Abstract
OBJECTIVE To reduce surgical site infections (SSIs) after cesarean birth through a bundled care approach. DESIGN Quality improvement project. SETTING/LOCAL PROBLEM In a community hospital obstetric unit, an increase in SSIs after cesarean birth was observed. PARTICIPANTS Nursing leaders, obstetricians, certified nurse-midwives, physician assistants, nurses, scrub technicians, a nursing professional development specialist, and an infection prevention practitioner. INTERVENTIONS/MEASURES An interdisciplinary team was formed in early 2022, and an evidence-based care bundle including practice changes, education for the team, and enhanced education for patients undergoing cesarean birth was developed and implemented after a review of the literature was completed. All cesarean births were tracked pre- and postintervention to determine the rate of SSIs per 1,000 cesarean births. RESULTS A decrease in the rate of SSIs after cesarean birth was observed from preintervention (18.2 per 1,000 cesarean births) to postintervention (11.8 per 1,000 cesarean births). CONCLUSION An evidence-based quality improvement care bundle using a multidisciplinary team approach was associated with reduced SSIs in an obstetric unit.

Abstract
Subcutaneous (SC) saline irrigation was reported as a feasible and cost-effective procedure to prevent cesarean section (CS) surgical site complications. We aim to investigate the efficacy of SC saline irrigation to prevent CS surgical site complications. A systematic review and meta-analysis were conducted synthesizing evidence from randomized controlled trial (RCT) studies obtained from PubMed, Embase Cochrane, Scopus, and Web of Science from inception to March 2024. Pooled outcomes included wound complications (superficial surgical site infections (SSI), hematoma, seroma, and wound separation) and operative time. We used RevMan v.5.4. (The Cochrane Collaboration, Oxford, UK) to report dichotomous outcomes using risk ratio (RR) and continuous outcomes using mean differences (MD) with a 95% confidence interval (CI). Five RCTs with 4,025 patients were included. Four studies had a low overall risk of bias and only one trial with some concerns about selection bias. There was no difference between SC saline irrigation and no irrigation regarding the incidence of superficial SSI (five RCTs, RR: 0.72 with 95% CI [0.47, 1.10], P = 0.13), seroma (four RCTs, RR: 0.73 with 95% CI [0.32, 1.65], P = 0.45), wound separation (four RCTs, RR: 0.66 with 95% CI [0.36, 1.24], P = 0.2), and operative time (four RCTs, MD: -1.26 with 95% CI [-5.14, 2.62], P = 0.52). However, SC saline irrigation significantly decreased the incidence of hematoma (three RCTs, RR: 0.54 with 95% CI [0.45, 0.65], P = 0.00001). SC saline irrigation of the surgical site after CS was not effective in preventing the incidence of superficial SSI, seroma, or wound separation, while only preventing the incidence of hematoma.

Abstract
This paper aims to evaluate whether there is a device-dependent effect on the reduction of surgical site complications in obese patients (body mass index [BMI] ≥ 30 kg/m2) undergoing cesarean section (C-section). PubMed, Embase, Cochrane Library, and ClinicalTrials.gov were searched for the period, January 2011 to September 2021. English language articles describing a randomized controlled trial (RCT) that compared either a -80 or -125 mm Hg single-use negative pressure wound therapy (sNPWT) device to standard dressings in obese (BMI ≥ 30 kg/m2) patients undergoing C-section were included. Conference abstracts and "terminated" RCTs with published results were deemed eligible for inclusion. The primary outcome of interest was surgical site infection (SSI), classified as composite, superficial, or deep. Secondary outcomes assessed included seroma, dehiscence, hematoma, bleeding, reoperation, readmission, blistering, and (composite) wound complications. A total of 223 titles were identified, of which 129 were screened by full-text review. Eleven RCTs encompassing 5,847 patients met the inclusion criteria and were considered eligible for further analysis (-80 mm Hg: six studies; -125 mm Hg: five studies). A statistically significant improvement in the composite SSI (odds ratio [OR]: 0.69; 95% confidence interval [CI]: 0.54-0.89) and superficial SSI (OR: 0.66; 95% CI: 0.50-0.86) outcomes was observed with the -80 mm Hg device, compared with standard dressings. The same effect on SSI outcomes was not observed with the -125 mm Hg device (composite SSI-OR: 0.91; 95% CI: 0.64-1.28; superficial SSI-OR: 1.12; 95% CI: 0.70-1.78). There were no statistically significant differences in any of the other assessed outcomes. sNPWT devices may differ in their ability to reduce composite or superficial SSI after C-section. KEY POINTS: · Negative pressure benefits obese patients undergoing C-section.. · Negative pressure devices may differ in performance.. · A head-to-head clinical trial is needed..

