Abstract
Cerebrospinal fluid (CSF) shunts are commonly used for the long-term management of hydrocephalus in children. Shunt infection remains a common complication, occurring in about 5%-15% of CSF shunts. This narrative review summarises key evidence from recent literature on the epidemiology, pathogenesis, clinical presentation, diagnosis, management, outcomes and prevention of CSF shunt infections in children. The majority of shunt infections occur due to contamination at the time of surgery, with coagulase-negative staphylococci and Staphylococcus aureus being the most common infecting organisms. Clinical presentations of shunt infection can be varied and difficult to recognise. CSF cultures are the primary test used for diagnosis. Other CSF and blood parameters may aid in diagnosis but lack sensitivity and specificity. Core aspects of management of shunt infections include systemic antimicrobial therapy and surgical removal of the shunt. However, many specific treatment recommendations are limited by a lack of robust evidence from large studies or controlled trials. Shunt infections may result in long hospital stays, worsening hydrocephalus, neurological sequelae and other complications, as well as death. Therefore, reducing the incidence of infection and optimising management are high priorities. Antibiotic prophylaxis at the time of shunt placement, improved surgical protocols and antibiotic-impregnated shunts are key strategies to prevent shunt infections. Nevertheless, further work is needed to identify additional strategies to prevent complications and improve outcomes.

[PMID: 36761915 PMCID: PMC9902906 DOI: 10.3389/fneur.2022.1023761] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2022] [Accepted: 12/31/2022] [Indexed: 01/25/2023] Open
Abstract
Objective To identify the relationship between preoperative cerebrospinal fluid (CSF) leukocyte, chloride, glucose, aspartate aminotransferase, lactate dehydrogenase, adenosine deaminase, lactic acid and protein levels and ventriculoperitoneal shunt infection. Methods Records of 671 consecutive adult patients who underwent ventriculoperitoneal shunt surgery for the treatment of hydrocephalus at Zhujiang Hospital affiliated with Southern Medical University from January 2011 to March 2022 were reviewed. The patients were divided into infection and non-infection groups based on the presence of postoperative infection. For all patients, we analyzed age; sex; primary disease; preoperative CSF leukocyte, chloride, glucose, aspartate aminotransferase, lactate dehydrogenase, adenosine deaminase, lactic acid and protein levels; postoperative temperature; and postoperative infection. Results A total of 397 patients were included, 28 (7.05%) of whom had an infection within 6 months of the operation and the remaining had no infection. There was no significant difference in age, sex, primary disease, leukocyte, chloride ion, aspartate aminotransferase, lactate dehydrogenase, adenosine deaminase and protein levels in CSF between infection group and non-infection group (p > 0.05). The postoperative infection rate of patients with CSF glucose < 2.8 mmol/L (x 2 = 11.650, p = 0.001) and CSF lactic acid >2.8 mmol/L (x 2 = 12.455, p < 0.001) was higher than that of patients with CSF glucose level ≥2.8 mmol/L and CSF lactic acid level in the range of (1-2.8) mmol/L, respectively, with statistical difference. Compared with the non-infection group, the level of CSF glucose (t = 4.113, p < 0.001) was significantly lower, and the level of CSF lactic acid (t = 6.651, p < 0.001) was significantly higher in the infection group. Multivariate logistic regression analysis showed that preoperative cerebrospinal fluid glucose < 2.8 mmol/L (OR = 3.911, 95% CI: 1.653~9.253, p = 0.002) and cerebrospinal fluid lactate >2.8 mmol/L (OR = 4.712, 95% CI: 1.892~11.734, p = 0.001) are risk factors for infection after ventriculoperitoneal shunt. ROC analysis revealed that the area under the curve (AUC) for CSF glucose and lactic acid level were 0.602 (95% CI: 0.492-0.713) and 0.818 (95% CI: 0.738-0.898), respectively. The infection group had higher rates of fever and body temperature on postoperative day 3-7 (p < 0.05). Conclusions For adult hydrocephalus patients without clinical manifestations of intracranial infection but only with simple abnormality of cerebrospinal fluid, when the content of glucose in cerebrospinal fluid is < 2.8 mmol/L, and the content of lactic acid is >2.8 mmol/L, it is recommended to perform ventriculoperitoneal shunt after further improvement of cerebrospinal fluid indicators, otherwise, hasty operation will increase the postoperative infection rate. The postoperative fever rate of ventriculoperitoneal shunt surgery is high and the body temperature drops rapidly. If there is still fever after day 3 after surgery, whether there is intracranial infection should be considered.

