Sensory, motor and analgesic effects of spinal anesthesia Surgery
Conditions
Interventions
Patients are allocated randomly to one of two groups using sealed envelopes: Group S3F (n = 65) receive 3 mg (0.6 ml) of spinal 0.5 % hyperbaric bupivacaine along with 10 µg (0.2 ml) to a total volume

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Duration of sensory block is regarded as the primary variable. Level and duration of sensory block is measured using dermatomes and alcohol swab at 10 min after dural puncture and, at the end of surgery, in postoperative ward every 30 minutes until full resolution of the block. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Demographics using patient records (age, gender, type of surgery) at patient arrival. 2. Duration of anaesthesia measured using time record at time from dural puncture until patient left the operating room. 3. Duration of surgery measured using time record from the start to the end of surgery. 4. Rate of success and failed block determined as the ability to make a dural puncture at the start of anaesthesia. 5. Level and duration of motor block measured using Bromage scale at 10 minutes after dural puncture, at the end of surgery, in postoperative ward every 30 minutes until full resolution of the block. 6. Time to voiding measured using time record at the moment of first postoperative urination. 7. Time to ambulation measured using time record at the time of the patient's ability to walk without assistance. 8. The rate of postoperative complications measured using patient complaints and recovery records: pruritus measured as patient complaint after resolution of the spinal block; urinary retention measured using patient complaints and recovery records on 0-2 point scale (where 0 = normal urination, 1 = difficult spontaneous urination, 2 = unable to urinate and catheterisation is required) at patient discharge. 9. Level of pain using VAS scale 0-100 at 1.5, 2, 2.5, 3, 6, 9, 12, 18 and 24 h postoperatively at rest and movement. 10. Consumption of analgesics measured counting the total doses of opioid and non-opioid analgesics consumed over 24 h postoperatively. 11. Quality of anaesthesia according to the patient and medical staff is measured using a scale of 0 – 2 scores at patient discharge from the operating room (surgeon and anaesthesiologist) and at patient discharge from the hospital (surgical ward nurse, patient). 12. Data collection is continued until patient discharge or until 24 h postoperatively and is stopped at 24 h after surgery. | — |
