Introduction
Under normal circumstances, the shelf life of an opened sterile pack is typically 4 hours. Before using a sterile pack, carefully verify the name of the sterile pack, the sterilization date, and whether the packaging is intact. If the sterile pack is found to be loose, damp, or if the color of the chemical indicator tape has changed, discontinue use immediately.
Generally, a sterile pack refers to a surgical pack or instrument pack that has undergone either high-temperature or low-temperature sterilization, with its contents maintained in a sterile condition. A sterile pack may be used for up to 4 hours after it is opened. Detailed explanation is as follows:
A sterile pack that has already been opened typically has an effective duration of 4 hours. This is because once the sterile pack is opened, the sterile items inside are exposed to the air and are susceptible to contamination. Therefore, the contents must be used within the specified time to ensure sterility and safety. When using an opened sterile pack, it is important to maintain clean and disinfected hands to prevent contamination of the sterile items. Additionally, correct sterile procedures should also be followed to ensure the maintenance of sterility.
Prior to using a sterile pack, carefully verify the name of the pack, the sterilization date, and whether the packaging is intact and undamaged. If the sterile pack is found to be loose, damp, or if there is a color change in the chemical indicator tape, use should be stopped immediately.
