Based on Bailey & Love. Any final year student, intern or a PG aspirant can attend the session. At the onset, I will share some questionnaire. You should answer them. Next my class and then post session assessment. This is basically about the investigations in a Surgical patient. Investigations in general and disease specific. Investigations can be categorized into basic, diagnostic, advanced based on the purpose of the investigation in choice. Also can be categorized as invasive or Non invasive depending on the how our body is handled. Can be categorized into blood, urine etc based on the sample. Can be categorized into biochemical, microbiological, pathological. I will touch the different investigations in general. Few examples of different investigations in different diseases. I will also explain the sequence of ordering the investigations. Advantages and disadvantages of different investigations. Alternatives also. I will discuss previous questions in MCQs or short or long answers.
