Experimental: Spinal Lidocaine Administration
Spinal anesthesia will be induced with isobaric 2% lidocaine and 15 μg fentanyl. The study lidocaine dose will be determined using a 9:1 biased-coin sequential allocation method. For the first participant, the starting dose will be 32 mg of 2% isobaric lidocaine (1.6 mL). If the lidocaine dose provides an unsatisfactory anesthetic, the case will be categorized as a failure. After a failed case, the next participant will receive a lidocaine dose increased by 4 mg. If the lidocaine dose provides satisfactory anesthesia, the next participant's lidocaine dose will determined by a biased allocation method with a 90% chance of maintaining the dose and a 10% chance of decreasing the dose by 4 mg. |
The lidocaine dose will be determined using a 9:1 biased-coin sequential allocation method.
For the first participant, the starting dose will be 32 mg of 2% isobaric lidocaine (1.6 mL).
Two outcomes will be possible: satisfactory or unsatisfactory anesthesia.
