- Interventions
- Drug: Oral Nimodipine and milrinone
- Registration Number
- NCT05131867
- Lead Sponsor
- Zagazig University
- Brief Summary
To evaluate the efficacy and safety of oral Nimodipine and IV milrinone combination therapy for management of cerebral spasm after aneurysmal subarachnoid hemorrhage.
- Detailed Description
after being informed about the study and potential risks. All patients giving written consent will be randomized by double-blind manner into 2groups each one containing 15 patients.
Group 1(n =15 ):the patients will receive nimodipine (60 mg/4 hours) orally or via nasogastric tube In group 2(n =15 ): the patients will receive Oral Nimodipine (60 mg/4) will be given orally or in the gastric tube also from the first day of admission, then after the diagnosis of vasospasm is confirmed, start milrinone.

Group Intervention Description Milrinone group Oral Nimodipine and milrinone The patients will receive oral Nimodipine (60 mg/4) will be given orally or in the gastric tube also from the first day of admission, then after the diagnosis of vasospasm is confirmed, start milrinone bolus of 0.1-0.2 mg/kg followed by 0.75mcg/k/min, if no response after 30min increase the infusion to 1-25mcg/kg/min with maintaining CVP 5:8. Norepinephrine (0.01-0.2ug/kg/min) is used only to restore the mean arterial pressure (MAP) to its previous values If there was no recurrence of symptoms after 72 h, we decreased the milrinone infusion by 0.25 mcg/kg/min every 24 or 48 h until discontinuation. If there are any recurrent of symptoms of vasospasm, the patients are placed back on the dose they were previously receiving. If required, another Milrinone bolus is administered if the patient's deficits do not revert12. triple H group nimodipine The patients will receive nimodipine (60 mg/4 hours) orally or via nasogastric tube from the first day of admission, then after the diagnosis of vasospasm is confirmed, Triple H therapy (hypertension, hypervolemia and hemodilution) will be started. norepnnephrine (0.01-0.2ug/kg/min) to mentain main arterial blood pressure \>100mmhg and hypervolemia to maintain the CVP around 12---14 mmHg and hemodilution to maintain the haematocrit between 30% and 33%.
- Primary Outcome Measures
Name Time Method Concentration of transcutaneous cerebral mixed oxygen saturation every 24 hours up to 1 week by forehead bilateral interconnected adhesive probes
- Secondary Outcome Measures
Name Time Method Number of participants restore of the previous conscious level and motor state(Percentage of drug success) 1 hour after administration of milrinone and 2 hours after administration of triple H therapy restore of the previous conscious level and motor state
value of Modified Rankin scale 3,6,12 monthes after drug administration Level 0: no symptoms Level 1: no significant disability, despite symptoms; able to perform all usual duties and activities Level 2: slight disability unable to perform all previous activities but able to look after own affairs without assistance Level 3: moderate disability; requires some help, but able to walk without assistance.
Level 4: moderately severe disability; unable to walk without assistance and unable to attend to own bodily needs without assistance Level 5: sever disability; bedridden, incontinent and requires nursing care and attentionNumber of participants develop one of adverse events after administration of the study drugs up to 30 days hypotension ,bradycardia,hypotesion
Total ICU and hospital stay up to 30 days after administration of the study drugs mortality rate 30 day after administration of the study drugs Number of participants died within 30 day after administration of the study drugs
Glasgow Outcome Scale 3,6,12 monthes after drug administration 1. Dead: As a direct result of brain trauma, or ... due to secondary complications or other complications" "2. Vegetative State: Patients who remain unresponsive and speechless...." "3. Severe Disability: The The patient is conscious but needs the assistance of another person for some activities of daily living every day....." "4. Moderate Disability: Such a patient is able to look after himself at home, to get out and about to the shops and to travel by public transport. However, some previous activities, either at work or in social life, are now no longer possible by reason of either physical or mental deficit...." "5. Good Recovery: This indicates the capacity to resume normal occupational and social activities, although there may be minor physical or mental deficits...social outcome should be included in the assessment here, such as leisure activities and family relationships..
value of Glasgow coma scale every 24 hours up to total days of ICU and hospital stay with minimum scale vlue of 3 is the worst and maximum value of 16 indicate better outcome
Number of participants having cerebral infarction (cerebral infarction incidence) every 48 hours up to 1 week detected by computed tomography