J Matern Fetal Neonatal Med 2023; 36:2222208. [PMID: 37332139 DOI: 10.1080/14767058.2023.2222208] [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: 04/12/2022] [Revised: 12/20/2022] [Accepted: 06/01/2023] [Indexed: 06/20/2023]
Abstract
OBJECTIVE Maternal glycemia is associated with the risk of cesarean delivery (CD); therefore, our study aims to developed a prediction model based on glucose indicators in the second trimester to earlier identify the risk of CD. METHODS This was a nested case-control study, and data were collected from the 5th Central Hospital of Tianjin (training set) and Changzhou Second People's Hospital (testing set) from 2020 to 2021. Variables with significant difference in training set were incorporated to develop the random forest model. Model performance was assessed by calculating the area under the curve (AUC) and Komogorov-Smirnoff (KS), as well as accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). RESULTS A total of 504 eligible women were enrolled; of these, 169 underwent CD. Pre-pregnancy body mass index (BMI), first pregnancy, history of full-term birth, history of livebirth, 1 h plasma glucose (1hPG), glycosylated hemoglobin (HbA1c), fasting plasma glucose (FPG), and 2 h plasma glucose (2hPG) were used to develop the model. The model showed a good performance, with an AUC of 0.852 [95% confidence interval (CI): 0.809-0.895]. The pre-pregnancy BMI, 1hPG, 2hPG, HbA1c, and FPG were identifies as the more significant predictors. External validation confirmed the good performance of our model, with an AUC of 0.734 (95%CI: 0.664-0.804). CONCLUSIONS Our model based on glucose indicators in the second trimester performed well to predict the risk of CD, which may reach the earlier identification of CD risk and may be beneficial to make interventions in time to decrease the risk of CD.

Abstract
OBJECTIVE The objective of this study was to compare maternal outcomes of women with and without severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections who underwent cesarean births. STUDY DESIGN This was a matched cohort study of pregnant women who had a cesarean birth between March 15, 2020, and May 20, 2020. Cases included women who tested positive for SARS-CoV-2. For every case, two patients who tested negative for SARS-CoV-2 were matched by maternal age, gestational age, body mass index, primary or repeat cesarean birth, and whether the procedure was scheduled or unscheduled. We compared rates of adverse postcesarean complications (intraoperative bladder or bowel injury, estimated blood loss more than or equal to 1,000 mL, hemoglobin drop more than 3 g/dL, hematocrit drop more than 10%, need for blood transfusion, need for hysterectomy, maternal intensive care unit admission, postoperative fever, and development of surgical site infection), with the primary outcome being a composite of those outcomes. We also assessed duration of postoperative stay. Fisher's exact tests were performed to compare the primary outcome between both groups. RESULTS Between March and May 2020, 202 women who subsequently underwent cesarean birth were tested for SARS-CoV-2. Of those 202, 43 (21.3%) patients were positive. They were matched to 86 patients who tested negative. There was no significant difference in the rate of composite adverse surgical outcomes between the groups (SARS-CoV-2 infected 27.9%, SARS-CoV-2 uninfected 25.6%; p = 0.833). There was a higher rate of postoperative fevers (20.9 vs. 5.8%; p = 0.015), but that did not result in a longer length of stay (p = 0.302). CONCLUSION Pregnant women with SARS-CoV-2 who underwent a cesarean birth did not have an increased risk of adverse surgical outcomes, other than fever, compared with pregnant women without SARS-CoV-2. KEY POINTS · Women with SARS-CoV-2 had more postoperative fevers.. · Length of stay did not differ based on SARS-CoV-2 status.. · Composite postoperative outcome did not differ based on SARS-CoV-2 status..

