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

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 ]
  • Space used for 1st attempt, as estimated by palpation or U/S [ Time Frame: Day 1 ]
  • Number of spaces used [ Time Frame: Day 1 ]
  • Dural depth (cm) [ Time Frame: Day 1 ]

Enrollment: 80
Study Start Date: January 2011
Study Completion Date: September 2012
Primary Completion Date: September 2012 (Final data collection date for primary outcome measure)
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.
