Brief Summary

Objectives

  • Primary:
  • To measure the reduction in VP shunt infection rates using topical vancomycin powder.
  • Secondary:
  • To compare efficacy across different Etiological Strata (Congenital, Post-hemorrhagic, post-inflammatory).
  • To analyze the microbiological profile of failed cases.
  • To compare the "Time-to-Infection" and shunt survival rates between the study and control groups using Kaplan-Meier analysis.
  • To evaluate the cost-effectiveness of TVP compared to the standard management and historical AIC data

Outcome Measures

Primary Outcomes (1)

  • Incidence Rate of Ventriculoperitoneal (VP) Shunt Infections

    Evaluation of the efficacy of intraoperative topical Vancomycin powder in reducing the overall rate of shunt-related infections. Shunt infection will be defined based on: 1. Clinical signs (wound discharge, erythema, or peritonitis). 2. Laboratory findings (Positive CSF culture or abnormal CSF biochemistry). 3. radiological evidence of shunt failure 4. Surgical evidence (purulence during revision).

    Within 6 months postoperatively.

Secondary Outcomes (4)

  • Efficacy Analysis Stratified by Hydrocephalus Etiology

    Up to 6 months postoperatively

  • Time-to-Infection (Shunt Survival Rate).

    Up to 6 months postoperatively.

  • Microbiological Profile of Infected Shunts.

    At the time of infection diagnosis (within 6 months postoperatively).

  • Cost-Effectiveness Analysis of Topical Vancomycin Powder.

    Up to 6 months postoperatively.

Study Arms (2)

Topical Vancomycin Powder (TVP) Group

EXPERIMENTAL

Patients in this arm will undergo the standard surgical procedure for ventriculoperitoneal (VP) shunt insertion. In addition to standard perioperative intravenous (IV) antibiotic prophylaxis, sterile crystalline Vancomycin powder will be applied directly into Cranial Site (1/3): Around the reservoir and burr hole Tunnel Path (1/3): Dispersed along the subcutaneous track. Abdominal Site (1/3): At the peritoneal entry before closure.

Drug: Topical Vancomycin PowderProcedure: Standard Perioperative Care

Control Group

ACTIVE COMPARATOR

Patients in this arm will undergo the standard surgical procedure for ventriculoperitoneal (VP) shunt insertion with routine perioperative intravenous (IV) antibiotic prophylaxis only. No topical antibiotics will be applied during the procedure.

Procedure: Standard Perioperative Care

Interventions

Intraoperative Topical Vancomycin Application 1. Preparation and Material Pure vancomycin hydrochloride powder, sourced from conventional vials intended for intravenous reconstitution, will be utilized. The vials shall be opened under strictly sterile conditions within the operative field immediately prior to wound closure to ensure maximum potency and sterility. 2. Dosage Stratification To ensure therapeutic efficacy while maintaining a high safety profile, the dosage is stratified based on the patient's age and anatomical considerations: * Older Children (1 to 18 years): A standardized dose of 1 gram (1000 mg) will be applied. * Infants and Neonates (under 1 year): A weight-adjusted or reduced dose of 500 mg (0.5 grams) will be administered to accommodate the limited subgaleal and subcutaneous volume and to prevent potential local tissue irritation. 3. Application Technique (The "Dusting" Method) The application will follow a systematic "dusting" protocol to achieve a high

Also known as: Vancomycin Hydrochloride, TVP
Topical Vancomycin Powder (TVP) Group

"Patients receive the standard institutional protocol for VP shunt insertion, which includes preoperative and postoperative intravenous antibiotic prophylaxis and standard surgical technique without the application of topical antibiotic powder."

Eligibility Criteria

Age1 Day - 18 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Patients will be enrolled in the study if they meet all the following criteria:
  • Age Range: Paediatric patients from birth (neonates) up to 18 years of age.
  • Indication: Patients undergoing primary (first-time) Ventriculoperitoneal (VP) shunt insertion.
  • Aetiology: Hydrocephalus due to congenital causes, post-haemorrhagic, or post-inflammatory origins.
  • Consent: Written informed consent provided by the parents or legal guardians.

You may not qualify if:

  • To ensure that the infection rate is strictly related to the surgical procedure and not to external chronic factors, patients with the following will be excluded:
  • Tumor-related Hydrocephalus: Due to the impact of malignancy, chemotherapy-induced immunosuppression, or potential radiotherapy on wound integrity.
  • Co-morbidities: Patients with Diabetes Mellitus, chronic renal failure, or known immunodeficiency disorders (to isolate paediatric physiological response).
  • Active Infection: Clinical or laboratory evidence of systemic sepsis or meningitis at the time of surgery.
  • Hypersensitivity: Known history of allergy to Vancomycin.
  • Revision Surgery: Patients undergoing shunt revision or replacement due to previous infection within the last 3 months.
  • Local Skin Issues: Active dermatitis or infection at any of the planned incision sites.
  • Complex Hydrocephalus: Patients requiring additional concurrent neurosurgical procedures (e.g., tumor biopsy, Chiari decompression, or cyst fenestration) to avoid prolonged operative time as a confounding risk factor for infection."

Masking Details
"To minimize bias, this study employs a double-masking protocol. The Outcome Assessors, responsible for clinical and microbiological diagnosis of shunt infections, are blinded to the treatment allocation. Additionally, the Data Analysts/Statisticians will perform the comparative analysis using coded datasets without knowledge of group assignments. The surgical team (Investigators) cannot be blinded due to the nature of the intervention (topical application of powder). Randomization codes will be secured by a third party and only unblinded after the final statistical analysis is completed."
Purpose
PREVENTION
Intervention Model
PARALLEL
Model Details: \- Stratification \& Block Randomization To ensure a balanced baseline risk, patients will be stratified into three etiologic strata: 1. Stratum 1: Congenital Hydrocephalus. 2. Stratum 2: Post-haemorrhagic Hydrocephalus. 3. Stratum 3: Post-inflammatory (Post-meningitic) Hydrocephalus. Randomization Process: \> Within each stratum, patients will be randomly assigned to either the Control or Vancomycin group in a 1:1 ratio using Permuted Block Randomization. This ensures that at any point during the study, both treatment arms remain balanced across all three aetiologies. . Randomized Interventions * Control Group (50%): Standard perioperative IV antibiotics. * Vancomycin Group (50%): Standard IV antibiotics + Topical Vancomycin Powder. The same type of shunt hardware will be used for all patients in both groups to eliminate manufacturing variability as a confounder.
