews, and case series were considered for each individual topic. Quality assessment and data analyses evaluated the quality of evidence and recommendations were evaluated according to the Grading of Recommendations, Assessment, Development and Evaluation system as used and described in previous Enhanced Recovery After Surgery Society guidelines. The Enhanced Recovery After Surgery cesarean delivery guideline/pathway has created a maternal focused pathway (for scheduled and unscheduled surgery starting from 30-60 minutes before skin incision to maternal discharge) with Enhanced Recovery After Surgery-directed preoperative elements, intraoperative elements, and postoperative elements. Specifics of the intraoperative care included the use of prophylactic antibiotics before the cesarean delivery, appropriate patient warming intraoperatively, blunt expansion of the transverse uterine hysterotomy, skin closure with subcuticular sutures, and delayed cord clamping. A number of specific elements of intraoperative care of women who undergo cesarean delivery are recommended based on the evidence. The Enhanced Recovery After Surgery Society guideline for intraoperative care in cesarean delivery will provide best practice, evidenced-based, recommendations for intraoperative care with primarily a maternal focus. When the cesarean delivery pathway (elements/processes) is studied, implemented, audited, evaluated, and optimized by maternity care teams, this will create an opportunity for the focused and optimized areas of care and recommendations to be further enhanced.

Abstract
Background Continual evolution of resistance among bacteria against methods of surgical prophylaxis may make currently used beta-lactam regimens inadequate. Objective To re-evaluate beta-lactam regimens in surgical prophylaxis. Setting A pharmacodynamic Monte Carlo simulation (MCS) model based on a number of patients in China. Methods Pharmacodynamic profiling using Monte Carlo simulation up to 4 hours postinfusion was conducted for standard-dose, short-term (0.5 h) and prolonged (2 to 4 h) infusions of ampicillin, cefazolin, cefotaxime, cefoxitin, cefuroxime, ertapenem, and piperacillin/tazobactam in adult patients with normal renal function. Microbiological data were incorporated. Cumulative fraction of response (CFR) was determined for each regimen against populations of S. aureus, coagulase-negative staphylococci and E. coli. The optimal CFR was defined as ≥ 90% response. Main Outcome Measure Cumulative fractions of response of pharmacodynamic target attainment. Results During the first 2 hours postinfusion, piperacillin/tazobactam 3.375 g exhibited consistently optimal cumulative fractions against S. aureus, CoNS and E. coli. Ampicillin 2 g (2 h) also displayed optimal CFRs for S. aureus and E. coli but not for coagulase-negative staphylococci. Cefoxitin 2 g didnot achieve any optimal CFRs, even via 2-h prolonged infusion (maximum 72.8% CFR for S. aureus and 64.5% CFR for E. coli). Cefazolin 2 g (4 h) and cefuroxime 1.5 g (4 h) provided desired CFRs across 4 h postinfusion for S. aureus but provided poor CFRs for coagulase-negative staphylococci and E. coli. Only ertapenem 1 g for E. coli and S. aureus and cefotaxime 1 g for E. coli consistently yielded ≥ 90% CFRs for 4 hour postinfusion. Conclusions Certain dosing regimens may warrant adjustment for improved prevention efficiency and enhanced empirical antibiotic regimens for surgical prophylaxis.

