Randomized Controlled TrialInjection of intrathecal normal saline in decreasing postdural puncture headache.
Postdural puncture headache (PDPH) is the most common and still unresolved postoperative complication of spinal anesthesia. Although there are several positive results of intrathecal saline injection for the treatment of PDPH and prophylaxis after accidental dural puncture, the effect of deliberate intrathecal saline injection before spinal anesthesia has not been examined. The objective of our study was to evaluate the effect of prophylactic administration of intrathecal normal saline in decreasing PDPH. ⋯ Administration of normal saline (5 ml) before intrathecal administration of hyperbaric bupivacaine as a preventive approach is an effective and simple way to minimize PDPH in patients undergoing cesarean section.

Randomized Controlled TrialStroke volume-directed administration of hydroxyethyl starch (HES 130/0.4) and Ringer's acetate in prone position during neurosurgery: a randomized controlled trial.
General anesthesia in the prone position is associated with hypotension. We studied stroke volume (SV)-directed administration of hydroxyethyl starch (HES 130 kDa/0.4) and Ringer’s acetate (RAC) in neurosurgical patients operated on in a prone position to determine the volumes required for stable hemodynamics and possible coagulatory effects. ⋯ The amount of RAC needed in the prone position was 25 % greater. The cumulative dose of 440 ml HES induced a slight disturbance in fibrin formation and clot strength. We suggest cautious administration of HES during neurosurgery.

Observational StudyRelationship of abdominal circumference and trunk length with spinal anesthesia level in the term parturient.
We hypothesized that body shape metrics influence the anatomy of spinal canal and intraabdominal pressure in three dimensions. We explored the effects of abdominal circumference, trunk length, and their combination on the level of spinal anesthesia in the term parturient in this study. ⋯ TL/AC2, which simulated the ratio of the long axis and transection area of the abdomen, was correlated with maximal spinal level, and parturients with low TL/AC2 values tended to have higher dermatomal levels during spinal anesthesia.

Influence of apneic oxygenation on cardiorespiratory system homeostasis.
The aim of this study was to elucidate the magnitude of variations in oxygenation indices and the pattern of hemodynamic changes in response to the net effect of tracheal apneic oxygenation (AO) with a view to define the safe time limit of its application. ⋯ Tracheal AO for 40 min ensures acceptable blood oxygenation, promotes notable hypercapnic acidosis, and consequent transient hemodynamic alterations, which are almost completely reversible after reconnection to the ventilator.
