Global cerebral ischaemia secondary to intra-operative hypotension following the administration of protamine
AI-generated summary
A 62-year-old man died from global cerebral ischaemia following intra-operative hypotension after protamine administration during a cardiac ablation procedure. He had suffered a severe hypotensive reaction to protamine 8 days earlier during coronary artery bypass surgery, which was inadequately documented and not communicated to the ablation team. Critical failures included: incomplete anaesthetic charting of the initial protamine reaction, absent handover communication between ICU and EP laboratory staff, no completion of Surgical Safety Checklist or Time Out before the ablation, and the red alert bracelet being covered by surgical drapes. While the patient was in a perilous cardiac condition, knowledge of his previous protamine reaction might have prompted reconsideration of its necessity or administration method, potentially preventing death. The case emphasises the importance of accurate documentation and structured handover in complex critically ill patients.

Coroner's recommendations
Royal Melbourne Hospital to develop a general guideline for the use of protamine, outlining indications, high-risk patients, potential complications and management options for high risk situations
Royal Melbourne Hospital to educate anaesthetists regarding the need to document any significant intraoperative event and medications administered
Royal Melbourne Hospital to amend Surgical Safety Checklist document to include adverse drug reactions as well as known allergies
Improve handover processes for collecting patients from ICU, including notification of allergies/adverse drug reactions, structured verbal clinical handover format, and designated handover location
Ensure Surgical Safety Checklist is completed by transferring unit for all patients and included as part of handover process
Clinicians directly involved in patient care must participate in handover
Patient must not be accepted for transfer unless all relevant documentation completed and formally handed over using ISBAR minimum data set
EP laboratory nursing staff must check and sign off Surgical Safety Checklist on acceptance of patient
Provide further education to ICU and EP laboratory medical and nursing staff on importance of Surgical Safety Checklist completion and Time Out conduct
Improve documentation of protamine reactions on anaesthetic chart, specifying type, severity and treatment required
Note allergy/sensitivity on front of anaesthetic chart alert section in addition to computerised patient master index and case note alerts
Develop policy reviewing indications for protamine use in non-cardiac theatre situations, considering current clinical state and presence/type/severity of previous reactions