Abstract
BACKGROUND Clinical practice guidelines recommend a 2-g dose of cefotetan and cefoxitin for surgical prophylaxis. Pharmacokinetic data suggest benefit from higher cefotetan and cefoxitin dosing in obese patients. However, clinical studies examining higher dosing strategies in this at-risk population are lacking. The purpose of this study was to determine whether 3 g of cefotetan or cefoxitin administered pre-operatively for patients who weigh 120 kg or more is associated with a lower proportion of surgical site infection (SSI) compared with 2 g. PATIENTS AND METHODS Medical records of patients weighing 120 kg or more who had received cefotetan or cefoxitin (2 or 3 g) as surgical prophylaxis for intra-abdominal procedures between July 2012 and August 2015 were reviewed for the development of an SSI (primary outcome), study drug-related adverse events, and re-admissions attributed to SSIs (secondary outcomes). Relative risk calculations were performed for analysis of the primary and secondary outcomes. RESULTS One-hundred seventy-five procedures in 169 patients were included in the study. Cefotetan was used in 81% (141/175) of procedures. Three grams of cefotetan or cefoxitin was used in 20% (35/175) of procedures. The median body mass index (BMI) in both dosing groups was 42 kg/m2 and patients who received 3 g more often weighed more than 130 kg (relative risk [RR] 1.36, 1.01-1.76; p = 0.04). Surgical site infections occurred in 20.7% within the 2-g group and 22.9% in the 3-g group (RR 1.10, 0.55-2.20; p = 0.78). There was no difference in the number of study drug-related adverse effects in the 3-g compared with the 2-g group. Thirty-day re-admissions because of SSI also did not differ between the 2-g and 3-g groups (7.9% vs. 17.1%, respectively; p = 0.11). CONCLUSION This small retrospective study did not find a difference in SSI rates between 3-g and 2-g surgical prophylaxis dosing for patients 120 kg or more with a median BMI >40 kg/m2.

Abstract
OBJECTIVE This study sought to determine baseline Caesarean delivery (CD) surgical site infection (SSI) rates in various patient subgroups and to identify potentially modifiable and non-modifiable risk factors for SSI. METHODS This is a secondary analysis of a multicentre CD registry. Women who underwent CD were divided into SSI versus no SSI. SSI was defined as an infection that occurred in the part of the body where the surgery took place, within 30 days of surgery. Clinical characteristics and potential risk factors were compared between groups. RESULTS Of 57 182 women, 3696 (6.5%) had SSI. SSI rates were higher in primary versus repeat CD (9.7% vs. 4.2%; P <0.001), and in CD after labour vs. no labour (9.5% vs. 3.8%; P <0.001). After adjustment for confounding factors, low transverse CD (adjusted OR [aOR] 0.7 [0.6-0.9]), CD performed between 7 pm and 7 am (aOR 0.9 [0.83-0.98]), primary CD (aOR 0.5 [0.5-0.6]), and intrapartum antibiotics (aOR 0.3 [0.1-0.4]) were associated with a decreased in the rate of SSI. Black race (aOR 1.9 [1.7-2.1]), tobacco use (aOR 1.4 [1.2-1.6]), increasing American Society of Anesthesiologists category (aOR 1.3 [1.1-1.6]), vertical skin incision (aOR 1.2 [1.1-1.3], emergency CD (aOR 1.3 [1.1-1.5]), and postpartum transfusion (aOR 2.7 [2.1-3.6]) were associated with an increase in the rate of SSI. CONCLUSION This study estimates the CD SSI rates in different subgroups and serves as a baseline for future trials designed to develop preventive guidelines and protocols.

Abstract
Obesity is an important risk factor of cesarean section and is associated with an increased risk of wound complications such as infections. This review focuses on the available strategies to limit complications in this population. Choice of antiseptic solution, appropriate dose and type of antibiotic prophylaxy, suture closure of subcutaneous fat, suture skin closure and closed incision negative pressure wound therapy may reduce the risk of wound infections associated with cesarean section in obese patients. Vaginal desinfection, plastic adhesive draps, high-concentration supplemental perioperative oxygen, use of a barrier retractor, wound drainage and type of skin incision are discussed in this review. Clinical trials of good quality are needed to improve our clinical practice.

