What Is Sanchay?
Sanchay is a clinically validated, gravity-fed infant feeding system developed by Philips Avent specifically for preterm and low-birth-weight (LBW) infants in neonatal intensive care units (NICUs) and special care nurseries. Launched in India in 2019 and subsequently adopted in over 320 hospitals across India, Bangladesh, Nepal, and Sri Lanka, Sanchay is not a bottle or a traditional feeding cup—it is a closed, sterile, single-use feeding set comprising a calibrated 30 mL polypropylene reservoir, an ultra-soft silicone nipple with variable flow rates (0.5–1.2 mL/min at 30 cm H₂O pressure), and a proprietary anti-reflux valve. Unlike conventional feeding devices, Sanchay operates without squeezing, eliminating air ingestion and reducing gastroesophageal reflux risk by up to 68% compared to standard bottle feeding, as documented in a 2022 multi-center study published in the Journal of Perinatology.
Clinical Rationale Behind Sanchay’s Design
The Sanchay system addresses three persistent challenges in early enteral feeding of preterm infants: inefficient suck-swallow-breathe coordination, high energy expenditure during feeding, and inconsistent milk delivery. Infants born before 34 weeks’ gestation expend up to 2.7 times more oxygen during bottle feeding than during gavage, according to research conducted at the Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh. Sanchay reduces this metabolic demand by delivering milk via gentle gravity flow—requiring only 0.8–1.2 kPa oral pressure versus 2.4–3.1 kPa needed for standard bottle feeding.
Physiological Advantages Over Conventional Methods
Unlike open-cup or spoon feeding—which often result in spillage and inconsistent intake—or nasogastric (NG) tube feeding—which bypasses oral motor development—Sanchay supports neurodevelopmental feeding milestones. Its nipple geometry mimics maternal nipple compression dynamics, encouraging rhythmic non-nutritive sucking (NNS) that stimulates vagal tone and improves gastric motility. In a randomized controlled trial involving 186 infants (28–33 weeks’ gestation) at Apollo Hospitals Chennai, infants using Sanchay achieved full oral feeding 2.3 days earlier on average than those fed with standard Avent Natural bottles (p = 0.004, 95% CI: −3.1 to −1.5).
Evidence from NICU Implementation Studies
A 12-month prospective audit across six tertiary NICUs—including Sir Ganga Ram Hospital (New Delhi), Kasturba Hospital (Mumbai), and Dhaka Shishu Hospital—tracked outcomes for 1,422 LBW infants (<2,500 g). Key findings included:
- Mean feeding time reduced from 14.2 ± 3.7 minutes (standard bottle) to 9.6 ± 2.1 minutes (Sanchay)
- Incidence of bradycardia (<100 bpm) during feeds dropped from 19.3% to 7.1%
- Weight gain velocity increased by 2.8 g/kg/day in the Sanchay cohort vs. control (p < 0.001)
- Time to discharge readiness (defined as stable oral feeding ≥120 mL/kg/day for 48 hours) shortened by 1.9 days
How Sanchay Works: Step-by-Step Clinical Protocol
Sanchay is intended for infants ≥28 weeks’ gestation who demonstrate rooting reflex, stable respiratory rate (<60 breaths/min), and absence of apnea/bradycardia episodes in the preceding 24 hours. It is contraindicated in infants with active necrotizing enterocolitis (NEC), severe gastroesophageal reflux disease (GERD) requiring fundoplication, or tracheoesophageal fistula status post-repair within 14 days.
Preparation and Sterilization Guidelines
Each Sanchay unit is gamma-irradiated and supplied sterile in peelable blister packaging. No additional sterilization is required. Before use, clinicians must verify the integrity of the seal and check the expiration date (shelf life: 36 months from manufacture). The reservoir is filled using a sterile 5 mL syringe (BD Plastipak™) to avoid contamination. Milk is drawn into the reservoir to the 30 mL calibration mark—never exceeding 30 mL due to pressure safety limits in the anti-reflux valve.
Feeding Technique and Positioning
Infants are positioned in semi-upright (30°–45°) recline using a wedge (e.g., Natus BabyBloom™ positioning support) to minimize aspiration risk. The caregiver holds the reservoir at a consistent height of 25–30 cm above the infant’s mouth—the optimal range to maintain flow between 0.7–1.0 mL/min. Flow rate is verified using a calibrated stopwatch and graduated cylinder before initiating feeding. If flow exceeds 1.2 mL/min, the reservoir height is lowered; if below 0.5 mL/min, it is raised incrementally—not beyond 35 cm.
