Detailed Description
Sepsis induced encephalopathy is the most frequent sepsis related organ dysfunction. It appears early during the course of infection, often before any other organ involvement in up to 70% of hospitalized septic patients and is associated with significant change of cerebral circulation caused by redistribution of blood flow during sepsis that accompanies the abnormal inflammatory response during an infection, in absence of direct central nervous system involvement.

Other: Transcranial doppler pulsatility index guided protocol
Norepinephrine titration that will be guided by Transcranial doppler pulsatility index.
|
| Active Comparator: Mean arterial blood pressure guided protocol Norepinephrine titration that will be guided by Mean arterial blood pressure (MAP). |
Other: Mean arterial blood pressure guided protocol
Norepinephrine titration that will be guided by Mean arterial blood pressure (MAP).

Outcome Measures
Primary Outcome Measures
- Intensive care unit (ICU) mortality [28 day or till death which earlier]
Incidence of Intensive care unit (ICU) stay will be recorded
Secondary Outcome Measures
- Mean arterial pressure [24 hours]
Fluid resuscitation will be started using crystalloids at a rate of 4 to 6 ml/kg with reevaluation after 15 minutes. If MAP is still less than 65 mmhg, fluid resuscitation should be continued at a rate of 4 to 6 ml/kg with reevaluation after another 15 minutes up to 30 ml/kg. Vasopressors will be started if the patient is still hypotensive during or after resuscitation without delay even peripherally to avoid delay until central venous access is secured (norepinephrine is the first line agent preferred over other vasopressors).
- Norepinephrine titration [24 hours]
Fluid resuscitation will be started using crystalloids at a rate of 4 to 6 ml/kg with reevaluation after 15 minutes. If MAP is still less than 65 mmhg, fluid resuscitation should be continued at a rate of 4 to 6 ml/kg with reevaluation after another 15 minutes up to 30 ml/kg. Vasopressors will be started if the patient is still hypotensive during or after resuscitation without delay even peripherally to avoid delay until central venous access is secured (norepinephrine is the first line agent preferred over other vasopressors).
- Cerebral perfusion pressure [24 hours]
Cerebral perfusion pressure (CPP) will be done using transcranial doppler.
- Outcome of encephalopathy [28 day]
Encephalopathy outcome at ICU discharge using Glasgow coma scale (GCS)
- SOFA score [Up to 4 weeks.]
SOFA score at ICU admission and discharge.
- Length of ICU stay [At least 28 days]
Length of ICU stay
