Merocel sponge

Manufactured by Medtronic
Sourced in United States

The Merocel sponge is a medical device designed for various surgical and clinical applications. It is a porous, absorbent material used to control bleeding, provide wound protection, and facilitate tissue management during medical procedures. The Merocel sponge is made from polyvinyl acetal, a synthetic material that is biocompatible and can be easily shaped or cut to fit specific needs. Its core function is to provide a sterile, absorbent, and conformable material for use in medical settings.

Cytokine Profiling of Cervical Sponge Samples

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cervical sponge samples were collected from women participating in the HPV Costa Rica Vaccine Trial (CVT) using a Merocel sponge (Medtronic Xomed, Jacksonville, FL) as previously described90 . A customized panel including 32 cytokines, chemokines, and soluble receptors was quantitated using Luminex-based Milliplex Map Mulitplex Assays (Millipore, Billerica, MA) as previously described91 (link).

Nasal Obstruction in Juvenile Rats

Check if the same lab product or an alternative is used in the 5 most similar protocols
The study protocol was approved by the Ethical Committee of Jeonbuk National University (CBNU 2019–092). In the experiment, an 8-week-old SD rat was used as a juvenile rat model.11 (link) The animals were randomly assigned to two groups: without nasal obstruction (Control; n = 12), with nasal obstruction (NO; n = 12). To induce nasal obstruction, a method of packing the left nasal cavity of rats with a Merocel sponge (Medtronic Xomed, Jacksonville, FL, USA) was used. All surgical procedures were performed under general anesthesia induced by Zoletil 50 (Virbac Laboratories, Carros, France) and Rompun (Bayer Korea Ltd., Seoul, Korea). First, the Merocel sponge was cut into a length of 1.5 cm and a diameter of 1 mm to facilitate the entry into the nasal cavity of rats. Next, after wiping the left nostril of the rat with an alcohol swab, the Merocel sponge was gently inserted into the nasal cavity. Amikacin (Samu Median Co., Chungnam, Korea) was injected into the nasal cavity to allow sponge expansion and prevent infection. After induction of nasal obstruction, body weight was measured once a week for 6 weeks to examine body changes.

PRK Procedure Using WaveLight EX-500

Check if the same lab product or an alternative is used in the 5 most similar protocols
WaveLight EX-500 (WaveLight®; Alcon Laboratories, Fort Worth, TX, USA) was the device utilized for accomplishing the PRK procedure. Refractive correction in both groups was based on Wellington nomogram to achieve postoperative emmetropia in all included eyes. After sterilizing the periocular skin and eyelashes with povidone-iodine solution 10%, a drop of a preservative free local anaesthetic was instilled, and a lid speculum was inserted. A wet sponge (Merocel sponge, Medtronic Inc., Minneapolis, MN, USA) was applied to smoothly wet and cool the cornea followed by uniform drying with a dry sponge and the patient was asked to look straight-ahead at a green fixation intermittent light throughout the whole procedure.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