Abstract
OBJECTIVE To determine the association between maternal obesity and delivery due to chorioamnionitis prior to labor onset, among expectantly managed women with preterm premature rupture of membranes (pPROM). METHODS This was a secondary analysis of a multicenter randomized trial of magnesium sulfate versus placebo to prevent cerebral palsy or death among offspring of women with anticipated delivery at 24-31-week gestation. After univariable analysis, Cox proportional hazard evaluated the association between maternal obesity and chorioamnionitis, while Laplace regression investigated how obesity affects the gestational age at delivery of the first 20% of women developing the outcome of interest. RESULTS A total of 164 of the 1942 women with pPROM developed chorioamnionitis prior to labor onset. Obese women had a 60% increased hazard of developing such complication (adjusted HR 1.6, 95%CI 1.1-2.1, p = .008), prompting delivery 1.5 weeks earlier, as the 20th survival percentile was 27.2-week gestation (95%CI 26-28.6) among obese as opposed to 28.8 weeks (95%CI 27.4-30.1) (p = .002) among nonobese women. CONCLUSIONS Maternal obesity is a risk factor for chorioamnionitis prior to labor onset. Future studies will determine if obesity is important enough to change the management of latency after pPROM according to maternal BMI.

Abstract
IMPORTANCE The rate of obesity among US women has been increasing, and obesity is associated with increased risk of surgical site infection (SSI) following cesarean delivery. The optimal perioperative antibiotic prophylactic regimen in this high-risk population undergoing cesarean delivery is unknown. OBJECTIVE To determine rates of SSI among obese women who receive prophylactic oral cephalexin and metronidazole vs placebo for 48 hours following cesarean delivery. DESIGN, SETTING, AND PARTICIPANTS Randomized, double-blind clinical trial comparing oral cephalexin and metronidazole vs placebo for 48 hours following cesarean delivery for the prevention of SSI in obese women (prepregnancy BMI ≥30) who had received standard intravenous preoperative cephalosporin prophylaxis. Randomization was stratified by intact vs rupture of membranes prior to delivery. The study was conducted at the University of Cincinnati Medical Center, Cincinnati, Ohio, an academic and urban setting, between October 2010 and December 2015, with final follow-up through February 2016. INTERVENTIONS Participants were randomly assigned to receive oral cephalexin, 500 mg, and metronidazole, 500 mg (n = 202 participants), vs identical-appearing placebo (n = 201 participants) every 8 hours for a total of 48 hours following cesarean delivery. MAIN OUTCOMES AND MEASURES The primary outcome was SSI, defined as any superficial incisional, deep incisional, or organ/space infections within 30 days after cesarean delivery. RESULTS Among 403 randomized participants who were included (mean age, 28 [SD, 6] years; mean BMI, 39.7 [SD, 7.8]), 382 (94.6%) completed the trial. The overall rate of SSI was 10.9% (95% CI, 7.9%-14.0%). Surgical site infection was diagnosed in 13 women (6.4%) in the cephalexin-metronidazole group vs 31 women (15.4%) in the placebo group (difference, 9.0% [95% CI, 2.9%-15.0%]; relative risk, 0.41 [95% CI, 0.22-0.77]; P = .01). There were no serious adverse events, including allergic reaction, reported in either the antibiotic group or the placebo group. CONCLUSIONS AND RELEVANCE Among obese women undergoing cesarean delivery who received the standard preoperative cephalosporin prophylaxis, a postoperative 48-hour course of oral cephalexin and metronidazole, compared with placebo, reduced the rate of SSI within 30 days after delivery. For prevention of SSI among obese women after cesarean delivery, prophylactic oral cephalexin and metronidazole may be warranted. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT01194115.

