Prevention and control of postoperative nausea and vomiting in post-craniotomy patients.

Postoperative nausea and vomiting (PONV) are the most frequent side-effects in the postoperative period, impairing subjective well-being and having economic impact due to delayed discharge. However, emetic symptoms can also cause major medical complications, and post-craniotomy patients may be at an increased risk. A review and critical appraisal of the existing literature on PONV in post-craniotomy patients, and a comparison of these findings with the current knowledge on PONV in the general surgical population, leads to the following conclusions: (1) Despite the lack of a documented case of harm caused by retching or vomiting in a post-craniotomy patient, the potential risk caused by arterial hypertension and high intra-abdominal/intra-thoracic pressure leading to high intracranial pressure, forces to avoid PONV in these patients.

Pain management after craniotomy.

Fear of the side effects of analgesic drugs frequently leads to the under-treatment of post-craniotomy pain. Nevertheless, this pain continues to be commonly observed, is frequently severe, and, if unrelieved, may cause distress for the neurosurgical patient and serious complications for the operative brain. We review recent evidence-based data on pain therapy after intracranial surgery.
