Background:
Post-craniotomy headache (PCH) pain is common among patients undergoing craniotomy and is associated with increased perioperative morbidity and mortality. It is often undertreated due to the various flaws in the agents used for PCH. The aim of this study was to describe the efficacy of current pain management practices for patients undergoing elective craniotomy.
Methods:
This was a single center, retrospective study in adults undergoing elective craniotomy for neoplasm and epilepsy who had a post-operative length of stay of 48 h or greater. The primary objective of this study was to describe the efficacy of current pain management practices. Secondary objectives were to evaluate the relationship between pain control and hospital length of stay (LOS), to identify factors associated with uncontrolled pain, and to assess where in the post-operative course uncontrolled pain occurred.
Results:
One hundred patients were included in the study, with 75 patients undergoing craniotomy for neoplasm excision and 25 for epilepsy procedures. Median pain scores were significantly higher on postoperative day (POD) 0 compared to POD 1 through 3 (P = 0.043), however there was no significant difference in maximum pain scores among post-operative days (P = 0.629). No correlation existed between LOS and maximum pain score (R = 0.065, P = 0.520). Thirty-three patients (33 %) experienced uncontrolled pain, most frequently occurring on POD 0 and 1. Female sex (P = 0.011), prior history of migraines (P = 0.014), younger age (P < 0.001), and craniotomy for epilepsy procedures (P < 0.001) were associated with uncontrolled pain.
Conclusion:
PCH pain was well-controlled with current pain management practices, with the highest frequency of uncontrolled pain occurring on POD 0 and 1. Optimization of PCH pain management in patients with identified risk factors is warranted, and future studies evaluating PCH pain in larger, multicenter studies are needed.
