C1 Circulation
Establish adequacy of peripheral circulation ((rate, rhythm and character of pulse) - CPR
C2 Colour Note saturation. Pulse oximetry - Test probe on own finger

O2 Oxygen analyser
Adjust inspired oxygen concentration to 100%Check that the oxygen analyser shows a rising oxygen concentration
V1 Ventilation
Ventilate the lungs by handTo assess circuit integrity, airway patency, chest compliance and air entry by ‘‘feel’’ and auscultation. (Capnography)
V2 Vaporiser Note settings and levels of agentsGas leaks during pressurisationConsider the possibility of the wrong agent

E1 Endotracheal tube
Check the endotracheal tube (leaks or kinks or obstructions)

Review all other equipment in contact with or relevant to the patient (e.g. diathermy, humidifiers, heating blankets, endoscopes, probes, prostheses, retractors and other appliances).
A Airway Check patency of the unintubated airway(Consider laryngospasm or presence of foreign body, blood, gastric contents, nasopharyngeal or bronchial secretions)
B Breathing Assess pattern, adequacy and distribution of ventilation
C Circulation Repeat evaluation of peripheral perfusion, pulse, blood pressure, ECG and and any possible obstruction to venous return, raisedintrathoracic pressure or tamponade of the heart
D Drugs Review drug or substance administrationWrong drug, Wrong dose

MedicationAll drugs should be clearly
labelled
The label on both ampoule and syringe should be read carefully before the drug is drawn up or injected
Ideally drugs should be drawn up and labelled by the anaesthetist who administers them.

Counseling
Pre operative counseling - Possible complication - Remote complication
• Post operative counseling - The Swiss Foundation for Patient Safety has published guidelines describing the actions to take after an adverse event has occurred .

Recommendations for senior staff members
A severe medical error is an emergency
Confidence between the senior staff and the involved professional
Involved professionals need a professional and objective discussion with, as well as emotional support from, peers in their department
Seniors should offer support for the disclosing conversation with the patient and/or the relatives
A professional work-up of that case based on facts is important for analysis and learning out of medical error. Ex..
![Page 29: SAFE ANAESTHESIA PRACTICE](https://reader035.vdocuments.mx/reader035/viewer/2022070422/568163d1550346895dd51640/html5/thumbnails/29.jpg)
Recommendations for colleagues
Be aware that such an adverse event could happen to you also
Offer time to discuss the case with your colleague. Listen to what your colleague wants to tell and support him/her with your professional expertise
Address any culture of blame either directly from within the team or by any other colleagues
![Page 30: SAFE ANAESTHESIA PRACTICE](https://reader035.vdocuments.mx/reader035/viewer/2022070422/568163d1550346895dd51640/html5/thumbnails/30.jpg)
Recommendations for healthcare professionals directly involved in an adverse event
Do not suppress any feelings of emotion you may encounter after your involvement in a medical error
Talk through what has happened with a dependable colleague or senior member of staff. This is not weakness. This represents appropriate professional behaviour
Take part in a formal debriefing session. Try to draw conclusions and learn from this event. Ex..
If possible talk to your patient/their relatives and engage with them in open disclosure conversations
If you experience any uncertainties regarding the management of future cases seek support from colleagues or seniors
