Hemostasis and retained surgical items
Research Guide
What is Hemostasis and retained surgical items?
Hemostasis and retained surgical items refers to advances in hemostatic agents and techniques, such as topical hemostatic dressings, fibrin sealants, and chitosan-based materials, for controlling bleeding in surgical and trauma settings, alongside research on items unintentionally left inside patients after surgery.
This field encompasses 18,104 papers on hemostatic agents, surgical hemostasis, topical dressings, and bleeding control in surgical and trauma contexts. Key areas include fibrin sealants, chitosan-based dressings, combat operations applications, wound healing, and integration into the surgical toolbox. Research evaluates materials like hemostatic sponges and their roles in procedures prone to retained items.
Topic Hierarchy
Research Sub-Topics
Topical Hemostatic Dressings
Researchers investigate biocompatible materials such as oxidized regenerated cellulose and gelatin-based sponges for intraoperative bleeding control. Studies evaluate efficacy, absorption rates, and adhesion properties in various surgical contexts.
Fibrin Sealants
This area examines synthetic and autologous fibrin glues for hemostasis and tissue sealing in cardiovascular and orthopedic surgeries. Research focuses on polymerization mechanisms, sealant durability, and complication rates like embolization.
Chitosan-Based Hemostatic Dressings
Studies explore chitosan's mucoadhesive and platelet-activating properties for prehospital trauma care and combat casualty management. Researchers assess antibacterial effects, biodegradability, and performance in coagulopathic conditions.
Platelet-Rich Fibrin in Wound Healing
Investigations cover PRF matrices derived from autologous blood for promoting angiogenesis and tissue regeneration post-surgery. Research analyzes growth factor release profiles and clinical outcomes in chronic wounds.
Hemostatic Agents in Combat Operations
This sub-topic evaluates field-deployable agents like QuikClot in junctional and non-compressible hemorrhage during military engagements. Studies compare survival rates, application times, and long-term tissue effects from real-world data.
Why It Matters
Hemostatic agents enable rapid bleeding control in trauma and surgery, reducing mortality from hemorrhage, as seen in damage control surgery for penetrating abdominal injuries where physiologic derangements like dilutional coagulopathy preclude definitive procedures; Rotondo et al. (1993) in "‘DAMAGE CONTROL'" described abbreviated laparotomy followed by resuscitation to address such challenges. Platelet-rich fibrin (PRF) and platelet-rich plasma (PRP) provide autologous proteins for tissue regeneration and wound healing, with Eppley et al. (2004) in "Platelet Quantification and Growth Factor Analysis from Platelet-Rich Plasma: Implications for Wound Healing" quantifying growth factors that modulate healing cascades. Injectable cryogels offer solutions for noncompressible hemorrhage, absorbing blood and promoting recovery, per Zhao et al. (2018) in "Injectable antibacterial conductive nanocomposite cryogels with rapid shape recovery for noncompressible hemorrhage and wound healing," which reported rapid shape recovery properties. Retained surgical items, though less detailed in top papers, link to hemostasis via procedural risks during bleeding management, impacting surgical safety across 18,104 studies.
Reading Guide
Where to Start
"Definition of major bleeding in clinical investigations of antihemostatic medicinal products in surgical patients" by Schulman et al. (2009), as it provides foundational criteria for evaluating bleeding in hemostasis studies, essential for understanding clinical trial standards.
Key Papers Explained
Schulman et al. (2009) in "Definition of major bleeding in clinical investigations of antihemostatic medicinal products in surgical patients" establishes bleeding assessment standards, which Rotondo et al. (1993) in "‘DAMAGE CONTROL'" applies to trauma surgery contexts with coagulopathy. Dohan et al. (2006) in "Platelet-rich fibrin (PRF): A second-generation platelet concentrate. Part I: Technological concepts and evolution" and Anitua et al. (2003) in "Autologous platelets as a source of proteins for healing and tissue regeneration" build on this by detailing platelet-based agents for hemostasis and regeneration. Zhao et al. (2018) in "Injectable antibacterial conductive nanocomposite cryogels with rapid shape recovery for noncompressible hemorrhage and wound healing" and Eppley et al. (2004) in "Platelet Quantification and Growth Factor Analysis from Platelet-Rich Plasma: Implications for Wound Healing" extend to advanced materials and quantified growth factors, connecting early definitions to modern applications.

Advanced Directions
Current research emphasizes shape-memory materials like cryogels for irregular wounds and platelet concentrates for regeneration, as in top-cited works, with no recent preprints shifting focus. Frontiers involve integrating hemostatics into damage control protocols to address retained item risks during rapid procedures.

Frequently Asked Questions
What defines major bleeding in antihemostatic drug trials for surgical patients?
Major bleeding is defined in clinical investigations of antihemostatic medicinal products in surgical patients through specific criteria outlined by Schulman et al. (2009) in "Definition of major bleeding in clinical investigations of antihemostatic medicinal products in surgical patients." This standardization aids consistent evaluation of bleeding risks in hemostasis research.
How does platelet-rich fibrin (PRF) function in hemostasis and tissue regeneration?
Platelet-rich fibrin (PRF) is a second-generation platelet concentrate that evolves technological concepts for releasing growth factors promoting tissue repair. Dohan et al. (2006) in "Platelet-rich fibrin (PRF): A second-generation platelet concentrate. Part I: Technological concepts and evolution" detailed its role in haemostasis and regeneration beyond clot formation.
What is damage control surgery in trauma with bleeding?
Damage control surgery involves abbreviated laparotomy for penetrating injuries with vascular and visceral damage, prioritizing resuscitation over definitive repair amid coagulopathy, hypothermia, and acidosis. Rotondo et al. (1993) in "‘DAMAGE CONTROL'" defined this approach to improve survival in severe trauma.
How do autologous platelets contribute to wound healing?
Autologous platelets release proteins that initiate haemostasis and promote tissue regeneration by adhering, aggregating, and forming procoagulant surfaces for thrombin and fibrin generation. Anitua et al. (2003) in "Autologous platelets as a source of proteins for healing and tissue regeneration" summarized their dual role in clotting and repair.
What are applications of injectable cryogels in hemostasis?
Injectable antibacterial conductive nanocomposite cryogels based on carbon nanotubes and gelatin provide high blood absorption, fast recovery, and shape memory for noncompressible hemorrhage control and wound healing. Zhao et al. (2018) in "Injectable antibacterial conductive nanocomposite cryogels with rapid shape recovery for noncompressible hemorrhage and wound healing" demonstrated their efficacy in irregular wounds.
What growth factors are in platelet-rich plasma for wound healing?
Platelet-rich plasma contains concentrated growth factors from activated platelets that initiate and modulate wound healing in soft and hard tissues. Eppley et al. (2004) in "Platelet Quantification and Growth Factor Analysis from Platelet-Rich Plasma: Implications for Wound Healing" analyzed these factors' implications.

Recent Trends
The field spans 18,104 works with sustained interest in hemostatic agents, evidenced by high citations for foundational papers like Schulman et al. (2009, 3719 citations) on bleeding definitions and Zhao et al. (2018, 1122 citations) on cryogels, but growth rate data is unavailable and no preprints or news from the last 12 months indicate steady rather than accelerating progress.