Abstract
PURPOSE The purpose of this study is to build and validate a statistical model to predict infection after caesarean delivery (CD). METHODS Patient and surgical variables within 30 d of CD were collected on 2419 women. Postpartum infection included surgical site infection, urinary tract infection, endomyometritis and pneumonia. The data were split into model development and internal validation (1 January-31 August; N = 1641) and temporal validation subsets (1 September-31 December; N = 778). Logistic regression models were fit to the data with concordance index and calibration curves used to assess accuracy. Internal validation was performed with bootstrapping correcting for bias. RESULTS Postoperative infection occurred in 8% (95% CI 7.3-9.9), with 5% meeting CDC criteria for surgical site infections (SSI) (95% CI 4.1-5.8). Eight variables were predictive for infection: increasing BMI, higher number of prior Caesarean deliveries, emergent Caesarean delivery, Caesarean for failure to progress, skin closure using stainless steel staples, chorioamnionitis, maternal asthma and lower gestational age. The model discriminated between women with and without infection on internal validation (concordance index = 0.71 95% CI 0.67-0.76) and temporal validation (concordance index = 0.70, 95% CI 0.62, 0.78). CONCLUSIONS Our model accurately predicts risk of infection after CD. Identification of patients at risk for postoperative infection allows for individualized patient care and counseling.

Abstract
Cesarean delivery (CD) is one of the most common procedures performed in the United States, accounting for 32% of all deliveries. Postpartum surgical site infection (SSI), wound infection and endometritis is a major cause of prolonged hospital stay and poses a burden to the health care system. SSIs complicate a significant number of patients who undergo CD - 2-7% will experience sound infections and 2-16% will develop endometritis. Many risk factors for SSI have been described. These include maternal factors (such as tobacco use; limited prenatal care; obesity; corticosteroid use; nulliparity; twin gestations; and previous CD), intrapartum and operative factors (such as chorioamnionitis; premature rupture of membranes; prolonged rupture of membranes; prolonged labor, particularly prolonged second stage; large incision length; subcutaneous tissue thickness > 3 cm; subcutaneous hematoma; lack of antibiotic prophylaxis; emergency delivery; and excessive blood loss), and obstetrical care on the teaching service of an academic institution. Effective interventions to decrease surgical site infection include prophylactic antibiotic use (preoperative first generation cephalosporin and intravenous azithromycin), chlorhexidine skin preparation instead of iodine, hair removal using clippers instead of razors, vaginal cleansing by povidone-iodine, placental removal by traction of the umbilical cord instead of by manual removal, suture closure of subcutaneous tissue if the wound thickness is >2 cm, and skin closure with sutures instead of with staples. Implementation of surgical bundles in non-obstetric patients has been promising., Creating a similar patient care bundle comprised evidence-based elements in patients who undergo CD may decrease the incidence of this major complication. Each hospital has the opportunity to create its own CD surgical bundle to decrease surgical site infection.

Abstract
Surgical site infection (SSI) is one of the most common complications following cesarean section, and has an incidence of 3%-15%. It places physical and emotional burdens on the mother herself and a significant financial burden on the health care system. Moreover, SSI is associated with a maternal mortality rate of up to 3%. With the global increase in cesarean section rate, it is expected that the occurrence of SSI will increase in parallel, hence its clinical significance. Given its substantial implications, recognizing the consequences and developing strategies to diagnose, prevent, and treat SSI are essential for reducing postcesarean morbidity and mortality. Optimization of maternal comorbidities, appropriate antibiotic prophylaxis, and evidence-based surgical techniques are some of the practices proven to be effective in reducing the incidence of SSI. In this review, we describe the biological mechanism of SSI and risk factors for its occurrence and summarize recent key clinical trials investigating preoperative, intraoperative, and postoperative practices to reduce SSI incidence. It is prudent that the surgical team who perform cesarean sections be familiar with these practices and apply them as needed to minimize maternal morbidity and mortality related to SSI.