Abstract
BACKGROUND The aim of this study was to identify independent risk factors for cerebrospinal fluid shunt infection. METHODS The medical records of all patients aged 0-18 years who underwent shunt-related surgery for the treatment of hydrocephalus at the present institution between January 1996 and December 2015 were reviewed. For each case, two randomly selected controls with no shunt infection, matched for year of surgery, were chosen. Demographic clinical and microbiological data were abstracted. RESULTS A total of 1,570 shunt-related procedures met the inclusion criteria, yielding 68 infections (in 63 patients). The control group consisted of 132 infection-free patients. The average annual infection rate was 4.2% cases per year. The median time between shunt procedures to infection was 19 days (range, 1-2,181). On multivariate analysis, risk factors associated with increased risk for developing an infection included a history of two or more previous revisions (OR, 4.8; 95%CI: 1.5-15.9); and age <5 years (OR, 4.5; 95%CI 1.5-13.4). A neoplastic etiology for hydrocephalus was found to be a protective factor for shunt infection (P = 0.001). CONCLUSIONS A history of shunt revision was the most significant risk factor in the development of subsequent shunt infection. Age >5 years was a protective factor. Future efforts should focus on modalities to optimize revision procedures and reduce the risk of subsequent infection.

Abstract
PURPOSE Surgical antibiotic prophylaxis (SAP) in pediatric neurosurgery has poorly been characterized until now. This review gives an overview on the current literature extracting recommendations and guidelines. METHODS The current literature on SAP with special forcus on pediatric neurosurgerical procedures was reviewed. Further, available recommendations in online databases were checked. Clean neurosurgical, shunt, and implant surgeries are considered separately. RESULTS To date, evidence-based data on SAP in pediatric neurosurgery remain sparse and there are no standardized approaches to an adequate use of antimicrobial agents for SSI prevention for this age group. CONCLUSION Due to statistical needs, multi-center surveillance studies are needed for implementing SAP recommendations in pediatric neurosurgery.

Abstract
PURPOSE In this study, we investigate the occurrence rate of early shunt infection and malfunction in pediatric patients after converting an external ventricular drainage (EVD) to a ventriculo-peritoneal shunt (VPS) without replacing the ventricular catheter. METHODS Data was retrospectively reviewed for 17 pediatric patients (11 male (64.7%), mean age 7.5 years, range 0.25-15 years) who underwent 18 consecutive direct conversions of tunneled EVD to VPS without replacing the ventricular catheter between 2008 and 2017. In each case, the EVD was inserted in sterile fashion within the operating room and tunneled subcutaneously 5-7 cm away from the insertion site. Primary outcome measure was the occurrence of early (within 30 days) VPS infection or malfunction. The mean follow-up time was 56.8 months (±35.7 months). RESULTS The mean period of EVD before VPS placement was 9.0 days (±3.6 days, range 2-18 days). Five patients had shunt infections/malfunctions. One patient (5.6%) had an early shunt infection after 30 days. One patient had a late shunt infection after 9 months. One patient had an early shunt malfunction after 9 days. Two patients (11.1%) had late shunt malfunctions after 6.5 months and 9 years. There were no other incidents of shunt-related complications or shunt-related mortality. CONCLUSION In the pediatric population, the conversion of a tunneled EVD to a VPS without replacing the ventricular catheter can be safely done. Cranial entry is spared, while the rates of shunt infection and malfunction do not increase significantly.

