Powder Topical Rifampin for Reducing Infections After Neural Tube Defect Surgery in Infants

Retrospective Examination of Infants With Congenital Neural Tube Defect

INTRODUCTION

In the present study, neonates presenting with neural tube defects (NTDs) and undergoing observation within the confines of the neonatal intensive care unit (NICU) were subjected to a comprehensive assessment encompassing concurrent morbidities, clinical manifestations, laboratory parameters, and instituted interventions.

MATERIALS AND METHODS

A retrospective examination was conducted on the medical records of 135 neonates diagnosed with congenital NTD within the temporal span from 2008 to 2018. The study cohort was drawn from the NICU of the Health Sciences University Erzurum Regional and Research Hospital Health Practice and Research Center.

DISCUSSION

The current investigation encompasses a retrospective analysis of 135 patients diagnosed with NTD who received treatment at the NICU between the years 2008 and 2018. Among these, 74 individuals (54.2%) were male, while 61 (45.8%) were female. Maternal ages ranged from 17 to 46 years, with variations in the number of pregnancies, ranging from 1 to 10. Notably, 71 cases (52.6%) were delivered through normal spontaneous delivery, whereas 64 cases (47.4%) underwent cesarean section. The familial context revealed that five patients (3.6%) had siblings with a history of NTD, while no instances were noted where mothers had received antenatal folic acid support. Birth weights of the neonates ranged from 1425 to 4500 grams. Consanguinity was identified in the parental relationships of 17 cases (12.6%). The average diameter of the neural tube sac was determined to be 4.83 ± 1.94 cm (1-12 cm). Predominantly, the lumbosacral region emerged as the most common site of NTD, with meningomyelocele being the prevailing NTD type. Hydrocephalus coexisted in 67 cases, and notably, 44 instances exhibited the development of hydrocephalus post-sac operation. Eight patients were deemed inoperable, and the initial surgery transpired at an average age of 4.3 ± 2.6 (0-17) days. Flap closure constituted 32 of the surgical interventions, while primary closure was implemented in 95 cases. Neurogenic bladder antedated the operation in 14 patients, and 12 individuals developed neurogenic bladder postoperatively. Ventriculoperitoneal shunt placement was warranted in 47 patients. The average duration of hospitalization was 22.5 ± 14.4 days. Regrettably, three patients died due to complications and infections during their hospital stay.

RESULT

NTD represents a significant cohort of pathologies necessitating a comprehensive and interdisciplinary management strategy. These anomalies are characterized by elevated morbidity and mortality rates, not only exerting substantial financial strains on societal, familial, and state healthcare resources but also inflicting profound emotional distress upon affected families. Crucially, periconceptional strategies emphasizing balanced nutrition coupled with targeted multivitamin and mineral supplementation, particularly the inclusion of folic acid, assume paramount importance in the prophylaxis of this debilitating condition.

Subcutaneous irrigation with rifampicin vs. povidone-iodine for the prevention of incisional surgical site infections following caesarean section: a prospective, randomised, controlled trial

The aim is to investigate the effect of irrigation of subcutaneous tissue with saline, rifampicin, or povidone-iodine on incisional surgical site infections following caesarean section. Three hundred patients scheduled for caesarean section were randomly assigned into one of three groups of 100 members each, as follows: the subcutaneous tissue was irrigated with saline in group 1 (control); saline + rifampicin in group 2; saline + 10% povidone-iodine in group 3. Patients who developed a superficial incisional surgical site infection within 30 days were recorded. The surgical site infection rate did not differ when using rifampicin or povidone-iodine (p = .202). It was observed that there was a statistically significant increase in the rate of incisional surgical site infections as the existence of comorbidities (p = .001), perioperative blood transfusion (p = .020), and midline incision (p = .004). Irrigation of subcutaneous tissue with rifampicin or 10% povidone-iodine is not effective in preventing surgical site infections after caesarean section.IMPACT STATEMENTWhat is already known on this subject? An increase has recently been observed in the incidence of SSI particularly in caesarean sections due to reasons, such as that elderly mothers are more commonly operated on compared to the past and long and complicated operations (Lachiewicz et al. 2015) and there are no clear decisions on measures to be taken. Also, there are not many studies on this subject (De Nardo et al. 2016; Solomkin et al. 2017).What do the results of this study add? In our study, we investigated the effectiveness of subcutaneous agents that have been used by many surgeons for years and we've revealed that it's not effective. There is no study in the literature comparing 3 different irrigation agents as we did in our study. For this reason, we think that we will make an important contribution to the measures to be taken in this important issue.What are the implications of these findings for clinical practice and/or further research? This study may contribute to reaching a sufficient level of evidence on surgical wound infections after caesarean sections, which are still missing in the literature, and that may be guiding for the studies that will be conducted on this subject in the future.

