 So I'm Captain Ralph Butler. I'm a general surgeon slash colorectal surgeon from Navy Medical Center Portsmouth here augmenting second medical battalion following under CLB2. So a mass casualty drill is when we test the resources of the medical system to its limits. We try to push our boundaries and see how how we can do with multiple patients. We define a mass casualty as any time we overwhelm our system. Well, we learn a lot of our communication process as well as review the medical and surgical care and also work on the medical regulating, which is the patient transport and tracking. It depends on where we are in the deployment cycle. Prior to deployment they happen we do field exercises and work up to deployment just like other units. On a non-deployment cycle, we'll do them at least once a year. The members that are organic to second medical battalion certainly do them more frequently. Well, we have notionalized points of injury and patient scenarios. So we start to drill from the very beginning at the point of injury through the communication piece, the triage piece, which is where we sort the patients out and figure out where they're going to go. The patient arrival into the shock trauma platoon or the ER, the initial treatments, and then figuring out who's going to go into the operating room or get transported to a higher echelon of care. Yep. So Chief Hospital Corpsman Matthew Scott Federoff and I'm the senior enlisted leader for the first SDP team with second medical battalion, Charlie Company. Mass casualty drill is a scenario that bases an overwhelming amount of patients or trauma to the team that we currently have. There's pretty much any overflow of patients that overwhelms the capabilities that we may have either doing with personnel-wise or supply-wise. So the purpose of the mass casualty drill is actually prepare our team. And so we can all work together, talk to each other, have a good flow of communication, treat the patients as they come in, get them stabilized, hopefully not needing any loss of life, so we can get to the next echelon level of care. What we expect to get out of the drills is for everyone to get more familiar and more comfortable with their treatment that they provide, get familiar with the equipment that we use to help stabilize the patients, the communication flow, obviously. And we want to make sure we get to prevent any loss of life overall. We try to run them on once a quarter, once we're in med battalion. And again, that's just keep our proficiency up and make sure that we all communicate well and keep our own, our skills to where they need to be. Things take place during drills. That's kind of a loaded question. So we've got a wide range of cross-training that happens. So we try to utilize the pro-staff of our medical officers, medical doctors to help teach and train our corpsmen how we can better treat and stabilize patients once they get in. So we want to get comfortable with the equipment. We want to get comfortable with each other, with the communication. The med-rig team, we want to make sure they're comfortable with the overwhelming amount of information that they receive so they can actively track and triage patients as they come in for our dental team who acts as our triage team as they come in. We want to make sure they get comfortable with making the right call on the triage levels as patients arrive in. HM2 Timothy Moore with CLB2 surgical company, TAD from Second Medical Battalion and I work in combat trauma management. A mass casualty drill is something that a surgical company internally conducts upon deployment whenever they deploy to ensure that their set processes function adequately in support of numerous casualties. Planning for upcoming deployment takes place months before you actually deploy. What the mass casualty drill actually does is it reinforces people's confidence in the system and in the established guidelines that are put forth. It also identifies weak points that might be able to be improved upon so that we can provide the best patient care if and when that actually does occur. That question entirely depends on the unit. A good unit conducts them fairly regularly, but there's no set period. So during the casualty drills, we stress every section of the surgical company from the medical regulating section which actually receives the call of there's incoming casualties to the triage section, the shock trauma platoon and the forward resuscitative surgical system. It forces them to think on their feet as casualties come in. We only have one operating room bed. So they have to think of that as an asset that has to be used properly. You can only use one, have one patient in the emergency, I'm sorry. You can only have one patient in the operating room at a time. So you have to be able to hold on to and stabilize patients. In the rest of the system without overloading yourself.