Abstract
Shunt infection is a morbid complication of cerebrospinal fluid (CSF) shunting. The catheters with a hydrophilic surface may impede bacterial adherence and thereby reduce catheter-related CSF infection.A retrospective study compared the occurrence of CSF infection related to use of either standard silastic catheters or hydrogel-coated ventricular catheters (Bioglide, Medtronic). The enrolment was available to neurosurgery patients undergoing shunt surgery from October 2012 to 2015 in two centers. The follow-up period was more than months.A total of 78 patients were included in the study. In 33 patients 35-cm hydrogel-coated ventricular peritoneum shunts (VPS) were used, and in remaining 45 patients 35-cm standard silastic VPS catheters were used. Infection occurred in 14 (17.9%) patients, including definite VPS-related CSF infection in 6 patients (7.7%) and probable infection in remaining 8 patients (10.3%). There was a significant difference found in patients with total infection between the two groups [RR (95% CI); 0.200 (0.050-0.803), P = 0.014]. Analysis of Kaplan-Meier curve estimates indicated significant statistical difference between the two catheter types in duration (log rank = 4.204, P < 0.05). Significant statistical differences were also found in the subgroups including previous CSF infection within 1 month (log rank = 4.391, P = 0.04), conversion of external ventricular drains to shunt (Log Rank = 4.520, P = 0.03), and hospital stay >1 month (log rank = 5.252, P = 0.02). There was no difference found between the two groups of the patients with other infections within 1 month. The follow-up period was of 36 months.The hydrogel-coated catheter is a safe and related to lower infection rates for high-risk patients who underwent shunt surgery.

Abstract
BACKGROUND External ventricular drains (EVD) are commonly utilized for temporary diversion of cerebrospinal fluid (CSF). Many neurosurgeons prefer long-tunneled EVDs in their routine practice. However, it is still unclear whether this extended tunneling helps in reducing CSF infection. Keeping this in mind, we decided to compare infection rates in long-tunneled versus short-tunneled EVDs in the setting of a developing country. MATERIALS AND METHODS A prospective study of 60 patients was conducted. Consenting patients who underwent short-tunneled (Group A) or long-tunneled (Group B) EVDs between January 2008 and June 2009 were followed during the course of their inpatient care. All operational protocol was standardized during the trial. Serial samples of CSF were analyzed to detect infection. RESULTS Mean age of patients was 33.6 years with 32 males (53.3%). Mean duration of long-tunneled EVD was 13.4 ± 7.2 days, whereas that of short-tunneled EVD was 5.3 ± 2.7 days (P < 0.001). Three patients with long-tunneled EVD (10.0%), whereas one patient with short-tunneled EVD (3.3%) developed drain-related infections; however, this was non-significant (P = 0.301). However, patients with short-tunneled EVD got infected earlier on day 3when compared with the long-tunneled EVDs, which got infected after a mean duration of 7.3 days. The overall risk of infection for long-tunneled EVDs was 7.46 per 1,000 ventricular drainage days which was comparable to the risk of 6.33 per 1,000 ventricular drainage days seen for short-tunneled EVDs. CONCLUSION Long-tunneled EVDs appear to only delay potential infections without having any effect on the actual risk of infection. Long-tunneled EVD in a resource-limited setting is technically challenging and may not yield additional benefits to the patient. However, larger and prospective studies are needed to establish the rate of infections and other complications.

Abstract
OBJECTIVE The object of this study was to evaluate the clinical effectiveness of antibiotic prophylaxis in children who underwent placement of intracranial ventricular shunts. METHODS In this paper, the authors report a systematic review and meta-analysis of infection rate for pediatric shunt implantation surgery. Randomized or non-randomized controlled trials for comparing the use of prophylactic antibiotics in intracranial ventricular shunt procedures with placebo or no antibiotics were included in the review. RESULTS Seven published reports of eligible studies involving 694 participants meet the inclusion criteria. Compared with the control group, antibiotic prophylaxis had made a significant difference in infection rate (RR = 0.59, 95% CI = 0.38, 0.90, P < 0.05). CONCLUSION Although current evidence demonstrates that antibiotic prophylaxis can lead to a significant reduction of the infection rate of shunt surgery, more evidence from advanced multi-center studies is needed to provide instruction for the use of prophylactic antibiotics.