Epidemiology, Pathophysiology, and Management Strategies of Neonatal Wound Care

Guidelines for neonatal skin care are scarce, and there is no consensus on the best management practices for neonatal skin breakdown. This review presents the pathology and phases of wound healing, reasons for neonatal skin fragility, and approaches to recognition of commonly encountered neonatal wounds. This review also provides general strategies for neonatal wound prevention, care, dressing, and management to avoid further damage to the fragile neonatal skin. The importance and role of retaining moisture in expediting wound healing is discussed, as well as updated classifications on how to grade and assess pressure ulcers and the role of negative pressure wound therapy and silver dressings. Lastly, this review discusses prevention and treatment options for surgical wounds, intravenous extravasation wounds, congenital wounds, and thermal injuries, in addition to how to differentiate these wounds from the common diaper dermatitis and contact dermatitis.

Efficiency of Topical Rifampin on Infection in Open Neural Tube Defects: A randomized controlled trial

Objectives: Neural tube defects are the second most common congenital malformation in humans. Despite significant decreases in neural tube defects and related mortality and morbidity with recent developments, infections remain an important problem. Research on the role of topical therapy for managing neural tube defects and associated infections in the neonatal period has been limited. This randomized controlled trial aimed to investigate the efficiency of topical Rifampin on infection control in paraplegic newborns with open neural tube defects.Methods: Thirty-seven patients who underwent an operation for neural tube defects were included. Topical Rifampin and cefotaxime were administered to 19 patients constituting the case group and local saline and cefotaxime were administered to a control group. Patients were examined for ventriculoperitoneal shunt infection/dysfunction, surgical site infection, urinary tract infection, and sepsis.Results: None of the patients using topical rifampin had ventriculoperitoneal shunt infection/dysfunction, surgical site infection, urinary tract infection, or sepsis. In the control group, ventriculoperitoneal shunt infection/dysfunction was found in 4 (22.2%) cases, surgical site infection in 3 (27.7%), urinary tract infection in 3 (27.7%), and sepsis in 5 (27.7%), with statistically significant differences between the groups (p = 0.01, p = 0.032, p = 0.032, and p = 0.002, respectively). No local or systemic side effect was observed regarding rifampin use.Conclusion: Topical Rifampin is effective in minimizing complications like sepsis, surgical site infection, urinary tract infection, and ventriculoperitoneal shunt infection due to neural tube defect operations. Further research with larger numbers of cases is needed to implement this practice routinely.

Reduced rates of infection after myelomeningocele closure associated with standard perioperative antibiotic treatment with ampicillin and gentamicin

PURPOSE

Postnatal closure of a myelomeningocele (MMC) is a complex procedure with frequent complications following surgery. Bacterial colonization of the placode may cause infection and subsequent complications. The objectives of this study were to determine the preoperative bacterial colonization rates, to assess the antibiotic regimen, and to evaluate the overall postoperative infection rate.

METHODS

All consecutive patients undergoing MMC closure in our hospital from January 2010 to January 2020 were evaluated. Epidemiological data, surgical data, complication characteristics, and microbiological results were documented.

RESULTS

A total of 45 patients were evaluated; in 41 patients, a wound swab of the placode was performed directly before MMC closure (91%). All patients received a prophylactic antibiotic treatment for a mean of 5.6 ± 2.7 days around the performed MMC closure. In three patients with a wound swab (7.3%), a bacterial colonization could be detected-none of the patients developed a subsequent infection. Overall, 7 other patients developed an infection (15.6%), three local surgical site infections, and four shunt-related infections. After applying a standardized perioperative prophylactic antibiotic treatment with ampicillin and gentamicin, the infection rate was observed to be lower compared with that of a non-standardized treatment (6% vs. 45%; p = 0.019).

CONCLUSIONS

In neonates who undergo MMC closure in the first 48 h after birth, the colonization rate of the placode was lower than previously reported. While the data presented cannot proof the benefit of a perioperative antibiotic prophylaxis, as compared with no prophylaxis, infection rates are low with a standardized antibiotic regime comprising ampicillin and gentamicin.
