[Effects of intravenous vasopressor on spread of spinal anesthesia with 0.5% hyperbaric bupivacaine for caesarean delivery].

Background: It is known that when isobaric bupivacaine is applied for Caesarean delivery, phenylephrine is superior to ephedrine in preventing rostral spread of spinal anesthesia. In this study, we prospectively investigated whether phenylephrine can prevent rostral spread of spinal hyperbaric bupivacaine.

Methods: We randomly divided 32 patients undergoing Caesarean delivery into two groups: phenylephrine group and ephedrine group.

Lateral position prevents respiratory occlusion during surgical procedure under general anesthesia in the patient of huge anterior mediastinal lymphoblastic lymphoma.

Lymphoblastic lymphoma, an aggressive mediastinal mass, is recognized as serious threat to the patient in developing cardiac tamponade or airway obstruction. Surgical procedure is often required to relieve clinical emergency and to establish prompt pathological diagnosis. However, in such a patient, acute respiratory occlusion in the spine position can be a life-threatening complication during general anesthesia.

[Intraoperative management for a patient with heparin-induced thrombocytopenia (HIT) undergoing off-pump coronary bypass surgery using argatroban, a direct thrombin inhibitor].

HIT type II is one of the severe complications of heparin therapy. The antibody for the heparin-PF 4 complex, which causes thrombocytopenia of less than 100 x 10(3).microliter-1, thrombosis and DIC-like symptoms, is produced.