Abstract
OBJECT The objective of this systematic review and meta-analysis was twofold: to answer the question "What is the evidence for the effectiveness of prophylactic intravenous antibiotics for infection prevention in shunt surgery?" and to make treatment recommendations based on the available evidence. METHODS The US National Library of Medicine PubMed/MEDLINE database and the Cochrane Database of Systematic Reviews were queried using MeSH headings and key words relevant to prophylactic antibiotic use in children undergoing a shunt operation. Abstracts were reviewed to identify which studies met the inclusion criteria. An evidentiary table was assembled summarizing the studies and the quality of evidence (Classes I-III). A meta-analysis was conducted using a random-effects model to calculate a cumulative estimate of treatment effect using risk ratio (RR). Heterogeneity was assessed using chi-square and I(2) statistics. A sensitivity analysis was also conducted. Based on the quality of the literature and the result of the meta-analysis, a recommendation was rendered (Level I, II, or III). RESULTS Nine studies (4 Class I, 3 Class II, and 2 Class III) met our inclusion criteria. Of 7 randomized controlled trials (RCTs), 3 were downgraded from Class I to Class II because of significant quality issues, and all RCTs were potentially underpowered. In only 2 Class in retrospective cohort studies were preoperative antibiotic agents found to be protective against shunt infection. When data from the individual studies were pooled together, the infection rate in the prophylactic antibiotics group was 5.9% compared with 10.7% in the control group. Using a random-effects model, the cumulative RR was 0.55 (95% CI 0.38-0.81), indicating a protective benefit of prophylactic preoperative intravenous antibiotics. A sensitivity analysis of RCTs only (n = 7) also demonstrated a statistical benefit, but an analysis of higher-quality RCTs only (n = 4) did not. Conclusions Within the limits of this systematic review and meta-analysis, administration of preoperative antibiotic agents for shunt surgery in children was found to lower the infection risk (quality of evidence: Class II; strength of recommendation, Level II). RECOMMENDATION The use of preoperative antibiotic agents can be recommended to prevent shunt infection in patients with hydrocephalus. It was only by combining the results of the various underpowered studies (meta-analysis) that the use of preoperative antibiotics for shunt surgery in children was shown to lower the risk of shunt infection. STRENGTH OF RECOMMENDATION Level II, moderate degree of clinical certainty.

Abstract
Intrathecal baclofen has become an invaluable tool to treat spasticity of various etiologies. Children who benefit from intrathecal baclofen are often significantly underweight due to underlying disease pathology, and they lack adequate soft-tissue mass to effectively provide cover to the pump. Thus, in this population, subfascial implantation is favored over the subcutaneous technique in view of the high frequency of wound dehiscence and subsequent explantation of the pump associated with the latter method. The authors describe and review their unit's adapted subfascial implantation technique that has been performed over a period of 10 years in 182 children. This technique provides better tissue coverage for the pump and has resulted in lowering the risk of complications as compared with the subcutaneous technique.

Abstract
OBJECTIVE The objective of this study was to evaluate whether the rigid application of a sterile protocol for shunt placement was applicable on a routine basis and allowed the reduction of shunt infections (SI) in children. MATERIALS AND METHODS Since 2001, a rigid sterile protocol for shunt placement in children using neither antibiotic-impregnated catheters nor laminar airflow was prospectively applied at Erasme Hospital, Brussels, Belgium. For assessing the protocol efficacy before continuation, we preliminarily analyzed the results of the first 100 operated children (43 females, 57 males, 49 aged <12 months; 115 consecutive shunt placement/revision procedures). All procedures were performed by the same senior surgeon, one assistant, one circulating nurse, one anesthesiologist. The sterile protocol was rigidly imposed to these four staff members: uniformed surgical technique; limited implant and skin edge manipulation; minimized human circulation in the room; scheduling surgery as first morning operation; avoiding postoperative cerebrospinal fluid (CSF) leak; double gloving; procedures of less than 30-min duration; systemic antibiotics prophylaxis. We analyzed separately: (1) children carrying an increased risk of SI (n = 38) due to preoperative external ventricular drainage, CSF leak, meningitis, glucocorticoids, chemotherapy; (2) children aged <12 months; (3) procedures for shunt revision. RESULTS Errors in protocol application were recorded in 71/115 procedures. They were mainly done by non-surgical staff, decreased with time and were medically justified in some young children. Surprisingly, no SI occurred (follow-up, 4 to 70 months). One child developed an appendicitis with peritonitis (Streptococcus faecalis) after 6 months. No SI was found. After peritonitis was cured, shunt reinsertion was uneventful. CONCLUSION These preliminary results suggest that a uniform and drastic sterile surgical technique for shunt placement: (1) can be rigidly applied on a routine basis; (2) can lower the early SI rate below 1%; (3) might have a stronger impact to reduce SI than using antibiotic-impregnated catheters and optimizing the operative environment such as using laminar airflow and reducing the non-surgical staff. This last issue will be evaluated further in the present ongoing protocol.
