Anaesthesia for patients in general surgery, ENT, obstetrics and gynaecology, paediatric surgery,
plastic surgery, cardiothoracic surgery, orthopaedic surgery, neurosurgery, urological surgery
and ophthalmology. Pre-operative ward rounds (history taking, physical examination, relevant
investigations) and premedication. Intra-operative management of patients (general anaesthesia,
regional techniques, plexus and nerve blocks). Airway management and ventilation. Recovery
room care. Postoperative care- monitoring, pain management etc. Management of critically ill

Course Justification
Good surgical outcome depends on sound scientific knowledge of anaesthesia which includes
physiology, anatomy, pharmacology and clinical medicine related to the specialty. Pain is the
most common presenting symptom of patients and this is a specialized area in anaesthesia in
which the student must have basic knowledge. Critical care involves airway management,
support of the respiration and circulation for which the student must also have a sound
knowledge in order to be able to manage such patients upon graduation.
