Effect of Sumatriptan on the Postoperative Quality of Recovery After Elective Minimally Invasive Craniotomy : Effect of Sumatriptan on the Postoperative Quality of Recovery After Elective Minimally Invasive Craniotomy

Recently there have been changes in the surgical management of many patients who have an unruptured cerebral aneurysm and or cranial nerve neuralgia pain. The surgical technique now consists of a minimally invasive craniotomy that is less invasive with a smaller incision, shorter duration of procedure and in some patients the possibility of going home the same day, Postoperative surgical pain from the incision itself is usually minimal and they are usually managed very well with combination of both opioid and non-opioid analgesics such as fentanyl, morphine, hydromorphone, codeine, oxycocet, oxycontin and acetaminophen. In addition, up to 65% patients undergoing craniotomy may suffer from post craniotomy headache and the incidence may be higher after posterior fossa craniotomy. (1) Patients often complain of severe migraine headache associated with photophobia, nausea and vomiting and general feeling of unwell. These discomforts often delay discharge from the hospital and affect the quality of recovery. (2,3) Post craniotomy surgical pain usually decreases significantly after 24 hours whereas post craniotomy migraine headache, which may be a separate entity, continues for a longer period of time. (4) This migraine headache is in different location from the surgical incision and the conventional treatments of post surgical pain are ineffective against migraine headache.(5) Hence these patients usually suffer a lot after minimally invasive craniotomy. The mechanisms of postoperative migraine are also poorly understood and may be multifactorial including raised intracranial pressure, traction on intracranial blood vessels or meningeal irritation. (6) These factors activate the trigeminal afferent C fibres that reside on pial and dural blood vessels. This causes transmission of pain and release of neurogenic peptides activating an inflammatory cascade causing vasodilation and perivascular inflammation. The loss of cerebrospinal fluid is another factor.(7) With a minimally invasive craniotomy, loss of cerebrospinal fluid is unavoidable as it is needed for better surgical access. Serotonin (5-hydroxytryptophan) is a neurotransmitter that is thought to contribute to the feeling of wellbeing. There are receptors for 5hydroxytryptophan (5-HT) located in the central nervous system especially in the trigeminal nerve both near the dura as well as in brainstem (near the trigeminal nuclei) and also located on vascular endothelium and smooth muscle in meningeal blood vessels as well as in neuronal tissue..
