The skill stations are becoming the essential part of undergraduate medical training but availability and uniformity in their structure and functioning are still not universal across institutions. In the absence of cutting edge technology or paraphernalia in newer medical colleges, innovative and creative use of easily available materials to make models for teaching, training, and assessment purpose is highly desirable and attempts should be made by teachers and students both to hone their skills in this regard. A simple intravenous catheterization, which is one of the many essential core skill, is presented here as an example to generate the interest of fellow colleagues.

  Introduction Top

The National Medical Commission (NMC) has developed a road map to provide a complete makeover to the medical education aiming competency-based learning.[1] Competency-based medical education is targeted to make the curriculum objective based among its many other features. The Indian Medical Graduate (IMG) is supposed to absorb key characteristics that are required of him and duly mentioned in NMC publications. Practical skill training module has been a key component of new NMC curriculum.[2] Skill laboratories are also to be formed for this purpose in each college and certifiable procedural skills are described for undergraduate learning in this module. In a developing nation like India, indigenous technology or low-cost innovation would also be required to cater the students amidst disparity in the facilities available across institutions.

  Technique Top

We describe an easy method to develop a small model or station to describe or demonstrate intravenous (IV) cannulation method by utilizing easily available material in the hospital. The materials required are as follows: A surgical glove, a card board rectangle, a urinary catheter, and pins (drawing or board pins). These materials are inexpensive and are part of hospital environment [Figure 1]a. A short tube is cut out of urinary catheter straight part to make the vascular channel or vein. The tube shall be placed inside the gloves in one of the finger sections and all five fingers can also have similar insertions if required [Figure 1]b. The whole arrangement is to be fixed over a cardboard rectangle with the help of pins that it resembles a hand lying on a board. Cotton can be filled inside gloves to make it fluffy. Now this rectangle can be placed in a table for demonstration or teaching purpose. The students can be asked questions like “what are steps in performing IV cannulation?” “What are things to be taken care of before the procedure?,” “what is the stepwise technique you would use?” etc.

  Discussion Top

Skill laboratory establishment and their functioning is one of many key steps that are a departure from old curricula.[2],[3] Various factors would result in uniformity in skill laboratories across the medical colleges in the country like availability of funds among many factors. The state of art mannequins, models, and related paraphernalia is supposed to be included in skill laboratories which will be instrumental to provide basic simulation training in core skills to the IMG.[4] In the initial stages of the program or in a newly established college, delay in development of these skill labs is a potential problem. Apart from it continuous improvement in facilities and maintenance would be perennial problems. The uniformity of the material available within any skill laboratory across the states is also a doable but distant dream.

Till the time, these laboratories are the part of standard training, there is the scope for indigenously designed models for teaching or training purposes.[5] Innovative usage of locally available materials in creative ways to make things that make the concepts of medicine easy to understand or teach is good alternative. Similarly, models that impart basic skill training would be highly desirable. Another advantage of these methods would be their use in assessment/evaluation purposes. Objective structured clinical examination or objective structured practical examination can utilize these models for assessment tasks. The faculty of medical colleges and students also need to address local deficiency of high-fidelity skill lab with the help of creative imagination to design indigenous products or models for teaching and training which considering the diverse and talented pool of teachers seems doable. The development of sense of enquiry and creativity to solve daily problems will also serve as the big life lesson for all involved in this process.
