Why the study?

Does body tilt affect heart rate during spinal anesthesia in unpremedicated patients?

Population

40 unpremedicated patients undergoing tetracaine spinal anesthesia

Discussion

Implication

Head-up tilt during spinal anesthesia warrants BP monitoring; leaves open baroreflex preservation across anesthesia depths.

Structured PICO

Does body tilt affect heart rate during spinal anesthesia in unpremedicated patients?

Population

40 unpremedicated patients undergoing tetracaine spinal anesthesia

Intervention

10-degree head-up and 10-degree head-down body tilt during low (T-10 +/- 0.2, n=20) and high (T-4 +/- 0.2, n=20) analgesic levels of tetracaine spinal anesthesia

Outcome

Heart rate (HR)surrogate

Heart rate responses to head-up body tilt during spinal anesthesia are mediated mainly by arterial baroreceptors and are not impaired by light sedation.
