Ca bon tang dung chung mot ID benh nhan. Hanh trinh cua thuong binh tu diem bi thuong qua phau thuat la mot chuoi lien tuc, co the truy vet — khong phai bon bieu mau giay roi rac.

Tang 1: Cham Soc Dai Han Tai Hien Truong (PFC)

PFC la che do cho doi[1]. Khi benh nhan khong the duoc so tan, ai do phai giu ho song trong 72 gio voi nguon luc han che.

Module PFC tao ke hoach cham soc ky thuat so va theo doi dau hieu sinh ton lien tuc — nhip tim, huyet ap, nhip tho, SpO2, nhiet do, Thang Diem Glasgow — theo cac khoang thoi gian co the cau hinh. Thong thuong moi 15-30 phut.

Gia tri lam sang nam o xu huong, khong phai o cac gia tri rieng le. Mot huyet ap 100/60 co the binh thuong hoac dang bao dong tuy thuoc no la 130/80 mot gio truoc do hay khong. He thong tu dong phat hien cac xu huong nay:

  • Huyet ap giam lien tuc (>10 mmHg moi lan do): tao canh bao WARNING
  • Da dat garrot: tu dong canh bao tai 2 gio (WARNING), 4 gio (CRITICAL)
  • GCS giam ≥ 2 diem: canh bao ngay lap tuc
  • Den gio dung thuoc: nhac truoc 15 phut

Bang dieu khien hien thi mui ten xu huong ben canh moi dau hieu sinh ton — HR 110↗ nghia la nhip tim dang tang. Mot y ta dang quan sat muoi benh nhan co the phat hien ngay nguoi dang xau di ma khong can doc tung con so.

Cong khan cap: Trong tinh huong khan cap, y ta co the ghi nhan dau hieu sinh ton ma khong can tao ke hoach cham soc truoc. He thong tu dong tao ke hoach tam thoi duoc danh dau la cong khan cap. Chien truong khong cho doi hanh chinh.

Tang 2: The Thuong Binh TCCC (DD 1380)

DD 1380 la the thuong binh chuan NATO[2]. O dang giay, no la mot the gap nhet trong quan ao thuong binh hoac buoc vao garrot. No ghi lai co che chan thuong, dieu tri da thuc hien, thuoc da cho, va thoi gian garrot.

Phien ban giay co ba van de trong LSCO:

  1. Bi mat, bi uot, hoac mo di
  2. Khong the sao chep khi ban giao — ai giu the thi giu ban duy nhat
  3. Khong the truyen truoc cho co so tiep nhan

Module TCCC cua xGrid so hoa the nay. Du lieu nhap mot lan va tao ba dau ra:

  • Ma QR: Ma hoa gon cua toan bo tom tat thuong binh. Khi ban giao, tram tiep nhan quet QR va du lieu benh nhan tu dong dien vao. Khong can nhap lai, khong co loi sao chep.
  • Bao cao MIST: Co che, Thuong ton, Dau hieu/Trieu chung, Dieu tri — duoc dinh dang nhu bao cao vo tuyen van ban thuan. Y ta doc thang vao may bo dam ma khong can dinh dang lai.
  • Ban ghi lau dai: The ky thuat so ton tai qua hong hoc thiet bi nho Giao Thuc Phao Cuu Sinh. The giay trong tui benh nhan la ban sao luu, khong phai ban ghi chinh.

Tang 3: Hang Doi So Tan (MEDEVAC)

Khi viec so tan tro nen kha thi, ai di truoc?

Module MEDEVAC duy tri mot hang doi uu tien su dung phan loai chuan NATO:

Uu tienTieu chiDieu kien goi y tu dong
KHAN CAPDe doa tinh mang, so tan ngayGCS ≤8, HA tam thu <90, SpO2 <90%

He thong tu dong goi y muc uu tien dua tren dau hieu sinh ton va thuong ton, nhung bac si co the ghi de. No cung tao yeu cau 9 dong NATO — dinh dang vo tuyen chuan hoa de goi so tan — duoi dang van ban co the sao chep.

Thoi gian cho duoc tu dong theo doi. Khi truc thang den, hang doi cho ban biet chinh xac ai da cho lau nhat o moi muc uu tien.

Tang 4: Phau Thuat Kiem Soat Ton Thuong (DCS)

DCS dao nguoc triet ly phau thuat thong thuong[3]. Thay vi sua chua triet de trong mot lan mo, no dung ba giai doan:
