Characteristics related to the sensory block level

Characteristic	Value
Ts (sec)	147.9±23.6 (100-219)
Smax (pin-prick)	T 9.2±1.8 (T4-L1)
Smax (cold)	T 9.2±1.8 (T4-L1)
Number of dermatomes blocked (pin-prick)	13.9±1.7
Number of dermatomes blocked (cold)	14.0±1.7
Tmax (pin-prick) (min)	9.5±2.8 (2.5-17.5)
Tmax (cold) (min)	8.4±2.6 (2.8-17.5)

Values are mean±SD, median [IQR] or (range); Ts=time to put patient supine after intrathecal injection, Smax=Maximum level of sensory block (sensory modality), Tmax=time to achieve the Smax after intrathecal injection (sensory modality)
