Anaesthesia is a state of temporary & reversible loss of consciousness, sensation or awareness. It incorporates profound pain relief & amnesia for patients undergoing surgical, medical dental or other diagnostic /therapeutic procedure.
Types of Anaethesia
General Anaesthesia is an anaesthetic Agents /drug induced loss of consciousness, along with pain relief, amnesia and muscle relaxation. The patient needs assistance to maintain her/his breathing & airway control.
Anaesthesiologists help maintain this state by intensive monitoring along with maintenance of a stable state of Breathing &Circulation (Heart & Blood Pressure) and reverse the effects of General Anaesthetic agents at the end of major surgery. They also help continuation of pain relief in postoperative period.
Regional Anaesthesia involves numbing parts of body using either of the two modalities:
- Central Neuraxial blocks :- Spinal & Epidural Anaesthesia : These help to numb preferably lower half of body. Combined Spinal Epidural Anaesthesia gives an advantage of extending anaesthesia &pain relief for longer periods, for relieving labour pain & postoperative surgical pain.
- Peripheral Nerve Blocks, Wherein a specific nerve is blocked preferably using ultrasound guidance for accurate Pain relief &anaesthesia.
Sedation & Monitored Anaesthesia Care (MAC)
This involves inducing light to moderate sleep which helps to relieve anxiety &pain while maintaining arousability. The patient is monitored throughout the procedure by a qualified anaesthesiologist.
The anaesthetic drug is usually injected into the tissue to numb just the specific location of your body requiring minor surgery.