Abstract
Background Sepsis is a very serious complication of cesarean section, understanding the influencing factors is important to the prevention and management of sepsis. We aimed to analyze the associated risk factors of sepsis of cesarean section, to provide evidences into the clinical management and nursing care of cesarean section. Methods Patients who underwent cesarean section surgery from January 1, 2017 to June 30, 2021 in our hospital were included. The characteristics of patients were collected and analyzed. Logistic regression analyses were conducted to analyze the influencing factors of sepsis of cesarean section. Results A total of 3819 patients undergoing cesarean section were included, the incidence of sepsis in patients undergoing cesarean section was 0.84%. There were significant differences in the age, vaginal delivery attempt, premature rupture of membranes, preoperative hemoglobin, estimated blood loss during surgery and postoperative urinary tube implacement between sepsis and no sepsis patients (all p < 0.05). Logistic regression analyses found that age ≥ 35y(OR3.22, 95%CI1.20 ~ 5.15), gestational diabetes(OR2.64, 95%CI1.91 ~ 4.15), vaginal delivery attempt(OR2.05, 95%CI1.70 ~ 4.42), premature rupture of membranes(OR2.42, 95%CI1.02 ~ 4.20), preoperative hemoglobin ≤ 105 g/L(OR4.39, 95%CI1.02 ~ 7.88), estimated blood loss during surgery ≥ 400 ml(OR1.81, 95%CI1.35 ~ 3.01), postoperative urinary tube implacement(OR2.19, 95%CI1.27 ~ 2.50) were the risk factors of sepsis in patients undergoing cesarean section(all p < 0.05). Escherichia Coli(46.15%), Enterococcus faecalis(17.95%) and Pseudomonas aeruginosa(12.83%) were the most commonly-seen bacteria in sepsis patients. Conclusion In clinical practice, medical workers should carry out strict management and early prevention of related risk factors during the perioperative period of pregnant women, to effectively reduce the occurrence of sepsis after cesarean section.

Abstract
STUDY OBJECTIVE This study aimed to determine the modifiable risk factors associated with surgical site infection (SSI) after cesarean section in adolescent pregnant patients. DESIGN Retrospective case-control study SETTING: Department of Obstetrics and Gynecology, Tepecik Education and Research Hospital, Izmir, Turkey PARTICIPANTS: Pregnant adolescents (≤ 19 years) who underwent cesarean section at our institution between January 2014 and March 2021 INTERVENTIONS AND MAIN OUTCOME MEASURES: To determine the modifiable and nonmodifiable risk factors associated with SSI following cesarean section in adolescents. The diagnosis of SSI was made according to the criteria defined by the Centers for Disease Control and Prevention (CDC). RESULTS SSI was diagnosed in 62 (2.9%) of 2105 adolescent mothers who underwent cesarean section. Univariate and multivariate analyses confirmed that body mass index (BMI) (OR = 2.35; 95% CI, 1.3-4.78), induction of labor (OR = 1.9; 95% CI, 1.2-3.71), and preoperative hemoglobin values less than 10 g/dl (OR = 2.1; 95% CI, 1.2-4.46) were risk factors for SSI in adolescent mothers. Patient- and operation-related risk factors did not reach the level of statistical significance. CONCLUSIONS BMI, labor induction, and antenatal anemia were independent risk factors for SSI in adolescents. Among these, BMI and anemia were modifiable patient-related risk factors. Addressing obesity in adolescents and treating prenatal anemia could be the first steps toward preventing SSI.

Abstract
Background We aimed to determine the prevalence and risk factors of surgical site infection (SSI) after cesarean delivery (CD) in a rural area in China. Methods We identified 155 patients with incisional and organ/space SSIs by International Classification of Disease codes and matched them with 465 patients (controls) in a time-matched retrospective quality assurance analysis. Multiple logistic regression analyses were performed to examine the risk factors for SSI: the work-years of providers, the number of antenatal care (ANC) visits, CD after labor, positive discharge culture, postoperative C-reactive protein (CRP) levels and fever. Results and discussion: During the study, 155 women with SSI were identified among the 8640 patients who delivered by CD. The incidence of SSIs was 179 per 10 000patients (95%CI: 151–207 per 10 000 patients). The total duration of hospitalization in patients with SSI was 14.49 ± 8.68 days compared with 7.96 ± 2.35 days in patients with no SSI (P < 0.01). Multiple logistic regression analysis showed that the work-years of providers (odds ratio [OR] = 3.729, 95% confidence interval [CI]: 1.463–9.501, p = 0.006), irregular ANC visits (OR = 3.245, 95% CI: 1.264–8.329, p = 0.028), CD after labor (OR = 2.545, 95% CI: 0.935–6.926, p = 0.020), postoperative CRP level (OR = 2.545, 95% CI: 0.935–6.926, p = 0.016) and a positive discharge culture (OR = 2.954, 95% CI: 0.305–28.643, p = 0.019) were positively associated with SSI. However, the rates of maternal request (OR = 0.186, 95% CI: 0.065–0.535, p = 0.002) and postoperative fever (OR = 0.208, 95% CI: 0.087–0.494, p = 0.001) were negatively related to SSI. Conclusions Special attentions should be paid to CD patients who had irregular ANC visits, attempted labor, a positive discharge culture, higher CRP levels and fever after surgery, who had a greater risk of SSI. The incidence of SSIs was 179 per 10 000 patients (95%CI: 151–207). Risk factors of SSIs included: irregular ANC visits, a positive discharge culture. Higher CRP levels and fever after surgery had a greater risk of SSI.

