What is an average (or minimum) number of the following procedures that a student should do/ have done by the end of 4th year, before starting residency: LP vaginal deliveries flex sig other endoscopies casting central line placement arterial line intubation vaginal exam/pap chest tube Feel free to add to the list. I realize there may be a great deal of variation from school to school. This is why I am asking for averages, or what is felt to be the minimum acceptable level. If you would prefer to just share your personal experiences/numbers that would be great as well. thanks.
