Occurs when IV fluids or medications accidentally leak into the surrounding tissues instead of remaining in the vein. This can cause swelling, pain, redness, and tissue damage at the IV site. 

IV Infiltration

100

Involves receiving blood or blood components intravenously to replace blood lost or to increase low blood levels.

Blood transfusion

100

It has A antibodies in plasma.

Type B

200

The patient experiences analgesia and amnesia but remains conscious. 

Stage 1 (Analgesia) 

200

Refers to surgical procedures performed primarily to aid in assess a condition or disease. These exploratory operations allow direct visualization and biopsy of tissues or organs that cannot be adequately assessed through non-invasive tests alone. 

Diagnostic surgery

200

A severe form of wound dehiscence where the contents of the abdomen, such as the intestines, protrude through the separated surgical wound. It is a medical emergency requiring immediate intervention. Sterile gauze soaked in sterile saline is placed on the incision, and the surgeon is notified immediately.

Universal blood recipient 

AB+

Dehiscence

300

Universal donor

O-

300

It has no antibodies in plasma.

Type AB

400

This is the ideal stage for surgery with complete unconsciousness, muscle relaxation, and depressed reflexes.


Stage 3 (Surgical Anesthesia)

400

It aims to restore form and function to body parts affected by trauma, disease, or congenital defects.

Reconstructive surgery

400

Refers to uncontrolled bleeding that occurs inside the body. It can happen due to trauma, ruptured blood vessels, organ damage, or certain medical conditions.

Internal bleeding
