Mottling score and central venous oxygen saturation are described as a clinical evaluation of tissue perfusion. This study describes mottling incidence and mottling score in septic shock patients according to central venous oxygen saturation.

This study prospectively analyzed the data of patients admitted to our ICU between October 2022 to December 2022. All septic patients in whom the ScvO2 was measured and mottling scores were evaluated were included. This study enrolled patients aged ≥ 18 years in septic shock. Those excluded have peripheral arterial disease, black skin, cutaneous infection of the lower limbs, pregnancy, and relative refusal. The characteristics of patients were recorded at admission (H0), including demographics (age, sex, body mass index (BMI), admission the Acute Physiology and Chronic Health Evaluation (APACHE II) score, Glasgow Coma Scale (GCS) and sequential organ failure assessment (SOFA) score. Variables such as plasma lactate level, daily urine output, plasma creatinine level, the ratio of arterial oxygen pressure related to inspired oxygen fraction (PaO2/FiO2), hemoglobin level, heart rate, mean arterial pressure, pulsatile saturation in oxygen (SpO2) and body temperature were recorded at H0 and 6 hours after initial resuscitation (H6).

Inclusion Criteria:

• patients aged ≥ 18 years in septic shock.

Exclusion Criteria:

• patients having the peripheral arterial disease
• black skin,
• cutaneous infection of the lower limbs
• pregnancy
• relative refusal

All patients aged ≥ 18 years in septic shock
