Ensuring proper sterilization of surgical instruments is a critical safety measure in the Operation Theatre (OT) because it prevents surgical site infections (SSIs) caused by microbial contamination. Sterilized instruments eliminate all forms of microbial life, reducing the risk of postoperative complications and promoting patient safety. Maintaining strict sterilization protocols is essential to uphold aseptic technique and ensure successful surgical outcomes. Any lapse in sterilization can lead to severe infections, delayed healing, or even life-threatening conditions.
