Overview
Brief Summary
Spinal anesthesia blocks acute pain in older patients with femur fracture. Delirium is a common complication seen after femur fracture, affecting approximately 10-16% of patients. It is associated with increased mortality at 1st year, delayed rehabilitation efforts, prolonged length of hospital stay, poorer functional outcomes, and increased risk of nursing home placement.
Intrathecal dexamethasone administration improves quality of anesthesia in patients with femur fracture compared to conventional spinal anesthesia.
Detailed Description
The aim of this research was to establish the influence of intrathecal dexamethasone administration in spinal anaesthesia with levobupivacaine on postoperative pain and changes of consciousness, values of cortisol levels and quality of treatment for patients with femoral fractures compared to spinal anaesthesia with only local anaesthetic. The study was planned as a prospective, observational, randomised clinical trial. A total of 60 patients ASA2 and ASA3 status, scheduled for surgical procedures were sorted into two groups and underwent surgery in spinal anesthesia with levobupivacaine with or without dexamethsone.

Arms & Interventions
group that received dexamethasone (DLSA)
The study group of 30 patients ASA status 2 or 3 received 8 mg of dexamethasone with 12,5 mg of 0,5% of levobupivacaine intrathecally for surgical reconstruction of proximal femoral fracture. Spinal anaesthesia was performed in sitting position using middle approach in intervertebral space L2-L3 or L3-L4 with spinal needles 22-27 GA.
Intervention: 8 mg of dexamethasone
group that received dexamethasone (DLSA)
The study group of 30 patients ASA status 2 or 3 received 8 mg of dexamethasone with 12,5 mg of 0,5% of levobupivacaine intrathecally for surgical reconstruction of proximal femoral fracture. Spinal anaesthesia was performed in sitting position using middle approach in intervertebral space L2-L3 or L3-L4 with spinal needles 22-27 GA.
Intervention: 12,5 mg of 0,5 % of levobupivacaine
group without dexamethasone (LSA)
The control group of 30 patients ASA status 2 or 3 received 12,5 mg of 0,5% of levobupivacaine intrathecally for surgical reconstruction of proximal femoral fracture. Spinal anaesthesia was performed in sitting position using middle approach in intervertebral space L2-L3 or L3-L4 with spinal needles 22-27 GA.
Intervention: 12,5 mg of 0,5 % of levobupivacaine
Outcomes
Primary Outcomes
postoperative cognitive change
Time Frame: Confusion Assessment Method scoring was assessed in 4 measure points: 1. one hour after surgery, 2. on the 3rd postoperative day at 9 am, 3. on the 5th postoperative day at 9 am, 4. on the 10th postoperative day at 9 am
Assessed using a simplified Confusion Assessment Method scoring scale, a clinical instrument for delirium assessment used by non-psychiatric medical staff after surgery for excluding delirium. Delirium is defined in terms of 4 possible diagnostic criteria (1. acute onset or fluctuating course; 2- inattention; 3- disorganised thinking; 4- altered level of consciousness (may be defined as alert, lethargic, stupor or coma cognitive state)) and is defined as present when 1 plus 2 and either 3 or 4 diagnostic criteria are positive.
cortisol concentrations changes
Time Frame: Measured in 5 measure points: 1. one hour before surgery, 2. one hour after surgery, 3. on the 3rd postoperative day at 6 am, 4. on the 5th postoperative day at 6 am, 5. on the 10th postoperative day at 6 am
Determined from patient's blood plasma assessed by Roche Elecsys Immunoassay System and defined from the laboratory reference points (185-624)nmol/L equal for each measure point; for single measuring 0,5 ml of patient's blood was taken
Secondary Outcomes
- perioperative pain intensity: Visual Analogue Scale score(Visual Analogue Scale scoring (scores: 0-10) was assessed in 5 measure points every 3 hours when patient was awake: 1. 1 h before surgery, 2. 1 h after surgery, 3. on the 3rd postoperative day, 4. on the 5th postoperative day, 5. 10th postoperative day)
- glucose concentrations changes(Measured in 5 measure points (units: mmol/L): 1. one hour before surgery, 2. one hour after surgery, 3. on the 3rd postoperative day at 6 am, 4. on the 5th postoperative day at 6 am, 5. on the 10th postoperative day at 6 am)
- Blood loss(During the surgical repairment and up to the removal of drainage systems (2nd postoperative day))
- Haemoglobin changes(Assessed in 5 measure points: 1.one hour before surgery, 2. one hour after surgery, 3. on the 3rd postoperative day at 6 am, 4. on the 5th postoperative day at 6 am, 5. on the 10th postoperative day at 6 am)
- Number of Participants with pulmonary embolism(During surgical reconstruction and during postoperative follow-up of up to ten postoperative days)
- Platelets changes(Assessed in 5 measure points: 1.one hour before surgery, 2. one hour after surgery, 3. on the 3rd postoperative day at 6 am, 4. on the 5th postoperative day at 6 am, 5. on the 10th postoperative day at 6 am)
- Number of Participants with heart failure(During surgical reconstruction and during postoperative follow-up of up to ten postoperative days)
- Haematocrit changes(Assessed in 5 measure points: 1.one hour before surgery, 2. one hour after surgery, 3. on the 3rd postoperative day at 6 am, 4. on the 5th postoperative day at 6 am, 5. on the 10th postoperative day at 6 am)
- Hospitalisation(In the time period of up to 30 days)
- Number of Participants who underwent surgical procedure during first 48 hours from admission(Calculated in hours after the patient's admission to the hospital's Emergency Department to the point of surgical reconstruction in the time period up to 48 hours)