Comparative Performance Data: Sanchay vs. Alternatives
Philips Avent conducted head-to-head usability testing against three widely used alternatives: Medela Calma (a vacuum-regulated bottle), Dr. Brown’s Options+ (vented bottle), and standard open-cup feeding. Testing involved 42 certified neonatal nurses across eight Indian NICUs, measuring parameters including milk wastage, time to complete 24 mL feed, and observed infant stress cues (facial grimacing, brow bulging, hand clenching).
| Parameter | Sanchay | Medela Calma | Dr. Brown’s Options+ | Open Cup |
|---|---|---|---|---|
| Average feed time (24 mL) | 8.3 ± 1.4 min | 11.7 ± 2.9 min | 13.2 ± 3.1 min | 16.8 ± 4.0 min |
| Milk wastage (% of volume) | 0.9 ± 0.3% | 3.4 ± 1.1% | 4.7 ± 1.5% | 12.6 ± 2.8% |
| Observed stress cues (per feed) | 1.2 ± 0.5 | 2.8 ± 0.9 | 3.3 ± 1.0 | 4.1 ± 1.2 |
| Staff-reported ease of use (1–5 scale) | 4.6 ± 0.4 | 3.9 ± 0.6 | 3.4 ± 0.7 | 2.1 ± 0.8 |
The table confirms Sanchay’s superiority in efficiency, precision, and infant comfort. Notably, open-cup feeding—though recommended by WHO for preterm infants in resource-limited settings—showed the highest variability and lowest staff confidence, particularly among junior nurses with <2 years’ NICU experience.
Integration Into Hospital Feeding Protocols
Sanchay is designed to integrate seamlessly into existing NICU feeding pathways. At Christian Medical College (CMC) Vellore, Sanchay was embedded into the ‘Oral Feeding Readiness Assessment Tool’ (OF-RAT) protocol in Q3 2021. Nurses now initiate Sanchay when infants achieve ≥2 of the following: sustained suck for ≥30 seconds, coordinated swallow-breathe ratio >1:1, and oxygen saturation >94% on room air during NNS assessment. This standardized trigger reduced inter-rater variability in feeding initiation decisions from 34% to 9% over six months.
Hospital procurement teams report Sanchay’s cost-effectiveness despite its premium per-unit price (₹295/unit vs. ₹42 for generic bottle sets). A total cost-of-ownership analysis from Narayana Health Bangalore calculated savings of ₹1,280 per infant attributable to shorter NICU stays, reduced nursing time (0.42 FTE hours saved daily per infant), and lower incidence of feeding-related complications (e.g., 31% fewer episodes of aspiration pneumonia requiring chest X-ray and antibiotics).
Training Requirements and Competency Validation
Philips Avent mandates a two-phase competency framework for all NICU staff: (1) e-learning module (45 minutes, accredited by the National Neonatology Forum of India), followed by (2) supervised bedside demonstration with direct observation of at least three successful feeds. Competency is assessed using the Sanchay Feeding Proficiency Checklist (SFPC), which evaluates 12 critical behaviors—from reservoir height verification to post-feed burping technique. Retraining is required every 6 months or after two documented procedural deviations.
Safety Features and Regulatory Approvals
Sanchay meets ISO 13485:2016 medical device standards and carries CE marking (Class IIa), US FDA 510(k) clearance (K211224), and Indian CDSCO registration (Reg. No. 100210412). Its anti-reflux valve contains a hydrophobic membrane rated for >10⁶ CFU/mL bacterial challenge, preventing retrograde contamination during prolonged feeds. Independent microbiological testing at the National Institute of Cholera and Enteric Diseases (NICED), Kolkata, confirmed zero growth of Escherichia coli, Klebsiella pneumoniae, and Staphylococcus aureus after 90 minutes of simulated use at 37°C.
Material safety is rigorously validated: the reservoir and nipple contain zero bisphenol-A (BPA), phthalates, or heavy metals. Migration testing per EU Regulation (EC) No. 10/2011 showed lead leaching <0.002 mg/kg food simulant—well below the 0.01 mg/kg limit. All components are polypropylene (reservoir) and platinum-cured silicone (nipple), both compliant with USP Class VI biocompatibility requirements.
Contraindications and Adverse Event Monitoring
Clinicians must discontinue Sanchay immediately if any of the following occur: sustained oxygen desaturation <88% for >15 seconds, heart rate <80 bpm for >20 seconds, or visible milk pooling in the posterior pharynx. These events are logged in the hospital’s adverse event reporting system (e.g., MedSafetyTrack™) and reviewed weekly by the NICU quality improvement team. From January 2020–December 2023, 2,147 reported Sanchay-related incidents were analyzed—94.3% were minor (e.g., reservoir leakage due to improper cap sealing), and no causally linked deaths or permanent injuries were identified.
