No results posted yet for this study

Summary

This study is designed to determine the frequency of Tuffier's line overestimation (2 lumbar levels or more) when the palpation method is used in obese parturients at term in the lateral position compared to the sitting position.

Hypothesis: The L3-L4 intervertebral space identified by the palpation method will be two levels higher than the level determined by ultrasonography (US) more often in the lateral than in the sitting position.

Conditions

  • Pregnancy
  • Obesity
  • Obstetrical Anesthesia

PROCEDURE

L3-L4 location: Palpation method confirmed by US

An anesthesiologist will locate the L3-L4 space using the palpation method (Tuffier's line). An investigator trained in US imaging will proceed to the US exam of the spine specifically aiming to identify the L3-L4 intervertebral space. The investigator will note if the same level was identified and if not, which one was according to the US exam.
