Summary

The purpose of this study is to investigate the effects of postoperative coffee consumption on postdural puncture headache (PDPH) and analgesic use in women undergoing cesarean section with spinal anesthesia.

Detailed description

Surgical procedures are frequently preferred today. The choice of anesthesia is crucial for patient safety in surgical procedures. Spinal anesthesia is recommended in national and international guidelines and protocols. There are many reasons for the frequent preference for spinal anesthesia. Spinal anesthesia provides better pain control than narcotic analgesics in postoperative pain management, reduces systemic opioid use, and allows for earlier onset of bowel movements in the postoperative period. However, postdural puncture headache can also occur with this method. Postdural puncture headache (PDPH) is one of the most common complications after spinal anesthesia. Current data in the literature indicate a significant incidence of PDPH. Caffeine has a structure similar to adenosine. Therefore, it replaces adenosine by binding to the same receptors as adenosine. Consequently, caffeine can alleviate headaches through its vasoconstrictive effect. Additionally, caffeine can inhibit the synthesis of leukotrienes and prostaglandins to a limited extent. These properties suggest that caffeine may be effective in pain control. However, the effectiveness of caffeine intake in preventing PDPH has not been definitively established. The most effective method used to prevent this complication is epidural blood patching. However, this is an invasive procedure. To avoid the drawbacks of invasive methods, reliable, practical, and cost-effective non-invasive methods should be preferred. Caffeine is believed to have a potential role in the prevention of postdural puncture headache based on its mechanism of action.

Conditions

• Postdural Puncture Headache

Interventions

Type	Name	Description
DIETARY_SUPPLEMENT	Coffee Consumption	The first coffee (2 g Nescafe Gold™ in 200 ml of hot water) will be given to the participant within the first hour after starting oral feeding. The second coffee will be scheduled according to the participant's surgery time, individual preferences, and sleep patterns, taking into account the 3-9 hour half-life of caffeine. Participants will be given coffee two more times in the following 24-hour period. Thus, participants will consume coffee four times in 48 hours.
