Study Arms (1)
Chloroprocaine dose
EXPERIMENTALInitial Patient (A#X) 45mg (1.5mL) of Chloroprocaine 3% (Nesacaine - Fresenius Kabi), will be drawn up into a 3 ml syringe (a 1 ml 'TB syringe' will be used to aspirate the drug in aliquots to ensure accuracy). The following additive will be added: 10 mcg (0.2ml) of fentanyl (50 mcg/ml) 0.3 ml of sterile 0.9% sodium chloride Thus the total volume in the syringe will be 2 ml. Study drugs will be prepared by one anesthesiologist (un-blinded) and administered by another anesthesiologist (blinded). Subsequent Patient (A#X+1) The dose of Chloroprocaine 3% based on outcome from prior subject and calculations mentioned previously will be added to 10 mcg (0.2ml) of fentanyl (50 mcg/ml). Sterile 0.9% sodium chloride will be added until the total volume in the syringe is 2 ml.

- Masking Details
- The solutions and their administration procedures are identical to those used outside this research and are almost exclusively used for patients requiring spinal anesthesia for cervical cerclage. The only deviation involves diluting the chloroprocaine with saline so that study solutions are of equal volume to maintain blinding.

Data Sharing
- IPD Sharing
- Will share
- Shared Documents
- STUDY PROTOCOL, SAP, ICF, CSR, ANALYTIC CODE
- Time Frame
- The study protocol will be shared between institutions and will be identical. The SAP, CSR, and analytic code is also shared and identical. The ICF however will be different and each institution will use its own version of the consent form.
- Access Criteria
- Shared data will be stored in REDCap to be used between institutions. The data will be shared by the PIs and all members listed on the Duke IRB submission both at Duke and UAMS. All statistical analyses will be done at Duke.
IPD will be shared between institutions insofar as it is required for the sequential study design when evaluating the primary outcome. The dose of chloroprocaine used for each procedure as well as the outcome of the surgery will dictate the dosing for the next patient at either institution. PHI will not be shared however.