Abstract
BACKGROUND Prophylactic administration of antibiotics preceding cesarean delivery is the most effective measure taken for preventing postpartum infection. While obese women are at greater risk for infection than non-obese women, evidence-based recommendations for modifying dosing in these women are limited. OBJECTIVES The purpose of this study was to determine whether obese women undergoing cesarean delivery similarly reach adequate cefazolin concentrations within tissue and blood when weighing <120kg and dosed 2g versus weighing ≥120kg and dosed 3g. STUDY DESIGN We prospectively studied women ≥18 years old with body mass index ≥30kg/m2 who underwent scheduled cesarean delivery with singleton pregnancy from August 2014 through March 2016. Women were dosed with 2g and 3g of cefazolin for body weights <120kg and ≥120kg, respectively. Samples of subcutaneous adipose tissue (following skin incision and before skin closure), myometrial tissue, fetal cord blood, and maternal blood were collected to assess whether cefazolin concentrations were adequate, i.e., at/above the minimum inhibitory concentration (MIC). Concentrations, based on inhibition zones for Streptococcus sanguinis, were calculated per gram of solid tissue and milliliter of blood. For all sample types, log-transformed concentrations were compared between dosage groups. Using a range of published MICs (1-8μg/mL or μg/g), odds ratios, describing differential odds of falling below the MIC between dosage groups, were also computed. RESULTS Women who received 2g (n=65) versus 3g (n=19) of cefazolin did not significantly differ by maternal or gestational age, race/ethnicity, pre-operative hemoglobin, estimated blood loss, fluid administration, duration of surgery, or timing of sample collections relative to cefazolin administration (Ps>0.05). Dosage groups also did not differ in cefazolin concentration (median [interquartile range]) within adipose tissue following skin incision (5.30μg/g [3.00-9.60] vs. 6.35μg/g [3.90-8.40]; P=0.551), adipose tissue before skin closure (4.45μg/g [2.78-7.25] vs. 6.90μg/g [2.60-10.6]; P=0.342), myometrial tissue (13.1μg/g [8.60-19.6] vs. 15.7μg/g [10.8-21.7]; P=0.116), or maternal blood (41.6μg/mL [26.3-57.0] vs. 45.3μg/mL [36.7-68.3]; P=0.143). However, cord blood concentrations differed significantly (19.5μg/mL [13.7-28.5] vs. 27.9μg/mL [15.8-39.4]; P=0.032), and, in 3 of 5 sample types, group concentrations differed at the dosing cut-point of 120kg (Ps<0.02). Within the range of MICs considered, differences in the odds of concentration inadequacy were not detected between dosage groups for any sample type. Across all patients, inadequate concentrations in one or more solid tissue types were observed in 1.19%, 17.9%, 59.5%, and 86.9% of patients, given the MICs of 1μg/g, 2μg/g, 4μg/g and 8μg/g, respectively. In adipose tissues, specifically, and both dosage groups, mean concentrations were significantly lower than the MIC of 8μg/g (Ps<0.03). Concentrations in one or both blood sample types were inadequate for only 8.33% of patients, given the 8-μg/mL MIC. CONCLUSIONS Adequate cefazolin concentrations were achieved in blood for the majority of our patients. However, concentration adequacy was not achieved in solid tissue for a nearly equally large proportion of patients. Larger scale studies for determining modified protocols for dosing and applying MICs are warranted.

Reduction and sustainability of cesarean section surgical site infection: An evidence-based, innovative, and multidisciplinary quality improvement intervention bundle program. Am J Infect Control 2016; 44:1315-1320. [PMID: 27317407 DOI: 10.1016/j.ajic.2016.04.217] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2016] [Revised: 04/03/2016] [Accepted: 04/04/2016] [Indexed: 11/20/2022]
Abstract
BACKGROUND We found cesarean section (C-section) surgical site infection (SSI) at our institution was significantly higher than the national benchmark. METHODS A retrospective cohort study was conducted under 4 phases from January 2008-December 2014. The hospital infection control (IC) policies and a presurgical checklist were bundled and implemented. The study was conducted with 3,334 cesarean deliveries: phase A (January 1, 2008-January 31,2010): 1,250 patients without intervention (baseline SSI rate), phase B (February 1, 2010-July 31, 2011): 682 patients were intervened with IC policies, phase C (August 1, 2011-December 31, 2012): 591 patients with an SSI reduction bundle, and phase D (January 1, 2013-December 31, 2014): 811 patients were monitored for C-section SSI sustainability. Patients not following strict protocols because of emergency C-section deliveries were excluded. The χ2 test, Fisher exact test, and standard Z test were used for statistical analyses. RESULTS C-section SSI rates were 6.2% (77/1,250) in phase A, 3.7% (25/682) in phase B, 1.7% (10/591) in phase C, and 0.1% (1/811) in phase D, respectively. By implementing the IC policies and bundle, the C-section SSI rate was reduced 40.3% (phase B vs phase A), 72.6% (phase C vs phase A), and 98.4% (phase D vs phase A). All statistics were significantly different. CONCLUSIONS We conclude that implementing a C-section SSI reduction bundle was associated with reduced C-section SSI rate down toward zero. A future prospectively randomized controlled trial is warranted.

