Safety Norms: Cardiothoracic and Vascular Surgery

1Purpose, Scope, and Safety Principles

This document sets out safety norms for operative and peri-operative care in cardiothoracic and vascular surgery. It covers planned and urgent procedures on the heart, great vessels, lungs, esophagus, chest wall, and peripheral arteries and veins. It spans pre-operative assessment, the operation itself, recovery, and early follow-up. It applies to every person who prepares, performs, supports, monitors, or documents these procedures.

Four principles guide every norm. The patient comes first. No single person is the only safeguard. Uncertainty triggers a pause and escalation. Decisions follow documented evidence and approved local protocols. Peri-operative means the period before, during, and after surgery. A sterile field is a controlled area kept free of microorganisms. Cardiopulmonary bypass is a machine that temporarily performs heart and lung function during surgery.

• Mandatory: Use only approved procedures and current local protocols for patient care.
• Mandatory: Do not perform any task that you have not been trained and authorized to perform.
• Recommended: Review this document with the department periodically and after any significant incident.

2Roles, Competence, and Accountability

The attending surgeon holds overall responsibility for the operative plan, the conduct of the surgical team, and documentation of key decisions. Anesthesia clinicians are responsible for airway management, hemodynamic support, drug delivery, and the anesthetic record. Perfusionists operate the bypass circuit and related devices under physician direction. Operating room nurses and surgical technologists manage instruments, counts, sterile technique, and device readiness. Intensive care and step-down staff manage post-operative monitoring and the first hours of recovery.

Competence is established through credentialing, privileging, and documented supervision, not by job title. Each facility should define who may perform, assist, and supervise each procedure, and these authorizations must be verified before a case begins. Credentialing rules and licensure requirements are jurisdiction-dependent and must be confirmed with the relevant regulator or hospital governance body. Trainees work under a named supervisor, and that supervision level must be stated on the case board.

• Mandatory: No one may perform or assist with a procedure outside their documented privileges or scope of practice.
• Mandatory: Any team member may stop a procedure or raise a concern when patient safety is at risk, without fear of reprisal.
• Mandatory: Each case must have a named attending, anesthesia lead, perfusion lead when bypass is used, and circulating nurse.
• Recommended: Maintain a visible role assignment on the case board or electronic whiteboard for each operation.

3Realistic Hazards and Risk Assessment

Cardiothoracic and vascular work involves high-acuity patients with cardiac, pulmonary, vascular, renal, or neurological compromise. Typical hazards include massive bleeding, air or clot embolism, arrhythmia, myocardial ischemia, cardiac arrest, hypothermia or rewarming complications during bypass, medication error with heparin, protamine, vasoactive infusions, and electrolyte agents, pneumothorax, stroke, surgical site infection, retained instruments, device malfunction, and pressure or nerve injury from positioning. Staff face hazards too, including sharps injury, exposure to bloodborne pathogens, electrosurgical burns, radiation during fluoroscopy, heavy lifting, and prolonged standing.

Risk should be assessed before each case using a structured approach. Identify the hazard, estimate likelihood and severity, rate the risk as low, moderate, or high, and assign a control with a named owner. Recalculate the rating when the patient's condition changes, such as a new arrhythmia, falling oxygenation, unexpected anatomy, or failure of a device. The facility's approved risk framework governs the scoring method.

• High risk: uncontrolled bleeding, bypass circuit failure, air embolism, loss of airway, and cardiac arrest require pre-briefed responses and named responders.
• Moderate risk: transfusion reactions, electrolyte imbalance, arrhythmia, and count discrepancies require defined checks and documented responses.
• Patient factors to record before surgery: anticoagulant and antiplatelet use, prior sternotomy, renal function, allergies, frailty, implanted devices, and prior radiation to the chest.
• Staff factors to record: fatigue, sharps training status, and current immunization status as required by occupational health policy.

4Preventive Controls and Safe Practice

Consent must be informed, specific, and documented before any procedure. The consenting clinician explains the diagnosis, the proposed operation, material risks, reasonable alternatives, expected recovery, and the patient's right to decline. A signed form is not a substitute for conversation. Patients who lack decision-making capacity are handled under local law and surrogate decision-making rules. Consent for blood products and for procedures that may become necessary during surgery should be addressed under local policy before the operation begins.

Pre-operative verification uses a structured checklist. The team confirms patient identity with two identifiers, procedure and laterality, marked site where applicable, allergies, anticoagulant and antiplatelet status, blood availability, implant requirements, and fasting status. Before incision, the team performs a time-out and confirms these items aloud. Evidence-based protocols, such as antibiotic prophylaxis timing, blood conservation strategies, and enhanced recovery pathways, should be used. Any deviation must be documented with a clinical reason.

Scope of practice governs who makes each decision. Residents, advanced practice clinicians, and perfusionists work under the supervision level defined by the facility. A trainee may not independently change the operative plan, accept a new clinical risk, or release a device without direction from the named supervisor. When a trainee is unsure, the default action is to pause and call the supervisor.

