refractory septic shock, catecholamine resistance septic shock, terlipressin, methylene blue
Brief summary
The ICU mortality rate of patients with septic shock was still high upto 54.1%.In first 6 hours of resuscitation, the goals of resuscitation in sepsis shock after adequate fluid resuscitation is MAP ≥65 mmHg. In refractory septic shock patient, prolong shock correlate with poor outcome due to multiple organ failure. Alternative vasopressor in septic shock with catecholamine resistance has been studied such as terlipressin, methylene blue * Terlipressin (TP) mediate vasoconstriction via V1 receptors coupled to phospholipase C, and increases intracellular Ca2+ concentration * Methylene blue (MB) directly inhibits nitric oxide synthase (NOS) by inhibit the enzyme guanylate cyclase (GC)
Interventions
after defined refractory shock (need NE\>0.5 mcg/kg/min) add Methylene blue 1 mg/kg iv drip then 2 hr later drip 0.5 mg/kg/hr\*4 hr (intervention add on to standard care)
after defined refractory shock (need NE\>0.5 mcg/kg/min) add terlipressin 1 mg IV then repeated dose 20 min later if unstable BP (intervention add on to standard care)

Primary
| Measure | Time frame |
|---|---|
| mortality rate | 7 days |
| time to wean of vasopressor | through complete weaning off vasopressor, an average of 24 hours |
| ICU duration | through out off indication need ICU care, an average of 7 days |
Secondary
| Measure | Time frame | Description |
|---|---|---|
