Interruption of daily caffeine consumption can cause caffeine withdrawal headache. As headache ranks among the most frequent minor postoperative sequelae, the impact of perioperative substitution of caffeine on the incidence of postoperative headache was evaluated. Forty patients undergoing minor surgical procedures with general anaesthesia were randomly allocated to receive either placebo or caffeine tablets at a dosage equal to their individual average daily caffeine consumption. Daily dietary intake was calculated based on an average week-day consumption using conversion factor from previously published sources. The patients were instructed at the preoperative visit to abstain from all external sources of caffeine. Compliance with these dietary restrictions was verified by blood samples obtained immediately before the surgical procedure and on postoperative day 1. The patients were assessed for headache using a standardised checklist immediately before induction of anaesthesia, on the evening of the day of surgery and on the morning of postoperative day 1. Ten patients (50%) who received placebo reported headaches, which persisted in seven patients (35%) until the next day. No patient receiving caffeine substitution therapy reported headache following surgery, and only one complained of headache on postoperative day 1. We suggest that the prophylactic administration of caffeine tablets might be considered for surgical patients who are accustomed to a high daily intake of caffeine.
