Caffeine and Sleep in Preventing Post-spinal Headache: Which One is More Effective?

Area of Science:

• Anesthesiology and Perioperative Medicine
• Neurology
• Sleep Medicine

Background:

• Post-spinal headache is a common complication following spinal anesthesia.
• Caffeine is often recommended for prevention but may disrupt sleep.
• The relationship between sleep, caffeine, and post-spinal headache is not well-established.

Purpose of the Study:

• To investigate the influence of caffeine consumption and sleep on post-spinal headache.
• To identify key predictors of post-spinal headache in patients undergoing spinal anesthesia.

Main Methods:

• A descriptive, cross-sectional study involving 425 patients undergoing elective surgery.
• Data collected via interviews using validated scales for sociodemographics, sleep quality, insomnia severity, and pain.
• Binary logistic regression analysis used to determine factors affecting post-spinal headache.

Main Results:

• Insomnia severity (OR=1.234), poor sleep quality (OR=0.992), and shorter postoperative sleep duration (OR=0.619) significantly predicted post-spinal headache.
• Not consuming coffee (OR=0.035) was also a significant predictor.
• These factors explained 57.7% of the variance in post-spinal headache.

Conclusions:

• Insomnia severity and sleep quality are more influential than caffeine in preventing post-spinal headaches.
• Poor sleep and insomnia may increase the incidence and severity of post-spinal headaches.
• Caffeine's role in post-spinal headache prevention may be less significant than its potential negative impact on sleep quality and insomnia.