Abstract
Background Surgical site infections after cesarean section are very common clinically, it is necessary to evaluate the risk factors of surgical site infections after cesarean section, to provide evidences for the treatment and nursing care of cesarean section. Methods This study was a retrospective cohort study design. Patients undergone cesarean section in a tertiary hospital of China from May 2017 to May 2020 were identified, we collected the clinical data of the included patients, and we analyzed the infection rate, etiological characteristics and related risk factors of surgical site infection after caesarean section. Results A total of 206 patients with cesarean section were included, and the incidence of surgical site infection in patients with cesarean section was 23.30%. A total of 62 cases of pathogens were identified, Enterococcus faecalis (33.87%) and Escherichia coli (29.03%) were the most common pathogens. Both Enterococcus faecalis and Escherichia coli were highly sensitive to Cefoperazone, Meropenem, and Levofloxacin. Logistic regression analyses indicated that Age ≥ 30y (OR 4.18, 95%CI: 1.23–7.09), BMI ≥ 24 (OR 2.39, 95%CI: 1.02–4.55), duration of cesarean section ≥ 1.5 h (OR 3.90, 95%CI: 1.28–5.42), estimated blood loss ≥ 400 ml (OR 2.35, 95%CI: 1.10–4.37) and the duration of urinary catheter ≥ 24 h (OR 3.18, 95% CI: 1.21–5.71) were the independent risk factors of surgical site infection after cesarean section (all p < 0.05). Conclusions Age, BMI, duration of surgery, blood loss and urinary catheter use were associated with higher risk of the surgical site infection after cesarean section. Clinical preventions and interventions are warranted for those population to reduce the occurrence of surgical site infection.

Abstract
BACKGROUND Penicillin and other beta-lactam antibiotics are recommended for group B Streptococcus and cesarean section prophylaxis, but approximately 10% of pregnant patients report a penicillin allergy. OBJECTIVE To assess the safety and impact of penicillin allergy evaluation in pregnant patients. METHODS In this retrospective study of obstetrician-ordered Allergy/Immunology (AI) electronic consultations (e-consults) from September 20, 2017 through December 31, 2019, we reviewed the electronic health record for e-consult recommendation; patient demographic, obstetric, and allergy histories; and peripartum antibiotic utilization with indication. For patients whose electronic consultation recommended an in-person AI evaluation, testing outcomes were determined, and multivariable logistic regression models were used to compare antibiotic use between patients who did and did not receive an in-person AI evaluation. RESULTS Of 389 obstetrician-ordered e-consults, 363 (93%) recommended an in-person AI evaluation; of these, 222 (61%) patients received an in-person AI evaluation. Of 220 (99%) patients skin tested, 209 (95%) had their penicillin allergy label safely removed. Compared with patients who did not receive an in-person AI evaluation despite it being recommended (n = 141), patients with in-person AI evaluation (n = 222) had reduced peripartum vancomycin (adjusted odds ratio [aOR], 0.07; 95% CI, 0.01-0.33), clindamycin (aOR, 0.17; 95% CI, 0.08-0.34), and gentamicin (aOR, 0.39; 95% CI, 0.19-0.78) use and increased penicillin (aOR, 18.0; 95% CI, 6.30-51.2) use. The fully AI evaluated patients had increased first-line antibiotic prophylaxis for group B Streptococcus (aOR, 26.9; 95% CI, 6.32-114) and cesarean section (aOR, 1.94; 95% CI, 1.06-3.52). CONCLUSIONS In a sample of 220 pregnant patients with penicillin allergy histories and in-person AI evaluation, penicillin allergy testing was safe and associated with significantly reduced broad-spectrum antibiotic use and increased first-line beta-lactam antibiotic use.

