PRIMARY outcome

Timeframe: Baseline, from injection and up to 4 hours after injection

Population: Applies to experimental site only.

Time to resolution of subarachnoid block (minutes from injection) will be measured for the device on the (non-operative) thigh.

Outcome measures

Measure
Cooling Device Placed
n=9 Participants
A basic medical grade cooling pad will be secured to the non operative leg. Intermittent coolness will be assessed and subject will inform recovery room staff when sensation returns. cooling device: device placed on patient in recovery on non surgical side to determine resolution of spinal anesthetics.
Block Recovery Time (Device)
40.7 minutes
Standard Deviation 33.32

PRIMARY outcome

Timeframe: Baseline, from injection and up to 4 hours after injection

Population: this outcome applies to the standard of care site only

Time to resolution of subarachnoid block (minutes from injection) will be measured for the standard nursing pinprick testing on the same (non-operative) thigh.