• Mandatory: Perform a documented time-out before incision and before any major change in the procedure.
• Mandatory: Count sponges, needles, and instruments at defined points and reconcile discrepancies before closure. If counts cannot be reconciled, follow the local protocol for imaging and attending notification.
• Mandatory: Confirm bypass circuit priming, de-airing, cannula connections, and alarm settings with a second qualified person before initiating circulatory support.
• Mandatory: Use medications and doses from approved order sets, and independently double-check high-alert drugs such as heparin, protamine, insulin, potassium, and vasoactive infusions.
• Mandatory: Label all specimens and implants with patient identifiers before they leave the sterile field.
• Mandatory: Confirm implant records and device serial numbers before closure and enter them in the permanent record.
• Recommended: Use a standardized handoff tool when transferring patients between the operating room, recovery, and intensive care.
• Recommended: Apply hemostasis and blood conservation protocols, and review transfusion triggers with the attending.

5Infection Prevention, Equipment, and Environmental Controls

Surgical site infection, mediastinitis, sternal wound complications, and vascular graft infection are serious outcomes. Prevention depends on hand hygiene, skin antisepsis, prophylactic antibiotics given within the protocol window, controlled movement in the operating room, and strict sterile technique. Ventilation, temperature, humidity, and pressure requirements are set by facility design and jurisdictional standards. Confirm current versions with the relevant authority and the infection prevention team.

Equipment and environment create additional hazards. Electrosurgical units must be used with approved return electrodes and smoke evacuation. Oxygen-enriched fields require a fire-safety protocol, and staff must confirm that ignition sources are controlled before energy devices are activated. Heavy patient transfers, perfusion pump equipment, cables, and tubing create trip and entrapment risks. Manufacturer instructions govern cleaning, reprocessing, and maintenance; follow them and do not improvise.

• Mandatory: Maintain the sterile field, allow only sterile personnel to touch it, and report any breach to the attending, who decides whether the affected area requires reassessment.
• Mandatory: Wear dedicated surgical attire and masks as required by local policy, and keep personal items out of the operating room.
• Mandatory: Use only approved disinfectants, and follow manufacturer contact times.
• Mandatory: Remove damaged cables or devices from service and tag them until biomedical engineering clears them.
• Recommended: Track surgical site infection rates and review cases with the infection prevention committee.
• Recommended: Use mechanical lifting aids and documented patient transfer plans for heavy or unstable patients.

6Information, Privacy, and Security Safeguards

Cardiothoracic and vascular records contain sensitive diagnoses, imaging, genetic or family history, device data, and detailed operative findings. Access is limited to people with a treatment, operational, quality, or legal need. Handling must follow the privacy and data protection law and facility policy that applies where care is delivered. Verify current requirements with the privacy officer and the information security team.

Connected devices, pump data, and monitoring systems create security exposure. Only approved devices and software may connect to clinical networks. Passwords, badge access, and session timeouts protect shared workstations in the operating room and intensive care unit. Staff should assume that recordings, screenshots, and verbal discussions can be overheard and should keep clinical conversations appropriately discreet.

• Mandatory: Do not photograph or record patients, screens, or operative fields on personal devices.
• Mandatory: Lock workstations and log out of shared displays. Do not discuss patients in public corridors, elevators, or social media.
• Mandatory: Report suspected unauthorized access, lost devices, or ransomware symptoms immediately to the privacy and information security teams.
• Recommended: Use approved secure messaging, and confirm device pairing and software updates with biomedical engineering.

7Incident Reporting, Emergency Response, and Escalation

Every incident, near miss, and unexpected event should be reported through the facility reporting system promptly, ideally before the end of the shift. Reports should be factual and blame-free. They should describe what happened, what was done, the patient impact, and the contributing conditions. Disclosure of adverse events to patients and families follows local policy and professional duties, and the attending leads that conversation.

Emergencies require pre-briefed responses. Each team should know the location of emergency drugs, defibrillators, blood products, rapid transfusion protocols, and the process for calling a rapid response or code team. Escalation is required when a patient deteriorates, when a team member feels unsafe, when a device fails, or when the plan no longer matches the findings. Emergency medical services and the code team are contacted as local policy dictates. This guidance does not replace emergency services or the authority of trained emergency responders.

• Mandatory: Call for help early, stating the problem, location, and resources needed.
• Mandatory: Stop and reassess when any team member voices a stop-the-line concern, and document the outcome.
• Mandatory: Notify the attending and the risk management team of any retained item, wrong-site concern, unplanned return to the operating room, or unexpected death.
• Mandatory: Do not remove or alter devices, sharps, or specimens involved in an incident without local investigation instructions.
• Recommended: Hold a short team debrief after major events to capture lessons learned and preserve situational detail.

8Records, Training, Inspection, and Review

Accurate records support safety, continuity of care, and legal defensibility. Operative notes, anesthesia records, perfusion logs, implant records, count sheets, consent forms, and transfusion documentation should be completed contemporaneously. Record retention periods are jurisdiction-dependent and should be confirmed with facility records management.

Training should be role-specific and documented. It should cover procedures, emergency simulations, equipment use, infection prevention, privacy, and escalation. Equipment inspection, calibration, and maintenance follow manufacturer instructions and biomedical engineering schedules. Audit results, incidents, and outcome data should feed periodic review of these norms, with changes communicated to all staff in writing.

• Mandatory: Keep training, competency, and privilege records current and available for audit.
• Mandatory: Remove from service any staff member whose competency or health status creates a safety concern until supervisory review is complete.
• Recommended: Run team simulations of bleeding, bypass failure, and air embolism at a frequency set locally.
• Recommended: Review protocol compliance and outcomes at each departmental quality meeting, and assign action owners with due review steps.
