Abstract:
We investigated the relationship between the presence of hypothermia in infection and mortality in 233 infectious critically ill patients. The adjusted hazard ratio for death at 28 days in the low body temperature group was 3.30 compared with the high body temperature group. The proportion of appropriate antimicrobial therapy significantly decreased with decreasing body temperature. The proportion of medical records that documented body temperature abnormality in the low body temperature group (33%) was significantly lower than that in the high body temperature group (69%). Delayed antimicrobial therapy in patients with hypothermia, which may be due to poor recognition by physicians, could result in mortality.

The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.
Step 3: Assess the patient's...
