Randomized Controlled Trial Comparative Study Clinical TrialPostoperative pain management after supratentorial craniotomy.
The aim of this study was to compare the analgesic efficacy of three different postoperative treatments after supratentorial craniotomy. Sixty-four patients were allocated prospectively and randomly into three groups: paracetamol (the P group, n = 8), paracetamol and tramadol (the PT group, n = 29), and paracetamol and nalbuphine (the PN group, n = 27). General anesthesia was standardized with propofol and remifentanil using atracurium as the muscle relaxant. ⋯ More cases of nausea and vomiting were observed in the PT group but the difference was not significant (P < .06). In conclusion, pain after supratentorial neurosurgery must be taken into account, and paracetamol alone is insufficient in bringing relief to the patient. Addition of either tramadol or nalbuphine to paracetamol seems necessary to achieve adequate analgesia, with, nevertheless, a larger dose of tramadol to fulfill this objective.

Clinical TrialJugular venous oxygen saturation thresholds in trauma patients may not extrapolate to ischemic stroke patients: lessons from a preliminary study.
The authors' first examinations of 10 patients with severe hemispheric stroke indicate that bedside monitoring of cerebral blood flow (CBF) is of clinical value as a prognostic tool for outcome and as therapy of elevated intracranial pressure (ICP). Jugular venous oximetry, which is easier to handle and provides on-line data, may also be of prognostic value in patients with ischemic stroke. No clinical studies are available on patients with hemispheric infarctions. ⋯ In 8 of 17 pairs of measurements with treated elevated ICP, CMRO2 varied and changes of SjvO2 did not reflect changes in CBF. Jugular bulb oximetry should interpreted with caution in patients with severe hemispheric infarction. Critical thresholds defined in trauma patients may not be extrapolated to ischemic stroke.

Case ReportsUsefulness of monitoring brain tissue oxygen pressure during awake craniotomy for tumor resection: a case report.
Awake craniotomy is indicated for surgical resection of tumors located near eloquent areas of the brain. The anesthetic technique is based on a combination of local anesthesia, sedation, and analgesia. Usually only clinical parameters are assessed and no other cerebral oxygenation monitoring techniques are applied. ⋯ On arrival at the intensive care unit, mixed dysphasia and slight weakness of the right arm were noted. Three weeks after surgery, the patient's speech is improving and the motor deficit has disappeared. This case suggests a possible role of PtiO2 in awake craniotomy as an aid in detecting intraoperative adverse events, but further experience with PtiO2 in this setting is needed.
