6.6 Implants, Explants, Radiation & Hazardous Materials

Implants, Explants, Radiation & Hazardous Materials

Core principle: A device or hazard is safe only when the team can identify it, verify it, control exposure, and reconstruct what occurred. Traceability and chain of custody are clinical safety tools, not merely supply tasks.

Implant Readiness and Verification

Before the patient enters the operating room, confirm that the correct implant system, sizes, compatible components, instruments, backups, and manufacturer instructions are available. Loaner sets are considered contaminated on receipt and undergo the receiving facility’s complete decontamination and sterilization process. The facility establishes a delivery lead time long enough for inventory, disassembly, cleaning, inspection, packaging, sterilization, monitoring, cooling, and documentation; national standards do not create a universal 24- or 48-hour delivery mandate.

Immediately before opening an implant, match it to the order, procedure, laterality, patient anatomy, and surgeon confirmation. Inspect packaging, seal integrity, sterilization indicator, expiration date, and evidence of moisture or damage. Confirm compatibility among components; devices from different systems are not mixed unless the manufacturers expressly support the combination. If any identifier or package is questionable, quarantine it and obtain a verified replacement.

Record the implant’s name, manufacturer, model, size, lot or batch number, serial number when present, expiration date, anatomic location, and quantity. Place the implant sticker in the record only after matching it against the package; the sticker is not a substitute for visual and verbal verification. Document waste or non-implantation of an opened product. Follow applicable patient implant-information requirements and ensure the handoff includes restrictions, device-specific precautions, and follow-up needs.

Implant Sterility and Biological Monitoring

Sterilized implant loads receive the monitoring required by the device instructions, sterilizer instructions, facility policy, and applicable processing standards. Implant release is ordinarily held until the biological indicator result is available. Emergency release should be exceptional, authorized, justified, and fully documented with traceability and follow-up. Convenience, inventory shortage, or poor scheduling is not an emergency. Immediate-use steam sterilization is not a routine solution for insufficient implant inventory.

Explants and Foreign Bodies

An explanted device may be a pathology specimen, a potential source for culture, evidence in a device investigation, a manufacturer return, or property requested by the patient. Before cleaning, alteration, or release, clarify the surgeon’s order and facility pathway. Preserve attached tissue when pathology examination is required. If device failure may have caused serious injury, retain the device and accessories in their post-event state, quarantine them, document identifiers, and coordinate risk management and mandatory reporting. Maintain a signed chain of custody whenever possession changes.

A patient request for an explant does not override biohazard, pathology, legal-hold, or manufacturer-investigation requirements. Release occurs only under approved policy after required examinations, decontamination decisions, documentation, and acknowledgment of hazards. Never place an unidentified explant in a personal belongings bag.

Ionizing Radiation: ALARA

ALARA means keeping exposure as low as reasonably achievable. Minimize beam-on time, maximize distance from the source, and use shielding. Wear correctly fitted lead apron and thyroid protection when indicated, position mobile shields, and use assigned dosimeters at the location specified by the radiation-safety program. Staff do not share badges. Restrict room access, announce imaging, and keep hands out of the primary beam. For a C-arm, the x-ray tube side generally produces more scatter than the image-receptor side; maximize distance and stand on the lower-scatter side when clinical duties permit.

Pregnancy disclosure is voluntary and handled confidentially through the radiation-safety program. A declared pregnancy triggers occupational dose review and reasonable work controls; it is not an automatic reason to remove a competent employee from all imaging cases. Document equipment checks and follow policies for credentialing operators and wearing eye or extremity protection when exposure warrants it.

Hazard Communication and Exposure Response

Hazardous materials in the ASC may include formaldehyde, glutaraldehyde or other high-level disinfectants, cleaning concentrates, waste anesthetic gases, cytotoxic agents, compressed gases, and battery or laser-plume contaminants. Labels remain intact, safety data sheets are accessible, and staff know ventilation, PPE, storage incompatibilities, and spill procedures. Secondary containers are labeled; chemicals are never stored in beverage containers.

For a splash or inhalation exposure, stop work, remove the person from exposure, use the eyewash or safety shower for the product-specified duration, remove contaminated clothing, and obtain medical evaluation. Report and document the exposure promptly. Use the designated spill kit only when trained and when the spill is within the facility’s response capability; otherwise isolate the area and activate external hazardous-material support. Segregate sharps, red-bag waste, pharmaceuticals, hazardous chemicals, and regulated device waste according to law and facility contracts.