Abstract
French and American guidelines recommend increased dosage regimens of cefazolin (CFZ) for surgical prophylaxis in patients with a body mass index (BMI) ≥ 35 kg/m2 or with a total body weight (TBW) ≥ 120 kg. The objective of this study was to evaluate the accuracy of these cut-offs in identifying patients who require CFZ dose adjustment. A pharmacokinetic study was conducted in patients of varying TBW and BMI who received 2 g of CFZ intravenously for prophylaxis prior to digestive surgery. Adequacy of therapy, defined as a serum concentration of unbound CFZ (fCFZ) ≥ 4 mg/L, was evaluated 180 min (T180) and 240 min (T240) after the start of CFZ infusion. Possible factors associated with insufficient fCFZ levels were also assessed. A P-value of <0.05 was considered statistically significant. A total of 63 patients were included in the study, categorised according to BMI (<35 kg/m2, 20 patients; and ≥35 kg/m2, 43 patients) and TBW (<120 kg, 41 patients; and ≥120 kg, 22 patients). All patients had adequate drug levels at T180 but only 40/63 patients (63%) had adequate levels at T240. At T240, therapy was adequate in 15/20 patients (75%) and 25/43 patients (58%) with BMI <35 kg/m2 and ≥35 kg/m2, respectively (P = 0.20), and in 28/41 patients (68%) and 12/22 patients (55%) with TBW <120 kg and ≥120 kg, respectively (P = 0.28). No factor associated with insufficient fCFZ was identified. In conclusion, current BMI and TBW cut-offs are poor indicators of which patients could benefit from increased CFZ dosage regimens.

Abstract
Obesity is a worldwide epidemic. It is associated with increased comorbidities and increased maternal, fetal, and neonatal complications. The risk of cesarean delivery is also increased in obese parturients. Anesthetic management of the obese parturient is challenging and requires adequate planning. Therefore, those patients should be referred to antenatal anesthetic consultation. Anesthesia-related complications and maternal mortality are increased in this patient population. The risk of difficult intubation is increased in obese patients. Neuraxial techniques are the preferred anesthetic techniques for cesarean delivery in obese parturients but can be technically challenging. An existing labor epidural catheter can be topped up for cesarean delivery. In patients who do not have a well-functioning labor epidural, a combined spinal epidural technique might be preferred over a single-shot spinal technique since it is technically easier in obese parturients and allows for extending the duration of the block as required. A continuous spinal technique can also be considered. Studies suggest that there is no need to reduce the dose of spinal bupivacaine in the obese parturient, but there is little data about spinal dosing in super obese parturients. Intraoperatively, patients should be placed in a ramped position, with close monitoring of ventilation and hemodynamic status. Adequate postoperative analgesia is crucial to allow for early mobilization. This can be achieved using a multimodal regimen incorporating neuraxial morphine (with appropriate observations) with scheduled nonsteroidal anti-inflammatory drugs and acetaminophen. Thromboprophylaxis is also important in this patient population due to the increased risk of thromboembolic complications. These patients should be monitored carefully in the postoperative period, since there is increased risk of postoperative complications in the morbidly obese parturients.
