Surgical suture procurement across Vietnamese healthcare—administered under Ministry of Health (MoH) tender regulations across central hospitals like Chợ Rẫy Hospital and Bach Mai Hospital—demands meticulous clinical evaluation. Synthetic absorbable braided sutures constitute over 60% of all operating room wound closure volumes. Within this category, two homopolymer and copolymer formulations dominate surgical preference: Polyglycolic Acid (PGA) and Polyglactin 910 (PGLA, generic equivalent to Vicryl). Sourcing directors and tender contractors must understand the precise chemical, tensile, and degradation differences between these two materials to secure winning hospital bids.
Surgical suture procurement across Vietnamese healthcare demands meticulous clinical evaluation of synthetic absorbable braided materials.
Both are synthetic braided absorbable polymers, but PGA is a pure 100% homopolymer of glycolide, whereas PGLA is a copolymer of 90% glycolide and 10% L-lactide. The lactide component in PGLA renders the material slightly more hydrophobic, extending its tensile strength retention profile by 3 to 5 days compared to PGA, while its calcium stearate coating delivers smoother knot slide.
| Performance Parameter | Polyglycolic Acid (PGA) | Polyglactin 910 (PGLA) | Clinical & Sourcing Consequence |
|---|---|---|---|
| Polymer Composition | 100% Polyglycolide | 90% Glycolide + 10% L-Lactide | PGLA lactide content slows hydrolysis rate |
| Coating Material | Polycaprolactone + Calcium Stearate | Poly(glycolide-co-lactide) + Ca Stearate | Facilitates smooth knot tie-down without sawing |
| 50% Tensile Retention | 14 – 18 days post-implantation | 21 days post-implantation | PGLA supports slow-healing fascial tissue longer |
| Complete Mass Absorption | 60 – 90 days via hydrolysis | 56 – 70 days via hydrolysis | Minimal late foreign-body tissue reaction |
| Knot Pull Strength (EP/USP) | Exceeds USP requirements by > 20% | Exceeds USP requirements by > 25% | High security in laparoscopic knot throwing |
| Typical Tender Cost Index | Baseline (Cost-effective) | 1.15x – 1.25x over PGA | PGA preferred for cost-sensitive provincial tenders |
In abdominal wall closure and gastrointestinal anastomosis, suture drag matters. A rough braided suture saws through delicate bowel wall. Sourcing precision-coated PGLA or PGA with micro-braiding ensures smooth passage and unyielding knot security.
Medical devices require a valid Medical Device Registration Number (Circulation Number) issued by the Vietnam Ministry of Health, supported by Common Submission Dossier Template (CSDT) submissions and airtight aluminum foil blister packaging.
PGA Rapid or PGLA Rapid (irradiated to accelerate absorption) loses tensile strength within 7–10 days and completely absorbs within 42 days, making it ideal for episiotomies and pediatric skin closure.

Decree 04/2025 didn't rewrite Vietnam's medical device rules from scratch, but it changed deadlines, a licensing portal, and the approval chain right as hospitals pull away from resharpened blades toward single-use. Distributors relying on last year's paperwork are the ones getting held at port.