BMC Pregnancy Childbirth 2020; 20:606. [PMID: 33032560 PMCID: PMC7545895 DOI: 10.1186/s12884-020-03305-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2020] [Accepted: 09/30/2020] [Indexed: 01/28/2023] Open
Abstract
BACKGROUND Wound infection is a common complication following caesarean section. Factors influencing the risk of infection may include the suture material for skin closure, and closure of the subcutaneous fascia. We assessed the effect of skin closure with absorbable versus non-absorbable suture, and closure versus non-closure of the subcutaneous fascia on risk of wound infection following Caesarean section. METHODS Women undergoing caesarean birth at an Adelaide maternity hospital were eligible for recruitment to a randomised trial using a 2 × 2 factorial design. Women were randomised to either closure or non-closure of the subcutaneous fascia and to subcuticular skin closure with an absorbable or non-absorbable suture. Participants were randomised to each of the two interventions into one of 4 possible groups: Group 1 - non-absorbable skin suture and non-closure of the subcutaneous fascia; Group 2 - absorbable skin suture and non-closure of the subcutaneous fascia; Group 3 - non-absorbable skin suture and closure of the subcutaneous fascia; and Group 4 - absorbable skin suture and closure of the subcutaneous fascia. The primary outcomes were reported wound infection and wound haematoma or seroma within the first 30 days after birth. RESULTS A total of 851 women were recruited and randomised, with 849 women included in the analyses (Group 1: 216 women; Group 2: 212 women; Group 3: 212 women; Group 4: 211 women). In women who underwent fascia closure, there was a statistically significant increase in risk of wound infection within 30 days post-operatively for those who had skin closure with an absorbable suture (Group 4), compared with women who had skin closure with a non-absorbable suture (Group 3) (adjusted RR 2.17; 95% CI 1.05, 4.45; p = 0.035). There was no significant difference in risk of wound infection for absorbable vs non-absorbable sutures in women who did not undergo fascia closure. CONCLUSION The combination of subcutaneous fascia closure and skin closure with an absorbable suture may be associated with an increased risk of reported wound infection after caesarean section. TRIAL REGISTRATION Prospectively registered with the Australian and New Zealand Clinical Trials Registry, number ACTRN12608000143325 , on the 20th March, 2008.

Med Hypotheses 2019; 137:109532. [PMID: 31901609 DOI: 10.1016/j.mehy.2019.109532] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2019] [Revised: 11/29/2019] [Accepted: 12/15/2019] [Indexed: 02/04/2023]
Abstract
Cesarean delivery (CD) has been known as the most common surgery in the United States. This procedure might associate with different complications, the most important of which is surgical site infection (SSI). Among the major SSI categories, incisional type is more common than the others. Regardless of its notable expense, the use of prophylactic wound healing technics (such as negative pressure therapy) has been advised for the patients with high SSI risk. Herein, use of patient's own human amniotic membrane in an autologous form (as a free of charge treatment) would be suggested for prevention of SSI in CD wounds. Human amniotic membrane (hAM) has been used for treatment of acute and chronic wounds and shown to be able to reduce the infection and the pain along with accelerating the healing process. Moreover, it has been shown in a systematic review and meta-analysis that hAM could significantly improve the treatment rate in comparison to the standard of care dressing (RR 2.057-3.665, P < 0.001) during a set time of six weeks. Wound duration on the other hand, has been shown to negatively associate with SSI. Furthermore, there is data supporting the critical role of tissue perfusion in the acceleration of wound healing along with decreasing the rate of wound infection. Angiogenesis, the formation of new blood vessels from their existing capillaries, is among the most crucial pathways involved in increasing tissue perfusion and wound healing. Interestingly, hAM is a rich source of pro-angiogenic and other tissue growth factors with the ability of inducing angiogenesis as well as strong antibacterial peptides. Taken together, authors suggest autologous application of hAM in the high (even low) risk patients undergoing CD in order to decrease wound related complications such as SSI and accelerate the healing time as a free wound healer. However, further randomized clinical trials are necessary.
