Group that will undergo POCUS examination

The group that will not undergo POCUS examination

Point of care ultrasound examination

The study will include two groups of patients, POCUS group that will undergo point of care ultrasound (POCUS)examination in addition to clinical evaluation and laboratory investigations and control group that will not undergo POCUS examination but only undergo clinical evaluation and laboratory investigations. Both groups will be compared regarding proportion of accurate diagnosis (at emergency department)in relation to the final diagnosis that will be obtained after patient undergo further imaging techniques to search for sepsis such as chest X-ray or CT to look for chest infection and CT abdomen to confirm intra-abdominal sepsis.

Unlike trauma, dyspnea and shock up till now there is no validated POCUS protocol to evaluate patients with sepsis.

Evaluation of the difference between two groups regarding time taken to reach diagnosis
