Details |
| Intervention |
Group A: Vasopressin discontinued first, followed by norepinephrine.
|
Baseline data will be collected before the discontinuation of any vasopressor, including
demographic information (age, sex, weight, primary diagnosis), comorbidities (such as
diabetes, hypertension, chronic kidney disease), severity scores (SOFA and APACHE II),
source of sepsis (pulmonary, urinary, abdominal, etc.), vasopressor doses (norepinephrine and
vasopressin), hemodynamic parameters (mean arterial pressure, heart rate, respiratory rate),
and lab values (lactate levels, creatinine, urine output if available). Our standard practice of care
in ICU is discontinuation of vasopressin first followed by noradrenaline which will be the control
arm for the study. The sequence of vasopressor discontinuation will be recorded, with patients
assigned to either Group A, where vasopressin is discontinued first route IV DOSE 1U PER HOUR DURATION MAP TARGET MORE THAN 65 MM HG |
| Comparator Agent |
Group B: Norepinephrine discontinued first, followed by vasopressin.
|
Group B where norepinephrine is discontinued first This process will be monitored but it will not be influenced by the study team Monitoring begins at the moment of discontinuation of the first vasopressor After the first vasopressor is discontinued hemodynamic parameters such as MAP heart rate respiratory rate and SpO2 will be measured at multiple time points just before discontinuation T0 one hour after discontinuation T1 three hours T3 and six hours T6 ROUTE IV DOSE 0.1 MCG PER KG PER HOUR DURATION MAP TARGET MORE THAN 65 MM HG

Brief Summary
|
Septic shock is a severe and life threatening form of sepsis marked by major disturbances in circulation cellular function and metabolism leading to high mortality. It is commonly defined by persistent low blood pressure requiring vasopressor support to maintain adequate mean arterial pressure along with elevated serum lactate levels despite proper fluid resuscitation. Even with improvements in intensive care practices septic shock continues to carry high rates of illness and death worldwide. A key aspect of septic shock management is the use of vasopressors to support blood pressure and organ perfusion. Noradrenaline and vasopressin are commonly used agents. Noradrenaline is widely accepted as the first line vasopressor because it effectively increases vascular tone with a relatively lower risk of heart rhythm disturbances. Vasopressin works through a different mechanism and is usually added when blood pressure remains low despite adequate doses of noradrenaline. While initiation of vasopressors is well studied the best method for reducing and stopping these drugs once the patient stabilizes remains unclear. In routine practice the order of vasopressor withdrawal often depends on clinician preference rather than strong evidence. Some studies suggest that the sequence of discontinuation may affect blood pressure stability need for restarting vasopressors length of intensive care stay and overall outcomes. Stopping a vasopressor too early may cause instability while prolonged use may increase the risk of side effects related to each drug. Noradrenaline has a short duration of action and can be adjusted easily whereas vasopressin has a longer lasting effect and is usually given at a fixed dose. These differences suggest that the order of weaning may influence patient recovery. However high quality randomized trials comparing these strategies are limited. This study aims to compare noradrenaline first versus vasopressin first weaning strategies in patients with septic shock receiving both agents. By evaluating outcomes such as blood pressure stability need for restarting vasopressors intensive care stay and mortality this trial seeks to provide evidence to guide clinical decision making and improve care for patients with septic shock. |
