Effect of the Height of the Operating Table During Spinal Anesthesia

Summary

The purpose of this study is to analyze the accuracy of needle insertion and the discomfort during different ergonomic conditions faced by anesthesiologists during spinal anesthesia. In particular,the investigators intend to compare the angles between the patients' back and the inserted spinal needle in the coronal plane at different operating table heights.

Conditions

• Anesthesia, Spinal [E03.155.086.331]
• Operating Tables [E07.325.662]

Interventions

PROCEDURE

Umbilicus

Depending on the height of the operating table, the insertion angle of the spinal needles would be vary. The investigators intend to find the optimal angle and the height of the table to provide that. The height of the operating table which set at the needle insertion point of anesthetists; the level of umbilicus

PROCEDURE

Lowest rib margin

The height of the operating table which set at the needle insertion point of anesthetists; the level of lowest rib margin

PROCEDURE

Xiphoid

The height of the operating table which set at the needle insertion point of anesthetists; the level of xiphoid

PROCEDURE

Nipple

The height of the operating table which set at the needle insertion point of anesthetists; the level of nipple

DRUG

Umbilicus Bupivacaine

If freely flowing of CSF is detected, appropriate dose of MARCAINE was injected in all interventional groups.
