Caffeine Intake Inrelation to Perioperative Analgesic Consumption

Caffeine is the most widely consumed psychoactive drug in the world. Natural sources of caffeine include coffee, tea, and chocolate. Synthetic caffeine is also added to products to promote arousal, alertness, energy, and elevated mood.

We designed this prospective observational study to determine if caffeine consumption would influence intraoperative analgesic consumption

About this study

Caffeine is a well-known natural compound present in various plant products. Caffeine is an integral component of several daily drinks, including tea, coffee, soft drinks, and energy drinks [1]. (e consumption habits of these caffeinated drinks have facilitated the wide distribution of and dependence on caffeine. For instance, 89% of the US adult population has an average caffeine intake of 200 mg/day [2]. Among the multiple effects and side effects, caffeine also has an analgesic action and is used to reduce pain in several pharmaceutical forms as an adjuvant [1]. Several studies have reported a role for caffeine in controlling pain and suggested that caffeine may block the central processing of pain signals in the brain and enhance the body's natural pain resistance pathways [3]. In addition, Overstreet et al. found that habitual caffeine consumption diminishes pain sensitivity in a laboratory setting [4]
