Anaesthesia and Recovery
The anaesthesia nurse’s role: monitoring, medicines and emergency management
What an anaesthesia nurse needs to observe, prepare, verify and communicate: monitoring, medicines, airway readiness and emergency support in the operating room.
The first thing that strikes you when you work beside the anaesthetist is how much information arrives at the same time.
The monitor shows blood pressure, heart rate, oxygen saturation, temperature, ventilation and much more. Meanwhile, the patient is being positioned, medicines must be ready, the airway equipment checked and the team is completing the preparations for surgery.
Before the surgeon can begin, the patient is already entrusting their life to the anaesthesia team: the anaesthetist and the nurse working alongside them. Their aim is not simply to prevent pain. They must help maintain the patient’s vital functions and clinical stability throughout the procedure. It is an enormous responsibility, often less visible than the surgical field, and it begins before the incision.
At first it is easy to think the job consists of watching many numbers and preparing whatever is requested as quickly as possible. Over time I understood that the real task is different: connect what you see with what is happening and help make the continuation of the procedure safe and possible.
That is the role of the nurse working alongside the anaesthetist: not to replace medical assessment, but to support continuity of care through observation, preparation, verification and communication.
The exact activities depend on local organisation, professional scope, prescriptions and institutional protocols. The underlying logic remains the same: a data point becomes useful when it is recognised and interpreted in the context of what is happening.
The monitor is not the patient
ECG, blood pressure, SpO₂, capnography, temperature and other forms of monitoring continuously generate data. No single number tells the whole story.
A falling oxygen saturation may indicate a real problem, but it may also reflect a displaced sensor or a poor signal. Low blood pressure means something different depending on the stage of anaesthesia, bleeding, patient position and medicines administered.
So I do not look only at the value. I ask three questions:
- Why is this value changing?
- What was happening to the patient at that moment?
- Is the value consistent with the other signals and with the patient?
The first step is to notice the change. The next is to verify the quality of the reading and its context. The reason is to avoid two opposite errors: missing an important signal or reacting to an artefact as if it were a crisis.
Monitoring does not mean staring at a screen. It means reading a situation while keeping your eyes on the patient.
Before induction I prepare possibilities, not just equipment
Induction concentrates many critical steps into a short period. The patient loses consciousness and the ability to protect their own airway; the margin for retrieving forgotten equipment can quickly become very small.
Being ready therefore does not mean having many items on the trolley. It means knowing:
- which monitoring is planned and whether it is ready;
- which devices are required for the procedure;
- where the planned alternative equipment is if difficulties occur;
- which medicines have been prescribed and how they must be identified and checked;
- who will do what.
The question that guides me is: if the next step did not go as planned, what would need to be immediately available?
That is not pessimism. It is preparation.
To see this reasoning inside the wider theatre workflow, read A day in the operating room: what really happens from the first to the last case.
The trolley must stay usable under pressure
An organised trolley is useful. An organised trolley during an emergency is even more useful.
Medicines, airway devices, vascular-access equipment, infusions and emergency supplies must be checked and positioned according to local organisation. It is not enough to know that they are “there”. I need to be able to find, recognise and verify them.
A rule that applies throughout the operating suite returns here: present does not mean ready.
A package may be present but damaged. A device may be available but incomplete. A medicine may be in stock but not in a sufficient quantity.
Preparation is not measured by how much equipment is visible. It is measured by how many critical steps have already been made possible.
Medicines: competence is not working from memory
Anaesthesia involves high-risk medicines in an environment where time pressure, noise and interruptions can favour error.
For a long time, the image of an experienced professional was someone who remembered everything without checking anything. It is a misleading image.
Knowing indications, expected effects, risks and the required management is essential. Safety also depends on correct identification, prescription, concentration and dilution checks, labelling, traceability and compliance with local protocols. Where a shared check is required, it is not a sign of insecurity. It is a barrier against error.
When I receive an important request, I close the communication loop:
- I repeat the medicine name, concentration or information requested;
- I prepare it according to prescription and procedure;
- I show or communicate what I have prepared;
- I wait for confirmation when required.
Memory helps the work. Verification protects the patient and the professionals involved.
The same principle is explored in Closed-loop communication in the operating room.
During surgery I watch trends, not only crises
One abnormal value can attract attention. Often, however, the trend shows that something is changing before a crisis becomes obvious.
Blood pressure gradually falling, heart rate rising, a changing capnography trace or a decreasing temperature: the nursing role is to recognise the change, check that the data are reliable and communicate the change clearly.
I do not need to make a diagnosis. I need to make relevant information visible so that the anaesthetist can assess it.
The anaesthetised patient cannot tell you what is happening
An anaesthetised patient cannot report pain, pressure, an unnatural position or traction on a limb.
That makes positioning a clinical care activity, not a task that ends once the patient is lying on the table.
I check alignment, protection of pressure points, limb position, accessibility and stability of vascular access and devices, according to local procedures and shared team responsibilities. If the operating table changes position or equipment is moved, the check starts again.
A correct position at the beginning does not remain correct by definition. It must still be correct after every change.
In an emergency, clarity comes before speed
A difficult airway, haemodynamic instability, an adverse reaction or haemorrhage changes the pace of the room. The more requests that arrive, the greater the risk that information will be lost or misunderstood.
At those moments I try to reduce invisible work:
- repeat high-risk information;
- communicate what is available and what is missing;
- keep the workspace clear and organised;
- report immediately any doubt or value that does not make sense;
- follow local procedures and the directions of the responsible anaesthetist.
Anticipation does not mean guessing or acting outside your role. It means knowing the sequence well enough to prepare what may be needed and to recognise early when the situation is changing.
The shift in perspective
At first it is easy to think that a good anaesthesia nurse is the person who carries out every request quickly.
I see it differently now.
The reliable professional is the person who notices what could otherwise be missed: a trend, a medicine that needs verification, an incomplete connection, a device that is not ready or a step that is unclear.
Speed comes with experience and time. Safety starts earlier, with a method:
observe, connect, verify, communicate.
Those four actions complete the picture. The monitor shows the data. Context gives the data meaning. Verification reduces uncertainty. Communication allows the team to act together.
An exercise for your next shift
Choose one phase only: preparation, induction, maintenance or emergence.
For that phase, make four columns:
- what I need to observe;
- what I need to have available;
- which change I need to recognise;
- which information I need to communicate without delay.
Then compare your map with an experienced colleague.
Do not try to memorise all of anaesthesia at once. Build one sequence at a time. When the steps begin to connect, the monitor stops being a collection of numbers and the trolley stops being a collection of drawers.
The next step
The anaesthesia team’s work does not end when surgery finishes. The patient enters a phase in which the effects of anaesthesia, pain and possible complications still need close observation.
