- Registration Number
- NCT03596060
- Lead Sponsor
- Larissa University Hospital
- Brief Summary
This study compares general to regional anesthesia concerning morbidity and mortality in patients older than or equal to 65 years old who receive clopidogrel and are to be submitted in hip fracture surgery. Half of participants will receive general anesthesia the first 48 hours and the other half will receive regional anesthesia after 5 days of the discontinuation of clopidogrel.

Group Intervention Description Regional anesthesia Chirochaine Hip fracture patients older or equal to 65 years of age, who receive clopidogrel, will will be randomly assigned undertake surgery under regional anesthesia (spinal) at least 5 days after the discontinuation of clopidogrel. Anesthetics to be used are chirochaine 0.5% and fentanyl. General anesthesia Fentanyl Hip fracture patients older or equal to 65 years of age, who receive clopidogrel, will be randomly assigned to undertake surgery under general anesthesia in the first 48 hours. Anesthetics to be used are propofol, fentanyl and rocuronium. Maintenance will be achieved with remifentanyl and propofol (TIVA) and the depth of anesthesia will be monitored by BIS. Morphine will be administered bolus IV immediately postoperatively. General anesthesia Propofol Hip fracture patients older or equal to 65 years of age, who receive clopidogrel, will be randomly assigned to undertake surgery under general anesthesia in the first 48 hours. Anesthetics to be used are propofol, fentanyl and rocuronium. Maintenance will be achieved with remifentanyl and propofol (TIVA) and the depth of anesthesia will be monitored by BIS. Morphine will be administered bolus IV immediately postoperatively. General anesthesia Rocuronium Hip fracture patients older or equal to 65 years of age, who receive clopidogrel, will be randomly assigned to undertake surgery under general anesthesia in the first 48 hours. Anesthetics to be used are propofol, fentanyl and rocuronium. Maintenance will be achieved with remifentanyl and propofol (TIVA) and the depth of anesthesia will be monitored by BIS. Morphine will be administered bolus IV immediately postoperatively. Regional anesthesia Fentanyl Hip fracture patients older or equal to 65 years of age, who receive clopidogrel, will will be randomly assigned undertake surgery under regional anesthesia (spinal) at least 5 days after the discontinuation of clopidogrel. Anesthetics to be used are chirochaine 0.5% and fentanyl. General anesthesia Morphine Hip fracture patients older or equal to 65 years of age, who receive clopidogrel, will be randomly assigned to undertake surgery under general anesthesia in the first 48 hours. Anesthetics to be used are propofol, fentanyl and rocuronium. Maintenance will be achieved with remifentanyl and propofol (TIVA) and the depth of anesthesia will be monitored by BIS. Morphine will be administered bolus IV immediately postoperatively.
- Primary Outcome Measures
Name Time Method Mortality 30 days To compare postoperative 30-day mortality between General anesthesia and Regional anesthesia group
- Secondary Outcome Measures
Name Time Method Adverse events postoperatively 30 days Occurrence of adverse events in both General anesthesia and Regional anesthesia groups, especially respiratory, renal, surgical trauma in 30 days postoperatively.
Re-admissions 30 days Re admissions in both General anesthesia and Regional anesthesia groups in 30 days postoperatively.
Adverse events intraoperatively During operation time frame To check and compare in both General anesthesia and Regional anesthesia groups incidence of low blood pressure (\< 20% from baseline), bradycardia (\<50 bpm), hemorrhage and need of blood transfusions, use of antifibrinolytics intraoperatively
Timed Up and Go Test (TUG) Measurements will be assessed 1, 3 and 6 months postop To determine fall risk and measure the progress of balance, sit to stand, and walking using Timed Up and Go Test (TUG) and compare these attributes between General anesthesia and Regional anesthesia groups 1, 3 and 6 months postoperatively
Major Cardiovascular Events Events will be recorded for both groups from date of surgery postop up to 12 months or date of death from any cause, with intermediate recordings in 1, 3 and 6 months periods in survivors To check and compare between General anesthesia and Regional anesthesia group for major cardiovascular events (arrhythmias, stroke, cardiac arrest, acute myocardial infract, acute respiratory oedema, pulmonary embolism) postoperatively in 30 days and 3, 6, 12 months.
Postoperative analgesic use 30 days Use of analgesics (pethidine, paracetamol), counted in milligrams as a mean per day, from the time patients are transfered to the orthopedic ward until 30 days postop in both General anesthesia and Regional anesthesia groups targeting Numerical Rating Scale score \<4 (range is from 0 to 10 and a higher score indicates greater pain intensity).
Functionality in daily living 6 months To check and compare between both General anesthesia and Regional anesthesia groups 6 months postoperatively functionality using Instrumental Activities of Daily Living scale
EQ-5D-5L (EuroQol group, 5 dimensions, 5 levels) Measurements will be assessed at 1, 3 and 6 months postop With the use of EQ-5D-5L to check and compare between General anesthesia and Regional anesthesia groups 1, 3 and 6 months postoperatively mobility, self-care, usual activities, pain/discomfort and anxiety/depression.
Oxford hip score Measurements will be assessed at 1, 3 and 6 months postop To assess function and pain in both General anesthesia and Regional anesthesia groups 1, 3 and 6 months postoperatively by using Oxford hip score
Change in cognitive status Cognitive function will be measured for both groups on admission (preop), 6 months and 12 months postop To measure and compare, between General anesthesia and Regional anesthesia group, Cognitive status using Mini Mental State Examination and Clock Test before surgery and 6, 12 months postoperatively
Time of hospitalization Time to discharge will be considered the time duration from date of surgery until the date of discharge or date of death from any cause while hospitalised, whichever came first, assessed up to 1 month To check and compare in both General anesthesia and Regional anesthesia groups time to hospital discharge.
Delirium Occurrence of delirium will be measured, for both groups, on admission (preop) and days 2, 3, 4 and 7 postop (two tests per day, morning and evening hours) Occurrence of delirium and comparison between General anesthesia and Regional anesthesia group with the use of Confusion Assessment Method before surgery and in 2, 3, 4 and 7 days postoperatively.
