Chapter 1: Hemostasis Fundamentals and the Role of Absorbable Gelatin Sponge (AGS)

1.1 Physiology of Hemostasis (Simplified View)

Hemostasis is the body’s natural process to stop bleeding. In surgery or trauma, bleeding may be from:

• Capillaries – slow, diffuse oozing
• Veins – steady dark-red bleeding
• Arteries – pulsatile, bright-red bleeding

Conventional techniques (ligature, cautery, compression) are often effective, but in oozing surfaces, fragile tissues, or inaccessible sites, surgeons require topical hemostats like gelatin sponge.

1.2 Mechanism of Action of Gelatin Sponge Hemostats

Unlike pharmacological agents, gelatin sponges act through physical and local mechanisms:

Physical Scaffold Effect

The porous sponge structure provides a three-dimensional matrix where platelets and blood components can stick. This enhances formation of a stable clot at the bleeding surface.

Fluid Absorption & Concentration of Clotting Factors

Gelatin can absorb up to 40–50 times its own weight in blood. The sponge swells rapidly, concentrating clotting proteins and cells at the site. This accelerates the body’s natural hemostatic response.

Mechanical Tamponade

When pressed gently on the bleeding site, the swollen sponge exerts mild mechanical pressure, sealing small vessels.

Biodegradation & Healing Support

Gelatin sponges are completely absorbed by enzymatic action within 2–6 weeks (depending on size, density, and implantation site). During resorption, they are replaced by granulation tissue—supporting natural wound healing.

1.3 Clinical Indications and Contraindications

Indications (Common Use Cases)

• Adjunctive control of bleeding when ligature, suturing, or cautery are impractical or ineffective.
• Effective in capillary and venous bleeding (especially diffuse oozing).
• Commonly used in: General surgery (liver, spleen, kidney), ENT (tonsillectomy, nasal surgery), Neurosurgery (dural closure, spinal surgery), Dental extraction sockets, Gynecological procedures.

Contraindications & Warnings

• ❌ Intravascular use – may cause embolism.
• ❌ Hypersensitivity to gelatin – rare but possible.
• ❌ Infected/contaminated wounds – gelatin can act as a bacterial growth medium.
• ⚠️ Compressive risk – avoid use near nerves or confined cavities (due to swelling).
• ⚠️ Excess removal – once bleeding stops, remove excess sponge to avoid foreign-body reactions.

1.4 Key Advantages of Gelatin Sponge Hemostats

• Versatile – can be cut to size, applied dry or moistened.
• Safe – non-toxic, biocompatible, and absorbable.
• Convenient – ready-to-use and adaptable to irregular wound surfaces.
• Effective in Oozing Surfaces – where traditional suturing or cautery is difficult.

1.5 Limitations Compared to Other Hemostats

• Slower action than advanced agents (e.g., fibrin sealants, thrombin-based products).
• Not suitable for major arterial bleeding.
• Swelling risk in confined anatomical spaces.
• Potential for delayed wound healing if not removed after hemostasis.

Purpose: detect particulates, visible contamination, discoloration, foreign particles, tears, or dust. Equipment: white background inspection light box (ISO Class recommendations if sterile), magnifier (×4).

Procedure: Inspect each sample under uniform bright light against white background. Note color (off-white/pale yellow typical), uniformity, visible particles, surface finish, signs of compression damage. For particulate check, press sponge and inspect for loose particles on surface and inside pores.

Acceptance: No visible foreign particulate; color and surface consistent with reference standard.

Purpose: ensure product within specified size tolerance and consistent density. Equipment: digital caliper (0.01 mm), precision balance (0.001 g), ruler, volumetric method for irregular shapes.

Procedure — dimensions: Measure length, width, and thickness at three points and report mean ± SD. Tolerance example: ±2 mm for length/width, ±1 mm for thickness (validate per product).

Procedure — density: Weigh dry sponge (W_dry, g). Measure volume (V): for regular rectangular: L×W×T (cm³). For irregular: liquid displacement in non-wetting fluid / geometry. Density = W_dry / V (g/cm³). Acceptance (example): Density 0.05–0.25 g/cm³ (product dependent) and dimensional tolerance within stated spec.

Purpose: ensure moisture content within limits to avoid microbial growth and ensure shelf stability. Equipment: oven (105 ± 2 °C) or moisture analyzer, desiccator, analytical balance (0.1 mg). Use method per USP if available.

Procedure (oven): Weigh sample (W1). Place in pre-weighed dish. Dry at 105 °C for 4 hours (or until constant weight). Cool in desiccator; weigh (W2). LOD (%) = [(W1 − W2) / W1] × 100. Acceptance (example): ≤ 10–15% (define for your product). Validate drying time & temp during method validation.

6.1.5 Absorption Capacity & Absorption Time

Purpose: quantify how much fluid the sponge can absorb and how quickly — core functional attribute. Equipment: analytical balance, graduated cylinder, timer, simulated physiological fluid (0.9% NaCl) or water at 37 °C.

Procedure — capacity: Condition sponge; weigh dry (Wd). Immerse sponge in 37 °C saline for a fixed time (e.g., 30 s or until saturated) — standardize immersion method (gentle submersion without squeezing). Allow drip for 5–10 s on mesh to remove free surface liquid. Weigh wet (Ww). Absorption capacity (g/g) = (Ww − Wd) / Wd.

Procedure — absorption time: time required from first contact until no visible free liquid on surface or until a pre-defined uptake mass achieved. Use stopwatch. Acceptance (example): Capacity ≥ 20 g water/g sponge; Absorption time ≤ 30 s. (Tune per formulation.)

Procedure — compression: For compression modulus: compress sample at constant crosshead speed (e.g., 5 mm/min) until specified strain (e.g., 50% deformation). Record peak force and % rebound after release. For tensile: if sponge form permits, perform tensile test to failure; report tensile strength and elongation.

Friability (if required): tumble a defined number units and evaluate weight loss and structural breakdown. Acceptance (example): Compression force to 50% strain X–Y N (set during development); %recovery ≥ 30% after 1 min. Friability ≤ 5% weight loss. (Establish during validation.)

Purpose: characterize pore architecture influencing fluid uptake & cell infiltration. Equipment: stereomicroscope / SEM (for high resolution), digital camera, image analysis software (ImageJ).

Procedure: Image multiple representative fields (e.g., 5–10 fields) at known magnification. Use ImageJ: set scale, threshold, analyze particles to obtain mean pore area/diameter, pore count, and porosity percentage. Report mean pore diameter, SD, and distribution (e.g., % pores <100 µm, 100–300 µm, >300 µm). Acceptance (example): Mean pore size 100–400 µm with >70% pores in target range (product dependent).

6.1.9 FTIR for Material Identity

Purpose: confirm polymer identity (gelatin) and check for unexpected chemical modifications or residues. Equipment: FTIR spectrometer with ATR accessory.

Procedure: Place small piece of sponge on ATR crystal; collect spectrum (4000–400 cm⁻¹). Compare characteristic gelatin peaks (amide I ~1650 cm⁻¹, amide II ~1550 cm⁻¹, amide III ~1240 cm⁻¹).
