Outcomes
Primary Outcome Measures
Sensory and motor block
Sensory and motor block produced by the spinal anaesthesia will be assessed prior the procedure to define readiness for surgery and then once the procedure is over, sensory and motor block levels will be assessed one more time to follow up the block regression times. Motor block will be assessed with Bromage scale (0: no motor block, 1: hip blocked; 2: hip and knee blocked; 3: hip, knee and ankle blocked). Sensory block will be assessed using loss of pinprick sensation. The onset of surgical anesthesia is defined as loss of pinprick sensation at ≥ T10 with a Bromage score ≥ 2.
Secondary Outcome Measures
first mobilisation, first urination and first analgesic times
all patients will be followed up during the first postoperative 24 hours to assess the first mobilisation, first voiding and first analgesic requirement times.

5. Study Description
Brief Summary
The aim of this study was to compare the effects of two different doses of intrathecal morphine (0.1 mg and 0.4 mg) combined with 7.5 mg of heavy bupivacaine on postoperative block regression times, postoperative analgesia and the severity of side effects, for inguinal hernia repairs.
Detailed Description
The purpose of this study was to compare spinal anesthesia with low dose heavy bupivacaine combined with 0.1 mg or 0.4 mg of morphine in inguinal hernia repair surgeries. Anesthesia onset time (sensory and motor blocks) as well as postoperative recovery (first mobilisation, first voiding) time were compared. Also the postoperative pain management and side effects (nausea, vomiting and pruritus) were assessed.

Primary Outcome Measure Information:
Title
Sensory and motor block
Description
Sensory and motor block produced by the spinal anaesthesia will be assessed prior the procedure to define readiness for surgery and then once the procedure is over, sensory and motor block levels will be assessed one more time to follow up the block regression times. Motor block will be assessed with Bromage scale (0: no motor block, 1: hip blocked; 2: hip and knee blocked; 3: hip, knee and ankle blocked). Sensory block will be assessed using loss of pinprick sensation. The onset of surgical anesthesia is defined as loss of pinprick sensation at ≥ T10 with a Bromage score ≥ 2.
Time Frame
The change in motor block and sensory block levels will be assessed after performing spinal block, every 5 minutes for 30 minutes and then at the end of the procedure.
Secondary Outcome Measure Information:
Title
first mobilisation, first urination and first analgesic times
Description
all patients will be followed up during the first postoperative 24 hours to assess the first mobilisation, first voiding and first analgesic requirement times.
Time Frame
after the procedure, during the first 24 hours
Other Pre-specified Outcome Measures:
Title
postoperative nausea, vomiting and pruritus
Description
All patients will be followed up for the first postoperative 24 hours to determine the nausea, vomiting and pruritus incidences.
Time Frame
after the procedure, during the first 24 hours
