To present a case of postpartum bilateral intracranial subdural hematoma after dural puncture during attempted epidural analgesia for labour. ⋯ It is conceivable that thrombocytopenia together with possible abnormal platelet function increased the risk of subdural hematoma. Alternative diagnoses to PDPH should be considered whenever headache is not posturally related.

The aim of this review of the literature was to evaluate the effectiveness of anesthetics in protecting the heart against myocardial ischemia-reperfusion injury. ⋯ There is increasing evidence of anesthetic agent-induced protection. At present, isoflurane, sevoflurane and morphine appear to be most promising as preconditioning-inducing agents. After the onset of ischemia, propofol could be selected to reduce ischemia-reperfusion injury. Future clinical application depends on the full elucidation of the underlying mechanisms and on clinical outcome trials.

Randomized Controlled Trial Clinical Trial
Laryngeal mask cuff inflation at removal does not affect early postoperative laryngopharyngeal morbidity.
We assessed the effect of cuff inflation of the laryngeal mask airway at removal on sore throat, pharyngeal morbidity and airway complications. ⋯ We conclude that removal of the laryngeal mask airway inflated does not reduce the incidence of sore throat, pharyngeal morbidity or airway complications.

Randomized Controlled Trial Clinical Trial
The LMA-ProSeal is an effective alternative to tracheal intubation for laparoscopic cholecystectomy.
To compare LMA-ProSeal (LMA-PS) with endotracheal tube (ETT) with respect to pulmonary ventilation and gastric distension during laparoscopic cholecystectomy. ⋯ A correctly seated LMA-PS or ETT provided equally effective pulmonary ventilation without clinically significant gastric distension in all non-obese patients. Further studies are required to determine the acceptability of the LMA-PS for laparoscopic cholecystectomy in obese patients.

Randomized Controlled Trial Clinical Trial
Propofol decreases cerebral blood flow velocity in anesthetized children.
Propofol, by virtue of its favourable pharmacokinetic profile, is suitable for maintenance of anesthesia by continuous infusion during neurosurgical procedures in adults. It is gaining popularity for use in pediatric patients. To determine the effects of propofol on cerebral blood flow in children, middle cerebral artery blood flow velocity (Vmca) was measured at different levels of propofol administration by transcranial Doppler (TCD) sonography. ⋯ This study shows that a higher rate of propofol infusion is associated with lower CBFV and MAP values in children. Propofol's cerebral vasoconstrictive properties may be responsible for this finding.
