- 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.

Group Intervention Description group that received dexamethasone (DLSA) 12,5 mg of 0,5 % of levobupivacaine 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. group that received dexamethasone (DLSA) 8 mg of dexamethasone 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. group without dexamethasone (LSA) 12,5 mg of 0,5 % of levobupivacaine 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.
- Primary Outcome Measures
Name Time Method postoperative cognitive change 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 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 Outcome Measures
Name Time Method 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 Assessed using Visual Analogue Scale score and establishing postoperative analgesic requirements
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 Determined form patient's blood plasma assessed by Beckman Coulter AU400 and AU680 orbOlympus Glucose Analyzer 2 devices defined from the laboratory reference points (4,4-6,4)mmol/L equal for each measure point; for single measuring 0,2 ml of patient's blood was taken
Blood loss During the surgical repairment and up to the removal of drainage systems (2nd postoperative day) Determinated by intraoperative blood loss in mililitres, amount of blood in drainage systems in mililitres, transfusion of homologous blood in mililitres
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 Determined from laboratory values of haemoglobin data measured reference points (119-157)g/L equal for each measure point
Number of Participants with pulmonary embolism During surgical reconstruction and during postoperative follow-up of up to ten postoperative days Established by noted pulmonary embolism in the operating room or at the traumatology ward by the ward staff
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 Determined from laboratory values of platelets data in reference points (158-424)10\^9/L equal for each measure point
Number of Participants with heart failure During surgical reconstruction and during postoperative follow-up of up to ten postoperative days Established by noted heart failure in the operating room or at the traumatology ward by the ward staff
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 Determined from laboratory values of haematocrit data in reference points (0,356-0,470)L/L equal for each measure point
Hospitalisation In the time period of up to 30 days Calculated by number of days preoperatively from the day of admission to the day of surgical treatment and postoperatively from the day of surgical treatment to the day of hospital discharge
