Primary Outcome Measures:
  • Number of attempts at intrathecal needle tip placement during spinal anesthesia. [ Time Frame: Day 1 ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • 1. Time to place spinal anesthetic (seconds), measured from introducer placement to confirmation of cerebral spinal fluid (CSF). [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
  • Space used for 1st attempt, as estimated by palpation or U/S [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
  • Number of spaces used [ Time Frame: Day 1 ] [ Designated as safety issue: Yes ]
  • Dural depth (cm) [ Time Frame: Day 1 ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: Ultrasound
Trainees will receive pre-procedure U/S guided examination of the parturient's back.
 Device: Ultrasound examination
Trainees will receive pre-procedure U/S guided examination of the parturient's back.
Other Name: M-turbo
No Intervention: Control
Control group. (Standard practice) Trainees will NOT receive pre-procedure U/S guided examination.

Detailed Description:

Parturients receiving spinal anesthetic for elective Cesarean section will be randomized to have/not have pre-spinal ultrasound examination of their back, prior to spinal insertion by anesthesia trainees.

The hypothesis is that ultrasound visualization of the patient spinal spaces will allow junior residents to correctly place the spinal needle with fewer attempts.

The null hypothesis is that there is no difference in the primary outcome (number of attempts). i.e. the investigators hypothesize that the number of attempts is not affected by ultrasound assistance. The control group will undergo spinal anesthesia with manual palpation, the standard of care.
