Keywords For Your Surgical Rotation In Med School

An Ongoing Surgery

Bonjour everyone! Today, I’m going to share with you some high yield keywords that should hopefully help you breeze through your surgical rotations in med school. Call it a checklist if you will. The objective is to facilitate memory recall and help you gear up with areas that you just have to familiarize yourself with, ideally before the start of your rotations. Understand that these are just keywords, with a special emphasis on surgical instruments, and you’ll really need to read some good books to develop your knowledge base. For a rapid-fire review I suggest Surgical Recall. For basic surgical skills, you might like RM Kirk’s Basic Surgical Techniques. It is also a good idea to refer to specific sections (for pictures of incisions, instruments, etc.) of a good reference book on the surgical specialty you’ll be rotating in. Finally, like we all know, surgery is an area that is incredibly skill based and different people have different preferences when carrying out the same thing – be it tying a knot, controlling a bleeder or what have you. You’ll learn to modify the way you do things depending on the specific ways of your surgical team.

I’ve also interspersed keywords specific to two areas that I have an interest in with regards to surgery, or rather surgical oncology to be exact – general thoracic surgery and colorectal surgery.

I shall be updating this list as the need comes. Comments, corrections and feedback are always welcome! Bye for now :-)!

Know The Institutional Setup

The Building And Its Parts

  • Floor (a.k.a the inpatient ‘ward’. The terminology comes from the fact that often high rise hospitals dedicate entire floors to a specific inpatient service. Eg: Pediatrics floor, ICU floor, etc.)
  • Nursing Station
  • Fellows room / doctors’ backroom (seating area for all of the doctors on a floor with computer workstations, etc.)
  • Conference room (where meetings between doctors or between doctors and their patients can be conducted.)
  • Storage room (a floor typically keeps its supplies in a ‘storage room’)
  • Treatment room (some floors will have a designated ‘treatment room’ for minor procedures such as gynec exams, etc.)
  • Clinic (the outpatient clinic)
  • SDH (‘surgical day hospital’, a section of the building dedicated to outpatient based procedures like colonoscopies, etc.)
  • PACU (post-anesthesia care unit, a.k.a the ‘post-op’ ward. Sometimes this area is also were patients scheduled for surgery stay during the immediate pre-op for marking of the surgical site, any last minute changes in consent, etc.)
  • OR suite (where all of the main ORs are)
  • Core (some facilities have the entire suite of ORs categorized by specialty. A set of ORs meant for a particular specialty requires its own specific instruments, computer monitoring, etc. A ‘core’ is an area adjacent to these ORs that houses all of this equipment. Sometimes a core will have dedicated OR techs to look after the functioning of its set of ORs.)
  • OR Suite Control Room (located adjacent to the suite of ORs. Helps with the logistics and monitoring of activity in all of the ORs. Eg. movement of patients in and out, updating the progress of surgeries listed on the ‘greaseboard’, etc.)
  • ICU
  • ER (sometimes known by other names such as “Urgent Care”. Referred to as the “A&E” or “Casualty” in many other countries. The ER is often the first point of contact between a patient and a care provider at a hospital.)
  • Swing (as in a particular section of a ward)
  • Pneumatic tube (on a floor eg. to collect and send blood samples, etc. to a lab)

The Staff

  • Intern
  • Resident
  • Chief Resident
  • Fellow
  • Attending
  • Hospitalist (a physician who is solely involved with inpatient care and who does not see outpatients.)
  • RN (Registered Nurse)
  • NP (Nurse Practitioner)
  • PA (Physician Assistant)
  • Floor Nurse
  • Nursing Assistant
  • IV Nurse/Team (puts in i.v. lines, etc.)
  • Floor Clerk (looks after phone calls to the floor, transfer of patients to and from the floor, etc.)
  • Preop Nurse
  • Circulating Nurse
  • Scrub Nurse (a.k.a. ‘scrub tech’)
  • OR control room nurse/tech
  • Wound Nurse (some facilities will have a wound nurse dedicated to care of specific wounds in a given area, like a colostomy site.)
  • Wound Team (sometimes there’s a special team of nursing staff that takes care of stuff like ‘wound-vacs’, plastic surgery skin flaps, etc.)
  • Orderly (responsible for moving patients around in wheel-chairs, helping with hygiene, etc. People from the Indian subcontinent might be familiar with this job as the ‘ward boy’ [male] or ‘daya’ or ‘aaya’ [female].)
  • Nutritionist
  • PT/OT (Physiotherapist – can be specialized like ‘pulmonary PT’, etc.)
  • Case Manager (usually there’s at least one for a selected group of patients on any given floor. Also known as the ‘social worker’, this person deals with financial and ethical issues surrounding the day to day care of patients. Examples of these activities include setting up hospice, medical insurance issues, dnr and health proxy issues before, during and after surgery in concert with the doctors, etc.)
  • Other techs (portable x-ray tech, EKG tech, etc.)
  • Chaplain (or priest)

Before The OR

  • The Greaseboard (the live electronic display of OR events and surgeries on a monitor)
  • Surgical scrubs
  • Mask – with or without eye shield. Learn to identify the individual sides of a mask. A mask will not allow air to pass freely from the wearer’s mouth to the other side. But it will allow air to easily pass from the other side to to the wearer’s mouth. The objective is to prevent contamination of the surgical field, but not complete prevention of inhalation of airborne droplets.
  • Respirator – Unqualified, it filters air from the outside to the inside. Some will filter air in both directions.
  • Goggles
  • Shoe covers. ‘Booties’ are special kinds of shoe covers that cover the feet all the way up to and including the ankles.
  • Cap
  • Wet scrub
  • Dry scrub – a chemical that you just rub on without having to wash away.

In The OR

  • Step (a wide platform with four short legs on which one could stand on)
  • OR table (that usually has an electronic control)
  • Positions of the OR table – Trendelenburg, Reverse Trendelenburg, Flat, ‘Drop-the-shoulder’ (where the table is ’tilted’ right or left, ‘Bend’ (where the table is bent in the middle, such that it forms an arch with a convexity facing the ceiling.)
  • OR flatscreen monitor (for displaying the surgery, pathology slides, etc.)
  • Time-out (the OR staff including the surgeons and anesthesiologists run through a safety checklist before, during and after the surgery. Ex: saying aloud the name of the patient, age, gender, scheduled surgery, incision site, counts of mops and instruments, etc.)

  1. I have a test coming up where I have to visually be able to tell the difference between a Bard-Parker knife handle #3 and Bard-Parker knife handle #4. I only have the pictures in my book and whatever I can find on-line and they both look the same to me. The longer I look, the more alike they seem. Both are 5 inches long and have rulers on one side. What’s the difference? I know they hold different blade but these won’t have blades on them and they won’t be next to each other for comparison.

    • The longer I look, the more alike they seem. Both are 5 inches long and have rulers on one side. What’s the difference?

      As far as my experience with these handles goes, I’ve always found the size engraved on the end of the BP knife handle opposite to the end that holds the scalpel.

      If that doesn’t help, you might also try asking your scrub nurse/tech to clarify on this issue before the test comes up. They tend to be more knowledgeable than most other people when it comes to identifying instruments.

      Good luck on the test! And please do visit again!
