Outcome Measures
Primary Outcomes (1)
The dose of chloroprocaine 1% needed for the individual patient for a sensory anesthesia block at or above the T6 dermatome
MLAD of chloroprocaine 1% with 2,5 mcg of sufentanil needed for the individual patient required for a sensory anesthesia at or above the T6 dermatome at the beginning of surgery with no additional epidural anesthesia required during surgery
start of surgery
Secondary Outcomes (7)
Peak block height
during surgery
Time for regression of two segments
during surgery
Ambulation time
From starting hour of spinal anesthesia to hour of first ambulation after the end of surgery measured up to 6 hours after surgery
Time to micturition
From starting hour of spinal anesthesia to hour of first micturition after the end of surgery measured up to 6 hours after surgery
Incidence of side effects (perioperative hypotension, respiratory depression, neurologic deficits)
perioperative
- +2 more secondary outcomes
Study Arms (1)
chloroprocaine 1% injectable solution
EXPERIMENTALProspective, up-down sequential allocation : first patient receives 50mg intrathecal chloroprocaine 1%. An effective result will decrease the test dose of chloroprocaine with 2 mg for the next patient in this study. An ineffective result will increase the test dose of chloroprocaine with 2 mg for the next patient in this study.
Interventions
standard CSE procedure in outpatients for inguinal hernia. The first spinal dose of chloroprocaine 1% to start with is 50mg. This dose has been successfully used for spinal anesthesia in hernia repair outpatients to reach an adequate analgesia. 2,5 microgram of sufentanil will be added for prolongation of the analgesia. The testing interval is 2 mg. Efficacy of the analgesia will be evaluated: Successful : sensory block at or above T6 dermatome bilateral at the beginning of surgery without additional analgesia during surgery. Unsuccessful: sensory block under T6 dermatome bilateral and/or VAPS is more than 10 mm at the beginning of surgery what necessitates additional epidurals analgesia. Patients who indicate an ineffective result will receive a rescue treatment by the administration of 5 ml chloroprocaine 3% epidural every 5 minutes with maximum of 30ml. When CSE fails, general anesthesia will be performed.
Eligibility Criteria
You may qualify if:
- Outpatients for unilateral inguinal hernia repair
- ASA I - II - III
You may not qualify if:
- hypersensitivity to amino-ester local anesthetics, para-aminobenzoic acid or sufentanil
- contraindications to spinal or epidural anesthesia
- bilateral inguinal herniorrhaphy
- extremes of height and weight (BMI 20 or 35 kg/m2, height 150 cm or 185 cm)
