He is a specialist who is specially trained to provide the following services:-
When patient has to undergo an operation, the anaesthesiologist visits the patient to reassure him and discuss the type of anaesthesia to be used. He also identifies any other concurrent medical conditions, which may affect the anaesthetic and takes steps to stabilize these conditions. He may also order a sedative the night before surgery to allow the patient a restful sleep.
ANAESTHESIA FOR SURGICAL PROCEDURES
Most patient scheduled for an operation are fearful of pain and wrought with anxiety. The anaesthesiologist's role is to ensure that a patient has no pain throughout the procedure. He may do so by the following techniques:-
The patient is asleep and is unaware of the operation until its over when the anaesthesiologist will wake him up.
The patient is awake but feels no pain because the operative site, e.g. Hand or legs is made pain free. If the patient is anxious, the anaesthesiologist may make the patient calm or sleepy by the administration of appropriate drugs.
The patient is also awake. This procedure is performed by inject of local anaesthetic medication to numb only a small area of nerves at the site where the surgeon plans to operate such as for cataract surgery.
After the operation, the patient may feel pain for a day or two. The anaesthesiologist can help to relief the pain by several measures. One modern method is the use of a computer-aided device, which delivers a pain killer every time the patient presses a button. The patient is therefore in full control of his own pain relief.
OBSTETRIC PAIN RELIEF
It is now possible to deliver a baby without labour pain. The anaesthesiologist can perform an epidural to give Pain relief throughout the entire labour and until the baby is delivered.
EMERGENCY MANAGEMENT AND RESUSCITATION
A seriously ill patient can suddenly stop breathing or develop a cardiac arrest. The anaesthesiologist is part of the team who will resuscitate such a patient and restore him to life. This setting can happen in the Accident & Emergency Department when a patient is just admitted and occasionally in others parts of the hospital.
MANAGEMENT OF CRITICALLY ILL PATIENTS IN THE INETNSIVE CARE UNIT (ICU)
Very ill patients need cardio-respiratory support in the intensive care ward. Such as patients have an unstable blood circulation and unable to breath well. the also have poor nutrition and need very close monitoring. Here, the anaesthesiologist acts as an intensivist and breathes for the patients with the help of a life support machine (ventilator) until the patient's condition improves.
Helpful Information for Patients
When an operation is scheduled under a general anaesthetic, the anaesthesiologist requires the patient to be fasted for at least 4 hours. An empty stomach is important during the induction of an anaesthetic to prevent any food debris from entering the patient's lungs when he is unconscious. Aspiration of stomach contents into the lungs can be fatal. This is why it is important that a patient should NOT eat before an operation.