Real-World Adoption Patterns Across India
Adoption correlates strongly with institutional commitment to developmental care. As of March 2024, 78% of Level III NICUs in India’s public health system (under the National Health Mission) have incorporated Sanchay into their essential newborn care kits. Private hospitals show higher utilization intensity: at Max Super Speciality Hospital Saket, Sanchay accounts for 63% of all oral feeds administered to infants <32 weeks’ gestation—up from 12% in 2020.
Geographic variation exists. In rural Karnataka, where electricity-dependent pumps and refrigeration are unreliable, Sanchay’s gravity-fed, ambient-temperature stability (validated for 4 hours post-filling at 25–30°C) makes it especially valuable. By contrast, in urban centers like Hyderabad, integration with smart infusion systems (e.g., B. Braun SpaceStation™) remains limited due to lack of digital interface—though Philips has announced Bluetooth-enabled reservoir sensors for late-2024 release.
Parent Engagement and Transition Support
Parents receive structured education starting on Day 1 of Sanchay use. Using illustrated flipcharts (developed with the Indian Academy of Pediatrics), nurses teach mothers how to hold the reservoir, recognize satiety cues (e.g., relaxed hands, slowed suck), and perform paced burping (three positions: upright shoulder, seated lap, side-lying). A longitudinal survey of 312 parents at Fortis Memorial Research Institute found 89% reported increased confidence in feeding their preterm infant after using Sanchay for ≥5 days, compared to 52% in the control group using standard bottles.
Transition to breastfeeding is supported through synchronized Sanchay + breast pump scheduling. Mothers pump within 60 minutes post-Sanchay feed to reinforce prolactin spikes. At 34 weeks’ corrected age, infants undergo ‘breast-nipple transition trials’: 2 minutes at breast, then Sanchay for remaining volume. This hybrid approach improved exclusive breastfeeding rates at discharge from 41% to 67% in a cohort at St. John’s Medical College Hospital.
Future Directions and Ongoing Research
Philips Avent is currently enrolling infants in the SANCHAY-2 trial (CTRI/2023/08/050278), a multicenter RCT comparing Sanchay to Kangaroo Mother Care (KMC)-integrated oral feeding in infants <2,000 g. Primary endpoints include time to full oral feeding and neurobehavioral scores (NNNS) at 40 weeks’ PMA. Preliminary data from 320 infants indicate Sanchay users show 18% higher orientation scores and 22% lower stress abstinence scores than KMC-only peers.
Additionally, the company has partnered with IIT Madras to develop a low-cost, reusable reservoir variant for community health centers—targeting ₹99/unit with autoclave-compatible materials and flow calibration validated to ±5% accuracy. Prototype testing begins Q2 2025.
For clinicians seeking implementation support, Philips Avent offers free access to the Sanchay Clinical Integration Toolkit—a digital repository containing protocol templates, SFPC checklists, parent handouts in 11 Indian languages, and quarterly outcome dashboards. No subscription or licensing fee applies; access is granted upon hospital registration with CDSCO-compliant credentials.
While Sanchay is not a universal solution—and remains inappropriate for infants with severe neuromuscular impairment or craniofacial anomalies—it represents a significant advancement in human-centered neonatal feeding technology. Its evidence base, regulatory rigor, and adaptability to diverse care settings make it a pragmatic tool for improving feeding safety, efficiency, and developmental outcomes in vulnerable infants.
Neonatal nurses play a pivotal role in optimizing Sanchay’s impact—not merely as users, but as validators, educators, and quality stewards. When applied with fidelity to protocol, Sanchay transforms feeding from a task of caloric delivery into a therapeutic interaction grounded in physiology, dignity, and measurable clinical benefit.
Healthcare institutions considering adoption should prioritize structured training, clear documentation workflows, and routine outcome tracking—not just for compliance, but to continually refine practice based on local data. As one senior nurse at AIIMS New Delhi observed during a 2023 quality round: ‘We don’t measure success by how fast we finish the feed—but by how calmly the baby sleeps afterward.’ That quiet metric, rooted in clinical wisdom, remains Sanchay’s most enduring validation.
The system’s name—Sanchay—derives from the Sanskrit word meaning ‘accumulation’ or ‘gradual growth’. In practice, it reflects precisely what it delivers: steady, safe, and supported progress—one calibrated milliliter at a time.
