BACKGROUND A decreased lumbosacral subarachnoidal space volume is a major factor in the cephalad intrathecal spread of local anesthetics in term parturients and their subarachnoidal space is decreased due to the compressive effect of huge uteri. Therefore, they show a higher level of sensory block and hypotensive episodes. The purpose of this study is to(More)
BACKGROUND Subarachnoid block is a widely used technique for cesarean section. To improve the quality of analgesia and prolong the duration of analgesia, addition of intrathecal opioids to local anesthetics has been encouraged. We compared the effects of sufentanil 2.5 µg and 5 µg, which were added to intrathecal hyperbaric bupivacaine. METHODS We(More)
BACKGROUND Acute kidney injury (AKI) is associated with high morbidity and mortality. Recombinant human erythropoietin has been shown to exert cytoprotection against ischemia. This study examined the effect of erythropoietin in preventing AKI during thoracic aortic surgery with moderate hypothermic circulatory arrest. METHODS In this double-blind,(More)
BACKGROUND Shivering is a frequent event during the perioperative period. We performed a prospective, randomized, double-blind study to determine whether intrathecal meperidine (0.2 mg/kg) decreases the incidence and intensity of shivering after spinal anesthesia for transurethral operations. METHODS Fifty patients scheduled for elective transurethral(More)
We experienced difficulty in ventilating the lungs of a patient after tracheal intubation. After intubation, an insufficient amount of tidal volume (V(T)) was delivered to the patient and the fiberoptic bronchoscopic examination identified partial abutment of the endotracheal tube (ETT) orifice against the tracheal wall. After various attempts to correctly(More)
Sodium nitroprusside (SNP) is an anti-hypertensive drug, commonly used to decrease the systemic vascular resistance and lower the blood pressure. When the amount of cyanide generated by the SNP exceeds the metabolic capacity for detoxification, cyanide toxicity occurs. Under general anesthesia and cardiopulmonary bypass (CPB), it may be difficult to detect(More)
