Observational Study[Perioperative central venous oxygen saturation and its correlation with mortality during cardiac surgery: an observational prospective study].
Cardiac surgery can produce persistent deficit in the ratio of Oxygen Delivery (DO2) to Oxygen Consumption (VO2). Central venous oxygen Saturation (ScvO2) is an accessible and indirect measure of DO2/VO2 ratio. ⋯ Early intraoperative ScvO2 <70% indicated a higher risk of death. A perioperative reduction of ScvO2 was observed in patients undergoing cardiac surgery, with high intraoperative and lower postoperative levels.

Case Reports[Self-applied sphenopalatine ganglion block for postdural puncture headache: four case reports].
The Sphenopalatine Ganglion Block (SGB) is an effective, low-risk treatment option for Postdural Puncture Headache (PDPH) refractory to conservative management. ⋯ The novel approach described in this report has minimal risks of discomfort or injury to the nasal mucosa. It is quick to apply and can be administered by the patient himself.
