Pilot Study of Throat Packs Soaked in Gengigel Spray in Patients Undergoing Elective Surgery
A Early Phase 1 study testing Gengigel in people with Throat, Sore, run by University of Malaya at 1 site in Malaysia.
Trial summary
Throat packs are commonly used in many surgical procedures involving the oral cavity and pharynx, primarily to prevent blood, saliva, and other debris from entering the lower respiratory tract, thereby maintaining a clear airway and reducing the risk of aspiration and respiratory complications.

About this study
Official title: The Pilot Study of Throat Packs Soaked in Gengigel Spray in Patients Undergoing Elective Surgery Under General Anaesthesia
Throat packs are commonly used in many surgical procedures involving the oral cavity and pharynx, primarily to prevent blood, saliva, and other debris from entering the lower respiratory tract, thereby maintaining a clear airway and reducing the risk of aspiration and respiratory complications. Traditionally, these packs are moistened with saline or used in a dry state, with the choice often depending on the surgeon's preference and specific surgical requirements. However, despite their widespread usage, the exploration of alternative substances to moisten throat packs, particularly those with additional therapeutic benefits, remains limited in medical research. This pilot study introduces Gengigel spray as an innovative alternative to saline for moistening throat packs. Gengigel, a hyaluronic acid (HA)-based product, is known for its healing properties and anti-inflammatory effects, which are beneficial in oral care. Gengigel provides a non-anesthetic approach that promotes tissue repair and reduces inflammation. This makes it particularly advantageous in the context of surgical procedures where reducing postoperative inflammation and promoting mucosal healing are crucial.
Read the detailed description
Using throat packs is a standard practice in surgeries involving the oral cavity, pharynx, and upper airway to prevent the aspiration of blood and other debris, which could lead to postoperative complications such as aspiration pneumonia. Traditionally, these throat packs are moistened with saline or left dry. However, this conventional approach has been associated with postoperative throat pain and discomfort, which are common and often distressing complications for patients undergoing surgery under general anesthesia. The discomfort caused by these packs can delay recovery, extend hospital stays, and negatively impact overall patient satisfaction with the surgical experience.
Gengigel presents a novel alternative with distinct advantages. Gengigel, which contains hyaluronic acid (HA), is recognized for its anti-inflammatory and healing properties, making it a promising candidate for improving postoperative outcomes when used in throat packs. Despite Gengigel's established use in other medical applications, such as wound care and oral health, there is currently no research exploring its effectiveness in moistening throat packs during surgical procedures. This represents a significant knowledge gap, as the combination of Gengigel's healing and anti-inflammatory effects could potentially address both pain and mucosal recovery.
Addressing this gap is crucial for advancing postoperative care, as current literature does not adequately explore the potential benefits or risks associated with using Gengigel in throat packs. Furthermore, there is a lack of data on patient outcomes, including the extent of pain relief, the speed of mucosal healing, potential complications, and overall patient satisfaction when Gengigel is utilized in this context. The absence of such data limits the ability of healthcare providers to make evidence-based decisions that could improve patient care.
To bridge this gap, this study proposes a randomized controlled trial (RCT) to compare the outcomes of using Gengigel-soaked throat packs versus traditional saline-soaked packs in patients undergoing surgery under general anesthesia. The study will systematically assess postoperative throat pain levels, evaluate the degree of mucosal healing, monitor for any adverse effects, and measure overall patient satisfaction. By conducting this comprehensive evaluation, the research aims to provide robust evidence that could guide the use of Gengigel in throat packs, potentially setting a new standard in postoperative care. Ultimately, the findings could lead to enhanced patient comfort, faster recovery times, and a higher quality of care for patients undergoing surgeries involving the oral cavity and pharynx.
